    Full Text Available Atherosclerosis, a chronic and progressive disease characterized by vascular inflammation, is a leading cause of death in diabetes patients. Doinseunggitang (DYSGT, traditional prescription, has been used for promoting blood circulation to remove blood stasis. The aim of this study was to investigate the beneficial effects of DYSGT on endothelial dysfunction in diabetic atherosclerosis animal model. Apolipoprotein E knockout (ApoE KO mice fed on a Western diet were treated with DYSGT (200 mg/kg/day. DYSGT significantly lowered blood glucose level and glucose tolerance as well as systolic blood pressure. Metabolic parameter showed that DYSGT markedly decreased triglyceride and LDL-cholesterol levels. In the thoracic aorta, the impairment of vasorelaxation response to acetylcholine and atherosclerotic lesion was attenuated by DYSGT. Furthermore, DYSGT restored the reduction of endothelial nitric oxide synthase (eNOS expression, leading to the inhibition of intracellular adhesion molecule-1 (ICAM-1 and endothelin-1 (ET-1 expression. In conclusion, DYSGT improved the development of diabetic atherosclerosis via attenuation of the endothelial dysfunction, possibly by inhibiting ET-1, cell adhesion molecules, and lesion formation. Therefore, these results suggest that Korean traditional prescription Doinseunggitang may be useful in the treatment and prevention of diabetic vascular complications.

    Vanadium compounds have been recognized for their hypoglycemic effects; however, potential short and long-term vanadium toxicity has slowed the acceptance for therapeutic use. In the present work, three batches of vanadium-enriched chickpea sprout (VCS) were prepared by incubating chickpea seeds in presence of 200, 100, and 50 microg/ml of sodium orthovanadate (SOV). The effects of oral administration of chickpea sprout (CS) and VCS food for 8 weeks on streptozotocin-induced (STZ) diabetic rats were investigated. Both CS and VCS food was found to ameliorate some hyperglycemic symptoms of the diabetic rats, i.e. improve lipid metabolism, decrease blood glucose level, prevent body weight loss, and reduce impairment of diabetic related spatial learning and memory. Serum insulin was substantially elevated in treated diabetic rats, which is probably one important reason for the hypoglycemic effect. Compared with CS alone, VCS100 food exhibited remarkably enhanced effectiveness in alleviating diabetes induced hyperglycemia and memory loss. Moreover, vanadium-enriched chickpeas appeared to abolish the vanadium induced toxicity associated with administration of this metal for diabetes during the 8-week study period. This study suggested further work of the vanadium speciation in CS and novel hypoglycemic mechanism for the antidiabetic activity of vanadium agents. Vanadium containing (VCS) food could be a dietary supplement for the diabetic status.

    Full Text Available The protective action against oxidative stress of red cabbage (Brassica oleracea extract was investigated. Diabetes was induced in male Wistar rats using streptozotocin (60 mg/kg body weight. Throughout the experimental period (60 days, diabetic rats exhibited many symptoms including loss of body weight, hyperglycemia, polyuria, polydipsia, renal enlargement and renal dysfunction. Significant increase in malondialdehyde, a lipid peroxidation marker, was observed in diabetic kidney. This was accompanied by a significant increase in reduced glutathione and superoxide dismutase activity and a decrease in catalase activity and in the total antioxidant capacity of the kidneys. Daily oral ingestion (1 g/kg body weight of B. oleracea extract for 60 days reversed the adverse effect of diabetes in rats. B. oleracea extract lowered blood glucose levels and restored renal function and body weight loss. In addition, B. oleracea extract attenuated the adverse effect of diabetes on malondialdehyde, glutathione and superoxide dismutase activity as well as catalase activity and total antioxidant capacity of diabetic kidneys. In conclusion, the antioxidant and antihyperglycemic properties of B. oleracea extract may offer a potential therapeutic source for the treatment of diabetes.

    Full Text Available Objective(s:Previous research demonstrated that diabetes is one of the leading causes of learning and memory deficits. Naringin, a bioflavonoid isolated from grapefruits and oranges, has potent protective effects on streptozotocin (STZ-induced diabetic rats. Recently, the effects of naringin on learning and memory performances were monitored in many animal models of cognitive impairment. However, to date, no studies have investigated the ameliorative effects of naringin on diabetes-associated cognitive decline (DACD. In this study, we investigated the effects of naringin, using a STZ-injected rat model and explored its potential mechanism. Materials and Methods:Diabetic rats were treated with naringin (100 mg/kg/d for 7 days. The learning and memory function were assessed by Morris water maze test. The oxidative stress indicators [superoxide dismutase (SOD and malondialdehyde (MDA] and inflammatory cytokines (TNF-a, IL-1β, and IL-6 were measured in hippocampus using corresponding commercial kits. The mRNA and protein levels of PPARγ were evaluated by real time (RT-PCR and Western blot analysis. Results:The results showed that supplementation of naringin improved learning and memory performances compared with the STZ group. Moreover, naringin supplement dramatically increased SOD levels, reduced MDA levels, and alleviated TNF-α, IL-1β, and IL-6 compared with the STZ group in the hippocampus. The pretreatment with naringin also significantly increased PPARγ expression. Conclusion: Our results showed that naringin may be a promising therapeutic agent for improving cognitive decline in DACD.

  10. Qigong Ameliorates Symptoms of Chronic Fatigue: A Pilot Uncontrolled Study

    Directory of Open Access Journals (Sweden)

    Naropa J. Mike Craske

    2009-01-01

    Full Text Available Traditional Chinese Medicine practitioners consider that chronic fatigue reflects a disharmony and depletion in the supply of qi in the body. Qigong is one of the traditional complementary interventions used to strengthen qi through self-practice, and to manage the state of qi to prevent and cure disease. The aim of this study is to assess whether qigong could be used to manage the symptoms of chronic fatigue. Eighteen Caucasian, British female participants were recruited, taught a qigong routine during weekly classes over 6 months, and asked to practice it daily for 15 min. Participants completed the core set of the RAND Medical Outcomes Study questionnaire (RAND MOS and a sleep diary during the 2-week baseline control period, and at 3 and 6 months following the start of the trial. The qigong intervention resulted in significant changes in sleep rate score and in the following subscales of the RAND MOS: SF36 Vitality, Sleep Problems, Social Activity, Social Activity Limitation due to Health, Health Distress, Mental Health Index and Psychological Well-being. Qigong seems to improve factors related to chronic fatigue such as sleep, pain, mental attitude and general mobility after 3 and 6 months. Qigong's positive effects indicate that it represents a potentially safe method of treatment for chronic fatigued patients. However, we cannot completely discount the possible influence of placebo effects, and more objective clinical measures are needed to reproduce our findings with long-term follow-up in a randomized, controlled study involving a larger number of subjects.

    2005-06-01

    The potential of dietary potato peel (PP) powder in ameliorating oxidative stress (OS) and hyperglycemia was investigated in streptozotocin (STZ)-induced diabetic rats. In a 4-week feeding trial, incorporation of potato peel powder (5 and 10%) in the diet of diabetic rats was found to significantly reduce the plasma glucose level and also reduce drastically the polyuria of STZ diabetic rats. The total food intake was significantly reduced in the diabetic rats fed 10% PP powder compared to the control diabetic rats. However, the body weight gain over 28 days was nearly four times greater in PP powder supplemented diabetic rats (both at 5 and 10%) compared to the control diabetic rats. PP powder in the diet also decreased the elevated activities of serum transaminases (ALT and AST) and nearly normalized the hepatic MDA and GSH levels as well as the activities of specific antioxidant enzymes in liver of diabetic rats. The result of these studies clearly establishes the modulatory propensity of PP against diabetes induced alterations. Considering that potato peels are discarded as waste and not effectively utilized, these results suggest the possibility that PP waste could be effectively used as an ingredient in health and functional food to ameliorate certain disease states such as diabetes.

    Infusion of mesenchymal stem cells (MSCs) has been shown to effectively lower blood glucose in diabetic individuals, but the mechanism involved could not be adequately explained by their potential role in promoting islet regeneration. We therefore hypothesized that infused MSCs might also contribute to amelioration of the insulin resistance of peripheral insulin target tissues. To test the hypothesis, we induced a diabetic rat model by high-fat diet/streptozotocin (STZ) administration, perfor...

    This study was designed to assess anti-diabetic potential of goat, camel, cow and buffalo milk in streptozotocin (STZ) induced type 1 diabetic albino wistar rats. A total of 48 rats were taken for the study where one group was kept as non-diabetic control group (8 rats) while others (40 rats) were made diabetic by STZ (50 mg/kg of body weight) injection. Among diabetic rats, a control group (8 rats) was kept and referred as diabetic control whereas other four groups (8 rats each) of diabetic rats were fed on 50 ml of goat or camel or cow or buffalo milk for 4 weeks. All the rats (non-diabetic and diabetic) were maintained on standard diet for four weeks. STZ administration resulted in enhancement of glucose, total cholesterol, triglyceride, low density lipoprotein, HbA1c and reduction in high density lipoprotein in plasma and lowering of antioxidative enzymes (catalase, glutathione peroxidase and superoxide dismutase) activities in pancreas, kidney, liver and RBCs, coupled with enhanced levels of TBARS and protein carbonyls in pancreas, kidney, liver and plasma. OGTT carried out at the end of 4 week milk feeding indicated that all milks helped in early maintenance of glucose level. All milks reduced atherogenic index. In camel milk fed diabetic group, insulin concentration enhanced to level noted for non-diabetic control while goat, cow and buffalo milk failed to restore insulin level. HbA1c level was also restored only in camel milk fed diabetic group. The level of antioxidative enzymes (catalase, GPx and SOD) in pancreas enhanced in all milk fed groups. Camel milk and to a reasonable extent goat milk reduced formation of TBARS and PCs in tissues and blood. It can be concluded that camel milk ameliorates hyperglycaemia and oxidative damage in type-1 diabetic experimental rats. Further, only camel milk completely ameliorated oxidative damage in pancreas and normalised insulin level. PMID:27600979

    Full Text Available Diabetes mellitus (DM is a metabolic disease that involves disorders such as diabetic retinopathy, diabetic neuropathy, and diabetic hearing loss. Recently, neurotrophin has become a treatment target that has shown to be an attractive alternative in recovering auditory function altered by DM. The aim of this study was to evaluate the effect of DA9801, a mixture of Dioscorea nipponica and Dioscorea japonica extracts, in the auditory function damage produced in a STZ-induced diabetic model and to provide evidence of the mechanisms involved in enhancing these protective effects. We found a potential application of DA9801 on hearing impairment in the STZ-induced diabetic model, demonstrated by reducing the deterioration produced by DM in ABR threshold in response to clicks and normalizing wave I–IV latencies and Pa latencies in AMLR. We also show evidence that these effects might be elicited by inducing NGF related through Nr3c1 and Akt. Therefore, this result suggests that the neuroprotective effects of DA9801 on the auditory damage produced by DM may be affected by NGF increase resulting from Nr3c1 via Akt transformation.

    Full Text Available Virgin coconut oil (VCO is a saturated fat with promising antidiabetic properties but its ameliorative effect on lipid profiles in diabetics is rarely reported. Therefore, in this study, a total of fifteen (15 male rats weighing 200–250 g were divided into 3 experimental groups (n=5. Group I (control and Group II (diabetic control group were fed a normal rat chow while Group III (diabetic test group was fed a 10% VCO diet for 3 weeks. Group II and Group III were made diabetic by intraperitoneal injection of 150 mg/kg of alloxan. After 72 hours of injection, blood glucose was tested to confirm diabetes mellitus. After 3 weeks, the animals were sacrificed to collect blood samples for lipid profile analysis. The results showed a significant increase in concentrations of triglyceride, total cholesterol, low density lipoprotein, and very low density lipoprotein and decrease in concentration of high density lipoprotein in Group II when compared to Group I. Also, the concentrations of triglyceride, total cholesterol, low density lipoprotein, and very low density lipoprotein except high density lipoprotein significantly reduced in Group III when compared to Group II (P<0.01, 0.001. VCO consumption can be claimed to ameliorate lipid levels in diabetes mellitus.

  20. Curcumin ameliorates gastrointestinal dysfunction and oxidative damage in diabetic rats

    Full Text Available Diabetes is known to be associated with gastrointestinal complications characterized by nausea, vomiting, early satiety, bloating, and abdominal discomfort or pain commonly occurring in the advanced stages of the disease. Curcumin is the lipid-soluble antioxidant obtained from the rhizomes of Curcuma longa Linn, also known as turmeric. Curcumin targets multiple chemotherapeutic and oxidative stress pathways and has demonstrated safety and tolerability in humans, supporting its potential as a therapeutic agent; however, literature lacks conclusive evidence supporting its use as a therapeutic agent for the treatment of diabetes induced gastrointestinal complications. Hence, Curcumin was given in different doses to SD rats after 4 weeks of diabetic GI complication induction. At the end of 4 weeks, significant GI dysfunction characterized by weight loss, delayed gastric emptying and intestinal transit associated with reduction in antioxidant enzyme levels and increased lipid peroxidation was observed.  Upon treatment with Curcumin for further 4 weeks, reversal of GI dysfunction evidenced by restoration of body weight, GI emptying, intestinal transit, and restoration of antioxidant enzyme level and lipid peroxidation proves the beneficial role of Curcumin in diabetes induced GI complications due to its antioxidant potential.

  2. Are gastrointestinal symptoms related to diabetes mellitus and glycemic control?

    Science.gov (United States)

    Koch, Christian A; Uwaifo, Gabriel I

    2008-09-01

    Many patients with diabetes mellitus suffer from upper and lower GI symptoms. The reported prevalence of these symptoms varies among different ethnic groups/populations. The natural history of GI symptoms as well as their pathogenesis in patients with diabetes remains poorly understood, although it is known that gastric emptying is influenced by hyperglycemia, euglycemia, and hypoglycemia. Poor glycemic control over a long period of time can lead to neuropathy and damage the vagus nerve, resulting in diabetic gastroparesis whose signs and symptoms vary in the individual patient. Gastroparesis can further worsen glycemic control by adversely altering the pharmacokinetics of orally administered hypoglycemic agents as well as by altering the delivery of diet-derived calories to intestines from which absorption, subsequently, determines incipient blood glucose, and thus effectiveness of various injectable antidiabetics including various insulins and related insulin analogs. As GI symptoms may overlap with other disorders, including functional dyspepsia, irritable bowel syndrome, and depression, it is important to have such patients/patients with diabetes undergo standardized testing for measuring gastric emptying. Certain medications including metformin, amylin analogues (i.e. pramlintide), glucagon-like peptide 1 analogs (i.e. exenatide, liraglutide), anticholinergic agents, antidepressants, calcium-channel blockers, and others may contribute to GI symptoms observed in patients with diabetes. Given the global diabetes pandemic, it is of utmost importance to not only diagnose and treat present patients with diabetes mellitus and its comorbidities, but also to help prevent the development of further disease burden by educating children and adolescents about healthy lifestyle modifications (avoidance of overeating, portion control, healthy food choices, increased physical and reduced sedentary activity), as changing behavior in adulthood has proven to be notoriously

    Full Text Available Background: Diabetes leads to a cardiomyopathy characterized by myocyte loss. Streptozotocin (STZ-induced diabetic cardiomyopathy is characterized by decreased left ventricular contractility and diminished ventricular compliance with marked abnormal systolic and diastolic function. Aim: The ameliorative effect of ethanolic Gymnema sylvestre extract (GSE was evaluated in diabetic cardiomyopathy against STZ-induced diabetes. Materials and Methods: Diabetes was induced by a single intravenous injection of (STZ, 45 mg/kg in male Wistar rats. Blood pressure, serum lactate dehydrogenase (LDH, glucose apolipoprotein B and lipids as well as heart weight, caspase-3, sodium potassium adenosine triphosphatase Na + K + ATPase, and DNA laddering were determined. Results and Conclusions: Administration of GSE (120 mg/kg/p.o. treatment significantly ( P < 0.01 reduced myocyte loss by suppressing the levels of cardiac caspase-3, DNA laddering; mean arterial blood pressure and heart rate as well as serum LDH, glucose, apolipoprotein B, and lipids levels. Further, it increased the heart weight and cardiac Na + K + ATPase activity in diabetic rats. The cardiomyopathy suppression is accompanied by decrease in cardiac caspase-3 levels, DNA laddering, blood pressures, serum LDH, apolipoprotein-B and glucose. Thus, this present study reports the anti-apoptotic potential of GSE in STZ-induced diabetic cardiomyopathy.

