Sample records for beta-globulins

  1. Serum Proteins and Alkaline Phosphatase Levels in Patients with Tuberous Sclerosis (United States)

    Fischer, M. H.; And Others


    Six 4- to 37-year-old patients with tuberosis sclerosis (a chronic condition characterized by siezures, intercranial calcification, a reddish-yellow sebaceous glandular mass on the face, and frequent crises in early years), did not exhibit an elevation of the (alpha + beta) globulin fraction in their serum.

  2. An electrophoretic study of urinary protein in the rat. (United States)



    The nature of the proteins present in the urine of the normal rat has been investigated by electrophoretic analysis and by fractional precipitation of these proteins by ammonium sulfate. Components similar to serum alpha- and beta-globulin constitute the major portion of the urinary protein in both male and female rats. Following the intraperitoneal injection of renin, a massive proteinuria occurs. The proteins excreted are similar in proportion and electric mobility to those of normal rat serum. PMID:14927799

  3. Serum protein changes in ponies on different parasite control programmes. (United States)

    Herd, R P; Kent, J E


    Serum protein responses were examined in 52 ponies divided into five groups and subjected to various control strategies that resulted in pasture infectivity ranging from 706 to 18,486 infective third stage, cyathostome and Trichostrongylus axei larvae per kilogram of herbage (L3/kg) by 17 September 1984. Major protein changes occurred only in young ponies (Groups 4 and 5) and were observed before exposure to maximum numbers of pasture larvae (Group 4; 10,210 L3/kg, Group 5: 10,042 L3/kg) on 17 September. It appeared that a primary infection of T axei was a greater stimulus to serum beta-globulin and immunoglobulin (Ig)G(T) responses that provided by continued infection with cyathostome (small strongyle) worms. The large strongyles (Strongylus vulgaris, S edentatus and S equinus) were not detected in any larval cultures or on pastures grazed by the young ponies. A fall in beta-globulin and IgG(T) concentrations of Group 5 ponies one month after treatment with ivermectin indicated a larvicidal action against T axei and/or the cyathostomes. A subsequent rise in serum albumin concentrations of Group 5 ponies suggested that a protein-losing gastroenteropathy had been alleviated by the larvicidal action of ivermectin. Mature control ponies (Group 1) showed little beta-globulin response and only a modest IgG(T) response in six of the 10 ponies after exposure to heavily infected lawns (18,486 L3/kg) in September 1984. It was concluded that serum protein and IgG(T) responses were of limited value as an aid to diagnosis of parasitism because of numerous difficulties of interpretation. PMID:3803358

  4. Injection of mice with antibody to interferon renders peritoneal macrophages permissive for vesicular stomatitis virus and encephalomyocarditis virus.


    Belardelli, F.; Vignaux, F; Proietti, E; Gresser, I


    Vesicular stomatitis virus (VSV) and encephalomyocarditis virus (EMCV) multiply in only a small percentage of peritoneal macrophages freshly explanted from 4- to 6-week-old male or female DBA/2, BALB/c, C3H, C57BL/6, or Swiss mice. However, when these mice were injected intraperitoneally with potent sheep (or goat) anti-mouse interferon alpha/beta globulin 4 days prior to harvesting peritoneal macrophages, the viruses multiplied to high titers and most of the cells were infected, as determine...

  5. Data on the isolation of immunoglobulin from the serum of the green frog: Rana esculenta

    Stošić Svetlana


    Full Text Available Even though the green frog (Rana esculenta is often used as an experimental model for further studies of physiological laws, little is still known about its serum proteins and their role in immunity. Its serum proteins have been studied quite extensively, as when they are taken up into the organism of another animal they represent antigens themselves. In this work, an attempt was made to isolate some frog serum proteins and to investigate the electrophoretic qualities of the isolated components (electrophoresis on agar gel and immunoelectrophoresis. IgG was isolated using the same procedure applied for human sera and one of the components found in the beta globulin zone was isolated from frog serum by the same procedure. Immunoelectrophoretic analysis, carried out with the full antiserum of a rabbit, obtained by immunization of the rabbit with the frog serum, showed that the isolated component was pure. The obtained results confirm the fact that there are no slow gamma globulins in the frog serum and point out that this procedure, used for isolating human IgG class, is also suitable for isolating one protein component from the serum of the frog, which has the electrophoretic speed of beta globulin and which may represent one category of frog immunoglobulins.

