There is a lack of published work on RIs for newborn buffaloes. Establishing blood gas and serum biochemical RIs for newborn buffaloes is important for monitoring health. This study establishes blood gas and serum biochemical RIs of newborn buffaloes. Twenty-eight newborn buffaloes, 10-30 days old, were selected. Thirty blood biochemical variables were analyzed. The Anderson-Darling test was used to assess the normality of the distribution. The Dixon test and the Tukey test were used to identify outliers. The RI and 90% CI were determined using standard and robust methods and the Box-Cox transformation. A total of 30 RIs for healthy buffalo calves have been reported in this study. RIs for blood gas variables were reported for pH, partial pressure of oxygen (pO 2 ), partial pressure of carbon dioxide (pCO 2 ), saturation of O 2 (SO 2 ), bicarbonate (cHCO 3 - ), base excess (BE), total carbon dioxide (ctCO 2 ), and anion gap (AG). RIs for serum biochemical variables were reported for glucose (GLU), direct bilirubin (DB), total bilirubin (TB), AST, ALP, GGT, CK, LDH, creatinine (CREA), urea, cholesterol (CHOL), triglycerides (TG), Ca, P, Mg, Na, K, iCa, Cl, iron, total protein (TP), and albumin (ALB). This is the first reported study covering complete serum chemistry and blood gas RIs for healthy 1-month-old Murrah buffaloes. © 2018 American Society for Veterinary Clinical Pathology.

Full Text Available Introduction. The relationships of the biochemical components in seminal plasma and serum, and their origins and physiological effects in male reproductive system have been poorly understood. Methods. Based on the calibration and quality control measures, 26 biochemical markers, in seminal plasma and serum samples from 36 male infertility patients with nonazoospermia were detected and compared. Results. Only PA was undetectable in all seminal plasma samples. There were significant differences of all other 24 biochemical markers in seminal plasma and serum (P<0.05 except for UA (P=0.214. There were rich proteins in seminal plasma, and globulin accounted for about 90%. There were also abundant enzymes in seminal plasma, and the activities of ALT, AST, AKP, GGT, LDH, CK, and αHBDH in seminal plasma were significantly higher than those in serum while ADA was inversely lower. There were relatively low levels of Glu, TG, TC, and hsCRP in seminal plasma, but Glu was undetectable in 8 of 36 cases. Conclusions. The differences of the levels of biochemical markers in seminal plasma and serum might be associated with the selective secretion of testis, epididymis and male accessory glands, and the specific environment needed for sperm metabolism and function maintenance.

To evaluate serum concentrations of biochemical markers and survival time in dogs with protein-losing enteropathy (PLE). Prospective study. 29 dogs with PLE and 18 dogs with food-responsive diarrhea (FRD). Data regarding serum concentrations of various biochemical markers at the initial evaluation were available for 18 of the 29 dogs with PLE and compared with findings for dogs with FRD. Correlations between biochemical marker concentrations and survival time (interval between time of initial evaluation and death or euthanasia) for dogs with PLE were evaluated. Serum C-reactive protein concentration was high in 13 of 18 dogs with PLE and in 2 of 18 dogs with FRD. Serum concentration of canine pancreatic lipase immunoreactivity was high in 3 dogs with PLE but within the reference interval in all dogs with FRD. Serum α1-proteinase inhibitor concentration was less than the lower reference limit in 9 dogs with PLE and 1 dog with FRD. Compared with findings in dogs with FRD, values of those 3 variables in dogs with PLE were significantly different. Serum calprotectin (measured by radioimmunoassay and ELISA) and S100A12 concentrations were high but did not differ significantly between groups. Seventeen of the 29 dogs with PLE were euthanized owing to this disease; median survival time was 67 days (range, 2 to 2,551 days). Serum C-reactive protein, canine pancreatic lipase immunoreactivity, and α1-proteinase inhibitor concentrations differed significantly between dogs with PLE and FRD. Most initial biomarker concentrations were not predictive of survival time in dogs with PLE.

The objective of this observational study is to describe clinical, haematological and serum biochemical findings of horses affected with alfalfa dodder (Cuscuta campestris) toxicity. Twenty horses naturally exposed to alfalfa dodder toxicity were examined and information was collected on history and clinical signs. Physical examination was done on horses in the premises (n=20), and venous blood samples of 12 horses were submitted for haematology and serum biochemical examination for each horse. Abnormal clinical signs started around 36 hours after horses were fed the contaminated alfalfa. Abnormal signs were seen in 11 horses and those included diarrhoea (n=8), decreased appetite (n=7), neurological signs (n=4) and abdominal pain (n=1). Some horses had multiple clinical signs of the above. The results of complete blood cell count revealed leukocytopenia, neutropenia and thrombocytopenia. Serum biochemical analysis revealed decreased ALP, AST and CPK levels and increased direct bilirubin level. The used alfalfa was stopped immediately and a different alfalfa from a new container that did not contain any weeds was fed. Horses on the premises were observed closely, and the abnormal clinical signs resolved within three days. No treatment was implemented. Knowledge about toxicity of horses by Cuscuta species is scarce in the English veterinary literature and very limited.

Full Text Available Introduction To analyze the association between serum levels of folate and risk of biochemical recurrence after radical prostatectomy among men from the Shared Equal Access Regional Cancer Hospital (SEARCH database. Materials and Methods Retrospective analysis of 135 subjects from the SEARCH database treated between 1991-2009 with available preoperative serum folate levels. Patients' characteristics at the time of the surgery were analyzed with ranksum and linear regression. Uni- and multivariable analyses of folate levels (log-transformed and time to biochemical recurrence were performed with Cox proportional hazards. Results The median preoperative folate level was 11.6ng/mL (reference = 1.5-20.0ng/mL. Folate levels were significantly lower among African-American men than Caucasians (P = 0.003. In univariable analysis, higher folate levels were associated with more recent year of surgery (P < 0.001 and lower preoperative PSA (P = 0.003. In univariable analysis, there was a trend towards lower risk of biochemical recurrence among men with high folate levels (HR = 0.61, 95%CI = 0.37-1.03, P = 0.064. After adjustments for patients characteristics' and pre- and post-operative clinical and pathological findings, higher serum levels of folate were independently associated with lower risk for biochemical recurrence (HR = 0.42, 95%CI = 0.20-0.89, P = 0.023. Conclusion In a cohort of men undergoing radical prostatectomy at several VAs across the country, higher serum folate levels were associated with lower PSA and lower risk for biochemical failure. While the source of the folate in the serum in this study is unknown (i.e. diet vs. supplement, these findings, if confirmed, suggest a potential role of folic acid supplementation or increased consumption of folate rich foods to reduce the risk of recurrence.

Chronic cholangiopathies, such as primary and secondary sclerosing cholangitis, are progressive disease entities, associated with periportal accumulation of inflammatory cells, encompassing monocytes and macrophages, peribiliary extracellular matrix (ECM) deposition and ductular reaction (DR). This study aimed to elucidate the relevance of macrophages in the progression of chronic cholangiopathies through macrophage depletion in a 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) mouse model. One group of mice received a single i.p. injection of Clodronate encapsulated liposomes (CLOLipo) at day 7 of a 14 day DDC treatment, while control animals were co-treated with PBSLipo instead. Mice were sacrificed after 7 or respectively 14 days of treatment for immunohistochemical assessment of macrophage recruitment (F4/80), ECM deposition (Sirius Red, Laminin) and DR (CK19). Macrophage depletion during a 14 day DDC treatment resulted in a significant inhibition of ECM deposition. Porto-lobular migration patterns of laminin-rich ECM and ductular structures were significantly attenuated and a progression of DR was effectively inhibited by macrophage depletion. CLOLipo co-treatment resulted in a confined DR to portal regions without amorphous cell clusters. This study suggests that therapeutic options selectively directed towards macrophages might represent a feasible treatment for chronic cholestatic liver diseases. PMID:27618307

Objective: To explore the clinical significance of changes of serum bone metabolic biochemical markers levels in elderly subjects with subclinical hypothyroidism. Methods: Serum S-BGP (with RIA), TSH, FT 4 (with ECLIA), total cholesterol (TC), triglyceride (TG), HDL, LDL, ApoA 1 , ApoB and Ca 2+ (with biochemical methods) were measured in 30 elderly subjects with subclinical hypothyroidism and 30 controls. Results: The serum levels of S-BGP and calcium in elderly subjects with subclinical hypothyroidism (2.78 ± 0.96 μg/L and 2.16 ± 0.17 mmol/L respectively) were significantly lower than those in controls (3.9 ± 1.48 μg/L and 2.31 ± 0.21 mmol/L respectively, both P<0.01). TC and LDL levels in the subclinical hypothyroid subjects (5.58 ± 0.41 mmol/L and 3.67 ± 0.36 mmol/L) were significantly higher than those in controls (P<0.01). Conclusion: The lowering of calcium levels in subjects with subclinical hypothyroidism would lead to loss of bone mass. Decreased S-BGP contents might be the chief cause of osteoporosis in these subjects. (authors)

To investigate the correlation between glucose concentrations in serum, plasma, and whole blood measured by a point-of-care glucometer (POCG) and serum glucose concentration measured by a biochemical analyzer. Prospective clinical study. 96 blood samples from 80 dogs and 90 blood samples from 65 cats. Serum, plasma, and whole blood were obtained from each blood sample. The glucose concentrations in serum, plasma, and whole blood measured by a POCG were compared with the serum glucose concentration measured by a biochemical analyzer by use of the Lin concordance correlation coefficient (ρc) and Bland-Altman plots. For both canine and feline samples, glucose concentrations in serum and plasma measured by the POCG were more strongly correlated with the serum glucose concentration measured by the biochemical analyzer (ρc, 0.98 for both canine serum and plasma; ρc, 0.99 for both feline serum and plasma) than was that in whole blood (ρc, 0.62 for canine samples; ρc, 0.90 for feline samples). The mean difference between the glucose concentrations determined by the biochemical analyzer and the POCG in serum, plasma, and whole blood was 0.4, 0.3, and 31 mg/dL, respectively, for canine samples and 7, 6, and 32 mg/dL, respectively, for feline samples. Results indicated that use of a POCG to measure glucose concentrations in serum or plasma may increase the accuracy and reliability of diagnostic and treatment decisions associated with glucose homeostasis disorders in dogs and cats.

Aberrant Hedgehog ligands induce progressive pancreatic fibrosis by paracrine activation of myofibroblasts and ductular cells in transgenic zebrafish.

Directory of Open Access Journals (Sweden)

In Hye Jung

Full Text Available Hedgehog (Hh signaling is frequently up-regulated in fibrogenic pancreatic diseases including chronic pancreatitis and pancreatic cancer. Although recent series suggest exclusive paracrine activation of stromal cells by Hh ligands from epithelial components, debates still exist on how Hh signaling works in pathologic conditions. To explore how Hh signaling affects the pancreas, we investigated transgenic phenotypes in zebrafish that over-express either Indian Hh or Sonic Hh along with green fluorescence protein (GFP to enable real-time observation, or GFP alone as control, at the ptf1a domain. Transgenic embryos and zebrafish were serially followed for transgenic phenotypes, and investigated using quantitative reverse transcription-polymerase chain reaction (qRT-PCR, in situ hybridization, and immunohistochemistry. Over-expression of Ihh or Shh reveals virtually identical phenotypes. Hh induces morphologic changes in a developing pancreas without derangement in acinar differentiation. In older zebrafish, Hh induces progressive pancreatic fibrosis intermingled with proliferating ductular structures, which is accompanied by the destruction of the acinar structures. Both myofibroblasts and ductular are activated and proliferated by paracrine Hh signaling, showing restricted expression of Hh downstream components including Patched1 (Ptc1, Smoothened (Smo, and Gli1/2 in those Hh-responsive cells. Hh ligands induce matrix metalloproteinases (MMPs, especially MMP9 in all Hh-responsive cells, and transform growth factor-ß1 (TGFß1 only in ductular cells. Aberrant Hh over-expression, however, does not induce pancreatic tumors. On treatment with inhibitors, embryonic phenotypes are reversed by either cyclopamine or Hedgehog Primary Inhibitor-4 (HPI-4. Pancreatic fibrosis is only prevented by HPI-4. Our study provides strong evidence of Hh signaling which induces pancreatic fibrosis through paracrine activation of Hh-responsive cells in vivo.

Full Text Available In northern Brazil, the seasons are not well defined compared to the South and Southeast regions, due to a hot and humid equatorial climate with a rainy season, known as the Amazonian winter, and a period with less rain, known as the Amazonian summer. The goal of this study was to evaluate the biochemical variation of serum from the Amazon Boa constrictor by correlating the values with the seasons of the region. A biochemical analysis of the serum was performed (AST, ALT, LDH, ALP, calcium, uric acid, phosphorus, total protein, albumin and globulin using 31 individuals of Boa constrictor constrictor, which were kept in captivity. It was observed that eight of the ten parameters were higher in the winter compared to the summer (total protein, albumin, globulin, ALT, AST, ALP, LDH and calcium. The ALT, AST and calcium values had statistically significant differences for the summer and winter, while the other parameters appear to be influenced by seasonality. This was the first study of snakes kept in captivity that analyzed the serum chemistry profile of Boa constrictor constrictor from the state of Pará, Brazil.

2009-01-01

The serum volumes of the blood samples are varied from one patient to another according to the packed cell volume (PCV %), so if the patient sample has low PCV %, it will have high serum volume and vice versa. To calculate a certain clinical parameter such as glucose in the serum of patients using the conventional calculation, it will give the concentration in units per deci liter serum, while by calculating the concentration according to the ratio of serum volume to the total volume of the blood, it will give different results. Thus, the present study aimed to find a new theory used for calculation of some biochemical parameters concentration taking into consideration the ratio of plasma volume to the total blood volume. The present study was conducted on 122 subjects. These subjects were categorized into 4 groups. Group 1 (G1) comprised 40 healthy subjects as control group, group 2 (G2) comprised 30 low PCV % patients, group 3 (G3) comprised 30 subjects with relatively high PCV % and group 4 comprised 22 diabetic patients. Each group of the previous groups was further subdivided into group a (G a ) and group b (G b ). In the later group, the results were multiplied by the correction factor (V p /V b ), which is the ratio of plasma volume (V p ) to the blood volume (V b ) TSH hormone, glucose, cholesterol, triglycerides, urea, creatinine, uric acid, alanine aminotransferase (ALT), aspartate transaminase (AST) and alkaline phosphatase (ALP) were estimated and the results were multiplied by the correction factor (V p /V b ) to get the results after correction. Compared the results before and after correction, there was a very highly significant (ρ p /V b ), thus we recommended that biochemical parameters results must be calculated as indicated in the present study to obtain actual results which might be useful in the correct diagnosis, monitoring and follow up of the different diseases

Increasing evidence suggests that Mediterranean Diet (MD) is correlated with reduced risk of breast cancer (BC) and cancer mortality, since it modifies patients' serum antioxidant capacity, body composition and biochemical parameters. The aim of the study was to investigate whether a dietary intervention based on MD has a beneficial effect on these factors. In this intervention study, seventy female BC survivors were randomly assigned to (1) the intervention group (personalized dietary intervention based on MD) and (2) the control group (received the updated American Cancer Society Guidelines on Nutrition and Physical Activity for Cancer Prevention and ad libitum diet). Both groups were assessed twice [beginning, end of study (after 6 months)] regarding their anthropometric and biochemical parameters, serum vitamin C, vitamin A, a-tocopherol and CoQ10 levels, dietary intake and adherence to MD. An additional intermediate analysis was conducted on participants' body composition and biochemical profile. Concerning the intervention group, body weight, body fat mass, waist circumference, body mass index as well as HDL-cholesterol were significantly decreased (P body weight, body fat mass and serum total cholesterol rose (P body composition, adherence to MD and glycemic profile of postmenopausal BC survivors.

In this study, blood serum trace elements, biochemical and hematological parameters were obtained to assess the health status of an elderly population residing in Sao Paulo city, SP, Brazil. Results obtained showed that more than 93% of the studied individuals presented most of the serum trace element concentrations and of the hematological and biochemical data within the reference values used in clinical laboratories. However, the percentage of elderly presenting recommended low density lipoprotein (LDL) cholesterol concentrations was low (70%). The study indicated positive correlation between the concentrations of Zn and LDL-cholesterol (p<0.06). (author)

Full Text Available Clot activator serum tubes have significantly improved turnaround times for result reporting compared to plain tubes. With increasing workload and service performance expectations confronting clinical laboratories with high-volume testing and with particular emphasis on critical analytes, attention has focussed on preanalytical variables that can be improved. We carried out a field study on the test performance of BD vacutainer rapid serum tubes (RSTs compared to current institutional issued BD vacutainer serum separator tubes (SSTs in its test result comparability, clotting time, and stability on serum storage. Data from the study population (n=160 of patients attending outpatient clinics and healthy subjects showed that results for renal, liver, lipids, cardiac, thyroid, and prostate biochemical markers were comparable between RSTs and SSTs. Clotting times of the RSTs were verified to be quick with a median time of 2.05 min. Analyte stability on serum storage at 4°C showed no statistically significant deterioration except for bicarbonate, electrolytes, and albumin over a period of 4 days. In conclusion, RSTs offered savings in the time required for the clotting process of serum specimens. This should translate to further trimming of the whole process from blood collection to result reporting without too much sacrifice on test accuracy and performance compared to the current widely used SSTs in most clinical laboratories.

Full Text Available Objective: To analyze the evaluation value of coronary CT angiography for coronary plaque features and its correlation with platelet function and serum biochemical indexes. Methods: A total of 450 patients with coronary heart disease were divided into calcified plaque group (CT value≥130HU (n=117, soft plaque group (CT value≤60HU (n=150 and mixed plaque group (CT value 60-130HU (n=183 by coronary CT angiography (CTA, and 100 healthy subjects who received physical examination in our hospital during the same period were selected as control group. Differences in platelet function and serum biochemical indexes were compared among four groups of patients, and the judgment value of atheromatous plaque CT value from CTA for the severity of coronary heart disease was analyzed. Results: Platelet function parameters MPV, TEG-MA, P-selectin, PDGF-BB and vWF levels in peripheral blood of soft plaque group were higher than those of the other three groups; inflammatory factors CRP, IL-6, IL-12, IL-18 and IL-23 content in serum were higher than those of the other three groups; chemokines MCP-1, CXCL16, Fractalkine and RANTES content in serum were higher than those of the other three groups; adipocytokines Leptin and RBP4 content in serum were higher than those of the other three groups while SFRP5 content was lower than those of the other three groups. Atheromatous plaque CT value in patients with coronary heart disease was directly correlated with platelet function and the content of serum biochemical indexes. Conclusions: Coronary CTA can accurately assess coronary atheromatous plaque features, and can also be a reliable noninvasive method to judge coronary heart disease severity, treatment prognosis and so on.

Full Text Available Background: Zinc is an important cause of morbidity, particularly among young children. The dietary, functional, and biochemical indicators should be used to assess zinc status and to indicate the need for zinc interventions. Objective: The purpose of this study was to determine the zinc status and reference intervals for serum zinc concentration considering dietary, functional, and biochemical indicators in apparently healthy children in the Northeast Region of Brazil. Design: The cross-sectional study included 131 healthy children: 72 girls and 59 boys, aged between 6 and 9 years. Anthropometric assessment was made by body mass index (BMI and age; dietary assessment by prospective 3-day food register, and an evaluation of total proteins was performed. Zinc in the serum samples was analyzed in triplicate in the same assay flame, using atomic absorption spectrophotometry. Results: With respect to dietary assessment, only the intake of fiber and calcium was below the recommendations by age and gender. All subjects were eutrophic according to BMI and age classification. Zinc intake correlated with energy (p=0.0019, protein (p=0.0054, fat (p<0.0001, carbohydrate (p=0.0305, fiber (p=0.0465, calcium (p=0.0006, and iron (p=0.0003 intakes. Serum zinc correlated with protein intake (p=0.0145 and serum albumin (p=0.0141, globulin (p=0.0041, and albumin/globulin ratio (p=0.0043. Biochemical parameters were all within the normal reference range. Reference intervals for basal serum zinc concentration were 0.70–1.14 µg/mL in boys, 0.73–1.17 µg/mL in girls, and 0.72–1.15 µg/mL in the total population. Conclusions: This study presents pediatric reference intervals for serum zinc concentration, considering dietary, functional, and biochemical indicators, which are useful to establish the zinc status in specific groups. In this regard, there are few studies in the literature conducted under these conditions, which make it an innovative methodology.

To investigate the negative interference of ascorbic acid in serum biochemical tests in relation to the dose of vitamin C intake and to the time of blood collection. Healthy volunteers (n = 18) consumed daily doses of vitamin C (0.25-4.0 g) for 1 week and serum parameters were assayed prior to the experiment and on the eighth day of consumption. Blood samples were collected 4, 12 and 24 h after vitamin C intake. Serum levels of ascorbic acid increased significantly after vitamin C ingestion inhibiting urate and total bilirubin tests 4 and 12 h after intake (P cholesterol tests. Addition of ascorbic acid to serum inhibited the urate test to a similar extent to that observed after vitamin C intake. However, after ingesting vitamin C, the interference for the bilirubin test was greater than that of the in vitro interference. Commonly taken doses of supplementary vitamin C interfered negatively with the serum urate test based on the Trinder method, and with bilirubin metabolism.

Ductular reactions (DRs) are observed in virtually all forms of human liver disease; however, the histogenesis and function of DRs in liver injury are not entirely understood. It is widely believed that DRs contain bipotential liver progenitor cells (LPCs) that serve as an emergency cell pool to regenerate both cholangiocytes and hepatocytes and may eventually give rise to hepatocellular carcinoma (HCC). Here, we used a murine model that allows highly efficient and specific lineage labeling of the biliary compartment to analyze the histogenesis of DRs and their potential contribution to liver regeneration and carcinogenesis. In multiple experimental and genetic liver injury models, biliary cells were the predominant precursors of DRs but lacked substantial capacity to produce new hepatocytes, even when liver injuries were prolonged up to 12 months. Genetic modulation of NOTCH and/or WNT/β-catenin signaling within lineage-tagged DRs impaired DR expansion but failed to redirect DRs from biliary differentiation toward the hepatocyte lineage. Further, lineage-labeled DRs did not produce tumors in genetic and chemical HCC mouse models. In summary, we found no evidence in our system to support mouse biliary-derived DRs as an LPC pool to replenish hepatocytes in a quantitatively relevant way in injury or evidence that DRs give rise to HCCs.

Materials and Methods: A prospective study in 49 newly diagnosed (as per Rotterdam criteria Indian PCOS women was conducted. PCOS women were clinically examined and investigated for biochemical parameters. Results : The mean serum adiponectin was 12 ± 9.4 μg/mL (range 0.47-45. Hypoadiponectinemia (serum adiponectin <4 μg/mL was present in 22% patients. Age and adiponectin correlated significantly and inversely (r = −0.42, P = 0.027. Overweight/obese patients had lower mean adiponectin levels than normal weight (11.62 ± 9.5 vs 13.58 ± 9.5, P = 0.56. It was significantly lower in patients with acanthosis nigricans (AN as compared with those without AN (8.4 ± 5.9 vs 15 ± 11, P = 0.038. Hirsute patients showed lower mean adiponectin levels than nonhirsute (10 ± 7.3 vs 13 ± 10, P = 0.57. A positive, insignificant correlation was observed between serum adiponectin and cholesterol, low-density lipoprotein, follicle stimulating hormone (FSH, thyroid stimulating hormone, levels. A negative insignificant correlation existed between serum adiponectin and luteinizing hormone (LH, LH: FSH ratio, prolactin, dehydroepiandrosterone, testosterone, triglyceride, high-density lipoprotein, fasting blood glucose, fasting insulin, and Homeostasis Model Assessment. Conclusion: Hypoadiponectinemia is present in one-fifth of women with PCOS. Adiponectin levels decrease as age advances. Low levels of adiponectin possibly contributes to the development of dermal manifestation (AN of insulin resistance.

Full Text Available Clinical pathology testing of rodents is often challenging due to insufficient sample volume. One solution in clinical veterinary and exploratory research environments is dilution of samples prior to analysis. However, published information on the impact of preanalytical sample dilution on rodent biochemical data is incomplete. The objective of this study was to evaluate the effects of preanalytical sample dilution on biochemical analysis of mouse and rat serum samples utilizing the Siemens Dimension Xpand Plus. Rats were obtained from end of study research projects. Mice were obtained from sentinel testing programs. For both, whole blood was collected via terminal cardiocentesis into empty tubes and serum was harvested. Biochemical parameters were measured on fresh and thawed frozen samples run straight and at dilution factors 2–10. Dilutions were performed manually, utilizing either ultrapure water or enzyme diluent per manufacturer recommendations. All diluted samples were generated directly from the undiluted sample. Preanalytical dilution caused clinically unacceptable bias in most analytes at dilution factors four and above. Dilution-induced bias in total calcium, creatinine, total bilirubin, and uric acid was considered unacceptable with any degree of dilution, based on the more conservative of two definitions of acceptability. Dilution often caused electrolyte values to fall below assay range precluding evaluation of bias. Dilution-induced bias occurred in most biochemical parameters to varying degrees and may render dilution unacceptable in the exploratory research and clinical veterinary environments. Additionally, differences between results obtained at different dilution factors may confound statistical comparisons in research settings. Comparison of data obtained at a single dilution factor is highly recommended.

Full Text Available Bacground/Aim. Preterm delivery is one of the most common complications in pregnancy, and it is the major cause (75- 80% of all neonatal deaths. Bacterial vaginosis predisposes to an increased risk of preterm delivery, premature rupture of membrane and miscarriage. In this syndrome normal vaginal lactobacilli, which produce protective H2O2, are reduced and replaced with anaerobic, gram-negative bacteria and others. The aim of this study was to evaluate the influence of bacterial vaginosis on the week of delivery and biochemical markers of inflammation in the serum. Methods. A total of 186 pregnant women were included into this study, between the week 16 and 19 of pregnancy. In the study group there were 76 pregnant women with diagnosed bacterial vaginosis by the criteria based on vaginal Gram-stain Nugent score and Amsel criteria. In the control group there were 110 healthy women with normal vaginal flora. Ultrasound examination was performed in both groups. Vaginal fluid and blood samples were taken to determine biochemical markers with colorimetric methods. Results. The week of delivery was statistically significantly shorter in the study group and the levels of biochemical markers of inflammation (C-reactive protein and fibrinogen in the serum were statistically significantly higher in women with bacterial vaginosis comparing to the control group. Also the levels of uric acid and white blood cells in the serum were higher in the study group compared to the control one. Conclusion. Our study indicates that the pregnancy complicated with bacterial vaginosis ends much earlier than the pregnancy without it. Also, higher levels of biochemical markers of inflammation in the serum in the study group, similarly to results of other studies, suggest that pathophysiological processes responsible for preterm delivery can begin very early in pregnancy.

LFN Silva

Full Text Available Similarly to other reptiles, snakes are ectothermic animals and depend exclusively on the environment for the maintenance of their physiological, biochemical and immunological processes. Thus, changes in biochemical values can be expected due to seasonal influence. Twenty-two adult specimens of Boa constrictor amarali kept in captivity were used. Blood collections were done in two different seasons: winter (July 2004 and summer (January 2005 for the following assays: uric acid, aspartate aminotransferase (AST, glucose, cholesterol, total protein, and serum protein electrophoresis. The mean biochemical results found in summer and winter, respectively, were: 6.3 ± 3.4 and 11.3 ± 6.2 mg/dL for uric acid; 28.7 ± 12.4 and 20.7 ± 16.2 UI/L for AST; 26.3 ± 17 and 17.4 ± 6.8 mg/dL for glucose; 67.3 ± 30.2 and 69.7 ± 38.5 mg/dL for cholesterol; and 5.9 ± 1.6 and 5.9 ± 1.4 g/dL for total protein. Results regarding electrophoresis in summer and winter, respectively, were: 1.9 ± 0.7 and 2.4 ± 0.6 g/dL for albumin; 0.7 ± 0.2 and 0.5 ± 0.2 g/dL for α-globulin; 1.5 ± 0.5 and 1.7 ± 0.6 g/dL for β-globulin; and 1.8 ± 0.5 and 1.5 ± 0.5 g/dL for g-globulin. In the summer, there was a significant increase in AST and a decrease in uric acid (p < 0.05. Serum protein electrophoresis showed a significant increase in α-globulin fraction (p < 0.05 in the same season. There were not significant differences between seasons for the remaining variables. Based on these results, the period of the year must be considered in the interpretation of some biochemical values for these animals.

Notch signaling and progenitor/ductular reaction in steatohepatitis.

Directory of Open Access Journals (Sweden)

Carola M Morell

Full Text Available Persistent hepatic progenitor cells (HPC activation resulting in ductular reaction (DR is responsible for pathologic liver repair in cholangiopathies. Also, HPC/DR expansion correlates with fibrosis in several chronic liver diseases, including steatohepatitis. Increasing evidence indicates Notch signaling as a key regulator of HPC/DR response in biliary and more in general liver injuries. Therefore, we aimed to investigate the role of Notch during HPC/DR activation in a mouse model of steatohepatitis.Steatohepatitis was generated using methionine-choline deficient (MCD diet. For hepatocyte lineage tracing, R26R-YFP mice were infected with AAV8-TBG-Cre.MCD diet promoted a strong HPC/DR response that progressively diffused in the lobule, and correlated with increased fibrosis and TGF-β1 expression. Notch signaling was unchanged in laser-capture microdissected HPC/DR, whereas Notch receptors were down regulated in hepatocytes. However, in-vivo lineage tracing experiments identified discrete hepatocytes showing Notch-1 activation and expressing (the Notch-dependent Sox9. Stimulation of AML-12 hepatocyte-cell line with immobilized Jag1 induced Sox9 and down-regulated albumin and BSEP expression. TGF-β1 treatment in primary hepatic stellate cells (HSC induced Jag1 expression. In MCD diet-fed mice, αSMA-positive HSC were localized around Sox9 expressing hepatocytes, suggesting that Notch activation in hepatocytes was promoted by TGF-β1 stimulated HSC. In-vivo Notch inhibition reduced HPC response and fibrosis progression.Our data suggest that Notch signaling is an important regulator of DR and that in steatohepatitis, hepatocytes exposed to Jag1-positive HSC, contribute to pathologic DR by undergoing Notch-mediated differentiation towards an HPC-like phenotype. Given the roles of Notch in fibrosis and liver cancer, these data suggest mesenchymal expression of Jag1 as an alternative therapeutic target.

The role of ductular reaction (DR) in hepatocellular carcinoma (HCC) remains to be elucidated. In this study, we tried to uncover possible effect by correlating peritumoral DR in a necroinflammatory microenvironment with postoperative prognosis in HCC. The expression of peritumoral DR/CK19 by immunohistochemistry, necroinflammation and fibrosis were assessed from 106 patients receiving curative resection for HCC. Prognostic values for these and other clinicopathologic factors were evaluated. Peritumoral DR significantly correlated with necroinflammation (r = 0.563, p = 3.4E-10), fibrosis (r = 0.435, p = 3.1E-06), AFP level (p = 0.010), HBsAg (p = 4.9E-4), BCLC stage (p = 0.003), TNM stage (p = 0.002), multiple nodules (p = 0.004), absence of tumor capsule (p = 0.027), severe microscopic vascular invasion (p = 0.031) and early recurrence (p = 0.010). Increased DR was significantly associated with decreased RFS/OS (p = 4.8E-04 and p = 2.6E-05, respectively) in univariate analysis and were identified as an independent prognostic factor (HR = 2.380, 95% CI = 1.250-4.534, p = 0.008 for RFS; HR = 4.294, 95% CI = 2.255-8.177, p = 9.3E-6 for OS) in multivariate analysis. These results suggested that peritumoral DR in a necroinflammatory microenvironment was a poor prognostic factor for HCC after resection

The effects were studied of intravenous and intramuscular administration of radioprotectives cystamine and gammaphos in dogs on the biochemical parameters of the blood serum. The activities were studied of enzymes aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, creatinine kinase, gamma-glutamyl transpeptidase, lactate dehydrogenase, malate dehydrogenase, sorbitol dehydrogenase and alpha-amylase. The contents were determined of total protein, albumin, bilirubin, urea nitrogen, creatinine, glucose, triglycerides, cholesterol, lipids, calcium, sodium and potassium. Cystamine was shown to be hepatotoxic. The intramuscular administration of gammaphos was found to be more advantageous than of cystamine. Only slight increase was observed in the activities of lactate dehydrogenase, malate dehydrogenase, and alpha-amylase. With cystamine, the changes in all biochemical parameters were most marked.

Full Text Available The target of this study is to determine the interrelation among serum Li level on bone metabolism (Ca, P, Parathormon, and Vitamin-D, sex and metabolic hormones (estrogen, FSH, LH and TSH, and some biochemical parameters in premenopausal and postmenopausal women. The study is carried out with 10 women: 5 premenopausal and 5 postmenopausal women. The serum Li levels, bone metabolism indicators (i.e., ALP, Ca, P, Mg, Cu, Zn and some biochemical parameters such as serum tryglyceride, alkalene phosphatase, total cholesterol, HDL, LDL and cholesterol levels were determined. The estrogen blood level of women in menopause period was found to be lower than that of women in pre-menopause period (p<0.01 and the FSH level was found to be higher (p<0.01. In the lipid profile the triglyceride level in the post-menopause period was found to be low (p<0.05 and HDL (p<0.001, LDL (p<0.001 and the cholesterol levels were found to be high (p<0.001. The alkalene phosphatase (p<0.001 and Vitamin-D levels (p<0.001 were found to decrease. When the mineral levels were investigated no meaningful difference was observed in the serum magnesium and copper levels while zinc (p<0.01 and phosphorus (p<0.005 levels were observed to increase, the calcium levels (p<0.05 decreased and Li levels considerably decreased (p<0.0001. According to the results obtained it was determined for the first time that Li defficiency can be related with menopause and the related diseases and thus Li therapy can be used in developing new treatment protocols of menopause as an alternative method.

Full Text Available Background: The aim of this study was to evaluate the functional capacity of the liver based on the activity of specific enzymes and bilirubin in serum and also to investigate the influence of mechanical and toxic effects of Fasciola hepatica on the structures of the blood vessels and biliary tract in the sheep liver.Methods: Blood samples and liver of 63 indigenous sheep of Pramenka breed, slaughtered in the period from March to December 2009 were used. Based on parasitological findings in the liver, all animals were divided into two groups: control (n=34 and infected group (n=29. For investigation and description of pathological changes in sheep liver, naturally infected with F. hepatica, corrosion cast technique was used.Results: Biochemical analysis of tested parameters showed a significant elevation (P≤0.05 of serum gamma-glutamyl transferase (GGT, total bilirubin (TBIL and direct bilirubin (DBIL in infected sheep group comparing with the control group. No significant differences were observed for activity of aspartate aminotranferase (AST between groups. Vascular and biliary systems of the liver were found to be affected.Conclusion: Results of biochemical analysis are consistent with pathological findings and measuring of tested parameters could be used in early diagnosis of sheep fasciolosis and to test the effectiveness of anthelmintic therapy. Corrosion cast technique is very useful for investigation of pathological changes and neoangiogenesis of vascular and biliary system in sheep liver, caused by mechanical and toxic effects of F. hepatica.

Determining perturbed biochemical functions associated with tobacco smoking should be helpful for establishing causal relationships between exposure and adverse events. A multiplatform comparison of serum of smokers (n = 55) and never-smokers (n = 57) using nuclear magnetic resonance spectroscopy, UPLC-MS and statistical modeling revealed clustering of the classes, distinguished by metabolic biomarkers. The identified metabolites were subjected to metabolic pathway enrichment, modeling adverse biological events using available databases. Perturbation of metabolites involved in chronic obstructive pulmonary disease, cardiovascular diseases and cancer were identified and discussed. Combining multiplatform metabolic phenotyping with knowledge-based mapping gives mechanistic insights into disease development, which can be applied to next-generation tobacco and nicotine products for comparative risk assessment.

Sublethal microcystin exposure and biochemical outcomes among hemodialysis patients.

Directory of Open Access Journals (Sweden)

Elizabeth D Hilborn

Full Text Available Cyanobacteria are commonly-occurring contaminants of surface waters worldwide. Microcystins, potent hepatotoxins, are among the best characterized cyanotoxins. During November, 2001, a group of 44 hemodialysis patients were exposed to microcystins via contaminated dialysate. Serum microcystin concentrations were quantified with enzyme-linked immunosorbent assay which measures free serum microcystin LR equivalents (ME. We describe serum ME concentrations and biochemical outcomes among a subset of patients during 8 weeks following exposure. Thirteen patients were included; 6 were males, patients' median age was 45 years (range 16-80, one was seropositive for hepatitis B surface antigen. The median serum ME concentration was 0.33 ng/mL (range: <0.16-0.96. One hundred thirty nine blood samples were collected following exposure. Patients' biochemical outcomes varied, but overall indicated a mixed liver injury. Linear regression evaluated each patient's weekly mean biochemical outcome with their maximum serum ME concentration; a measure of the extrinsic pathway of clotting function, prothrombin time, was negatively and significantly associated with serum ME concentrations. This group of exposed patients' biochemical outcomes display evidence of a mixed liver injury temporally associated with microcystin exposure. Interpretation of biochemical outcomes are complicated by the study population's underlying chronic disease status. It is clear that dialysis patients are a distinct 'at risk' group for cyanotoxin exposures due to direct intravenous exposure to dialysate prepared from surface drinking water supplies. Careful monitoring and treatment of water supplies used to prepare dialysate is required to prevent future cyanotoxin exposure events.

An increase of the serum PSA-level is a sensitive in vitro marker for recurrent prostate cancer. However, it remains difficult to differentiate between local, regional or distant recurrent disease. The aim of this study was to assess the relationship between the detection rate of [ 11 C]Choline-PET/CT and the serum PSA-level in patients with a biochemical recurrence of prostate cancer with the view towards localisation of recurrent disease. Sixty-three patients (mean age, 68.8 ± 6.9; range, 45-83 years) with biochemical recurrence after primary therapy for prostate cancer were included in the analysis. Mean PSA-levels were 5.9 ± 9.7 ng/ml (range, 0.2-39 ng/ml; median, 2.15). Of the 63 patients, 17 were under anti-androgen therapy at the time of [ 11 C]Choline PET/CT. Patients underwent a [ 11 C]Choline-PET/CT study after injection of 656 ± 119 MBq [ 11 C]Choline on a Sensation 16 Biograph PET/CT scanner. Of the 63 patients, 35 (56%) showed a pathological [ 11 C]Choline uptake. The detection rate of [ 11 C]Choline-PET/CT showed a relationship with the serum PSA-level: The detection rate was 36% for a PSA-value 11 C]Choline-PET/CT (p = 0.374). As an important result our study shows that even for PSA-values 11 C]Choline-PET/CT is 36%. Furthermore, the detection rate of [ 11 C]Choline-PET/CT shows a positive relationship with serum PSA-levels in patients with biochemical recurrence of prostate cancer after primary therapy. Therefore, in these patients, [ 11 C]Choline PET/CT allows not only to diagnose but also to localise recurrent disease with implications on disease management (localised vs systemic therapy).

Full Text Available Several studies have revealed that the preoperative serum testosterone and percent tumor volume (PTV predict extra-prostatic extension (EPE and biochemical recurrence (BCR after radical prostatectomy. This study investigated the prognostic significance of serum testosterone and PTV in relation to EPE and BCR after laparoscopic radical prostatectomy (LRP. We reviewed 520 patients who underwent LRP between 2004 and 2012. PTV was determined as the sum of all visually estimated tumor foci in every section. BCR was defined as two consecutive increases in the postoperative prostate-specific antigen (PSA >0.2 ng ml−1 . The threshold for serum total testosterone was 3.0 ng ml−1 . Multivariate logistic regression was used to define the effect of variables on the risk of EPE and BCR. A low serum testosterone (<3.0 ng ml−1 was associated with a high serum PSA, Gleason score, positive core percentage of the prostate biopsy, PTV, and all pathological variables. On multivariate analysis, similar to previous studies, the serum PSA, biopsy positive core percentage, Gleason score, and pathological variables predicted EPE and BCR. In addition, low serum testosterone (<3.0 ng ml−1 , adjusted OR, 8.52; 95% CI, 5.04-14.4, P= 0.001 predicted EPE and PTV (adjusted OR, 1.02; 95% CI, 1.01-1.05, P= 0.046 predicted BCR. In addition to previous predictors of EPE and BCR, low serum testosterone and PTV are valuable predictors of EPE and BCR after LRP.

Full Text Available Cholangiopathy is a chronic immune-mediated disease of the liver, which is characterized by cholangitis, ductular reaction and biliary-type hepatic fibrosis. There is no proven medical therapy that changes the course of the disease. In previous studies, melittin was known for attenuation of hepatic injury, inflammation and hepatic fibrosis. This study investigated whether melittin provides inhibition on cholangitis and biliary fibrosis in vivo. Feeding 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC to mice is a well-established animal model to study cholangitis and biliary fibrosis. To investigate the effects of melittin on cholangiopathy, mice were fed with a 0.1% DDC-containing diet with or without melittin treatment for four weeks. Liver morphology, serum markers of liver injury, cholestasis markers for inflammation of liver, the degree of ductular reaction and the degree of liver fibrosis were compared between with or without melittin treatment DDC-fed mice. DDC feeding led to increased serum markers of hepatic injury, ductular reaction, induction of pro-inflammatory cytokines and biliary fibrosis. Interestingly, melittin treatment attenuated hepatic function markers, ductular reaction, the reactive phenotype of cholangiocytes and cholangitis and biliary fibrosis. Our data suggest that melittin treatment can be protective against chronic cholestatic disease in DDC-fed mice. Further studies on the anti-inflammatory capacity of melittin are warranted for targeted therapy in cholangiopathy.

Neospora caninum is an important cause of abortion in dairy cattle. The general health of affected cows has not been investigated before. Therefore, the main objective of this study was to identify possible relationships between certain metabolic diseases and selected serum biochemical parameters in seropositive dairy cows against N. caninum antibodies in different stages of lactation. The study was carried out using 72 N. caninum seropositive cows and 61 seronegative dairy cows (control). Serum from all cows was tested to determine their N. caninum status (seropositive vs seronegative) using commercially available indirect enzyme-linked immunosorbent assay test kit (iELISA). In addition, serum biochemical parameters including beta-hydroxybutyrate (BHB), glucose, creatinine, blood urea nitrogen, total protein, albumin, alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH) and gamma-glutamyltranspeptidase (GGT) were determined using routine laboratory methods. The stage of lactation was obtained at the time of sampling from farm records. Student independent t-test showed that there was a significant difference in the serum concentrations of BHB, AST, ALT, and LDH between seropositive and seronegative cows. There was no significant association between seropositivity and the stage of lactation. However, multivariable logistic regression analysis showed that there was a strong association between seropositivity and BHB concentrations. Results of this study indicate a possible relationship between N. caninum seropositivity and certain metabolic diseases such as ketosis and fatty liver syndrome in dairy cows.

Determination of skeletal maturation and remaining growth potential is an essential part of treatment planning in orthodontics. The aim of our study was to determine the relationship between IGF-1 levels, IGFBP-3 levels with CVM staging to track the pre pubertal and pubertal growth spurts in female patients in North Indian population. This cross-sectional study was conducted on ninety female subjects in the age group of 8-20 years. Blood samples were collected and centrifuged and serum samples were then analysed by Human IGF-1 and IGFBP-3 enzyme-linked immunosorbent assay kits, specific for IGF-1 and IGFBP-3, respectively. CVM staging on lateral cephalometric radiograph was determined for all patients. Analysis of variance test followed by a post hoc test was used to compare mean IGF-1 and IGFBP-3 corresponding to six stages of cervical vertebrae maturation stages. Linear Pearson's correlations were performed to determine the trends of IGF-1, IGFBP-3, and its ratio relating to CVM stage. The kappa statistic was used to measure inter and intra examiner reliability. P value IGF-1 levels were found to be highest (403.3 ± 12.3 ng/ml) at CVMI3 stage of CVMI. The post-hoc test revealed a significant difference in IGF-1 levels between all stages of CVMI, thereby indicating a specific range of IGF-1 levels for a specific skeletal stage. Mean serum IGFBP-3 levels were found to be highest (5186.8 ± 1384.2 ng/ml) at CVMI4 stage of CVMI. The mean serum IGFBP-3 levels at CVMI4 were found to be significantly higher than the levels at all other CVMI stages except CVMI3 stage. IGF-1 and IGFBP-3 can serve as a potential biochemical indicator for assessment of skeletal maturity.

Full Text Available Aim: The study was undertaken to find out the effect of feeding cottonseed meal (CSM on performance of hematological and serum biochemical parameters in broiler birds. Materials and Methods: A 6-week biological trial was carried out with 432-day-old Cobb 400 broiler chicks distributed to nine experimental diets with six replicates, each containing eight chicks. The experimental diets were formulated based on total amino acids (BTAA or based on digestible amino acids (BDAA with or without iron supplementation with two levels of CSM (2% and 4% and control diet based on maize – soybean. The whole blood was subjected to hematological studies. The serum samples were analyzed for protein fractions and lipid profiles. Results: The packed cell volume (PCV value, red blood cell (RBC numbers, and hemoglobin (Hb were lower in iron unsupplemented CSM BTAA or BDAA diets than the control (33.86-35.54 vs. 36.41%, 2.78-2.87 vs. 2.98 × 106/μl, and 10.30-10.70 vs. 10.88%. Supplementation of iron in CSM diets improved the PCV, RBC numbers, and Hb, and the values were comparable to the control. White blood cell numbers, mean corpuscular volume, mean corpuscular Hb (MCH, and MCH concentration values were comparable to the control. The erythrocyte osmotic fragility (EOF was poor in birds fed diets containing up to 4% CSM BTAA or CSM BDAA without iron supplementation (32.02-32.57 vs. 28.77%. Supplementation of iron improved the EOF. The serum cholesterol level did not change with or without iron supplementation. Conclusion: This study suggested that feeding of CSM BTAA or BDAA up to 4% level voiding iron supplementation lowers the hematological parameters, whereas supplementation of iron did not alter serum protein fractions and cholesterol profile; however, it had lowered some hematological parameters, which was rectified by iron supplementation.

2014-08-01

Full Text Available A 42-day trial was undertaken to study the effect of different dietary levels of thyme essential oil (TEO on serum biochemical indices of broiler chickens. Seven hundred and sixty-eight selected one-day-old Mahua broilers were divided into 8 dietary treatment groups with an addition of 0.00, 0.05, 0.10, 0.15, 0.20, 0.25, 0.30 and 0.35 mg/kg of thyme essential oil respectively, with 4 replicate pens per treatment group (24 birds each. The feeding programme included a starter diet until day 21 and a finisher diet from day 22 until day 42. The results suggested that TEO markedly increased serum total proteins and globulins on day 21, significantly decreased alanine aminotransferase activity (P≤0.05, the albumin- to-globulin ratio, and serum urea on day 21 and 42, and in particular it improved highdensity lipoproteins on day 21 and 42 (P≤0.05. In conclusion, TEO can promote protein metabolism, enhance lipolysis and strengthen the immune function. Furthermore, after a comprehensive analysis, the ideal range of the essential oil addition to the broiler feed proved to be between 0.1 and 0.25 mg/kg.

Full Text Available Objective This study investigated the effect of fermented biogas residue (FBR of wheat on the performance, serum biochemical parameters, and meat quality in pigs. Methods We selected 128 pigs (the mean initial body weight was 40.24±3.08 kg and randomly allocated them to 4 groups (1 control group and 3 treatment groups with 4 replicates per group and 8 pigs per pen in a randomized complete block design based on initial body weight and sex. The control group received a corn-soybean meal-based diet, the treatment group fed diets containing 5%, 10%, and 15% FBR, respectively (abbreviated as FBR5, FBR10, and FBR15, respectively. Every group received equivalent-energy and nitrogen diets. The test lasted 60 days and was divided into early and late stages. Blood and carcass samples were obtained on 60 d. Meat quality was collected from two pigs per pen. Results During the late stage, the average daily feed intake and average daily gain of the treatment groups was greater than that of the control group (p<0.05. During the entire experiment, the average daily gain of the treatment groups was higher than that of the control group (p<0.05. Fermented biomass residue did not significantly affect serum biochemical parameters or meat quality, but did affect amino acid profiles in pork. The contents of Asp, Arg, Tyr, Phe, Leu, Thr, Ser, Lys, Pro, Ala, essential amino acids, non-essential amino acids, and total amino acids in pork of FBR5 and FBR10 were greater than those of the control group (p<0.05. Conclusion These combined results suggest that feeding FBR could increase the average daily gain and average daily feed intake in pigs and the content of several flavor-promoting amino acids.