    Copper (Cu) is essential for our daily life and it is found at approximately 110 mg in human adults with the body weight of 70 kg, in which this metal occurs at 46 mg in the bone and 26 mg in the muscle. Although Cu exists in the brain (approximately 5 mg/kg), liver (6 mg/kg), kidney (13 mg/kg), erythrocytes (90 mg/L), bile (6 mg/L) and serum (120 mg/L), its organ-specific distribution is not yet known. In metalloenzymes such as oxidoreductases, Cu is abundantly found and greatly contributes in life functions. In addition, intracellular Cu transport system has been revealed in connection with iron (Fe) and zinc (Zn) intracellular transport systems. In spite of such great contribution of Cu in life, no Cu-containing pharmaceutics have yet been known. Under such background, the author and his research group have tried to examine a possibility of Cu compounds as potential pharmaceutics. In the review, the following topics are concerned; (1) improvement of cardiovascular dysfunction in animals by di-nuclear Cu-asprinate complex on the basis of the results on its reactive oxygen scavenging (ROS) effect, (2) blood glucose-lowering effect of mono-nuclear Cu-picolinate complex in streptozotocin (STZ)-induced type 1-like diabetic animals, based on the results on in vitro insulinomimetic activity, and (3) anti-diabetic effect of copper sulfate in animals with regard to the inhibition of α-glucosidase activity. These results suggest that copper ion and its complexes are possible seeds for developing Cu-containing pharmaceutics in the future.

    Full Text Available Background. Although numerous reports addressing pathological involvements of diabetic polyneuropathy have been conducted, a universally effective treatment of diabetic polyneuropathy has not yet been established. Recently, regenerative medicine studies in diabetic polyneuropathy using somatic stem/progenitor cell have been reported. However, the effectiveness of these cell transplantations was restricted because of their functional and numerical impairment in diabetic objects. Here, we investigated the efficacy of treatment for diabetic polyneuropathy using angioblast-like cells derived from mouse embryonic stem cells. Methods and Results. Angioblast-like cells were obtained from mouse embryonic stem cells and transplantation of these cells improved several physiological impairments in diabetic polyneuropathy: hypoalgesia, delayed nerve conduction velocities, and reduced blood flow in sciatic nerve and plantar skin. Furthermore, pathologically, the capillary number to muscle fiber ratios were increased in skeletal muscles of transplanted hindlimbs, and intraepidermal nerve fiber densities were ameliorated in transplanted plantar skin. Transplanted cells maintained their viabilities and differentiated to endothelial cells and smooth muscle cells around the injection sites. Moreover, several transplanted cells constructed chimeric blood vessels with recipient cells. Conclusions. These results suggest that transplantation of angioblast like cells induced from embryonic stem cells appears to be a novel therapeutic strategy for diabetic polyneuropathy.

    Full Text Available Given that oxidative stress plays a major role in pancreatic β-cell dysfunction and ultimate destruction, as well as in different complications of diabetes, therapy with antioxidants has assumed an important place in diabetes management. The relatively limited effects of established antioxidant compounds have stimulated efforts to develop new therapeutic strategies, e.g. to increase the endogenous antioxidant defenses through pharmacological modulation of key antioxidant enzymes. Plant extracts are gaining popularity in treating diabetes because many substances synthesized by higher plants and fungi possess antioxidant activities and can prevent or protect tissues against the damaging effects of free radicals. This review summarizes experimental models of diabetes and possible mechanisms that lie behind the antioxidative effects of α-lipoic acid (LA, a powerful antioxidant and compound that stimulates cellular glucose uptake, as well as of plant extracts from sweet chestnut (Castanea sativa, edible mushroom (Lactarius deterrimus and natural products containing β-glucans in the treatment of diabetes. Their roles in preventing pancreatic β-cell death and in ameliorating the effects of severe diabetic complications are discussed. [Projekat Ministarstva nauke Republike Srbije, br. 173020

    Full Text Available Diabetes is a chronic endocrine disorder associated with several complications as hypertension, advanced brain aging, and cognitive decline. Accumulation of advanced glycation end products (AGEs is an important mechanism that mediates diabetic complications. Upon binding to their receptor (RAGE, AGEs mediate oxidative stress and/or cause cross-linking with proteins in blood vessels and brain tissues. The current investigation was designed to investigate the effect of agents that decrease AGEs signaling, perindopril which increases soluble RAGE (sRAGE and alagebrium which cleaves AGEs cross-links, compared to the standard antidiabetic drug, gliclazide, on the vascular and central nervous system (CNS complications in STZ-induced (50 mg/kg, IP diabetes in rats. Perindopril ameliorated the elevation in blood pressure seen in diabetic animals. In addition, both perindopril and alagebrium significantly inhibited memory decline (performance in the Y-maze, neuronal degeneration (Fluoro-Jade staining, AGEs accumulation in serum and brain, and brain oxidative stress (level of reduced glutathione and activities of catalase and malondialdehyde. These results suggest that blockade of AGEs signaling after diabetes induction in rats is effective in reducing diabetic CNS complications.

    Full Text Available Aims. To evaluate the effect of Punica granatum (Pg rind extract and its spray dried biopolymeric dispersions with casein (F1 or chitosan (F2 against Diabetes mellitus (DM and diabetic neuropathy (DN. Methods. We measured the acute (6 h and subacute (8 days effect of various doses of Pg, F1, and F2 and the active compounds on alloxan-induced DM mouse model. We evaluated DN utilizing latency tests for longer period of time (8 weeks. In addition, the in vivo antioxidant activity was assessed utilizing serum catalase level. Results. The results proved that the highest dose levels of Pg extract, F1, F2 exerted remarkable hypoglycemic activity with 48, 52, and 40% drop in the mice glucose levels after 6 hours, respectively. The tested compounds also improved peripheral nerve function as observed from the latency tests. Bioguided fractionation suggested that gallic acid (GA was Pg main active ingredient responsible for its actions. Conclusion. Pg extract, F1, F2, and GA could be considered as a new therapeutic potential for the amelioration of diabetic neuropathic pain and the observed in vivo antioxidant potential may be involved in its antinociceptive effect. It is highly significant to pay attention to Pg and GA for amelioration and control of DM and its complications.

    Between their broad spectrum of action, vanadium compounds are shown to have insulin mimetic/enhancing effects. Increasing evidence in experimental and clinical studies suggests that oxidative stress plays a major role in the pathogenesis of diabetes and on the onset of diabetic complications. Thus, preventive therapy can alleviate the possible side effects of the disease. The aim of the present study was to investigate the effect of vanadyl sulfate supplementation on the antioxidant system in the stomach tissue of diabetic rats. Male Swiss albino rats were randomly divided into 4 groups: control; control+vanadyl sulfate; diabetic; diabetic+vanadyl sulfate. Diabetes was induced by intraperitoneal injection of streptozotocin (STZ; 65 mg/kg body weight). Vanadyl sulfate (100 mg/kg body weight) was given daily by gavage for 60 days. At the last day of the experiment, stomach tissues were taken and homogenized to make a 10% (w/v) homogenate. Catalase (CAT), superoxide dismutase (SOD), glutathione reductase (GR), glutathione peroxidase (GPx), glutathione-S-transferase (GST), myeloperoxidase (MPO), carbonic anhydrase (CA), glucose-6-phosphate dehydrogenase (G6PD) and lactate dehydrogenase (LDH) activities were determined in the stomach tissue. CAT, SOD, GR, GPx, GST, CA, G6PD and LDH activities were increased in diabetic rats when compared to normal rats. Vanadium treatment significantly reduced the elevated activities of GR, GPx, GST compared with the diabetic group whereas the decreases in CAT, SOD, CA, G6PD and LDH activities were insignificant. No significant change was seen for MPO activity between the groups. It was concluded that vanadium could be used for its ameliorative effect against oxidative stress in diabetes. PMID:24856383

    Background Category Ⅲ chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common syndrome of unclear etiology with significant impact on quality of life. Because the outcomes of multiple therapies for CP/CPPS have been far from approving, the possible psychological factors have been considered to play an important role in CP/CPPS.Based on this, we investigated the role of antidepressant drug (fluoxetine) in men with refractory CP/CPPS.Methods In this study, 42 men diagnosed with refractory CP/CPPS without response to standard therapy (include multiple antibiotic courses and a-blockers) were referred for fluoxetine therapy. All patients received fluoxetine (20 mg/d) for three months and were clinically evaluated before (baseline), and after 4, 8 and 12 weeks of therapy. The evaluation included a National Institutes of Health-chronic prostatitis symptom index (NIH-CPSI) and a Beck depression inventory (BDI) questionnaire. Moreover, the subjective global assessment (SGA) was assessed at the 4th, 8th and 12th week of therapy.Results Significant decreases were observed for total NIH-CPSI (28.55 to 9.29), NIH-CPSI pain (14.69 to 5.19),NIH-CPSI urinary (4.95 to 1.88 ), NIH-CPSI quality of life (8.83 to 2.20), and BDI (34.67 to 13.95) scores compared with baseline, all P values <0.05. Twenty-nine (69.05%) reported marked improvement on the subjective global assessment and 33 (78.57%) had a greater than 50% decrease in NIH-CPSI at the end of therapy (12th week). At the same time, the Pearson correlation coefficient analysis demonstrated a positive correlation between BDI score and each CPSI score. No adverse events were reported in this study.Conclusions Fluoxetine appears to be a safe and effective treatment in improving symptoms in, and the quality of life of, men with difficult CP/CPPS. Moreover, amelioration of difficult CP/CPPS-related symptoms could be related to a decrease in depressive symptoms.

    Diabetes mellitus is a common disease and its prevalenceis increasing worldwide. In various studiesup to 30%-70% of patients present dysfunction andcomplications related to the gut. To date several clinicalstudies have demonstrated that autonomic nervoussystem neuropathy and generalized neuropathy ofthe central nervous system (CNS) may play a majorrole. This systematic review provides an overviewof the neurodegenerative changes that occur as aconsequence of diabetes with a focus on the CNSchanges and gastrointestinal (GI) dysfunction. Animalmodels where diabetes was induced experimentallysupport that the disease induces changes in CNS.Recent investigations with electroencephalographyand functional brain imaging in patients with diabetesconfirm these structural and functional brain changes.Encephalographic studies demonstrated that alteredinsular processing of sensory stimuli seems to be akey player in symptom generation. In fact one studyindicated that the more GI symptoms the patientsexperienced, the deeper the insular electrical sourcewas located. The electroencephalography was oftenused in combination with quantitative sensory testing mainly showing hyposensitivity to stimulation of GIorgans. Imaging studies on patients with diabetes andGI symptoms mainly showed microstructural changes,especially in brain areas involved in visceral sensoryprocessing. As the electrophysiological and imagingchanges were associated with GI and autonomicsymptoms they may represent a future therapeutictarget for treating diabetics either pharmacologically orwith neuromodulation.

    Background: Cardiac complications associated with diabetes mellitus have become major cause of concern. Antidiabetic drugs, with varied mode of action, are although available, apprehensions exist for their limited action or side effects upon prolonged use. Efforts are therefore inclined toward finding other alternatives. The present study was, thus, undertaken to evaluate the cardioprotective effect of Azadirachta indica (AI) on microangiopathic changes in rat model of diabetes. Materials and Methods: Diabetes was induced in male rats by single intraperitoneal injection of streptozotocin (60 mg/kg body weight). Seven days after glucose levels are stabilized, aqueous leaf extract of AI (ALE) (600 mg/kg1 body weight) was administered orally to diabetic animals every day for 7 days. Results: High blood glucose characterizing diabetes in these animals was found to show increased lipid peroxidation (LPO), altered antioxidant biomarkers together with microangiopathic alterations. The treatment of diabetic rats with ALE reduced the levels of blood glucose, LPO, and restored the activities of antioxidant enzyme. Light and transmission electron microscopic analysis revealed reduced necrotic areas and inflammation in tissue architecture of ALE treated heart in comparison to untreated diabetic group. Conclusion: AI provides cardioprotection by ameliorating oxidative stress in rat model of diabetic mellitus. SUMMARY The streptozotocin (STZ) treatment (60 mg/kg body weight) to animals induced diabetic changes such as elevated blood glucose levels, decreased body weight, altered lipid profiles together with development of proxidant state evidenced by elevated levels of lipid peroxidation (LPO), depletion in reduced glutathione (GSH) levels and altered antioxidant enzymes with consequent microangiopathic alterations in heart tissue evinced by localization of necrotic and inflamed areas in heart tissueThe treatment of animals with Azadirachta indica leaf extract (ALE) (600 mg

    Objective: To investigate the possible ameliorative effect of crude water extract of Morus alba(M. alba) leaves on retinopathy of rat pups maternally subjected to diabetes and/or Al intoxication.Methods: Both control and experimental groups were subjected to certain integrated approaches, namely, biochemical assessments, light microscopic investigation, transmission electron microscopic investigation, single cell gel electrophoresis(comet assay) and determination of DNA fragmentation.Results: The retina of pups of diabetic and/or Al-intoxicated mothers exhibited abnormal alterations in retinal cell layers including retinal pigmented epithelium, photoreceptor inner segment and ganglion cells. Increased incidence of DNA fragmentation and apoptosis were evident in pups of diabetic and/or Al-intoxicated mothers. However, retina of pups maternally received M. alba extract plus diabetes or Al-intoxicated alone or in combination showed marked amelioration. Less degree of ameliorations was seen in retina of pups maternally subjected to combined treatment. Furthermore, application of crude water extract of M.alba resulted in amelioration of the alterations of maternal serum glucose as well as Al concentration.Conclusions: Based on the results of the present study, M. alba extract is effective against experimentally diabetic and Al-induced developmental retinopathy.

    The present study investigated the ability of melatonin in reducing metabolic risk factors and cardiac apoptosis induced by diabetes. Streptozotocin (60 mg/kg, i.p.) was injected into male rats, and after diabetic induction melatonin (10mg/kg i.g.) was administered orally for 21 days. Diabetic hearts showed increased number of apoptotic cells with downregulation of Bcl-2 and activation of p53 and CD95 as well as the caspases 9, 8 and 3. In addition, there was a significant decrease in insulin level, hyperglycemia, elevated HOMA-IR, glycosylated hemoglobin (HbA1c), total lipids, triglycerides, total cholesterol, low and very low-density lipoprotein and decreased high-density lipoprotein. These changes were coupled with a significant increase in the activities of creatin kinase-MB (CK-MB) and lactate dehydrogenase (LDH) in the serum of the diabetic rats indicating myocardium injury. Oral administration of melatonin for 3 weeks after diabetes induction ameliorated the levels of hyperglycemia, insulin, HbA1c, lipids profile and HOMA-IR. The oral melatonin treatment of diabetic rats significantly decreased the number of apoptotic cells in the heart compared to diabetic rats. It enhanced Bcl-2 expression and blocked the activation of CD95 as well as caspases 9, 8 and 3. These changes were accompanied with significant improvement of CK-MB and LDH in the serum indicating the ameliorative effect of melatonin on myocardium injury. Melatonin effectively ameliorated diabetic myocardium injury, apoptosis, reduced the metabolic risk factors and modulated important steps in both extrinsic and intrinsic pathways of apoptosis. Thus, melatonin may be a promising pharmacological agent for ameliorating potential cardiomyopathy associated with diabetes. PMID:25510232

    Full Text Available The present study was designed to probe the effects of Huperzine A (HupA on diabetes-associated cognitive decline (DACD using a streptozotocin (STZ-injected rat model. Diabetic rats were treated with HupA (0.05 and 0.1 mg/kg for seven weeks. Memory functions were evaluated by the water maze test. Nissl staining was selected for detecting neuronal loss. Protein and mRNA levels of brain-derived neurotrophic factor (BDNF were analyzed by ELISA and real-time PCR, respectively. The activities of choline acetylase (ChAT, Acetylcholinesterase (AChE, malondialdehyde (MDA, superoxide dismutase (SOD, glutathione peroxidase (GSH-Px, catalase (CAT, NF-κB p65 unit, TNF-α, IL-1β, IL-6 and caspase-3 were measured using corresponding kits. After seven weeks, diabetic rats exhibited remarkable reductions in: body weight, percentage of time spent in target quadrant, number of times crossing the platform, ChAT and BDNF levels, SOD, GSH-Px and CAT accompanied with increases in neuronal damage, plasma glucose levels, escape latency, mean path length, AChE, MDA level as well as CAT, NF-κB p65 unit, TNF-α, IL-1β, IL-6 and caspase-3 in cerebral cortex and hippocampus. Supplementation with HupA significantly and dose-dependently reversed the corresponding values in diabetes. It is concluded that HupA ameliorates DACD via modulating BDNF, oxidative stress, inflammation and apoptosis.