  6. Some biochemical and hematological changes in female rats under protein malnutrition

    International Nuclear Information System (INIS)

    The aim of this study was to clarify the effect of low and high dietary protein on some biochemical and hematological parameters in blood of female albino rats. A total number of 75 albino female rats were equally divided into 3 groups, the first group was fed 20% protein diet and served as control and the second and third groups were fed 5% and 65% protein for 5 weeks and served as low and high protein dietary groups, respectively. The results showed high significant decreases in serum growth hormone, ferritin levels and iron concentration in group II and there was significant increase in unsaturated iron binding capacity (UIBC) in group III, compared to control group. Studies of total protein and its fractions revealed high significant decreases in total protein, albumin, alpha-1-globulin, beta-globulin as well as gamma globulin in group II and significant increases in total protein, alpha-1- globulin, beta-globulin and gamma-globulin in group III, compared to normal control group. The hematological investigations in group II revealed significant decreases in hemoglobin value, total leukocyte count, platelets, mean corpuscular hemoglobin concentration (MCHC), erythrocytic count and mean corpuscular volume (MCV). On the other hand, there was significant increase in total leukocyte count in group III if compared to control group

  7. Protein and cholesterol electrophoresis of plasma samples from captive cownose ray (Rhinoptera bonasus). (United States)

    Cray, Carolyn; Rodriguez, Marilyn; Field, Cara; McDermott, Alexa; Leppert, Lynda; Clauss, Tonya; Bossart, Gregory D


    Our study was undertaken to assess the application of semiautomated methods available at the reference laboratory level for the evaluation of plasma protein and cholesterol via electrophoresis in samples from cownose rays (Rhinoptera bonasus). Three groups of animals were assessed: clinically normal, clinically abnormal, and parasitized with leeches. As reported previously, the albumin band was negligible; the protein electrophoretograms were dominated by a large beta-globulin fraction. While the group of samples from the leech-parasitized rays did not show any large differences, the abnormal group exhibited significantly elevated total solids and cholesterol levels. The latter was related to a significant increase in very low density lipoprotein levels. The results demonstrate the potential application of these laboratory methods in quantitation of plasma proteins and cholesterol fractions in subclass Elasmobranchii. PMID:26450839

  8. [Immunodiffusion analysis of plasma proteins in the canine family]. (United States)

    Baranov, O K; Iurishina, N A; Savina, M A


    Immunodiffusion studies have been made on the plasma of 9 species (Vulpes vulpes, V. corsak, Alopex lagopus, Canis aureus, C. lupus, C. familiaris, C. dingo, Nyctereutes procynoides, Fennecus zerde) from the family of Canidae using milk antisera. Unlike rabbit antisera used earlier, milk antisera make it possible to detect more significant antigenic divergency with respect to 5 alpha- and beta-globulins. These globulins seem to have a higher evolution rate of antigenic mosaics as compared to other plasma proteins in the family investigated. The family Canidae serologically may be divided into two main groups: 1) the genus Canis which includes the wolf, domestic dog, dingo, jackal and 2) species which significantly differ from the former (the fox, polar fox, dog fox, fennec). In relation to these two groups, the raccoon dog occupies special position. PMID:62473

    Full Text Available Analyses of haematological and biochemical constituents were carried out on the Norwegian subspecies of free-ranging red deer (Cervus elaphus atlanticus. All animals were captured from January to March by using a mixture of xylazine and tiletamin-zolazepam. Immobilisation was performed with plastic projectile syringes fired from a dart gun. Fourteen haematological parameters were analysed. There were no differences in the values between hinds and stags and between adults and calves (P > 0.01. Of the 22 biochemical compounds investigated there was a significant difference (P < 0.01 between calves and adults for lactate dehydrogenase (LD, globulin, beta globulin, gamma globulin, and the minerals Na, K, Mg, Zn, Ca, and P. Differences (P < 0.01 between hinds and stags were found in cholesterol, gamma glutamyl transferase (GGT, alpha-1 globulin, alpha-2 globulin and Cu. The blood values determined in this study can be used as reference values for this red deer subspecies immobilised with a mixture of xylazine-tiletamin-zolazepam for health control and diagnosis of diseases.Abstract in Norwegian /Sammendrag:Hematologiske og biokjemiske parametere er analysert på norsk frittlevende hjort (Cervus elaphus atlanticus.