Cilostazol is a phosphodiesterase III inhibitor increases adenosine 3', 5'-cyclic monophosphate (cyclic AMP) level which inhibits hepatic stellate cell activation. Its pharmacological effects include vasodilation, inhibition of vascular smooth muscle cell growth, inhibition of platelet activation and aggregation. The aim of the current study was to determine the effects of early administration of low dose cilostazol on cholestatic liver injury induced by common bile duct ligation (CBDL) in rat. Male Wistar rats (180-200g) were divided into three groups: Group A; simple laparotomy group (sham). Group B; CBDL, Group C; CBDL rats treated with cilostazol (9mg/kg daily for 21 days). Six rats from each group were killed by the end of weeks one and three after surgery, livers and serum were collected for biochemical and histopathological studies. Aspartate aminotransferase, alanine aminotransferase, gama glutamyl transferase, alkaline phosphatase and total bilirubin serum levels decreased in the cilostazol treated rats, when compared with CBDL rats. The hepatic levels of tumor necrosis factor-alpha, transforming growth factor-beta, and platelet derived growth factor-B were significantly lower in cilostazol treated rats than that in CBDL rats. Cilostazol decreased vascular endothelial growth factor level and hemoglobin content in the livers. Cilostazol significantly lowered portal pressure, inhibited ductular proliferation, portal inflammation, hepatic fibrosis and decreased hepatic hydroxyproline contents. Administration of cilostazol in CBDL rats improved hepatic functions, decreased ductular proliferation, ameliorated portal inflammation, lowered portal hypertension and reduced fibrosis. These effects of cilostazol may be useful in the attenuation of liver injury in cholestasis. Copyright © 2015 Elsevier B.V. All rights reserved.

Full Text Available Aim: The objective of this study was to evaluate the effect of feeding fermented fish silage (FFS on serum biochemical parameters of Japanese quails (Coturnix coturnix japonica. Materials and Methods: A total of 192, 7-day-old broiler Japanese quail chicks of either sex, were randomly distributed into four dietary treatments with four replicates in each group having 12 chicks in each replicate pen. The dietary treatments were T1 - Control diet, T2 - Diet containing 5% FFS, T3 - Diet containing 10% FFS, and T4 - Diet containing 15% FFS. Group body weight and feed consumption were recorded at weekly intervals. Feed conversion ratio (FCR was derived by dividing the feed consumed with the weekly body weight gain. At the end of the experiment, 8 birds from each treatment were selected randomly and sacrificed by cervical dislocation to study the carcass traits expressed as % pre-slaughter live weight. At 5 weeks of age, about 2 ml of blood was taken from the jugular vein of each selected bird, and serum samples were separated after centrifugation. Total protein, albumin/globulin (A/G ratio, calcium, phosphorus, triglyceride, total cholesterol, high density lipoprotein-cholesterol (HDL-C, very low density lipoprotein-cholesterol (VLDL-C, low density lipoprotein-cholesterol (LDL-C, alanine aminotransferase (ALT, and aspartate aminotransferase (AST were estimated in the serum. Results: The cumulative body weight gains from 1 to 5 weeks of age did not vary significantly between control and 5% FFS group. However, a linear decrease in body weight gain was observed by increasing the levels of FFS beyond 5% in the diet. The cumulative feed consumption was significantly higher in case of birds under control group during 1-5 weeks of age as compared to birds fed FFS based diet (5%, 10%, and 15%. No statistical difference in cumulative feed conversion ratio could be noticed during 1-5 weeks of age. The eviscerated yield decreased and giblet weight increased due

Fluoride is ubiquitously distributed in natural waters. Elevated fluoride may cause histopathological changes and induce oxidative stress in the gills of the common carp (Cyprinus carpio). The present study further evaluates the effects of fluoride on growth performance, body composition, and biochemical measurements of C. carpio. The results showed that food intake, growth, serum osmolality, body composition, and biochemical measures in the blood were affected by fluoride. Weight gain rate and specific growth rate in the exposed fish decreased compared with those of the control fish. Levels of crude protein and crude lipids were reduced in the fluoride-exposed fish. The major ion levels in the sera of fluoride-exposed fish were severely disturbed, resulting in a lower osmolality. All the biochemical parameters measured in the blood were affected by the exposure to fluoride. Total protein, albumin, globulin, and glucose in fish exposed to 63.6 mg/L, 77.7 mg/L, and 124.4 mg/L were lower than those in the control fish. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were markedly increased in exposed fish compared with control. Taken together, the data showed that exposure to fluoride caused a suite of detrimental effects in C. carpio, which might lead to a decrease in growth and food utilization efficiency. The results of the present study indicated that high levels of fluoride could pose a threat to carp in the field. © 2013 SETAC.

The zinc ion is essential for the living organism. Many pathological conditions have been described as a consequence of zinc deficiency. As zinc constitutes less than 0.01 percent of the body weight, it conventionally belongs to the group of trace elements. The method of atomic absorption spectrophotometry is used to measure the concentration of zinc in serum and urine from healthy persons. The assumptions of the method is discussed. The importance of protein binding, diet and the diurnal variation of serum zinc concentration is presented. Serum versus plasma zinc concentration is discussed. Reference serum zinc values from 104 normal subjects are given. Zinc in serum is almost entirely bound to proteins. A preliminary model for the estimation of the distribution of zinc between serum albumin and ..cap alpha../sub 2/-macroglobulin is set up. This estimate has been examined by an ultracentrufugation method. The binding of zinc to a ..cap alpha../sup 2/-macroglobulin in normal persons is appoximately 7 percent, in patients with cirrhosis of the liver of alcoholic origin approximately 6 percent, in patients with insulin dependent diabetes mellitus approximately 5 percent, and in patients with chronic renal failure approximately 2 percent. It is concluded, therefore, that for clinical purposes it is sufficient to use the concentration of total serum zinc corrected for the concentration of serum albumin.

Hepatic infarcts or abscesses occur after hepatic artery interruption. We explored the mechanisms of hepatic deprivation-induced acute liver injury and determine whether partial portal vein arterialization attenuated this injury in rats. Male Sprague-Dawley rats underwent either complete hepatic arterial deprivation or partial portal vein arterialization, or both. Hepatic ischemia was evaluated using biochemical analysis, light microscopy, and transmission electron microscopy. Hepatic ATP levels, the expression of hypoxia- and inflammation-associated genes and proteins, and the expression of bile transporter genes were assessed. Complete dearterialization of the liver induced acute liver injury, as evidenced by the histological changes, significantly increased serum biochemical markers, decreased ATP content, increased expression of hypoxia- and inflammation-associated genes and proteins, and decreased expression of bile transporter genes. These detrimental changes were extenuated but not fully reversed by partial portal vein arterialization, which also attenuated ductular reaction and fibrosis in completely dearterialized rat livers. Collectively, complete hepatic deprivation causes severe liver injury, including bile infarcts and biloma formation. Partial portal vein arterialization seems to protect against acute ischemia-hypoxia-induced liver injury.

The present study was conducted to evaluate the serum triglycerides, serum cholesterol, total protein, and IgG levels in elderly patients who were affected by periodontal disease. This study was conducted at the Rajah Muthiah Dental College and Hospital in the periodontics division. The study was conducted for a period of 3 months. This study is a prospective analytical study. Sixty individuals who were systemically healthy in the age group of 50 and above were included in this study. Control and experimental groups of 30 participants each were included. Plaque index, gingival index, probing pocket depth, and clinical attachment loss were recorded. Biochemical parameters such as serum cholesterol, serum triglycerides, total protein, and IgG levels were also evaluated and correlated with the periodontal parameters. Data was analyzed using SPSS version 16.0 (IBM Corp., Armonk, NY). The relationship between periodontal status and the biochemical parameters such as serum cholesterol, serum triglycerides, total protein, and IgG levels were evaluated by Student's t-test. There was no significant difference in the plaque and gingival scores between the experimental and control group. It was observed that serum cholesterol level and total protein level was lower in participants suffering from chronic periodontitis. Triglycerides level was significantly elevated in the experimental group. IgG, a level which is not significant, concluded that there is no difference in control and experimental group. It was concluded from the results obtained from the study that there is an association between serum triglycerides, serum cholesterol, total protein, and periodontal disease. However, further longitudinal and well-controlled studies are required to evaluate the relationship between these biochemical parameters and periodontal disease.

The study introduced anti-hyperglycemic influence of aqueous extract of Ocimum basilicum seeds (AEOBS) in Streptozotocin (STZ) induced diabetic rats and estimating its potential to ameliorate altered level of biochemical parameters, serum electrolytes level and haematological indices along with its effect on body weight of treated rats. The albino rats were selected to observe oral glucose tolerance test by oral intake of aq. glucose solution (4g/kg, body weight) in normal rats and estimation of blood glucose level after administration of AEOBS at 250mg/kg, 500mg/kg and standard drug glibenclamide at 0.6mg/kg, body weight. Antidiabetic activity was evaluated in chronic study models by STZ induced diabetes in rats followed by blood glucose estimation. Chronic study model was selected to carry out further studies to evaluate the effect of AEOBS at 250mg/kg, 500mg/kg and standard drug on body weight, alterations in biochemical parameters including AST, ALT, ALP, total bilirubin and total protein, alterations in serum electrolytes like Na + , K + , Cl - , HCO 3 - along with estimation of haematological indices like red blood cells (RBC), white blood cells (WBC), hemoglobin (Hb), lymphocytes, neutrophils, eosinophils, monocytes and basophils. AEOBS significantly reduced the blood glucose level of diabetic rats at both doses. Body weight was also improved significantly. Similarly, the levels of biochemical parameters, serum electrolytes, and haematological indices were significantly ameliorated at both doses of AEOBS. The histopathological results revealed reconstitution of pancreatic islets towards normal cellular architecture in rats treated with AEOBS. The results illustrated that AEOBS have eminent antidiabetic potential in STZ effectuated diabetes in rats and can be extensively used for the treatment of diabetes mellitus-II and its associated complications including anaemia, diabetic nephropathy, liver dysfunction, and immunosuppression.

This study evaluates serum creatine kinase isoenzyme activity in children with osteogenesis imperfecta to determine its usefulness as a biochemical marker during treatment with bisphosphonate. The changes of creatine kinase (CK) isoenzyme activity during and after discontinuation therapy were observed. These results could be useful in addressing over-treatment risk prevention. The brain isoenzyme of creatine kinase (CKbb) is highly expressed in mature osteoclasts during osteoclastogenesis, thus plays an important role in bone resorption. We previously identified high serum CKbb levels in 18 children with osteogenesis imperfect (OI) type 1 treated for 1 year with bisphosphonate (neridronate). In the present study, serum CK isoenzymes were evaluated in the same children with continuous versus discontinued neridronate treatment over a further 2-year follow-up period. This study included 18 children with OI type 1, 12 with continued (group A) and 6 with ceased (group B) neridronate treatment. Auxological data, serum biochemical markers of bone metabolism, bone mineral density z-score, and serum total CK and isoenzyme activities were determined in both groups. Serum CKbb was progressively and significantly increased in group A (p < 0.004) but rapidly decreased to undetectable levels in group B. In both groups, the cardiac muscle creatine kinase isoenzyme (CKmb) showed a marked decrease, while serum C-terminal telopeptide (CTx) levels were almost unchanged. This study provides evidence of the cumulative effect of neridronate administration in increasing serum CKbb levels and the reversible effect after its discontinuation. This approach could be employed for verifying the usefulness of serum CKbb as a biochemical marker in patients receiving prolonged bisphosphonate treatment. Moreover, the decreased serum CKmb levels suggest a systemic effect of these drugs.

Purpose: To review all the available radiotherapy (RT) literature on localized prostate cancer treatment where serum prostate-specific antigen (PSA) levels were used to both stratify patients and evaluate outcome and determine if any conclusions can be reached regarding an optimal radiotherapeutic management for this disease. Methods and Materials: A MEDLINE search was conducted to obtain all articles in English on prostate cancer treatment employing RT from 1986-1997. Studies were considered eligible for review only if they met all the following criteria: 1) pretreatment PSA values were recorded and grouped for subsequent evaluation, 2) posttreatment PSA values were continuously monitored, 3) definitions of biochemical control were stated, and 4) the median follow-up was given. Results: Of the 246 articles identified, only 20 met the inclusion criteria; 4 using conformal external beam RT, 8 using conventional external beam RT, and 8 using interstitial brachytherapy (4 using a permanent implant alone, 3 combining external beam RT with a permanent implant, and 1 combining a conformal temporary interstitial implant boost with external beam RT). No studies using neutrons (with or without external beam RT) or androgen deprivation (combined with external beam RT) were identified where patients were stratified by pretreatment PSA levels. Results for all therapies were extremely variable with the 3-5-year rates of biochemical control for patients with pretreatment PSA levels ≤4 ng/ml ranging from 48 to 100%, for PSA levels >4 and ≤10 ng/ml ranging from 44 to 90%, for PSA levels >10 and ≤20 ng/ml ranging from 27 to 89%, and for PSA levels >20 ranging from 14 to 89%. The median Gleason score, T-stage, definition of biochemical control, and follow-up were substantially different from series to series. No RT option consistently produced superior results. Conclusions: When data are reviewed from studies using serum PSA levels to stratify patients and to evaluate

Complete biochemical evaluation was performed by day 2 FSH, LH, serum prolactin, serum testosterone and fasting serum insulin determination. These results were recorded on the data collection form. Ultrasonic evaluation was performed with transvaginal ultrasound to check the morphological appearance of ovaries. A total of 508 patients were evaluated for epidemiological features of PCOS. Frequency of PCOS in the infertility clinic was 17.6% with high rate of obesity (68.5%) and hyperinsulinemia (59%). The highest rate of abnormal clinical, biochemical features were seen above BMI of 30. High rates of obesity, hyperinsulinemia and impaired glycemic control were seen in this series. It was demonstrated that high BMI had an association and correlation with abnormal clinical and biochemical features. Obese women with PCOS need more attention for their appropriate management.

Full Text Available In the present study, the age- and sex-specific changes of various haematological and blood serum biochemical blood parameters of Beluga (Huso huso were investigated. Blood samples were collected from 4-, 6-, 7-, and 8-year-old beluga (n = 7 for each sex and age. The specimens were fed at a rate of 0.5-3% body weight per day. AST and LDH levels in 7- and 8-year-old fish of both sexes were significantly higher (P<0.05 than those in 4- and 6-year-old individuals. The mean ALT were significantly different (P<0.05 in both sexes of 4-, 6-, and 7-year-old sturgeon. However, the 6-, 7-, and 8-year-old female sturgeon had higher ALP levels (P<0.05. Additionally, mean RBC, PCV, and Hb values were significantly higher (P<0.05 in 7- and 8-year-old females and males than the others. Two-tailed Pearson’s correlation between the biochemical and haematological parameters obtained for beluga sturgeon indicated significant positive correlations between AST and ALP, AST and LDH, ALP and LDH, RBC and Hb, RBC and PCV, Hb and PCV, MCH and MCHC, and MCV and MCH. However, significant negative correlations were found between RBC and MCV and MCH. These results suggest that the blood parameters of beluga are influenced by age- and sex-specific factors.

Aim: The present study was conducted to evaluate the serum triglycerides, serum cholesterol, total protein, and IgG levels in elderly patients who were affected by periodontal disease. Materials and Methods: This study was conducted at the Rajah Muthiah Dental College and Hospital in the periodontics division. The study was conducted for a period of 3 months. This study is a prospective analytical study. Sixty individuals who were systemically healthy in the age group of 50 and above were included in this study. Control and experimental groups of 30 participants each were included. Plaque index, gingival index, probing pocket depth, and clinical attachment loss were recorded. Biochemical parameters such as serum cholesterol, serum triglycerides, total protein, and IgG levels were also evaluated and correlated with the periodontal parameters. Data was analyzed using SPSS version 16.0 (IBM Corp., Armonk, NY). The relationship between periodontal status and the biochemical parameters such as serum cholesterol, serum triglycerides, total protein, and IgG levels were evaluated by Student's t-test. Results: There was no significant difference in the plaque and gingival scores between the experimental and control group. It was observed that serum cholesterol level and total protein level was lower in participants suffering from chronic periodontitis. Triglycerides level was significantly elevated in the experimental group. IgG, a level which is not significant, concluded that there is no difference in control and experimental group. Conclusion: It was concluded from the results obtained from the study that there is an association between serum triglycerides, serum cholesterol, total protein, and periodontal disease. However, further longitudinal and well-controlled studies are required to evaluate the relationship between these biochemical parameters and periodontal disease. PMID:28462181

Various studies on methylmercury (MeHg)-induced toxicity focused on the central nervous system (CNS) as a primary target. However, MeHg-mediated toxicity is related to metallic interaction with electrophilic groups, which are not solely restricted to the CNS, but these reactive groups are present ubiquitously in several systems/organs. The aim of this study was thus to examine MeHg-induced systemic toxicity in mice using a standardized neurotoxicology testing exposure model to measure cerebellar neurotoxicity by determining biochemical and behavioral parameters in the cerebellum. After 2 weeks exposure to MeHg (40 µg/ml; diluted in drinking water; ad libitum), adult male Swiss mice showed a marked motor impairment characteristic of cerebellar toxicity as noted in the following tests: rotarod, beam walking, pole, and hind limb clasping. MeHg treatment resulted in Hg deposition in the cerebellum as well as reduction in cerebellar weight, glutathione peroxidase (GPx) activity, and interleukin (IL)-6 levels. MeHg ingestion increased cerebellar glutathione reductase (GR) activity and brain-derived neurotrophic factor (BDNF) levels. In addition to cerebellar toxicity, MeHg treatment also elevated total and non-high density lipoprotein (non-HDL) cholesterol levels, as well as serum aspartate transaminase (AST) and alanine transaminase (ALT) enzymatic activities, systemic parameters. Increased liver weight and reduced serum urea levels were also noted in MeHg-exposed mice. Taken together, our findings demonstrated that a well-standardized exposure protocol to examine MeHg-induced neurotoxicity also produced systemic toxicity in mice, which was characterized by changes in markers of hepatic function as well as serum lipid homeostasis.

Full Text Available Testosterone like activity of seeds of Mucuna pruriens and its effects on serum biochemical metabolites in immature male rats were investigated. Forty eight immature male rats were divided into four equal groups. Rats of groups A and B were orally given ethanolic and aqueous extracts of Mucuna pruriens seeds daily at the dose rate of 500 mg/kg body weight, respectively, for 14 days. Rats of group C were injected with testosterone at the dose rate of 2.5 mg/kg body weight daily, while rats of group D served as controls. After 7 days, six rats from each group were euthanized, while the remaining six rats from each group were euthanized after 14 days of treatment. Rats given ethanolic extract gained higher weight compared to controls (P<0.05. Testis weight was the highest in rats treated with testosterone. The effect of treatments on the weight of the liver and the kidneys was non significant. Rats given ethanolic or aqueous extract had higher serum testosterone concentration than controls. Similarly, rats given ethanolic or aqueous extract had higher serum total proteins, total cholesterol and HDL cholesterol compared to controls. Moreover, ethanolic extract treated rats also had higher total cholesterol and HDL cholesterol than aqueous extract treated rats. However, differences in serum total proteins, total cholesterol and HDL cholesterol between control and testosterone injected rats were non significant. Serum triglycerides, LDL cholesterol and ALT activity did not differ among rats of four groups. Serum AST activity and urea were lower in rats treated with ethanolic or aqueous extract compared to controls. Thus, seeds of Mucuna pruriens had testosterone like activity and increased serum total proteins, total cholesterol and HDL cholesterol, with no adverse effects on the serum LDL cholesterol, liver or kidney functions.

Serum hyaluronic acid and biochemical models which require hyaluronic acid analysis are commonly used as predictors of liver fibrosis in patients with chronic liver disease, however biological variation data for hyaluronic acid are deficient. Four serial serum samples were obtained at weekly intervals from healthy volunteers and patients with chronic hepatitis B, chronic hepatitis C and non- alcoholic fatty liver disease (NAFLD; 20 in each group). The within-individual week-to-week variation (CVI) and reference change values for hyaluronic acid, α₂-macroglobulin and Hepascore were obtained. Hepascore is calculated from hyaluronic acid, α2-macroglobulin, bilirubin and γ-glutamyltransferase activity. Hyaluronic acid displayed large within-individual variation, the CVI values were 62% in healthy subjects, 38% in hepatitis C, 37% in hepatitis B and 36% in NAFLD patients. Hepascore CVIs were 43% in healthy subjects, 24% in hepatitis C, 28% in hepatitis B and 39% in NAFLD patients. α₂-Macroglobulin was much less variable with CVIs ranging from 4.4% to 7.6%. Bland-Altman plots of week-to-week variations showed rates of significant disagreement for samples collected in any 2 successive weeks varied from 5% in NAFLD patients to 8.3% in healthy subjects. When using non-fasting serum samples, hyaluronic acid and to a lesser extent, the Hepascore model display large within-individual variations in both health and chronic liver disease. This information is critical for interpreting the significance of both single measurements and changes in serial measurements.

Full Text Available The subject was represented and discussed at The National Week of Science and Technology, UFPE, an initiative from The Ministry of Science and Technology to encourage children and people in science and technology activities. The work aimed to renew the importance to transmit knowledge from simple, imaginative, biochemical models and interactive teaching. The stand tool contained an aquarium with fishes, five scale models showing peptide bond, carbohydrate inhibited lectin molecule, hemagglutination reaction, lectin-bacterium surface interaction and enzyme-substract-inhibitor. Posters described tropical fish importance and methods applied to obtain fish serum and organs to purify lectins and protein inhibitors as well as to extract tissue DNA; notions were transmitted on fish immunology and diseases. The students were attracted and impressed with the exotic fishes most cultivated in Brazil; they asked if it is necessary to kill the fish to extract lectin and about lectin importance. Students were also interested to know if all fish enzyme/inhibitors are favorable to the own fish organism. The work succeeded to inform and stimulate future scientists in the field and to awake their scientific curiosity.

Full Text Available This trial was performed to study the effects of replacing soybean meal (SBM with fermented rapeseed meal (RSM on growth performance, serum biochemistry variable and intestinal morphology of broilers. A total of 640 d-old Arbor Acres broiler chicks were randomly allocated to 4 dietary treatments, 4 pens per treatment and 40 birds per pen for a 6-wk feeding trial. In the four treatment groups, fermented RSM replaced soybean meal at 0, 5, 10, and 15%, respectively. On 21 d and 42 d, two birds from each pen were randomly selected and slaughtered. Blood samples and sections of duodenum, jejunum, and ileum were collected for measurement of serum biochemical variables and intestinal morphology, respectively. Results showed that body weight gain (BWG and feed conversion (FC were significantly (p<0.01 poorer for birds fed the 15% fermented RSM diet than those fed with 0, 5 and 10% fermented RSM diets during all periods. Compared with 0 and 5% fermented RSM groups, IgG content in the serum of birds in 10 and 15% fermented RSM groups was improved (p<0.01 urea nitrogen content of serum was reduced (p<0.01 during both growing and finishing periods. However, IgM, phosphorus and calcium levels increased (p<0.05 only during the growing period. Increased (p<0.05 villus height was observed in the duodenum and jejunum of broilers fed the diet with 10% fermented RSM. In addition, villus height to crypt depth ratio in the jejunum was significantly higher (p<0.01 for birds fed the diet with 10% fermented RSM than for those fed diets with 0, 5 and 15% fermented RSM. The present results suggest that RSM fermented with Lactobacillus fermentum and Bacillus subtilis is a promising alternative protein source and that it could be safely used replace up to 10% SBM in broiler diets.

Full Text Available The present study was conducted to evaluate the effects of infection of ewes with toxoplasmosis and/or brucellosis on someserum biochemical parameters. Ninety six samples of blood were collected from aborted ewes at different stages of gestation,suspected to be infected with toxoplasmosis and /or brucellosis from different regions in Nineveh governorate. The percentageof toxoplasma and brucella infection depending on Latex Agglutination Test (LAT and Rose Bengal Test were 21.88% and23.96% respectively. The results of biochemical analysis showed that infection with toxoplasma caused significant elevation ofserum activities of aspartate aminotransferase (AST, alanine aminotransferase (ALT and lactate dehydrogenase (LDH. Aswell as the concentrations of glucose, total protein and copper. Where as the activity of alkaline phosphatase (ALP and theconcentration of calcium and zinc were reduced. Infection with brucellosis caused a significant increased in serum AST, ALTand LDH, ALP and creatin phosphokinase (CPK activities, and glucose, zinc and cholesterol concentrations. While serumcalcium and total protein concentration were decreased. Association of toxoplasma and brucella infection induced significantelevation of serum AST, ALT and LDH and CPK activities and the concentrations of glucose and copper with significant reduction in serum ALP activity and both calcium and zinc concentrations. It was concluded from this study that infection ofewes with toxoplasma and/or brucella caused changes in some biochemical parameters in the serum.

The dynamics of 38 biochemical parameters of blood, serum and urine was studied in ten heifers during their oestrous cycle in a light house (80-340 lux) and a dark small house (10-40 lux). In the light stable a significant influence (P less than 0.05) was found to be exerted on five parameters and in the dark stable nine parameters, four being influenced in the same way in both houses: haematocrit value and haemoglobin in blood and cholesterol and progesterone in serum; the relationship of progesterone content in serum to the days of oestrous cycle was particularly high in the light house. The comparison of the parameters between the groups demonstrated a significant (P less than 0.05) influence of light regime, exerted on some days of the oestrous cycle upon the levels of inorganic phosphorus, total protein and aspartate aminotransferase activity (AST) in serum and upon haematocrit, haemoglobin and ketone bodies in the blood of heifers. However, the light regime did not influence the levels of progesterone which were somewhat higher in the light house but with no statistically significant difference from the dark house. A significant difference between the groups was obtained in the levels of sodium and phosphorus in urine (P less than 0.05) between the first and tenth days of the oestrous cycle. No differences in the oestrous cycle between the heifers in the light and dark stables were recorded. Neither was the duration of heat influenced significantly; it was only less manifest in the dark stable.

The purpose of this study is to determine the effect of L-ascorbic acid and alpha-tocopherol as well as combination of these vitamins with or without exposure to physical exercise on intensity of lipid peroxidation, activity of xanthine oxidase, activity of total antioxidative system, concentration of glutathione, and activity of catalase in the serum of guinea pigs. The experimental measurements of intensity of lipid peroxidation, activity of xanthine oxidase, activity of total antioxidative system, concentration of glutathione, and activity of catalase were done in the serum of guinea pigs. The animals were exposed to the test load to achieve exhaustion and the test was terminated when the animal for the third time to sink into the water. The results of this study demonstrated that endurance exercise of guinea pigs induced oxidative stress response in terms of increased lipid peroxidation and activity of xanthine oxidase in the serum of experimental animals. Our study investigated the antioxidant activity of L-ascorbic acid and alpha-tocopherol also measuring three protective markers in the serum: total antioxidant activity, content of glutathione and activity of catalase. The results obtained show that the vitamins influence the concentrations of above mentioned biochemical parameters, which points out their protective effect of swimming-induced oxidative stress. Single or combined administration of L-ascorbic acid and alpha-tocopherol caused significant inhibition of these markers indicating the important antioxidant activity of the vitamins. Results lead to conclude that the combined treatments with vitamins with or without exposure to physical exercise showed the clear synergistic effect..

The aim of this study was to determine the seroprevalence and hemato-biochemical manifestations of brucellosis in horses. Serum samples were screened for Brucella antibodies by Rose Bengal plate test (RBPT) and serum agglutination test (SAT). Blood samples were evaluated for hemato-biochemical parameters following standard procedures. Results indicated seroprevalence of brucellosis 20.13 and 16.23% in horses by RBPT and SAT, respectively. Brucellosis does not lead to any significant change in hematological and biochemical parameters in relation to age, sex, body condition and lactation except few parameters. The values of erythrocyte sedimentation rate, neutrophil, basophil and alkaline phosphatase significantly decreased in brucellosis positive animals as compared to healthy animals whereas lymphocytes and alanine aminotransferase were in opposite order. It was concluded from the results that prevalence of brucellosis in horse population is of concern; therefore, control measures should be opted so that its zoonotic threat is curtailed. (author)

Full Text Available Abstract Background With change in concepts of growth determination methods, there is a surge in the measurement of biomarkers for appraisal of growth status. Osteocalcin is a bone-specific protein and was observed to parallel the normal growth curve. Hence, the present study was intended to assess the levels of serum osteocalcin and serum insulin-like growth factor-1 (IGF-1 and compare them with cervical vertebral maturation index (CVMI stages. Methods The cross-sectional study was performed on 150 subjects (75 males and 75 females in the age group of 8–20 years and segregated into six CVMI stages. Serum osteocalcin and IGF-1 were estimated by ELISA. Mann-Whitney U test was used to compare the mean ranks of serum osteocalcin and serum IGF-1 with different CVMI stages. Spearman correlation was performed to find association between serum osteocalcin and serum IGF-1 across six CVMI stages. Results Peak serum IGF-1 levels were obtained at CVMI stages 4 and 3 for males and females, respectively, with insignificant difference between stages 3 and 4 in females. Peak serum osteocalcin levels were found at stage 5 and 3 for males and females with insignificant difference from other stages except stages 5 and 6 in males. A statistically significant correlation was seen between serum IGF-1 and serum osteocalcin across six CVMI stages (P < 0.01. Conclusions Osteocalcin followed IGF-1 across all CVMI stages but showed insignificant interstage differences.

Experiment was conducted to investigate the effects of borax, cysteamine and the mixture of two compounds on growth performance, serum biochemical indices, protein turn-over and nitrogen aggradation of sheep by using isotope ( 15 N-Gly) technique, nitrogen balance trial and serum testing. The results showed that both borax and cysteamine could increase the growth performance of sheep, especially the cysteamine and its mixture with borax, which increased average daily feed intake (P 3 ) and levothyroxine (T 4 ) of mixture were higher than that of control group (P<0.05), and the concentrations of growth hormone (GH) and insulin-like growth factors (IGF-1) were also significantly higher than those of control group (P<0.01). There was no significant difference of insulin (INS) between experiment groups and control group (P<0.05). Both mixture and borax contributed to increasing nitrogen retention, net nitrogen utilization, digestibility and biological value. Both borax and cysteamine accelerated protein degradation rate, apparent amino acid utilization rate and net amino acid utilization rate as well as biological value, body protein and oxidation rate, but the former was greater than the later.

Various uses of donkeys' milk have been recently proposed for human consumption on the basis of its nutritional characteristics. Improvements in milk fatty acid profile and animal oxidative status can be induced through dietary supplementation of phenolic compounds. The study aimed to evaluate in donkeys the effects of dietary supplementation with verbascoside (VB) on: (i) the fatty acid profile and vitamins A and E contents of milk during a whole lactation, and (ii) blood biochemical parameters and markers of oxidative status of the animals. At foaling, 12 lactating jennies were subdivided into two groups (n 6): control, without VB supplement; VB, receiving a lipid-encapsulated VB supplement. Gross composition, fatty acid profile and vitamins A and E contents in milk were assessed monthly over the 6 months of lactation. Serum total cholesterol, high-density lipoproteins cholesterol and low-density lipoproteins cholesterol, tryglicerides, non-esterified fatty acid, bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase, reactive oxygen metabolites, thiobarbituric acid reactive substances (TBARs), vitamin A and vitamin E were evaluated at 8 days after foaling (D0) and then at D90, D105 and D120 of lactation. In milk, the VB supplementation decreased the saturated fatty acids (Pdonkey's milk with a benefit on the oxidative status and serum lipidic profile of the animals.

Objective: To investigate a correlation between serum alkaline phosphatase level and body mass index in human subjects. Methods: The comparative cross-sectional study was carried out at the National Institute for Biotechnology and Genetic Engineering, Faisalabad, Pakistan, from April 2012 to June 2013. Blood serum alkaline phosphatase levels were estimated and the subjects were divided into three sub-groups on the basis of their body mass index: normal weight (<25kg/m2), overweight (25-27kg/m2) and obese (>27kg/m2) subjects. The serum samples were used for the estimation of clinically important biochemical parameters, using commercial kits on clinical chemistry analyser. Results: Of the 197 subjects, 97(49 percent) were obese and 100(51 percent) were non-obese. The serum alkaline phosphatase level increased in obese (214±6.4 IU/L) compared to the non-obese subjects (184.5±5 IU/L). Furthermore, a significant linear relationship (r=0.3;p-0.0001) was found between serum alkaline phosphatase and body mass index. Other biochemical variables were not correlated to the body mass index. Conclusion: Over activity and higher amounts of alkaline phosphatase were linked to the development of obesity. (author)

To describe the metabolic effects of epinephrine administration in New World camelids and investigate whether these effects are influenced by administration of insulin. 6 llamas and 8 alpacas (all adult castrated males). Prior to each experiment, food was withheld from camelids for 8 hours. On each of 2 consecutive days, alpacas were administered epinephrine (10 mg/kg, IM; time 0); alpacas were randomly assigned to receive regular insulin (0.2 U/kg, IV) immediately after epinephrine administration on one of those days. In llamas, the experiment was performed once after administration of epinephrine only. At 0, 30, 60, 90, 120, 150, 180, 210, and 240 minutes after treatment, blood samples were collected and several serum or plasma biochemical variables were assessed; in addition, plasma samples from llamas were assessed for insulin concentrations. Data were compared between days (alpacas only) and between time points. Administration of epinephrine induced mobilization of glucose, triglycerides, nonesterified fatty acids, and beta-hydroxybutyrate. A small increase in endogenous insulin concentration was detected in epinephrine-treated llamas, compared with baseline values. Overall, insulin administration decreased, negated, or delayed the epinephrine-associated increases in serum or plasma concentrations of circulating energy substrates, except that it augmented the epinephrine-associated increase in concentration of triglycerides. Epinephrine appeared to mobilize energy substrates in camelids and hence may be involved in the pathogenesis of disorders of glucose and fat metabolism. Insulin appeared to antagonize most of these effects, and its administration may have therapeutic value in camelids.

Polydatin, a hydroxystilbene derived from the rhizome of Polygonum cuspidatum, elicits hepatoprotective and neuroprotective effects through its anti-oxidant properties. The present study aimed to determine the effects of oral administration of polydatin in alcoholic patients in order to improve liver biochemical parameters, serum oxidative stress and mental state. We enrolled 20 chronic alcoholic patients hospitalized for rehabilitative therapy. The patients were divided into two groups receiving the following treatment regimes for two weeks: administration of an anti-oxidant nutritional supplement containing glutathione and vitamin C (group 1), or glutathione, vitamin C and polydatin (group 2). The results of the present study show that elevated plasma aspartate aminotransferase and alanine aminotransferase levels in patients after two weeks of alcohol withdrawal were significantly reduced by polydatin (group 2), when compared to group 1. Polydatin also significantly reduced lipid peroxidation levels. Finally, our preliminary data resulting from the analysis of the Mini-Mental Status suggest that polydatin improves cognitive performance. Daily dietary administration of polydatin should be considered for prevention and treatment of liver disease and cognitive impairment in alcoholic patients.

This Study aims to evaluate the role of soyabean diet in improvement of some biochemical activities of female rats received daily oral dose 0.89 mg/kg (1/10 LD 50 )of cytrolane as organophosphorus insecticide on some biochemical activities in female rats for ten consecutive days. Prior pesticide administration, female rats received soyabean at dose 58 g/kg body weight for 2 and 4 weeks. Under the effect of cytrolane administration, the results showed significant increase in serum triglycerides, total cholesterol, HDL-cholesterol and CPK mean levels. Total serum protein and progesterone levels were significantly decreased compared to the control. On the other hand, by the administration of soyabean prior cytrolane, it reduced considerably the changes produced by cytrolane on levels of serum cholesterol, triglyceride, HDL-cholesterol which decreased more or less compared to control, total protein level was within normal value. Also, serum progesterone concentration increased. Therefore, soyabean administration accelerated the normalization and improvement processes of the altered lipid profiles, protein and progesterone hormone

Argulosis hampers aquaculture production and alters the host physiology and growth. Azadirachtin is recognized as a potential antiparasitic agent against Argulus sp. The present study aimed to investigate the effect of different concentration of azadirachtin solution on haematological and serum biochemical parameters of Argulus-infested goldfish Carassius auratus. Ninety Argulus-infested goldfish were randomly divided into six equal groups. Fish of group 1-5 were treated with azadirachtin solution through bath of 1, 5, 10, 15 and 20 mg L(-1) as T1, T2, T3, T4 and T5, respectively, and group 6 was exposed to 2% DMSO solution without azadirachtin and considered as negative control T0(-). Along with six treatment groups, a positive control T0(+) of healthy goldfish free from Argulus infestation was also maintained. Parasitic mortality was evaluated after 3 days of consecutive bath treatment. After 7 days of post-treatment, the blood and serum were drawn from each of the treatment groups and haematological and serum biochemical parameters were evaluated. Total leucocyte count (TLC), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), blood glucose, total protein (TP), globulin, serum glutamate oxaloacetate transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT) were significantly (p azadirachtin have notable effects on activity of vital tissues function and physiology of the host. Argulus spp. from infested goldfish could be eliminated using bath treatment with solution of azadirachtin having concentration of 15 mg L(-1) and that also shifted haematological and serum biochemical parameters towards homeostasis.

Full Text Available Iron and zinc are found in similar foods and absorption of both may be affected by food compounds, thus biochemical iron and zinc status may be related. This cross-sectional study aimed to: (1 describe dietary intakes and biochemical status of iron and zinc; (2 investigate associations between dietary iron and zinc intakes; and (3 investigate associations between biochemical iron and zinc status in a sample of premenopausal women aged 18–50 years who were recruited in Melbourne and Sydney, Australia. Usual dietary intakes were assessed using a 154-item food frequency questionnaire (n = 379. Iron status was assessed using serum ferritin and hemoglobin, zinc status using serum zinc (standardized to 08:00 collection, and presence of infection/inflammation using C-reactive protein (n = 326. Associations were explored using multiple regression and logistic regression. Mean (SD iron and zinc intakes were 10.5 (3.5 mg/day and 9.3 (3.8 mg/day, respectively. Median (interquartile range serum ferritin was 22 (12–38 μg/L and mean serum zinc concentrations (SD were 12.6 (1.7 μmol/L in fasting samples and 11.8 (2.0 μmol/L in nonfasting samples. For each 1 mg/day increase in dietary iron intake, zinc intake increased by 0.4 mg/day. Each 1 μmol/L increase in serum zinc corresponded to a 6% increase in serum ferritin, however women with low serum zinc concentration (AM fasting < 10.7 μmol/L; AM nonfasting < 10.1 μmol/L were not at increased risk of depleted iron stores (serum ferritin <15 μg/L; p = 0.340. Positive associations were observed between dietary iron and zinc intakes, and between iron and zinc status, however interpreting serum ferritin concentrations was not a useful proxy for estimating the likelihood of low serum zinc concentrations and women with depleted iron stores were not at increased risk of impaired zinc status in this cohort.

Full Text Available The aim of this study was to compare the effect of new synthetic 4-thiazolidinone derivatives (potential anticancer compounds denoted as 3882, 3288 and 3833 and doxorubicin (positive control in free form and in their complexes with synthetic polyethylene glycol-containing nanoscale polymeric carrier on the biochemical indicators of nephrotoxicity in blood serum of rats. The concentration of total protein, urea, creatinine, glucose, ions of sodium, potassium, calcium, iron and chloride was measured. It was found that after injection of the investigated compounds, the concentration of sodium cations and chloride anions in blood serum was increased compared with control (untreated animals. Doxorubicin’s injection was accompanied by a decrease in the concentration of iron cations. The concentration of total protein, urea and creatinine decreased under the influence of the studied compounds. Complexation of these аntineoplastic substances with a synthetic polymeric nanocarrier lowered the concentration of the investigated metabolites substantially compared to the effect of these compounds in free form. The normalization of concentration of total protein, urea and creatinine in blood serum of rats treated with complexes of the studied compounds with the polymeric carrier comparing with increased concentration of these indicators at the introduction of such compounds in free form was found.

The present investigation included biochemical, radiometric, molecular studies and histopathological examination to evaluate the protective role of Antox tablets toward Arsenic toxicity in adult male albino rats (Rattus rattus). Arsenic were given as sodium arsenate to different groups in drinking water at a dose of 100 mg/L, for 3 and 6 weeks led to severe tissue damage as revealed by an elevation of serum total protein and alteration of serum protein fractions. Using radioimmunoassay it was found that serum total testosterone level was significantly decreased. The decreased level of total testosterone paralleled the observed testicular damage. Treatment of male rats with antioxidant (Antox) along with arsenic led to an improvement in both the biochemical and histological alterations induced by arsenic. Thus the protective role of Antox is attributed to its antioxidant and free radicals scavenging properties of its components (selenium, vitamin A acetate, ascorbic acid and vitamin E).

To investigate the value of circulating miR-152 in the early prediction of postoperative biochemical recurrence of prostate cancer. Sixty-six cases of prostate cancer were included in this study, 35 with and 31 without biochemical recurrence within two years postoperatively, and another 31 healthy individuals were enrolled as normal controls. The relative expression levels of circulating miR-152 in the serum of the subjects were detected by qRT-PCR, its value in the early diagnosis of postoperative biochemical recurrence of prostate cancer was assessed by ROC curve analysis, and the correlation of its expression level with the clinicopathological parameters of the patients were analyzed. The expression of circulating miR-152 was significantly lower in the serum of the prostate cancer patients than in the normal controls (t = －5.212, P = 0.001), and so was it in the patients with than in those without postoperative biochemical recurrence (t = －5.727, P = 0.001). The ROC curve for the value of miR-152 in the early prediction of postoperative biochemical recurrence of prostate cancer showed the area under the curve (AUC) to be 0.906 (95% CI: 0.809－0.964), with a sensitivity of 91.4% and a specificity of 80.6%. The expression level of miR-152 was correlated with the Gleason score, clinical stage of prostate cancer, biochemical recurrence, and bone metastasis (P 0.05). The expression level of circulating miR-152 is significantly reduced in prostate cancer patients with biochemical recurrence after prostatectomy and could be a biomarker in the early prediction of postoperative biochemical recurrence of the malignancy.

We tested whether serum total cholesterol levels might be associated with recent suicide attempts in subjects with major depressive disorder, after controlling for relevant individual characteristics. We conducted a comparative cross-sectional study including consecutive inpatients with major depressive disorder. We differentiated subjects admitted for a recent serious (violent or non-violent) suicide attempt and those without such recent history. Total cholesterol was measured from fasting blood tests. At univariate analyses, suicide attempters had levels of total cholesterol (174.0±45.7mg/dL) lower than non-attempters (193.9±42.6mg/dL) (p=0.004). This was confirmed among both violent (174.1±46.2mg/dL) and non-violent (173.8±46.1mg/dL) suicide attempters (p=0.035 and 0.016, respectively). However, logistic regression analyses, sequentially including demographic, clinical (comorbid alcohol and personality disorders), and biochemical factors, did not show any association between serum cholesterol and recent suicide attempts (p=0.172). Similar findings were observed in multinomial logistic regression analyses, for both violent (p=0.512) and non-violent (p=0.157) suicide attempts. Our findings do not support the hypothesis that serum cholesterol and suicide attempts are associated among subjects with major depressive disorder. The identification of valid and accessible biological markers of suicidal behaviors still represents a challenge for future research. Copyright © 2016 The Canadian Society of Clinical Chemists.

Vitamin D-deficient rickets (DR) has recently re-emerged among developed countries. Vitamin D deficiency can influence biochemical results of patients with fibroblast growth factor 23 (FGF23)-related hereditary hypophosphatemic rickets (HR), making differential diagnosis difficult. In the present study we evaluated the utility of serum FGF23 levels in the diagnosis of DR and during its treatment. The study group comprised 24 children with DR and 8 children with HR. Serum FGF23 levels and bone metabolism-related measurements were assessed. Serum FGF23 levels in patients with DR were less than 19 pg/ml, while those in patients with HR were more than 57 pg/ml. There were significant differences in serum levels of calcium, phosphate, parathyroid hormone, and 1,25-dihydroxyvitamin D, as well as tubular maximum phosphate reabsorption per glomerular filtration rate between patients with DR and HR, but these values were not fully mutually exclusive. In addition, serum FGF23 and phosphate levels were increased following treatment. Serum FGF23 level is the most critical biochemical marker for distinguishing DR from HR and might be a good indicator of biochemical response to the intervention. Serum FGF23 levels show utility for the diagnosis of DR and in the assessment of its response to treatment.

Effects of Discontinuous Administration of Dietary Mannan oligosaccharide and β-1,3-glucan on Hematological and Blood Serum Biochemical Parameters of Rainbow trout (Oncorhynchus mykiss

Directory of Open Access Journals (Sweden)

Reza Akrami

2016-04-01

Full Text Available Introduction Bans and restrictions of antibiotics as feed additives in fish culture in many countries have resulted in the increase in studies on alternative dietary supplements such as prebiotics to enhance the health and production of cultured fish. Prebiotics are nondigestible food ingredients that beneficially affect the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the colon. In addition, prebiotics promote the growth of lactic acid bacteria that are beneficial to health and lessen the density of pathogenic microorganisms. Because of the conservation of immune system, it is suggested that alternate administration of different immunostimulants may activate different parts of immune system of shrimps and take advantage of different immunostimulants to solve the problem of immunity fatigue and enhance the immunity continuously. However, there is no report on the discontinuous administration of immunostimulants for rainbow trout. Thus, considering the strategic importance of this species, the goal of this study was to assess the effects of discontinuous administration of dietary mannan oligosaccharide and β-1,3-glucan on hematological and blood serum biochemical parameters of rainbow trout. Materials and Methods A 6-week trial was conducted to compare the effects of discontinuous administration of dietary mannan oligosaccharide and β-1,3-glucan on hematological and blood serum biochemical parameters of rainbow trout (Oncorhynchus mykiss. Four feeding strategies were set, including feeding prebiotic-free diet continuously (control, feeding dietary prebiotic continuously (1.5 g kg-1, feeding dietary alternately (one week prebiotic+one week control diet and 2 Day prebiotic+5 Day control diet. Juveniles were fed the experimental diet in rate of 4% of the body weight per day, spread across two feeding time. At the end of the experiment, three fish were sampled randomly from each tank and were

Sharks are top-order predators in ocean food chains and the star attractions in aquaria worldwide. Unfortunately, blood biochemistry reference intervals (RI) have been determined for few species. The study aims to establish serum biochemical RI for free-living Sand Tiger sharks (Carcharias taurus) off eastern Australia. Thirty-seven sharks were captured and their sex, length, weight, reproductive maturity, and health status were recorded. After blood collection, serum analytes were quantified using standard analytical and statistical methods. Reference intervals, means, medians, and 90% confidence intervals were generated. Physiologic data from live and necropsied sharks were used to enhance the study results. Thirty healthy sharks were included in the study. Albumin could not be detected. With the exception of ALP activity, values were unaffected by sex, length, weight, age, and life-history stage. The means (RI) were: sodium 258 (249-267) mmol/L, potassium 5.0 (4.3-5.7) mmol/L, chloride 242 (227-257) mmol/L, inorganic phosphate 1.8 (1.7-2.0) mmol/L, total calcium 3.9 (3.3-4.4) mmol/L, magnesium 1.9 (1.6-2.2) mmol/L, glucose 2.7 (2.2-3.2) mmol/L, urea 377 (360-394) mmol/L, ALP 20 (8-31) U/L, ALT 3 U/L (no RI), AST 29 (13-45) U/L, CK 42 (5-79) U/L, total protein 30 (24-36) g/L, triglyceride 0.3 (0.1-0.6) mmol/L, cholesterol 1.4 (0.9-2.1) mmol/L, creatinine 32 μmol/L (no RI), total bilirubin 1.5 μmol/L (no RI), and osmolarity 1082 (1027-1136) mmol/L. These preliminary RI will assist with the clinical evaluation and treatment of captive and free-living Sand Tiger sharks worldwide. Studies with more animals will increase the precision of upper and lower reference limits. © 2015 American Society for Veterinary Clinical Pathology.

2010-01-01

Three groups of adult male albino rats were given either tap water (control) or saline water (1 % unrefined paludal salt dissolved in tap water or 1 % pure chemically synthesized NaCl in tap water). The experiment was carried out under hot summer conditions. At the end of 28 days of the treatment, blood samples were collected to follow up the biochemical alterations induced by paludal salt intake in kidney, liver and thyroid function tests besides serum electrolytes since unrefined paludal salt is being used extensively nowadays by Egyptian people as a table salt which comprises risks to human health.The results revealed that drinking water containing high level of either pure or unrefined crude salts led to significant elevation of serum urea, creatinine, sodium, potassium, aspartate amino transferase (AST), alanine amino transferase (ALT) and alkaline phosphatase (ALP). Serum triiodothyronine (T3) and thyroxine (T4) were significantly depressed in both groups received high levels of salt in their drinking water. The level of serum total protein was decreased and albumin was negatively affected by salinity of water especially in paludal group while serum globulin was significantly increased in the other two groups. The biochemical alterations observed in rats as a result of drinking water containing paludal salt were more pronounced than those occurred in rats drank tap water plus pure NaCl.

Aim: The present study is aimed to use bone mineral density (BMD) and various biochemical markers to predict the fracture risk at different menopausal statuses in Pakistani women. Method: Seventy women aged between 28-80 years at various menopausal statuses participated in this study. BMD (T score) of right calcaneus was determined using SAHARA ultrasound bone densitometer that measures the transmission of high frequency from heel. Various biochemical markers such as alkaline phosphates, calcium and inorganic phosphorus were measured from the serum of venous blood using standard kits of Randox. Results: Alkaline phosphates was raised in per menopausal, postmenopausal and postmenopausal with hysterectomy and ligation groups of women as compared to premenopausal women but did not achieve significance (P>0.05). Serum calcium level was significantly lower in postmenopausal women than premenopausal women and inorganic phosphorus decrease significantly when compared with premenopausal and postmenopausal with ligation and hysterectomy. BMD (T score) values of postmenopausal osteopenic and postmenopausal osteoprotic women were significantly lower than those of premenopausal women. BMD values of women under study have negative correlation with age, alkaline phosphates and calcium. Conclusion: Our study conclude that in addition to BMD, serum levels of alkaline phosphate, calcium and inorganic phosphorus can be valuable biochemical markers in predicting bone fracture risk at different menopausal states.