    Full Text Available Endothelial dysfunction is associated with diabetes mellitus and hypertension. Oxidative stress and augmented activity of associated enzymes like cyclooxygenase (COX and xanthine oxidase (XO is a major culprit. In this study, diabetes mellitus (DM was induced by alloxan (75 mg/kg, i.v and hypertension was induced by left renal artery (LRA ligation in male Wistar rats. Treatment with COX inhibitors, etoricoxib (10 mg/kg, p.o, lornoxicam (4.5 mg/kg, i.p and XO inhibitor, allopurinol (50 mg/kg, p.o was initiated after confirming induction of diabetes and hypertension and continued for 6 weeks. Vascular reactivity to catecholamines like adrenaline (1 µg/kg, noradrenaline (1 µg/kg, and phenylephrine (1 µg/kg, was evaluated in both models wherein treated rats expressed better responses than untreated groups. In an in vitro study, relaxant response to acetylcholine (ACh and sodium nitroprusside (SNP was observed on isolated aortas. Relaxation to ACh was impaired in untreated groups but treated groups produced near to normal relaxant responses. In case of SNP, no significant results were obtained. Diabetes and hypertension induced significant oxidative stress reflected by increase in lipid peroxidation level and decrease in antioxidant enzymes like catalase and superoxide dismutase. Drugs treatment reversed these effects on oxidative stress indices and ameliorated endothelial dysfunction.

    Full Text Available Diabetic peripheral neuropathy is a common complication of long-standing diabetes mellitus. To mimic clinical trials in which patients with diabetes enrolled have advanced peripheral neuropathy, we investigated the effect of sildenafil, a specific inhibitor of phosphodiesterase type 5 enzyme, on long term peripheral neuropathy in middle aged male mice with type II diabetes. Treatment of diabetic mice (BKS.Cg-m+/+Leprdb/J, db/db at age 36 weeks with sildenafil significantly increased functional blood vessels and regional blood flow in the sciatic nerve, concurrently with augmentation of intra-epidermal nerve fiber density in the skin and myelinated axons in the sciatic nerve. Functional analysis showed that the sildenafil treatment considerably improved motor and sensory conduction velocities in the sciatic nerve and peripheral thermal stimulus sensitivity compared with the saline treatment. In vitro studies showed that mouse dermal endothelial cells (MDE cultured under high glucose levels exhibited significant down regulation of angiopoietin 1 (Ang1 expression and reduction of capillary-like tube formation, which were completely reversed by sildenafil. In addition, incubation of dorsal root ganglia (DRG neurons with conditioned medium harvested from MDE under high glucose levels suppressed neurite outgrowth, where as conditional medium harvested from MDE treated with sildenafil under high glucose levels did not inhibit neurite outgrowth of DRG neurons. Moreover, blockage of the Ang1 receptor, Tie2, with a neutralized antibody against Tie2 abolished the beneficial effect of sildenafil on tube formation and neurite outgrowth. Collectively, our data indicate that sildenafil has a therapeutic effect on long term peripheral neuropathy of middle aged diabetic mice and that improvement of neurovascular dysfunction by sildenafil likely contributes to the amelioration of nerve function. The Ang1/Tie2 signaling pathway may play an important role in these

    .038, diaphragm (p = 0.042, and heart muscles (p < 0.001. We show that the amelioration of symptoms was proportional to the extent of receptor depletion and that improvements were observed following administration of two P2RX7 antagonists (CK, p = 0.030 and p = 0.050 without any detectable side effects. However, approaches successful in animal models still need to be proved effective in clinical practice.These results are, to our knowledge, the first to establish that a single treatment can improve muscle function both short and long term and also correct cognitive impairment and bone loss in DMD model mice. The wide-ranging improvements reflect the convergence of P2RX7 ablation on multiple disease mechanisms affecting skeletal and cardiac muscles, inflammatory cells, brain, and bone. Given the impact of P2RX7 blockade in the DMD mouse model, this receptor is an attractive target for translational research: existing drugs with established safety records could potentially be repurposed for treatment of this lethal disease.

    Little is known about the protective effects of carvacrol on the symptoms of streptozotocin induced diabetes in rats. Hence, this present study was designed to evaluate the protective effect of the strong antioxidant, carvacrol, on the symptoms of streptozotocin induced diabetes in rats. Carvacrol at the doses of 25 and 50 mg/kg body weight were orally administered to diabetic rats for a period of 7 days after the onset of diabetes. Food-water intake and body weight changes were daily recorded. Biochemical parameters such as serum glucose, insulin, total cholesterol, alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase were measured. Although treatment of diabetic rats with oral administration of carvacrol resulted in a slight reduction in serum glucose level and significant reduction in serum total cholesterol, alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase in comparison with diabetic control rats, there were no significant differences in serum insulin levels, food-water intake values and body weight changes. Despite the inadequacy of carvacrol on diabetes treatments, it was determined to have at least a partially protective role on liver enzymes. PMID:23579248

    Diabetes is one of the most prevalent chronic non-communicable diseases and is characterized by hyperglycemia and increased oxidative stress. These two alterations are also responsible for the main diabetic complications: cardiovascular disease, retinopathy, nephropathy and peripheral neuropathy. Diabetes progression is governed by pancreatic β-cell failure, and recent studies showed that sulforaphane (SFN) might be able to prevent this change, preserving insulin production. Consequently, our goal was to test the effects of SFN on metabolic parameters related to diabetic complications and antioxidant defenses (superoxide dismutase, catalase and sulfhydryl groups) in the pancreas, liver and kidney of non-diabetic and diabetic rats. Male Wistar rats were treated with water or 0.5 mg kg(-1) SFN i.p. for 21 days after diabetes induction. In diabetic animals treated with SFN, the serum levels of total cholesterol, non-HDL cholesterol and triacylglycerols were similar to those of non-diabetic animals, and the insulin responsiveness was higher than that of the diabetic animals that did not receive the compound. No effect of SFN on the superoxide dismutase and catalase activity or sulfhydryl groups was observed in the pancreas, liver or kidney of the treated animals. We conclude that SFN ameliorates some features of clinical diabetic complications particularly the lipid profile and insulin responsiveness, but it does not modulate the antioxidant response induced by superoxide dismutase, catalase and sulfhydryl groups in the evaluated organs.

    Efficacy of Kalpaamruthaa on the activities of lipid and carbohydrate metabolic enzymes, electron transport chain complexes and mitochondrial ATPases were studied in heart and liver of experimental rats. Cardiovascular damage (CVD) was developed in 8 weeks after type 2 diabetes mellitus induction with high fat diet (2 weeks) and low dose of streptozotocin (2 × 35 mg/kg b.w. i.p. in 24 hr interval). In CVD-induced rats, the activities of total lipase, cholesterol ester hydrolase and cholesterol ester synthetase were increased, while lipoprotein lipase and lecithin-cholesterol acyltransferase activities were decreased. The activities of lipid-metabolizing enzymes were altered by Kalpaamruthaa in CVD-induced rats towards normal. Kalpaamruthaa modulated the activities of glycolytic enzymes (hexokinase, phosphogluco-isomerase, aldolase and glucose-6-phosphate dehydrogenase), gluconeogenic enzymes (glucose-6-phosphatase and fructose-1, 6-bisphosphatase) and glycogenolytic enzyme (glycogen phosphorylase) along with increased glycogen content in the liver of CVD-induced rats. The activities of isocitrate dehydrogenase, succinate dehydrogenase, malate dehydrogenase, α-ketoglutarate dehydrogenase, Complexes and ATPases (Na(+)/K(+)-ATPase, Ca(2+)-ATPase and Mg(2+)-ATPase) were decreased in CVD-induced rats, which were ameliorated by the treatment with Kalpaamruthaa. This study ascertained the efficacy of Kalpaamruthaa for the treatment of CVD in diabetes through the modulation of metabolizing enzymes and mitochondrial dysfunction.

    Medicinal plants attract growing interest in the therapeutic management of Diabetes mellitus. Moringa oleifera is a remarkably nutritious vegetable with several antioxidant properties. The present study assessed the possible antioxidant and antidiabetic effects of an aqueous extract of M. oleifera leaves in treating streptozotocin-induced diabetic albino rats. The antidiabetic effects of aqueous extract of M. oleifera leaves were assessed histomorphometrically, ultrastructurally and biochemically. Fasting plasma glucose (FPG) was monitored and morphometric measurements of β-cells of islets of Langerhans (modified Gomori's stain) and collagen fibers (Mallory's trichrome stain) were performed. The antioxidant effects of M. oleifera leaves were determined by measuring the reduced glutathione and lipid peroxidation product, malondialdehyde, in pancreatic tissue. M. oleifera treatment significantly ameliorated the altered FPG (from 380% to 145%), reduced glutathione (from 22% to 73%) and malondialdehyde (from 385% to 186%) compared to control levels. The histopathological damage of islet cells was also markedly reversed. Morphometrically, M. oleifera significantly increased the areas of positive purple modified Gomori stained β-cells (from 60% to 91%) and decreased the area percentage of collagen fibers (from 199% to 120%) compared to control values. Experimental findings clearly indicate the potential benefits of using the aqueous extract of M. oleifera leaves as a potent antidiabetic treatment.

    DIA-2 is a herbal mixture containing standardized extract of Allium sativum and Lagerstroemia speciosa. Recently we have reported the anti-diabetic effect of DIA-2 in high fat diet (HFD) and streptozotocin (STZ) induced type 2 diabetic (T2D) rats. The purpose of this study was to investigate and compare the effects of DIA-2 with Rosiglitazone (RG) on plasma biomarkers of hepatocellular injury, liver carbohydrate metabolizing enzymes, glycogen content, oxidant/antioxidant status and histopathological changes in T2D rats. ALT and ALP levels were significantly decreased after DIA-2 and RG treatment compared to T2D rats. Total protein and albumin remained unaltered in all the groups. Significant decrease in AST levels were observed after DIA-2 (125 mg/kg) and RG treatment. Hepatic hexokinase activity was significantly increased after RG and DIA-2 treatment and fructose-1, 6-bisphosphatase activity were inversely correlated with hexokinase activity. Hepatic gucose-6-phosphatase activity was significantly (p < 0.05) reduced after DIA-2 (62.5 mg/kg) and RG treatment. Lipid peroxides levels was significantly decreased in the liver of DIA-2 (62.5; p < 0.01 & 125 mg/kg; p < 0.05) treated animals. Hepatic glycogen content (p < 0.05) and antioxidant enzymes [SOD (p < 0.01; 62.5 mg/kg); GPx and GSH (125 mg/kg; p < 0.01)] were significantly increased after DIA-2 treatment. RG treatment on hepatic glycogen, GPx (p < 0.01) and SOD, GSH (p < 0.05) levels were significant when compared to T2D rats. These biochemical parameters were also correlated with histopathological evaluation. The above findings revealed that administration of DIA-2 could ameliorate the biochemical and histopathological changes in liver of T2D rats indicating the protective role of DIA-2 against HFD/STZ induced diabetes. In addition, DIA-2 and RG treatment resulted in amelioration of hepatic steatosis in T2D rats. PMID:26367735

    Nicotinamide adenine dinucleotide phosphate (NADPH) oxidases are the main enzymes that produce oxidative stress, which plays an important role in painful diabetic neuropathy. Curcumin has been reported to exert an antinociceptive effect in a rat model of diabetic neuropathy by suppressing oxidative stress in the spinal cord. However, it remains unknown whether the mechanism by which curcumin ameliorates diabetic neuropathy can be attributed to spinal NADPH oxidases. This study was designed to determine the effect of curcumin on diabetic neuropathy and to investigate its precise mechanism in relation to NADPH oxidase-mediating oxidative stress in the spinal cord. Diabetic neuropathy was induced in Sprague-Dawley rats by intraperitoneal injection with 1% streptozotocin (STZ; 60 mg/kg). After the onset of diabetic neuropathy, a subset of the diabetic rats received daily intragastric administrations of curcumin (200mg/kg) or intraperitoneal injections of apocynin (2.5mg/kg) for 14 consecutive days, whereas other diabetic rats received equivalent volumes of normal saline (NS). STZ resulted in diabetic neuropathy with hyperglycemia and a lower paw withdrawal threshold (PWT), accompanied by elevations in the expression of the NADPH oxidase subunits p47(phox) and gp91(phox) and in the levels of hydrogen peroxide (H2O2) and malondialdehyde (MDA) and a reduction in superoxide dismutase (SOD) activity (Pdiabetic neuropathy. In conclusion, curcumin attenuated neuropathic pain in diabetic rats, at least partly by inhibiting NADPH oxidase-mediating oxidative stress in the spinal cord.

    Full Text Available Abstract Background Alpha-lipoic acid (ALA, a naturally occurring compound, exerts powerful protective effects in various cardiovascular disease models. However, its role in protecting against diabetic cardiomyopathy (DCM has not been elucidated. In this study, we have investigated the effects of ALA on cardiac dysfunction, mitochondrial oxidative stress (MOS, extracellular matrix (ECM remodeling and interrelated signaling pathways in a diabetic rat model. Methods Diabetes was induced in rats by I.V. injection of streptozotocin (STZ at 45 mg/kg. The animals were randomly divided into 4 groups: normal groups with or without ALA treatment, and diabetes groups with or without ALA treatment. All studies were carried out 11 weeks after induction of diabetes. Cardiac catheterization was performed to evaluate cardiac function. Mitochondrial oxidative biochemical parameters were measured by spectophotometeric assays. Extracellular matrix content (total collagen, type I and III collagen was assessed by staining with Sirius Red. Gelatinolytic activity of Pro- and active matrix metalloproteinase-2 (MMP-2 levels were analyzed by a zymogram. Cardiac fibroblasts differentiation to myofibroblasts was evaluated by Western blot measuring smooth muscle actin (α-SMA and transforming growth factor–β (TGF-β. Key components of underlying signaling pathways including the phosphorylation of c-Jun N-terminal kinase (JNK, p38 MAPK and ERK were also assayed by Western blot. Results DCM was successfully induced by the injection of STZ as evidenced by abnormal heart mass and cardiac function, as well as the imbalance of ECM homeostasis. After administration of ALA, left ventricular dysfunction greatly improved; interstitial fibrosis also notably ameliorated indicated by decreased collagen deposition, ECM synthesis as well as enhanced ECM degradation. To further assess the underlying mechanism of improved DCM by ALA, redox status and cardiac remodeling associated

    Epidemiological studies have demonstrated that diabetes mellitus is a serious health burden for both governments and healthcare providers. This study was hypothesized to evaluate the antihyperglycemic potential of eugenol by determine the activities of key enzymes of glucose metabolism in streptozotocin (STZ)-induced diabetic rats. Diabetes was induced into male albino Wistar rats by intraperitoneal administration of STZ (40 mg/kg body weight (b.w.)). Eugenol was administered to diabetic rats intragastrically at 2.5, 5, and 10 mg/kg b.w. for 30 days. The dose 10 mg/kg b.w. significantly reduced the levels of blood glucose and glycosylated hemoglobin (HbA1c) and increased plasma insulin level. The altered activities of the key enzymes of carbohydrate metabolism such as hexokinase, pyruvate kinase, glucose-6-phosphate dehydrogenase, glucose-6-phosphatase, fructose-1,6-bisphosphatase, and liver marker enzymes (AST, ALT, and ALP), creatine kinase and blood urea nitrogen in serum and blood of diabetic rats were significantly reverted to near normal levels by the administration of eugenol. Further, eugenol administration to diabetic rats improved body weight and hepatic glycogen content demonstrated the antihyperglycemic potential of eugenol in diabetic rats. The present findings suggest that eugenol can potentially ameliorate key enzymes of glucose metabolism in experimental diabetes, and it is sensible to broaden the scale of use of eugenol in a trial to alleviate the adverse effects of diabetes.