  10. Identification of Bovine Serum Proteins in Fractions after Gel Filtration Involving the Use Of 131I

    International Nuclear Information System (INIS)

    Fractions of bovine serum separated by agar electrophoresis were extracted with 0.9 % NaCl and labelled with 1311. The radioactively labelled electrophoretic fractions were used as indicators of proteins of interest in the gel filtration of bovine serum in a Sephadex G-200 column. The serum was separated into three parts. The measurement of radioactivity in the eluted fractions revealed a quantitative recovery of albumin in the portion having the lowest elution rate; only a negligible part of the radioactivity of labelled albumin appeared in the part with the highest elution rate. It can be assumed that this radioactivity was fixed on polymerized or complex albumin molecules. The radioactivity of the labelled gamma globulin was found in the first two eluted peaks while, in the case of the alpha and beta globulins, the curves for radioactivity as a function of eluted volume reached maxima in the first and third peaks, with a lower amount of activity being present in the middle peak. Preliminary experiments were also performed with two of the labelled electrophoretic fractions of sheep serum (albumin and α2-globulin, 3.5 - 4 S fraction) in vivo. The time dependence of plasma radioactivity in the case of labelled albumin may be broken down into three exponential terms while, in the case of labelled α2-globulin (fraction eluted in the third peak), it can be represented by only two exponential terms.

  11. Comparative study on some organic compounds an peptide hormones in men infected with hepatitis C- virus using radiometric techniques

    International Nuclear Information System (INIS)

    this thesis aims to study the changes which may occurred in some organic compounds in blood of men either infected with hepatitis C virus (HCV), or having thyroid disorders as well as in patients having thyroid disorders combined with HCV in egypt. HCV considered a dangerous health disease, which infects the human liver leading in some cases to death because there is definite vaccine discovered for HCV. chemical and radiochemical analyses were carried out for all studied groups and the results obtained in men patient groups were compared to those found in normal control group. the results revealed the followings: -some organic compounds in blood especially bilirubin, albumin, total protein, urea were very highly significantly changed due to the infection by HCV. Creatinine was significantly changed in patients with thyroid disorders and infected with HCV. these parameters may be taken as an early diagnostic tool for hepatitis C virus patients and HCV patients with thyroid disorders.- beta globulin was increased in HCV patients as well as gamma globulin especially (1gG and 1gM) which could be used in the diagnosis for HCV infection. - concerning T3,T4 and TSH hormones, statistical analysis revealed that they were very highly significant changed in patients suffering from thyroid diseases with HCV infection

  12. Effects of Meloxicam on Hematologic and Plasma Biochemical Analyte Values and Results of Histologic Examination of Kidney Biopsy Specimens of African Grey Parrots (Psittacus erithacus). (United States)

    Montesinos, Andres; Ardiaca, Maria; Juan-Sallés, Carles; Tesouro, Miguel A


    In this study we evaluated the effects of meloxicam administered at 0.5 mg/kg IM q12h for 14 days on hematologic and plasma biochemical values and on kidney tissue in 11 healthy African grey parrots (Psittacus erithacus). Before treatment with meloxicam, blood samples were collected and renal biopsy samples were obtained from the cranial portion of the left kidney from each of the birds. On day 14 of treatment, a second blood sample and biopsy from the middle portion of the left kidney were obtained from each bird. All birds remained clinically normal throughout the study period. No significant differences were found between hematologic and plasma biochemical values before and after 14 days of treatment with meloxicam, except for a slight increase in median beta globulin and corresponding total globulin concentrations, and a slight decrease in median phosphorus concentration. Renal lesions were absent in 9 of 10 representative posttreatment biopsy samples. On the basis of these results, meloxicam administered at the dosage used in this study protocol does not appear to cause renal disease in African grey parrots. PMID:25867660

  13. Role of zinc-protein complexes in the serum of human beings with reference to health and infectious diseases

    International Nuclear Information System (INIS)