The aims of this study were to evaluate the effects of intramammary infusion of sage ( Salvia officinalis ) essential oil (EO) on milk somatic cell count (SCC), milk composition parameters and selected hematology and serum biochemical parameters in 20 Awassi ewes affected with subclinical mastitis. The dried leaves of sage were used to extract the EO by hydrodistillation. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of sage EO against Staphylococcus aureus were determined by the broth dilution method. Ewes were divided randomly into three main groups and received one of the following treatments; Group 1 (n=5): Dimethyl sulfoxide (DMSO) alone (5 ml; 0.2 ml of DMSO in 4.8 ml of saline), Group 2 (n=5): Amoxicillin alone (3 ml), and Group 3 (n=10): Sage EO (5 ml of sage EO solution [0.2 ml DMSO+1 ml EO+3.8 ml sterile saline]). All treatments were administered by intramammary infusion into each teat twice per day for 3 consecutive days. Milk samples for SCC and milk components determination and whole blood samples for hematology and serum biochemical analyses were collected before treatment (T0) and at 24 (T24) and 48 (T48) h after the last treatment. The MIC and MBC of sage EO against S. aureus were 12.5% and 6.1%, respectively. SCC was decreased significantly (psage EO and amoxicillin treated groups. Milk fat and lactose were increased significantly (psage EO and amoxicillin treated ewes while no significant changes were observed in the percentages of solids-not-fat, protein and total solids. No significant effects of sage EO treatment on any of the hematology or serum biochemical parameters were observed. There were no local or systemic side effects observed in any of the treated ewes. However, further clinical trials are warranted to determine safety and possible withdrawal times in milk before its recommendation for use in organic operations. In this study, the intramammary infusion of sage EO to ewes affected with

Objective: To investigate the clinical significance of changes of levels of biochemical markers of bone metabolism in patients with type 2 diabetes mellitus. Methods: Serum osteocalcin (BGP, with RIA), Ca alkaline phosphatase (ALP) and random specimen urinary deoxypyridinoline (DPD, with chemiluminescence assay), Ca, creatinine levels were measured in 40 patients with type 2 diabetes mellitus and 31 controls. Results: Serum BGP levels in diabetic patients were much lower than those in the controls (P<0.05); while urinary DPD/Cr ratio and Ca/Cr ratio were significantly higher in the patients than those in the controls (P<0.05, P<0.05). Serum Ca and ALP levels were about the same in the two groups. Conclusion: Loss of bone mass in diabetic patients are due to both decreased bone formation and increased bone resorption. Determination of the levels of the biochemical markers of bone metabolism (BGP, DPD......) could be applied for early detection of osteoporosis. (authors)

Patterns of serum biochemical parameters vary among horse breeds. The objective of the present study was to compare serum lipoproteins of Iranian Caspian ponies with those of other horses (Arabs and Thoroughbreds) in the Iranian region. Serum lipoprotein values were determined by agar-agarose gel electrophoresis and measured by scan densitometry. Moreover, serum triglyceride and cholesterol concentrations were determined and the results were analysed by one-way analysis of variance. Serum triglyceride and cholesterol values were 1.13 +/- 0.23 and 2.38 +/- 0.18 mmol/l in Caspian ponies, 1.96 +/- 0.49 and 1.92 +/- 0.25 mmol/l in Arab horses and 1.38 +/- 0.26 and 2.17 +/- 0.53 mmol/l in Thoroughbred horses. The relative percentages of alpha- (72.63 +/- 17.76%) and beta-lipoproteins (29.10 +/- 5.49%) in serum electrophoretic tracings from Caspian ponies were not significantly different from those of other horses (p > 0.05). The lipoprotein phenotype in Caspian ponies may be useful for evaluating metabolic diseases.

Malignancies are characterized by several drastic metabolic changes, one of which is a progressive rise in the levels of serum copper. This rise in serum copper is documented across all malignancies and across malignancies in several species. This study aims to explore in vitro the effect of increased copper levels on the structure of the blood protein human serum albumin. Exposure of human serum albumin to physiologically relevant copper concentrations for 21 days resulted in structural modifications in the protein which were evident by changes in the intrinsic florescence. A loss of the predominantly alpha helical structure of human serum albumin was recorded along with a tendency to form protein aggregates. This aggregation was characterized by Thioflavin T and Congo Red assays. Rayleigh light scattering and turbidity assays confirmed aggregation. The aggregates were visually confirmed using transmission electron microscopy. This is the first report implicating increased copper levels as a cause of aggregation of blood proteins in malignancies. The physiological and biochemical implications of this phenomenon are discussed. Copyright © 2017. Published by Elsevier Inc.

Full Text Available Enrofloxacin, an antimicrobial agent used to treat bacterial diseases is well tolerated by cats at recommended dosage (5 mg/kg. To investigate the tolerance of high-dose of the Hipralona Enro-I® (5% enrofloxacin solution in cats, 28 urban cats (11 males and 17 females between the weight of 1.3 and 2.4 kg were randomly assigned to a control group (n=4 and three treatment groups (n=8. Each treatment groups were injected low-dose enrofloxacin (5 mg/kg, IM, high-dose enrofloxacin (15 mg/kg, IM, and very high-dose enrofloxacin (25 mg/kg, IM once daily for seven consecutive days. Blood samples were collected from jugular vein before injection of enrofloxacin in the hind limb muscles of cats as self-control, and at 3rd, 7th, 14th, and 21st days after first drug injection. Samples were tested for various hematological and serum biochemical parameters. The systemic tolerance during experiment was investigated via monitoring of behavior and general physical examination. Hematological and serum biochemical parameters were not significantly different between groups. In addition, there was no statistically difference between various sampling days for any treatment group in each parameter. Furthermore, there was no change in the behavior and the general health condition of cats in the control and the three experimental groups. As serum biochemical indications of hepatotoxication and nephrotoxication were not observed. It was concluded that muscular injection of enrofloxacin in doses up to 25 mg/kg (5ED50 for seven consecutive days was tolerated by cats.

This study was conducted to determine the changes in biochemical parameters of blood and tissue mineral levels caused by various levels of dietary cadmium (Cd) and the effects of zinc on cadmium-induced changes in broilers. A total of 210 days old broiler chicks were randomly distributed into 7 dietary groups of 30 chicks in each. Group 1 was feed basal diet and served as control group. The diets of the groups 2, 3 and 4 were supplemented with 50, 75 and 100 mg Cd/kg, respectively. Groups 5, 6 and 7 received 50, 75 and 100 mg Cd /kg plus 40 mg Zn/kg which added to the basal ration from one day to 42 days. Water and feed were provided ad libitum. The results showed that addition of Cd in the ration of broiler caused the significant reduction in live body weight as well as body weight gain and significant increase in serum total protein, globulin, urea, creatinine and activities of AST, ALT, ALP, LDH and GGT. In addition, Cd caused significant increases in triiodothyronine (T3), T3/T4 ratio and lipid peroxidation. On the other hand, decrease in calcium, phosphorus, zinc and cholesterol was observed while serum glucose did not affect by cadmium.Supplementation of zinc in the diet of broiler improved the reduction in body weight and body weight gain and also increased calcium, phosphorus and zinc and improved liver and kidney functions

2016-01-01

Osteoporosis and fractures are complex conditions influenced by an interplay of genetic and environmental factors. The aim of the study was to investigate three biochemical parameters including total serum calcium, total serum alkaline phosphatase (sALP) and albumin in relation to bone mineral density (BMD) at the lumbar spine and femoral neck (FN), and with all-type of low-trauma fractures in Maltese postmenopausal women. Levels were also correlated with age and physical activity. A case-control study of 1045 women was performed. Women who suffered a fracture were classified as cases whereas women without a fracture history were included as controls subdivided into normal, osteopenic, or osteoporotic according to their BMD measurements. Blood specimens were collected following good standard practice and testing was performed by spectrophotometry. Calcium and sALP levels were weakly correlated with FN BMD levels (calcium: r = -0.111, p = 0.002; sALP: r = 0.089, p = 0.013). Fracture cases had the lowest serum levels of calcium, sALP and albumin relative to all other control groups, which decreased with increasing age, possibly increasing fracture risk. Biochemical levels were lowest in women who sustained a hip fracture and more than one fracture. Biochemical parameters decreased with reduced physical activity; however, this was most evident for fracture cases. Reduced physical activity was associated with lower BMD levels at the hip, and to a lower extent at the spine. In conclusion, results suggest that levels of serum calcium and albumin could be indicative of fracture risk, whereas calcium levels and to lower extent sALP levels could be indicators of hip BMD.

Serum parathyroid hormone (PTH), phosphorus, and calcium levels are surrogate outcomes that are central to the evaluation of drug treatments in chronic kidney disease (CKD). This systematic review evaluates the evidence for the correlation between drug effects on biochemical (PTH, phosphorus, and calcium) and all-cause and cardiovascular mortality end points in adults with CKD. Systematic review and meta-analysis. Adults with CKD. Randomized trials reporting drug effects on biochemical and mortality end points. Drug interventions with effects on serum PTH, phosphorus, and calcium levels, including vitamin D compounds, phosphate binders, cinacalcet, bisphosphonates, and calcitonin. Correlation between drug effects on biochemical and all-cause and cardiovascular mortality. 28 studies (6,999 participants) reported both biochemical and mortality outcomes and were eligible for analysis. Associations between drug effects on surrogate biochemical end points and corresponding effects on mortality were weak and imprecise. All correlation coefficients were less than 0.70, and 95% credible intervals were generally wide and overlapped with zero, consistent with the possibility of no association. The exception was an inverse correlation between drug effects on serum PTH levels and all-cause mortality, which was nominally significant (-0.64; 95% credible interval, -0.85 to -0.15), but the strength of this association was very imprecise. Risk of bias within available trials was generally high, further reducing confidence in the summary correlations. Findings were robust to adjustment for age, baseline serum PTH level, allocation concealment, CKD stage, and drug class. Low power in analyses and combining evidence from many different drug comparisons with incomplete data across studies. Drug effects on serum PTH, phosphorus, and calcium levels are weakly and imprecisely correlated with all-cause and cardiovascular death in the setting of CKD. Risks of mortality (patient

Full Text Available The research was performed on 40 chicken broilers of Cobb provenience to investigate the effect of dietary black cumin seed oil on some blood biochemical parameters in chicken broilers. 40 chicken broilers who were included in the 42 days lasting experiment were divided into two groups, each one of 20 individuals. Group K was the control – with no added oil in feed mixture and the second group P was the experimental one – chickens were fed with 0,025 g of p.o. administered black cumin seed oil. Feed and water supplies were ad libitum. Microclimate conditions (light, temperature and airflow were maintained according to the technological procedure. Blood samples were taken from the wing vein of all animals from both groups at age of 25, 32 and 39 days. The following blood serum biochemical parameters were determined: total lipids, triglycerides, total cholesterol, albumen and calcium. Dietary black cumin seed oil significantly (P<0.05 affected serum lipid components, particularly total lipids, but not albumen and calcium in chicken broilers. Possible reason for these findings could be dietary fat component as well as fatty-acid composition of added black cumin seed oil. Key words: black cumin seed oil, chicken broilers, blood serum biochemical parameters, fatty acid composition of oil

Full Text Available Toxic metals are widely found in our environment and humans are exposed to them via water contaminated air food and soil. Aluminum AL belongs to this group of toxic metals. Its neurological effects are well documented but effects on acid and alkaline phosphatases are poorly studied and this the essence of this study. Toxicity of aluminum was investigated based on the elevation of acid and alkali phosphatases in serum of male Wistar albino rats after days 7 and 14 of aluminum 0.38 3.8 and 38mgkg body weight administration respectively. The results showed significant increase p0.05 in serum acid phosphatase in the test animals given 38kgkg after days 14 while serum alkali phosphatase increased significantly p 0.05 in the test animals given 3.8 and 38 mgkg after days 7 and 14 when compared to the control animals. However lower dose 0.38mgkg showed increase in both serum acid and alkali phosphatases respectively but were statistically non-significant p0.05 at 7 and 14 as compared to control animals.

Full Text Available Background: The increase in prevalence of coronary heart disease, type 2 diabetes, obesity and abnormal blood lipid levels has raised the question of a possible relationship between these conditions and the consumption of sugar. Objectives: This study investigated the sugar consumption of financially-restricted Black women in Mangaung, South Africa. Method: Five hundred women were selected randomly and divided into younger (25–34 years and older (35–44 years groups. Dietary intake, sociodemographic status, anthropometry and biochemical data were obtained. Total sugar (TS and added sugar (AS consumption were compared between older and younger women as well as sociodemographic, anthropometric and biochemical categories. Results: AS intake contributed 12% and 13% of total energy intake in younger and older women, respectively. AS consumption was higher in younger women living in brick houses and those who possessed a microwave oven. In older women, it was higher in husband-headed households. Underweight women with the lowest body mass index had higher sugar consumption than overweight and/or obese women. Women with a lower body fat percentage had a higher AS consumption than women with a high body fat percentage. Sugar consumption was significantly lower in younger women with elevated serum lymphocytecounts. TS and AS consumption was higher in younger women with elevated serum glucose levels. Older women with elevated serum insulin had a significantly higher TS consumption compared to those with normal insulin concentrations. Conclusion: The amounts of TS and AS consumed by women in this observational study were unlikely to contribute to overweight and/or obesity.

2001-03-01

Full Text Available Biochemical changes during fasting or the withholding of feed for 5 day were studied in serum of camelids (dromedary camel, llama and ruminants (sheep, steers. Camels maintained low levels of 13-hydroxybutyrate (BHB and high levels of glucose but showed some increased levels of non-esterified fatty acid (NEFA and urea when fasting. Sheep and steers showed a rise in serum BHB and much higher increases of NEFA than camels and llamas. Sheep showed decreased serum glucose. The llama showed some increase in BHB but NEFA was lower than the other three species. The results indicate that camelids have a unique ability to control lipolytic and gluconeogenic activity to prevent or postpone the state of ketosis. Understanding and manipulation of these metabolic mechanisms in cattle and sheep could have great benefit to the livestock industry.

Studies suggest that Chronic Kidney Disease (CKD) is a global burden health associated with significant comorbid conditions. Few biochemical parameters have gained significance in predicting the disease progression. The present work aimed to study the association of the simple biochemical parameter of serum bilirubin level with the estimated glomerular filtration rate (eGFR), and to assess their association with the co-morbid conditions in CKD. We recruited 188 patients with CKD who attended a Nephrology out-patient department. eGFR values were calculated based on the serum creatinine levels using CKD-EPI formula. Various biochemical parameters including glucose, creatinine, uric acid, total and direct bilirubin were assayed in all study subjects. Study subjects were categorized into subgroups based on their eGFR values and their diabetic status and the parameters were compared among the different subgroups. We observed a significantly decreased serum bilirubin levels (p bilirubin levels (r = 0.92). We also observed a significant positive correlation between the eGFR levels and the direct bilirubin levels (r = 0.76). On multivariate linear regression analysis, we found that total and direct bilirubin independently predict eGFR, after adjusting for potential confounders (p bilirubin may help in predicting the early progression of CKD and more so in diabetic CKD.

Full Text Available For the generation of cell-based therapeutic products, it would be preferable to avoid the use of animal-derived components. Our study thus aimed at investigating the possibility to replace foetal bovine serum (FBS with autologous serum (AS for the engineering of cartilage grafts using expanded human nasal chondrocytes (HNC. HNC isolated from 7 donors were expanded in medium containing 10% FBS or AS at different concentrations (2%, 5% and 10% and cultured in pellets using serum-free medium or in Hyaff®-11 meshes using medium containing FBS or AS. Tissue forming capacity was assessed histologically (Safranin O, immunohistochemically (type II collagen and biochemically (glycosaminoglycans -GAG- and DNA. Differences among experimental groups were assessed by Mann Whitney tests. HNC expanded under the different serum conditions proliferated at comparable rates and generated cartilaginous pellets with similar histological appearance and amounts of GAG. Tissues generated by HNC from different donors cultured in Hyaff®-11 had variable quality, but the accumulated GAG amounts were comparable among the different serum conditions. Staining intensity for collagen type II was consistent with GAG deposition. Among the different serum conditions tested, the use of 2% AS resulted in the lowest variability in the GAG contents of generated tissues. In conclusion, a low percentage of AS can replace FBS both during the expansion and differentiation of HNC and reduce the variability in the quality of the resulting engineered cartilage tissues.

Full Text Available Effects of ambient copper was investigated on serum stress markers, sodium and enzyme levels in Common carp (Cyprinus carpio L. over a 14-d exposure period. Fish were exposed to 0, 25 and 100 μg L-1 copper (as copper sulfate and blood was sampled at 0, 3, 7 and 14 d after exposure. Serum profile was significantly affected by copper concentration, sampling time and their interaction. Increase in serum levels of cortisol, glucose, alanine aminotransferase and aspartate aminotransferase and decrease in serum sodium levels were observed in both copper-exposed groups, 3 d after copper exposure, which lasted until the end of the experiment. It is concluded that copper exposure causes stress response and sodium loss in common carp. Likewise alanine aminotransferase and aspartate aminotransferase increase after exposure which might be as results of either tissue damage or stress.

This experiment aimed to evaluate the effect of calcium soap of fatty acid (CSFA) supplementation on serum biochemical and hormones and ovarian activity during out-of-the-breeding season in ewes. Twelve crossbred ewes, 2-3 years of age and weighting 45–55 kg, were allocated into two equal groups. The first group was control and the other was treated with 50 g/head of CSFA. All ewes were fed basal diet and treated with 60 mg of medroxy progesterone acetate intravaginal sponge for 12 day. At the third day of sponge removal, the CSFA-treated group was given 50 g/head of CSFA daily for two estrous cycles. During the estrus phase, ovarian activity was detected using ultrasonography in both groups. All ewes were then subjected to natural breeding and conception rate. Blood samples were collected from all ewes during treatment period. Results revealed significant (P < 0.05) increases in serum cholesterol, triglycerides, low-density lipoprotein cholesterol, glucose, and progesterone levels with decrease in calcium and phosphorous levels in treated group. In treated group, normal-size ovaries and more than one follicle on the ovaries were detected and pregnancy rate increased. In conclusion, CSFA supplementation was effective to maintain the reproductive performance when ewes were out of the breeding season. PMID:22629155

Thyroid hormones influence energy expenditure, glucose, and lipid metabolism. The association between serum follistatin level and thyroid function statuses has seldom been evaluated. The objectives of this study were to compare serum follistatin concentrations in different thyroid function statuses and to evaluate the associations between serum follistatin and free thyroxine (fT4) levels. In this study, 30 patients with hyperthyroidism (HY group) and 30 euthyroid individuals (EU group) were recruited. The patients of HY group were treated with antithyroid regimens as clinically indicated, whereas no medication was given to EU group. The demographic and anthropometric characteristics, biochemical data, serum levels of follistatin, and thyroid function of both groups at baseline and at the 6th month were compared. Data of all patients were pooled for the analysis of the associations between the levels of follistatin and fT4. At baseline, the HY group had significantly higher serum follistatin levels than the EU group (median [Q1, Q3]: 1.81 [1.33, 2.78] vs 1.13 [0.39, 1.45] ng/mL, P hyperthyroidism had higher serum follistatin levels, which decreased after receiving antithyroid treatment. In addition, the serum follistatin concentrations were positively associated with serum fT4 levels in patients with hyperthyroidism or euthyroidism. PMID:26844494

In this study, serum adiponectin level was evaluated in 35 primary breast cancer patients and 10 healthy females, before and after treatment to assess if there is a relation between it and breast cancer, and to find out if it has a prognostic value. Serum adiponectin level was significantly lower in all and postmenopausal breast cancer patients before taking any type of treatment, and non-significantly lower in locally advanced breast cancer patients after treatment by 4 cycles of neoadjuvant chemotherapy than healthy controls. Non-significant elevations was shown after treatment by surgery, and also after completing treatment by surgery followed by taking 2 cycles of adjuvant chemotherapy followed by treatment by radiotherapy in case of premenopausal locally advanced breast cancer patients. Triglycerides showed significantly higher level in all groups of patients. There was statistical negative correlation between serum adiponectin level and body mass index (BMI) in postmenopausal healthy controls, and between serum adiponectin level and BMI, triglycerides in all and postmenopausal breast cancer patients before taking any type of treatment. In conclusion, this study suggests that low serum adiponectin level is likely to be associated with increased breast cancer risk, particularly among postmenopausal women. The association between obesity and breast cancer risk might be partly explained by adiponectin

Fatty liver is a major metabolic disorder in dairy cows and is believed to result in major economic losses in dairy farming due to decreased health status, reproductive performance and fertility. Currently, the definitive means for diagnosing fatty liver is determining the fat content of hepatic tissue by liver biopsy, which is an invasive and costly procedure, making it poorly suited to dairy farms. Therefore, the key aim of this study was to investigate the measurement of serum paraoxonase-1 (PON1), an enzyme exclusively synthesized by the liver, as a sensitive noninvasive biomarker for diagnosis of fatty liver in dairy cows. A comparative cohort study using serum specimens from Holstein-Friesian dairy cows (46 healthy and 46 fatty liver cases) was conducted. Serum PON1 (paraoxonase, lactonase and arylesterase) activity and other biochemical and hematological parameters were measured. We found that serum PON1 activity was lower (Pratio (+LR), negative likelihood ratio (-LR), diagnostic odd ratio (DOR) and overall diagnostic accuracy in diagnosing fatty liver. The present results indicate that addition of serum PON1 activity measurement to the biochemical profile could improve the diagnosis of fatty liver in dairy cows, which would have a considerable clinical impact and lead to greater profitability in the dairy industry.

The aim of this study was to evaluate a biochemical marker with different elements of a normal blood serum and centrifuged blood serum after a different rotation system. For this technique, we used five fractions of a blood Concentrated Growth Factors system (bCGF) and a particular device for the different rotation program. Blood samples were collected from 10 volunteers aged between 35 and 55 in the Operative Unit of the “Sapienza” University of Rome with only a fraction of different biochemical elements. Through an individual blood phase separator tube of venous blood, active factions of serum and 4 fractions of red buffy coat were taken. The biochemical markers with 14 elements were examined at times: P1-11 minutes, P2-12minutes, P3-15 minutes. Exclusively biological materials which are normally applied in the regeneration techniques for different defects and lesions were used with this technique. After specific rotation programs, a different result was obtained for each cycle: P1, P2, P3. In test tubes obtained by separated blood, we observed a higher concentration of proteins, ions, and other antigens compared to normal blood plasma. Examining the biochemical results of different elements, we observed an increase (P≤0,01). Since each person’s DNA is different, we could not have the same results in 5 fractions of blood concentration, we did, however, find a good increase in only a fraction of proteins, immunoglobulin and different ions. We obtained five fractions after centrifugation, and we had an increase in different biochemical elements compared to normal blood (P≤0,01) which is significant at different times. These biochemical elements were stimulated by different growth factors, which are used by the immune system, and they induced the formation of hard and soft tissues and good regeneration.

Full Text Available This study was conducted to investigate the effect of supplementation of lysine (Lys and methionine (Met on growth performance, nutrients digestibility and serum biochemical indices for growing sika deer fed crude protein (CP deficient diet. Sixteen 5-month-old growing male sika deer were randomly assigned to 4 groups receiving diets (n=4: i CP-adequate (16.63% diet; ii CP-deficient (13.77% diet with 3 g/kg Lys; iii CP-deficient with 3 g/kg Lys and 1 g/kg Met; iv CP-deficient diet with 3 g/kg Lys and 2 g/kg Met. The digestibility of dry matter P<0.01, organic matter (P<0.01, CP (P<0.01, serum albumin (P<0.01, and total protein (P<0.01 concentrations of groups receiving CP-adequate or Met supplementation were improved. The average daily gain (P=0.10, gain to feed ratio (P=0.07, the digestibility of acid (P=0.07 and neutral detergent fibre (P=0.09, and the serum globulin (P=0.08 concentrations had a tendency to increase as the Met or CP level increased. Meanwhile, blood urea nitrogen (P<0.01 and alanine aminotransferase (P<0.01 were decreased for CP-deficient, but no response to Met-added diets; aspartate aminotransferase (P=0.04 depressed for both CP-deficient and Met-added diets. Therefore, amino acids added to CP-deficient diets show high efficiency: they remain among the simplest ways for growth performance, while cutting down environmental waste and economic consumption.

To establish a safe anesthetic protocol with little effect on blood biochemical values and IV glucose tolerance test (IVGTT) results in Japanese black bears (Ursus thibetanus japonicus). 16 captive female Japanese black bears (5 to 17 years of age). Bears were randomly assigned to 4 treatment groups (4 bears/group) in which various treatment combinations were administered via blow dart: tiletamine HCl and zolazepam HCl (9 mg/kg) alone (TZ), TZ (6 mg/kg) and acepromazine maleate (0.1 mg/kg), TZ (6 mg/kg) and butorphanol tartrate (0.3 mg/kg), or TZ (3 mg/kg) and medetomidine HCl (40 μg/kg). Glucose injection for the IVGTT was started 130 minutes after TZ administration. Blood samples were obtained before, at, and intermittently after glucose injection for measurement of biochemical variables as well as plasma glucose and serum insulin concentrations during the IVGTT. Rectal temperature, pulse rate, and respiratory rate were assessed every 15 minutes during the experiment. Induction and maintenance of anesthesia were safely achieved with little adverse effect on cardiopulmonary function when each of the 4 anesthetic regimens was used, although mild hypothermia was induced. No difference was evident between treatment groups in blood biochemical values. Blood glucose and insulin concentration profiles during the IVGTT were similar among the bears given TZ, with or without acepromazine or butorphanol, but hyperglycemia and hypoinsulinemia developed in bears given TZ with medetomidine. All 4 anesthetic regimens yielded chemical restraint without affecting clinical and biochemical values in bears, but medetomidine appeared to affect IVGTT results. For this reason, medetomidine should not be used when anesthetizing bears for IVGTTs.

The effect of single acute oral doses of 29 and 58 mg/kg of cyanox (an organophosphorus pesticide) on selected biochemical and hematological parameters in male rats were investigated. This compound inhibited blood acetylcholine esterase (AChE) significantly, over 72 hours post-treatment with the higher dose level. Serum alkaline phosphatase (ALP) was significantly depressed, 48 hr after treatment with 58 mg/kg. Serum bilirubin was elevated significantly after 48 and 24 hr of treatment with 29 and 58 mg/kg, respectively. Serum cholesterol increased significantly over 48 hr post-treatment with both dose levels.Hypertriglyceridemia was noticed only in the higher dose group. Serum total lipids were increased significantly at both dose levels. A slight treatment-related effect was observed in serum creatinine level. The hematological investigations revealed the occurrence of macrocytic normochromic anemia that was more evident in the lower dose group

Full Text Available Aim: The aim of the study was to establish the baseline hematology and serum biochemistry values for Indian leopards (Panthera pardus fusca, and to assess the possible variations in these parameters based on age and gender. Materials and Methods: Hemato-biochemical test reports from a total of 83 healthy leopards, carried out as part of routine health evaluation in Bannerghatta Biological Park and Manikdoh Leopard Rescue Center, were used to establish baseline hematology and serum biochemistry parameters for the subspecies. The hematological parameters considered for the analysis included hemoglobin (Hb, packed cell volume, total erythrocyte count (TEC, total leukocyte count (TLC, mean corpuscular volume (MCV, mean corpuscular Hb (MCH, and MCH concentration. The serum biochemistry parameters considered included total protein (TP, albumin, globulin, aspartate aminotransferase, alanine aminotransferase (ALT, blood urea nitrogen, creatinine, triglycerides, calcium, and phosphorus. Results: Even though few differences were observed in hematologic and biochemistry values between male and female Indian leopards, the differences were statistically not significant. Effects of age, however, were evident in relation to many hematologic and biochemical parameters. Sub-adults had significantly greater values for Hb, TEC, and TLC compared to adults and geriatric group, whereas they had significantly lower MCV and MCH compared to adults and geriatric group. Among, serum biochemistry parameters the sub-adult age group was observed to have significantly lower values for TP and ALT than adult and geriatric leopards. Conclusion: The study provides a comprehensive analysis of hematologic and biochemical parameters for Indian leopards. Baselines established here will permit better captive management of the subspecies, serve as a guide to assess the health and physiological status of the free ranging leopards, and may contribute valuable information for making

To determine the serum and intraerythrocyte concentrations of vasoactive ions in patients of diabetes mellitus of either gender with hypertension. The study was conducted on 48 volunteers. Out of 48, 24(12 men and 12 women) were hypertensive patients with diabetes mellitus. Remaining (12 men and 12 women) were normal healthy subjects. Biochemical estimations were done by flame photometry and spectrophotometry. Data were analyzed by Two-way ANOVA followed by Newman-Keuls test. A decrease in serum concentrations of sodium, calcium, magnesium, phosphorus, chloride and intraerythrocyte potassium and an increase in the levels of glucose, haematocrit and intraerythrocyte sodium was observed in both male and female patients with diabetes mellitus and hypertension. No significant changes were observed in serum potassium levels. The results suggest that dysregulations of electrolyte balance caused by hyperinsulinemia or altered glucose metabolism may lead to hypertension. (author)

Purpose: Biochemical control using serial posttreatment serum prostate specific antigen (PSA) levels is being increasingly used to assess treatment efficacy for localized prostate cancer. However, no standardized definition of biochemical control has been established. We reviewed our experience treating patients with localized prostate cancer and applied three different commonly used definitions of biochemical control to determine if differences in therapeutic outcome would be observed. Methods and Materials: Between January 1987 and December 1991, 480 patients with clinically localized prostate cancer received external beam irradiation (RT) using localized prostate fields at William Beaumont Hospital. The median dose to the prostate was 66.6 Gy (range 58-70.4) using a four-field or arc technique. Pretreatment and posttreatment serum PSA levels were recorded. Over 86% (414 of 480) of patients had a pretreatment PSA level available. Three different definitions of biochemical control were used: (a) PSA nadir 20), and 5-year actuarial rates of biochemical control were calculated using the three biochemical control and one clinical local control definitions. For Group 1, 5-year actuarial rates of biochemical control were 84%, 90%, and 96% for Definitions 1-3 and clinical local control, respectively. For Group 2, 5-year actuarial control rates were 45%, 54%, 74%, and 92% for the four definitions, respectively. For Group 3, 5-year actuarial control rates were 26%, 31%, 63%, and 100% for the four definitions, respectively. For Group 4, 5-year actuarial control rates were 24%, 24%, 50%, and 100% for the four definitions, respectively. Finally, for Group 5, 5-year actuarial control rates were 5%, 14%, 15%, and 89% for the four definitions, respectively. Depending on the definition used, statistically significant differences overall in outcome rates were observed. Differences between all four definitions for all pairwise comparisons ranged from 5 to 53% (p < 0

Full Text Available Many toxins from scorpion venoms cause neurotransmitters release by activating the autonomic system. The aim of the present work was to determine osmotic fragility of red blood cells (RBCs and serum biochemical changes produced by the venom of Odonthobuthus doriae (O. doriae, a dangerous species of scorpion in Iran. For this study we selected 2 groups, each one containing 10 New Zealand white rabbits weighing 2 ± 0.2 kg. In vivo and in vitro osmotic fragilities as well as packed cell volume (PCV were determined. Serum was separated and used for determination of glucose, blood urea nitrogen (BUN, creatinine, uric acid (UA, triglycerides, cholesterol, aspartate aminotransferase (AST, EC 2.6.1.1, and alanine aminotransferase (ALT, EC 2.6.1.2. Results indicate that Odonthobuthus doriae venom (0.5 mg/kg, IV causes a significant increase (p<0.05 of serum glucose, UA, PCV, ALT, and AST. Increase was also observed in BUN, but it was not statistically significant. On the other hand a significant decrease (p<0.05 was observed in triglycerides and cholesterol levels. Increased in vivo osmotic fragility of RBCs was significant too, but in vitro osmotic fragility did not show a significant change. These results support the hypothesis that the biochemical variation caused by scorpion venom can be due to an autonomic storm and release of catecholamines.

Full Text Available Objective: The aim of this study is to assess the antioxidant properties of onion on biochemical serum factors, antioxidants and testicular tissues in Wistar rats after consuming tartrazine. Materials and Methods: Forty male Wistar were divided into four groups of 10. The first group was used as the control group and were given only water without additives, group 2 were given tartrazine, group 3 were given tartrazine plus onion juice and the fourth group which was given only onion juice through gastric gavage. The experiment was conducted for 60 days, then the antioxidant activities superoxide dismutase (SOD, catalase (CAT, glutathione peroxidase (GPx and biochemical parameters namely high density lipoprotein (HDL, low density lipoprotein (LDL and testosterone together with the histopathological studies (sperm count and testicular weight were measured. Results: Tartrazine caused a decrease in the activity of antioxidant enzymes (SOD, CAT, GPX and a decrease in the level of testosterone and HDL and also a decrease in sperm count and testicular tissue weight. Tartrazine caused an increase in the LDL levels. Conclusion: Results showed that consumption of tartrazine is associated with production of free radicals and in turn causes significant decrease in antioxidant activities and biochemical serum factors which damage the cellular compartments of the testis. Onion as an antioxidant in this study reduces the damaging effects of tartrazine on the enzymatic activities of antioxidant and biochemical serum factors.

The present study was conducted to determine the changes in concentrations of hormones and growth factors and their related receptor gene expressions in crop tissue, relative organ weight, and serum biochemical parameters in male and female pigeons during incubation and chick-rearing periods under artificial farming conditions. Seventy-eight pairs of 60-week-old White King pigeons with 2 fertile eggs per pair were randomly divided into 13 groups by different breeding stages. Serum prolactin and insulin-like growth factor-1 (IGF-1) concentrations in crop tissue homogenates were the highest in both male and female pigeons at 1 d of chick-rearing (R1), while epidermal growth factor (EGF) in female pigeons peaked at d 17 of incubation (I17) (P < 0.05). mRNA expression of the prolactin and EGF receptors in the crop tissue increased at the end of incubation and the early chick-rearing stage in both sexes. However, estrogen, progesterone, and growth hormone receptor expression each decreased during the early chick-rearing stage (P < 0.05). In male pigeons, IGF-1 receptor gene expression reached its peak at R7, while in female pigeons, it increased at the end of incubation. The relative weight of breast and abdominal fat in both sexes and thighs in the males was lowest at R7, and then gradually increased to the incubation period level. Serum total protein, albumin, and globulin concentrations increased to the highest levels at I17 (P < 0.05). Total cholesterol, triglyceride, and low-density lipoprotein reached their highest values at I17 in male pigeons and R25 in female pigeons (P < 0.05). In conclusion, hormones, growth factors, and their receptors potentially underlie pigeon crop tissue development. Changes in organs and serum biochemical profiles suggested their different breeding-cycle patterns with sexual effects.

Full Text Available The aim of present study was to analyse biochemical parameters in blood of rabbits after epicatechin administration during two weeks. Animals (adult female rabbits, body weight 4 ± 0.5 kg were divided into four groups: control group (C and experimental groups (E1 – E3. Experimental groups received epicatechin in injectable form at 10 µg.kg-1 in E1, 100 µg.kg-1 in E2 and 1000 µg.kg-1 in E3 for 14 days three times a week. After two weeks of exposure the blood was collected, in blood serum selected biochemical parameters [(glucose, urea, bilirubin, cholesterol, triglycerides, total proteins, calcium (Ca2+, magnesium (Mg2+, phosphorus (P] were analysed by automatic analyzer Microlab 300 (Merck®, Germany. Potassium (K+, sodium (Na+, chlorides (Cl- were analysed by EasyLyte Plus (Medica Corporation, USA. Epicatechin had no significant influence on the observed parameters (P > 0.05. The present study has shown that the serum cholesterol level and triglycerides levels in the E2 and E3 groups were higher than in the control group, however without significant differences (P > 0.05.

Full Text Available Serum calcium and phosphorus levels are the important biochemical markers of bone in health and disease. The normal range of these bone biochemical markers belong to the populations with different racial and nutritional states. In order to determine normal range of these elements, fasting sera of 1463 (619 males and 749 females, 20-69 years old healthy subjects were evaluated using Selectra autoanalyser. The subjects had not disorder of bone and predisposing conditions for osteoporosis. The mean of serum calcium level was 9.26 mg/dl (CI: 95%, 9.22-9.31 mg/dl for females and 9.43-9.54 mg/dl for males. The mean of serum phosphorus level was 4.12 mg/dl (CI: 95%, 4.16-4.24 mg/dl for females and 3.97-4.07 for males. Therefore, calcium and phosphorus levels are in concordance to international standard normal range in Bushehr port.

Hypercholesterolemia is an important risk factor linked to the alteration of blood hematology and clinical chemistry associated with the development and progression of atherosclerosis. Previous studies have demonstrated the safety and potential health benefits of Baccaurea angulata (BA) fruit. We hypothesized that the oral administration of BA fruit juice could ameliorate the alteration in the hematological and biochemical biomarkers of diet-induced hypercholesterolemic rabbits. The aim of this study was to investigate the effects of different doses of BA juice on the hematological and biochemical biomarkers in normo- and hypercholesterolemic rabbits. Thirty-five healthy adult New Zealand White rabbits were assigned to seven different groups for 90days of diet intervention. Four atherogenic groups were fed a 1% cholesterol diet and 0, 0.5, 1.0, and 1.5mL of BA juice per kg of rabbit daily. The other three normal groups were fed a commercial rabbit pellet diet and 0, 0.5, and 1.0mL of BA juice per kg of rabbit daily. Baseline and final blood samples after 90days of repeated administration BA juice were analyzed for hematological parameters while serum, aortic and hepatic lysates were analyzed for lipid profiles and other biochemical biomarkers. The alteration of the hemopoietic system, physiological changes in serum and tissues lipid profiles and other biochemicals resulting from the consumption of a high-cholesterol diet were significantly (Pjuice. Improvements of the biomarkers in rabbits were dose-dependent, markedly enhanced at the highest dose of juice (1.5mL/kg/day). The results suggest potential health benefits of the antioxidant-rich BA fruit juice against hypercholesterolemia-associated hematological and biochemical alterations in the rabbit.

Purpose: Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiologic entity characterized by headache, blurred vision and seizures with typical parieto-occipital predominantly vasogenic edema, occasionally with cytotoxic edema. The association between the degree and type of edema in PRES with biochemical parameter, especially serum lactate dehydrogenase, has not been determined. Material and methods: Thirty-five patients with typical clinical symptoms and characteristic MR imaging findings of PRES were included in this study. The extent of brain edema was graded on the anatomical distribution by 2 observers blinded to patients’ clinical record, as well as the type of brain edema determined on DWI and ADC map. The levels of biochemical parameters were correlated with the degree of edema and compared between different types of edema. Results: Serum LDH concentrations between patients with cytotoxic edema and with vasogenic components were not statistically different (NWU test, U = 93.0, Z = 1.818, P = 0.069). Only serum lactate dehydrogenase (LDH) concentration was significantly correlated with the score of brain edema distribution (Spearman's rho correlation, r = 0.721, P = 0.00). No relationship was found between other biochemical parameters and the degree and type of brain edema. Conclusion: Increased serum LDH level, which plays an essential role in endothelial injury, may be a potential risk factor for the development of edema in PRES.

Full Text Available This paper presents the results of some biochemical parameters obtained in the laboratory of “Elena Beldiman” Emergency Hospital Barlad, and in the”Dr. Stoian –Dr. Ungureanu”Private Medical Practice on 10 patients diagnosed with multiple myeloma during 2005-2011. Numerous researches over serum proteins with the help of various methods ( refractometry have shown the presence of some changes in protein fractions of blood serum. These changes express the change of the normal ratio between these fractions, that means disorders in colloidal structure of blood. The results of the electrophoresis analysis, also in accordance with those from the scholarly literature, show that the changes in the condition of the blood serum are due to the increase in the globulins fractions which is linked to the growth of the immunological processes, the antibodies synthesis being especially closely linked to gammaglobulinic fraction

Full Text Available The objective of our study was to determine blood hematological and serum chemistry values for a population of free-living European brown hares and to investigate differences related to age. The European brown hare (Lepus europaeus is a species of hare naturally occurring in northern, central and western parts of Europe and southwestern Asia. The blood samples were collected from 25 hares (15 adults and 10 juveniles shot during regular hunting seasons in 4 hunting grounds located in Danube lowland. Following parameters were analyzed: WBC, LYM, GRA, RBC, HGB, HCT, MCV, MCH, MCHC on blood samples, and glucose, total proteins, urea, bilirubin, cholesterol, Ca, P, Na, K, Cl on serum. WBC count was higher in adults (2.86.109.l-1 than in young hares (2.71.109.l-1. RBC count and HGB concentration were higher in young hares (RBC=8.94.1012.l-1, HGB=184.43 g.l-1 than in adults (RBC=8.38.1012.l-1, HGB=177.59 g.l-1. No significant differences were found in other hematology parameters. Biochemical indicators of age were evaluated and an increased content of glucose in adult individuals was found (a = 9.39 mmol.l-1, j = 8.48 mmol.l-1. The increased level of urea in blood serum was observed as almost significant in juvenile individuals (a = 6.11 mmol.l-1, j = 6.94 mmol.l-1, but also reduction of bilirubin was observed (a = 5.19 mmol.l-1, j = 4.23 mmol.l-1. Other monitored biochemical parameters were fairly balanced. All evaluated hematology and serum chemistry parameters of brown hares were within the physiological range with relatively low differences.

The food consumption and serum nutritional status of people living in the Kathmandu valley, Nepal, were examined to obtain actual data for comparison with our previous findings. A dietary survey of 45 males and 60 females was carried out in March 1997 by the 24-hr dietary recall method and nutrient intake was calculated from food tables of India and Japan. Fasting venous blood samples were obtained and serum biochemical parameters were measured using clinical kits. The mean body mass index values was at about the same level in both sexes, although the mean percentage body fat of females was higher than that of males, and vice versa for packed red cell volume. The main foods consumed by both sexes, were rice, potatoes, meats, milk & dairy products and vegetables, with a difference in the amounts consumed. Females did not drink alcoholic beverages. The mean daily intakes of energy, protein, lipids, iron and vitamin B group for the males were higher than those for the females, while those of vitamins A and C for the males were lower than those for the females. The mean values of serum biochemical parameters for both sexes were generally at the normal levels, but those of ALT and TG were at the higher end of the normal range. Differences of correlation between food groups and between serum parameters were observed depending on the sex, however, no clear relationship between food and nutrient intake and serum biochemical parameters were observed. The present food intake study revealed that the amounts of food consumption for both sexes, especially for the females, were mostly insufficient although the serum parameters were at the normal levels. The energy intake of both sexes was lower than that of estimated requirements and those in Terai region. The relatively high serum TG level of the subjects may be due to the consumption of large amounts of cereals containing much carbohydrate. Our findings suggested a marked influence on food consumption by food price and income

The present study was designed to determine possible contributory impact of malaria infection on some biochemical markers in subjects with HIV co-infection in order to know if they are adverse or protective. Participants were recruited at the Voluntary Counseling and Testing Unit, Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria and grouped into: (i) Malaria and HIV co-infection group (n = 45); and (ii) HIV infected group without concurrent malaria infection (n = 57). Standard laboratory methods were used for the HIV and Plasmodium falciparum antigen screening, malaria parasite density, CD4+ T-cell count, packed cell volume, white blood cell count, serum iron and albumin concentrations. The results showed that serum iron and albumin were significantly reduced and raised respectively in 'Malaria-HIV co-infection group' compared with 'HIV infection group' (p < 0.05 and p < 0.05). A positive association was observed between age and serum iron concentration in malaria and HIV co-infected group (r = 0.580; p < 0.05) while negative associations were observed between PCV and serum iron (r = - 0.388; p < 0.05) and between CD4+ T-cells and serum iron concentration (r = -0.362; p < 0.05) in malaria and HIV co-infected group. The CD4+ T-cell count, WBC count, PCV were not significantly different between the Malaria-HIV co-infection group and HIV infection group. In the present study serum iron and albumin concentrations were the most sensitive indicators that showed the contributory impact of malaria infection on biochemical index in HIV co-infected subjects. The findings suggest that at the defined stage of HIV infection in the present study, malaria co-infection may moderate the impact of HIV infection on iron metabolism and hepatic synthesis of albumin.

Full Text Available Background: In hepatitis C virus (HCV, infection viral and IL28B genotype along with many clinical and biochemical factors can influence response rates to pegylated interferon plus ribavirin (Peg-IFN-a/R therapy and progression to chronic hepatitis C (CHC. Aims: The present study was conducted to determine the effect of biochemical and risk factors on treatment outcome in CHC patients in relation to their viral and host genotype. Settings and Design: The present study was a prospective Pe- IFN efficacy study consisting of Peg-IFN-a/R therapy for 24–48 weeks including 250 HCV infected patients. Materials and Methods: Biochemical parameters were determined by Beckman Coulter AU680 automated analyzer. HCV and Interleukin 28B (IL28B genotyping were carried out by polymerase chain reaction-restriction fragment length polymorphism and viral load was determined by quantitative real-time PCR. Results: Wild outnumbered the variant genotypes in rs 12979860, rs 12980275, and rs 8099917 SNP of IL28B gene. Sustained virological response (SVR SVR and viral genotype were significantly associated with age, hepatic steatosis, low-grade varices, and serum aspartate transaminase levels (at the end of treatment (P < 0.05. In addition, SVR was significantly influenced by body mass index (BMI, insulin resistance, serum low-density lipoprotein , and ferritin levels (P < 0.05. Viral genotype 1 infected patients had higher serum cholesterol and triglyceride levels (P < 0.05. Conclusions: Although the IL28B sequence variation is the major factor that can influence response rates to antiviral therapy, viral and biochemical factors also have a definite role to play in the diagnosis, etiology, and treatment outcome in HCV-infected patients.

Lack of seasonal variation in bone mass and biochemical estimates of bone turnover

Three previous studies have indicated a seasonal variation in bone mineral content, with values during the summer being 1.7% to 7.5% higher than during the winter. We have examined the seasonal influence on both bone mass, biochemical estimates of bone turnover and vitamin D metabolites in 86 healthy women, aged 29-53 years. All participants were followed up for 2 years with examinations every 6 weeks or 3 months. Bone mineral content in the proximal and distal part of the forearm (single photon absorptiometry) did not reveal any significant seasonal variation, whereas bone mineral density of the lumbar spine (dual photon absorptiometry) indicated that the highest values occurred in winter. None of the biochemical parameters showed any statistically significant cyclical changes. Serum concentrations of 25-hydroxyvitamin D and 24,25-dihydroxyvitamin D3 showed a highly significant seasonal variation, whereas the serum 1,25-dihydroxyvitamin D concentration was virtually unchanged. We conclude that seasonal variation in bone mineral content and bone turnover should not be taken into account when interpreting data from longitudinal studies of healthy pre- and postmenopausal women on a sufficient vitamin D nutriture

The aim of this study was to assess the ability of serum bone-specific alkaline phosphatase (bone ALP), creatinine-corrected urinary collagen crosslinks (CTx) and calcaneus bone mineral density (BMD) to identify postmenopausal women who have an increased risk of osteoporotic fractures. Calcaneus BMD and biochemical markers of bone turnover (serum bone ALP and urinary CTx) were measured in 512 community-dwelling postmenopausal women (mean age at baseline 69 years) participating in the Hawaii Osteoporosis Study. New spine and nonspine fractures subsequent to the BMD and biochemical bone markers measurements were recorded over an average of 2.7 years. Lateral spinal radiographs were used to identify spine fractures. Nonspine fractures were identified by self-report at the time of each examination. During the 2.7-year follow-up, at least one osteoporotic fracture occurred in 55 (10.7%) of the 512 women. Mean baseline serum bone ALP and urinary CTx were significantly higher among women who experienced an osteoporotic fracture compared with those women who did not fracture. In separate age-adjusted logistic regression models, serum bone ALP, urinary CTx and calcaneus BMD were each significantly associated with new fractures (odds ratios of 1.53, 1.54 and 1.61 per SD, respectively). Multiple variable logistic regression analysis identified BMD and serum bone ALP as significant predictors of fracture (p = 0.002 and 0.017, respectively). The results from this investigation indicate that increased bone turnover is significantly associated with an increased risk of osteoporotic fracture in postmenopausal women. This association is similar in magnitude and independent of that observed for BMD.