    It is not known how discrimination might affect diabetes-related distress (DRD), an important correlate of diabetes outcomes. We examined correlates of discrimination and the influence of discrimination on DRD and depressive symptoms (DS) for African Americans and Latinos with type 2 diabetes. We analyzed survey data (n = 157) collected at enrollment into a diabetes management intervention. Using multiple linear regression, we examined correlates of discrimination and the association between discrimination and DRD and DS. Discrimination was significantly associated with higher DRD for Latinos (b 1.58, 95% CI 1.08, 2.31, p < 0.05), but not significant for African Americans (b 0.96, 95% CI 0.59, 1.57). Discrimination was marginally significantly associated with more DS for Latinos (b 1.43, 95% CI 0.97, 2.12, p < 0.10), but not significant for African Americans (b 1.21, 95% CI 0.87, 1.70). These findings suggest the need to address stressors unique to racial/ethnic minorities to improve diabetes-related outcomes. PMID:23689972

    Background Berberine is one of the main constituents of Coptidis rhizoma (CR) and Cortex phellodendri, In this study, we investigated the beneficial effects of berberine on renal function and its possible mechanisms in rats with diabetic nephropathy(DN). Methods Male Wistar rats were divided into three groups: normal, diabetic model, and berberine treatment groups. Rats in the diabetic model and berberine treatment groups were induced to diabetes by intraperitonal injection with streptozotocin(STZ). Glomerular area, glomerular volume, fasting blood glucose(FBG), blood urea nitrogen(BUN), serum creatinine (Cr)and urine protein for 24 hours(UP24h) were measured using commercially available kits. Meanwhile, the activity of superoxide dismutase (SOD), content of malondialdehyde (MDA) in serum, activity of aldose reductase (AR)and the expression of AR mRNA and protein in kidney were detected by different methods. Results The result showed that oral administration of berberine (200mg·kg-1·d-1) significantly ameliorated the ratio of kidney weight to body weight. Glomerular area, glomerular volume, FBG, BUN, Cr and UP24h were significantly decreased in the berberine treatment group compared with the diabetic model group(P<0.05). Berberine treatment significantly increased serum SOD activity and decreased the content of MDA compared with diabetic model group(P<0.05). AR activity as well as the expression of AR mRNA and protein in the kidney was markedly decreased in the berberine treatment group compared with diabetic model group (P<0.05). Conclusion These results suggested that berberine could ameliorate renal dysfunction in DN rats through controlling blood glucose, reduction of oxidative stress and inhibition of the activation of the polyol pathway.

    Full Text Available Background. Although pathological involvements of diabetic polyneuropathy (DPN have been reported, no dependable treatment of DPN has been achieved. Recent studies have shown that mesenchymal stem cells (MSCs ameliorate DPN. Here we demonstrate a differentiation of induced pluripotent stem cells (iPSCs into MSC-like cells and investigate the therapeutic potential of the MSC-like cell transplantation on DPN. Research Design and Methods. For induction into MSC-like cells, GFP-expressing iPSCs were cultured with retinoic acid, followed by adherent culture for 4 months. The MSC-like cells, characterized with flow cytometry and RT-PCR analyses, were transplanted into muscles of streptozotocin-diabetic mice. Three weeks after the transplantation, neurophysiological functions were evaluated. Results. The MSC-like cells expressed MSC markers and angiogenic/neurotrophic factors. The transplanted cells resided in hindlimb muscles and peripheral nerves, and some transplanted cells expressed S100β in the nerves. Impairments of current perception thresholds, nerve conduction velocities, and plantar skin blood flow in the diabetic mice were ameliorated in limbs with the transplanted cells. The capillary number-to-muscle fiber ratios were increased in transplanted hindlimbs of diabetic mice. Conclusions. These results suggest that MSC-like cell transplantation might have therapeutic effects on DPN through secreting angiogenic/neurotrophic factors and differentiation to Schwann cell-like cells.

    Aim: To search the peroxisome proliferator-activated receptor γ (PPARγ) agonists from Swietenia mahagony extract (SmE) and observe the possible ameliorative effects of SmE on diabetic db/db mice. Methods: The PPARγ agonistic activity of SmE was screened by yeast-two hybrid system. The blood glucose levels of diabetic db/db mice were measured using a blood glucose level monitor and the data were statistically analyzed by NDST8.8W software. Results: By using the clinical drug rosiglitazone as a positive control, it was found that the PPARγ agonistic activity of SmE at a concentration of 50 μg/L was approximately half that of 35.7 μg/L (0.1 μmol/L) of rosiglitazone. At the dose of 1000 mg/kg, SmE remark ably decreased the blood glucose concentration of db/db mice from (15.26±2.98) to (7.58±2.20) mmol/L, and reduced the blood glucose levels by 55.49% compared with the control group (P<0.01). Conclusion: SmE shows agonistic activity to PPARγ and can ameliorate the blood glucose levels of diabetic db/db mice. SmE may be thus used as a potential agent for diabetes therapy.

    The therapeutic potential and molecular mechanism of phycocyanin from Spirulina on alloxan-induced diabetes mice was investigated. In the experiment, 4-week treatment of phycocyanin at the dose of 100 and 200 mg/kg body weight in alloxan-induced diabetes mice resulted in improved metrics in comparison with alloxan-induced diabetes group. These metrics include blood glucose levels, glycosylated serum protein (GSP), glycosylated hemoglobin (GHb) and fasting serum insulin (FINS) levels. As its molecular mode of action, phycocyanin leads to the increase of IRS-1 tyrosine phosphorylation and the decrease of IRS-1 serine phosphorylation, also accompany with increased level of Akt phosphorylation on Ser473 in the liver and pancreas in diabetic mice. In addition, phycocyanin treatment enhanced the glucokinase (GK) level in the liver and pancreas, and the glucokinase regulatory protein (GKRP) level in the liver in diabetic mice. The results suggest that phycocyanin ameliorates alloxan-induced diabetes mellitus in mice by activating insulin signaling pathway and GK expression in pancreas and liver in diabetic mice.

    Self-reported stroke symptoms may represent unrecognized cerebrovascular events leading to poorer cognitive and mental health. We examined relationships between stroke symptoms, cognitive impairment, and depressive symptoms in a high-risk sample: 247 adults aged ≥65 with diabetes. Stroke symptoms were assessed using the Questionnaire for Verifying Stroke-free Status, cognitive impairment was measured with the modified Telephone Interview for Cognitive Status, and depressive symptoms were measured using the 15-item Geriatric Depression Scale. In 206 participants without history of stroke/transient ischemic attack, 27.7% reported stroke symptoms, with sudden loss of comprehension most frequently reported (11.7%). Having >1 versus 0 stroke symptoms was associated with greater odds of cognitive impairment (odds ratio = 3.04, 95% confidence interval 1.15-8.05) and more depressive symptoms (b= 2.60,Pdiabetes duration, diabetes severity, and cardiovascular comorbidities. Better recognition and treatment of cerebrovascular problems in older adults with diabetes may lead to improved cognition and mental health. PMID:26801916

    Obstructive sleep apnea (OSA) is associated with insulin resistance, glucose intolerance, and type 2 diabetes. Causal mechanisms mediating this association are not well defined; however, augmented lipolysis in adipose might be involved. Here, we investigated the effect of acipimox treatment (lipolysis inhibitor) on glucose tolerance and insulin sensitivity in mice exposed to intermittent hypoxia (IH). C57BL6/J mice were exposed for 14 days to IH or control conditions. IH was created by decreasing the fraction of inspired oxygen from 20.9 to 6.5%, 60 times/h. Control exposure was air (fraction of inspired oxygen, 20.9%) delivered at an identical flow rate. Acipimox was provided in drinking water (0.5 g/ml) during exposures. After exposures, intraperitoneal insulin (0.5 IU/kg) and glucose (1 g/kg) tolerance tests were performed, and primary adipocytes were isolated for lipolysis experiments. IH elevated fasting glucose by 51% and worsened glucose tolerance and insulin sensitivity by 33 and 102%, respectively. In parallel, IH increased spontaneous lipolysis by 264%, and reduced epididymal fat mass by 15% and adipocyte size by 8%. Acipimox treatment prevented IH-induced lipolysis and increased epididymal fat mass and adipocyte size by 19 and 10%, respectively. Acipimox fully prevented IH-induced impairments in fasting glycemia, glucose tolerance, and insulin sensitivity. For all reported results, P less than 0.05 was considered significant. Augmented lipolysis contributes to insulin resistance and glucose intolerance observed in mice exposed to IH. Acipimox treatment ameliorated the metabolic consequences of IH and might represent a novel treatment option for patients with obstructive sleep apnea. PMID:26978122

    Full Text Available Abstract Background Chronic inflammation plays an important role in the progression of diabetic nephropathy (DN and that the infiltration of macrophages in glomerulus has been implicated in the development of glomerular injury. We hypothesized that the plant polyphenolic compound curcumin, which is known to exert potent anti-inflammatory effect, would ameliorate macrophage infiltration in streptozotocin (STZ-induced diabetic rats. Methods Diabetes was induced with STZ (55 mg/kg by intraperitoneal injection in rats. Three weeks after STZ injection, rats were divided into three groups, namely, control, diabetic, and diabetic treated with curcumin at 100 mg/kg/day, p.o., for 8 weeks. The rats were sacrificed 11 weeks after induction of diabetes. The excised kidney was used to assess macrophage infiltration and expression of various inflammatory markers. Results At 11 weeks after STZ injection, diabetic rats exhibited renal dysfunction, as evidenced by reduced creatinine clearance, increased blood glucose, blood urea nitrogen and proteinuria, along with marked reduction in the body weight. All of these abnormalities were significantly reversed by curcumin. Hyperglycemia induced the degradation of IκBα and NF-κB activation and as a result increased infiltration of macrophages (52% as well as increased proinflammatory cytokines: TNF-α and IL-1β. Curcumin treatment significantly reduced macrophage infiltration in the kidneys of diabetic rats, suppressed the expression of above proinflammatory cytokines and degradation of IκBα. In addition, curcumin treatment also markedly decreased ICAM-1, MCP-1 and TGF-β1 protein expression. Moreover, at nuclear level curcumin inhibited the NF-κB activity. Conclusion Our results suggested that curcumin treatment protect against the development of DN in rats by reducing macrophage infiltration through the inhibition of NF-κB activation in STZ-induced diabetic rats.

  9. Ameliorating role of chromium ingestion on biochemical, histological and trigluconate disorders induced by diabetes and / or gamma irradiation in pregnant albino rats and their fetuses

    International Nuclear Information System (INIS)

    Chromium is an essential trace element in human nutrition for the regulation of insulin action thereby influencing carbohydrate and lipid metabolism The aim of the present study was to evaluate the role of chromium intake on radiation-induced damage in diabetic mothers. Diabetes was induced in female rats by intraperitoneal injection of 150 mg/kg alloxan dissolved in saline. Pregnant diabetic mothers were received chromium (20 mg/kg) from the 1st up to the 19 th day of gestation. Meanwhile, pregnant diabetic rats were exposed to 0.3 Gy gamma radiation on the 6th and the 12 th day of gestation. Chromium treatment of diabetic mothers ameliorated radiation-induced damage, which was obvious by diminishing the increase of glucose, malonaldehyde (MDA), total cholesterol levels and by ameliorating the decrease of glutathione level in blood serum. In addition,chromium treatment ameliorated the radiation-induced changes in cholesterol levels of the fetuses. Moreover, chromium treatment led to the regeneration of the normal architecture of maternal hepatic cells and blood vessels. It could be concluded that chromium supplementation to diabetic mothers ameliorated the radiation-induced biochemical, histopathological and teratological disorders. Furthermore, the results obtained showed that chromium administration caused a significant protection to diabetic pregnant females against radiation-induced spontaneous abortion and embryo malformations

    Although erythropoietin ameliorates experimental type 2 diabetes with neuropathy, serious side effects limit its potential clinical use. ARA 290, a nonhematopoietic peptide designed from the structure of erythropoietin, interacts selectively with the innate repair receptor that mediates tissue protection. ARA 290 has shown efficacy in preclinical and clinical studies of metabolic control and neuropathy. To evaluate the potential activity of ARA 290 in type 2 diabetes and painful neuropathy, subjects were enrolled in this phase 2 study. ARA 290 (4 mg) or placebo were self-administered subcutaneously daily for 28 d and the subjects followed for an additional month without further treatment. No potential safety issues were identified. Subjects receiving ARA 290 exhibited an improvement in hemoglobin A1c (Hb A1c) and lipid profiles throughout the 56 d observation period. Neuropathic symptoms as assessed by the PainDetect questionnaire improved significantly in the ARA 290 group. Mean corneal nerve fiber density (CNFD) was reduced significantly compared with normal controls and subjects with a mean CNFD >1 standard deviation from normal showed a significant increase in CNFD compared with no change in the placebo group. These observations suggest that ARA 290 may benefit both metabolic control and neuropathy in subjects with type 2 diabetes and deserves continued clinical evaluation. PMID:25387363

    Full Text Available The tuberous root of Liriope spicata var. prolifera (TRLS; Liliaceae family is valued for the ability to promote glucose homeostasis, and it may therefore be utilized as an adjuvant therapy in the control of diabetic complications. The aim of the present study was to examine the effects of an aqueous ethanol extract from TRLS (TRLS-ext (100 or 200 mg kg−1 per day for eight weeks on rats with streptozotocin-induced diabetic nephropathy (DN. Renal dysfunction in diabetic rats was ameliorated by TRLS-ext as evidenced by reduced creatinine clearance, as well as increased blood urea nitrogen and proteinuria. Treatment with TRLS-ext was found to markedly improve histological architecture in the diabetic kidney. Hyperglycemia induced degradation of inhibitory kappa B and reduced nuclear factor kappa B activation, leading to increased infiltration of macrophages and increased levels of proinflammatory cytokines, including interleukin-1 and tumor necrosis factor-α. All of the above abnormalities were reversed by TRLS-ext treatment, which also decreased the expression of intercellular adhesion molecule-1, monocyte chemoattractant protein-1, and fibronectin in the diabetic kidneys. These findings provide a perspective on the renoprotective effects of TRLS-ext in DN.

    In this study, we identified a strain of lactic acid bacteria (LAB) that induces high levels of IL-10 production by immune cells, and evaluated the ability of the strain to suppress chronic inflammation and ameliorate metabolic disorders in in vitro and in vivo models. Among a collection of LAB strains, Lactobacillus plantarum strain OLL2712 (OLL2712) induced the highest levels of IL-10 production in mouse-derived dendritic cells and peritoneal macrophages. The anti-inflammatory effects of this strain were evaluated using a co-culture system comprising RAW 264.7 and 3T3-L1 cells. We also administered heat-killed OLL2712 to obese and type 2 diabetic KKAy mice for 3 wk to evaluate the in vivo effects of the strain. The OLL2712 significantly decreased the production of proinflammatory cytokines in vitro. Likewise, the administration of OLL2712 significantly suppressed proinflammatory cytokine levels in both the visceral adipose tissue and the serum of KKAy mice, and reduced serum triglyceride concentrations. The strain also alleviated oxidative stress and adrenaline levels in the serum of KKAy mice. On the other hand, Lactobacillus gasseri strain MEP222804 (a moderate IL-10 inducer) did not ameliorate the systemic inflammation and hyperlipidemia in KKAy mice. Our results suggest that treatment with strong IL-10-inducing LAB has the potential to ameliorate metabolic disorders by suppressing chronic inflammation in the host animal.