    Serum of one hundred thirty normal subjects and 100 patients of different infections were analysed by electrophoresis and atomic absorption flame spectrophotometric technique. It was found that about sixty percent of zinc is bound to albumin and thirty percent is bound to alpha 2-globulins with a variation of 2-5%, beta-globulins and gamma-globulins with a variation of 2-5% in different normal subjects. While the determination of zinc in patients of different infections shows 20-30% decrease in the concentration of albumin bound zinc. The concentration of zinc in alpha 2-globulins remains the same in normal subjects as well as in patients of different infections. The results indicate that in low nourished normal subjects, there is a low concentration of zinc complexes of albumin and a greater chance of different infectious diseases it was further known that albumin works for the transport of zinc and possibly, alpha 2-globulins plays on intermediate role for the attachment of zinc to different body organs. From the above determinations, it is clear that it is the low concentration of zinc in normal subjects which favours the attack of infectious disease. So higher levels of zinc in serum means more resistance towards the attack of infectious diseases. (author)

  14. Effect Of Dried Whey Milk Supplement On Some Blood Biochemical And Immunological Indices In Relation To Growth Performance Of Heat Stressed Bovine baladi Calves

    International Nuclear Information System (INIS)

    This experiment was carried out under hot environmental conditions, where temperature-humidity index was equivalent to 86 - 90 and 78 - 80 during day and night, respectively. Twelve bovine Baladi calves of 8 - 10 months old and 112 kg average initial live body weight were used in this study. The calves were divided into two groups of 6 animals each to study the effect of supplementation of dried whey milk on some blood biochemical and immunological indices and growth performance of calves under hot weather conditions of Egypt. The results showed that supplementation of dried whey milk to the diet of heat-stressed calves at the level of 150 g / calf / day reduced significantly each of respiration rate and rectal temperature as well as serum lipid concentrations and their fractions e.g. total cholesterol and phospholipids. Also, dried whey milk supplement caused a significant decline in both AST and ALT activities and reduced significantly alpha globulin concentration, while non-significant changes were observed in each of beta globulin, gamma globulin and immunoglobulin G. However, supplementing dried whey milk to growing calves increased significantly serum concentrations of total protein, albumin, calcium, phosphorous, T3 and T4 . Moreover, dried whey milk improved significantly both feed efficiency and daily gain of growing calves. It could be concluded that addition of dried whey milk to the diet reduced rectal temperature and respiration rate and induced an improvement in most blood biochemical parameters and growth performance of heat-stressed bovine Baladi calves.

  15. Transfer of radioactive iron through the placenta in animals and man

    International Nuclear Information System (INIS)

    The following results apply to the mammals with haemochorial placenta investigated so far as well as to man: Within a few minutes after injection of radioactive iron compounds into the mother's blood circulation, activity can be verified in the fetus. When several fetuses exist, the degree of activity may vary from one fetus to another. Iron to supply the fetus is not provided by hemoglobin; when it reaches the placental barrier it is bound to beta-globulin. Iron is only transported in the directions from mother to fetus. The concentration of radioactive iron in the fetal serum exceeds that of the mother's serum within minutes of the injection. This presupposes an active transport mechanism at the placenta and the fetus accumulates radioactive iron most of all in the liver; these reserves are formed with a view to compensate low iron supply during lactation. Because in rabbits the greatest number of important parameters was found to be identical with man as regards diaplacental transfer, this species seems to be the most appropriate model to elucidate the diaplacental passage of suitable radionuclide compounds in man.