To explore the relationship between the levels of serum adiponectin and urinary albumin excretion rate in patients with type 2 diabetes nephropathy, the serum levels of adiponectin and the levels of urinary albumin excretion rate in diabetes patients before and after treatment with pioglitazone were tested by ELISA and automatic biochemical analyzer respectively. The results showed that the serum levels of adiponectin in DM and DN group were lower than that of normal controls(P<0.01), but they gradually increased with progression (P<0.01). The serum adiponectin level was positively correlated with urinary albumin excretion rate (r= 0.284, P<0.05). The urinary albumin level decreased (P<0.01) and the serum levels of adiponectin increased after treatment with pioglitazone in DN group. The serum levels of adiponectin and urinary albumin excretion rate may play important role in the indication of treatment of diabetes. (authors)

To determine the serum hyaluronic acid (HA) levels as biochemical marker of hepatic fibrosis and cirrhosis and correlate it with the degree of hepatic fibrosis and cirrhosis. This study was performed on 100 patients of chronic liver disease whose liver biopsies had been carried out. Fifty healthy controls were also included in the study. Routine liver function tests, hepatitis serology and serum hyaluronic acid levels were carried out on patients and controls. Liver biopsy of 100 patients revealed that 21 were in stage 0 fibrosis, 38 in stage 1 fibrosis, 26 in stage 3 fibrosis and 15 in stage 4 fibrosis. Mean Serum HA (mean +- SD) concentration in patients were 189 +- 98 mg/L vs. 21 +- 10 mg/L of healthy controls. The difference observed was statistically significant (p < 0.001). Patients in stage 4 fibrosis had significantly higher (p <0.001) mean serum HA concentration as compared to other stages of liver fibrosis. Diagnostic accuracy of serum HA at marginally elevated level of 60 mg/L determined the sensitivity 78.4 %, specificity 80.9%, positive predicted value 93.9% and negative predicted value of 50%. Serum HA is a useful non-invasive marker of liver fibrosis. There is a strong positive correlation between serum HA levels and degree of liver fibrosis. The concentration of serum HA rises according to progression of liver fibrosis and levels are highest in patients with liver cirrhosis. (author)

Full Text Available Background: This study aimed to examine the relationship between changes in systemic vitamin B12 concentrations with pro-inflammatory cytokines, anthropometric factors and biochemical markers of cardiometabolic risk in a Saudi population. Methods: A total of 364 subjects (224 children, age: 12.99 ± 2.73 (mean ± SD years; BMI: 20.07 ± 4.92 kg/m2 and 140 adults, age: 41.87 ± 8.82 years; BMI: 31.65 ± 5.77 kg/m2 were studied. Fasting blood, anthropometric and biochemical data were collected. Serum cytokines were quantified using multiplex assay kits and B12 concentrations were measured using immunoassay analyzer. Results: Vitamin B12 was negatively associated with TNF-α (r = −0.14, p < 0.05, insulin (r = −0.230, p < 0.01 and HOMA-IR (r = −0.252, p < 0.01 in all subjects. In children, vitamin B12 was negatively associated with serum resistin (r = −0.160, p < 0.01, insulin (r = −0.248, p < 0.01, HOMA-IR (r = −0.261, p < 0.01. In adults, vitamin B12 was negatively associated with TNF-α (r = −0.242, p < 0.01 while positively associated with resistin (r = 0.248, p < 0.01. Serum resistin was the most significant predictor for circulating vitamin B12 in all subjects (r2 = −0.17, p < 0.05 and in children (r2 = −0.167, p < 0.01 while HDL-cholesterol was the predictor of B12 in adults (r2 = −0.78, p < 0.05. Conclusions: Serum vitamin B12 concentrations were associated with pro-inflammatory cytokines and biochemical markers of cardiometabolic risks in adults. Maintaining adequate vitamin B12 concentrations may lower inflammation-induced cardiometabolic risk in the Saudi adult population.

Piper betle L. (PB) belongs to the Piperaceae family. The presence of a fairly large quantity of diastase in the betel leaf is deemed to play an important role in starch digestion and calls for the study of weight loss activities and metabolite profile from PB leaf extracts using metabolomics approach to be performed. PB dried leaves were extracted with 70% ethanol and the extracts were subjected to five groups of rats fed with high fat (HF) and standard diet (SD). They were then fed with the extracts in two doses and compared with a negative control group given water only according to the study protocol. The body weights and food intakes were monitored every week. At the end of the study, blood serum of the experimental animal was analysed to determine the biochemical and metabolite changes. PB treated group demonstrated inhibition of body weight gain without showing an effect on the food intake. In serum bioassay, the PB treated group (HF/PB (100mg/kg and 500mg/kg) showed an increased in glucose and cholesterol levels compared to the Standard Diet (SD/WTR) group, a decrease in LDL level and increase in HDL level when compared with High Fat Diet (HF/WTR) group. For metabolite analysis, two separation models were made to determine the metabolite changes via group activities. The best separation of PCA serum in Model 1 and 2 was achieved in principle component 1 and principle component 2. SUS-Plot model showed that HF group was characterized by high-level of glucose, glycine and alanine. Increase in the β-hydroxybutyrate level similar with SD group animals was evident in the HF/PB(500mg/kg) group. This finding suggested that the administration of 500mg/kg PB extracts leads to increase in oxidation process in the body thus maintaining the body weight and without giving an effect on the appetite even though HF was continuously consumed by the animals until the end of the studies and also a reduction in food intake, thus maintaining their body weight although they

Directory of Open Access Journals (Sweden)

Diganta Das

2015-01-01

Full Text Available Introduction: Olanzapine is a commonly used antipsychotic. Prolactin elevation is a common adverse effect of anstipsychotics, and serum prolactin elevation is seen in about 30% patients treated with olanzapine. There are confounding results about dose dependency of olanzapine and prolactin elevation, and also the duration of treatment. Method: Fifty six patients, 36 male and 20 female, who were taking olanzapine for any condition for more than a month at a constant dose were enrolled in the study. Patients’ age, weight, body mass index (BMI, serum prolactin levels, and some biochemical values were recorded. Patients were taken from the review outpatient department (OPD after due consent. Results: Five each in male and female groups showed elevation of serum prolactin (estimated to be high if >20 ng/dl for males, and >25 ng/dl for females. In females, the elevation was found at lesser dose of olanzapine (13 mg/day, in males 18 mg/day and early in the treatment (2.4 months vs. 9.7 months in males. Males tended to show raised prolactin with higher doses of olanzapine (mean 18 mg/day. Females (26.31% also showed higher prevalence of prolactin elevation compared to males (13.51%. No other parameter was found to modify the prolactin levels. Conclusion: Olanzapine causes elevation of serum prolactin, though lesser degree than some other antipsychotics. Females are more prone to have raised serum prolactin with olanzapine compared to males. However, the elevation seems to be transient. Higher doses of olanzapine tend to cause elevation of serum prolactin. Serum prolactin estimation in patients taking olanzapine may be undertaken to maintain quality life, particularly in females.

The Sida cordifolia L. (Family: Malvaceae) is a widely allocated herb by folk tribes of Gujarat state of India for the treatment of coronary manifestations. However, no published data relevant to use of the plant is available. The aim of the present study was to evaluate the antioxidant and biochemical profile of hydroalcoholic extract of Sida cordifolia L. (HESC) leaves against myocardial infarction (MI) in rats. Albino rats were administered HESC (100 and 500 mg/kg) and propranolol (10 mg/kg) once daily orally for 30 days. At the end of treatment period, MI was induced by administering isoproterenol (ISO) or by subjecting heart to ischemia reperfusion injury (IRI). Endogenous biomarkers (LDH and CK-MB) and antioxidants (SOD and catalase) were estimated in serum/perfusate and heart tissue homogenate (HTH). The LDH and CK-MB activities were elevated in HTH and depleted in serum/perfusate of HESC and propranolol groups when compared to ISO/IRI control. Further, it was found that both doses significantly increased endogenous antioxidants in HTH. Moreover, biochemical findings were supported by histopathological observations. The result confirm, at least in part, for the use of Sida cordifolia in folk medicine to treat MI.

This paper aimed to study the effect of Ramadan fasting on biochemical and clinical parameters and compliance for dialysis. A prospective multicenter observational cross-sectional study comparing fasting with a non-fasting stable adult hemodialysis patients for demographic and biochemical parameters, compliance with dialysis, inter-dialytic weight gain, pre- and post-blood pressure, and frequency of intradialytic hypotensive episodes was carried out. Six hundred thirty-five patients, of whom 64.1% fasted, were studied. The fasters were younger (53.3 ± 16.2 vs. 58.4 ± 16.1 years; P = 0.001) but had similar duration on dialysis (P = 0.35). More fasters worked (22.0% vs. 14.6%; P = 0.001) and missed dialysis sessions during Ramadan. No differences were noted between groups in sex, diabetic status, or dialysis shift or day. There were no differences in the pre- and post-dialysis blood pressure; serum potassium, albumin or weight gain; diabetic status; sex; and dialysis shift time or days. However, serum phosphorous was significantly higher in the fasting group (2.78 ± 1.8 vs. 2.45 ± 1.6 mmol/L; P = 0.045). There were no intragroup differences in any of the parameters studied when comparing the findings during Ramadan with those in the month before Ramadan. Fasters were significantly younger and more likely to be working, to miss dialysis sessions, and to have higher serum phosphorous levels. No other differences were observed. © 2015 International Society for Hemodialysis.

The Reef Stonefish (Synanceia verrucosa) is one of the most dangerous venomous fish known, and has caused occasional human fatalities. The present study was designed to examine some of the pathological effects of the venom from this fish in Sprague Dawley rats. Crude venom was extracted from venom glands of the dorsal spines of stonefish specimens collected from coral reefs in the Gulf of Aqaba (in the northeastern branch of the Red Sea). The rats were given intramuscular injections of the venom and acute toxicity and effect on selected serum marker enzymes as well as normal architecture of vital organs were evaluated. The rat 24 h LD50 was 38 μg/kg body weight. The serum biochemical markers; alanine transaminase (ALT), lactate dehydrogenase (LDH) and creatine kinase (CK) increased after 6 h of administration of a sub lethal dose of the venom and remained significantly raised at 24 h. Amylase levels also significantly increased after venom injection. The venom caused histological damage manifested as an interstitial hemorrhage, inflammatory cell infiltration, and necrosis. The demonstrated rises in the levels of different critical biochemical parameters in the serum may have led to the observed abnormal morphological changes in these organs. These results may account for some of the clinical manifestations observed in victims of stonefish envenomation. Thus, the presented data provide further in vivo evidence of the stonefish toxic effects that may threaten human life and call for the need for special measures to be considered.

The Effect of the amount of ligand HEDTMP on biochemical properties of 153 Sm-HEDTMP is studied. The biochemical properties include partition coefficient of 153 Sm-HEDTMP in n-octanol-water which is measured by shake-flask method, combination characteristic with BSA (bovine serum albumin) which is measured through precipitation by TCA (trichloroacetic acid) and adsorption characteristic on HA (hydroxyapatite) which is measured with the same method used in 153 Sm-EDTMP. It is found that, with the increasing in the amount of ligand, partition coefficient of 153 Sm-HEDTMP. It is found that, with the increase in the amount of ligand, partition coefficient of 153 Sm-HEDTMP in n-octanol-water decreases, so does combination percentage with BSA, but the adsorption percentage on HA shows a little and unremarkable decrease. Considering the relationships between these three biochemical properties and in vivo metabolism of 153 Sm-HEDTMP this study supports the view that an appropriate high amount of ligand should be applied in practical use

In order to investigate the feasibility of serum creatine kinase (CK) and blood urea nitrogen (BUN) in monitoring pre-competition training of badminton athletes, the pre-competition training load of 20 badminton athletes was studied, and serum CK and BUN were determined before, immediate and next morning after training. The results showed that after intensive training for one week, serum CK levels were significantly increased by 57.53 mmol/L (P0.05). After intermittent training, there was significant difference in the average increased levels of serum CK in athletes (P0.05). It was concluded that serum CK was one of the biochemical indicators monitoring the training load sensitivity of badminton athletes, but BUN was of little value in monitoring the training load. Both serum CK and BUN recovered slowly after one-week intensive training and intermittent training, suggesting the metabolic mechanism of human body in training needs further study.

The goal of the work was a study of exhaustive weightlifting exercise effect on prolonged changes in physiological and biochemical variables characterized functional status of skeletal muscles. An exercise gave rise to significant blood lactate concentration increase that was indicative of an anaerobic metabolism to be a predominant mechanism of muscle contraction energy supply. A reduction of m. rectus femoris EMG activity (amplitude and frequency), tonus of tension and an increase in tonus of relaxation were found immediately after exercise. Both EMG amplitude and frequency were increased 1 day post-exercise. However, after 3 days of recovery, EMG amplitude and frequency were decreased again and, in parallel, blood serum creatine kinase (CK) activity was significantly increased. After 9 recovery days, all measured variables with the exception of CK were normalized. A significant reverse correlation was found between blood serum lactate concentration and m. rectus femoris EMG activity at the same time points. Blood serum CK activity and m. rectus femoris EMG and tonus variables were observed to be significantly reversely correlated on the 3rd post-exercise day. Presented data demonstrate that exhaustive exercise-induced muscle injury resulted in phase alterations in electrical activity and tonus which correlated with lactate concentration and CK activity in blood serum.

The purpose of this study is to evaluate the effect of feeding diet artificially contaminated with aflatoxin B 1(AFB1) at level 0.2 mg kg"-"1 AFB1, and gamma (γ) irradiated (10, 20, and 30 kGy) on reducing the deleterious effects of laying hens Golden Montaza (GM) biochemical attributes. These include liver weight, AFB1 liver residue content, AST, ALT, ALP, creatinine, total proteins, albumin and globulin, as well as, the levels of T3, T4, TSH, FSH, LH, progesterone hormone and hepatic histology. At 38 week of age, groups of laying hens were fed on a normal non-contaminated diet (G1), aflatoxin-contaminated diet (G2), and irradiated contaminated diets (G3, G4 and G5) for 3 weeks, as a duration period. When the hens reached 42 weeks of age, they were fed on normal diet for 3 weeks, as a recovery period. Results showed that AST, ALT, ALP, and creatinine significantly increased in AFs treated groups in comparison with those received AFs-containing diet and irradiated up to 30 kGy. Layers fed contaminated diet of AFB1 suffered from a lower level of total proteins, albumin and globulin. Meanwhile, the results showed that the level of serum T4 was lower, but conversely the levels of FSH were higher for those fed on diets contaminated with AFB1 compared to those fed irradiated contaminated diets with AFB1, no significant change occurred in serum blood T3, TSH, LH and progesterone in all tested groups. Treated contaminated diets with γ-irradiation at 30 kGy reduced the incidence and severity of hepatic histology. The 30 kGy radiation dose was more effective, in this respect, in all biochemical indices. For recovery period diets non-contaminated with AFB1, the results showed improvements in all biochemical indices and recovered the hepatic structure with increasing the recovery period especially for those fed on irradiated diets through the experimental duration. In conclusion, feeding of diets contaminated with AFB1 altered the blood profiles, and damaged the liver

A total of 24 rats were divided into 4 groups: control, stress, extract alone, and stress + extract (n = 6 each), for total 21 days of treatment. The immobilization stress was induced in rats by putting them in 20 cm × 7 cm plastic tubes for 2 h/day for 21 days. Rats were postorally treated with Salvadora persica at a dose of 900 mg/kg body weight via intragastric intubations. At the end of the test period, hematological and biochemical parameters were determined in blood and serum samples with determination of vital organs weights. The vital organ weights were not significantly affected in stressed rats as compared to control rats. Compared to the control group, the stress treated group showed significances in several hematological parameters, including decreases in WBC, RBC, and PLT counts. Furthermore, in comparison to the control group, the stress group showed significantly increased blood glucose, serum total cholesterol, LDL-cholesterol, and triacylglycerols levels and decreased HDL-cholesterol level. The hematological and biochemical parameters in the stress + extract treated group were approximately similar to control group. The SP extract restored the changes observed following stress treatment. PMID:26221565

Irisin has been proposed to regulate metabolic diseases such as obesity, diabetes or metabolic syndrome which are common comorbidities in psoriasis. The aim of this study was to evaluate the serum irisin level in psoriasis and elucidate possible associations with disease activity, inflammatory or metabolic parameters and topical treatment. Thirty-seven individuals with active plaque-type psoriasis and 15 healthy controls were enrolled. Blood samples were collected before and after two weeks of therapy. Serum irisin concentrations were examined by enzyme-linked immunosorbent assay (ELISA). The results were correlated with psoriasis area and severity index (PASI), body mass index (BMI), inflammatory and biochemical markers, lipid profile and effectiveness of topical treatment. Irisin serum levels were insignificantly increased in psoriatic patients in comparison to the controls (p = 0.38). No significant correlations between investigated adipokine and several indicators of metabolic disorders, nor BMI (p = 0.37) or PASI (p = 0.5) were found. Significant positive correlations with C-reactive protein (CRP) (0.009), lipocalin-2 (p = 0.02), age (p = 0.02) and disease duration (p = 0.008) were noted. After topical treatment, serum irisin level did not significantly change (p = 0.31), despite clinical improvement. Irisin might be a marker of inflammation in psoriatic patients, but may not be a reliable indicator of metabolic conditions, severity of psoriasis nor efficacy of antipsoriatic treatment.

The purpose of this study was to measure the salivary and serum free IGF-1 concentration of patients with anorexia nervosa (AN) in comparison to an average population. A controlled clinical trial was designed for an age- and gender-matched group of 121 AN patients and 77 healthy individuals. A clinical examination was made and blood and salivary samples were taken during the acute stage of AN (BMI measuring free IGF-1 was used. Anorexic patients had significant reductions in salivary unstimulated flow rate (UFR), pH and free IGF-1 levels in their saliva and serum. Significant correlations between serum IGF-1 and BMI; salivary IGF-1 and UFR and pH were detected. Salivary and serum IGF-1 analyses appear to be a reliable biochemical indicator of malnutrition in AN patients. Measurement of salivary IGF-1 levels would allow new perspectives in monitoring AN in its early stages.

Equine serum hepatitis (i.e., Theiler's disease) is a serious and often life-threatening disease of unknown etiology that affects horses. A horse in Nebraska, USA, with serum hepatitis died 65 days after treatment with equine-origin tetanus antitoxin. We identified an unknown parvovirus in serum and liver of the dead horse and in the administered antitoxin. The equine parvovirus-hepatitis (EqPV-H) shares horses using a tetanus antitoxin contaminated with EqPV-H. Viremia developed, the horses seroconverted, and acute hepatitis developed that was confirmed by clinical, biochemical, and histopathologic testing. We also determined that EqPV-H is an endemic infection because, in a cohort of 100 clinically normal adult horses, 13 were viremic and 15 were seropositive. We identified a new virus associated with equine serum hepatitis and confirmed its pathogenicity and transmissibility through contaminated biological products.

Full Text Available Background and Aims. Hyperferritinemia has been related with a wide spectrum of pathologies, including diabetes, cardiovascular disease, neurodegenerative disorders, and metabolic syndrome. The aim of this study was to investigate the association between hyperferritinemia and iron consumption. Methods and Results. Serum ferritin concentration was evaluated in 66 presumed healthy men, along with other clinical and biochemical markers of chronic diseases. A three-day food questionnaire was applied for nutrition information. Hyperferritinemia was a condition found in 13.4% of the volunteers analyzed. Significant correlations were found between serum ferritin concentration and metabolic syndrome parameters (HDL cholesterol, triglycerides, and fasting glucose as well as an increase of the serum ferritin mean value with the number of risk factors of metabolic syndrome. Also, oxidative stress markers (carbonyl groups, AOPP, and glycated hemoglobin, hepatic damage markers (GGT, SGOT, and parameters related to insulin resistance (HOMA, blood insulin, and blood glucose correlate significantly with serum ferritin. Volunteers had an excessive iron intake, principally by bread consumption. Analyses of food intake showed that red meat consumption correlates significantly with serum ferritin. Conclusion. Red meat consumption, metabolic syndrome, and chronic disease markers are associated with hyperferritinemia in a population of Chilean men.

Changes in acetylcholinesterase (AChE, corticosterone and total protein levels were assessed in the serum, brain, liver, lungs and gastrointestinal tract (GIT and the results supported by bioaccumulation data. The biomarkers were chosen as indicators of key physiological functions: AChE for neurotoxicity, corticosterone and total protein levels as indicators of oxidative stress. Toads were exposed to 0.01, 0.02, 0.03 and 0.04 g/L for 28 days. Brain AChE activity reduced by 96% in the highest concentration (0.04 g/L compared to the control brain. Similarly, AChE activities in serum, liver, lungs and GIT tissues (88%, 88%, 87, 87% umg-1 protein respectively were also inhibited in the toads. Corticosterone and total protein levels in the tissues decreased compared to the control. The accumulation results obtained showed accumulation in the tissues (liver>serum>brain> lung>GIT, with a direct relationship between tissue concentration and changes in the biochemical indices. The alterations in all the indices were significantly concentration dependent. The biomarkers described in this study could be useful complementary indices in the risk assessment of diazinon pesticide.

To determine whether high serum bilirubin concentrations interfere with the measurement of serum total protein concentration by refractometry and to assess potential biases among refractometer measurements. Evaluation study. Sera from 2 healthy Greyhounds. Bilirubin was dissolved in 0.1M NaOH, and the resulting solution was mixed with sera from 2 dogs from which food had been withheld to achieve various bilirubin concentrations up to 40 mg/dL. Refractometric total protein concentrations were estimated with 3 clinical refractometers. A biochemical analyzer was used to measure biuret assay-based total protein and bilirubin concentrations with spectrophotometric assays. No interference with refractometric measurement of total protein concentrations was detected with bilirubin concentrations up to 41.5 mg/dL. Biases in refractometric total protein concentrations were detected and were related to the conversion of refractive index values to total protein concentrations. Hyperbilirubinemia did not interfere with the refractometric estimation of serum total protein concentration. The agreement among total protein concentrations estimated by 3 refractometers was dependent on the method of conversion of refractive index to total protein concentration and was independent of hyperbilirubinemia.

To determine effects of the biochemical and cytological properties of blood, serum, and ascites on survival of patients with malignant peritoneal effusion (MPeE), including malignant peritoneal mesothelioma (MPeM) and peritoneal carcinomatosis (PC), we conducted a retrospective study of patients with MPeE and healthy controls. Potential prognostic factors were identified as follows: age, sex, blood neutrophil-to-lymphocyte ratio (NLR), serum parameters, ascites parameters, serum-ascites albumin gradient, and the ascites-serum LDH ratio. Compared to those of the control group, serum albumin levels were significantly lower, and the NLR and serum LDH levels were significantly higher in the MPeE group. Overall survival (OS) was longer in patients with MPeM compared to that in patients with PC. Compared with patients in the MPeM, patients with PC had higher NLRs, ascites glucose levels, serum-ascites albumin gradients, and serum LDH levels. In contrast, their ascites albumin levels and ascites-serum LDH ratios were lower. Univariate analyses indicated that the NLR, serum LDH levels, ascites LDH levels, ascites coenocyte levels, and the ascites coenocyte-to-monocyte ratios affected the OS. Multivariate analyses identified only serum and ascites LDH levels as independent prognostic factors.

Full Text Available Objective: To explore haemato-biochemical and oxidative stress indices due to concomitant tick borne intracellular diseases in dogs presented at Referral Veterinary Polyclinic, Indian Veterinary Research Institute, Bareilly during May 2010 to May 2012. Methods: Microscopy of Giemsa blood smear and ELISA test (SNAP 4D伊 were carried out in suspected cases to confirm haemo-parasitic infection. Blood and serum samples were analyzed for oxidative stress indices and haemato-biochemical changes. All the ailing conditions were recorded to investigate the clinical pattern of concomitant tick borne diseases. Ultrasonographic study was carried out to obtain the hepatic involvement. Results: Examination of 3 650 dogs revealed that 2.77% dog were positive for various tick borne diseases, out of which 21.78% were with concomitant infection. Clinical symptoms were noted with overall mean clinical score of 9.95依0.30. Ultrasonographic examination revealed hepatomegaly, distension of gall bladder, and ascites. Haemato-biochemical evaluation confirmed anaemia, leucopenia, thrombocytopenia, hypoproteinemia, hypoalbuminemia, hyperglobulinemia and hyperbilirubinemia with increased serum alanine amino transferase, alkaline phosphatase and gamma-glutamyl transpeptidase in concomitant infected dogs. The lipid peroxidation level of concomitant infection was significantly higher (P<0.05 than healthy group whereas superoxide dismutase, glutathione-reduced and catalase activity in concomitant infected group were decreased. Conclusions: The severity of infection was more pronounced in dogs harboring Ehrlichia, Babesia and Hepatozoon and the oxidative stress may have a pathophysiological role in concomitant infection in dogs.

Biochemical markers of acute neuronal injury may aid in the diagnosis and management of acute ischemic stroke. Serum samples from the National Institute for Neurological Disorders and Stroke (NINDS) recombinant tissue plasminogen activator Stroke Study were analyzed for the presence of 4 biochemical markers of neuronal, glial, and endothelial cell injury. These biochemical markers, myelin basic protein (MBP), neuron-specific enolase (NSE), S100beta, and soluble thrombomodulin, were studied for an association with initial stroke severity, infarct volume, and functional outcome. In the original NINDS study, serum samples were drawn from all patients on presentation to the Emergency Department and at approximately 2 and 24 hours after initiation of study therapy. In this analysis, stored serum samples were available for 359 patients; 107 patients had samples for all 3 time points. Serum marker concentrations were measured by ELISA techniques. We examined the relation between serum concentrations of each marker and the degree of baseline neurological deficit, functional outcome, and infarct size on computed tomography at 24 hours and the effect of fibrinolytic therapy. Higher 24-hour peak concentrations of MBP, NSE, and S100beta were associated with higher National Institutes of Health Stroke Scale baseline scores (r=0.186, P<0.0001; r=0.117, P=0.032; and r=0.263, P<0.0001, respectively). Higher peak concentrations of MBP and S100beta (r=0.209, P<0.0001; r=0.239, P<0.0001) were associated with larger computed tomography lesion volumes. Patients with favorable outcomes had smaller changes in MBP and S100beta (P<0.05) concentrations in the first 24 hours. Soluble thrombomodulin was not associated with any severity or outcome measure. This study corroborates previous work demonstrating correlations of MBP, NSE, and S100beta with clinical and radiographic features in acute stroke. Despite significantly better outcomes in the tissue plasminogen activator-treated group, we

To improve assessment of dystrophinopathy, the aim of this study was to identify whether serum creatinine (Crn) level reflects disease severity. Biochemical, Vignos score, and genetic data were collected on 212 boys with dystrophinopathy. Serum Crn level had a strong inverse correlation with Vignos score by simple correlation (r = -0.793) and partial correlation analysis after adjustment for age, height, and weight (r = -0.791; both P Becker muscular dystrophy (BMD) patients than Duchenne muscular dystrophy (DMD) patients at ages 4, 5, 7, and 9 yr (all P < 0.0125). After adjusting for age, height, and weight, BMD patients still had a significantly higher serum Crn level than DMD patients (β = 7.140,  t = 6.277,  P < 0.01). Serum Crn level reflected disease severity and may serve as a supplemental index to distinguish DMD from BMD in clinical practice.

Exercise and fitness training programs have attracted the public's attention in recent years. Sports nutrition supplementation is an important issue in the global sports market. In this study, we designed a power exercise training (PET) program with a mouse model based on a strength and conditional training protocol for humans. We tested the effect of supplementation with functional branched-chain amino acid (BCAA)-rich sake protein (SP) to determine whether the supplement had a synergistic effect during PET and enhanced athletic performance and resistance to fatigue. Male ICR mice were divided into three groups (n = 8 per group) for four-week treatment: sedentary controls with vehicle (SC), and PET and PET groups with SP supplementation (3.8 g/kg, PET + SP). Exercise performance was evaluated by forelimb grip strength and exhaustive swimming time as well as changes in body composition and anti-fatigue activity levels of serum lactate, ammonia, glucose, and creatine kinase (CK) after a 15-min swimming exercise. The biochemical parameters were measured at the end of the experiment. four-week PET significantly increased grip strength and exhaustive swimming time and decreased epididymal fat pad (EFP) weight and area. Levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, and uric acid (UA) were significantly increased. PET + SP supplementation significantly decreased serum lactate, ammonia and CK levels after the 15-min swimming exercise. The resting serum levels of AST, ALT, CREA and UA were all significantly decreased with PET + SP. The PET program could increase the exercise performance and modulate the body composition of mice. PET with SP conferred better anti-fatigue activity, improved biochemical profiles, and may be an effective ergogenic aid in strength training.

Objective: To study the changes of serum parathyroid hormone-M, magnesium, and calcium levels and their interrelationships in patients with mild acute pancreatitis (MAP) and severe acute pancreatitis (SAP). Methods: Serum level of PTH-M was measured by means of radioimmunoassay, serum magnesium and calcium levels were determines with automatic biochemical analytical apparatus. Results: 1) Serum levels of PTH-M in acute period and daring recovery in patients with MAP and SAP were not significant different from those in controls (p > 0.05); serum levels of magnesium and calcium in cute period of patients with SAP were significantly lower than those in controls (p<0.01); 2) There was a linear positive correlation between serum levels of PTH-M and serum magnesium in acute-phase of SAP patients, correlation coefficient r = 0.413 (p<0.05). Conclusion: That presence of hypocalcemia in patients with severe acute pancreatitis did not lead to parathyroid hormone-M responsive rise, that might be due to the presence of hypomagnesemia

As a preliminary approach to developing a biochemical assay for detecting humoral regulators of granulocyte maturation in the normal and inglammatory states, studies were carried out on the effects of normal inflammatory sera on the incorporation of 14 C-glucosamine into the glycoproteins of bone marrow granulocytes in vitro. We observed that, relative to normal serum, inflammatory serum had a marked stimulatory effect on 14 C-glucosamine incorporation into these glycoproteins. This property of inflammatory serum reached a maximum at about 8 h after the initiation of inflammation in vivo and preceded the maximum increase in the mitotic activity of granulocyte precursors in the marrow by 18 h. It was also found that normal serum contains both dialyzable and heat-sensitive nondialyzable factors that inhibit 14 C-glucosamine incorporation into bone marrow granulocytes in vitro. Data are presented which indicate that the stimulatory effect of inflammatory serum is most likely due to a nondialyzable factor which is capable of blocking the effect of the inhibitors present in normal serum.

In sublethal gamma-irradiated C. auratus, a sudden decrease of total serum protein concentration and a preferential descent of the low molecular weight gamma-globulin fraction have been observed. These effects are transient and after different latent periods dependent on doses, normal values are recovered, A temporal failure of a vascular permeability regulation system is probably implied. The DMA depolymerization. observed in the intestine indicates the action of radio-induced DNA degradation mechanisms since this effect is independent on doses. (Author) 29 refs

Trace element deficiency and its diagnosis by biochemical criteria

The effect of trace element deficiency on growth of rats and dairy cows is demonstrated using zinc and nickel. The effect of copper deficiency on reproductive performance is shown to be associated with increased death rates of pregnant animals and their foetuses. For the diagnosis of suboptimum states of trace element supply, biochemical criteria are needed. The mere analysis of the trace element content of various body tissues may lead to falase diagnoses because of the often slow response to varying intake and because of interactions with other dietary ingredients affecting absorption and metabolic efficiency of utilization. Thus copper deficiency is associated with a decrease in the serum level of both copper and iron, despite adequate iron intake, and simultaneously with an accumulation of iron in the liver of the animal. Enzymes and hormones containing the essential trace element as an integral constituent may serve as biochemical criteria. A sensitive response to zinc intake is exhibited by the activity of the alkaline phosphatase of serum or bones, and by the activity of the pancreatic carboxypeptidase A, all of which show a significant reaction to deficient intake within two to four days, and perhaps by the biopotency of insulin. Ceruloplasmin responds to the supply of copper. Its biosynthesis in the liver is possible only from copper available for this purpose. Thus, the determination of ceruloplasmin may take account of at least part of the copper available to the body for metabolic functions. Among various criteria, the catalase activity in blood may provide additional information on the state of iron supply. Malate dehydrogenase and glucose-6-phosphate dehydrogenase respond to nickel-deficient intake. Nickel deficiency also involves anaemia due to disorders in iron absorption

The bovine leptospirosis is an economically important zoonotic disease of flood affected areas worldwide, but scarce information is available about its epidemiology in Pakistan. This is a first study on sero-epidemiology of bovine leptospirosis in Pakistan. The objectives of this study were to investigate the sero-prevalence and associated risk factors of bovine leptospirosis in flood affected zone of Punjab, Pakistan. A total of 385 serum samples were randomly collected from four tehsils of district Muzaffargarh, Pakistan. The serum samples were subjected to indirect ELISA for the detection of anti-leptospira antibodies. The overall sero-prevalence of leptospirosis was 30.39%. The prevalence was significantly higher (p0.05) difference among TLC values among sero-positive and sero-negative animals. The serum biochemical profile revealed significant differences (pPakistan, and the disease needs to be explored comprehensively in other parts of the country to sort out solid strategies for its control and eradication.

Around the world, species from the genus Tilia are commonly used because of their peripheral and central medicinal effects; they are prepared as teas and used as tranquilizing, anticonvulsant, and analgesic agents. In this study, we provide evidence of the protective effects of organic and aqueous extracts (100 mg/kg, i.p.) obtained from the leaves of Tilia americana var. mexicana on CCl 4 -induced liver and brain damage in the rat. Protection was observed in the liver and brain (cerebellum, cortex and cerebral hemispheres) by measuring the activity of antioxidant enzymes and levels of malondialdehyde (MDA) using spectrophotometric methods. Biochemical parameters were also assessed in serum samples from the CCl 4 -treated rats. The T. americana var. mexicana leaf extracts provided significant protection against CCl 4 -induced peripheral and central damage by increasing the activity of antioxidant enzymes, diminishing lipid peroxidation, and preventing alterations in biochemical serum parameters, such as the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), γ-globulin (γ-GLOB), serum albumin (ALB), total bilirubin (BB), creatinine (CREA) and creatine kinase (CK), relative to the control group. Additionally, we correlated gene expression with antioxidant activity in the experimental groups treated with the organic and aqueous Tilia extracts and observed a non-statistically significant positive correlation. Our results provide evidence of the underlying biomedical properties of T. americana var. mexicana that confer its neuro- and hepatoprotective effects.

Purpose: To establish the prognostic role of serum enzymatic prostatic acid phosphatase (PAP) in patients treated with palladium ( 103 Pd) and supplemental external beam irradiation (EBRT) for clinically localized, high-risk prostate carcinoma. Methods and Materials: One hundred twenty-four consecutive patients with Stage T2a-T3 prostatic carcinoma were treated from 1992 through 1995. Each patient had at least one of the following risk factors for extracapsular disease extension: Stage T2b or greater (100 patients), Gleason score 7-10 (40 patients), pretreatment prostate specific antigen (PSA) > 15 ng/ml (32 patients), or elevated serum PAP (25 patients). Patients received 41 Gy conformal EBRT to a limited pelvic field, followed 4 weeks later by a 103 Pd boost (prescription dose 80 Gy). Biochemical failure was defined as a PSA greater than 1 ng/ml (normal < 4 ng/ml). Results: The overall, actuarial freedom from biochemical failure at 4 years after treatment was 79%. In Cox-proportional hazard multivariate analysis, the strongest predictor of failure was elevated pretreatment acid phosphatase (p = 0.02), followed by Gleason score (p = 0.1), and PSA (p = 0.14). Conclusion: PAP was the strongest predictor of long-term biochemical failure. It may be a more accurate indicator of micrometastatic disease than PSA, and as such, we suggest that it be reconsidered for general use in radiation-treated patients

Total blood homocysteine (Hcys) and folate levels have been investigated in association with cognitive dysfunction in healthy but not in multimorbid elderly patients. We hypothesized that total serum Hcys is an adequate marker to identify multimorbid elderly patients with cognitive dysfunction assessed by the Short Cognitive Performance Test (SKT) and Mini-Mental State Examination (MMSE). Cross-sectional study. The study center was an acute geriatric hospital. A total of 189 multimorbid elderly patients were recruited. Cognitive dysfunction was determined according to the SKT and MMSE. Biochemical parameters (Hcys, folate, vitamin B12, hemoglobin), nutritional status (BMI, Mini Nutritional Assessment, nutritional intake), and activities of daily living were assessed. According to the SKT, 25.4% of patients showed no cerebral cognitive dysfunction, 21.2% had suspected incipient cognitive dysfunction, 12.7% showed mild cognitive dysfunction, 9.0% had moderate cognitive dysfunction, and 31.7% of patients were demented. The median plasma Hcys value was elevated by approximately 20% in multimorbid elderly patients, independent of cognitive dysfunction. Serum folate and vitamin B12 concentrations were within normal ranges. We did not find significant differences in nutritional status, activities of daily living, numbers of diseases or medications, or selected biochemical parameters between the SKT groups. Elevated serum Hcys levels with normal plasma folate and vitamin B12 concentrations were observed in multimorbid elderly patients. The plasma Hcys level did not appear to be an important biological risk factor for cognitive dysfunction in multimorbid geriatric patients.

A protein that has 2 subunits with molecular weight of 35,000 and 23,000 was detected in serum of cattle with hepatic lipidosis (fatty liver). The protein was purified from serum obtained from a cow with fatty liver, and was identified as haptoglobin, which is known to have hemoglobin-binding capacity and to be an acute-phase protein. To assess the relevance of haptoglobin in fatty liver, cattle were classified in 3 groups (healthy control, haptoglobin-positive, and haptoglobin-negative); liver triglyceride content and several serum biochemical variables were evaluated for the 3 groups. Compared with the control and haptoglobin-negative cattle, haptoglobin-positive cattle had significantly (P less than 0.01) higher liver triglyceride content, serum bilirubin concentration, and aspartate transaminase activity. Serum haptoglobin concentration was high in slaughter cattle (27 of 40 cattle tested), particularly in cows (20/28).

Fischer, H P; Lankes, G

1991-01-01

The microanatomic organization of focal nodular hyperplasia (FNH) of the liver was analyzed to obtain information about the histogenesis of this tumor-like lesion. All of the 11 examples of FNH studied showed subdivision into multiple pseudolobules, which were characterized by fibrovascular and ductular areas radiating from perilobular septa, and an expanding periphery of normal appearing hepatocytes. Immunohistochemical analysis showed continuous transitions from normal hepatocytes in the periphery of the pseudolobules, which expressed only the keratins 8 and 18, to small hepatocytes and ductular aggregates in the center of the pseudolobules, both of which also expressed the keratins 7 and 19. Ductular metaplasia of hepatocytes was always accompanied by sinusoidal endothelial cells stained by the endothelial markers BMA 120, M 616, and by an increase in collagenous fibers especially of type III. Further development of this fibrovascular and ductular transformation lead to subdivision of the involved pseudolobules. The pseudolobules had similar mean sizes, irrespective of their site in the periphery or the center of the FNHs, showing that proliferation, fibrovascular and ductular transformation and subdivision of these micronodules are a basic histogenetic phenomenon in FNH. The findings indicate that local changes in the interrelations between liver epithelial and mesenchymal cells influence substantially the abnormal but nevertheless regulated growth of liver parenchyma which gives rise to FNH.

The role of progranulin in individuals with metabolic syndrome is not exactly clear.We aimed to assess the serum level of progranulin in type 2 diabetic patients with and without metabolic syndrome and compare them with healthy controls. The study included 60 patients with type 2 diabetes and 30 healthy individuals as control groups. Biochemical parameters and progranulin levels were determined. Subjects with metabolic syndrome showed significantly higher levels of triglyceride, waist circumference, BMI, systolic and diastolic blood pressure than subjects without metabolic syndrome and the control groups, while HDL-cholesterol level was significantly lower in subjects with metabolic syndrome. Fasting blood sugar was significantly higher in type 2 diabetic patients than in the control groups. Serum level of progranulin was slightly increased in subjects with metabolic syndrome. Serum progranulin level had no significant relationship with metabolic syndrome components. Serum progranulin was also not dependent on cardiometabolic risk factors for subjects with metabolic syndrome, but it could be considered for the management of type 2 diabetes mellitus. Further studies are recommended to explain the effect of progranulin on the pathogenesis of metabolic risk factors.

High serum albumin levels during ischemic stroke (IS) decrease the risk of a poor outcome. This study aimed to determine whether serum albumin levels within the first days after IS correlate with radiological and biochemical markers of brain tissue damage. Fifty-six IS patients were enrolled into the study. Neurological examinations were based on the National Institute of Health Stroke Scale. Serum albumin levels and S100BB were evaluated using commercially available ELISA kits. The albumin decrease index (ADI) was calculated as the difference between serum albumin levels measured on days 1 and 10 of IS. All parameters were estimated on the 1st, 3rd, 5th, and 10th days of IS, and the volume of ischemic focus was measured on the 10th day. Mean serum albumin levels were decreased during acute IS. There were correlations between the ADI and mean S100BB serum levels (r = 0.36, p albumin levels during the acute phase of IS corresponds to a worse neurological state as a result of a large ischemic focus with intense catabolic processes.

Full Text Available The present investigation was carried out to evaluate the biochemical effect of Withania somnifera Linn. Solanaceae, commonly known as ashwagandha on adjuvant induced arthritic rats. Results were compared to Indomethacin, a non steroidal anti-inflammatory drug. Arthritis was induced by an intra dermal injection of Complete Freund’s Adjuvant (0.1 ml into the right hind paw of Wistar albino rats. Withania somnifera root powder (1000 mg/kg/day and Indomethacin (3 mg/kg/day were orally administered for 8 days (from 11th to 18th day after adjuvant injection. After the experimental period, all the animals were sacrificed and serum, liver and spleen samples were collected for further biochemical analysis. A significant increase in the activities of gluconeogenic enzymes, tissue marker enzymes, blood glucose level, WBC, platelet count, erythrocyte sedimentation rate, and acute phase proteins (hyaluronic acid, fibrinogen and ceruloplasmin was observed in adjuvant-induced arthritic rats, whereas the activities of glycolytic enzymes, body weight, levels of hemoglobin, RBC count, and packed cell volume were found to be decreased. These biochemical alterations observed in arthritic animals were ameliorated significantly after the administration of Withania somnifera root powder (1000 mg/kg/b.wt and Indomethacin (3 mg/kg/b.wt. Our results suggest that Withania somnifera root powder is capable of rectifying the above biochemical changes in adjuvant arthritis and it may prove to be useful in treating rheumatoid arthritis.

To evaluate the association between serum uric acid and obesity among university students who participated in routine health screening in 2013. In this cross-sectional study, 3529 subjects were analyzed. Obesity categories were classified by BMI levels references in China. And serum uric acid levels were classified by serum uric acid quartiles. Two-sample T-test and Wilcoxon Rank sum test were used to compare age, biochemical and anthropometric parameters of subjects of two genders. Rank correlation used to analyze relationship between serum uric acid and obesity. There were 1285 males (mean age, 19.8 ± 1.3 years) and 2244 females (mean age, 19.9 ± 1.3 years) in this study. Association between 2nd serum uric acid quartile and normal in male are significant and coefficient was 0.519. The 3rd serum uric acid quartile and normal in female was associated significantly (r = 0.173, p = 0.010). And associations between overweight and 3rd and 4th serum uric acid quartiles in female were significant (r = 0.128, p = 0.038 in 1st quartile and r = 0.282, p = 0.004 in 4th quartile). The 4th serum uric acid quartile and Obesity in two gender groups were significantly associated (r = 0.291, p = 0.000 in male and r = 0.484, p = 0.001 in female). High serum uric acid was positively associated with obesity in overweight and obesity group. However, the association was weak between two variables because serum uric acid influenced obesity with other related factors together. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

Full Text Available Exercise and fitness training programs have attracted the public’s attention in recent years. Sports nutrition supplementation is an important issue in the global sports market. Purpose: In this study, we designed a power exercise training (PET program with a mouse model based on a strength and conditional training protocol for humans. We tested the effect of supplementation with functional branched-chain amino acid (BCAA-rich sake protein (SP to determine whether the supplement had a synergistic effect during PET and enhanced athletic performance and resistance to fatigue. Methods: Male ICR mice were divided into three groups (n = 8 per group for four-week treatment: sedentary controls with vehicle (SC, and PET and PET groups with SP supplementation (3.8 g/kg, PET + SP. Exercise performance was evaluated by forelimb grip strength and exhaustive swimming time as well as changes in body composition and anti-fatigue activity levels of serum lactate, ammonia, glucose, and creatine kinase (CK after a 15-min swimming exercise. The biochemical parameters were measured at the end of the experiment. Results: four-week PET significantly increased grip strength and exhaustive swimming time and decreased epididymal fat pad (EFP weight and area. Levels of aspartate aminotransferase (AST, alanine aminotransferase (ALT, creatinine, and uric acid (UA were significantly increased. PET + SP supplementation significantly decreased serum lactate, ammonia and CK levels after the 15-min swimming exercise. The resting serum levels of AST, ALT, CREA and UA were all significantly decreased with PET + SP. Conclusion: The PET program could increase the exercise performance and modulate the body composition of mice. PET with SP conferred better anti-fatigue activity, improved biochemical profiles, and may be an effective ergogenic aid in strength training.

Measuring the level of serum lipase has been used for the clinical diagnosis of acute pancreatitis. Reports showed that the serum lipase level increased in patients of clinical renal failure. In this study, we aimed to measure the change of serum lipase levels in chronic kidney diseases and determine whether it could serve as a clinical laboratory index for clinical renal failure diagnosis. Materials: The OLYMPUS AU5400 automatic biochemical analyzer was used to determine the serum levels of lipase and creatinine. The study included 120 cases in the clinical renal failure group, 76 cases in the nephrotic syndrome group, 81 cases in the chronic nephritis group, and 80 healthy controls from our hospital volunteers in the same period. We then compared the lipase levels and conducted statistical analyses among these groups. The serum lipase levels were 15.3 U/L, 79.8 U/L, 45.1 U/L, and 51.0 U/L in the normal control, clinical renal failure, nephrotic syndrome, and chronic nephritis groups, respectively. The lipase levels in the groups with diseases were significantly different compared with that of the normal control group (p renal failure group was significantly higher than that of the nephrotic syndrome group and chronic nephritis group (p chronic nephritis group (p > 0.05) was observed. Moreover, an association of the serum lipase with disease progression was observed in the study. Serum lipase is an effective serological index which can reflect the clinical changes in the clinical renal failure and tends to increase through the progression of renal dysfunction.

E-selectin is expressed by the activated endothelium and its plasma levels are increased in patients with systemic sclerosis. Eighteen patients fulfilling the American Rheumatism Association criteria for systemic sclerosis, 15 females and 3 males, 42-70 years old, 9 with diffuse and 9 with limited forms, were sequentially recruited for this study. Serum E-selectin levels were determined by commercially available ELISA and their association with nailfold capillaroscopic abnormalities was investigated. Nailfold capillaries were analyzed by 16X magnification wide-field capillaroscopy. Two parameters on capillaroscopy were used to correlate to serum E-selectin: deletion and ectasia. Data were analyzed statistically by the Student t-test and Spearman correlation. Two-tailed P values below 0.05 were considered significant. E-selectin range was 38 to 200 ng/ml (80 +/- 39.94). There was a correlation between serum E-selectin levels and the deletion capillaroscopic score (r = 0.50, P capillaroscopy. The stronger correlation of deletion score in capillaroscopy in early disease suggests that serum E-selectin levels might be a useful biochemical marker of disease activity in systemic sclerosis.

Full Text Available Background and Purpose. Dry needling is an effective therapy for the treatment of pain associated with myofascial trigger point (MTrP. However, the biochemical effects of dry needling that are associated with pain, inflammation, and hypoxia are unclear. This study investigated the activities of β-endorphin, substance P, TNF-α, COX-2, HIF-1α, iNOS, and VEGF after different dosages of dry needling at the myofascial trigger spots (MTrSs of a skeletal muscle in rabbit. Materials and Methods. Dry needling was performed either with one dosage (1D or five dosages (5D into the biceps femoris with MTrSs in New Zealand rabbits. Biceps femoris, serum, and dorsal root ganglion (DRG were sampled immediately and 5 d after dry needling for β-endorphin, substance P, TNF-α, COX-2, HIF-1α, iNOS, and VEGF immunoassays. Results. The 1D treatment enhanced the β-endorphin levels in the biceps femoris and serum and reduced substance P in the biceps femoris and DRG. The 5D treatment reversed these effects and was accompanied by increase of TNF-α, COX-2, HIF-1α, iNOS, and VEGF production in the biceps femoris. Moreover, the higher levels of these biochemicals were still maintained 5 d after treatment. Conclusion. Dry needling at the MTrSs modulates various biochemicals associated with pain, inflammation, and hypoxia in a dose-dependent manner.

Eighty Dorper × thin-tailed Han cross-bred non-castrated male lambs [mean body weight (BW), 25.87 ± 1.06 kg] were randomly allocated to one of five different concentrations of slow-release urea (urea phosphate, UP). The feed consisted of an equal amount of concentrate diet and roughage; the concentrate feed was formulated to be isoenergetic and isonitrogenic and contained 0%, 1%, 2%, 4% and 8% UP (UP0.0, UP1.0, UP2.0, UP4.0 and UP8.0, respectively) as a replacement for soya bean meal. Feed intake, BW, average daily gain (ADG), feed utilisation efficiency (FUE), absolute and relative organ weights and biochemical and histopathological parameters were measured. Feed intake, BW, ADG and FUE significantly decreased in the group receiving UP8.0 (p  0.05). Quadratic equations were developed between the UP dosage in the concentrate feed and ADG or FUE (r 2  = 0.973 for ADG and r 2  = 0.761 for FUE) to determine the appropriate dosage of UP given the desire to maximise either ADG or FUE, the appropriate dosage (feed concentration) was calculated as 2.01% UP to achieve the greatest ADG or 2.13% UP to achieve the best FUE. The relative weight of the liver (% BW) in the UP2.0 groups was significantly greater than that of UP0.0 (p  0.05). The UP8.0 treatment significantly increased serum phosphorus levels (p < 0.05) and decreased the levels of alkaline phosphatase, glucose and calcium (Ca) compared with the lower UP dosage (p < 0.05). No histopathological differences were found in either hepatic tissues or renal tissues among treatments. Dietary UP as a replacement for soya bean in concentrate feeds for mutton sheep should not exceed 4%, as higher dosing may cause malnutrition and mineral disorders.