  14. Insulin-Producing Cells Differentiated from Human Bone Marrow Mesenchymal Stem Cells In Vitro Ameliorate Streptozotocin-Induced Diabetic Hyperglycemia.

    Full Text Available The two major obstacles in the successful transplantation of islets for diabetes treatment are inadequate supply of insulin-producing tissue and immune rejection. Induction of the differentiation of human bone marrow-derived mesenchymal stem cells (hMSCs into insulin-producing cells (IPCs for autologous transplantation may alleviate those limitations.hMSCs were isolated and induced to differentiate into IPCs through a three-stage differentiation protocol in a defined media with high glucose, nicotinamide, and exendin-4. The physiological characteristics and functions of IPCs were then evaluated. Next, about 3 × 10(6 differentiated cells were transplanted into the renal sub-capsular space of streptozotocin (STZ-induced diabetic nude mice. Graft survival and function were assessed by immunohistochemistry, TUNEL staining and measurements of blood glucose levels in the mice.The differentiated IPCs were characterized by Dithizone (DTZ positive staining, expression of pancreatic β-cell markers, and human insulin secretion in response to glucose stimulation. Moreover, 43% of the IPCs showed L-type Ca2+ channel activity and similar changes in intracellular Ca2+ in response to glucose stimulation as that seen in pancreatic β-cells in the process of glucose-stimulated insulin secretion. Transplantation of functional IPCs into the renal subcapsular space of STZ-induced diabetic nude mice ameliorated the hyperglycemia. Immunofluorescence staining revealed that transplanted IPCs sustainably expressed insulin, c-peptide, and PDX-1 without apparent apoptosis in vivo.IPCs derived from hMSCs in vitro can ameliorate STZ-induced diabetic hyperglycemia, which indicates that these hMSCs may be a promising approach to overcome the limitations of islet transplantation.

    Vascular endothelial dysfunction is regarded as the initial step of vascular complications in diabetes mellitus. This study investigated the amelioration of apigenin and naringenin in type 2 diabetic (T2D) rats induced by high-fat diet and streptozotocin and explored the underlying mechanism. Apigenin or naringenin was intragastrically administered at 50 or 100mg/kg once a day for 6 weeks. Biochemical parameters including blood glucose, glycated serum protein, serum lipid, insulin, superoxide dismutase (SOD), malonaldehyde and intercellular adhesion molecule-1 (ICAM-1) were measured. Vascular reactivity in isolated thoracic aortic rings was examined. Pathological features of the thoracic aorta were further observed through optical microscopy and transmission electron microscopy. Lastly, we evaluated their effects on insulin resistance of palmitic acid (PA)-induced endothelial cells. Compared with diabetic control group, apigenin and naringenin significantly decreased the levels of blood glucose, serum lipid, malonaldehyde, ICAM-1 and insulin resistance index, increased SOD activity and improved impaired glucose tolerance. Apigenin and naringenin restored phenylephrine-mediated contractions and acetylcholine or insulin-induced relaxations in aortic tissues. Furthermore, pathological damage in the thoracic aorta of apigenin and naringenin groups was more remissive than diabetic control group. In vitro, apigenin and naringenin inhibited NF-κB activation and ICAM-1 mRNA expression in PA-treated endothelial cells and improved nitric oxide production in the presence of insulin. In conclusion, both apigenin and naringenin can ameliorate glucose and lipid metabolism, as well as endothelial dysfunction in T2D rats at least in part by down-regulating oxidative stress and inflammation. In general, apigenin showed greater potency than naringenin equivalent. PMID:26801071

    Contrast medium-induced acute kidney injury (CI-AKI) remains a leading cause of iatrogenic, drug-induced acute renal failure. This study aimed to investigate the protective effects of atorvastatin against renal tubular cell apoptosis in diabetic rats and the related mechanisms. CI-AKI was induced by intravenous administration of iopromide (12ml/kg) in streptozotocin-induced diabetic rats. Atorvastatin (ATO) was administered intragastrically at the dose of 5, 10 and 30mg/kg/d in different groups, respectively, for 5 days before iopromide injection. Renal function parameters, kidney histology, renal tubular cell apoptosis, the expression of apoptosis regulatory proteins, caspase-3 and Rho-associated protein kinase 1 (ROCK-1), and the phosphorylation of myosin phosphatase target subunit -1 (MYPT-1), were determined. Atorvastatin was shown to notably ameliorate contrast medium induced medullary damage, restore renal function, and suppress renal tubular apoptosis. Meanwhile, atorvastatin up-regulated the expression of Bcl-2, down-regulated the expression of Bax, caspase-3 and ROCK-1, restored the ratio of Bcl-2/Bax, and suppressed the phosphorylation of MYPT-1 in a dose-dependent manner. Thus, atorvastatin pretreatment could dose-dependently ameliorate the development of CI-AKI, which was partly attributed to its suppression of renal tubular cell apoptosis by inhibiting the Rho/ROCK pathway.

    Among the diabetic complications, diabetic foot ulcer due to delayed wound healing is one of the most significant clinical problems. Early inflammatory stage is important for better prognosis during wound healing. Thus, regulation of inflammatory response during early stage of wound healing is main target for complete cutaneous recovery. This study investigated the role of genistein supplementation in inflammation and oxidative stress, which are related to NLRP3 inflammasome, NFκB and Nrf2 activation, during cutaneous wound healing in alloxan-induced diabetic mice. Mice with diabetes with fasting blood glucose (FBG) levels > 250 mg/dl were fed diets with AIN-93G rodent diet containing 0%, 0.025% (LG) or 0.1% (HG) genistein. After 2 weeks of genistein supplementation, excisional wounds were made by biopsy punches (4 mm). Genistein supplementation improved fasting glucose levels and wound closure rate. Moreover, genistein supplementation restored NLRP3 inflammasome (NLRP3, ASC and caspase-1) at the basal level and ameliorated both inflammation (TNFα, iNOS, COX2 and NFκB) and antioxidant defense system (Nrf2, HO-1, GPx, and catalase) during early stage of wound healing in diabetic mice. Taken together, genistein supplementation would be a potential therapeutic nutrient in prevention and treatment of delayed wound healing by modulation of inflammation and oxidative stress during inflammatory stage.

    The present study aims to study the possible renal protective effect of simvastatin in the development and progression of type 2 diabetic nephropathy. A rat model of T2DN was induced by high-fat diet together with single low-dose of streptozotocin. The diabetic rats were either given treatment or vehicle control for 13 weeks to develop nephropathy. At the end of treatment, parameters of renal function were determined. Kidney samples were collected for histological studies and generated homogenates for biochemical analysis. In T2DN rats, severe hyperglycemia was developed, FBG were markedly elevated. Diabetes induced significant alterations in renal structure, such as severe reduction of glomerular tufts, increase in Bowman's spaces, thickening of GBM. In addition, and SCr, UAER and BUN are elevated, accompanied with reduction in UCr and CCr, indicating obvious renal failure. On the other hand, endogenous antioxidants SOD, GSH-Px were reduced, whereas MDA was increased. However, treatment of T2DN rats with simvastatin restored renal changes in different aspects. Our results showed that STZ-induced T2DN could be attenuated by simvastatin. The renoprotective effects of simvastatin was indicated by improvements in kidney function parameters, and was attributed by its lipid-lowering effect as well as its anti-oxidative stress, anti-inflammatory properties without having noticeable influence on glycemic control. Simvastatin ameliorates low-dose Streptozotocin-induced type 2 diabetic nephropathy in an experimental rat model. PMID:26131264

    This study aimed to evaluate the hypoglycemic effect of Zanthoxylum alkylamides and explore the potential mechanism in streptozotocin (STZ)-induced diabetic rats. Diabetic rats were orally treated with 3, 6, and 9 mg per kg bw alkylamides daily for 28 days. As the alkylamide dose increased, the relative weights of the liver and kidney, fasting blood glucose, and fructosamine levels were significantly decreased. The alkylamides also significantly increased the body weight and improved the oral glucose tolerance of the rats. Likewise, the alkylamides significantly increased the levels of liver and muscle glycogen and plasma insulin. These substances further alleviated the histopathological changes in the pancreas of the diabetic rats. The beneficial effects of high-dose alkylamides showed a comparable activity to the anti-diabetic drug glibenclamide. Western blot and real-time PCR results revealed that the alkylamide treatment significantly decreased the expression levels of the key enzymes (phosphoenolpyruvate caboxykinase and glucose-6-phosphatase) involved in gluconeogenesis and increased the glycolysis enzyme (glucokinase) in the liver, and enhanced the expression levels of pancreatic duodenal homeobox-1, glucokinase, and glucose transporter 2 in the pancreas. In addition, it was also observed that the alkylamides, unlike glibenclamide, increased the transient receptor potential cation channel subfamily V member 1 and decreased cannabinoid receptor 1 expressions in the liver and pancreas. Therefore, alkylamides can prevent STZ-induced hyperglycemia by altering the expression levels of the genes related to glucose metabolism and by ameliorating pancreatic dysfunction.

    Insulin resistance is the primary characteristic of type 2 diabetes and results from insulin signaling defects. Cocoa has been shown to exert anti-diabetic effects by lowering glucose levels. However, the molecular mechanisms responsible for this preventive activity and whether cocoa exerts potential beneficial effects on the insulin signaling pathway in the liver remain largely unknown. Thus, in this study, the potential anti-diabetic properties of cocoa on glucose homeostasis and insulin signaling were evaluated in type 2 diabetic Zucker diabetic fatty (ZDF) rats. Male ZDF rats were fed a control or cocoa-rich diet (10%), and Zucker lean animals received the control diet. ZDF rats supplemented with cocoa (ZDF-Co) showed a significant decrease in body weight gain, glucose and insulin levels, as well as an improved glucose tolerance and insulin resistance. Cocoa-rich diet further ameliorated the hepatic insulin resistance by abolishing the increased serine-phosphorylated levels of the insulin receptor substrate 1 and preventing the inactivation of the glycogen synthase kinase 3/glycogen synthase pathway in the liver of cocoa-fed ZDF rats. The anti-hyperglycemic effect of cocoa appeared to be at least mediated through the decreased levels of hepatic phosphoenolpyruvate carboxykinase and increased values of glucokinase and glucose transporter 2 in the liver of ZDF-Co rats. Moreover, cocoa-rich diet suppressed c-Jun N-terminal kinase and p38 activation caused by insulin resistance. These findings suggest that cocoa has the potential to alleviate both hyperglycemia and hepatic insulin resistance in type 2 diabetic ZDF rats.

    Patients with type 1 diabetes mellitus are associated with impairment in vitamin A metabolism. This study evaluated whether treatment with retinoic acid, the biologically active metabolite of vitamin A, can ameliorate diabetes. All-trans retinoic acid (atRA) was used to treat streptozotocin (STZ)-induced diabetic mice which revealed atRA administration ameliorated blood glucose levels of diabetic mice. This hyperglycemic amelioration was accompanied by an increase in the amount of β cells co-expressed Pdx1 and insulin and by restoration of the vascular laminin expression. The atRA-induced production of vascular endothelial growth factor-A from the pancreatic islets was possibly the key factor that mediated the restoration of islet vascularity and recovery of β-cell mass. Furthermore, the combination of islet transplantation and atRA administration significantly rescued hyperglycemia in diabetic mice. These findings suggest that vitamin A derivatives can potentially be used as a supplementary treatment to improve diabetes management and glycemic control. PMID:27381866

    Full Text Available Sodium meta-arsenite (SA is implicated in the regulation of hepatic gluconeogenesis-related genes in vitro; however, the effects in vivo have not been studied. We investigated whether SA has antidiabetic effects in a type 2 diabetic mouse model. Diabetic db/db mice were orally intubated with SA (10 mg kg−1 body weight/day for 8 weeks. We examined hemoglobin A1c (HbA1c, blood glucose levels, food intake, and body weight. We performed glucose, insulin, and pyruvate tolerance tests and analyzed glucose production and the expression of gluconeogenesis-related genes in hepatocytes. We analyzed energy metabolism using a comprehensive animal metabolic monitoring system. SA-treated diabetic db/db mice had reduced concentrations of HbA1c and blood glucose levels. Exogenous glucose was quickly cleared in glucose tolerance tests. The mRNA expressions of genes for gluconeogenesis-related enzymes, glucose 6-phosphatase (G6Pase, and phosphoenolpyruvate carboxykinase (PEPCK were significantly reduced in the liver of SA-treated diabetic db/db mice. In primary hepatocytes, SA treatment decreased glucose production and the expression of G6Pase, PEPCK, and hepatocyte nuclear factor 4 alpha (HNF-4α mRNA. Small heterodimer partner (SHP mRNA expression was increased in hepatocytes dependent upon the SA concentration. The expression of Sirt1 mRNA and protein was reduced, and acetylated forkhead box protein O1 (FoxO1 was induced by SA treatment in hepatocytes. In addition, SA-treated diabetic db/db mice showed reduced energy expenditure. Oral intubation of SA ameliorates hyperglycemia in db/db mice by reducing hepatic gluconeogenesis through the decrease of Sirt1 expression and increase in acetylated FoxO1.

    Clinical research has confirmed the efficacy of several plant extracts in the modulation of oxidative stress associated with diabetes mellitus (DM). Oil of Eruca sativa seeds (ESS) is tried for prevention and treatment of DM induced experimentally by alloxan injection. A single dose of alloxan (100 mg/kg) produced a decrease in insulin level, hyperglycemia, elevated total lipids, triglycerides and cholesterol, decreased high-density lipoprotein and hepatic glycogen contents and elevated hepatic glucose-6-phosphatase activity. Concurrent with these changes, there was an increase in the concentration of malondialdehyde and 4-hydroxynonenal in the liver. This oxidative stress was related to a decreased glutathione (GSH) content and superoxide dismutase activity in the liver of alloxan-diabetic rats. ESS oil (0.06 ml/kg) on its own increased significantly hepatic GSH. Daily oral administration of ESS oil 2 weeks before or after diabetes induction ameliorated hyperglycemia, improved lipid profile, blunted the increase in malondialdehyde and 4-hydroxynonenal and stimulated the GSH production in the liver of alloxan-treated rats. We suggested that ESS oil could be used as antidiabetic complement in case of DM. This may be related to its antioxidative properties and to the increase in hepatic GSH.