  16. Age-associated changes in the immune system of German shepherd dogs. (United States)

    Strasser, A; Teltscher, A; May, B; Sanders, C; Niedermüller, H


    In order to look into the ageing of the canine immune system we investigated age-related changes and associated gender-related differences in parameters of innate and acquired immunity in German Shepherd dogs. We obtained the following findings: white blood cell counts, peripheral blood lymphocytes, lymphocyte proliferative activity and interleukin-2 (IL-2) serum concentrations were significantly lower in the group of old animals, whereas the concentrations of gamma-globulins and the functional activity of the complement system were significantly higher in the elderly. Phagocytic and bactericidal activity of polymorphonuclear cells, as well as their 'killing function,' the serum cytokine-like activities of tumour necrosis factor-alpha and the plasma concentrations of immunoglobulin G, as well as of alpha- and beta-globulins, were not significantly affected by age, whereas natural killer-cell activity and the serum cytokine-like activities of IL-1 were significantly higher only in the group of female old animals. With regard to gender-related differences, lymphocyte proliferative activities as well as plasma concentrations of alpha-globulin were significantly higher in the group of female animals, whereas the absolute numbers of segmented neutrophils were significantly lower. Species analogies with regard to ageing as presumed to exist between man and laboratory rodents also seem to be applicable to the dog. The observed age-related changes in the canine immune system are probably among the main causes for the multimorbidity of old age, affecting life expectancy and mortality in the dog and should be recognized and considered by the attending veterinarian.

  17. Serum biochemistry and electrophoretic patterns in the Eurasian Buzzard (Buteo buteo): reference values. (United States)

    Gelli, D; Ferrari, V; Franceschini, F; Lai, O; Laricchiuta, P; Zanella, A; Bernardini, D; Romagnoli, S


    In avian medicine, hematologic and biochemical laboratory investigations are still in their infancy, because of the difficulty involved in collecting data. This has led to a lack of reference values and a nonstandardized approach to specimens obtained in critical conditions. The Eurasian Buzzard (Buteo buteo) is one of the most common raptors in Italy, yet little is known about the physiologic blood parameters of this species. Serum biochemistry and electrophoretic investigations were performed in 40 healthy Eurasian Buzzards in different Italian wildlife rescue centers waiting to be released after recovering from trauma injuries. Mean values for biochemistry parameters were pancreatic amylase 626.9 IU/l, uric acid 7.5 mg/dl, aspartate aminotransferase 330.9 IU/l, glucose 375.1 mg/dl, lipase 26.3 IU/ l, total protein 38.4 g/l, total bilirubin 0.04 mg/ dl, lactate dehydrogenase 2,008.4 IU/l, creatinine kinase 1,604.1 IU/l, alanine aminotransferase 40.4 IU/l, alkaline phosphatase 89.8 IU/l, magnesium 2.3 mg/dl, calcium 10.2 mg/dl, phosphorus 2.02 mg/dl, cholesterol 192.2 mg/ dl, triglyceride 116.4 mg/dl, albumin 14.5 g/l, creatinine 0.1 mg/dl. Mean electrophoretic values were prealbumin 1.4 g/l, albumin 14.2 g/l, alpha 1 globulin 5.9 g/l, alpha 2 globulin 4.7 g/l, beta globulin 7.5 g/l, gamma globulin 3.6 g/l, albumin/globulins ratio 0.8 g/l.

  18. Prediction of respiratory disease and diarrhea in veal calves based on immunoglobulin levels and the serostatus for respiratory pathogens measured at arrival. (United States)

    Pardon, Bart; Alliët, Jeroen; Boone, Randy; Roelandt, Sophie; Valgaeren, Bonnie; Deprez, Piet


    Failure of passive transfer is a common problem in calves destined for veal production. At present it is unknown whether the risk for respiratory disease (BRD) or neonatal calf diarrhea (NCD) in the veal herd is associated with total immunoglobulin (Ig) and/or on the serostatus for respiratory pathogens measured at arrival. Therefore, the first objective of this prospective longitudinal cohort study was to determine associations between serum protein fractions as determined by routine electrophoresis (total protein, albumin, alpha-1 and -2 globulins, beta-globulins and Ig's) at arrival and BRD and NCD in the first 3 weeks of the production cycle. The second objective was to determine whether the serostatus (seropositive/seronegative) of seven respiratory pathogens (bovine respiratory syncytial virus (BRSV), parainfluenzavirus-3, bovine coronavirus (BCV), bovine herpesvirus-1, bovine viral diarrhea virus, Mannheimia haemolytica and Mycoplasma bovis) of these arrival serum samples could be associated with the risk of having BRD. The third objective was to determine which of the electrophoresis proteins and respiratory serostatuses were associated with average daily gain (ADG) in the study period. The study population consisted of 150 rosé veal calves housed in a single air-space. The study period ended at day 18 post arrival, when BRD incidence was judged to be too high to further postpone a group treatment. A Cox regression model was used to determine the effect of the studied protein fractions and antibodies on the time to BRD and NCD occurrence. The effect of the studied predictors on ADG was determined by linear regression. Calves with Ig levels under 7.5g/L had an increased BRD hazard (hazard ratio (HR)=1.9 (95% confidence interval (CI)=1.2-3.0)). NCD was only positively associated with the alpha-2 globulin concentration. Calves with a negative serostatus for BCV (HR=1.7 (95% CI=1.0-2.8)) or BRSV (HR=2.0 (95% CI=1.0-3.9)) had an increased BRD hazard. Average