Full Text Available The role of inflammation being minimal in the pathogenesis of type 2 diabetes mellitus (T2DM in nonobese patients; the aim of the study was to investigate the role of adenosine deaminase (ADA and see its association with diabetes mellitus. The preliminary case control study comprised of 56 cases and 45 healthy controls which were age and sex matched. 3 mL venous blood samples were obtained from the patients as well as controls after 8–10 hours of fasting. Serum ADA and routine biochemical parameters were analyzed. Serum ADA level was found significantly higher among nonobese T2DM subjects with respect to controls (38.77±14.29 versus 17.02±5.74 U/L; P<0.0001. Serum ADA level showed a significant positive correlation with fasting plasma glucose (r=0.657; P<0.0001 level among nonobese T2DM subjects, but no significant correlation was observed in controls (r=-0.203; P=0.180. However, no correlation was observed between serum ADA level compared to BMI and HbA1c levels. Our study shows higher serum ADA, triglycerides (TG and fasting plasma glucose (FPG levels in nonobese T2DM patients, and a strong correlation between ADA and FPG which suggests an association between ADA and nonobese T2DM subjects.

Selected anthropometric and biochemical measurements were also determined. A significant difference (P abdominal fat volumes, leptin, resistin, adiponectin and waist circumference. Waist circumferences were measured by tape and MRI. Findings revealed that MRI-measured fat volumes were different between males and females and had a significant (P fat volumes were found to correlate moderately with interleukin-6 and weakly with cholesterol, serum triglyceride and low-density lipoprotein. Except for cholesterol, all measured biochemical variables and abdominal fat volumes in the current study were significantly associated with body mass index. All anthropometric and biochemical parameters showed weak-to-strong associations with the MRI-measured fat volumes. Abdominal fat distribution was different between males and females and their correlations with some lipid profiles were found to be sex dependent. These findings revealed that MRI can be used as an alternative tool for obesity assessment. Copyright © 2016 Southern Society for Clinical Investigation. Published by Elsevier Inc.

Sixty four ostrich birds from the breeding flock in Nuclear Research Center, AEA, Egypt (March 2008) aged from one week old until post-sexual maturity were used to determine blood biochemical baseline values. Blood was drawn from each bird of each group and blood hematological parameters such as total red blood cells (RBC), total white blood cells (WBC), hemoglobin concentration (Hb) and packed cell volume (PCV) percentage were determined. In addition, blood serum was separated to evaluate the concentrations of serum total protein (TP), albumin (Alb), globulin (Glob), calcium (Ca) and phosphorus (P). Liver function such a serum aspartate transaminase (AST) and alanine transaminase (ALT) were determined. Also, kidney function such as serum urea (U), creatinine (Cr) and uric acid (UA) were measured. Serum total cholesterol (Chol), triglycerides (Trg) and serum triiodothyronine (T 3 ) were determined. The results showed that:1- Hb and RBC were positively correlated with age and were significantly increased in males than females. There was non-significant difference in RBC between laying and non-laying birds, but Hb concentration was significantly increased in non-laying than laying birds. 2- WBC count was decreased in young birds than adult birds and it was significantly increased in adult females than males and in laying than non-laying birds. 3- PCV was positively correlated by age and it was increased in males than females and in non-laying than laying birds. 4- The concentrations of serum TP, Alb, Glob, Ca and P were increased as age increased and were increased in males than females and in non-laying than laying birds. 5- Serum T 3 hormone was positively correlated with age until two years old then decreased significantly. It was significantly increased in adult male than females and in laying than non-laying birds.6- Kidney function such as serum U, Cr and UA were increased in young than adult birds. It was decreased in adult females than males while it

Full Text Available The current study was designed to probe pathological effects of colistin in growing broilers. One hundred twenty day-old broiler chicks were divided into six equal groups A-F. These birds were injected colistin sulphate, 0, 5, 10, 20, 40 and 80 mg/kg BW respectively through intramuscular route. The different serum-biochemical parameters including total protein, albumen, globulin, ALT, AST, LDH, GGT, creatinine and BUN were determined at day 21 and 42 of experiment. The hematological parameters including RBC, WBC, PCV and Hb were determined twice. The serum total protein values were significantly higher in group E as compared with control group. At day 42 groups, C-E had significantly lower albumen values as compared to group A. The similar pattern was observed in globulin values. The creatinine & urea was also found significantly higher in group D and E at day 21 of experiment, while at day 42 all the groups having significantly higher urea level in comparison with group A indicating nephrotoxic effect of colistin. The serum enzymes including ALT and AST were significantly higher in group D & E as compared with group A, which is an indication of liver damage. The LDH and GGT values showed significantly increasing trend in experimental groups compared with control. The erythrocytes and leucocytes count were significantly higher in control and low dose groups as compared with higher colistin dose groups. It is concluded that lavish parenteral administration of colistin resulted in increased levels of hepato-renal serum indicators and lower values of hematological parameters.

Measurements of bone biochemical markers are increasingly being used to evaluate the state of bone turnover in the management of bone metabolic diseases, especially osteoporosis. However, changes in the bone turnover rate vary with age. The aim of this study was to establish the laboratory reference range of serum bone-specific alkaline phosphatase (sBAP), serum type I collagen cross-linked C-terminal telopeptide (sCTx), and urine CTx (uCTx), based on values from 665 healthy Chinese women aged 20-80 years. We measured the levels of sBAP, sCTx, serum alkaline phosphatase (sALP), and uCTx and evaluated the age-related changes and their relationship with bone mineral density (BMD) in the anteroposterior (AP) lumbar spine, hip, and left forearm. We found significant correlations between biochemical markers and age, with coefficients of determination (R (2)) of 0.358 for sBAP, 0.126 for sCTx, 0.125 for uCTx, and 0.336 for sALP. The net changes in different biochemical markers were inversely correlated with the rates of BMD loss in the AP lumbar spine. After correction for age, body weight, and height, the levels of the markers had significant negative correlations with the BMD of the AP lumbar spine, femoral neck, and ultradistal forearm. All four biochemical markers had the highest negative correlation with BMD of the AP lumbar spine (partial correlation coefficients of -0.366, -0.296, -0.290, and -0.258 for sBAP, sCTx, uCTx, and sALP, respectively). The mean and SD values of these markers in premenopausal and postmenopausal women with normal BMD values were used as the normal reference ranges. The reference ranges of sBAP, sCTx, and uCTx for pre- vs postmenopausal women were 17.3 +/- 6.23 vs 18.9 +/- 7.52 U/l, 3.18 +/- 1.49 vs 3.23 +/- 1.57 nmol/l, and 15.5 +/- 11.4 vs 16.2 +/- 12.4 nM bone collagen equivalents/mM urinary creatinine, respectively. Levels of the bone formation marker (sBAP) and bone resorption markers (sCTx, uCTx) increased rapidly in women with

To determine whether or not there was a significant difference between the methods of centrifugation (CF) and multiple-pass hemoconcentration (MPH) of the residual cardiopulmonary-bypass volume in relation to biochemical measurements and patient outcomes. Prospective, randomized, and controlled. Conducted at a western Canadian tertiary care hospital. Consisted of 61 consecutive male and female patients from ages 40 to 80 who were scheduled for cardiac surgery with cardiopulmonary bypass. Either the centrifugation or multiple-pass hemoconcentration method was used to process the residual blood from the cardiopulmonary bypass circuit. The 12-hour postoperative levels of serum hemoglobin were not significantly different in the centrifugation group as compared to the multiple-pass hemoconcentration group. However, the serum levels of total protein and albumin were significantly higher in the multiple-pass hemoconcentration group as compared to the centrifugation group. Additionally, after 12-hours postoperatively, the serum fibrinogen and platelet counts were significantly higher in the multiple-pass hemoconcentration group as compared to those of the centrifugation group. The allogeneic product transfusion index and the chest-tube blood drainage indices were lower in the multiple-pass hemoconcentration group as compared to the centrifugation group. Although the CF method provided a product in a shorter turnaround time, with consistent clearance of heparin, the MPH method trended towards enhanced biochemical and clinical patient outcomes over the 12-hour postoperative period.

While the molecular mechanisms underlying postmortem change have been exhaustively investigated, the establishment of an objective and reliable means for estimating postmortem interval (PMI) remains an elusive feat. In the present study, we exploit low molecular weight metabolites to estimate postmortem interval in mice. After sacrifice, serum and muscle samples were procured from C57BL/6J mice (n = 52) at seven predetermined postmortem intervals (0, 1, 3, 6, 12, 24, and 48 h). After extraction and isolation, low molecular weight metabolites were measured via gas chromatography/mass spectrometry (GC/MS) and examined via semi-quantification studies. Then, PMI prediction models were generated for each of the 175 and 163 metabolites identified in muscle and serum, respectively, using a non-linear least squares curve fitting program. A PMI estimation panel for muscle and serum was then erected which consisted of 17 (9.7%) and 14 (8.5%) of the best PMI biomarkers identified in muscle and serum profiles demonstrating statistically significant correlations between metabolite quantity and PMI. Using a single-blinded assessment, we carried out validation studies on the PMI estimation panels. Mean ± standard deviation for accuracy of muscle and serum PMI prediction panels was -0.27 ± 2.88 and -0.89 ± 2.31 h, respectively. Ultimately, these studies elucidate the utility of metabolomic profiling in PMI estimation and pave the path toward biochemical profiling studies involving human samples.

Biochemical Markers in Neurocritical Care

Full Text Available During the past two decades, a variety of serum or cerebrospinal fluid (CSF biochemical markers in daily clinical practice have been recommended to diagnose and monitor diverse diseases or pathologic situations. It will be essential to develop a panel of biomarkers, to be suitable for evaluation of treatment efficacy, representing distinct phases of injury and recovery and consider the temporal profile of those. Among the possible and different biochemical markers, S100b appeared to fulfill many of optimized criteria of an ideal marker. S100b, a cytosolic low molecular weight dimeric calciumbinding protein from chromosome 21, synthesized in glial cells throughout the CNS, an homodimeric diffusible, belongs to a family of closely related protein, predominantly expressed by astrocytes and Schwann cells and a classic immunohistochemical marker for these cells, is implicated in brain development and neurophysiology. Of the 3 isoforms of S-100, the BB subunit (S100B is present in high concentrations in central and peripheral glial and Schwann cells, Langerhans and anterior pituitary cells, fat, muscle, and bone marrow tissues. The biomarker has shown to be a sensitive marker of clinical and subclinical cerebral damage, such as stroke, traumatic brain injury, and spinal cord injury. Increasing evidence suggests that the biomarker plays a double function as an intracellular regulator and an extracellular signal of the CNS. S100b is found in the cytoplasm in a soluble form and also is associated with intracellular membranes, centrosomes, microtubules, and type III intermediate filaments. Their genomic organization now is known, and many of their target proteins have been identified, although the mechanisms of regulating S100b secretion are not completely understood and appear to be related to many factors, such as the proinflammatory cytokines, tumor necrosis factor alpha (TNF-a, interleukin (IL-1b, and metabolic stress.

Full Text Available Assessment of foetal maturity had been proven of value in evaluating the foetal condition. Accurate assessment of foetal maturity is essential for the proper timing of delivery in various risk pregnancies. Amniotic Fluid analysis for foetal maturity had been of proven value. In the present study, study of biochemical parameters in amniotic fluid in respect of Creatinine, Uric Acid, Urea, Total Proteins, and Electrolytes i.e. Sodium, Potassium and Chloride has been done, along with Serum Electrolytes. Standard methodologies were adopted. The observations in the present study correlated with the works of Chadick et al and Pitkin and Zwirek. The levels of Creatinine, Uric Acid and Urea in Amniotic Fluid showed elevation, while Total Proteins and Serum Sodium showed a decline, as gestation progressed. The Serum and Amniotic Fluid Potassium and Chloride levels remain almost constant throughout the pregnancy. Thus, it is observed that the use of multiple parameters is desirable for accurate assessment of foetal maturity.

This study carried out to investigate the possible role of whey protein protein concentrate in ameliorating some biochemical disorders induced in gamma irradiated male rats. Forty eight male albino rats were divided into four equal groups: Group 1 fed on normal diet during experimental period. Group 2 where the diet contain 15 % whey protein concentrate instead of soybean protein . Group 3 rats were exposed to whole body gamma radiation with single dose of 5 Gy and fed on the normal diet. Group 4 rate exposed to 5 Gy then fed on diet contain 15 % whey protein concentrate, the rats were decapitated after two and four weeks post irradiation. Exposure to whole body irradiation caused significant elevation of serum ALT, AST, glucose, urea, creatinine and total triiodothyronine with significant decrease in total protein, albumin and thyroxin.

Acromegaly is a rare, slowly progressive disorder resulting from excessive growth hormone (GH) production by a pituitary somatotroph tumor. The objective of this study was to examine acromegaly treatment outcomes during long-term care at a specialized pituitary center in patients presenting with lack of biochemical control. Data came from an acromegaly registry at the Cedars-Sinai Medical Center Pituitary Center (center). Acromegaly patients included in this study were those who presented biochemically-uncontrolled for care at the center. Biochemical control status, based on serum insulin-like growth factor-1 values, was determined at presentation and at study end. Patient characteristics and acromegaly treatments were reported before and after presentation by presenting treatment status and final biochemical control status. Data on long-term follow-up were recorded from 1985 through June 2013. Seventy-four patients presented uncontrolled: 40 untreated (54.1%) and 34 (45.9%) previously-treated. Mean (SD) age at diagnosis was 43.2 (14.7); 32 (43.2%) were female patients. Of 65 patients with tumor size information, 59 (90.8%) had macroadenomas. Prior treatments among the 34 previously-treated patients were pituitary surgery alone (47.1%), surgery and medication (41.2%), and medication alone (11.8%). Of the 40 patients without prior treatment, 82.5% achieved control by study end. Of the 34 with prior treatment, 50% achieved control by study end. This observational study shows that treatment outcomes of biochemically-uncontrolled acromegaly patients improve with directed care, particularly for those that initially present untreated. Patients often require multiple modalities of treatment, many of which are offered with the highest quality at specialized pituitary centers. Despite specialized care, some patients were not able to achieve biochemical control with methods of treatment that were available at the time of their treatment, showing the need for additional

Full Text Available Abstract Background Exaggerated postprandial spikes in blood glucose and lipids induce proportional increases in oxidative stress, which acutely trigger impairment endothelial, inflammation and increased risk of future cardiovascular events. In this research, we have investigated acute effects of vinegar intake on some of the biochemical atherosclerosis risk factors in high cholesterol fed rabbits to see if we can find a probable protective value for it. Methods The rabbits were randomly divided into four groups: normal diet, high cholesterol diet (%1cholesterol, %1 cholesterol with 5 ml vinegar (low dose, %1 cholesterol with 10 ml vinegar (high dose. After fasting for 12-15 hours, blood samples were taken to determine baseline values. Three hours after feeding, blood samples were collected again to investigate acute effects of vinegar intake on the measured factors. Results Using high-dose vinegar with cholesterolemic diet caused significant reduce in LDL-cholesterol (LDL-C, oxidized-LDL (ox-LDL, malondialdehyde (MDA, total cholesterol (TC and apolipoprotein B (ApoB in comparison with hypercholesterolemic diet. Consumption low-dose vinegar with cholesterolemic diet induced a significant decrease in fibrinogen and glucose compared to hypercholesterolemic diet. Level of serum nitrite, nitrate, triacylglycerol (TAG, HDL-cholesterol (HDL-C, apolipoprotein A (ApoA, serum glutamic pyruvic transaminase (SGPT, serum glutamic oxaloacetate transaminase (SGOT and C-reactive protein (CRP were not significantly difference in low and high doses vinegar with cholesterolemic diet compared to hypercholesterolemic diet. A significant difference was observed for LDL-C, ApoB100 and TC between low and high doses vinegar. Conclusion This study suggest that vinegar, might have some acute effects on biochemical risk factors of atherosclerosis and a probable protective value can be considered for its postprandial use.

Serum phosphate concentrations usually show great variability in patients with advanced chronic kidney disease (ACKD) not on dialysis. Diuretics treatment can have an influence over the severity of mineral-bone metabolism alterations related to ACKD, but their effect on serum phosphate levels is less known. This study aims to determine whether diuretics are independently associated with serum phosphate levels, and to investigate the mechanisms by which diuretics may affect phosphate metabolism. 429 Caucasian patients with CKD not on dialysis were included in this cross-sectional study. In addition to conventional serum biochemical measures, the following parameters of renal phosphate excretion were assessed: 24-hours urinary phosphate excretion, tubular maximum phosphate reabsorption (TmP), and fractional excretion of phosphate (FEP). 58% of patients were on treatment with diuretics. Patients on diuretics showed significantly higher mean serum phosphate concentration (4.78 ± 1.23 vs. 4.24 ± 1.04 mg/dl; Pdiuretics. By multivariate linear and logistic regression, significant associations between diuretics and serum phosphate concentrations or hyperphosphataemia remained after adjustment for potential confounding variables. In patients with the highest phosphate load adjusted to kidney function, those treated with diuretics showed significantly lower FEP than those untreated with diuretics. Treatment with diuretics is associated with increased serum phosphate concentrations in patients with ACKD. Diuretics may indirectly interfere with the maximum renal compensatory capacity to excrete phosphate. Diuretics should be considered in the studies linking the relationship between serum phosphate concentrations and cardiovascular alterations in patients with CKD.

Full Text Available The effects of different dietary electrolyte balance (DEB on growth performance, nitrogen (N metabolism and some blood biochemical parameters were investigated in 2 to 3 months old growing rabbits. A total of 150 growing rabbits of 2 months age were randomly divided into five groups according to average body weight, with 30 rabbits in each group. The DEB levels of the five experimental diets were −154, −3.16, +201, +347, and +500 meq/kg of dry matter (DM, respectively. There was a 7-d adaptation period and a 23-d experimental period. The results showed that the DEB levels had a quadratic affect on the average daily feed intake (ADFI (p<0.001. The greatest ADFI was achieved when the DEB level was +201 meq/kg DM. Fecal N (FN content linearly decreased (0.047, while digestible N (DN, retained N (RN, efficiency of intake N converted into digestible N (DN/IN and the efficiency of intake N converted into retained N (RN/IN linearly increased with the DEB increase (0.020, 0.004, 0.021, and 0.049, respectively. Serum phosphorus (P ion content linearly increased with the DEB increase (p = 0.036. The DEB had a quadratic relationship with serum anion gap (AG (p = 0.002 and serum parathyroid hormone (PTH content (p = 0.016. The DEB levels quadratically affected base excess (BE in the plasma (p<0.001. In conclusion, the DEB unaffected growth performance but affected feed intake, N metabolism and some blood biochemical parameters of growing rabbits.

Background and Aims Malnutrition is a leading cause of morbidity and mortality in cirrhosis. There is no consensus as to the optimal approach for identifying malnutrition in end-stage liver disease. The aim of this study was to measure biochemical, serologic, hormonal, radiographic, and anthropometric features in a cohort of hospitalized cirrhotic patients to characterize biomarkers for identification of malnutrition. Design In this prospective observational cohort study, 52 hospitalized cirrhotic patients were classified as malnourished (42.3%) or nourished (57.7%) based on mid-arm muscle circumference malnutrition. Results Subjects with and without malnutrition differed in several key features of metabolic phenotype including wet and dry BMI, skeletal muscle index, visceral fat index and HOMA-IR. Serum leptin levels were lower and INR was higher in malnourished subjects. Serum leptin was significantly correlated with HOMA-IR, wet and dry BMI, mid-arm muscle circumference, skeletal muscle index, and visceral fat index. Logistic regression analysis revealed that INR and log-transformed leptin were independently associated with malnutrition. Conclusions Low serum leptin and elevated INR are associated with malnutrition in hospitalized patients with end-stage liver disease. PMID:27583675

Full Text Available Abstract Background Firefighters are frequently exposed to significant concentrations of hazardous materials including heavy metals, aldehydes, hydrogen chloride, dichlorofluoromethane and some particulates. Many of these materials have been implicated in the triggering of several diseases. The aim of the present study is to investigate the effect of fire smoke exposure on serum heavy metals and possible affection on iron functions compounds (total iron binding capacity, transferrin saturation percent, ferritin, unsaturated iron-binding capacity blood hemoglobin and carboxyhemoglobin,. Subjects and methods Two groups of male firefighter volunteers were included; the first included 28 firefighters from Jeddah city, while the second included 21 firefighters from Yanbu city with an overall age rang of 20–48 years. An additional group of 23 male non-firefighters volunteered from both cities as normal control subjects. Blood samples were collected from all volunteer subjects and investigated for relevant parameters. Results The results obtained showed that there were no statistically significant changes in the levels of serum heavy metals in firefighters as compared to normal control subjects. Blood carboxyhemoglobin and serum ferritin were statistically increased in Jeddah firefighters, (p Conclusion Such results might point to the need for more health protective and prophylactic measures to avoid such hazardous health effects (elevated Blood carboxyhemoglobin and serum ferritin and decreased serum TIBC and UIBC that might endanger firefighters working under dangerous conditions. Firefighters must be under regular medical follow-up through standard timetabled medical laboratory investigations to allow for early detection of any serum biochemical or blood hematological changes.

Full Text Available Honey lowers prostaglandins and elevates nitric oxide (NO in various biological fluids in normal persons. NO and prostaglandin play a role in pathogenesis of AIDS. The study was designed to assess the effect of natural honey on prostaglandins and NO levels, blood indices and biochemical tests in a 40 year-old woman with AIDS. This presentation is a case story of a 40 year-old women with a long history of AIDS treated with 80g of natural honey. Plasma and urinary prostaglandin F2 alpha and thromboxane B2 levels, plasma, urine and saliva content of NO-end product (total nitrite and hematological tests were estimated before and 3 hours after oral consumption of 80g of natural honey. These variables, in addition to biochemical tests, were re-estimated after 21 days of daily consumption of 80g of natural honey. Results showed that prostaglandins level compared with normal subjects were elevated in patient with AIDS. Natural honey decreased prostaglandins levels, and elevated NO-end product, percentage of lymphocytes, platelet count, and serum protein, albumin and copper levels. It might be concluded that natural honey decreased prostaglandins level, elevated NO production and improved hematological and biochemical tests in a patient with a long history of AIDS.

2004-05-01

The effects of pregnancy on some biochemical parameters were studied using 20 sexually mature, cycling goats with weight range 20-25 kg. They were randomly separated into two groups of 10 animals each. In one group, oestrus was detected while going round with a buck in the morning and evening; a single buck on detection of oestrus mated the does and the does were tagged as pregnant after confirmation of non-return of oestrus. The other group was kept cycling and tagged as non-pregnant. The mean serum glucose concentration in pregnant does was 63.35 +/- 7.70 mg/dl, significantly lower than 71.59 +/- 1.14 mg/dl for non-pregnant does (p 0.05), as did the liver enzymes (ALT, AST). Therefore this study showed that low serum glucose and high cholesterol levels are features of mid to late pregnancy in Sahel goats.

2006-01-01

The present study was designed to investigate the effect of exposure to pulsed electromagnetic spectrum on some biochemical and hematological parameters in female albino rats. A group of mature female rats was exposed to 10 pulses of electromagnetic spectrum (frequency 8-12 GHz) 3 times/week for 3 weeks. The untreated group was considered as the control group. At the end of the experiment, serum levels of malondialdehyde, thyroid triiodothyronine and thyroxine (T3, T4), α-feto protein, estradiol, calcium, urea, creatinine and other hematological parameters were estimated. The present data revealed that serum levels of estradiol, malondialdehyde, urea, creatinine, triiodothyronine and thyroxine were elevated in the exposed group while serum calcium was significantly decreased. Non-significant difference was found in the value of α-feto protein between the two groups. The hematological studies revealed that exposure of rats to electromagnetic spectrum induced significant reduction in red blood cells (RBCs), hemoglobin concentration (Hb) and in hematocrit percent (Hct%), while reticulocyte count (Ret %) was elevated in the treated group. Non-significant changes were observed in platelets, leukocyte (WBCs) and lymphocytic counts in the exposed group as compared to the control group

Guinea pigs were exposed to sound varying from 2 to 8 kHz in frequency and 80-100 dB (SPL) in intensity for periods of 1 hr. The biochemical parameters, glucose, sodium, total protein, and the glycolytic enzymes, aldolase, phosphohexose isomerase, and total LDH as well as isozymes of the latter were ascertained for blood serum, perilymph, and, in some instances, cerebrospinal fluid. The three enzymes occurred at lower levels in perilymph as compared to blood serum. Except for a small difference in serum total protein, sound presentation incurred no significant effect on any of the above parameters. Definite differences in several metabolites were discerned for perilymph sampled according to scala and which were independent of the respective acoustical treatments. Thus, as compared to the scale tympani, the scala vestibuli perilymph displayed a higher glucose content and a diminished total LDH level and of the latter isozymes, LDH1 ranged lower and LDH2, higher. As further evidence pointing to cerebrospinal fluid as the possible origin of perilymph, similarities in glucose contents and LDH isozyme patterns were noted for both fluids. PMID:4470918

Full Text Available Crataegus species have been widely used in herbal medicine, especially for the hearth diseases. In the present study, the effect of Crataegus aronia var. dentata Browicz extract on partially hepatectomized rats was investigated with biochemical and TUNEL apoptosis assays. The extracts of the plant at the concentrations of 0.5 and 1 ml/100 g body weight/day were administered orally to the two experimental groups including partially hepatectomized rats for 42 days. At the end of the experimental period, animals were sacrificed, blood was collected for the assessment of serum levels of alanine aminotransferase (ALT, aspartate aminotransferase (AST and gamma-glutamyltransferase (GGT, and the liver tissue was used for TUNEL assay.In biochemical assay, it was found a significant decrease in the levels of serum ALT and AST in the experimental groups. On the other hand, the plant extract did not cause any significant changes in the level of GGT in these groups. In apoptosis assay, TUNEL positive hepatocytes could not be detected in both experimental groups.The present findings can suggest that Crataegus aronia var. dentata Browicz extract can decrease the levels of serum ALT and AST and play a role in apoptosis of hepatocytes in the liver of partially hepatectomized rats. However, further studies are required to confirm the effects of the plant extract on hepatoprotection and apoptosis in the regenerating liver after partial hepatectomy in animal models.

Full Text Available An estimated 40 million people in Bangladesh have been suffering from arsenic toxicity-related diseases because of drinking water contamination with high levels of naturally occurring arsenic. To evaluate the biochemical changes in chronic arsenic exposure, a total of 115 exposed subjects diagnosed as arsenicosis patients were examined and interviewed, and 120 unexposed volunteers were enrolled in this study. Drinking water, urine and peripheral blood samples were collected from all participants and analyzed. The average levels of arsenic in the drinking water and spot urine samples of the arsenicosis patients were 218.18g/L and 234.68g/L, respectively, and duration of exposure was 7.6 ± 5.2 yrs that ranged from 1-25 yrs. Prevalence of diabetes mellitus among chronic arsenic-exposed subjects was about 2.8 times higher than the unexposed subjects. The activities of alkaline phosphatase were significantly elevated in the patients, 197 U/L compared to 149 U/L in the controls, but alanine transaminase and aspartate transaminase were mostly normal. The patients had significantly lower levels of serum creatinine, 0.97 mg/dL compared to 1.15 mg/dL in the controls; but had significantly elevated levels of total protein, 84 g/L and 77 g/L respectively. The mean level of inorganic phosphate in the serum of arsenicosis patients was 6.4 mg/dL compared to 4.6 mg/dL in the unexposed subjects and the level was significantly higher, indicating substitution of the pentavalent arsenate for the phosphate ion causing underutilization of the latter. Evaluation of the lipid profiles showed while the levels of triacylglycerol were not much different, the patients had significantly lower levels of cholesterol, HDL-cholesterol and LDL-cholesterol compared to the unexposed subjects. These findings suggest significant changes in biochemical parameters in human arsenic toxicity.

Three children of two Taiwanese families were diagnosed with Laron syndrome, two sisters and one boy. Both sets of parents were consanguineous. Clinically, all three presented with the typical craniofacies of Laron syndrome, consisting of prominent forehead and hypoplastic nasal bridge, high-pitched voice, short stature, and central obesity. Biochemically, their levels of serum IGF-I were less than 5 microg/ml before and after an IGF-I generation test, and levels of IGFBP-3 were reduced in all three patients. Sequence analysis of the growth hormone receptor gene revealed that all three carried a homozygous missense D152G mutation in exon 6.

Diabetes may affect bone via bone structure, bone density, and biochemical markers of bone turnover. Lack of diagnosis and treatment of alterations of the bone tissue metabolism in type1diabetes (T1D) may lead to osteoporosis.T1D most often starts before achieving peak bone mass.Recent studies have revealed that, in T1D fracture risk is increased more than expected from the degree of decrease in bone mineral density (BMD).Osteocalcin (OC) is considered a useful biochemical marker of bone formation. As in T1D, there is absolute insulin deficiency but insulin sensitivity remains generally intact. Therefore, this study was conducted to evaluate the association between OC levels in relation the degree of residual β-cell function and other metabolic parameters in T1D In the present study, the impact of diabetes on serum OC in Egyptian children and adolescents was evaluated by comparing serum level of OC in T1D (30 subjects) and age-matched non-diabetic control (15 subjects). The present study showed that, patients with T1D had lower OC serum levels compared to the controls (7.67 ± 3.55, 21.82 ± 4.96 μg/ml respectively, p < 0.001) with a lower OC levels in diabetic females than in diabetic males (5.92 ± 3.12, 8.74 ± 2.84 μg/ml respectively, p < 0.001) and lower OC levels in pre-pubertal than pubertal diabetic patients in both genders with p < 0.05. Serum OC levels in T1D correlated with HbAIc (p < 0.001), BMI (p < 0.05), durations of T1D (p < 0.05) and total daily insulin dose (p < 0.05)and did not correlate with C-peptide levels . It may be concluded that serum OC levels in patients with T1D are regulated by a variety of developmental and metabolic pathways. Since OC levels correlated with exogenous insulin(daily insulin dose) and did not correlate with endogenous insulin (C-peptide levels), therefore, it is presumed that OC was regulated by insulin-mediated events, in presence of aggressive autoimmune destruction of pancreatic cell. These results proposed that

The long-term effect of cinacalcet hydrochloride treatment on parathyroid gland (PTG) volume has been scarcely investigated in patients with moderate to advanced secondary hyperparathyroidism (SHPT). The present study was a prospective observational study to determine the effect of cinacalcet treatment on PTG volume and serum biochemical parameters in 60 patients with renal SHPT, already treated with intravenous vitamin D receptor activator (VDRA). Measurement of biochemical parameters and PTG volumes were performed periodically, which were analyzed by stratification into tertiles across the baseline parathyroid hormone (PTH) level or PTG volume. We also determined the factors that can estimate the changes in PTG volume and the achievement of the target PTH range by multivariable analyses. Two years of cinacalcet treatment significantly decreased the serum levels of PTH, calcium, and phosphate, followed by the improvement of achieving the target ranges for these parameters recommended by the Japanese Society for Dialysis Therapy. Cinacalcet decreased the maximal and total PTG volume by about 30%, and also decreased the serum PTH level independent of the baseline serum PTH level and PTG volume. Ten out of 60 patients showed 30% increase in maximal PTG after 2 years. Multivariable analysis showed that patients with nodular PTG at baseline and patients with higher serum calcium and PTH levels at 1 year were likely to exceed the target range of PTH at two years. In conclusion, cinacalcet treatment with intravenous VDRA therapy decreased both PTG volume and serum intact PTH level, irrespective of the pretreatment PTG status and past treatment history. © 2015 The Authors.

Pigmented serum, usually due to free haemoglobin and/or bilirubin, is a common finding in dogs with babesiosis, resulting in interference with all biochemical tests that rely on photochemistry. This is particularly true of urea and creatinine determinations, complicating the diagnosis of acute renal failure, which is a serious complication of babesiosis. A disproportionately raised serum urea concentration of unknown origin occurs in severely anaemic canine babesiosis patients and gives rise to an increased serum urea:creatinine ratio. The assay for cystatin-C, an excellent measure of glomerular filtration rate, is unaffected by free serum haemoglobin, and due to its different intrinsic origins, is free of influence by the metabolic derangements and organ pathology, other than renal disease, encountered in canine babesiosis. Serum cystatin-C was used to compare the concentrations of serum urea and serum creatinine in dogs with the severely anaemic form of canine babesiosis as well as a canine babesiosis-free reference group. Mean serum urea and mean serum urea:creatinine ratio were significantly elevated in the babesia-infected group relative to the reference population in this study. Mean serum creatinine and mean serum cystatin-C were within the reference ranges. Therefore an elevated urea:creatinine ratio in canine babesiosis in the presence of a normal serum creatinine concentration is considered to be caused by an elevated serum urea concentration and is most likely of non-renal origin. Serum creatinine was therefore as specific a measure of renal function as serum cystatin-C in canine babesiosis in this study. The sensitivity of serum creatinine as a measure of renal function was not established by this study. Serum urea, however, proved to be of little use compared to serum cystatin-C and serum creatinine. Serum urea should therefore not be used to diagnose renal failure in canine babesiosis.

The glucose content in blood and the lipid content in serum and tissues of dogs exposed to chronic radiation for 3 and 5 years were studied. In tissues of these animals, the concentration of soluble DNA and DNA contained in DNP was studied in the spleen, lymph node (deep cervical node) and bone marrow of thigh bones. Results indicate that chronic gamma irradiation significantly changes concentrations of glucose in the blood, and that of several lipids in serum and tissues. A reduction in the concentration of DNP in tested organs reflects changes in the relative number of cells with various nuclear cytoplasmic ratios; most pronounced changes in biochemical indices occur in dogs exposed to chronic gamma radiation in doses of 125 rad per year.

This study was conducted to evaluate the modulating efficacy of prolonged oral administration of Foeniculum vulgare Mill. essential oil (FEO) against gamma-rays-induced biochemical changes in rats. To achieve the ultimate goal of this study, 32 rats were used, divided into 4 groups. Control group, Irradiated group with a single dose (6.5 Gy), and sacrificed after 7 days of irradiation, group 3 received FEO (250 mg/kg b.wt) for 28 successive days by gavages and group 4 received treatment of FEO for 21 days, then was exposed to gamma-rays (6.5 Gy), followed by treatment with FEO 7 days later to be 28 days. Animals were sacrificed at the end of the experiment. Transaminases (AST, ALT), alkaline phosphatase (ALP) and total bilirubin, lipids (cholesterol, triglycerides), proteins profile (total protein, albumin, globulin, and A/G ratio) as well as levels of urea, creatinine and testosterone were determined in serum. Rats exposed to gamma-rays exhibited a profound elevation of AST, ALP, bilirubin, urea and creatinine levels and lipid abnormalities. Noticeable drop in serum total protein, albumin and testosterone levels were recorded. Rats treated with FEO before and after whole body gamma-rays showed significant modulation in AST and ALT, ALP, bilirubin, urea, creatinine and lipids and noticeable improvement in the protein profile levels. It could be concluded that FEO has a beneficial protective potentials against radiation-induced some oxidative stress and biochemical perturbations

Garlic extract has various medical effects on the treatment of many diseases as hypertension, atherosclerosis, inflammation and diabetes. The alteration of the biochemical parameters in blood serum of irradiated rats may play an important role in determining the pathogenesis of radiation exposure. Many of the damaging effects of ionizing radiation are mediated by reactive free radicals. This study was designed to evaluate the protective role of garlic against gamma irradiation (5Gy) induced biochemical disorders in rats. Samples were collected at 1, 7 and 14 days post-irradiation. Lipid peroxide content (malondialdehyde), cholesterol, HDL-C, LDL-C, fatty acids, glucose, insulin, glycogen, haemoglobin, ferritin andiron were estimated.Garlic was orally administered to rats (100 mg/kg body weight) for 14 days before exposure to single dose of gamma irradiation at dose level 5 Gy. The data revealed significant increase in the levels of lipid peroxide, cholesterol, LDL-cholesterol, fatty acids, insulin, glucose and iron accompanied with significant decrease in the levels of HDL-cholesterol, glycogen, haemoglobin and ferritin due to radiation exposure. Administration of garlic alone to the rats caused nonsignificant changes in the estimated parameters indicating its safe use, but the treatment with garlic to rats before radiation exposure ameliorated the changes induced by gamma irradiation and tended to normalize their levels.It could be concluded that garlic administration may has a beneficial role in restoring the biochemical disorders induced by 5 Gy gamma irradiation

An attempt was made to assess the influence of strontium 89 on some biochemical effects, induced by external total X-irradiation of the organism in the early terms after treatment. The serum alkaline and acid phosphatase activities and the serum copper and ceruloplasmin content in rats served as indices. Inference is made that in cases, when either of the two radiation actors is alone responsible for obtaining a definite effects, their combination may integrate the biological effect, their combination may integrate the biological effects. Considerations are adduced on the dose span, within which integration of the effect may be expected. The data of this study indicate, that there is integration, when the effective dose external irradiaton effective dose internal irradiation ratio ranks from 1 : 3 to 1 : 1. No integration of effect was found in case when the effective dose of external irradiation eceeds that of internal irradiation. Data are also presented that, in conformity with the parameters studied, the minimal effective radiostrontium dose, generated in the critical organs, is approximately 3 times higher than the minimal effective dose of external irradiation.

This study is all about predicting the value of serum vaspin level in the amelioration of fatty liver and metabolic disturbance in patients with severe obesity after laparoscopic vertical banded gastroplasty (LVBG). A total of 164 patients (from January 2012 to May 2015) with severe obesity were chosen and performed LVBG. Enzyme-linked immunosorbent assay was performed to detect the serum vaspin level. The patients were given a biochemical automatic analyzer to measure the biochemical indicators. Homeostasis model assessment (HOMA) helps in the calculation of fasting insulin level (FINS) and insulin resistance (IR). The changes in fatty liver were examined by computed tomography (CT). Receiver operating characteristic curve is used to increase the predictive value of serum vaspin level in the amelioration of liver function and disturbances in the metabolism. Weight, BMI, waist circumference, serum vaspin level, and triglyceride (TG) decreased, but CT value of liver increased at 4th, 7th, and 12th month after surgery. After the 7th and 12th month period of surgery, the alanine aminotransferase, aspartate aminotransferase, FINS, and HOMA-IR reduced in the patients (P fatty liver and metabolic disturbance. This study proves that the serum vaspin level serves as a predictive indicator in the amelioration of fatty liver and metabolic disturbance in patients with severe obesity after LVBG.

Full Text Available Background: Protein energy malnutrition is the major cause of poor prognostic outcome in patients on maintenance hemodialysis (MHD. The assessment of nutritional status in patients on maintenance hemodialysis should be done both subjectively and objectively by integrating clinical, biochemical and anthropometric measurements. A study was conducted to assess the possible correlations between the subjective global assessment-dialysis malnutrition score (SGA-DMS, anthropometric measurements, and biochemical parameters in hemodialysis patients. Methods: The study included 90 patients (55 males and 35 females; age range of 25 to 73 years; mean age 52.62 ± 11.7 years undergoing twice/thrice weekly maintenance hemodialysis for six months and above in the dialysis unit of a tertiary care teaching hospital. The MHD patients were assessed by SGA -DMS, anthropometry and biochemical indicators (serum albumin, iron, ferritin and transferrin of nutritional status. Results: According to the SGA-DMS 54.4 % were moderate to severely malnourished, 31% were mild to moderately nourished and 14.4% were well nourished. There was a highly significant negative correlation between SGA –DMS and serum albumin, iron, transferrin; positive correlation between SGA-DMS and ferritin (P<0.0001. Body mass index, upper arm circumferences, and skin fold thickness had a highly significant negative correlation with SGA-DMS (P<0.001, where as the lean body mass, total body water and the fat free mass had a significant negative correlation (P<0.05. Conclusion: SGA-DMS correlated with anthropometric and biochemical parameters that are indicative of nutritional status. SGA –DMS used in conjunction with other objective nutritional assessment methods may be of greater impact in determining nutritional status of hemodialysis patients.

Background. Obesity is considered a low-grade inflammatory state and has been associated with increased acute phase proteins as well as changes in serum fatty acids. Few studies have assessed associations between acute phase proteins and serum fatty acids in morbidly obese patients. Objective. To investigate the relationship between acute phase proteins (C-Reactive Protein, Orosomucoid, and Albumin) and serum fatty acids in morbidly obese patients. Methods. Twenty-two morbidly obese patients were enrolled in this study. Biochemical and clinical data were obtained before bariatric surgery, and fatty acids measured in preoperative serum. Results. Orosomucoid was negatively correlated with lauric acid (P = 0.027) and eicosapentaenoic acid (EPA) (P = 0.037) and positively with arachidonic acid (AA) (P = 0.035), AA/EPA ratio (P = 0.005), and n-6/n-3 polyunsaturated fatty acids ratio (P = 0.035). C-Reactive Protein (CRP) was negatively correlated with lauric acid (P = 0.048), and both CRP and CRP/Albumin ratio were negatively correlated with margaric acid (P = 0.010, P = 0.008, resp.). Albumin was positively correlated with EPA (P = 0.027) and margaric acid (P = 0.008). Other correlations were not statistically significant. Conclusion. Our findings suggest that serum fatty acids are linked to acute phase proteins in morbidly obese patients. PMID:24167354

Full Text Available Aims. To analyze the influence of hyperthyroidism on the gene expression and serum concentration of leptin, resistin, and adiponectin in obese animals. Main Methods. Male Wistar rats were randomly divided into two groups: control (C—fed with commercial chow ad libitum—and obese (OB—fed with a hypercaloric diet. After group characterization, the OB rats continued receiving a hypercaloric diet and were randomized into two groups: obese animals (OB and obese with 25 μg triiodothyronine (T3/100 BW (OT. The T3 dose was administered every day for the last 2 weeks of the study. After 30 weeks the animals were euthanized. Samples of blood and adipose tissue were collected for biochemical and hormonal analyses as well as gene expression of leptin, resistin, and adiponectin. Results. T3 treatment was effective, increasing fT3 levels and decreasing fT4 and TSH serum concentration. Administration of T3 promotes weight loss, decreases all fat deposits, and diminishes serum levels of leptin, resistin, and adiponectin by reducing their gene expression. Conclusions. Our results suggest that T3 modulate serum and gene expression levels of leptin, resistin, and adiponectin in experimental model of obesity, providing new insights regarding the relationship between T3 and adipokines in obesity.

Full Text Available Background: Sulfur mustard (SM is an incapacitating chemical warfare agent, which has been widely employed in particular regions including Iran. We investigated and reported delayed biochemical and hematological complications of SM in severely toxic Iranian veterans 23 years after exposure. Materials and Methods : Forty-two Iranian veterans, residents of Khorasan Razavi, poisoned by SM, and suffering from clinical complications were investigated. A total of 30 healthy male volunteers were also selected as a control group. Biochemical and hematological variables were measured for the case and control groups. Data were analyzed using a Student′s t-test by InStat software (GraphPad Inc., San Diego, CA to determine significant differences between the data from the two groups. Results: The percentages of reticulocytes were significantly higher in patients (0.82 ± 0.04, P < 0.05. Total protein and albumin levels were significantly lower in veterans (total protein: 7.58 ± 0.07 g/dL, albumin: 4.97 ± 0.04 g/dL, P < 0.01. In addition, we observed a significant increase in serum cholesterol (226.74 ± 5.23 mg/dL, P < 0.01, triglyceride (173.53 ± 17.05 mg/dL, P < 0.05, and gamma-glutamyl transferase (GTT activity of the patients (44.04 ± 3.35 IU/L, P < 0.05. Conclusion: Results showed that SM can cause long-term effects on some biochemical factors of veterans. As many of the functional tests of liver and kidney between two groups were statistically unchanged, it seems that the observed biochemical changes may be secondary to delayed respiratory complications of the patients.

Antimitochondrial antibody (AMA) is considered the serological hallmark of primary biliary cholangitis (PBC), while data regarding the profile of AMA during ursodeoxycholic acid (UDCA) treatment are scarce. Here, we assessed the influence of UDCA treatment on titers of AMA and factors relevant to its production. Serum IgA-AMA, IgM-AMA, IgG-AMA, B cell-activating factor of the tumor necrosis factor family (BAFF), and the frequency of circulating plasmablasts were detected in PBC patients, including those who received UDCA therapy for 24 weeks, healthy controls, chronic hepatitis B patients, and autoimmune hepatitis patients. Consecutive liver sections from controls and PBC patients were stained by immunohistochemistry for detection of intrahepatic CD38 + , IgA + , IgM + , and IgG + cells. Significant decrease in titers of IgG-AMA was found only confined to PBC patients with biochemical response to UDCA treatment (P = 0.005), and similar pattern was also observed at week 24 in quantifying circulating plasmablasts (P = 0.025) and serum BAFF (P = 0.013). Notably, positive correlation between serum BAFF levels and titers of IgG-AMA, and the frequency of circulating plasmablasts were observed in PBC patients (r = 0.464, P = 0.034 and r = 0.700, P < 0.001, respectively). Additionally, in situ staining revealed significant accumulation of CD38 + and IgG + cells within the portal tracts of PBC liver. Decreased titers of serum IgG-AMA are associated with biochemical response to UDCA treatment, implicating the potentiality of this hallmark in therapeutic response evaluation and the beneficial effect of UDCA on humoral immunity in PBC patients. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

This study was conducted to evaluate the modulating efficacy of prolonged oral administration of Foeniculum vulgare Mill. essential oil (FEO) against gamma irradiation-induced biochemical changes in male rats. Essential oil of Foeniculum vulgare Mill. was orally administrated at dose level of 250 mg/kg body wt/day for 21 days before irradiation and 7 days post exposure (6.5 Gy single dose). Rats exposed to ionizing radiation exhibited a potential elevation of serum aspartate aminotransferase (AST) and alkaline phosphatase (ALP) activities, bilirubin, urea and creatinine levels, lipid abnormalities, and an increase in tissue lipid peroxidation (LPO) and metallothioneins (MTs). On the other hand, noticeable drop in liver and kidney glutathione content and serum total protein, albumin and testosterone levels were recorded. Tissue organs displayed some changes in trace element concentrations, which may be due to the radiation ability to induce oxidative stress. The data obtained from rats treated with fennel oil before and after whole body gamma irradiation revealed significant modulation in the biochemical tested parameters and profound improvement in the activity of antioxidant status, glutathione and metallothioneins. The treatment of irradiated rats with fennel oil also appeared to be effective in minimizing the radiation-induced increase in lipid peroxidation as well as changes in essential trace elements in some tissue organs. In addition to its containing many chemical antioxidant constituents such as polyphenols, fennel was found to contain detectable concentrations of essential trace elements (Zn, Cu, Fe, Se, Mg, Mn and Ca) which may be involved in multiple biological processes as constituents of enzymes system including superoxide dismutase (Cu, Zn, Mn, SODs), oxide reductase, glutathione (GSP, GSH, GST), metallothionein MTs, etc. Overall, it could be concluded that Foeniculum vulgare Mill. essential oil exerts beneficial protective role against radiation

Male albino rats were whole body subjected to 2 Gy every other day up to a total dose of 8 Gy. Animals sacrificed on the 8th day after irradiation showed significant decreases in testis/body weight ratio. Biochemical analysis in testicular tissues showed significant decreases in SOD and CAT activities, concomitant with significant increase in XO activity and TBARS contents. Radiation exposure induced also significant increases in testicular DNA fragmentation, significant increases in mitochondrial NO and Ca +2 contents associated with significant decrease in nuclear GSH content. Testicular LDL-C content showed a significant increase which was much higher than its increase in serum, the content of HDL-C increased significantly, contrarily to serum where a significant decrease was recorded. Histological examination through electron microscope revealed apoptosis in testicular tissue. Either allopurinol (50 mg/kg body weight supplied via intra peritoneal injection) or Hesperidine (200 mg/kg body weight supplied orally by gastric intubation) or allopurinol + hesperidine supplied to rats during 7 consecutive days before irradiation or during 7 consecutive days after irradiation resulted in significant decrease of apoptosis associated with significant amelioration in the disequilibrium between antioxidants and oxidants. All treatments have improved the biochemical alteration in testicular tissues as well as mitochondrial and nuclear changes. However, the improvement was significantly higher when allopurinol, or hesperidine or allopurinol + hesperidine were administered pre-irradiation than post-irradiation. According to the results obtained in the current study, it could be concluded that antioxidants supplementation would protect testicular tissues from apoptosis.

Full Text Available In this study, serum biochemistry and native protein electrophoresis in newborn calves with diarrhea and arthritis, were performed in order to evaluate the changes along with clinical findings for their possible application in the diagnosis and prognosis of disease. Based on clinical examination, animals were allotied into two groups comprising either diseased or healthy animals. Urea, creatinine, ALT, AST, LDH, albumin, total protein, glucose, total cholesterol, uric acid and iron levels were determined in the sera. Serum protein native polyacrilamide gel electrophoresis (nPAGE was performed followed by protein band ratio estimation supported with densitometry at 596 nm. Differences between the average mean of healthy and diseased animals were compared statistically (Kruskal-Walley test. In this study a decrease in serum glucose and cholesterol values (p<0.001, increase in urea, LDH levels and α1-and α2-globulin levels (p<0.01 and p<0.05 respectively were found to be associated with the disease. As a result, the observed significant changes in biochemical parameters and clinical investigation in calves, suggesting acute inflammation causing the decrease in glucose and increase in α-globulins, may be of prognostic value.