  13. Dipeptidyl peptidase-4 inhibitor ameliorates early renal injury through its anti-inflammatory action in a rat model of type 1 diabetes

    International Nuclear Information System (INIS)

    Highlights: •DPP-4 inhibitor decreased urinary albumin excretion in a rat of type 1 diabetes. •DPP-4 inhibitor ameliorated histlogical changes of diabetic nephropathy. •DPP-4 inhibitor has reno-protective effects through anti-inflammatory action. •DPP-4 inhibitor is beneficial on diabetic nephropathy besides lowering blood glucose. -- Abstract: Introduction: Dipeptidyl peptidase-4 (DPP-4) inhibitors are incretin-based drugs in patients with type 2 diabetes. In our previous study, we showed that glucagon-like peptide-1 (GLP-1) receptor agonist has reno-protective effects through anti-inflammatory action. The mechanism of action of DPP-4 inhibitor is different from that of GLP-1 receptor agonists. It is not obvious whether DPP-4 inhibitor prevents the exacerbation of diabetic nephropathy through anti-inflammatory effects besides lowering blood glucose or not. The purpose of this study is to clarify the reno-protective effects of DPP-4 inhibitor through anti-inflammatory actions in the early diabetic nephropathy. Materials and methods: Five-week-old male Sprague–Dawley (SD) rats were divided into three groups; non-diabetes, diabetes and diabetes treated with DPP-4 inhibitor (PKF275-055; 3 mg/kg/day). PKF275-055 was administered orally for 8 weeks. Results: PKF275-055 increased the serum active GLP-1 concentration and the production of urinary cyclic AMP. PKF275-055 decreased urinary albumin excretion and ameliorated histological change of diabetic nephropathy. Macrophage infiltration was inhibited, and inflammatory molecules were down-regulated by PKF275-055 in the glomeruli. In addition, nuclear factor-κB (NF-κB) activity was suppressed in the kidney. Conclusions: These results indicate that DPP-4 inhibitor, PKF275-055, have reno-protective effects through anti-inflammatory action in the early stage of diabetic nephropathy. The endogenous biological active GLP-1 might be beneficial on diabetic nephropathy besides lowering blood glucose

    Full Text Available Lack of the physiological nocturnal fall in blood pressure (BP has been found in diabetics and it seems to be related to the presence of diabetic complications. The present study examined the changes in the nocturnal BP pattern of 8 normotensive insulin-dependent diabetic adolescents without nephropathy following improvement in glycemic control induced by an 8-day program of adequate diet and exercise. The same number of age- and sex-matched control subjects were studied. During the first and eighth nights of the program, BP was obtained by ambulatory BP monitoring. After a 10-min rest, 3 BP and heart rate (HR recordings were taken and the mean values were considered to represent their awake values. The monitor was programmed to cuff insufflation every 20 min from 10:00 p.m. to 7:00 a.m. The glycemic control of diabetics improved since glycemia (212.0 ± 91.5 to 140.2 ± 69.1 mg/dl, P<0.03, urine glucose (12.7 ± 11.8 to 8.6 ± 6.4 g/24 h, P = 0.08 and insulin dose (31.1 ± 7.7 to 16.1 ± 9.7 U/day, P<0.01 were reduced on the last day. The mean BP of control subjects markedly decreased during the sleeping hours of night 1 (92.3 ± 6.4 to 78.1 ± 5.0 mmHg, P<0.001 and night 8 (87.3 ± 6.7 to 76.9 ± 3.6 mmHg, P<0.001. Diabetic patients showed a slight decrease in mean BP during the first night. However, the fall in BP during the nocturnal period increased significantly on the eighth night. The average awake-sleep BP variation was significantly higher at the end of the study (4.2 vs 10.3%, P<0.05 and this ratio turned out to be similar to that found in the control group (10.3 vs 16.3%. HR variation also increased on the eighth night in the diabetics. Following the metabolic improvement obtained at the end of the period, the nocturnal BP variation of diabetics was close to the normal pattern. We suggest that amelioration of glycemic control may influence the awake-sleep BP and HR differences. This effect may be due at least in part to an attenuated

    Full Text Available Background: Satureja khuzestanica, an endemic plant of Iran, has been reported to be used traditionally to treat diabetes. We examined possible protective effect of Satureja khozestanica essential oil (SKE on glomerulosclerosis in alloxan-induced type 1 diabetic rats. Materials and Methods: In this experimental study, 30 Sprage-dawley male rats were divided into 3 groups randomly; group 1 as control, group 2 diabetic untreated, and group 3 treatments with SKE by 500 ppm in drinking water, respectively. Diabetes was induced in the second and third groups by alloxan injection subcutaneously. After 8 weeks, animals were anaesthetized; livers and kidneys were then removed immediately. Kidney paraffin sections were prepared and stained by periodic acid Schiff method. Glomerular volume and leukocyte infiltration were estimated by stereological rules and glomerular sclerosis was studied semi-quantitatively. Results: Flow treatment of diabetic animals with SKE could significantly inhibit glomerular hypertrophy (22% leukocyte infiltration (31% and glomerulosclerosis (20% in comparison with the diabetic untreated group. Conclusion: The findings showed that SKE alleviates loss of glomerular volume, leukocyte infiltration, and glomerulosclerosis and exerts beneficial effects on the lipid peroxidation in alloxan-induced type 1 diabetic rats.

    Full Text Available Background/Aims: In diabetic nephropathy (DN, the current angiotensin-II-blocking pharmacotherapy is frequently failing. For diabetic cardiomyopathy (DC, there is no specific remedy available. Relaxin-2 (Rlx - an anti-fibrotic, anti-inflammatory, and vasoprotecting peptide - is a candidate drug for both. Methods: Low-dose (32 µg/kg/day and high-dose (320 µg/kg/day Rlx were tested against vehicle (n = 20 each and non-diabetic controls (n = 14 for 12 weeks in a model of type-1 diabetes induced in endothelial nitric oxide synthase knock-out (eNOS-KO mice by intraperitoneal injection of streptozotocin. Results: Diabetic animals showed normal plasma creatinine, markedly increased albuminuria and urinary malonyldialdehyde, elevated relative kidney weight, glomerulosclerosis, and increased glomerular size, but no relevant interstitial fibrosis. Neither dose of Rlx affected these changes although the drug was active and targeted plasma levels were achieved. Of note, we found no activation of the renal TGF-β pathway in this model. In the hearts of diabetic animals, no fibrotic alterations indicative of DC could be determined which precluded testing of the initial hypothesis. Conclusions: We investigated a model showing early DN without overt tubulo-interstitial fibrosis and activation of the TGF-β-Smad-2/3 pathway. In this model, Rlx proved ineffective; however, the same may not apply to other models and types of diabetes.

    Diabetic cardiomyopathy (DCM) is a significant contributor to the morbidity and mortality associated with diabetes and metabolic syndrome. Retinoids, through activation of retinoic acid receptor (RAR) and retinoid x receptor (RXR), have been linked to control glucose and lipid homeostasis, with effects on obesity and diabetes. However, the functional role of RAR and RXR in the development of DCM remains unclear. Zucker diabetic fatty (ZDF) and lean rats were treated with Am580 (RARα agonist) or LGD1069 (RXR agonist) for 16 weeks, and cardiac function and metabolic alterations were determined. Hyperglycemia, hyperlipidemia and insulin resistance were observed in ZDF rats. Diabetic cardiomyopathy was characterized in ZDF rats by increased oxidative stress, apoptosis, fibrosis, inflammation, activation of MAP kinases and NF-κB signaling and diminished Akt phosphorylation, along with decreased glucose transport and increased cardiac lipid accumulation, and ultimately diastolic dysfunction. Am580 and LGD1069 attenuated diabetes-induced cardiac dysfunction and the pathological alterations, by improving glucose tolerance and insulin resistance; facilitating Akt activation and glucose utilization, and attenuating oxidative stress and interrelated MAP kinase and NF-κB signaling pathways. Am580 inhibited body weight gain, attenuated the increased cardiac fatty acid uptake, β-oxidation and lipid accumulation in the hearts of ZDF rats. However, LGD1069 promoted body weight gain, hyperlipidemia and cardiac lipid accumulation. In conclusion, our data suggest that activation of RAR and RXR may have therapeutic potential in the treatment of diabetic cardiomyopathy. However, further studies are necessary to clarify the role of RAR and RXR in the regulation of lipid metabolism and homeostasis.

    Zinc (Zn) is a component of numerous enzymes that function in a wide range of biological process, including growth, development, immunity and intermediary metabolism. Zn may play a role in chronic states such as cardiovascular disease and diabetes mellitus. Zn acts as cofactor and for many enzymes and proteins and has antioxidant, antiinflammatory and antiapoptotic effects. Taking into consideration that lung is a possible target organ for diabetic complications, the aim of this study was to investigate the protective role of zinc on the glycoprotein content and antioxidant enzyme activities of streptozotocin (STZ) induced diabetic rat tissues. Female Swiss albino rats were divided into four groups. Group I, control; Group II, control + zinc sulfate; Group III, STZ-diabetic; Group IV, diabetic + zinc sulfate. Diabetes was induced by intraperitoneal injection of STZ (65 mg/kg body weight). Zinc sulfate was given daily by gavage at a dose of 100 mg/kg body weight every day for 60 days to groups II and IV. At the last day of the experiment, rats were sacrificed, lung tissues were taken. Also, glycoprotein components, tissue factor (TF) activity, protein carbonyl (PC), advanced oxidative protein products (AOPP), hydroxyproline, and enzyme activities in lung tissues were determined. Glycoprotein components, TF activity, lipid peroxidation, non enzymatic glycation, PC, AOPP, hydroxyl proline, lactate dehydrogenase, catalase, superoxide dismutase, myeloperoxidase, xanthine oxidase, adenosine deaminase and prolidase significantly increased in lung tissues of diabetic rats. Also, glutathione levels, paraoxonase, arylesterase, carbonic anhydrase, and Na(+)/K(+)- ATPase activities were decreased. Administration of zinc significantly reversed these effects. Thus, the study indicates that zinc possesses a significantly beneficial effect on the glycoprotein components and oxidant/antioxidant enzyme activities. PMID:26817646

  4. Methadone ameliorates multiple-low-dose streptozotocin-induced type 1 diabetes in mice

    International Nuclear Information System (INIS)

    Type 1 diabetes is an autoimmune disease characterized by inflammation of pancreatic islets and destruction of β cells by the immune system. Opioids have been shown to modulate a number of immune functions, including T helper 1 (Th1) and T helper 2 (Th2) cytokines. The immunosuppressive effect of long-term administration of opioids has been demonstrated both in animal models and humans. The aim of this study was to determine the effect of methadone, a μ-opioid receptor agonist, on type 1 diabetes. Administration of multiple low doses of streptozotocin (STZ) (MLDS) (40mg/kg intraperitoneally for 5 consecutive days) to mice resulted in autoimmune diabetes. Mice were treated with methadone (10mg/kg/day subcutaneously) for 24days. Blood glucose, insulin and pancreatic cytokine levels were measured. Chronic methadone treatment significantly reduced hyperglycemia and incidence of diabetes, and restored pancreatic insulin secretion in the MLDS model. The protective effect of methadone can be overcome by pretreatment with naltrexone, an opioid receptor antagonist. Also, methadone treatment decreased the proinflammatory Th1 cytokines [interleukin (IL)-1β, tumor necrosis factor-α and interferon-γ] and increased anti-inflammatory Th2 cytokines (IL-4 and IL-10). Histopathological observations indicated that STZ-mediated destruction of β cells was attenuated by methadone treatment. It seems that methadone as an opioid agonist may have a protective effect against destruction of β cells and insulitis in the MLDS model of type 1 diabetes

    Full Text Available Aim. To investigate the ameliorating potentials of cocoyam (Colocasia esculenta L. and unripe plantain (Musa paradisiaca L. incorporated feeds on the renal and liver growths of diabetic rats, induced with 55 and 65 mg/kg body weight of Streptozotocin. Method. The blood glucose level of the rats was measured with a glucometer, the protein and glucose and specific gravity (SPGR in the urine samples of the rats were measured using urine assay strips and urinometer respectively. The chemical composition and antioxidant screening of the test feeds were carried out using standard techniques. Results. Administration of the test feeds for 21 days to the diabetic rats of groups 4 and 5, resulted in 58.75% and 38.13% decreases in hyperglycemia and amelioration of their elevated urinary protein, glucose, SPGR, and relative kidney weights. The diabetic rats administered cocoyam incorporated feeds, had 2.71% and 19.52% increases in weight and growth rates, the diabetic rats administered unripe plantain incorporated feeds had 5.12% and 29.52% decreases in weight and growth rates while the diabetic control rats had 28.69%, 29.46%, 248.9% and 250.14% decreases in weights and growth rates. The cocoyam incorporated feeds contained higher antioxidants, minerals and phytochemicals except alkaloids than unripe plantain feed. Conclusion. Cocoyam and unripe plantain could be useful in the management of diabetic nephropathy.

    Full Text Available The present study was conducted to evaluate the therapeutic efficacy of Rhinacanthus nasutus (R. nasutus on mitochondrial and cytosolic enzymes in streptozotocin-induced diabetic rats. The rats were divided into five groups with 6 rats in each group. The methanolic extract of R. nasutus was orally administered at a dose of 200 mg/kg/day, and glibenclamide was administered at a dose of 50 mg/kg/day. All animals were treated for 30 days and were sacrificed. The activities of both intra- and extramitochondrial enzymes including glucose-6-phosphate dehydrogenase (G6PDH, succinate dehydrogenase (SDH, glutamate dehydrogenase (GDH, and lactate dehydrogenase (LDH were measured in the livers of the animals. The levels of G6PDH, SDH, and GDH were significantly reduced in the diabetic rats but were significantly increased after 30 days of R. nasutus treatment. The increased LDH level in diabetic rats exhibited a significant reduction after treatment with R. nasutus. These results indicate that the administration of R. nasutus altered the activities of oxidative enzymes in a positive manner, indicating that R. nasutus improves mitochondrial energy production. Our data suggest that R. nasutus should be further explored for its role in the treatment of diabetes mellitus.

    Oxidative stress has a great role in diabetes and diabetes induced organ damage. Endoplasmic reticulum (ER) stress is involved in the onset of diabetic nephropathy. We hypothesize that ER stress inhibition could protect against kidney injury through anti-oxidative effects. To test whether block ER stress could attenuate oxidative stress and improve diabetic nephropathy in vivo and in vitro, the effect of ursodeoxycholic acid (UDCA), an ER stress inhibitor, on spontaneous diabetic nephropathy db/db mice, ER stress inducer or high glucose-triggered podocytes were studied. Mice were assigned to 3 groups (n=6 per group): control group (treated with vehicle), db/db group (treated with vehicle), and UDCA group (db/db mice treated with 40 mg/kg/d UDCA). After 8 weeks treatment, mice were sacrificed. Blood and kidneys were collected for the assessment of albumin/creatinine ratio, blood urea nitrogen (BUN), serum creatinine (SCr), insulin, total cholesterol, triglyceride, low density lipoprotein cholesterol (LDL-C), oxidized LDL-C, high density lipoprotein cholesterol (HDL-C), non-esterified fatty acid (NEFA), superoxide dismutase (SOD), catalase (CAT), methane dicarboxylic aldehyde (MDA), the expressions of SOD isoforms and glutathione peroxidase 1, as well as histopathological examination. In addition, generation of reactive oxygen species (ROS) was detected by 2'7'-dichlorodihydrofluorescein diacetate (DCFH-DA) fluorescence. The results showed that UDCA alleviated renal ER stress-evoked cell death, oxidative stress, renal dysfunction, ROS production, upregulated the expression of Bcl-2 and suppressed Bax in vivo and in vitro. Hence, inhibition ER stress diminishes oxidative stress and exerts renoprotective effects. PMID:27193377

    Seligman (2002) suggested three paths to well-being, the pursuit of pleasure, the pursuit of meaning, and the pursuit of engagement, later adding two more, positive relationships and accomplishment, in his 2011 version. The contribution of these new components to well-being has yet to be addressed. In an online positive psychology intervention study, we randomly assigned 1624 adults aged 18-78 (M = 46.13; 79.2% women) to seven conditions. Participants wrote down three things they related to either one of the five components of Seligman's Well-Being theory (Conditions 1-5), all of the five components (Condition 6) or early childhood memories (placebo control condition). We assessed happiness (AHI) and depression (CES-D) before and after the intervention, and 1-, 3-, and 6 months afterwards. Additionally, we considered moderation effects of well-being levels at baseline. Results confirmed that all interventions were effective in increasing happiness and most ameliorated depressive symptoms. The interventions worked best for those in the middle-range of the well-being continuum. We conclude that interventions based on pleasure, engagement, meaning, positive relationships, and accomplishment are effective strategies for increasing well-being and ameliorating depressive symptoms and that positive psychology interventions are most effective for those people in the middle range of the well-being continuum.

    The effect of visceral fat removal upon glucose homeostasis, insulin signal transduction, and serum adipokine levels in an animal model of diet-induced obesity and diabetes mellitus (DIO) was evaluated. Swiss mice were initially divided into two groups fed with regular rodent chow or with chow containing 24 g% saturated fat (DIO). DIO mice became obese and overtly diabetic after 8 weeks. DIO mice were then divided into three groups: control, sham, and visceral (epididymal and perinephric) fat removal. All groups were submitted to evaluation of basal glucose and insulin levels and i.p. insulin tolerance test. Insulin signal transduction in muscle was evaluated by immunoprecipitation and immunoblot, and serum adipokine levels were determined by ELISA. DIO mice became diabetic (228 versus 115 mg/dl), hyperinsulinemic (7.59 versus 3.15 ng/ml) and insulin resistant (K(itt) 2.88 versus 4.97%/min) as compared with control. Visceral fat removal partially reverted all parameters (147 mg/dl glucose; 3.82 ng/ml insulin; and 4.20%/min K(itt)). In addition, visceral fat removal completely reversed the impairment of insulin signal transduction through insulin receptor, insulin receptor substrate (IRS)-1, IRS-2 and Akt in muscle. Finally, serum levels of the pro-inflammatory cytokines tumour necrosis factor-alpha, interleukin (IL)-1beta and IL-6 were significantly increased, while adiponectin levels were significantly reduced in DIO mice. After visceral fat removal the levels of adipokines returned to near control levels. The present study shows that removal of visceral fat improves insulin signal transduction and glucose homeostasis in an animal model of diet-induced obesity and diabetes mellitus and these metabolic and molecular outcomes are accompanied by the restoration of adipokine levels.