  20. Isolation of plasma lipoproteins by zonal ultracentrifugation in the B14 and B15 titanium rotors. (United States)

    Wilcox, H G; Heimberg, M


    Lipoproteins were isolated from plasma of man, dog, rabbit, rat, and chicken by ultracentrifugation in continuous density gradients using the B14 titanium and B15 titanium zonal rotors. Both the VLDL and the LDL of human plasma were separated easily from the HDL and from the other more plentiful plasma proteins by centrifugation for only 1 or 2 hr in the B14 or B15 rotor, respectively. Satisfactory separation of the HDL from the more dense plasma proteins was not achieved with these rotors. The human LDL achieved isopycnic equilibrium (d 1.04) on prolonged periods (> 24 hr) of centrifugation in a sucrose-KBr density gradient. The pattern of distribution of cholesterol and phospholipid throughout the density gradient coincided with the pattern of distribution of the lipoprotein-protein measured spectrophotometrically or chemically. The concentration of cholesterol and phospholipid in the lipoproteins isolated by zonal ultracentrifugation agreed with analyses reported for lipoproteins isolated by sequential centrifugation in solutions of increasing density. The lipoproteins isolated by zonal ultracentrifugation were characterized further by their electrophoretic behavior. The fractions which were identified as the LDL (d 1.04-1.05) from all species migrated on paper as a beta-globulin; the LDL from plasma of dogs contained an additional component which has been designated as an alpha(2)-globulin. The fractions which were identified as the HDL from all species migrated as an alpha(1)-globulin. Reaction of human LDL with either rabbit antihuman beta-lipoprotein or rabbit antihuman serum resulted in a single immunodiffusion band. The S(f, 1.063) of the human LDL was calculated to be 6.0. When plasma from humans or rabbits was centrifuged in the B15 rotor, the HDL was not visible as a distinct peak and was not separable from the bulk of the more dense plasma proteins; when plasma from dogs or chickens was centrifuged under identical conditions, the HDL was clearly

    . So, the evaluation of the changes that may be considered proper to the CSF in the post-mortem was carried out only in the samples presenting no more then 1,000 hematiae per mml. Normal white cells number was proportionally more common in the third group of cases. Pleocytosis was more frequently found than normal cell count. It was slight or discrete in most of the cases. More than 50 white cells per mml were found in the samples collected from cases in which the patients had died in the course of acute infections. Low concentrations of chloride and glycosis were found in most of the cases and they tended to be lower with the increase of TOC. Hipoglycorrhachia was found to be more intense in the cases with pleocytosis. The concentration of urea was high in most of the cases; the increase of urea contents was at the same range in the three groups of cases considered. High GOT and GPT activities were found in several cases and the TOC appeared to influence the increase of these activities. This influence was more conspicuous in the last group only for GPT. Total protein concentrations above normal were frequent. They tended to be more conspicuously elevated with the increasing of TOC. The protein profiles were marked by the inversion of albumin/globulins ratio. They tended to be of the mixed type, with increase in the alpha and/or gamma globulins participation. The gamma globulin increase was more frequently observed. The increase of these globulin fractions was more conspicuous in the cases refering to patients who died during infectious diseases. An increase of the beta globulin fraction was observed in four cases: in two the death occurred in the course of hepatic cyrrhosis and, in two, of neoplasies. The influence of TOC on the protein profile changes was discrete: with the increase of the TOC the participation of gamma globulin increased and that of beta globulin decreased. The aspects of CSF composition here considered allow the conclusion that many of the changes