In vitro experiments are essential to understand biological mechanisms; however, the gap between monolayer tissue culture and human physiology is large, and translation of findings is often poor. Thus, there is ample opportunity for alternative experimental approaches. Here we present an approach in which human cells are isolated from human anterior cruciate ligament tissue remnants, expanded in culture, and used to form engineered ligaments. Exercise alters the biochemical milieu in the blood such that the function of many tissues, organs and bodily processes are improved. In this experiment, ligament construct culture media was supplemented with experimental human serum that has been 'conditioned' by exercise. Thus the intervention is more biologically relevant since an experimental tissue is exposed to the full endogenous biochemical milieu, including binding proteins and adjunct compounds that may be altered in tandem with the activity of an unknown agent of interest. After treatment, engineered ligaments can be analyzed for mechanical function, collagen content, morphology, and cellular biochemistry. Overall, there are four major advantages versus traditional monolayer culture and animal models, of the physiological model of ligament tissue that is presented here. First, ligament constructs are three-dimensional, allowing for mechanical properties (i.e., function) such as ultimate tensile stress, maximal tensile load, and modulus, to be quantified. Second, the enthesis, the interface between boney and sinew elements, can be examined in detail and within functional context. Third, preparing media with post-exercise serum allows for the effects of the exercise-induced biochemical milieu, which is responsible for the wide range of health benefits of exercise, to be investigated in an unbiased manner. Finally, this experimental model advances scientific research in a humane and ethical manner by replacing the use of animals, a core mandate of the National

Polyphenols of natural and synthetic origin are exploited in tanning sector to convert putrescible skin/hide to non-putrescible leather. However, only 30-40% of the inputs have been taken up for processing, the remaining is released as unspent. The existing conventional wastewater treatment systems are inefficient in removing or degrading these unspent polyphenols and thus detrimental to ecosystem. The present study demonstrates the evaluation of impact of both synthetic and natural polyphenols on biochemical and haematological properties of blood and serum in animal models. The results reveal that concentrations of polyphenols play a major role. At higher concentrations, irrespective of their nature, there was a marked change in the lipid profile (81% reduction), followed by insignificant change in glucose levels, RBC and WBC counts and other haematological parameters. At lower concentrations, no significant changes in the above said properties were observed.

Serum Brain-Derived Neurotrophic Factor (BDNF) levels are associated with neurotransmission and cognitive functions. The goal of this study was to examine the effect of general anesthesia on BDNF levels. It was also to reveal whether this effect had a relationship with the surgical stress response or not. The study included 50 male patients, age 20-40, who were scheduled to have inguinoscrotal surgery, and who were in the ASA I-II risk group. The patients were divided into two groups according to the anesthesia techniques used: general (GA) and spinal (SA). In order to measure serum BDNF, cortisol, insulin and glucose levels, blood samples were taken at four different times: before and after anesthesia, end of the surgery, and before transferal from the recovery room. Serum BDNF levels were significantly low (p BDNF and the stress hormones. Our findings suggested that general anesthetics had an effect on serum BDNF levels independent of the stress response. In future, BDNF could be used as biochemical parameters of anesthesia levels, but studies with a greater scope should be carried out to present the relationship between anesthesia and neurotrophins.

We analyzed biochemical data derived from 911 patients with renal insufficiency observed at our institution for periods up to 7 years. During early renal failure (RF) (creatinine less than 5 mg/dL), the rate of change of hematocrit, total CO2 (tCO2) and urea per unit change of creatinine was significantly higher than during moderate (creatinine between 5 and 10 mg/dL) or advanced (creatinine greater than 10 mg/dL) RF. For example, the rate of change of hematocrit (%, volume/volume [v/v]) was (mean +/- SEM) -2.15 +/- 0.15% for each 1 mg/dL increase in creatinine in the range of creatinine less than 5 mg/dL, whereas for the range of creatinine greater than 10 mg/dL, the rate of change was only -0.48 +/- 0.06% (P less than 0.001). Similarly, the rate of change of tCO2 was -1.68 +/- 0.09 mEq/L for each 1 mg/dL increment in creatinine concentration during early RF, and -0.19 +/- 0.09 mEq/L per unit increase in creatinine during advanced RF (P less than 0.001). Chloride concentration initially increased as a function of creatinine in early RF, but decreased in advanced RF, whereas the anion gap increased throughout the course of RF. Mean serum phosphate concentration also increased steadily, but remained below the upper range of normal (4.7 mg/dL) during early RF without the use of phosphate binders. These data suggest that different biochemical parameters change at different rates as a function of the severity of renal dysfunction, and that although phosphate retention may occur, hyperphosphatemia is not a hallmark of early RF.

OBJECTIVE Progranulin has recently been introduced as a novel adipokine inducing insulin resistance and obesity. In the current study, we investigated renal elimination, as well as association of the adipokine with markers of the metabolic syndrome. RESEARCH DESIGN AND METHODS Progranulin serum levels were quantified by enzyme-linked immunosorbent assay and correlated to anthropometric and biochemical parameters of renal function and glucose and lipid metabolism, as well as inflammation, in 532 patients with stages 1–5 of chronic kidney disease (CKD). RESULTS Median serum progranulin levels adjusted for age, sex, and BMI were significantly different between CKD stages with highest values detectable in stage 5 (stage 1, 58.3 µg/L; stage 2, 63.0 µg/L; stage 3, 65.4 µg/L; stage 4, 68.8 µg/L; and stage 5, 90.6 µg/L). Furthermore, CKD stage was the strongest independent predictor of circulating progranulin in our cohort. In addition, high-sensitivity interleukin-6 and adiponectin remained significantly and independently correlated with the adipokine. CONCLUSIONS We demonstrate that progranulin serum levels increase with deteriorating renal function. These findings are in accordance with the hypothesis that renal clearance is a major elimination route for circulating progranulin. Furthermore, the adipokine is positively and independently associated with markers of inflammation and adiponectin. PMID:23033238

The Present study was designed to study the effect of exposure to electromagnetic field (EMF), emitted from a cellular tower for mobile phone on some biochemical and haematological parameters in male albino rats and to evaluate of the possible protective role of the antioxidant glutathione enhancer on the studied parameters. Three groups of rats were studied, the control (unexposed), the exposed and the treated exposed groups. Exposed groups were subjected to EMF at frequency of 900 MHz, with a peak power of about 60 W, power density of 0.05 mW/ cm"2 at the site of exposure for 24 h/ day for 8 weeks, at the same time treated group was supplied with oral injection of glutathione enhancer three times weekly. At the end of experiment, serum levels of thyroid stimulating hormone (TSH), calcium (Ca), uric acid, malondialdehyde (MDA) beside, the activity of lactate dehydrogenase (LDH) were measured also, some haematological parameters were estimated. Impairment of TSH and serum calcium was expressed by a decrease in serum levels of the exposed group. Meanwhile, serum level of MDA, uric acid and the activity of LDH were increased by exposure. The haematological studies revealed that, exposure to electromagnetic spectrum induced significant reduction in red blood cell counts (RBC's), and haemoglobin concentration (Hb), meanwhile reticulocyte count (Ret) was elevated. The leucocyte counts (WBC's) and platelets count were not affected by exposure. The study demonstrated that glutathione enhancer can attenuate the side effects of exposure to electromagnetic field.

The giant panda ( Ailuropoda melanoleuca) is a high-profile threatened species with individuals in captivity worldwide. As a result of advances in captive animal management and veterinary medicine, the ex situ giant panda population is aging, and improved understanding of age-related changes is necessary. Urine and blood samples were collected in April and July 2015 and analyzed for complete blood count, serum biochemistry, and biochemical and microscopic urine analysis for all individuals sampled ( n = 7, 7-16 yr of age) from giant panda housed at the China Research and Conservation Centre for the Giant Panda in Bifengxia, Sichuan Province, China. Hematology and serum biochemistry values were similar to those previously reported for giant panda aged 2-20 yr and to Species360 (formerly International Species Information System) values. Urine was overall dilute (urine specific gravity range: 1.001-1.021), acellular, and acidic (pH range: 6-7). This is the first report of hematologic and serum biochemistry, with associated urinalysis values, in the giant panda aged 7-16 yr.

Objective: To investigate the correlation between serum Omentin-1 levels and the presence of osteoporosis in older men. Methods: Serum Omentin-1, bone turnover biochemical markers, and bone mineral density (BMD) were determined in 45 older men with osteoporosis or 45 older men without osteoporosis (65e70 years old). Results: Omentin-1 levels were increased in older men with osteoporosis, and the differences remained significant after con-trolling for fat mass. Omentin-1 was negatively correlated with BMD. In a multiple linear stepwise regression analysis, Omentin-1, lean mass, but not fat mass, were independent predictors of BMD for the combined group. Significant negative correlations between Omentin-1 and bone-specific alkaline phosphatase (BAP) and bone cross-linked N-telopeptides of typeⅠcollagen (NTX) were found. Omentin-1 was also independently associated with BMD and bone turnover markers in older men with osteoporosis and control groups that were considered separately. Conclusions: Omentin-1 is an independent predictor of BMD in older men with osteoporosis, and it is negatively correlated with bone turnover biochemical markers. It is suggested that Omentin-1 may exert a negative effect on bone mass through the regulation of the osteoblast differentiation in the older men with osteoporosis.

Fascioliasis is caused by Fasciola hepatica and F. gigantica. The latter, always considered secondary in human infection, nowadays appears increasingly involved in Africa and Asia. Unfortunately, little is known about its pathogenicity, mainly due to difficulties in assessing the moment a patient first becomes infected and the differential diagnosis with F. hepatica. A long-term, 24-week, experimental study comparing F. hepatica and F. gigantica was made for the first time in the same animal model host, Guirra sheep. Serum biochemical parameters of liver damage, serum electrolytes, protein metabolism, plasma proteins, carbohydrate metabolism, hepatic lipid metabolism and inflammation were analysed on a biweekly basis as morbidity indicators. Serum anti-Fasciola IgG, coproantigen and egg shedding were simultaneously followed up. rDNA and mtDNA sequencing and the morphometric study by computer image analysis system (CIAS) showed that fasciolids used fitted standard species characteristics. Results demonstrated that F. gigantica is more pathogenic, given its bigger size and biomass but not due to genetic differences which are few. Fasciola gigantica shows a delayed development of 1-2 weeks regarding both the biliary phase and the beginning of egg shedding, with respective consequences for biochemical modifications in the acute and chronic periods. The higher F. gigantica pathogenicity contrasts with previous studies which only reflected the faster development of F. hepatica observed in short-term experiments. © The Author 2015.

We aimed to define whether vitamin E improves biochemical indices associated with symptoms of atopic dermatitis-like inflammation in NC/Nga mice. After picryl chloride (PC) application to their backs, changes in the content of thiobarbituric acid reactive substances (TBARS) and vitamin E, as well as the activity of antioxidant enzymes (superoxide dismutase (SOD), glutathione peroxidase (GSHPx) and catalase) were analyzed in the serum and skin of NC/Nga mice during a symptomatic cycle. The levels of inflammatory factors were also assessed, including IgE, cyclooxigenase-2 (COX-2), tumor necrosis factor (TNF-α) and nuclear factor-κB (NF-κB). When allergic dermatitis was induced by the application of PC to the skin of the mice, skin inflammation appeared 2 wk after PC application, with the peak severity of inflammation observed 5 wk after PC application. Subsequently, the animals recovered from the inflammation by 9 wk after PC application. The TBARS content in the skin and serum increased markedly when the symptoms were the most severe, and decreased to levels near those in control mice by 9 wk after PC application. The activities of SOD and GSHPx in the skin and serum were also positively correlated with symptomatic changes; however, no change in catalase activity was observed 5 wk after PC application. Conversely, vitamin E content decreased at the stage of peak severity. The levels of all inflammatory factors analyzed in this study were altered in a manner similar to other indices. Additionally, vitamin E treatment markedly inhibited these PC-induced alterations. On the basis of these results, it is expected that the observed alterations in biochemical indices, which reflect the symptomatic cycle, may be applicable to objective diagnosis and treatment for atopic dermatitis, and that vitamin E may improve the symptoms of AD.

A radioimmunoassay (RIA) for measurement of serum haloperidol is described. Compared to gaschromatography (GC), RIA vaues average 40% higher. However, a simple organic extraction of serum yields statistically equivalent RIA and GC haloperidol determinations. For both men and women combined, there was a positive correlation between dose (mg/kg/day) and steady-state serum haloperidol level (r = +0.86) and between steady-state serum haloperidol and serum prolactin (PRL) concentration

In traditional Chinese medicine, Glechoma hederacea is frequently prescribed to patients with cholelithiasis, dropsy, abscess, diabetes, inflammation, and jaundice. Polyphenolic compounds are main bioactive components of Glechoma hederacea. This study was aimed to investigate the hepatoprotective potential of hot water extract of Glechoma hederacea against cholestatic liver injury in rats. Cholestatic liver injury was produced by ligating common bile ducts in Sprague-Dawley rats. Saline and hot water extract of Glechoma hederacea were orally administrated using gastric gavages. Liver tissues and bloods were collected and subjected to evaluation using histological, molecular, and biochemical approaches. Using a rat model of cholestasis caused by bile duct ligation (BDL), daily oral administration of Glechoma hederacea hot water extracts showed protective effects against cholestatic liver injury, as evidenced by the improvement of serum biochemicals, ductular reaction, oxidative stress, inflammation, and fibrosis. Glechoma hederacea extracts alleviated BDL-induced transforming growth factor beta-1 (TGF-β1), connective tissue growth factor, and collagen expression, and the anti-fibrotic effects were accompanied by reductions in α-smooth muscle actin-positive matrix-producing cells and Smad2/3 activity. Glechoma hederacea extracts attenuated BDL-induced inflammatory cell infiltration/accumulation, NF-κB and AP-1 activation, and inflammatory cytokine production. Further studies demonstrated an inhibitory effect of Glechoma hederacea extracts on the axis of high mobility group box-1 (HMGB1)/toll-like receptor-4 (TLR4) intracellular signaling pathways. The hepatoprotective, anti-oxidative, anti-inflammatory, and anti-fibrotic effects of Glechoma hederacea extracts seem to be multifactorial. The beneficial effects of daily Glechoma hederacea extracts supplementation were associated with anti-oxidative, anti-inflammatory, and anti-fibrotic potential, as well as down

An investigation was conducted to study the biochemical and neurochemical effects of moniliformin mycotoxins in rats. Moniliformin was extracted from fusarium oxysporum and injected intraperitoneally to male albino rats at a dose level 225 magaa g/kg (1/220 LD 5 0) daily for three weeks. The results. The results revealed a decrease in body weight of treated animals, in addition to alteration in the weights of some selected organs. A significant increase of serum ALT, AST and ALP were observed, indicating changes in liver function. Kidney function of treated rats as determined by alteration creatinine and blood urea also was affected. On the other hand the data obtained revealed a dramatic decrease in brain acetylcholinesterase activity. In addition, moniliformin exhibited alteration in the total content of catecholamines, dopamine (DA), norepinephrine (NE), serotonine (5-HT), 5-hydroxyindoleacetic acid (5-HIAA), free inorganic phosphate (Pi) and gamma-aminobutyric acid (GABA) in rat brain of treated animals. Also, profound decline in serum testosterone level was observed. No pathological changes were detected. Hormonal assays were performed using radioimmunoassay techniques

The present study reports the haematological and biochemical protective effect of Salipriina on Swiss albino mice exposed to gamma radiation. Swiss albino mice (8 weeks old) were administered intraperitoneally Sanepil (800 mg/kg b.wt.) prior to whole body gamma-irradiation (7.5 Gy). Radiation exposure resulted in a significant decline in different bone marrow cells (pro-and normoblasts) and blood constituents (erythrocytes, leukocytes, differential leukocyte count, haematocrit,haemoglobin and erythrocyte sedimentation rate). Pro- and normoblasts, erythrocytes, leukocytes, haematocrit and haemoglobin values showed a significant (p<0.05) decline during the first 3 days, followed by a gradual recovery starting from day 7, but normal values were not recorded until 14 days post-exposure. Treatment of mice with Spirulina also caused a significant decrease in malondialdehyde (MDA) formation in the liver, suggesting its role in protection against radiation induced membrane and cellular damage. Similarly, pretreatment of mice with Spirulina caused a significant increase in serum glutathione (GSH) level in comparison with that of irradiated animals. Results suggest that Spirulina modulate the radiation induced hematological and biochemical alterations in Swiss albino mice

The roles of deficient or deranged insulin, adiponectin and 25 hydroxy vitamin D (25[OH]D) levels regulating food intake, energy metabolism, glucose and lipid metabolism and body weight have been reported in the pathogenesis of prediabetes and type 2 diabetes mellitus. However, their congruity in the etiology of diabetes mellitus is unknown. Thus, the aim of the study was to investigate the roles of these parameters together and to establish their interrelationship in patients with prediabetes and diabetes. The preliminary cross-sectional study included 77 persons with type 2 diabetes who were matched for age, sex and body mass index (BMI); 73 persons with prediabetes; and 52 healthy control subjects. Fasting serum levels of adiponectin, insulin and 25(OH)D were measured by commercially available immune assay kits, and routine biochemical parameters were analyzed in all study groups. The results show statistically significant lower levels of serum adiponectin and serum 25(OH)D and higher serum insulin levels in persons with prediabetes or type 2 diabetes with respect to controls. The changes in the serum adiponectin or serum 25(OH)D in persons with prediabetes and type 2 diabetes were found to be inversely correlated with the serum levels of insulin. Moreover, multiple linear regression analysis, with 25(OH)D, insulin and homeostatic model assessment-insulin resistance (HOMA-IR) as the variables, revealed that serum adiponectin levels might be an independent risk factor for the progression of prediabetes and type 2 diabetes in subjects. The association of these hormones might act as a significant predictor of progression of prediabetes to type 2 diabetes. Decreased serum adiponectin levels might be an independent risk factor for progression to prediabetes and type 2 diabetes, which may help in developing experimental models of the disease or in identifying biomarkers or disease-modifying drugs.

Muscle sufficiency was significantly lower in 1336 children with chronic malnutrition of moderate to severe degree. 18 children with a chronic moderate degree of malnutrition and 8 well-nourished age-matched controls were selected for biochemical and 31-phosphorus magnetic resonance spectroscopy (31-P MRS) studies. The results shows that: a) serum total protein, albumin, iron, calcium and inorganic phosphate were similar in both groups; b) serum enzyme levels were significantly increased in the malnuourished group; c) 31-P MRS showed significantly higher means for total ATP, β-ATP, α-ATP and inorganic phosphate for the malnourished compared to the control group. In chronic malnutrition, proteins are maintained by degradation in muscle resulting in release of amino acids and enzymes. 31-P MRS studies showing increases in total ATP, β-ATP and inorganic phosphate and a decrease in phosphocreatine suggest that ATP is maintained at the cost of phosphocreatine. 22 refs., 4 tabs. 1 fig

Full Text Available From a complex experiment of establishing the effects of lecithin supplemented in the diet of small ruminants, in this paper we present the influence of lecithin on some sanguine biochemical parameters at lactating sheep and goat. The researches were made on a experimental group formed by 5 sheep from łurcana breed and 5 goats from Crapatina breed, which were fed in the first experimental period with a base ratio (Br formed by 1.5 kg of hill hay and 0.2 kg concentrate forage mixture, in the second experimental period the Br was supplemented with 100 g lecithin/day/animal. At the end of each experimental period were taken blood samples to establish some biochemical parameters from sanguine serum. The supplementation of base ration with 100 g lecithin/day/animal at lactating sheep and goats did not produced significant changes to values of total proteins (TS, albumin, creatinine, urea and total bilirubins (TB from sanguine serum. Contrary to expectation the cholesterol and triglycerides were higher than normal both in sheep (from 82 mg/dl to 83 mg/dl for cholesterol and from 23 mg/dl to 45 mg/dl for triglycerides but specially in goats (from 59 mg/dl to 68 mg/dl for cholesterol and from 24 mg/dl to 55 mg/dl for triglycerides. Were registered significant increment of activity of alkaline phosphatase and in γ – GT and a decrease of plasmatic activity of pancreatic α-amylase both in sheep and goats.

The present investigation was carried out to evaluate the effect of ginger extract (100 mg/kg b.wt) for five weeks on some biochemical changes induced in rats administered daily oral dose of organophosphorus pesticide diazinon at the level of 40 mg/kg b.wt for five weeks and/or high fat (butter oil) at the dose level 16 ml/kg b.wt for five weeks.The data showed that the pesticide and high fat caused disturbance in liver function and significant decrease in deoxyribonucleic acid (DNA), ribonucleic acid (RNA) and levels of total protein. Moreover, these changes were associated with disturbances in the carbohydrate metabolism in liver through the significant increase in liver glycogen, lactate and bilirubin levels, with significant decrease in serum glucose levels. Also, disturbance in liver lipid metabolism was occurred through significant increase in serum triglycerides, total cholesterol, LDL-cholesterol and significant decrease in HDL-cholesterol. Moreover, a significant decrease in serum testosterone level was also observed.The results showed that extended administration of ginger extract during diazinon pesticide and/or high fat treatment minimized the disturbance and injury induced in liver function and testis.

Full Text Available Hyperemesis gravidarum is a severe manifestation of nausea and vomiting of pregnancy and it is associated with weight loss and metabolic abnormalities. It is known that abnormal laboratory values, including mildly elevated serum lipase level, could be associated with hyperemesis gravidarum. However, in this case report details of two women with hyperemesis gravidarum but with significantly elevated serum lipase levels were discussed. These patients presented with severe nausea and vomiting but without abdominal pain. They were found to have severely elevated lipase levels over 1,000 units/liter. In the absence of other findings of pancreatitis, they were treated with conservative measures for hyperemesis gravidarum, with eventual resolution to normal lipase levels. Although significantly elevated lipase level in pregnant patients with nausea and vomiting is a concern for acute pancreatitis, these two cases of significantly elevated serum lipase without other clinical findings of pancreatitis led to this report that serum lipase could be quite elevated in hyperemesis gravidarum and that it might not be an accurate biochemical marker for acute pancreatitis. Imaging studies are thus necessary to establish the diagnosis of acute pancreatitis.

Psoriasis has been considered as systemic disorder. Lipocalin-2 might be a link between psoriasis and its comorbidities. Aim of the study was to investigate the associations between serum lipocalin-2 levels and the disease activity, markers of inflammation or metabolic disturbances and changes after topical treatment in psoriatic patients. Thirty-seven individuals with active plaque-type psoriasis and 15 healthy controls were recruited. Blood samples were collected before and after 14 days of therapy. Serum lipocalin-2 concentrations were examined by enzyme-linked immunosorbent assay. The results were correlated with Psoriasis Area and Severity Index (PASI), body mass index (BMI), inflammatory and biochemical markers, lipid profile and with effectiveness of topical treatment. Lipocalin-2 serum levels were significantly increased in psoriatic patients in comparison to the controls (p = 0.023). No significant correlations with indicators of inflammation, nor BMI or PASI were noted. A statistical association between lipocalin-2 and low-density lipoprotein-cholesterol was shown. After topical treatment serum lipocalin-2 level did not significantly change (p = 0.9), still remaining higher than in the controls, despite clinical improvement. Lipocalin-2 might be a marker of psoriasis and convey cardiovascular or metabolic risk in psoriatic patients, but may not be a reliable indicator of inflammation, severity of psoriasis nor efficacy of antipsoriatic treatment.

Full Text Available Hyperhomocysteinemia (HHC, both basal and after methionine load, may occur due to genetic disorders or deficiencies of nutrients that affect the remethylation or trans-sulphuration pathways during methionine metabolism. HHC is involved in the pathogenesis of many illnesses as a result of its prooxidative effect and its impairment of antioxidative protection. The aim was to examine the effects of subchronic methionine overload on the body weight and standard biochemical parameters in rat serum and to examine whether simultaneous subchronic intraperotoneal administration of methionine alone or together with L-cysteine or N-acetyl-cysteine resulted in a change in the body weight and biochemical parameters in the rat serum. The research was conducted during a three-week period (male Wistar albino rats, n=36, body weight of approximately 160 g, age of 15-20 days, and the animals were divided into a control group and three experimental groups of 8-10 animals each: a control group (0.9% sodium chloride 0.1-0.2 ml/day; b methionine (0.8 mmol/kg/bw/day (MET group; c methionine (0.8 mmol/kg/bw/day + L-cysteine (7 mg/kg/bw/day (L-cys+MET group; and d methionine (0.8 mmol/kg/bw/day + N-acetyl-L-cysteine (50 mg/kg/bw/day (NAC+MET group. In addition to the body weight monitoring, the levels of total homocysteine and the standard biochemical parameters in blood samples (plasma or serum were determined. The results indicated that monitoring the homocysteine levels and standard biochemical parameters in blood could be used for analysis and could provide an excellent guideline for distinguishing between toxic and non-toxic doses of methionine intake, which may be meaningful for clinical applications.

Full Text Available Aim: An experimental study was conducted on 192-day-old broiler chicks for evaluating the effect of 10% neem leaf extract (NLE supplementationon biochemical parameters in chickens experimentally infected with Escherichia coli O78 at 107 CFU/0.5 ml at 7 days of age. Materials and Methods: The 192-day-old broiler chicks were procured. These chicks were divided into two groups (A and B containing 96 birds each on the 1st day. Diet of all the chicks of Group A was supplemented with 10%NLE in water, whereas chicks of Group B were given feed and water devoid of NLE supplementation throughout the experiment. After rearing for 1 week, chicks of both the groups (A and B were again divided into two subgroups (Group A into A1 and A2 and Group B into B1 and B2 of 54 and 42 birds, respectively. At the age of 7 days all the chicks of groups A1 and B1 were injected with E. coli O78 at 107 CFU/0.5 ml intraperitoneally. Blood samples were collected from six chicks from each group at day 0, 2, 4, 7, 14, 21, 28 days post-infection and serum was separated for biochemical studies. Results: There was a significant increase in serum alanine transaminase (ALT, aspartate transaminase (AST, lactate dehydrogenase (LDH activities, globulin concentration and a decrease in total protein (TP, albumin concentrations, and alkaline phosphatase (ALP activity in both the infected groups. However, the changes in biochemical values, i.e., ALT, AST, LDH, ALP, TP, albumin, and globulin wereof lower magnitude in NLE supplemented group suggesting hepatoprotective and cardioprotective effect of NLE. Conclusions: Fromthe present study, it is reasonable to conclude that significant increase in the value of ALT, AST, LDH, globulin, and significant decrease in the value of ALP, TP, and albumin was of lower magnitude in supplemented infected group (A1 as compared to non-supplemented infected group (B1 suggesting hepatoprotective and cardioprotective effect of NLE.

Full Text Available Convolvulus L., the second largest genus of the family Convolvulaceae, has about 250 species distributed mainly in the temperate and tropical regions of the world, with a cosmopolitan distribution. According to recent studies, this genus is represented in Turkey by 33 species, 9 of which are endemic. Convolvulus species are extensively used in traditional medicine for various purposes as in ulcer treatment, diabetes, and tension. The aim of this study was to investigate the antioxidant activity and the effects of Convolvulus aucheri extract on biochemical indices in rats.The antioxidant activities of various solvent extracts (methanol, ethanol, acetone and benzene obtained from C. aucheri were evaluated by using 2,2-diphenyl-1-picrylhydrazyl (DPPH and β-carotene-linoleic acid assays. In addition, total phenolic contents in all the extracts of C. aucheri were determined as gallic acid equivalents. As for the biochemical assay, the extracts of the plant at the concentrations of 0.5 and 1 ml/100 g body weight/day were administered orally to the experimental groups for 36 days. Blood samples were taken by cardiac venipuncture on the 2nd and 4th weeks after the initial treatment. Aspartate aminotransferase (AST, alanine aminotransferase (ALT, gamma-glutamyltransferase (GGT and blood urea nitrogen (BUN were measured for the determination of liver function.Among all the extracts, the ethanolic extracts of C. aucheri showed the highest antioxidant activity (66.88 ± 0.8%. The highest free radical scavenging activity (59.50 ± 1.2% was recorded on the ethanolic extracts. The phenolic contents of the ethanolic extracts are higher than the other types of extracts (23.03 mg/g GAE. In biochemical assay, it was found a significant increase in the levels of serum ALT, AST and decrease the serum GGT levels in the experimental groups when compared to the controls (p<0.05. On the other hand, we found significant increase in the level of BUN.

Phenobarbital is a commonly employed antidepressant and anti-epileptic drug. The cancer promoting activity of this genotoxic xenobiotic is often ignored. It is responsible for oxidative stress leading to modulation in xenobiotic and antioxidative enzymes. Glucosinolates and more specifically their hydrolytic products are known for their antioxidative and anticancer activities. The present study involves the analysis of hepatoprotective effect of erucin (isolated from Eruca sativa (Mill.) Thell.) against phenobarbital mediated hepatic damage in male wistar rats. The liver homogenate was analyzed for oxidative stress (superoxide dismutase, catalase, guaiacol peroxidase, ascorbate peroxidase, glutathione reductase and lactate dehydrogenase), other oxidative parameters (thiobarbituric acid reactive species, conjugated dienes and lipid hydroperoxide), phase I enzymes (NADPH-cytochrome P450 reductase, NADH-cytochrome b5 reductase, cytochrome P420, cytochrome P450 and cytochrome b5), phase II enzymes (γ-glutamyl transpeptidase, DT-diaphorase and glutathione-S-transferase), serum parameters (alkaline phosphatase, serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase, direct bilirubin and total bilirubin) and certain histological parameters. Erucin accorded protection from phenobarbital induced hepatic damage by normalizing antioxidative enzymes, other oxidative parameters, phase I, II, and serum parameters. Erucin, an analogue of sulforaphane has the potential to act as an anticancer agent by regulating various biochemical parameters.

Full Text Available Objectives: The present study investigated the protective effect of Wattakaka (W. volubilis leaf extract against streptozotocin (STZ-induced diabetes in rats. Methods: Male Wistar rats were divided into five groups (with six rats in each group and were fed ad libitum. The rats were fasted for sixteen hours before diabetes was induced by injecting a single dose of 90 mg/kg body weight of STZ in 0.9-percent normal saline through an intraperitoneal route. The five groups were as follows: Group 1: normal control (saline-treated, Group 2: untreated diabetic rats, Groups 3 and 4: diabetic rats treated orally with petroleum ether cold maceration extract (PEME of W. volubilis (50 and 100 mg/kg body weight, and Group 5: diabetic rats treated orally with metformin (250 mg/kg body weight. All rats received treatment for 21 days. For the STZ-induced diabetic rats, the blood-glucose, α-amylase, total protein and alanine transaminase (ALT levels were measured on days 7,14 and 21 of the treatment with PEME of W. volubilis and the treatment with metformin. Histopathological changes in the liver were examined with hematoxylin-eosin staining. Morphological changes in the liver were also examined with glutaraldehyde fixation. Results: The treatments with PEME of W. volubilis and with metformin in experimental rats by oral injections for 21 days produced reductions in the levels of serum biochemical markers. Histopathology and scanning electron microscopy results showed that the administrations of PEME of W. volubilis and of metformin suppressed the generation of abnormal liver cells in the STZ-treated rats. Conclusion: These results suggest that both PEME of W. volubilis and metformin have a protective effect against STZ-induced diabetes.

To establish reference intervals for serum and cerebrospinal fluid (CSF) parameters in clinically healthy adult miniature donkeys. Experiments were conducted on 10 female and 10 male clinically normal adult miniature donkeys, randomly selected from five herds. Lumbosacral CSF collection was performed with the sedated donkey in the standing position. Cell analysis was performed immediately after the samples were collected. Blood samples were obtained from the jugular vein immediately after CSF sample collection. Sodium, potassium, glucose, urea nitrogen, total protein, calcium, chloride, phosphorous and magnesium concentrations were measured in CSF and serum samples. A paired t-test was used to compare mean values between female and male donkeys. The CSF was uniformly clear, colourless and free from flocculent material, with a specific gravity of 1.002. The range of total nucleated cell counts was 2-4 cells/μL. The differential white cell count comprised only small lymphocytes. No erythrocytes or polymorphonuclear cells were observed on cytological examination. Reference values were obtained for biochemical analysis of serum and CSF. Gender had no effect on any variables measured in serum or CSF (p>0.05). CSF analysis can provide important information in addition to that gained by clinical examination. CSF analysis has not previously been performed in miniature donkeys; this is the first report on the subject. In the present study, reference intervals for total nucleated cell count, total protein, glucose, urea nitrogen, sodium, potassium, chloride, calcium, phosphorous and magnesium concentrations of serum and CSF were determined for male and female miniature donkeys.

Hereditary primary hyperparathyroidism may be syndromic or nonsyndromic (familial isolated hyperparathyroidism). Recently, germline activating mutations in the GCM2 gene were identified in a subset of familial isolated hyperparathyroidism. This study examined the clinical and biochemical characteristics and the treatment outcomes of GCM2 mutation-positive familial isolated hyperparathyroidism as compared to sporadic primary hyperparathyroidism. We performed a retrospective analysis of clinical features, parathyroid pathology, and operative outcomes in 18 patients with GCM2 germline mutations and 457 patients with sporadic primary hyperparathyroidism. Age at diagnosis, sex distribution, race/ethnicity, and preoperative serum calcium concentrations were similar between the 2 groups. The preoperative serum levels of intact parathyroid hormone was greater in patients with GCM2-associated primary hyperparathyroidism (239 ± 394 vs 136 ± 113, P = .005) as were rates of multigland disease and parathyroid carcinoma in the GCM2 group (78% vs 14.3%, P hyperparathyroidism patients have greater preoperative parathyroid hormone levels, a greater rate of multigland disease, a lesser rate of biochemical cure, and a substantial risk of parathyroid carcinoma. Knowledge of these clinical characteristics could optimize the surgical management of GCM2-associated familial isolated hyperparathyroidism. Published by Elsevier Inc.

This study was conducted using a total of 360 22-day-old Chaohu ducks to evaluate the effect of rearing system on growth performance, carcass traits, meat quality and serum parameters of male and female Chaohu ducks. The birds were divided and raised in separate pens according to sex and rearing system, with three replicate pens of 30 male or 30 female ducks per pen for each rearing system. The rearing systems consisted of a floor rearing system (FRS) and a net rearing system (NRS). Results showed that ducks raised in NRS had better growth performance, whereas, ducks raised in FRS exhibited better carcass traits and meat color, and lower intramuscular fat. For the serum parameters, NRS significantly decreased high-density lipoprotein cholesterol content, and enhanced total protein and triacylglycerol contents. Male ducks had lower abdominal fat percentage, and higher growth performance and shear force, but there were no other significant differences between sexes. No rearing system × sex interaction was observed in the present study, revealing that rearing system had the same effect on both sexes. In conclusion, NRS was beneficial to the growth performance of Chaohu ducks, whereas this system had some negative effects on carcass traits, meat quality and serum profiles. © 2018 Japanese Society of Animal Science.

This study assessed the applicability of serum and urine cotinine as a biochemical marker of self-reported smoking habits for use in a preconception smoking cessation program. The variation of serum and urine cotinine over the course of the day was investigated in a sample of 21 smokers and 8 passive smokers who reported their smoking habits and exposure to smoke daily in a questionnaire for 10 consecutive days. Blood and urine samples were collected on two sampling days, 1 week apart. Both serum and urine cotinine assay could distinguish between passive and active smokers, but not between higher categories of smokers (1019 and ≥20 cigarettes per ay) due to significant intersubject overlap. In serum, no significant differences were found between morning and afternoon cotinine concentrations in either day, in contrast to urine cotinine (with lower excretions observed n the morning). An overall coefficient of variation of 22- was observed for both specimens in smokers. Because serum cotinine is subject to lower variability over the course of the day, it is more practical for use in a clinical setting where appointments are scheduled throughout the day in order o confirm smoking status

To investigate the mechanism and relationship between hyperthyroidism and osteoporosis, bone mineral density was observed using dual-energy X-ray absorptiometry in 149 cases of hyperthyroidism, while serum FT 3 , FT 4 , TSH, alkaline phosphatase (ALP), BGP, and D-pyd levels were measured in 81 cases of hyperthyroidism. The osteopenia rate is 30.2% and the osteoporosis rate is 24.1% in hyperthyroidism patients. Compare with control group, bone metabolic biochemical markers in all cases of hyperthyroidism showed a significant increase, which displays high turnover osteoporosis. In order to find out the case of osteoporosis as soon as possible, bone mineral density of all patients with hyperthyroidism should be measured in the period of treatment. (authors)

2003-01-01

The present work deals with the effect of feeding 150 mg dicophane/ kg, an organochlorine pesticide, and / or 6 Gy whole body gamma irradiation on albino rats which produced several alternations in blood biochemical components. Alkaline phosphatase (AP), cholinesterase (ChE), creatinine and urea were increased significantly for dicophane and or gamma irradiation treatment, while protein level was increased after dicophane treatment and decreased by radiation. On the other hand, serum levels of bilirubin tended to decrease allover the experimental periods. Dicophane feeding caused decrease in cholesterol and glucose levels till 7 and 15 days, respectively, then increased significantly after 30 days, and also significant increase were observed in their levels after dicophane and/ or gamma irradiation treatments

Full Text Available Introduction. Although 90% of prostate cancer is considered to be localized, 20%–30% of patients will experience biochemical failure (BF, defined as serum PSA >0.2 ng/mL, after radical prostatectomy (RP. The presence of circulating prostate cells (CPCs in men without evidence of BF may be useful to predict patients at risk for BF. We describe the frequency of CPCs detected after RP, relation with clinicopathological parameters, and association with biochemical failure. Methods and Patients. Serial blood samples were taken during followup after RP, mononuclear cells were obtained by differential gel centrifugation, and CPCs identified using standard immunocytochemistry using anti-PSA monoclonal antibodies. Age, pathological stage (organ confined, nonorgan confined, pathological grade, margin status (positive, negative, extracapsular extension, perineural, vascular, and lymphatic infiltration (positive, negative were compared with the presence/absence of CPCs and with and without biochemical failure. Kaplan Meier methods were used to compare the unadjusted biochemical failure free survival of patients with and without CPCs. Results. 114 men participated, and secondary CPCs were detected more frequently in patients with positive margins, extracapsular extension, and vascular and lymphatic infiltration and were associated with biochemical failure independent of these clinicopathological variables, and with a shorter time to BF. Conclusions. Secondary CPCs are an independent risk factor associated with increased BF in men with a PSA <0.2 ng/mL after radical prostatectomy, but do not determine if the recurrence is due to local or systemic disease. These results warrant larger studies to confirm the findings.

Full Text Available Objective: Diabetes mellitus Type 2 is one of the most widespread chronic metabolic diseases. In most cases, this type of diabetes is associated with alterations in levels of some inflammatory cytokines and hormones. Considering anti-inflammatory properties of plant extracts rich in ascorbic acid (vitamin C and alpha-tocopherol (vitamin E, anti-diabetic properties of these two well-known antioxidant vitamins were investigated through measurement of serum levels of high-sensitivity C-reactive protein (hs-CRP, insulin, leptin, tumor necrosis factor alpha (TNF-α, and serum amyloid A (SAA in patients with diabetes mellitus type 2. Methods: Male patients (n=80 were randomly divided into two groups each consisted of 40 subjects. Test groups were supplemented with ascorbic acid (1000 mg/day or alpha-tocopherol (300 mg/day orally during four weeks. Before and after treatment, serum biochemical factors of subjects were measured and compared. Results: Our results showed that both ascorbic acid and alpha-tocopherol could induce significant anti-inflammatory effects by decreasing the level of inflammatory factors such as TNF-α, SAA, and hs-CRP in diabetes mellitus type 2 patients. Effects of alpha-tocopherol and ascorbic acid in decreasing serum leptin level were similar. Ascorbic acid in contrast to alpha-tocopherol diminished fasting insulin and HOMA index but had no effect on LDL serum level. Conclusion: Concerning the obtained results, it is concluded that consumption of supplementary vitamins C and E could decrease induced inflammatory response in patients with diabetes mellitus type 2.  It is also possible that vitamin C and vitamin E supplementation can attenuate incidence of some proposed pathological effects of diabetes mellitus.

Full Text Available A metabonomic approach based on ultra performance liquid chromatography coupled with mass spectrometry (UPLC/MS was used to study the hepatotoxicity of ricinine in rats. Potential biomarkers of ricinine toxicity and toxicological mechanism were analyzed by serum metabonomic method. The significant differences in the metabolic profiling of the control and treated rats were clear by using the principal components analysis (PCA of the chromatographic data. Significant changes of metabolite biomarkers like phenylalanine, tryptophan, cholic acid, LPC and PC were detected in the serum. These biochemical changes were related to the metabolic disorders in amino acids and phospholipids. This research indicates that UPLC/MS-based metabonomic analysis of serum samples can be used to predict the hepatotoxicity and further understand the toxicological mechanism induced by ricinine. This work shows that metabonomics method is a valuable tool in drug mechanism study.

Full Text Available Typhoid fever causes significant biochemical changes and hepatic complications. As many studies have indicated several biochemical parameters that are involved in developing the risk of typhoid fever. The current study was designed to evaluate these risk factors in general Pakistani population. Serum biochemistry and liver enzymes were studied to investigate the relationship of these risk factors to Typhoid fever. Total 100 subjects were studied, 50 healthy individuals and 50 typhoid patients. Blood samples were collected from Allied and National Hospital, Faisalabad, Pakistan. In this study, Nested PCR was used to test the samples. Elevated level of ALT (P<0.0001 and AST (P<0.0001 were observed in typhoid patients. Typhoid patients had significantly higher concentrations of Triglyceride (P=0.0044, Globulin (P=0.0004 and Total protein (P=0.0978 while LDL (P=0.0197, Albumin (P<0.0001, Glucose (P=0.0006, HDL-cholesterol (P<0.0001 and Cholesterol (P=0.04 were significantly lower than those of healthy individuals. This study appears to be ample evidence based on the physiological and biochemical parameters in typhoid patients to explain influence of typhoid morbidity. Extensive research in this field would enable us to make modern drugs to treat typhoid fever patients.

Polycystic ovary syndrome (PCOS) is the most prevalent endocrinopathy in women of reproductive age. The study was commenced to assess the favorable effects of Rutin against metabolic, biochemical, histological, and androgenic aspects of polycystic ovary syndrome in rats. Female Sprague-Dawley rats were administered letrozole (1 mg/kg) per orally (p.o) for a period of 21 days for the induction of PCOS, followed by dose of rutin (100 mg/kg and 150 mg/kg, p.o) for 15 days using 0.5% w/v CMC as vehicle. Metformin was also given as a standard control to one of the rat groups. Serum estradiol, progesterone, testosterone, serum lipid parameters, CRP and glucose levels were evaluated. Furthermore, antioxidant activity was tested using superoxide dismutase, catalase, glutathione per-oxidase and reactive-oxygen species level. Rutin flavonoid had a dose-dependent effect on androgenic levels depicting more recovery in the rutin-I treated group, while rutin-II treated groups showed better antioxidant and lipid profiles as compared with PCOS groups. A decrease in the value of C reactive protein (CRP) and a restoration in the proportion of estrous phase smears were observed in the rutin treated groups. Histopathological examination of ovary revealed a significant decrease in the number of cystic follicles in post treated groups. The effects observed with rutin were moderately similar to that with standard metformin, a widely used treatment drug for PCOS. The study provides evidence for the potential ameliorative effects of rutin against clinical and biochemical features of PCOS.

Gallic acid has been reported to possess a number of psychopharmacological activities. These activities are attributed to the antioxidant potential due to the presence of phenolic moeity. The present study was carried out to investigate the protective effects of gallic acid in an experimental model of ketamine-induced psychosis in mice. Ketamine (50 mg/kg, i.p.) was used to induce stereotyped psychotic behavioural symptoms in mice. Behavioural studies (locomotor activity, stereotype behaviour, immobility duration and memory retention) were carried out to investigate the protective of gallic acid on ketamine-induced psychotic symptoms, followed by biochemical and neurochemical changes and cellular alterations in the brain. Chronic treatment with gallic acid for 15 consecutive days significantly attenuated stereotyped behavioural symptoms in mice. Biochemical estimations revealed that gallic acid reduced the lipid peroxidation and restored the total brain proteins. Furthermore, gallic acid remarkably reduced the dopamine levels, AChE activity and inflammatory surge (serum TNF-α), and increased the levels of GABA and increased glutathione in mice. The study revealed that gallic acid could ameliorate psychotic symptoms and biochemical changes in mice, indicating protective effects in psychosis.

Footrot is a debilitating and contagious disease in dairy cows, caused by the Gram-negative anaerobe Dichelobacter nodosus. 1 H-NMR (nuclear magnetic resonance)-based metabolomics has been previously used to understand the pathology and etiology of several diseases. The objective of this study was to characterize serum from dairy cows with footrot (n=10) using 1 H-NMR-based metabolomics and chemometric analyses. 1 H-NMR spectroscopy with multivariate pattern recognition (principal component analysis and orthogonal partial least-squares discriminant analysis) was performed to identify biomarkers in cows with footrot (F) and healthy controls (C). 1 H-NMR analysis facilitated the identification of 21 metabolites. Among these metabolites, 4 metabolites were higher and 17 metabolites were lower in the F group than in the C group. The serum levels of 5 metabolites were significantly different (Pcows with footrot have altered carbohydrate, amino acid, lipid and energy metabolic pathways. Metabolomic approaches are a clinically useful diagnostic tool for understanding the biochemical alterations and mechanisms of several diseases.

Objective: To determine the clinical value of measurement of serum cytidine deaminase (CD) levels in patients with active rheumatoid arthritis (RA). Methods: Serum levels of CD were detected with spectrophotometry, in 33 patients with active RA and 60 controls. The erythrocyte sedimentation rate (ESR) and CRP content were also determined in both groups. Results: The ser- um CD contents in patients with active RA(14.80 ± 2.11U/ml) were significantly higher than those in controls(4.86±1.86 U/ml,P<0.01). The CRP contents (51.46 ± 20.43mg/L) and ESR readings(85.03 ± 27.6mm/h) in the patients were also significantly higher than those in the controls(3.40 ± 2.21mg/L and 13.04 ± 4.89mm/h respectively, all P<0.01). In the patients, the serum CD contents were linearly positively correlated with the ESR contents and CRP readings (r=0.6324 and 0.8013 respectively, P <0.01). Conclusion: Serum CD is an early biochemical marker for diagnosis of active rheumatoid arthritis and is also of prognostic value. (authors)

The current study was conducted to evaluate the possible modulating efficacy of prolonged oral administration of clove oil against gamma irradiation-induced some biochemical disorders in male rats. Clove oil was orally administrated in a concentration of 200 mg/kg body wt daily for 21 days before irradiation at a single dose of 7 Gy and for 7 days post exposure. Transaminases (AST and ALT), alkaline phosphatase (ALP), lipid profile; cholesterol, triglycerides (T.G) and low density lipoprotein (LDL) as well as serum glucose level were determined. Also, liver reduced glutathione (GSH) content and lipid peroxidation were estimated in addition to the hepatic concentration levels of some trace elements (Fe, Cu, Zn, and Se). Rats exposed to ionizing radiation revealed transaminases disorders, lipid abnormalities, elevation in serum glucose, ALP activity as well as liver TBARS. A sharp drop in glutathione was recorded. Also, radiation induced alteration in hepatic trace element contents. The obtained data show that rats treated with clove oil before and after whole body gamma irradiation exhibited significant amelioration in liver marker enzymes, serum glucose and lipids as well as noticeable improvement in liver glutathione contents. Clove oil was also effective in minimizing lipid pr oxidation and trace element alteration induced by irradiation. It could be concluded that clove oil exerts a beneficial protective role against gamma irradiation

Full Text Available E-selectin is expressed by the activated endothelium and its plasma levels are increased in patients with systemic sclerosis. Eighteen patients fulfilling the American Rheumatism Association criteria for systemic sclerosis, 15 females and 3 males, 42-70 years old, 9 with diffuse and 9 with limited forms, were sequentially recruited for this study. Serum E-selectin levels were determined by commercially available ELISA and their association with nailfold capillaroscopic abnormalities was investigated. Nailfold capillaries were analyzed by 16X magnification wide-field capillaroscopy. Two parameters on capillaroscopy were used to correlate to serum E-selectin: deletion and ectasia. Data were analyzed statistically by the Student t-test and Spearman correlation. Two-tailed P values below 0.05 were considered significant. E-selectin range was 38 to 200 ng/ml (80 ± 39.94. There was a correlation between serum E-selectin levels and the deletion capillaroscopic score (r = 0.50, P < 0.035. This correlation was even stronger within the first 48 months of diagnosis (r = 0.63, P < 0.048. On the other hand, no association was observed between selectin and ectasia. Patients with diffuse disease presented higher serum E-selectin levels than patients with limited disease, although the difference was not statistically significant (96.44 ± 48.04 vs 63.56 ± 21.77 ng/dl; P = 0.08. The present study is the first showing a correlation between soluble serum E-selectin levels and alterations in capillaroscopy. The stronger correlation of deletion score in capillaroscopy in early disease suggests that serum E-selectin levels might be a useful biochemical marker of disease activity in systemic sclerosis.

An unknown fraction of the genome participates in the metabolism of sterols and vitamin D, two classes of lipids with diverse physiological and pathophysiological roles. Here, we used mass spectrometry to measure the abundance of >60 sterol and vitamin D derivatives in 3,230 serum samples from a well-phenotyped patient population. Twenty-nine of these lipids were detected in a majority of samples at levels that varied over thousands of fold in different individuals. Pairwise correlations between sterol and vitamin D levels revealed evidence for shared metabolic pathways, additional substrates for known enzymes, and transcriptional regulatory networks. Serum levels of multiple sterols and vitamin D metabolites varied significantly by sex, ethnicity, and age. A genome-wide association study identified 16 loci that were associated with levels of 19 sterols and 25-hydroxylated derivatives of vitamin D (P < 10(-7)). Resequencing, expression analysis, and biochemical experiments focused on one such locus (CYP39A1), revealed multiple loss-of-function alleles with additive effects on serum levels of the oxysterol, 24S-hydroxycholesterol, a substrate of the encoded enzyme. Body mass index, serum lipid levels, and hematocrit were strong phenotypic correlates of interindividual variation in multiple sterols and vitamin D metabolites. We conclude that correlating population-based analytical measurements with genotype and phenotype provides productive insight into human intermediary metabolism.