    Background The purpose of this study was to investigate the association between diabetes and depressive symptoms among Korean women. Methods We performed an analysis of data for 6,572 women aged 30 or over obtained from the Fifth Korean National Health and Nutrition Examination Survey conducted in 2010 to 2011. We examined the presence of depressive symptoms and the treatment of depression according to diabetes status. Results The presence of depressive symptoms was observed in 22.6% of subjects with diabetes. In the multiple logistic regression model, diabetes was associated with an increased risk of depressive symptoms (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.20 to 1.21) but the treatment of depression among diabetics was less common (OR, 0.54; 95% CI, 0.54 to 0.55). Uncontrolled diabetes (glycosylated hemoglobin ≥ 7%) was associated with an increased risk of depressive symptoms (OR, 1.71; 95% CI, 1.69 to 1.73) among diabetics. Conclusion Physicians should manage individuals with diabetes in consideration of the presence of depressive symptoms, especially in those with uncontrolled diabetes. PMID:24921031

    Objectives. We investigated whether amlodipine could improve angiogenic responses in a diabetic rat model of acute myocardial infarction (AMI) through improving bone marrow endothelial progenitor cell (EPC) mobilization, in the same way as angiotensin converting enzyme inhibitors. Methods. After induction of AMI by coronary artery ligation, diabetic rats were randomly assigned to receive perindopril (2 mgkg(-1) day(-1)), amlodipine (2.5 mgkg(-1) day(-1)), or vehicle by gavage (n = 20 per group). Circulating EPC counts before ligation and on days 1, 3, 5, 7, 14, and 28 after AMI were measured in each group. Microvessel density, cardiac function, and cardiac remodeling were assessed 4 weeks after treatment. The signaling pathway related to EPC mobilization was also measured. Results. Circulating EPC count in amlodipine- and perindopril-treated rats peaked at day 7, to an obvious higher level than the control group peak which was reached earlier (at day 5). Rats treated with amlodipine showed improved postischemia neovascularization and cardiac function, together with reduced cardiac remodeling, decreased interstitial fibrosis, and cardiomyocyte apoptosis. Amlodipine treatment also increased cardiac SDF-1/CXCR4 expression and gave rise to activation of VEGF/Akt/eNOS signaling in bone marrow. Conclusions. Amlodipine promotes neovascularization by improving EPC mobilization from bone marrow in diabetic rats after AMI, and activation of VEGF/Akt/eNOS signaling may in part contribute to this.

    Background. Sesbania grandiflora has been traditionally used as antidiabetic, antioxidant, antipyretic, and expectorant and in the management of various ailments. Materials and Methods. The study evaluates the antidiabetic activity of methanolic extract of Sesbania grandiflora (MESG) in type 2 diabetic rats induced by low dose streptozotocine and high fat diet. Diabetic rats were given vehicle, MESG (200 and 400 mg/kg, p.o.), and the standard drug, metformin (10 mg/kg), for 28 days. During the experimental period, body weight, abdominal girth, food intake, fasting serum glucose, urine analyses were measured. Insulin tolerance test was carried out on 25th day of drug treatment period. Serum analyses for lipid profile and SGOT and SGPT and serums creatinine, urea, protein, SOD, and MDA were also carried out. At the end of the experiment, animals were euthanized, the liver and pancreas were immediately dissected out, and the ratio of pancreas to body weight and hepatic glycogen were calculated. Results. MESG (200 and 400 mg/kg, p.o.) induced significant reduction (P < 0.05) of raised blood glucose levels in diabetic rats and also restored other parameters to normal level. Conclusion. Therefore, it is concluded that MESG has potential antihyperglycemic and antihyperlipemic activities and alleviate insulin resistance conditions. PMID:27313954

  5. The heme oxygenase system suppresses perirenal visceral adiposity, abates renal inflammation and ameliorates diabetic nephropathy in Zucker diabetic fatty rats.

    Full Text Available The growing incidence of chronic kidney disease remains a global health problem. Obesity is a major risk factor for type-2 diabetes and renal impairment. Perirenal adiposity, by virtue of its anatomical proximity to the kidneys may cause kidney disease through paracrine mechanisms that include increased production of inflammatory cytokines. Although heme-oxygenase (HO is cytoprotective, its effects on perirenal adiposity and diabetic nephropathy in Zucker-diabetic fatty rats (ZDFs remains largely unclear. Upregulating the HO-system with hemin normalised glycemia, reduced perirenal adiposity and suppressed several pro-inflammatory/oxidative mediators in perirenal fat including macrophage-inflammatory-protein-1α (MIP-1α, endothelin (ET-1, 8-isoprostane, TNF-α, IL-6 and IL-1β. Furthermore, hemin reduced ED1, a marker of pro-inflammatory macrophage-M1-phenotype, but interestingly, enhanced markers associated with anti-inflammatory M2-phenotype such as ED2, CD206 and IL-10, suggesting that hemin selectively modulates macrophage polarization towards the anti-inflammatory M2-phenotype. These effects were accompanied by increased adiponectin, HO-1, HO-activity, atrial-natriuretic peptide (ANP, and its surrogate marker, urinary-cGMP. Furthermore, hemin reduced renal histological lesions and abated pro-fibrotic/extracellular-matrix proteins like collagen and fibronectin that deplete nephrin, an important transmembrane protein which forms the scaffolding of the podocyte slit-diaphragm allowing ions to filter but not massive excretion of proteins, hence proteinuria. Correspondingly, hemin increased nephrin expression in ZDFs, reduced markers of renal damage including, albuminuria/proteinuria, but increased creatinine-clearance, suggesting improved renal function. Conversely, the HO-blocker, stannous-mesoporphyrin nullified the hemin effects, aggravating glucose metabolism, and exacerbating renal injury and function. The hemin effects were less

    Introducción: la diabetes mellitus (DM) conlleva un aumento de la ingesta de líquidos y del gasto urinario por el estado hiperosmolar al que induce a los que la padecen. El objetivo fue evaluar la prevalencia de síntomas urinarios en mujeres con DM, su impacto en la calidad de vida y su asociación con el tiempo de diagnóstico de DM, neuropatía y control glucémico. Métodos: en una cohorte de mujeres del programa DiabetIMSS evaluamos, de enero de 2011 a enero de 2013, sus antecedentes, neuropatía y síntomas urinarios, control glucémico e impacto en la calidad de vida mediante entrevista, medición de peso, exámenes paraclínicos y cuestionarios (ICIQ-SF, IPSS y QoL). Resultados: entrevistamos 169 mujeres con mediana de edad de 58 años (29-85) y mediana al diagnóstico de DM de 9 años (0.5-31). Presentaron síntomas urinarios 128 (75.7 %), principalmente incontinencia urinaria de esfuerzo y urgencia (45.3 y 40.6 %), síntomas obstructivos (25 %) e irritativos (10.1 %). Su impacto en la calidad de vida fue de leve a moderado (91.1 %). Presentaron neuropatía 154 (91.1 %), con un tiempo mayor de evolución en las pacientes sintomáticas (12 frente a 4.8 meses), igualmente prevalecieron los síntomas urinarios en aquellas con neuropatía de más de un año de evolución, p < 0.05. Conclusión: la prevalencia de síntomas urinarios en mujeres diabéticas es elevada, con el tiempo de evolución de neuropatía como único factor asociado. El tiempo de evolución de DM y una determinación de HbA1c no evidenciaron asociación significativa.

    Full Text Available BACKGROUND: Pluri-potent bone marrow stromal cells (MSCs provide an attractive opportunity to generate unlimited glucose-responsive insulin-producing cells for the treatment of diabetes. We explored the potential for human MSCs (hMSCs to be differentiated into glucose-responsive cells through a non-viral genetic reprogramming approach. METHODS AND FINDINGS: Two HMSC lines were transfected with three genes: PDX-1, NeuroD1 and Ngn3 without subsequent selection, followed by differentiation induction in vitro and transplantation into diabetic mice. Human MSCs expressed mRNAs of the archetypal stem cell markers: Sox2, Oct4, Nanog and CD34, and the endocrine cell markers: PDX-1, NeuroD1, Ngn3, and Nkx6.1. Following gene transfection and differentiation induction, hMSCs expressed insulin in vitro, but were not glucose regulated. After transplantation, hMSCs differentiated further and approximately 12.5% of the grafted cells expressed insulin. The graft bearing kidneys contained mRNA of insulin and other key genes required for the functions of beta cells. Mice transplanted with manipulated hMSCs showed reduced blood glucose levels (from 18.9+/-0.75 to 7.63+/-1.63 mM. 13 of the 16 mice became normoglycaemic (6.9+/-0.64 mM, despite the failure to detect the expression of SUR1, a K(+-ATP channel component required for regulation of insulin secretion. CONCLUSIONS: Our data confirm that hMSCs can be induced to express insulin sufficient to reduce blood glucose in a diabetic mouse model. Our triple gene approach has created cells that seem less glucose responsive in vitro but which become more efficient after transplantation. The maturation process requires further study, particularly the in vivo factors influencing the differentiation, in order to scale up for clinical purposes.

    Epidemiological and clinical studies have demonstrated that a growing list of natural products, as components of the daily diet or phytomedical preparations, are a rich source of antioxidants. Boldine [(S)-2,9-dihydroxy-1,10-dimethoxy-aporphine], an aporphine alkaloid, is a potent antioxidant found in the leaves and bark of the Chilean boldo tree. Boldine has been extensively reported as a potent "natural" antioxidant and possesses several health-promoting properties like anti-inflammatory, antitumor promoting, antidiabetic, and cytoprotective. Boldine exhibited significant endothelial protective effect in animal models of hypertension and diabetes mellitus. In isolated thoracic aorta of spontaneously hypertensive rats, streptozotocin-induced diabetic rats, and db/db mice, repeated treatment of boldine significantly improved the attenuated acetylcholine-induced endothelium-dependent relaxations. The endothelial protective role of boldine correlated with increased nitric oxide levels and reduction of vascular reactive oxygen species via inhibition of the nicotinamide adenine dinucleotide phosphate oxidase subunits, p47 and nicotinamide adenine dinucleotide phosphate oxidase 2, and angiotensin II-induced bone morphogenetic protein-4 oxidative stress cascade with downregulation of angiotensin II type 1 receptor and bone morphogenetic protein-4 expression. Taken together, it seems that boldine may exert protective effects on the endothelium via several mechanisms, including protecting nitric oxide from degradation by reactive oxygen species as in oxidative stress-related diseases. The present review supports a complimentary therapeutic role of the phytochemical, boldine, against endothelial dysfunctions associated with hypertension and diabetes mellitus by interfering with the oxidative stress-mediated signaling pathway.

    Directory of Open Access Journals (Sweden)

    Derek M Erion

    Full Text Available Hyperglycemia resulting from type 2 diabetes mellitus (T2DM is the main cause of diabetic complications such as retinopathy and neuropathy. A reduction in hyperglycemia has been shown to prevent these associated complications supporting the importance of glucose control. Glucokinase converts glucose to glucose-6-phosphate and determines glucose flux into the β-cells and hepatocytes. Since activation of glucokinase in β-cells is associated with increased risk of hypoglycemia, we hypothesized that selectively activating hepatic glucokinase would reduce fasting and postprandial glucose with minimal risk of hypoglycemia. Previous studies have shown that hepatic glucokinase overexpression is able to restore glucose homeostasis in diabetic models; however, these overexpression experiments have also revealed that excessive increases in hepatic glucokinase activity may also cause hepatosteatosis. Herein we sought to evaluate whether liver specific pharmacological activation of hepatic glucokinase is an effective strategy to reduce hyperglycemia without causing adverse hepatic lipids changes. To test this hypothesis, we evaluated a hepatoselective glucokinase activator, PF-04991532, in Goto-Kakizaki rats. In these studies, PF-04991532 reduced plasma glucose concentrations independent of changes in insulin concentrations in a dose-dependent manner both acutely and after 28 days of sub-chronic treatment. During a hyperglycemic clamp in Goto-Kakizaki rats, the glucose infusion rate was increased approximately 5-fold with PF-04991532. This increase in glucose infusion can be partially attributed to the 60% reduction in endogenous glucose production. While PF-04991532 induced dose-dependent increases in plasma triglyceride concentrations it had no effect on hepatic triglyceride concentrations in Goto-Kakizaki rats. Interestingly, PF-04991532 decreased intracellular AMP concentrations and increased hepatic futile cycling. These data suggest that

    Full Text Available Abstract Background Vulnerability to stress has been associated to distress, emotional distress symptoms and metabolic control in type 2 diabetes mellitus (T2DM patients as well. Furthermore some conflicting results were noticed. We aimed to evaluate the effect over metabolic control in what concerns vulnerability to stress beyond depressive and anxiety symptoms. Findings This cross-sectional study assessed 273 T2DM patients with depressive and anxiety symptoms using the Hospital Anxiety Depression Scale (HADS and the 23 Questions to assess Vulnerability to Stress (23QVS, along with demographic and clinical diabetes-related variables. Hierarchical logistic regression models were used to investigate predictors of poor glycemic control. The results showed an association of depressive symptoms (odds ratio = 1.12, 95%CI = 1.01-1.24, P = 0.030 with increased risk of poor glycemic control. Anxiety symptoms and vulnerability to stress on their own were not predictive of metabolic control, respectively (odds ratio = 0.92, 95%CI = 0.84-1.00, P = 0.187 and odds ratio = 0.98, 95%CI = 0.95-1.01, P = 0.282. Conclusions Our data suggested that vulnerability to stress was not predictive of poor glycemic control in T2DM, but depressive symptoms were.

    Background Gastrointestinal (GI) symptoms are common in patients with type 2 diabetes mellitus (T2DM). Rebamipide is an effective gastric cytoprotective agent, but there are few data on its usefulness in T2DM. The aim of this study is to evaluate the improvement of GI symptoms after rebamipide treatment in patients with T2DM. Methods Patients with T2DM and atypical GI symptoms were enrolled. They took rebamipide (100 mg thrice daily) for 12 weeks and filled out the diabetes bowel symptom questionnaire (DBSQ) before and after rebamipide treatment. The DBSQ consisted of 10 questions assessing the severity of GI symptoms by a 1 to 6 scoring system. Changes in the DBSQ scores before and after rebamipide treatment were analyzed to evaluate any improvements of GI symptoms. Results A total of 107 patients were enrolled, and 84 patients completed the study. The mean age was 65.0±7.8, 26 patients were male (24.8%), the mean duration of T2DM was 14.71±9.12 years, and the mean glycosylated hemoglobin level was 6.97%±0.82%. The total DBSQ score was reduced significantly from 24.9±8.0 to 20.4±7.3 before and after rebamipide treatment (P<0.001). The DBSQ scores associated with reflux symptoms, indigestion, nausea or vomiting, abdominal bloating or distension, peptic ulcer, abdominal pain, and constipation were improved after rebamipide treatment (P<0.05). However, there were no significant changes in symptoms associated with irritable bowel syndrome, diarrhea, and anal incontinence. No severe adverse events were reported throughout the study. Conclusion Rebamipide treatment for 12 weeks improved atypical GI symptoms in patients with T2DM. PMID:27098506

    In this study, we mainly investigated the effects of Shengmai San (SMS) on diabetic cardiomyopathy (DCM) in db/db mice. The db/db mice were randomly divided into model group and SMS group, while C57BLKS/J inbred mice were used as controls. After 24-week treatment, blood glucose, body weight, and heart weight were determined. Hemodynamic changes in the left ventricle were measured using catheterization. The myocardial structure and subcellular structural changes were observed by HE staining and electron microscopy; the myocardium collagen content was quantified by Masson staining. To further explore the protective mechanism of SMS, we analyzed the expression profiles of fibrotic related proteins. Compared to nondiabetic mice, db/db mice exhibited enhanced diastolic myocardial dysfunction and adverse structural remodeling. Higher expression of profibrotic proteins and lower levels of extracellular matrix degradation were also observed. After SMS oral administration for 24 weeks, cardiac dysfunction, hypertrophy, and fibrosis in diabetic mice were greatly improved. Moreover, increased profibrotic protein expression was strongly reversed by SMS treatment in db/db mice. The results demonstrate that SMS exerts a cardioprotective effect against DCM by attenuating myocardial hypertrophy and fibrosis via a TGF-β dependent pathway. PMID:27200101

    Full Text Available Background: Diabetes mellitus is a chronic disease. Decreasing postprandial hyperglycemia by retarding glucose absorption through inhibiting carbohydrates digesting enzymes (α-amylase and α-glucosidase is one of many approaches used for the management of this disease. This study was aimed at evaluating the normoglycaemic potential of Helianthus annuus leaf. Methods: The effect of the in vitro inhibitory of different extracts (acetone, ethyl acetate and hexane of the plant was assessed on the activities of diabetes-related enzymes (α-amylase and α-glucosidase. Results: The hexane extract of H. annuus leaf displayed the best inhibitory activity against α-amylase and α-glucosidase as indicated by the IC50 values (3.92 ± 0.02 mg mL-1 and (3.29 ± 0.12 mg mL-1, respectively. Lineweaver-Burk plot of inhibition of α-amylase and α-glucosidase by this extract showed that it was competitive and non-competitive mode, respectively. Conclusion: H. annuus leaf possesses hypoglycaemic potential which may be due to the inhibition of pancreatic α-amylase and intestinal α-glucosidase.