Full Text Available ABSTRACT OBJECTIVE: To compare the biochemical and immunological profiles of pediatric patients with acute myeloid leukemia (AML with healthy children and adolescents. METHODS: This was a cross-sectional study in which 21 therapy-naïve patients with AML were compared with a group of 24 healthy individuals. The following data were analyzed: serum proteins, leucocytes and subgroups, erythrocytes, hematocrit, hemoglobin, platelets, cytokines in peripheral blood mononuclear cells cultures under spontaneous and BCG- or PHA-stimulated conditions, immunoglobulin A, and erythrocytic glutathione. Statistical analysis was performed using SPSS software, considering as significant p-values < 0.05. RESULTS: Serum albumin levels were higher (p < 0.0001 in the control group, as well as all the parameters related to red blood cells (p < 0.0001. For leucocytes and subgroups, no statistical difference was found between the AML and the control groups. For cytokines, the concentrations were significantly higher under spontaneous and BCG-stimulated conditions for TNF-a, IL-6, IL-10, and IFN-? in the control group. Under PHA-stimulated conditions, the concentration was higher (p = 0.002 only for IL-6. No difference was found between the two groups for the other cytokines and for IgA in the saliva. Erythrocytic glutathione was higher (p < 0.0001 in AML patients. CONCLUSIONS: It was possible to characterize the biochemical and immunological profile of pediatric patients with AML, as well as highlight some significant differences in these parameters when comparing with healthy children and adolescents.

Full Text Available Background: Individual variation of examination performance depends on many modifiable and non-modifiable factors, including pre-examination anxiety. Medical students’ quality of life (QoL and certain biochemical changes occurring while they are preparing for examinations has not been explored. Purpose: We hypothesize that these parameters would determine the examination performance among medical students. Methods: Fourth-year medical students (n=78 from the University of Ruhuna, Sri Lanka, were invited. Their pre- and post-exam status of QoL, using the World Health Organization Quality of Life (WHOQOL-BREF questionnaire, and the level of biochemical marker levels (i.e., serum levels of thyroid profile including thyroglobulin, cortisol and ferritin were assessed. Differences between the scores of QoL and serum parameters were compared with their performance at the examination. Results: The mean QoL score was significantly lower at pre-exam (56.19±8.1 when compared with post-exam (61.7±7.1 levels (p<0.001. The median serum TSH level prior to the exam (0.9 mIU/L; interquartile range 0.74–1.4 mIU/L was significantly lower (p=0.001 when compared with the level after the exam (median of 2.7 mIU/L; IQR 1.90–3.60. The mean±SD fT4 level was significantly higher before the exam (19.48±0.4 pmol/L at study entry vs. 17.43±0.3 pmol/L after the exam; p<0.001. Median serum ferritin (SF level prior to the exam (43.15 (23.5–63.3 µg/L was significantly lower (p≤0.001 when compared with after-exam status (72.36 (49.9–94.9 µg/L. However, there was no difference in mean serum cortisol levels (16.51±0.7 at pre-exam and 15.88±0.7 at post-exam, respectively; p=0.41. Conclusions: Students had higher fT4 and low ferritin levels on pre-exam biochemical assessment. It was evident that students who perform better at the examination had significantly higher QoL scores at each domain tested through the questionnaire (Physical health, Psychological

2010-01-01

Background: Hepatitis C is a common and important cause of chronic liver disease that often remains asymptomatic and most of the times discovered incidentally by routine serologic or biochemical testing. Aminotransferases (AST and ALT) reflect alterations in liver function/inflammation in liver diseases. The current study was conducted to examine the utilization and limitations of these biochemical markers in subjects with asymptomatic HCV infection. Aims and Objectives: To find out how many subjects with asymptomatic HCV infection have normal or elevated serum AST and ALT levels. Subjects and Methods: Study Design: Cross sectional. Study Duration: Seven months from November 2008 to July 2009. Study Universe: Services Hospital, Lahore. Study Population: This study included 413 subjects attending the outpatient departments of hospital with minor complaints. The random population of subjects was referred to the clinical laboratory of Services Hospital, Lahore for LFTs, HBsAg and anti-HCV screening from OPD department of the hospital. A total of 413 persons of all ages were analyzed during this study. There were 263 subjects who were sero - positive for anti-HCV (141 females, 122 males; median age 35 +- 11.34 years) and 150 in the control group (80 of them were females and 70 males with median age 32 +- 12.97 years) were sero-negative for both HBsAg and anti - HCV. Subjects Selection Criteria: In this study, only anti - HCV sero - positive subjects were included who was sero - negative for HBsAg or dual infection (both HBsAg and anti - HCV) and not on anti - viral therapy. Control group was sero - negative for both - HBsAg and anti - HCV antibodies. Data Collection: We assayed levels of serum aminotransferases (AST and ALT) and screened blood for HBsAg and anti-HCV. ELISA technique was used for viral hepatitis markers. Results: Out of 263 subjects tested positive for anti-HCV antibodies in their blood, 90.76 % and 87.45 % had elevated AST and ALT levels (ALT = 40 U

Developing host digestion-resistant starches to promote human health is of great research interest. Chemically modified starches (CMS) are widely used in processed foods and although the modification of the starch molecule allows specific reduction in digestibility, the metabolic effects of CMS have been less well described. This short-term study evaluated the impact of enzymatically modified starch (EMS) on fasting and postprandial profiles of blood glucose, insulin and lipids, and serum metabolome in growing pigs. Eight jugular-vein catheterized pigs (initial body weight, 37.4 kg; 4 months of age) were fed 2 diets containing 72% purified starch (EMS or waxy corn starch (control)) in a cross-over design for 7 days. On day 8, an 8-hour meal tolerance test (MTT) was performed with serial blood samplings. Besides biochemical analysis, serum was analysed for 201 metabolites through targeted mass spectrometry-based metabolomic approaches. Pigs fed the EMS diet showed increased (Pmetabolome profiling identified characteristic changes in glycerophospholipid, lysophospholipids, sphingomyelins and amino acid metabolome profiles with EMS diet compared to control diet. Results showed rapid adaptations of blood metabolites to dietary starch shifts within 7 days. In conclusion, EMS ingestion showed potential to attenuate postprandial raise in serum lipids and suggested constant alteration in the synthesis or breakdown of sphingolipids and phospholipids which might be a health benefit of EMS consumption. Because serum insulin was not lowered, more research is warranted to reveal possible underlying mechanisms behind the observed changes in the profile of serum lipid metabolome in response to EMS consumption.

Full Text Available Abstract Background Intrinsic fluctuations due to the stochastic nature of biochemical reactions can have large effects on the response of biochemical networks. This is particularly true for pathways that involve transcriptional regulation, where generally there are two copies of each gene and the number of messenger RNA (mRNA molecules can be small. Therefore, there is a need for computational tools for developing and investigating stochastic models of biochemical networks. Results We have developed the software package Biochemical Network Stochastic Simulator (BioNetS for efficientlyand accurately simulating stochastic models of biochemical networks. BioNetS has a graphical user interface that allows models to be entered in a straightforward manner, and allows the user to specify the type of random variable (discrete or continuous for each chemical species in the network. The discrete variables are simulated using an efficient implementation of the Gillespie algorithm. For the continuous random variables, BioNetS constructs and numerically solvesthe appropriate chemical Langevin equations. The software package has been developed to scale efficiently with network size, thereby allowing large systems to be studied. BioNetS runs as a BioSpice agent and can be downloaded from http://www.biospice.org. BioNetS also can be run as a stand alone package. All the required files are accessible from http://x.amath.unc.edu/BioNetS. Conclusions We have developed BioNetS to be a reliable tool for studying the stochastic dynamics of large biochemical networks. Important features of BioNetS are its ability to handle hybrid models that consist of both continuous and discrete random variables and its ability to model cell growth and division. We have verified the accuracy and efficiency of the numerical methods by considering several test systems.

Full Text Available Abstract. The purpose of the present studywas to investigate some basic biochemical and chemical parameters of pikeperch (Sander lucioperca L. yearlings reared in ponds after wintering. The investigation has been carried out in the Institute of Fisheries and Aquaculture, Plovdiv. The fish included in the study were randomly selected from one pond, with area of 0.40 ha. Blood samples were collected from 10 pikeperches with average weight from 80 to 100 g. Blood biochemical parameters were individually analysed. For hemoglobin determination, blood was anticoagulated with sodium citrate. Samples for body tissue о analysis (without the head and viscera were collected from 4 fish, autoclaved and used for analysis of water content, % (drying at 105 С, 24 h; Bulgarian State Standard – SR ISO 5984, protein content, % (Kjeldahl method, Bulgarian State Standard – SR ISO 5983 semi-automated DK 6 digester unit and UDK 132 o distillation system, Velp Scientifica, fats (% by the method of Smidt-Boudzynski Ratzlaff and ash (% by burning in a muffle furnace at 550 С, BSS – SR ISO -1 -1 -1 6496. The average blood serum total protein was 66.1±0.12 g.l , blood glucose concentration was 92.8±3.42 mg.100 ml (5.15 mmol.l and average -1 hemoglobin content was 44.7±0.33 g.l . The average protein content in analysed fish samples was 16.65±0.23 %. Protein content was the highest among studied dry matter components, followed by the ash (1.97±0.06 % and fat content (0.84±0.03 %. The levels of blood serum total protein, blood glucose and hemoglobin content as well as body composition parameters - water, protein, fat and ash of pikeperch fingerlings (Sander lucioperca L. after wintering reflect the specific equilibrium of plastic and energy substances after the winter period, with no deviations from the reference ranges.

Biochemical variables in blood were measured in venous blood samples from 38 to 72 Space Shuttle astronauts before and immediately after flights of 2 to 11 days. Mean pre- and postflight values were compared using the paired t-test or the Wilcoxon signed-rank test. The largest change in serum enzymes was a 21% increase (P = .0014) in gamma-glutamyl-transpeptidase, which may have been related to stress. The median value of apolipoprotein (apo) A-I decreased from 152 to 127 mg/dL (P < .0001), but the change in apo B (77 to 73 mg/dL) was not statistically significant, and the mean apo A-I/apo B ratio remained well above 1.5. A decrease in dietary fat and cholesterol intake during shuttle missions may have been a cause of the change in apo A-I. Twelve of the 16 nonenzyme serum proteins measured were significantly elevated (P < .05), possibly because of hemoconcentration and increased protein catabolism. The 56% increase in haptoglobin may be related to release of suppressed erythropoiesis at landing.

Frequent outbreaks of Sarcoptes scabiei infestation in raccoon dogs (Nyctereutes procyonoides) have been reported in Japan. Although many raccoon dogs are brought to Kanazawa Zoological Garden (Yokohama, Kanagawa, Japan) because of S. scabiei infestation and debilitation, some of them die of asthenia. The clinical status of severely debilitated raccoon dogs must be determined to save their lives. In this study, we compared hematological and serum biochemical values between severely debilitated and nondebilitated raccoon dogs infested with S. scabiei. The total protein, albumin, glucose, and calcium values of debilitated raccoon dogs were significantly lower than those of nondebilitated raccoon dogs. On the other hand, debilitated raccoon dogs had significantly higher aspartate aminotransferase, total bilirubin, blood urea nitrogen, sodium, chloride, and phosphorus values than did nondebilitated raccoon dogs. The increase in the blood urea nitrogen value was particularly dramatic. The present study revealed that debilitated raccoon dogs infested with S. scabiei exhibited abnormal hematological values compared with nondebilitated raccoon dogs infested with S. scabiei. Clinically, the raccoon dogs developed malnutrition and sepsis if the mange infestation was untreated. Moreover, dehydration associated with appetite loss may have resulted in insufficient renal perfusion. These findings suggest that chronic S. scabiei infestations debilitated the raccoon dogs and resulted in physiological changes that were detected with hematological and serum biochemical tests.

Our primary aim was to investigate whether N-terminal pro-brain natriuretic peptide (NT-proBNP) increases in adolescent with polycystic ovary syndrome (PCOS) compared with healthy controls and secondary aim was to determine whether metabolic and hormonal differences exist between groups. In this cross-sectional study, 25 adolescent patients with PCOS and 25 normal ovulatory control not suffering from PCOS were involved in the study. Fasting serum NT-proBNP, C-reactive protein (CRP), homocystein, insulin levels and biochemical and hormonal parameters were measured. Serum NT-proBNP was not significantly different in PCOS subjects (0.62 ± 0.80 vs 1.12 ± 1.51 ng/mL, p = 0.154). The mean serum fasting insulin levels (22.64 ± 10.51 vs 13.32 ± 3.97 mIU/mL, p = 0.001) and Homeostasis Model Assessment Insulin-Resistance Index (HOMA-IR) levels (5.16 ± 1.81 vs 2.97 ± 0.89, p = 0.001) were significantly high in the study group. The median serum CRP levels were not significantly different between groups (1 [1-12] vs 1 [1-19] g/dL, p = 0.286). The present study demonstrated that the levels of BNP, CRP and homocystein were not different in PCOS subjects. Serum insulin levels and HOMA-IR were significantly higher in PCOS subjects. Possible serum markers for PCOS-related metabolic abnormalities and cardiovascular events, may not present in the adolescent years.

We have assessed the effect of elevated concentrations of homogentisic acid (HGA) as in alkaptonuria (AKU), on a range of routine chemistry tests in serum and urine. HGA was added to pooled serum and a range of assays was analysed with Roche Modular chemistries. Effects on urine were assessed by diluting normal urine with urine from a patient with AKU, adding HGA to urine and after lowering output of urinary HGA with nitisinone treatment. Serum enzymatic creatinine showed 30% negative interference with 100μmol/L HGA and >50% at 400μmol/L. Serum urate 100 to 480μmol/L was reduced up to 20% at 100 and to 50% with 400μmol/L HGA. Serum cholesterol between 3 and 11mmol/L was reduced by 0.5mmol/L with 400μmol/L HGA. Urine enzymatic creatinine and urate with >2mmol/L HGA showed concentration dependent negative interference up to 80%. A positive interference in urine total protein by benzethonium turbidometric assay was observed, with 10mmol/L HGA equivalent to 1g/L protein. Jaffe creatinine, Na, K, Cl, Mg, Ca, phosphate, ALT, GGT, ALP activities and urea in serum and or urine were not affected by increases in HGA. To avoid interferences by HGA in alkaptonuria concentration of HGA should be established before samples are assayed with peroxidase assays and benzethonium urine protein.

Exercise stimulates a dramatic change in the concentration of circulating hormones, such as growth hormone (GH), but the biological functions of this response are unclear. Pharmacological GH administration stimulates collagen synthesis; however, whether the post-exercise systemic milieu has a similar action is unknown. We aimed to determine whether the collagen content and tensile strength of tissue-engineered ligaments is enhanced by serum obtained post-exercise. Primary cells from a human anterior cruciate ligament (ACL) were used to engineer ligament constructs in vitro. Blood obtained from 12 healthy young men 15 min after resistance exercise contained GH concentrations that were ∼7-fold greater than resting serum (P Ligament constructs were treated for 7 days with medium supplemented with serum obtained at rest (RestTx) or 15 min post-exercise (ExTx), before tensile testing and collagen content analysis. Compared with RestTx, ExTx enhanced collagen content (+19%; 181 ± 33 vs. 215 ± 40 μg per construct P = 0.001) and ligament mechanical properties - maximal tensile load (+17%, P = 0.03 vs. RestTx) and ultimate tensile strength (+10%, P = 0.15 vs. RestTx). In a separate set of engineered ligaments, recombinant IGF-1, but not GH, enhanced collagen content and mechanics. Bioassays in 2D culture revealed that acute treatment with post-exercise serum activated mTORC1 and ERK1/2. In conclusion, the post-exercise biochemical milieu, but not recombinant GH, enhances collagen content and tensile strength of engineered ligaments, in association with mTORC1 and ERK1/2 activation. © 2015 The Authors.

1992-01-01

Mononuclear (MNC) and polymorphonuclear cell (PMNC) zinc content was determined together with serum zinc, copper, selenium and iron concentrations in 24 operable breast cancer patients during and after postoperative radiotherapy. Anthropometric and biochemical indices of nutritional status were measured as background data. The measurements were carried out in the years 1987-1988. Nine patients used unconventional multivitamin or trace element preparations. A steady but statistically insignificant decrease in PMNC zinc was seen during treatment. No changes occurred in MNC zinc. Serum copper levels increased in five patients possibly due to tamoxifen treatment, but no other alterations occurred in serum trace element levels. Appetite was well maintained and nutritional status remained unaltered. Postoperative radiotherapy for breast carcinoma had thus no effect on either trace element or nutritional status. Patient-initiated alternative treatments did not significantly affect their trace element levels. This was probably due to small supplementation doses or irregular use of the preparations. (orig.)

The interassay variability found in the measurement of testosterone (T) levels warrants the need for laboratories to validate their methods to establish trustworthy cut-off points for diagnosis of male hypogonadism. The aims of this study were to validate measurement of total T (TT) at our laboratory in order to obtain reference ranges for TT, calculated free T (CFT), calculated bioavailable T (CBT), and salivary T (ST) in healthy young men from the Mediterranean region, and to evaluate the potential clinical value of ST by establishing its correlation with serum T. An observational, cross-sectional study with sequential sampling. men aged 18-30 years with body mass index (BMI)9.7 nmol/L, CFT>0.22 nmol/L, and/or CBT>4.9 nmol/L make the presence of biochemical hypogonadism unlikely. According to the correlation between serum and ST, the clinical value of ST remains to be established. Copyright © 2014 SEEN. Published by Elsevier Espana. All rights reserved.

Full Text Available Introduction: This study aimed to investigate the relationship between serum adiponectin and metabolic syndrome in adults living in rural Malaysia. Methods: A total of 299 Malay adults (men=124; women = 175 with a mean age 48.8 (11.7 years were recruited. Measurements for waist circumference and blood pressure were taken before drawing an overnight fasting blood samples. Biochemical tests for triglycerides, HDL cholesterol, glucose and serum adiponectin concentration were measured. Results: Our results show that the adiponectin level in the subjects with metabolic syndrome was significantly lower than those without metabolic syndrome (p < 0.05. Among the metabolic syndrome risk factors, adiponectin level was significantly associated with hypertriglyceridemia and reduced HDL cholesterol (p < 0.001. Conclusion: The outcome from this study which highlights the association of hypoadiponectinemia with risk factors of metabolic syndrome in Malay adults, suggests that the reduced level of adiponectin may play a pivotal role in the development of metabolic syndrome in this ethnic group.

Full Text Available Nonalcoholic fatty liver disease (NAFLD, tightly linked to the metabolic syndrome (MS, has emerged as a leading cause of chronic liver disease worldwide. Since it is potentially progressive towards non-alcoholic steatohepatitis (NASH and hepatic fibrosis, up to cirrhosis and its associated complications, the need for predictive factors of NAFLD and of its advanced forms is mandatory. Despite the current “gold standard” for the assessment of liver damage in NAFLD being liver biopsy, in recent years, several non-invasive tools have been designed as alternatives to histology, of which fibroscan seems the most promising. Among the different serum markers considered, serum uric acid (SUA and ferritin have emerged as possible predictors of severity of liver damage in NAFLD. In fact, as widely described in this review, they share common pathogenetic pathways and are both associated with hepatic steatosis and MS, thus suggesting a likely synergistic action. Nevertheless, the power of these serum markers seems to be too low if considered alone, suggesting that they should be included in a wider perspective together with other metabolic and biochemical parameters in order to predict liver damage.

Full Text Available The effects of dietary inclusion of sugar syrup on quality of egg, cholesterol level, production performance, serum total protein and blood biochemical parameters were evaluated in laying hens. A total of 300 commercial Lohmann LSL hens (30 weeks of age were randomly distributed into 3 dietary treatments which consisted of a normal corn diet containing corn–soy and 2 diets containing 5% and 10% sugar syrup. Each treatment was replicated 5 times (n = 20. Egg production, feed intake, body weight and egg weight of laying hens fed different diets were recorded. The experiment lasted for 20 weeks. The Haugh unit scores of hens fed diets with sugar syrup were significantly increased (P < 0.05 compared with the control treatment. The sugar syrup had no significant effect on liver enzymes, total protein, blood glucose and creatinine in all treatments. The eggs laid by hens fed sugar syrup diets had lower cholesterol level (P < 0.05 compared with those laid by hens fed the control diet. Electrophoresis analysis showed that comparable electrophoretic patterns were noticed between serum proteins of treatment groups. From the results, it can be concluded that sugar syrup diets and corn diets have similar effects on feed intake, body weight, production of eggs and blood biochemical parameters in layer hens, which suggests sugar syrup can be used as an energy source for replacing part of corn in poultry layer diets.

Full Text Available In the article data are presented on dynamics of the level of indicators of metabolic profile of blood serum of race horses of the Ukrainian riding breed in the conditions of physical and emotional loading. Clinically healthy race horses were the object of  research. Blood was taken from the jugular vein to obtain serum and for further biochemical research. For the research 12 race horses from a training group were chosen. From time to time the animals took part in competitions; they were not specially used in races and were mostly used for the training of junior riders and sportsmen of different levels. Blood was taken in conditions of relative rest after ordinary training and after emotional stress during the entertainment performances when a large number of people were present and loud music was played. In the blood serum the following biochemical indicators were defined: whole protein, urea, creatinine, uric acid, total bilirubin and its fractions, glucose, cholestererol, triacylglycerol, calcium, ferrum, lactate, pyruvate, activity of the AlAT, SGOT, GGTP, LDH, an alkaline phosphatase – which makes it possible to determine reasonably accurately the adaptation potential of a horse under various types of loading. We established that during training and psychoemotional loading of racing horses of the training group of the Ukrainian riding breed, multidirectional changes in the level of biochemical indicators of blood serum occurred, which is evidence of stress in the metabolic processes in the animals’ organisms. Concentration of a biomarker of an oxidative stress, uric acid, increased after physical loading by 8.6%, and after emotional loading by 55.1%, which demonstrates that emotional stress had the more negative effect, indicating insufficient adaptation by the horses before demonstration performances. After physical loading, reaction of transamination in the horses’ liver cells intensified, and after emotional loading its intensity

Nutritional Habits have changed significantly and junk foods have become widely popular, in recent years. The present study aimed to shed the light on the effect of potato chips and / or ketchup consumption on some biochemical parameters. Sixty four male and female albino rats were used in the study. Animals were maintained on 0.25 g potato chips/ rat and / or 0.125 g ketchup / rat, 5 days a week for 4 weeks. Potato chips showed the lowest body wt gain in the male rats after 4 weeks but, ketchup modulated this negative effect of the potato chips in the group of male animals fed on potato chips plus ketchup. Potato chips significantly decreased brain serotonin, liver glutathione (GSH) and catalase (CAT) in both sexes; brain dopamine, serum total proteins, albumin, total globulins, α 2 - and β 1 -globulins in the females and serum thyroxine (T 4 ) in the male rats. Ketchup apparently affected serum T 4 and A / G ratio in both sexes, brain dopamine and liver GSH in the males in addition to brain serotonin, serum total globulins and ?1-globulin in the female rats. Potato chips plus ketchup significantly changed T 4 , dopamine, GSH, CAT, α 1 and α 2 -globulins in both sexes; serotonin and β 1 -globulin in the male rats, total proteins and albumin in the females. It could be concluded that potato chips consumption might induce numerous adverse effects in various body organs

Full Text Available BACKGROUND Smoking is one of the most common addictions of modern times and needs to be studied in a community as a public health issue. Also, smoking is a modifiable risk factor for type-2 DM. The smoking-related diseases share common pathophysiologies of imbalance of systemic oxidants and antioxidant status, increased inflammatory reactions, insulin resistance and dyslipidaemia. Biochemical assay of serum Gamma-Glutamyl Transferase (GGT activity is a low cost and highly sensitive laboratory test. Studies have indicated GGT is moderately elevated before the onset of other traditional risk factors for type-2 DM. So, among hepatic markers, the baseline GGT analysis can be an early risk marker of type 2 diabetes in cigarette smokers has to be studied. MATERIALS AND METHODS This is a case-control study on male cigarette smokers. 57 smokers were studied clinically and biochemically for plasma insulin, glucose and liver enzymes including GGT using standard biochemical methods and compared with 42 age and sex matched non-smokers as controls. RESULTS The mean serum GGT in smokers (25.45 ± 10.8 was increased compared to non-smokers (18.8 ± 5.8. Smokers GGT (r=0.396 and HOMA-IR (r=0.352 showed significant positive association with duration of smoking (p24 IU/L. Regression analysis showed none of the diabetic risk factors were observed to be dependent on GGT including other liver enzymes. Regression analysis showed GGT is not an independent risk factor for DM. Although, the mean fasting blood glucose (91.4 ± 21.3, BMI (26.1 ± 9.3 and HOMA-IR (7.3 ± 2.3 was increased among cigarette smokers with GGT >24 IU/L. CONCLUSION The baseline GGT assay in cigarette smokers might be associated with the proinflammatory status or be a marker of oxidative stress of smoke toxins. Smokers with baseline GGT >24 IU/L develop insulin resistance should be investigated in future longitudinal studies for prediabetes to consider cigarette smoking as an important modifiable

Recently, an isolated population of apparent GH-receptor deficient (GHRD) patients has been identified in the Loja province of southern Ecuador. These individuals presented many of the physical and biochemical phenotypes characteristic of Laron-Syndrome and are believed to have a defect in the GH-receptor gene. In this study, we have compared the biochemical phenotypes between the affected individuals and their parents, considered to be obligate heterozygotes for the disorder. Serum GH, insulin-like growth factor I and II (IGF-I and IGF-II) levels were measured by RIA Insulin-like growth factor binding proteins. (IGFBPs) were measured by Western ligand blotting (WLB) of serum samples, following separation by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and relative quantitation of serum IGFBPs was performed with a scanning laser densitometer. Serum GH-binding protein (GHBP) levels were measured with a ligand-mediated immunofunctional assay using a monoclonal antibody raised against the GHBP. These values were then compared to values obtained from normal, sex-matched adult Ecuadorian controls, to determine if the above parameters were abnormal in the heterozygotes. The serum IGF-I levels of the GHRD patients were less than 13% of control values for adults and 2% for children. However, the IGF-I levels of both the mothers and fathers were not significantly different from that of the control population. The serum IGF-II levels of the GHRD patients were approximately 20% of control values for adults and 12% for the children. The IGF-II levels of the mothers were reduced, but were not significantly different from that of the control population. However, IGF-II levels of the fathers were significantly lower than those of controls (64% of control male levels). WLB analysis of serum IGFBP levels of the affected subjects demonstrated increased IGFBP-2 and decreased IGFBP-3, suggesting an inverse relationship between these IGFBPs. The GHRD patients who had the

Hyperlipidemia is one of the famous disorders that can lead to atherosclerosis. Garlic has been considered as one of the blood lipids lowering agents for ages, and various studies have been carried out, some of them confirmed this effect of garlic and some did not. The aim of this study was to evaluate the effect of raw garlic consumption on human blood biochemical factors in hyperlipidemic individuals. This clinical trial was conducted on 30 volunteer individuals with blood cholesterol higher than 245 mg/dl. Fasting blood samples were collected for biochemical tests. The volunteers consumed 5 g raw garlic twice a day for 42 days. Second fasting blood samples were collected and the individuals did not use any kind of garlic for next 42 days. After that, the third fasting blood samples were collected and the biochemical factors were measured. After 42 days of garlic consumption the mean of blood total cholesterol (pconsumption total cholesterol (pconsumption alone can decrease serum lipids, but it cannot be used as the main therapeutic agent for hyperlipidemia. Garlic can be used in mild hyperlipidemia or when the patients cannot tolerate the chemical drugs.

Full Text Available Aspartame (ASP is one of the most widely used nonnutritive sweeteners. This study investigates the chronic effects of ASP on hematological and biochemical parameters, and its effects on the oxidative/antioxidative status in the red blood cells of Wistar albino rats. Rats were provided with ASP (40 mg/kg/daily for six weeks in drinking water. Increased food and fluid intake was observed in the ASP-treated rats. Total body mass was significantly decreased in the ASP-treated rats. Treatment with ASP caused an increase in the concentrations of glucose, cholesterol, LDL-cholesterol, and in the activities of alanine aminotransferase (ALT, aspartate aminotransferase (AST and lactate dehydrogenase (LDH, as well as a decrease in the levels of HDL-cholesterol in the serum. A significant decline in the number of white blood cells (WBC was observed after ASP uptake. Based on the results we conclude that ASP induces oxidative stress, observed as an alteration of the glutathione redox status, which leads to increased concentrations of nitric oxide (NO and lipid peroxides (LPO in the red blood cells. Changes in biochemical parameters, lipid metabolism, as well as changes in the levels of oxidative stress markers and the appearance of signs of liver damage indicate that chronic use of ASP can lead to the development of hyperglycemia, hypercholesterolemia and associated diseases.

Mutations in the GALNT3 gene cause tumoral calcinosis characterized by ectopic calcifications due to persistent hyperphosphatemia. We recently developed Galnt3 knockout mice in a mixed background, which had hyperphosphatemia with increased bone mineral density (BMD) and infertility in males. To test the effect of dietary phosphate intake on their phenotype, Galnt3 knockout mice were generated in the C57BL/6J strain and fed various phosphate diets: 0.1% (low), 0.3% (low normal), 0.6% (normal), and 1.65% (high). Sera were analyzed for calcium, phosphorus, alkaline phosphatase, creatinine, blood urine nitrogen, 1,25-dihydroxyvitamin D, osteocalcin, tartrate-resistant acid phosphatase 5b, and fibroblast growth factor 23 (Fgf23). Femurs were evaluated by dual-energy x-ray absorptiometry, dynamic histomorphometry, and/or microcomputed tomography. Galnt3 knockout mice in C57BL/6J had the same biochemical phenotype observed in our previous study: hyperphosphatemia, inappropriately normal 1,25-dihydroxyvitamin D level, decreased alkaline phosphatase activity, and low intact Fgf23 concentration but high Fgf23 fragments. Skeletal analyses of their femurs revealed significantly high BMD with increased cortical bone area and trabecular bone volume. On all four phosphate diets, Galnt3 knockout mice had consistently higher phosphorus levels and lower alkaline phosphatase and intact Fgf23 concentrations than littermate controls. The low-phosphate diet normalized serum phosphorus, alkaline phosphatase, and areal BMD but failed to correct male infertility in Galnt3 knockout mice. The high-phosphate diet did not increase serum phosphorus concentration in either mutant or control mice due to a compensatory increase in circulating intact Fgf23 levels. In conclusion, dietary phosphate restriction normalizes biochemical and skeletal phenotypes of Galnt3 knockout mice and, thus, can be an effective therapy for tumoral calcinosis.

To compare the biochemical and immunological profiles of pediatric patients with acute myeloid leukemia (AML) with healthy children and adolescents. This was a cross-sectional study in which 21 therapy-naïve patients with AML were compared with a group of 24 healthy individuals. The following data were analyzed: serum proteins, leucocytes and subgroups, erythrocytes, hematocrit, hemoglobin, platelets, cytokines in peripheral blood mononuclear cells cultures under spontaneous and BCG- or PHA-stimulated conditions, immunoglobulin A, and erythrocytic glutathione. Statistical analysis was performed using SPSS software, considering as significant p-values<0.05. Serum albumin levels were higher (p<0.0001) in the control group, as well as all the parameters related to red blood cells (p<0.0001). For leucocytes and subgroups, no statistical difference was found between the AML and the control groups. For cytokines, the concentrations were significantly higher under spontaneous and BCG-stimulated conditions for TNF-α, IL-6, IL-10, and IFN-γ in the control group. Under PHA-stimulated conditions, the concentration was higher (p=0.002) only for IL-6. No difference was found between the two groups for the other cytokines and for IgA in the saliva. Erythrocytic glutathione was higher (p<0.0001) in AML patients. It was possible to characterize the biochemical and immunological profile of pediatric patients with AML, as well as highlight some significant differences in these parameters when comparing with healthy children and adolescents.

Objective: To study the effect of anesthesia on changes of serum NO and TNF-α levels in surgical patients. Methods: Serum NO (with biochemical method) and TNF-α (with RIA) levels were determined for 3 times in 31 patients operated under regional anesthesia and 31 patients operated under general anesthesia (both for benign gastric ulcer). The levels were measured before induction of anesthesia, at the beginning of operation, and 1 hr later. Results: In patients under regional anesthesia, both the NO and TNF-α levels increased significantly at the beginning of operation and, 1 hr later, though dropped, remained significantly higher than the levels before induction (P<0.05). NO significant changes of the levels were observed in patients under general anesthesia throughout the operation, and the levels were, as a whole, significantly lower than the levels under regional anesthesia (P<0.05). Conclusion: General anesthesia (combined intravenous and inhalation) could abolish the increase of serum NO and TNF-α levels duning operation. (authors)

Purpose: To quantify the correlation between fat content of an acute alcohol intoxication and the difference of computer tomography attenuation value in dual-energy CT in comparison to biochemical triglyceride analysis and to evaluate qualitatively the value of DECT in the diagnosis of fatty liver caused by ethanol-dosage in rats. Materials and Methods: DECT at 140 kV and 80 kV was performed on 20 rats before and two days after the administration of 3 ml of 50 % ethanol. The CT attenuation value in the livers at 140 kV, 80 kV and the differences between them in Hounsfield units (ΔH) were collected. Parts of the liver (100 mg) were measured in biochemical triglyceride analysis as the reference standard. A blood sample was also taken to measure specific liver enzymes. Results: Linear correlation between biochemical triglyceride analysis and CT density of ΔH was found (r = 0.949). 140 kV attenuation data were between 44 HU and 61.3 HU, 80 kV attenuation data were between 58.4 HU and 64.7 HU, and ΔH data were between 3.4 HU and 14.4 HU (p ≤ 0.037). The biochemical triglyceride analysis data were between 7.1 mg/g and 41.1 mg/g. The hepatic enzymes serum aspartate (ASAT) aminotransferase and alanine aminotransferase (ALAT) were elevated in all rats. ASAT correlated directly with ΔHU (r = -0.86). Conclusion: DECT provides a non-invasive method to determine and evaluate hepatic fat content after acute alcohol intoxication. It provides the possibility to detect and quantify the hepatic fat content of liver graft. (orig.)

To determine the associations between apolipoprotein E (APOE) genotypes and serum levels of glucose, total cholesterol, and triglycerides in a cognitively normal aging Han Chinese population. There were 1,003 cognitively normal aging subjects included in this study. APOE genotypes were analyzed and biochemical parameters were tested. All the subjects were divided into three groups according to APOE genotypes: (1) E2/2 or E2/3 (APOE E2); (2) E3/3 (APOE E3); and (3) E2/4, E3/4, or E4/4 (APOE E4). Correlations of serum levels of glucose, total cholesterol, and triglycerides with APOE genotypes were assessed. E2, E3, and E4 allele frequencies were found to be 6.2%, 82.1%, and 11.7%, respectively. Serum levels of total cholesterol were higher in the APOE E4 group (Ptriglycerides (adjusted odds ratio 1.042, 95% confidence interval 0.759-1.429, P=0.800). A higher serum level of total cholesterol was significantly correlated with APOE E4 status in a cognitively normal, nondiabetic aging population. However, there was no correlation between APOE genotypes and serum levels of glucose or total triglycerides.

Full Text Available Abstract Background There is an increasing interest to model biochemical and cell biological networks, as well as to the computational analysis of these models. The development of analysis methodologies and related software is rapid in the field. However, the number of available models is still relatively small and the model sizes remain limited. The lack of kinetic information is usually the limiting factor for the construction of detailed simulation models. Results We present a computational toolbox for generating random biochemical network models which mimic real biochemical networks. The toolbox is called Random Models for Biochemical Networks. The toolbox works in the Matlab environment, and it makes it possible to generate various network structures, stoichiometries, kinetic laws for reactions, and parameters therein. The generation can be based on statistical rules and distributions, and more detailed information of real biochemical networks can be used in situations where it is known. The toolbox can be easily extended. The resulting network models can be exported in the format of Systems Biology Markup Language. Conclusion While more information is accumulating on biochemical networks, random networks can be used as an intermediate step towards their better understanding. Random networks make it possible to study the effects of various network characteristics to the overall behavior of the network. Moreover, the construction of artificial network models provides the ground truth data needed in the validation of various computational methods in the fields of parameter estimation and data analysis.

The study was conducted on 24 patients who received 15 mg daily doses of sibutramine for 12 weeks, and on 20 patients who received placebo. At the baseline, after the sixth and twelfth weeks of treatment, body weight and blood pressure were measured, the BMI was calculated, and samples of blood and of first morning urine were collected. Serum lipid profiles, glucose levels, and nitric oxide levels were determined. The iron (Fe), copper (Cu), zinc (Zn), calcium (Ca), and magnesium (Mg) present in the serum and urine samples were assessed. The erythrocyte hemolysate of the patients was use to assay the activity of glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD). No changes were observed in BMI, blood pressure, or nitric oxide during the study. After 12 weeks of treatment, a decrease was observed in total cholesterol, LDL cholesterol, triglyceride, glucose, and ferritin levels. GSH-Px and SOD activity increased after 12 weeks of sibutramine treatment. The Mg and Cu increases was observed in serum after the sixth and twelfth weeks of treatment. It was found that the Zn level decreased in serum after the twelfth week. The elimination of Ca, Mg, Fe, Zn, and Cu in urine also declined in the twelfth week. No differences were found in the women taking the placebo. In conclusion, we found that sibutramine had a positive effect on lipid and glucose status in obese women. However, the drug disturbed the balance of minerals, especially Zn and Mg, in the subjects.

Ursodeoxycholic acid (UDCA) is commonly used for the treatment of hepatobiliary disease. UDCA is a bile acid that can be detected in the bile acid assay. Its effect on biochemical analytes is unknown. The aim of this study was to determine the effect of 6-8 weeks of UDCA administration on fasting and postprandial concentrations of serum bile acids (SBA), cholesterol, triglycerides, bilirubin, and liver enzyme activities in healthy dogs. Twenty healthy dogs received UDCA for 6-8 weeks. CBC, biochemistry profile, urinalysis, fasting and postprandial SBA, and hepatobiliary ultrasound examination were performed prior to starting UDCA (timepoint 0) and after 6-8 weeks of therapy, while animals were still receiving UDCA (timepoint 1). Timepoint 0 and timepoint 1 values were compared with a paired t-test. SBA were remeasured 72 hours after UDCA discontinuation. Only mean fasting SBA at timepoint 1 increased significantly (P = .03) from timepoint 0 (2.26 μmol/L at time 0 and 3.81 μmol/L at time 1) but were not elevated above the normal reference interval (0-9 μmol/L). Two dogs had timepoint 1 fasting SBA above the reference interval (10 and 11.7 μmol/L). One dog had timepoint 1 postprandial SBA above the reference interval at 20.1 μmol/L (reference interval 0-17 μmol/L). Repeat SBA 72 hours after UDCA discontinuation were normal. Long-term administration of UDCA to healthy dogs may increase fasting SBA above pretreatment values (typically within the reference interval). Long-term administration of UDCA to healthy dogs does not alter liver enzyme activities, and bilirubin, cholesterol, or triglyceride concentrations. © 2015 American Society for Veterinary Clinical Pathology.

Pesticide induced changes were assessed in thirty two subjects of attempted suicide cases. Among all, the farmers and their families were recorded as most frequently suicide attempting. The values obtained from seven biochemical variables of 29 years old (average age) hospitalized subjects were compared to the same number and age matched normal volunteers. The results revealed major differences in the mean values of the selected parameters. The mean difference calculate; alkaline phosphatase (178.7 mu/l), Bilirubin (7.5 mg/dl), GPT (59.2 mu/l) and glucose (38.6 mg/dl) were higher than the controls, which indicate the hepatotoxicity induced by the pesticides in suicide attempting individuals. Increase in serum creatinine and urea indicated renal malfunction that could be linked with pesticide induced nephrotoxicity among them. (author)

Full Text Available This study was undertaken to investigate the toxicological profile of a methanolic extract of Garcinia pedunculata fruit in rats by conducting hematological, biochemical, and histopathological examinations. Long Evans rats were divided into four groups, each with 6 animals, and were treated with three oral doses (250, 500, and 1000 mg/kg once daily for 21 days. The extract did not cause significant changes in body and relative organ weight, percent water content, or hematological parameters at any administered doses. However, a significant dose-dependent positive effect in serum lipid profile and all atherogenic indices including the cardiac risk ratio, Castelli’s risk index-2, and the atherogenic coefficient were observed. Significant increases in the levels of iron and decreases in serum alkaline phosphatase, alanine transaminase, and lactate dehydrogenase activities and the levels of serum glucose were noted when the extract was administered at the highest dose (1000 mg/kg. Histopathological examination of the target tissues further confirmed that the extract was safe and had no observed toxicological features. Our study indicates that G. pedunculata fruit is nontoxic, has the potential to be effective against atherosclerosis, and may be used as a hepatoprotectant. The fruit extract is also beneficial to those with iron deficiency and hyperglycemia.

Full Text Available It has been reported that higher folate intake from food and supplementation is associated with decreased blood pressure (BP. The association between serum folate concentration and BP has been examined in few studies. We aim to examine the association between serum folate and BP levels in a cohort of young Chinese women.We used the baseline data from a pre-conception cohort of women of childbearing age in Liuyang, China, for this study. Demographic data were collected by structured interview. Serum folate concentration was measured by immunoassay, and homocysteine, blood glucose, triglyceride and total cholesterol were measured through standardized clinical procedures. Multiple linear regression and principal component regression model were applied in the analysis.A total of 1,532 healthy normotensive non-pregnant women were included in the final analysis. The mean concentration of serum folate was 7.5 ± 5.4 nmol/L and 55% of the women presented with folate deficiency (< 6.8 nmol/L. Multiple linear regression and principal component regression showed that serum folate levels were inversely associated with systolic and diastolic BP, after adjusting for demographic, anthropometric, and biochemical factors.Serum folate is inversely associated with BP in non-pregnant women of childbearing age with high prevalence of folate deficiency.

Purpose: To observe bone loss and bone metabolism status in 5-year survivors after orthotopic liver transplantation (OLT). Methods: Measurement of bone mineral density (BMD) of the lumbar spine (L2∼L4) and femoral neck using dual energy X-ray absorptiometry (DEXA) and analysis of biochemical markers of bone turnover, such as ostecalcin (OSC), bone alkaline phosphatase (BAP), carboxy-terminal propeptide of type I procollagen (PICP), carboxy-terminal cross-linked telo-peptide of type I collagen (ICTP), PTH and 25-hydroxy-vitamin D (25-OH-D). These markers were measured in 31 5-year survivors after OLT, 34 patients with chronic liver failure (CLF) before OLT and 38 normal subjects. Results: Age-matched Z-score of BMD (Z-score) at L2∼L4 was significantly higher in 5-year survivors than that in patients with CLF before OLT. Incidence of osteoporosis (Z-score<-2.0) in 5-year survivors was significantly lower than that in patients with CLF before OLT. Although serum concentrations of bone formation and bone resorption markers in 5-year survivors were high than those of normal subjects, as compared to patients with CLF before OLT, serum OSC was increased, serum ICTP and BAP were reduced, serum PICP was unchanged. Serum PTH and 25-OH-D level was normal. Conclusions: In 5-year survivors following liver transplantation there was a reduction in bone loss and incidence of osteoporosis and an improvement of bone metabolism

On the Adaptive Design Rules of Biochemical Networks in Evolution

Bor-Sen Chen

2007-01-01

Full Text Available Biochemical networks are the backbones of physiological systems of organisms. Therefore, a biochemical network should be sufficiently robust (not sensitive to tolerate genetic mutations and environmental changes in the evolutionary process. In this study, based on the robustness and sensitivity criteria of biochemical networks, the adaptive design rules are developed for natural selection in the evolutionary process. This will provide insights into the robust adaptive mechanism of biochemical networks in the evolutionary process. We find that if a mutated biochemical network satisfies the robustness and sensitivity criteria of natural selection, there is a high probability for the biochemical network to prevail during natural selection in the evolutionary process. Since there are various mutated biochemical networks that can satisfy these criteria but have some differences in phenotype, the biochemical networks increase their diversities in the evolutionary process. The robustness of a biochemical network enables co-option so that new phenotypes can be generated in evolution. The proposed robust adaptive design rules of natural selection gain much insight into the evolutionary mechanism and provide a systematic robust biochemical circuit design method of biochemical networks for biotechnological and therapeutic purposes in the future.

18F-fluoride PET/CT exhibits high sensitivity to delineate and measure the extent of bone metastatic disease in patients with prostate cancer. 18F-fluoride PET/CT could potentially replace traditional bone scintigraphy in clinical routine and trials. However, more studies are needed to assess repeatability and biological uptake variation. The aim of this study was to perform test-retest analysis of quantitative PET-derived parameters and blood/serum bone turnover markers at the same time point. Ten patients with prostate cancer and verified bone metastases were prospectively included. All underwent two serial 18F-fluoride PET/CT at 1 h post-injection. Up to five dominant index lesions and whole-body 18F-fluoride skeletal tumour burden were recorded per patient. Lesion-based PET parameters were SUVmax, SUVmean and functional tumour volume applying a VOI with 50% threshold (FTV 50% ). The total skeletal tumour burden, total lesion 18F-fluoride (TLF), was calculated using a threshold of SUV of ≥15. Blood/serum biochemical bone turnover markers obtained at the time of each PET were PSA, ALP, S-osteocalcin, S-beta-CTx, 1CTP and BAP. A total of 47 index lesions and a range of 2-122 bone metastases per patient were evaluated. Median time between 18F-fluoride PET/CT was 7 days (range 6-8 days). Repeatability coefficients were for SUVmax 26%, SUVmean 24%, FTV 50% for index lesions 23% and total skeletal tumour burden (TLF) 35%. Biochemical bone marker repeatability coefficients were for PSA 19%, ALP 23%, S-osteocalcin 18%, S-beta-CTx 22%, 1CTP 18% and BAP 23%. Quantitative 18F-fluoride uptake and simultaneous biochemical bone markers measurements are reproducible for prostate cancer metastases and show similar magnitude in test-retest variation.

Empirical data on food web dynamics and predator-prey interactions underpin ecosystem models, which are increasingly used to support strategic management of marine resources. These data have traditionally derived from stomach content analysis, but new and complementary forms of ecological data are increasingly available from biochemical tracer techniques. Extensive opportunities exist to improve the empirical robustness of ecosystem models through the incorporation of biochemical tracer data and derived indices, an area that is rapidly expanding because of advances in analytical developments and sophisticated statistical techniques. Here, we explore the trophic information required by ecosystem model frameworks (species, individual, and size based) and match them to the most commonly used biochemical tracers (bulk tissue and compound-specific stable isotopes, fatty acids, and trace elements). Key quantitative parameters derived from biochemical tracers include estimates of diet composition, niche width, and trophic position. Biochemical tracers also provide powerful insight into the spatial and temporal variability of food web structure and the characterization of dominant basal and microbial food web groups. A major challenge in incorporating biochemical tracer data into ecosystem models is scale and data type mismatches, which can be overcome with greater knowledge exchange and numerical approaches that transform, integrate, and visualize data.

Petroselinum crispum, a bright green biennial shrub is widely used traditionally as a food additive and herbal remedies for many ailments. This study therefore aimed to assess the toxic effects of its leaf extract using some biochemical, haematological parameters. The toxic effects were assessed by quantifying liver enzymes such as serum aspartate amino transferase (AST), alanine amino transferase (ALT), alkaline phosphatase (ALP), total serum protein and liver weight. Effects on haematological parameters were assessed by analysis of parked cell volume (PCV), red blood cell count (RBC), white blood cells (WBC) and haemoglobin (Hb) concentrations. Histopathological studies were done on the liver and kidneys. The extract caused significant increase in serum activity of alanine amino transferase and blood urea nitrogen (BUN) levels at the dose of 1000 mg/kg. Other biochemical and haematological parameters were not affected at lower doses. Conversely, the liver weight was not affected after eight weeks of treatment at the dose levels studied. The organs obtained for pathological study, were structurally unchanged under histopathological evaluation at lower doses but inflammatory and necrotic features were observed at doses ≥ 1000 mg/kg. The results indicate that the leaf ethanol extract of Petroselinum crispum was hepatotoxic and nephrotoxic at continued oral doses equal to or more than 1000 mg/kg, but no obvious toxicity when used at lower doses. Therefore, there should be caution in its administration to avoid overdosing and known interaction with some medications. In addition, the plant should be kept away from pets and domestic animals and should not be cultivated on soil irrigated with waste water due to their ability to bio-accumulate toxic metals.

The leishmaniasis is a group of diseases caused by intracellular haemoflagellate protozoan parasites of the genus Leishmania. Leishmaniasis has diverse clinical manifestations; cutaneous leishmaniasis (CL) is the most common form of leishmaniasis which is responsible for 60% of disability-adjusted life years. CL is endemic in Yemen. In Shara'b there is no reference study available to identify the prevalence of endemic diseases and no investigation has been conducted for diagnosing the diseases. This study was conducted in villages for CL which collected randomly. The study aimed at investigating the epidemiological factors of CL in Shara'b by using questioner. Symptoms of lesions in patients suffering from CL, confirmed by laboratory tests, gave a new evidence of biochemical diagnosis in 525 villagers aged between 1 and 60 years old. Venous bloods were collected from 99 patients as well as from 51 control after an overnight fast. The percentage prevalence of CL was found 18.8%. The prevalence rate of infection among males (19.3%) was higher than females (18.40%). Younger age group (1-15) had a higher prevalence rate (20.3%) than the other age groups. Furthermore, the population with no formal education had the higher rate of infection (61% of the total). A significant increase of serum malondialdehyde (P < 0.001) in CL patients was obtained. The highest level of MDA may be due to over production of ROS and RNS results in oxidative stress and the acceleration of lipid peroxidation in CL patients. There were high prevalence rates of CL in Shara'b. The patient who had CL has been found with many changes in some biochemical levels. This study provides a clear indication on the role of MDA as an early biochemical marker of peroxidation damage occurring during CL. Increased uric acid, and catalase activity was provided of free radical.

Advances in technologies have brought us closer to routine spectroscopic diagnosis of early malignant disease. However, there is still a poor understanding of the carcinogenesis process. For example it is not known whether many cancers follow a logical sequence from dysplasia, to carcinoma in situ, to invasion. Biochemical tissue changes, triggered by genetic mutations, precede morphological and structural changes. These can be probed using Raman or FTIR microspectroscopy and the spectra analysed for biochemical constituents. Local microscopic distribution of various constituents can then be visualised. Raman mapping has been performed on a number of tissues including oesophagus, breast, bladder and prostate. The biochemical constituents have been calculated at each point using basis spectra and least squares analysis. The residual of the least squares fit indicates any unfit spectral components. The biochemical distribution will be compared with the defined histopathological boundaries. The distribution of nucleic acids, glycogen, actin, collagen I, III, IV, lipids and others appear to follow expected patterns.

Treatment options for patients with recurrent disease after radical prostatectomy include salvage radiotherapy of the prostatic bed and/or androgen deprivation therapy. To establish an effective treatment strategy for recurrent disease after radical prostatectomy, we retrospectively analyzed the outcome of salvage radiation monotherapy in such cases. Data from 61 men who had undergone salvage radiation monotherapy for biochemical recurrent disease after radical prostatectomy were retrospectively reviewed. In all patients, salvage radiotherapy consisted of iraradiation to the prostatic bed (70 Gy) using three-dimensional conformal radiotherapy techniques. Treatment outcome was analyzed to identify predictive factors of salvage radiotherapy. The biochemical recurrence-free survival after salvage radiation monotherapy at 2 and 5 years was 55% and 38%, respectively. Cox proportional regression models revealed that the independent predictive factors for biochemical recurrence were Gleason Score ≥ 8, negative surgical margin, and PSA velocity ≥ 0.38 ng/mL/year. Negative surgical margin and PSA velocity ≥ 0.8 ng/mL/year were significantly associated with poor response in the serum PSA levels after salvage radiotherapy. Based on our findings, we propose a treatment strategy for biochemical recurrent disease after radical prostatectomy. Patients with Gleason score ≤ 7, positive surgical margin, and PSA velocity < 0.38 ng/mL/year are categorized the most favorable group, so that eradication by salvage radiation monotherapy could be expected. Other patients could be divided to two groups depending on surgical margin status and PSA velocity: 1) patients who might require combination of SRT and short-term androgen deprivation therapy and 2) patients who should be treated by androgen deprivation monotherapy

Full Text Available Introduction: Ramadan is the ninth month of the lunar Islamic calendar, during which Muslims are obliged to perform specific rites and rituals. Fasting is considered the most important ritual during the holy month of Ramadan. Fasting variably influences the health of individuals, which could be attributed to the changes in the concentrations of certain biochemical markers. This study aimed to elucidate the health effects of fasting through evaluating the impact of this Islamic duty on blood biochemistry. Materials and Methods: This quasi-experimental study was conducted on 40 male volunteers employed at North Khorasan University of Medical Sciences, Iran.Data collection and phlebotomy were performed before fast breaking(Iftar on the first and last day of Ramadan. Fasting duration was 11 hours per day. Serum biochemical factors, including blood glucose, uric acid, albumin, low-density lipoprotein(LDL, high-density lipoprotein (HDL, total cholesterol and triglyceride(TG, were measured in all the participants at the beginning and end of Ramadan. Data analysis was performed in SPSS using paired-samples T-test to compare the mean variables. Results: Mean age of the participants in this study was 39.11±8.602 years. After one month of fasting, a significant reduction was observed in the mean levels of blood glucose, uric acid, TG, and LDL(P

To identify if there is a relationship between the deiodinase D2-Thr92Ala genetic variant, thyroid hormone levels and biochemical hypothyroidism in preeclampsia. We genotyped 125 women with preeclampsia and 131 normal pregnant women using PCR-RFLP. Serum thyroid hormone levels were determined using ELISA. Our study showed higher TSH and FT4 levels and lower FT3 levels in women with preeclampsia compared to normal pregnant women, with statistical significance for women with mild and severe preeclampsia. The risk to develop pregnancy-induced hypertension (PIH), mild or severe preeclampsia was increased in carriers of at least one D2-Ala92 allele. TSH and FT4 levels were significantly higher and FT3 levels were significantly lower in preeclamptic women with severe preeclampsia if they carried the D2-Ala92 allele compared to non-carriers. Pregnant women with PIH and mild preeclampsia, carriers of at least one D2-Ala92 allele, delivered at lower gestational age neonates with a lower birth weight compared to non-carriers, but the results were statistically significant only in severe preeclampsia. The D2-Thr92Ala genetic variant is associated with the severity and the obstetric outcome of preeclampsia, and it also influences thyroid hormone levels. The study demonstrates non-thyroidal biochemical hypothyroidism - as a result of deiodination effects due to D2 genotypes.

Three cDNAs encoding different phosphoglycerate kinase (PGK, EC 2.7.2.3) isoforms, two cytosolic (HacPGK1 and HacPGK2) and one plastidic (HapPGK), were cloned and characterized from developing sunflower (Helianthus annuus L.) seeds. The expression profiles of these genes showed differences in heterotrophic tissues, such as developing seeds and roots, where HacPGK1 was predominant, while HapPGK was highly expressed in photosynthetic tissues. The cDNAs were expressed in Escherichia coli, and the corresponding proteins purified to electrophoretic homogeneity, using immobilized metal ion affinity chromatography, and biochemically characterized. Despite the high level of identity between sequences, the HacPGK1 isoform showed strong differences in terms of specific activity, temperature stability and pH sensitivity in comparison to HacPGK2 and HapPGK. A polyclonal immune serum was raised against the purified HacPGK1 isoform, which showed cross-immunoreactivity with the other PGK isoforms. This serum allowed the localization of high expression levels of PGK isozymes in embryo tissues. Copyright © 2012 Elsevier Ltd. All rights reserved.

Simulation studies in biochemical signaling and enzyme reactions

Biochemical pathways characterize various biochemical reaction schemes that involve a set of species and the manner in which they are connected. Determination of schematics that represent these pathways is an important task in understanding metabolism and signal transduction. Examples of these Pathways are: DNA and protein synthesis, and production of several macro-molecules essential for cell survival. A sustained feedback mechanism arises in gene expression and production of mRNA that lead to protein synthesis if the protein so synthesized serves as a transcription factor and becomes a repressor of the gene expression. The cellular regulations are carried out through biochemical networks consisting of reactions and regulatory proteins. Systems biology is a relatively new area that attempts to describe the biochemical pathways analytically and develop reliable mathematical models for the pathways. A complete understanding of chemical reaction kinetics is prohibitively hard thanks to the nonlinear and highly complex mechanisms that regulate protein formation, but attempting to numerically solve some of the governing differential equations seems to offer significant insight about their biochemical picture. To validate these models, one can perform simple experiments in the lab. This paper introduces fundamental ideas in biochemical signaling and attempts to take first steps into the understanding of biochemical oscillations. Initially, the two-pool model of calcium is used to describe the dynamics behind the oscillations. Later we present some elementary results showing biochemical oscillations arising from solving differential equations of Elowitz and Leibler using MATLAB software.

A Novel Method for Pain Relief in Chronic Pancreatitis: an Old Drug in a New Pack: a Controlled Study.

Pujahari, Aswini Kumar

2017-12-01

Most of pain-relieving agents in chronic pancreatitis are nonspecific and unpredictable. Omeprazole induces hypergastrinemia due to reduced gastric acidity. Raised serum gastrin, in turn, modulates to reduce secretin level. Secretin is responsible for secretion of almost 80 % bicarbonate-rich pancreatic juice from the ductular epithelium without affecting enzyme output. It is a prospective randomized study in patients with CT-confirmed chronic pancreatitis. The control group got the standard care and 60 mg of omeprazole twice daily was added to the test group. Absence of pain relief at 14 days was considered as failure. Pain relief, weight gain and any toxic effect of omeprazole were reviewed at 12 months. One hundred thirty-seven cases were included, with an age range of 19 to 72 years. (mean 42.67). The majority of them were alcoholic males. At 2 weeks, pain relief was noted in 47/69(68.1 %) and 63/65(96.96 %) in the control and omeprazole group, respectively. At the end of 1 year, the omeprazole group had greater weight gain (95 %) than the control group (69.5 %). All the pseudocysts in the omeprazole group and most in the control group resolved. No side effect of omeprazole was seen. The high-dose omeprazole (HDO) group of patients had significantly better pain relief in chronic pancreatitis than those treated with conventional therapy. A high number of cases gained weight in the HDO group than the controlled group. No patient had clinical, endoscopic, biochemical, or haematological toxicity of HDO. More studies are necessary.

This study designed to evaluate the hazardous effects of gamma-radiation and to investigate the role of high protein diet, vitamin C and vitamin E as radioprotectors in rats followed exposure to a single dose of whole body gamma irradiation of 7 Gy. 120 male albino rats were divided into six equal groups of 20 rats each : control, irradiated , high protein (P), vitamin C, vitamin E and combination (C + E + P) supplemented groups. The variation in levels of total protein, albumin, globulin, A/G ratio, cholesterol, triglycerides, urea, creatinine, corticosterone, testosterone, apoptosis and the activities of ALT ,AST ,LDH ,CK and CKMB were estimated for all groups. Serum corticosterone and testosterone detection were carried out according to the radioimmunoassay (RIA) technique. Serum apoptosis detection was carried out using the Enzyme-linked immunosorbent assay (ELISA). Analyses were carried out at the end of one week pre gamma irradiation, one and two weeks post gamma irradiation . In the irradiated group, an increase in serum triglycerides, urea, creatinine and testosterone levels, apoptosis and ALT, AST, CK, LDH activities were observed compared to control. While there was a decrease in both globulin and cholesterol levels and no changes in albumin level and CKMB activity. In almost supplemented groups, the reverse was occurred except in triglycerides, cholesterol, globulin and CK . Based on these biochemical observations, it was concluded that vitamin C and vitamin E treatment exerts a protective effect against irradiation damage while high protein diet has protective or ameliorative effects to some extent

The quantification of long-chain fatty acids is fundamental for the diagnosis of several peroxisome disorders, particularly those in which the β-oxidation peroxisome of fatty acids is affected. In this work the implementation of an analytical method for the determination of these markers in serum by gas chromatography coupled to mass spectrometry is described. Besides, samples from patients with a diagnostic impression of adrenoleukodystrophy linked to the X chromosome were analyzed. The necessary experimental conditions were achieved for the separation and quantification of C22:0, C24:0 and C26:0 fatty acids in serum, which are biochemical markers of various peroxisome diseases. The application of this method allowed confirming the diagnosis of three patients with a diagnostic impression of adrenoleukodystrophy linked to the X chromosome. The application of the method in daily practice will allow the Cuban medical system to count on a new laboratory parameter for the diagnosis of peroxisome disorders

Cinnabar, an important traditional Chinese mineral medicine, has been widely used as a Chinese patent medicine ingredient for sedative therapy. However, the pharmaceutical and toxicological effects of cinnabar, especially in the whole organism, were subjected to few investigations. In this study, an NMR-based metabolomics approach has been applied to investigate the toxicological effects of cinnabar after intragastrical administration (dosed at 0.5, 2 and 5 g/kg body weight) on male Wistar rats. Liver and kidney histopathology examinations and serum clinical chemistry analyses were also performed. The 1 H NMR spectra were analyzed using multivariate pattern recognition techniques to show the time- and dose-dependent biochemical variations induced by cinnabar. The metabolic signature of urinalysis from cinnabar-treated animals exhibited an increase in the levels of creatinine, acetate, acetoacetate, taurine, hippurate and phenylacetylglycine, together with a decrease in the levels of trimethyl-N-oxide, dimethylglycine and Kreb's cycle intermediates (citrate, 2-oxoglutarate and succinate). The metabolomics analyses of serum showed elevated concentrations of ketone bodies (3-D-hydroxybutyrate and acetoacetate), branched-chain amino acids (valine, leucine and isoleucine), choline and creatine as well as decreased glucose, lipids and lipoproteins from cinnabar-treated animals. These findings indicated cinnabar induced disturbance in energy metabolism, amino acid metabolism and gut microflora environment as well as slight injury in liver and kidney, which might indirectly result from cinnabar induced oxidative stress. This work illustrated the high reliability of NMR-based metabolomic approach on the study of the biochemical effects induced by traditional Chinese medicine

Sixty six, 37-wk-old laying hens, of Lohmann strain, were used in the current study to evaluate the effects of dietary garlic powder (GP) on productive performance and certain biochemical aspects of laying hens. Hens were randomly allotted into 3 dietary treatment groups, a control (no garlic addition) and 3 and 6 % GP additions to the basal diet on weight: weight ratio basis and fed for six week. Body weights (BW), egg weight (EW) and feed consumption were determined weekly. Daily egg production was recorded. Serum concentrations of lipids profile ( triglycerides (Trig), total cholesterol (Chol), high density lipids (HDL) and low density lipids (LDL) cholesterol levels) and triiodothyronine (T3) concentration were measured. Results indicated that feed efficiency and BW gain were significantly increased as garlic powder percentage increased in the diet. Garlic powder supplementation at 3 and 6 % lower serum Chol concentrations on an average by 15.3 and 22.3%, respectively, as compared to the control group. Serum Trig concentration was significantly lower by 18 and 33% respectively as compared to the control group. TLs were highly significantly decreased as the garlic powder increase by 13.9 and 27.8% respectively, and as compared to the control group. Moreover, HDL-cholesterol was significantly increased and LDL- cholesterol was significantly decreased with garlic powder increased in the diet. Serum T3 concentration was significantly higher on average by 23.2 and 28.4%, in laying hens given the 3 and 6 % garlic powder supplementation as compared to the control group. It could be concluded from the results of the current study that supplementing the diet with 3 and to a greater extent with 6 % of garlic powder decreases the major risk factors for the development and progression of atherosclerosis and coronary artery disease by lowing concentrations of serum total cholesterol, triglycerides concentrations, and HDL cholesterol, and increasing levels of HDL

A study was undertaken in five draught horses of 648 +/- 33 kg body weight to find the effects of continuously pulling loads on their cardiovascular, respiratory and metabolic responses. A cart equipped with an odometer, for measuring distance, and a hydraulic dynamometer, for measuring draught force, was used. Heart and respiration rates and rectal temperatures were recorded. Blood samples for measuring arterial and venous pH and blood gases, haemoglobin, glucose and lactic acid concentrations and the serum activity of the enzymes creatine phosphokinase (CK), lactate dehydrogenase, aspartate aminotransferase and alkaline phosphatase were taken before exercise and immediately after each journey (morning and afternoon) of the daily work. Draught exercise, with loads which generated forces of between 0.57 and 0.59 kN, at speeds of 1.60 to 2.11 m/s, for 8 h daily for five consecutive days, with resting intervals of 10 min each hour, was well tolerated. Exercise tolerance was evaluated from the recovery from the changes observed in the biochemical and physiological parameters induced by the work. The analysis of these showed that, when the horses were subjected to prolonged periods of resting, their loss of fitness for work was shown by significant increases in the serum activity of muscle-derived enzymes and in blood lactate concentrations during the first day of work. However, over the following days the horses adapted to the work, so that the decreases in serum enzyme activities and blood lactate concentrations were reduced. Since similar observations have been described for racehorses, the determination of blood lactate concentrations and the serum activities of muscle-derived enzymes, specifically CK, seem to be good indicators of fitness in draught horses.

Many changes happen during growth and development in an organism as a result of important hormon changes, especially biohumoral ones. These changes make a problem when interpreting biochemical results in pediatric population. The most important changes are intensive calcium and phosphorus metabolic turnover in bone tissue with changes in alkaline phosphatase activity as a result of osteoblast activity. The aim of this study was to follow the serum calcium and phosphorus concentration and alkaline phosphatase activity in children 1-15 years old in different growth and development period and of different sexes and to fortify the influence of growth and development dynamics on biohumoral status in healthy male and female children. We evaluated 117 healthy children of both sexes from 1-15 years of age and divided them into three age groups: 1-5, 6-10 and 11-15 years. We followed the serum calcium and phosphorus concentration and alkaline phosphatase activity in different groups and in different sexes. Our investigation found significantly higher values of serum calcium in boys than in girls with no important changes between the age groups and significantly higher values of serum phosphorus in the youngest age group in all children and in different sexes with no important sex differences. Alkaline phosphatase activity followed the growth spurt and was the biggest in 6-10 years group in girls and in 11-15 years group in boys.

Objective: To study the correlation between serum level of PC III and the degree of liver fibrosis in patients with chronic liver diseases. Methods: Serum level of PC III was assayed with RIA and other markers of liver function (including ALT, AST, STB, SDB, TP, ALB, TBA) were assayed with automatic biochemical analyzer in 188 patients with various chronic liver diseases. PC III only were examined in 70 controls. Results: (1) The serum levels of PC III were in this order: chronic severe hepatitis (n=27, 501.17 ± 191.09) > liver cirrhosis from chronic hepatitis (n=27,334.52 ± 139.14) > chronic moderate hepatitis ( n = 32,298.02 ± 151.02) > primary liver cancer (n=39,281.42 ± 143.48) > normal controls (n=70,122.56 ± 92.94). (2) The serum levels of PC III were positively correlated with STB and SDB levels (P<0.05) in patients with chronic severe hepatitis and was significantly positively correlated with ALP levels (P<0.01). (3) The serum level of PC III were significantly positively correlated with STB, SDB, TBA and ALP in patients with cirrhosis from chronic hepatitis (P<0.01). (4) The serum levels of PC III were significantly positively correlated with AST and ALP levels in patients with chronic moderate hepatitis (P<0.01). (5) The serum levels of PC III were significantly positively correlated with STB, SDB, TBA, AST and ALP in patients with primary liver cancer (P<0.01). Conclusion: Serum level of PC III might adequately reflect the activity of the process of hepatic fibrosis, but did not necessarily reflect the degree of fibrosis already attained. (authors)

Biopsy liver specimens from healthy control subjects (N=5) and patients with various liver diseases (N=43) were investigated by the vitro autoradiography. The Leevy technique of adding /sup 3/H-5-uridine (/sup 3/H-U) to the incubation medium was used. In healthy subjects labeling with /sup 3/H-U was observed mostly in hepatocytes and Kupffer cells and the frequency of /sup 3/H-U labeled cells was extremely high. Higher frequencies of labeled fibrocytes and endothelial cells of the blood vessel were found in acute hepatitis than in control subjects. In the active form of chronic hepatitis, significantly higher counts of labeled fibrocytes, ductular cells and lymphocytes were found. In patients with acute hepatitis or the inactive form of chronic hepatitis, only a few labeled lymphocytes were observed. Larger numbers of labeled fibrocytes were found in patients with chronic hepatitis with sublobular hepatic necrosis, than in patients with the active form of chronic hepatitis. In cirrhotic livers, marked increases of labeled ductular cells, fibrocytes and bile duct cells were found. No significant labeling differences were observed in the hepatocytes of various liver diseases. In chronic hepatitis with sublobular hepatic necrosis, a more significant decrease of labeled Kupffer cells was present than in the inactive form of chronic hepatitis. Labeled ductular cells and fibrocytes increased as the disease progressed from acute hepatitis to liver cirrhosis. The labeling index of rosettes cells was intermediate between the hepatocytes and ductular cells. The ratio of labeled parenchymal to non-parenchymal cells decreased proportionally from chronic hepatitis to cirrhosis.

Background: Hyperuricemia can cause serious health problems including renal insufficiency. Hyperuricemia is associated with many diseases including Hypertension, Diabetes Mellitus, Hypertriglyceridemia and Obesity. Objective of the present study was to study the Association of Serum Uric Acid with Blood Urea and Serum Creatinine. Methods: Eighty subjects, aged above 40, having blood urea more than 40 mg/dl and serum Creatinine more than 1.3 mg/dl were selected. 52.5 % subjects were male. Eighty subjects were selected as control group matching the age and sex with study group with normal blood urea and serum Creatinine. Results: Serum Uric Acid was found to be raised in 33 patients. Mean Serum Uric Acid value was 6.98+-2.021 in males (p<0.05) and 5.054+-2.324 in females (p<0.05). Conclusion: Serum Uric Acid is raised in patients with impaired renal function (p<0.05). Levels of increased Serum Uric Acid were not significantly associated with the cause of renal disease. (author)

Objective: To evaluate the biochemical changes associated with succinylcholine administration after pretreatment with rocuronium at different time intervals. Method: The prospective, randomised, single-blinded study was conducted at the Combined Military Hospital, Rawalpindi, from January to May 2010. Ninety male, aged 18-60 years, American Society of Anaesthesiology I or II patients undergoing elective inguinal herniotomy or external haemorrhoidectomy were included. The patients were randomly divided into three equal groups. Group A received a normal saline 5ml as placebo 1 minute before succinylcholine; Group B received rocuronium 0.06 mg/kg 1 intravenously minute before succinylcholine, while Group C received intravenous injection of rocuronium 0.06 mg/kg 5 minute before succinylcholine. Venous blood samples for creatinine phosphokinase, lactate dehydrogenase and myoglobin plasma concentrations were obtained at 0, 30 minutes, 6 hours and 24 hours after succinylcholine administration. Results: Mean serum creatinine phosphokinase and myoglobin concentrations were significantly decreased in Groups B and C compared to Group A at 30 minutes and 24 hours (p<0.05). However, no significant difference in the enzyme levels at any time interval was observed among the rocuronium groups. There was a significant rise in lactate dehydrogenase concentrations at 6 hours and 24 hours in Group A compared to Groups B and C (p<0.05). Conclusion: Pretreatment with rocuronium effectively reduces the biochemical changes associated with succinylcholine-induced muscle fasciculations. However, whether it is given 1 minute or 5 minutes before succinylcholine does not make much difference. (author)

Fifteen percent of patients who later have hemolysis, elevated liver enzymes, and low platelets syndrome develop initially have nonspecific symptoms. Early diagnosis could ensure adequate obstetric management; however, prognostic biochemical tests are lacking. We hypothesized that elevated hyaluronic acid serum levels might be an early indicator of hemolysis, elevated liver enzymes, and low platelets syndrome because it is known to be a sensitive marker of liver cell function. Hyaluronic acid in serum was measured in patients with normal pregnancies (n = 109) and in those patients with pregnancies complicated by preeclampsia (n = 14) or hemolysis, elevated liver enzymes, and low platelets syndrome (n = 11). A significant increase in hyaluronic acid serum concentrations was observed in patients with hemolysis, elevated liver enzymes, and low platelets syndrome or with preeclampsia (p hyaluronic acid serum levels in hemolysis, elevated liver enzymes, and low platelets syndrome correlated with the clinical severity of the individual course of disease as measured by intensive care unit time (r = 0.72; p hyaluronic acid in preeclampsia and hemolysis, elevated liver enzymes, and low platelets syndrome are significantly elevated and might play an important diagnostic and prognostic role in patients with hemolysis, elevated liver enzymes, and low platelets syndrome.

The aim of the present study was to evaluate the cerebrospinal fluid (CSF)/serum leptin ratio during pharmacological therapy for obesity with centrally and peripherally acting drugs. Thirty-one obese women (mean age, 32.3 +/- 10 yr; body mass index, 38.2 +/- 5.2 kg/m(2); body fat, 43.3 +/- 5.4%) were studied before and 2 months after a weight loss program consisting of a balanced diet (1200 kcal/d) plus drug therapy. The patients were randomly assigned into three study groups: group I, fenproporex 25 mg/d (n = 10); group II, sibutramine 10 mg/d (n = 10); and group III, orlistat 120 mg tid (n = 11). Body fat, measured by dual-energy x-ray absorptiometry, and serum and CSF concentrations of leptin were examined at baseline and 2 months after therapy. At baseline, clinical and biochemical characteristics of the groups were similar. All of the women lost weight, approximately 7.0% of their initial body weight, and the reduction was not different among the groups. Serum leptin fell significantly after 2 months in all groups, and the decline was proportional to the reduction in body fat, because leptin levels adjusted for body fat did not change after treatment. CSF leptin levels showed a significant decrease after 2 months in all groups, and this decline was higher on group III compared with group I (P = 0.006). After therapy, the CSF/serum leptin ratio did not change in group I (1.57 +/- 0.3 to 1.72 +/- 0.62%) and group II (1.78 +/- 1.01 to 1.69 +/- 1.27%), whereas it declined significantly in group III (1.65 +/- 0.43 to 1.09 +/- 0.47%; P obese women treated during 2 months with orlistat, whereas this ratio did not change in this period of time in obese women treated with fenproporex and sibutramine.

Full Text Available Aim: To determine the effect of the use of folic acid supplementation on serum folate levels in Turkish pregnant women. Material and Method: Clinical records of a total of 397 patients were retrospectively examined. The patients were recruited into 2 groups based on folic acid supplementation. Group 1 included 294 women who did not take any folic acid tablets before or during pregnancy and Group 2 consisted of 103 women who regularly took 400 mcg of folic acid daily, starting from the preconception period. Both groups were compared with respect to demographic and biochemical characteristics. Results: The patients in Group 1 and 2 had statistically similar pre-pregnancy and pregnancy hemoglobin, pre-pregnancy and pregnancy serum calcium, and pre-pregnancy and pregnancy serum folate concentrations (p=0.544, p=0.549, p=0.289, p=0.299, p=0.072, and p=0.061 respectively. No statistically significant difference was determined between pre-pregnancy and pregnancy folate concentrations in Group 1 (p=0.059. Pre-pregnancy and pregnancy folate concentrations were statistically similar in Group 2 (p=0.057. Both study groups were determined as statistically similar with respect to perinatal outcomes, including molar pregnancy, intrauterine demise, neural tube defects, ventricular septal defect, fetal growth restriction, preeclampsia, preterm birth, birth weight, neonatal intensive care unit admission, and 1st minute and 5th minute Apgar scores (p=0.760, p=0.576, p=0.382, p=0.553, p=0.452, p=0.940, p=0.683, p=0.855, p=0.710, p=0.910, and p=0.924 respectively. Discussion: Based on the findings of the present study, it may be considered that serum folate concentrations in pregnant women can be maintained by dietary intake alone of over 4.5 ng/ml.

An influence of various humic-plant feed additives based on some herbs (nettle, chamomile, yarrow, perforatum), lucerne and humic materials on biochemical indices of Lohmann Brown (LB) layers blood plasma was estimated. Hens were housed in deep litter system, 20 birds in a group. Four groups were formed: control (C - standard feeding), and experimental, supplemented with prepara- tions: E-1 herbal-humic, E-2 humic-herbal and E-3--humic-lucerne. Hens were placed in the pens on the 16th week of life, addition of preparations with standard food mixture started at the 22nd wk and lasted until 66th wk of life. Blood for analyses was collected four times in the following periods: 27, 37, 54 and 65th wk of life. The applied humic-plant preparations to a limited degree affected the values of examined biochemical parameters in serum: total protein (TP), albumins (Albs), glucose (Glu), urea, triacylglycerols (TAG), total cholesterol (TCh), alanine aminotransferase (ALT), aspartate aminot- ransferase (AST) and alkaline phosphatase (ALP). It is difficult to determine based on these study, which preparation is one the most active biologically, however is seems that humic-lucerne prepara- tion affected the examined blood parameters to the highest degree. The reference values ranges in hens blood serum LB hens were proposed for: TP (43-65 g/l), Albs (15-22 g/l), urea (0.5-1.2 mmol/l), Glu 10-15 mmol/l), TCh (2.2-4.5 mmol/l), TAG (10-24 mmol/l), AST (4-12 U/l), ALT (150-280 mmol/l) and ALP (190-350 U/l).

We examined the relationships between pre-pregnancy maternal body mass index (BMI), pregnancy outcomes and biochemical markers. This study was conducted as a cross-sectional analysis. Korean women in their second and third trimesters of pregnancy were recruited at two hospitals in the metropolitan Seoul area. Pre-pregnancy BMI was categorized in four groups according to the Asia-Pacific standard. Fasting blood samples were obtained and analyzed for serum levels of homocysteine, folate and high-sensitivity C-reactive protein (hs-CRP). Concentrations of fetal fibronectin were assessed in the cervix and vagina, and cervical length was measured. Obese subjects had a lower education level and a lower income level than subjects of normal weight. The level of maternal stress was positively associated with pre-pregnancy BMI. Normal weight subjects were more likely to eat breakfast and consume meals of appropriate size than the rest of our sample. In overweight and obese subjects, weight gain during pregnancy was significantly lower than in the underweight and normal subjects. High pre-pregnancy maternal BMI increased the risks of preterm delivery (odds ratio (OR)=2.85, confidence interval (CI)=1.20-6.74), low-birth-weight (LBW) infants (overweight subjects: OR=5.07, CI=1.76-14.63; obese subjects: OR=4.49, CI=1.54-13.13) and macrosomia. In obese subjects, the average serum folate level was significantly lower than in the underweight subjects. In obese subjects, the average serum hs-CRP level was significantly higher than in the rest of our sample. Pregnancy outcomes are influenced by pre-pregnancy BMI. These findings suggest that women can minimize their risks of preterm delivery, LBW and macrosomia by maintaining normal pre-pregnancy BMI.

Full Text Available Serum cystatin C (CysC has been identified as a possible potential biomarker in a variety of diabetic complications, including diabetic peripheral neuropathy and peripheral artery disease. We aimed to examine the association between CysC and diabetic foot ulceration (DFU in patients with type 2 diabetes (T2D. 411 patients with T2D were enrolled in this cross-sectional study at a university hospital. Clinical manifestations and biochemical parameters were compared between DFU group and non-DFU group. The association between serum CysC and DFU was explored by binary logistic regression analysis. The cut point of CysC for DFU was also evaluated by receiver operating characteristic (ROC curve. The prevalence of coronary artery disease, diabetic nephropathy (DN, and DFU dramatically increased with CysC (P<0.01 in CysC quartiles. Multivariate logistic regression analysis indicated that the significant risk factors for DFU were serum CysC, coronary artery disease, hypertension, insulin use, the differences between supine and sitting TcPO2, and hypertension. ROC curve analysis revealed that the cut point of CysC for DFU was 0.735 mg/L. Serum CysC levels correlated with DFU and severity of tissue loss. Our study results indicated that serum CysC was associated with a high prevalence of DFU in Chinese T2D subjects.

Full Text Available To determine the clinicopathological risk factors and reliable biochemical predictors of the development of hypocalcemic symptoms after total thyroidectomy on the basis of serum calcium and intact parathyroid hormone (PTH levels measured 1 hour after surgery, a prospective study was performed on 817 patients who underwent a total thyroidectomy with central compartment node dissection (CCND due to well-differentiated thyroid cancer. We evaluated the correlations between hypocalcemic symptom development and clinicopathological factors. And the predictability for hypocalcemic symptom development of intact PTH cut-offs (<10 pg/mL and <20 pg/mL, resp. according to serum calcium level subgroup was analyzed. Female gender (P<0.001 was the only independent risk factor for hypocalcemic symptom development in multivariate regression analysis. The negative predictive value (NPV of intact PTH, signifying nondevelopment of hypocalcemic symptoms, was higher than the positive predictive value (PPV which signified development of hypocalcemic symptoms. In addition, when we applied the different adoption of the intact PTH cut-off according to serum calcium level, we could obtain more increased NPVs. A female gender and the application of more specific cut-offs for intact PTH according to the serum calcium levels measured 1 hour after surgery may help the patients to be more safely discharged.

Previous studies have shown that rifampicin induced choleresis, the mechanisms of which have not been described. The aim of this study was to investigate the mechanisms underlying in vivo rifampicin-induced choleresis. In one experimental set, rats were treated chronically with rifampicin on days 1, 3 and 7. Serum and biliary parameters were assayed, and mRNA and protein levels, as well as the locations of the hepatic export transporters were analyzed by real-time PCR, western blot and immunofluorescence. Ductular mass was evaluated immunohistochemically. In another experimental set, rats received an acute infusion of rifampicin. The amount of rifampicin in bile was detected using HPLC. Biliary parameters were monitored following intrabiliary retrograde fluxes of the Cl(-)/HCO3 (-) exchange inhibitor 4,4'-diisothiocyanatostilbene-2,2'-disulfonic acid (DIDS) or 5-nitro-2-(3-phenylpropylamino)benzoic acid (NPPB) in the infused rats. Biliary bicarbonate output increased in parallel to the augmented bile flow in response to rifampicin, and this effect was abolished with intrabiliary administration of DIDS, but not NPPB. The biliary secretion of rifampicin with increases in bile flow and biliary rifampicin in response to different infused doses of the antibiotic show no significant correlations. After rifampicin treatment, the expression level of anion exchanger 2 (AE2) increased, while the location of hepatic transporters did not change. However, RIF treatment did not increase ductular mass significantly. These results indicate that the increase in bile flow induced by rifampicin is mainly due to increased HCO3 (-) excretion mediated by increased AE2 protein expression and activity.

Full Text Available The grass snake Natrix natrix (Linnaeus, 1758 is a partly hygrophilous species, distributed throughoutUkraine. This snake may be considered as a test object for environmental biomonitoring. Modern biochemical methods make it possible to obtain new scientific data on the effects of anthropogenic pressure on reptiles. Blood is a sensitive and informative indicator of the condition of an organism as it responds quickly to most changes in exogenous and endogenous factors, and reflects negative influences on both individual and, indirectly, populations. Changes in biochemical parameters may be used as biomarkers of the state of health of reptiles in ecosystems under varying degrees of anthropogenic pressure. Due the increase in anthropogenic influence the development and introduction of new methods of perceptual research, collection of up-to-date information and development of a database of reptile biochemical parameters have become an urgent priority. We collected mature individuals of the grass snake in floodplain ecosystems on the right bank of the Dnieper River in Dnipropetrovsk city. Grass snakes from floodplain habitats on the left bank of theSamaraRiver (O.L. Belgard Prysamarskii International Biosphere Station, Novomoskovsk district, Dnipropetrovsk province were studied as the control specimens. Our study demonstrated statistically significant differences between snakes from the study sites in the amount of albumin, urea and urea nitrogen, and inorganic phosphorus, as well as in alanine aminotransferase (ALT and alkaline phosphatise (AP activity. The amount of albumin in the blood serum of specimens from the anthropogenically transformed areas was significantly lower (by 25% than in that of the snakes caught in the control habitats. Decrease of the albumin concentration usually indicates abnormal processes in the kidneys and liver. According to the changes observed in the concentration of albumin, a corresponding increase in the albumin to

In recent years it was verified there are an alarming growing number of teenagers and young adults using a combination of dietary supplements (DS) anabolic androgenic steroids (AAS) and drugs of abuse. This practice is used to improve physical fitness and appearance, may cause serious side effects. This article shows the alterations in the hematological and renal function parameters associate with these substances in 40 athletes. This research involved three steps: 1-the administration of a self-completion questionnaire ; 2-the assessment of hematological and biochemical parameters of renal function and; 3-toxicological urinalysis. Hematological and biochemical tests were conducted in an accredited laboratory and the toxicological urinalysis was validated in our laboratory using liquid-liquid extraction (LLE) and gas chromatography-mass spectrometry (GC-MS). The testosterone levels in the participants who consumed steroids increased 20-60% and alterations in serum creatinine, urea and uric reached values of up to 1.9; 60.6 and 7.5mg/dL, respectively. The toxicological urinalysis supports self-reports confirming the use of AAS and recreational drugs, putting at risk the health of those athletes increasing the chances of kidney diseases.

2012-06-01

Full Text Available Fetuin-A is a calcification inhibitor, negative acute phase response marker and cardiovascular mortality predictor in hemodialysis patients. Low levels of fetuin-A are associated with malnutrition, inflammation, decreased bone mass density, low-turnover bone and use of high calcium concentration dialysate. Hemodialysis procedure (HD has been shown to decrease fetuin-A levels by 20%, probably due to HD-induced inflammation or acute changes in calcium metabolism. The aim of our study was to investigate effects of HD on serum fetuin-A levels. Forty clinically and hemodynamically stable hemodialysis patients (21 females, 68 (38-85 years underwent routine bicarbonate hemodialysis or hemodiafiltration with polysulfone dialyzer. On consecutive HD dialysis solution with different calcium concentration with/without citric acid was used to assess influence of calcium shifts and parathyroid activity on fetuin-A changes during HD. All other parameters of HD were kept constant. Serum fetuin-A, calcium, phosphorus, iPTH, CRP and other biochemical parameters were measured before and after each HD. Our data show that predialysis serum fetuin-A levels have positive correlation with iPTH levels (p<0.05 and tendency to decrease with higher CRP levels. There was no change in fetuin-A levels during HD: 206 (167.1; 231.9 ug/ml before and 208.9 (170.3; 246.3 ug/ml after HD; respectively. When corrected for haemoconcentration, decrease in fetuin-A was only 2.8% (p<0.05. There was also no difference between effect of hemodialysis and hemodia-filtration procedure. The use of different calcium dialysate concentrations had distinct effect on iPTH levels during and after HD, however, we observed no associated changes in fetuin-A levels. The use of dialysate solution with citric acid had no effect on fetuin-A levels. In conclusion, standard bicarbonate HD with polysulfone dialyser and ultrapure dialysate induces only minor changes in fetuin-A and no changes in hsCRP levels

Full Text Available As there is effective intervention for delaying or preventing metabolic diseases, which are often present for years before becoming clinically apparent, novel biomarkers that would mark metabolic complications before the onset of metabolic disease should be identified. We investigated the role of fasting serum amino acids and their associations with inflammatory markers, adipokines, and metabolic syndrome (MetS components in subjects prior to the onset of insulin resistance (IR. Anthropometric measurements, food records, adipokines, biochemical markers, and serum levels of amino acids were determined in 96 asymptomatic subjects aged 25–49 years divided into three groups according to the number of MetS components present. Cysteine and tyrosine were significantly higher already in group with one component of MetS present compared to subjects without MetS components. Serum amino acid levels correlated with markers of inflammation and adipokines. Alanine and glycine explained 10% of insulin resistance variability. The role of tyrosine and cysteine, that were higher already with 1 component of MetS present, should be further investigated as they might point to future insulin disturbances.

This study was conducted to investigate the effect of low level doses of fission neutrons from Cf 252 source on sublethal doses (low medium) of snake venom cerastes cerastes by injecting albino eats with unirradiated or irradiated venom and measuring the biophysical alterations in the blood serum of the rats. The biophysical properties of the total serum proteins were studied through measuring their dielectric relaxation and the electric conductivity in the frequency range 0.1→5 MHz at 4 degree C. The absorption spectra of the extracted total serum protein were also measured. The results indicated that there are pronounced changes in the molecular constructions of the total serum protein such as the molecular radii, shape, the relaxation time and dielectric increment for the rats injected with unirradiated venom but for the rats injected with irradiated venom (3x10 8 n/cm 2 ) corresponding values approach the control value. These changes in the molecular constructions of the total serum protein indicate changes in its biochemical properties. This fact was revealed in a previous work, where the irradiation with the fast neutrons were found to decrease the toxicity of the venom

Aim: The study was designed to evaluate the hemato-biochemical alterations, urinalysis along with histomorphological and histological changes of prostate glands in dogs affected with benign prostatic hyperplasia (BPH) in and around Bhubaneswar, Odisha, India. Materials and Methods: In toto, 445 dogs presented to the Teaching Veterinary Clinical Complex of the College of Veterinary Sciences and Animal Husbandry, one Government Veterinary Hospital and two pet clinics in and around Bhubaneswar screened for the presence of BPH. Most of the 57 dogs were 6 years and above as reported by the owners. Only 57 dogs found positive for BPH basing on the presence of typical clinical signs subjected for a detailed hemato-biochemical study. Most of the 57 dogs were 6 years and above as reported by the owners. Routine and microscopic urinalyses were done as per the routine procedure. Histomorphological evaluations of prostate glands were done through manual rectal palpation. Histological examinations of prostate tissue sections of two dead dogs were conducted with routine hematoxylin and eosin stain. Results: The study revealed about 12.8% (57/445) of dogs was suffering from BPH. Typical clinical signs - such as passing small thin tape-shaped feces, holding tail away from backward, tenesmus, and straining during urination and defecation - were seen in most of the cases. Urine samples of affected dogs were positive for glucose, occult blood, and protein. A significant decrease in lymphocytes and increase in eosinophil counts in dogs with BPH was recorded. Serum biochemical analysis showed a nonsignificant increase in creatinine and blood urea nitrogen with a significant decrease in total protein, albumin, globulin, A:G ratio. Histology of prostate glands collected during postmortem was characterized by fibrosis of prostate gland, and hyperplasia of the acinar epithelium. Conclusions: High rate of the prevalence of BPH in dogs poses an alarming condition which if diagnosed at an

Serum sex hormone and growth arrest-specific protein 6 levels in male patients with coronary heart disease

Full Text Available Epidemiological studies have shown a high prevalence of low serum testosterone levels in men with cardiovascular disease. Moreover, the tyrosine kinase receptor Axl, the ligand of which is growth arrest-specific protein 6 (GAS6, is expressed in the vasculature, and serum GAS6 levels are associated with endothelial dysfunction and cardiovascular events. Testosterone regulates GAS6 gene transcription directly, which inhibits calcification of vascular smooth muscle cells and provides a mechanistic insight into the cardioprotective action of androgens. This study was designed to determine the correlation between serum GAS6 and testosterone levels in male patients with coronary heart disease (CHD. We recruited 225 patients with CHD and 102 apparently healthy controls. Serum concentrations of GAS6 and soluble Axl were quantified by an enzyme-linked immunosorbent assay. Levels of high-sensitivity C-reactive protein, testosterone, estradiol, and other routine biochemical markers were also measured. Testosterone decreased from 432.69 ± 14.40 to 300.76 ± 6.23 ng dl−1 (P < 0.001 and GAS6 decreased from 16.20 ± 0.31 to 12.51 ± 0.19 ng ml−1 (P < 0.001 in patients with CHD, compared with control subjects. Multiple linear regression analysis showed that serum testosterone and GAS6 levels were positively associated in male patients with CHD. Alterations in GAS6 levels may influence the development of CHD. Downregulation of GAS6/Axl signaling in the presence of low sex hormone levels during disease progression is a potential mechanism by which GAS6 affects CHD. This study provides novel results regarding the influence of sex hormones on serum GAS6 levels in patients with CHD.

Full Text Available Objectives. Aluminium, a neurotoxic agent in humans, has been implicated in the pathogenesis of neurodegenerative disorders. In this study, we examined the behavioral and biochemical effects of aluminium in rats with special emphasis on memory centres, namely, hippocampus and frontal cortex. Further, the effect of simvastatin treatment on aluminium intoxication was evaluated. Methods. Rats were exposed to aluminium chloride (AlCl3 for 60 days. Simvastatin (10 mg/kg/p.o. and rivastigmine (1 mg/kg/p.o. were administered daily prior to AlCl3. Behavioral parameters were assessed using Morris water maze test and actophotometer followed by biochemical investigations, namely, acetylcholinesterase (AChE activity, TNF-α level, antioxidant enzymes (GSH, catalase, lipid peroxidation, and nitrite level in hippocampus and frontal cortex. Triglycerides, total cholesterol, LDL, and HDL levels in serum were also determined. Key Findings. Simvastatin treatment improved cognitive function and locomotor activity in rats. Simvastatin reversed hyperlipidemia and significantly rectified the deleterious effect of AlCl3 on AChE activity. Further, in hippocampus and frontal cortex, aluminium-induced elevation in nitrite and TNF-α and reduction in antioxidant enzymes were inhibited by simvastatin. Conclusion. To conclude, the present study suggests that simvastatin per se protects the neurons in hippocampus and frontal cortex from AlCl3, an environmental toxin.

Muscle sufficiency was significantly lower in 1336 children with chronic malnutrition of moderate to severe degree. 18 children with a chronic moderate degree of malnutrition and 8 well-nourished age-matched controls were selected for biochemical and 31-phosphorus magnetic resonance spectroscopy (31-P MRS) studies. The results shows that: (a) serum total protein, albumin, iron, calcium and inorganic phosphate were similar in both groups; (b) serum enzyme levels were significantly increased in the malnuourished group; (c) 31-P MRS showed significantly higher means for total ATP, [beta]-ATP, [alpha]-ATP and inorganic phosphate for the malnourished compared to the control group. In chronic malnutrition, proteins are maintained by degradation in muscle resulting in release of amino acids and enzymes. 31-P MRS studies showing increases in total ATP, [beta]-ATP and inorganic phosphate and a decrease in phosphocreatine suggest that ATP is maintained at the cost of phosphocreatine. 22 refs., 4 tabs. 1 fig.

Full Text Available Oxidized LDL (ox-LDL lipoproteins are proposed as important modified particles triggering pro-inflammatory events through receptor-mediated pathways. We evaluated the circulating ox-LDL level on the concept that the chronic immune events may affect ox-LDL clearance as the vessel stenosis develops in coronary arteries. One hundred sixty five subjects underwent coronary angiography and then, subdivided into four subgroups controls (n=85; SVD, 2VD and 3VD (n=80. The serum ox-LDL level and other biochemical parameters were measured using ELISA method and routine laboratory techniques, respectively. The serum ox-LDL level in the control group (4.81±1.41 mU/mg was significantly higher than patients (4.28±1.73 mU/mg, P<0.05. The ox-LDL/LDL ratio was conversely reduced with the extent of stenosis as compared with the controls (P<0.05. Furthermore, no difference was observed in the ox-LDL/LDL ratio between the 2VD and 3VD patients. We suggested the atherosclerosis process increases the total clearing capacities of the circulating ox-LDL particles.

The potential value of a biobank depends on the quality of the samples, i.e. how well they reflect the biological or biochemical state of the donors at the time of sampling. Documentation of sample quality has become a particularly important issue for researchers and users of biobank studies. The aim of this study was to investigate the long-term stability of selected components: cholesterol, high density cholesterol (HDLC), low density cholesterol (LDLC), apolipoprotein A1 (apo-A1), apolipoprotein B (apo B), follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), thyroid stimulating hormone (TSH) and free thyroxin (FT4). Samples, stored at -25°C, from 520 men aged 40-49 years at blood sampling distributed in equally sized groups (n=130) according to length of storage, 0, 4, 17 and 29 years, respectively, were used in a cross sectional design. The freshly collected serum samples were used as a reference group to calculate storage related changes. The differences between fresh samples and samples stored for 29 years were substantial for apo-A1 (+12%), apo-B (+22.3%), HDLC (-69.2%), LDLC (+31.3%), and PRL (-33.5%), while total cholesterol, FSH, LH, TSH and FT4 did not show any significant difference. The study showed large differences in serum level of the selected components. The lipids and apolipoproteins were all changed except for total cholesterol. Most hormones investigated (FSH, LH, TSH and FT4) proved to be stable after 29 years of storage while PRL showed sign of degradation. The observed differences are probably due to long-term storage effects and/or external factors (i.e. diet and smoking). Copyright © 2014 The Canadian Society of Clinical Chemists.

to assess the presence of nonalcoholic fatty liver disease in patients with risk factors for this pathology (obesity, dyslipidemia, metabolic syndrome and diabetes type 2) and to determine the role of insulin, HOMA index, insulin-like growth factor-binding protein-1, sex hormone-binding globulin and plasminogen activator inhibitor type 1, as biochemical markers. Ninety-one patients with risk factors for nonalcoholic fatty liver disease were evaluated. Serum transaminases, insulin, sex hormone-binding globulin, insulin-like growth factor-binding protein-1 and plasminogen activator inhibitor type 1 were measured. The diagnosis of fatty liver was performed by ultrasonography and liver biopsies were performed to 31 subjects who had steatosis by ultrasonography and high alanine aminotransferase. Nonalcoholic fatty liver disease was present in 65 out of 91 patients (71,4%). Liver biopsy performed to 31 subjects confirmed nonalcoholic steatohepatitis. Twenty-five patients had different degrees of fibrosis. Those individuals with fatty liver had higher waist circumference, serum levels of triglycerides, insulin and HOMA index, and lower serum insulin-like growth factor-binding protein-1 concentration. The degree ofhepatic steatosis by ultrasonography was positively correlated to waist circumference, triglycerides, insulin and HOMA index (p<0,003; p<0,003; p<0,002 and p<0,001, respectively), and was negatively correlated to HDL-cholesterol and insulin-like growth factor-binding protein-1 (p<0,025 and p<0,018, respectively). We found a high prevalence of NAFLD in patients with risk factors, most of them overweight or obese. Although SHBG and PAI-1 have a closely relationship to insulin resistance, they did not show to be markers of NAFLD. Regardless of low IGFBP-1 levels associated with NAFLD, serum IGFBP-1 measure is less accessible than insulin and triglycerides levels, HOMA index and waist circumference. Moreover, it is not a better marker for NAFLD than the above