    Diabetes mellitus is considered as a risk factor for Alzheimer disease. The aim of the present study was to evaluate the possibility whether treadmill exercise ameliorates Alzheimer disease-associated memory loss in the diabetes mellitus. For this study, the effects of treadmill exercise on short-term memory and spatial learning ability in relation with Wnt signaling pathway were evaluated using the streptozotocin (STZ)-induced diabetic rats. Diabetes was induced by intraperitoneal injection of STZ. Step-down avoidance task and 8-arm radial maze test were performed for the memory function. Immunohistochemistry for 5-bro-mo-2'-deoxyridine (BrdU) and doublecortin (DCX) and Western blot for Wnt3 and glycogen synthase kinase-3β (GSK-3β) were conducted. The rats in the exercise groups were made to run on the treadmill for 30 min per one day, 5 times a week, during 12 weeks. In the present results, short-term memory and spatial learning ability were deteriorated by induction of diabetes. Treadmill exercise improved short-term memory and spatial learning ability in the diabetic rats. The numbers of BrdU-positive and DCX-positive cells in the hippocampal dentate gyrus were decreased by induction of diabetes. Treadmill exercise increased these numbers in the diabetic rats. Wnt3 expression in the hippocampus was decreased and GSK-3β expression in the hippocampus was increased by induction of diabetes. Treadmill exercise increased Wnt3 expression and suppressed GSK-3β expression in the diabetic rats. The present study suggests that treadmill exercise alleviates Alzheimer disease-associated memory loss by increasing neurogenesis through activating Wnt signaling pathway in the diabetic rats.

    Depression and diabetes are independent risk factors for one another, and both are associated with increased risk of cognitive decline. Diabetes patients with lower cognitive function are more likely to suffer poorer health outcomes. However, the role of depression in cognitive decline among people with diabetes is not well understood. This systematic review assessed whether adults with comorbid diabetes and depression or depressive symptoms exhibit greater cognitive decline relative to individuals with diabetes alone. Searches were run in CINAHL, the Cochrane Central Register of Controlled Trials, EMBASE, PsycINFO, and PubMed (MEDLINE) with no time or language restrictions. Studies were eligible for inclusion if they were of any quantitative study design, included participants aged 18 years or older with diabetes mellitus of which some must have presented with current depression, and measured cognition as an outcome. The Cochrane Collaboration's Risk Of Bias In Non-randomized Studies-of Interventions tool was used for quality assessment of each study and its collected outcome. Fifteen articles were included in the final analysis. The high degree of heterogeneity in exposures, outcomes, and participant characteristics precluded a meta-analysis of any of the studies, and the risk of bias observed in these studies limits the strength of the evidence. Nonetheless, this review found the presence of comorbid depression was associated with poorer cognitive outcomes than for persons with diabetes alone. While large-scale preventive efforts must address epidemic levels of diabetes and its comorbidities, on the patient level healthcare professionals must be cognizant of the added difficulties that depression poses to patients and the extra support required to management diabetes in these cases. This systematic review is registered with the University of York Centre for Reviews and Dissemination under registration number 2015:CRD42015025122. PMID:27526176

    Background Depression is associated with a variety of diabetes complications, including diabetic retinopathy, nephropathy, neuropathy, and macrovascular complications. The prevalence of the symptoms of anxiety (32%) and depression (22.4%) in patients with diabetes is considerably higher than in general population samples (10%). The aim of this study was to evaluate the prevalence and determinants of anxiety and depression symptoms in patients with type 2 diabetes (T2DM). Material/Methods This survey was conducted during 2007–2010. In total, 1500 patients were invited to participate in the study. The Hospital Anxiety and Depression Scale (HADS) was used to measure depression and anxiety for the evaluation of the depressive state and anxiety. Statistical analysis was carried out using SPSS 17.0. Results More than 70% of all respondents who participated in the study had diabetes mellitus complications (72.2%). The prevalence of mild to severe depression score was 28.5% (95% CI 25.7–31.4). The prevalence of anxiety was 42.4% (95% CI 39.3–45.5). Anxiety was more frequent among females (46.8%) than among males (34.7%) (p<0.001). A significant negative trend was observed between prevalence of anxiety and depression, and age and education (p for trend <0.001). Conclusions A significant association between depression and diabetic complications was identified (p<0.05). Duration of diabetes was a risk factor significantly associated with higher scores of anxiety among the patients with T2DM. PMID:24492643

    AIM:To investigate the effects of the Chinese herbal decoction,Yi-Qi-Zeng-Min-Tang (YQZMT),on insulin resistance in type 2 diabetic rats. METHODS:Sprague-Dawley rats were divided into two dietary regiments by feeding either normal pellet diet (NPD) or high fat diet (HFD).Four weeks later,the HFD-fed rats were injected intraperitoneally with lowdose streptozotocin (STZ).Rats with non-fasting blood glucose level ≥ 16.67 mmol/L were considered type 2 diabetic and further divided into five subgroups:the type 2 diabetes model group,low-dose,medium-dose and high-dose YQZMT groups,and rosiglitazone group. Age-matched NPD-fed rats served as controls.YQZMT or rosiglitazone were administered for 8 wk.Intraperitoneal glucose and insulin tolerance tests were performed before and after the treatment to measure the glucose tolerance and insulin sensitivity.Serum levels of biochemical parameters,adipocytokines,such as tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6),as well as free fatty acids (FFAs),were also analyzed. RESULTS:There was significant elevation of insulin resistance and serum levels of fasting glucose (12.82 ± 1.08 mmol/L vs 3.60 ± 0.31 mmol/L,P < 0.01),insulin (7197.36 ± 253.89 pg/mL vs 4820.49 ± 326.89 pg/mL, P < 0.01),total cholesterol (TC) (8.40 ± 0.49 mmol/L vs 2.14 ± 0.06 mmol/L,P < 0.01),triglyceride (2.24 ± 0.12 mmol/L vs 0.78 ± 0.05 mmol/L,P < 0.01),low-density lipoprotein cholesterol (LDL-c) (7.84 ± 0.51 mmol/L vs 0.72 ± 0.04 mmol/L,P < 0.01) and decrease in high-density lipoprotein cholesterol (HDL-c) (0.57 ± 0.03 mmol/L vs 1.27 ± 0.03 mmol/L,P < 0.01) in the low-dose STZ and high-fat diet induced type 2 diabetic group when compared with the control group. Administration of YQZMT induced dose- and timedependent changes in insulin resistance,glucose and lipid profile,and reduced levels of FFA,TNF-α and IL-6 in the type 2 diabetic rats.After the treatment, compared with the diabetic group,the insulin resistance was ameliorated in the

    Keisuke Ishizawa

    Full Text Available Diabetic nephropathy (DN is the major cause of end-stage renal failure. Oxidative stress is implicated in the pathogenesis of DN. Nitrosonifedipine (NO-NIF is a weak calcium channel blocker that is converted from nifedipine under light exposure. Recently, we reported that NO-NIF has potential as a novel antioxidant with radical scavenging abilities and has the capacity to treat vascular dysfunction by exerting an endothelial protective effect. In the present study, we extended these findings by evaluating the efficacy of NO-NIF against DN and by clarifying the mechanisms of its antioxidative effect. In a model of type 2 DN (established in KKAy mice, NO-NIF administration reduced albuminuria and proteinuria as well as glomerular expansion without affecting glucose metabolism or systolic blood pressure. NO-NIF also suppressed renal and systemic oxidative stress and decreased the expression of intercellular adhesion molecule (ICAM-1, a marker of endothelial cell injury, in the glomeruli of the KKAy mice. Similarly, NO-NIF reduced albuminuria, oxidative stress, and ICAM-1 expression in endothelial nitric oxide synthase (eNOS knockout mice. Moreover, NO-NIF suppressed urinary angiotensinogen (AGT excretion and intrarenal AGT protein expression in proximal tubular cells in the KKAy mice. On the other hand, hyperglycemia-induced mitochondrial superoxide production was not attenuated by NO-NIF in cultured endothelial cells. These findings suggest that NO-NIF prevents the progression of type 2 DN associated with endothelial dysfunction through selective antioxidative effects.

    Full Text Available Diabetes mellitus type 1 is associated with an enhanced apoptosis of different cells and tissues, accelerating occurrence of diabetic microvascular complications. The aim of our study was to determine spontaneous apoptotic potential of the monocyte subsets in juvenile-onset complication-free diabetes mellitus type 1 and to compare them with the corresponding values of the healthy. Moreover, we wanted to assess effects of TNF-R1 blocking agents and those of general TNF-α blocker (Infliximab on spontaneous apoptosis of monocytes. Sixty randomly selected DM1 patients (14.5 ± 3.2 years and 30 healthy (13.5 ± 2.8 years volunteers were enrolled in the study. Our results indicate that three monocyte subsets are distinguishable in the groups of young diabetic patients and the healthy, similarly to in the blood of adults. DM1 patients were characterized by higher values of apoptotic monocytes than the healthy. The manipulation with drugs inhibiting TNF-R1 expression diminished the pool of CD16+ apoptotic monocytes. Infliximab reduced the apoptotic CD16− cells. In conclusion, diabetes mellitus type 1 is associated with greater apoptosis of three monocyte subsets which may contribute to the development of microvascular complications. TNF-α modifiers appear to ameliorate monocyte apoptosis. They may be useful for controlling excessive monocyte apoptosis in diabetic patients.

    Objective For patients with diabetes, erectile dysfunction (ED) is common and greatly affects quality of life. However, these patients often exhibit a poor response to first-line oral phosphodiesterase type 5 inhibitors. The aim of this study was to investigate whether taurine, a sulfur-containing amino acid, affects diabetic ED (DED). Methods Type 1 diabetes mellitus was induced in male rats using streptozotocin. After 12 weeks, an apomorphine test was conducted to confirm DED. Only rats with DED were administered taurine or vehicle for four weeks. Age-matched nondiabetic rats were administered saline intraperitoneally for four weeks. Erectile function was evaluated by electrical stimulation of the cavernous nerve. Histologic and molecular alterations of the corpus cavernosum also were analyzed. Results Erectile function was significantly reduced in the diabetic rats compared with in the nondiabetic rats, and was ameliorated in the diabetic rats treated with taurine. The corpus cavernosum of the rats with DED exhibited severe fibrosis and decreased smooth muscle content. Deposition of extracellular matrix proteins was increased in the diabetic rats, while expression of endothelial nitric oxide synthase/cyclic guanosine monophosphate/nitric oxide pathway–related proteins was reduced. Taurine supplementation restored erectile response as well as histologic and molecular alterations. Conclusions Taurine supplementation improves erectile function in rats with DED probably by potential antifibrotic activity. This finding provides evidence for a potential new therapy for DED.

    Full Text Available Several studies point out that oxidative stress maybe a major culprit in diabetic nephropathy. Aqueous extract of Hibiscus sabdariffa L. (HSE has been demonstrated as having beneficial effects on anti-oxidation and lipid-lowering in experimental studies. This study aimed at investigating the effects of Hibiscus sabdariffa L. on diabetic nephropathy in streptozotocin induced type 1 diabetic rats. Our results show that HSE is capable of reducing lipid peroxidation, increasing catalase and glutathione activities significantly in diabetic kidney, and decreasing the plasma levels of triglyceride, low-density lipoprotein (LDL and increasing high-density lipoprotein (HDL value. In histological examination, HSE improves hyperglycemia-caused osmotic diuresis in renal proximal convoluted tubules (defined as hydropic change in diabetic rats. The study also reveals that up-regulation of Akt/Bad/14-3-3γ and NF-κB-mediated transcription might be involved. In conclusion, our results show that HSE possesses the potential effects to ameliorate diabetic nephropathy via improving oxidative status and regulating Akt/Bad/14-3-3γ signaling.

    Diabetic nephropathy (DN) is one of the most frequent complications in diabetes mellitus. This study aimed to explore whether Danshen injection is protective to renal tissue in diabetes. Intraperitoneal injection of streptozotocin (STZ) (60mg/kg) was used to induce diabetes in rats. Some STZ-induced diabetic rats were also intraperitoneally injected with Danshen solution at two different dosages (0.5 or 1ml/kg/day) for 6weeks. Our results showed that serum creatinine (sCr) and blood urea nitrogen were significantly increased in STZ-induced diabetic rats, which was alleviated upon Danshen injection. Danshen injection was also found to ameliorate hypertrophy and dilatation of renal tubule and glomeruli possibly by decreasing the expression of collagen and fibronectin in association with suppression of TGF-β1/Smad pathway. Further investigation revealed that Danshen injection could increase the activity of superoxide dismutase (SOD), and reduce reactive oxygen species (ROS) and malondialdehyde (MDA) levels in STZ-induced diabetic rats, indicating suppression of oxidative stress. In addition, we also found that Danshen injection could suppress IκB/NF-κB signaling pathway and reduce the level of a number of pro-inflammatory factors, including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6) in the diabetic renal tissue, indicating suppression of inflammation. In conclusion, our results demonstrated that Danshen injection may rescue STZ-induced diabetic nephropathy, possibly via suppressing the oxidative stress, inflammatory responses and fibrosis progression.

    Full Text Available Male accessory gland inflammation or infection (MAGI is a potentially underdiagnosed complication of type 2 diabetes (DM2; specifically, we reported in a recent study that the frequency of MAGI was 43% among DM2 patients. In previous studies, we have demonstrated that diabetic autonomic neuropathy (DAN is associated with a peculiar ultrasound characterization of the seminal vesicles (SVs in DM2 patients. The aim of the present study was to evaluate the frequency of MAGI in two different categories of DM2 patients (i.e. patients with and without symptoms that possibly reflect DAN and the respective ultrasound characterizations. Sixty DM2 patients with a mean (± s.e.m. age of 42.0 ± 6.0 years (range: 34-47 years were classified according to the presence or the absence of symptoms that could possibly reflect DAN (group A: DM2 with symptoms possibly reflecting DAN, n = 28 patients and group B: DM2 without symptoms possibly reflecting DAN, n = 32 patients. The patients in Group A exhibited a significantly higher frequency of MAGI compared with those in group B patients (P < 0.05; moreover, the Group A patients exhibited a significantly higher frequency of ultrasound signs suggestive of vesiculitis (P < 0.05. Finally, the concentrations of lymphocytes but not the concentrations of the leukocytes in the semen were significantly higher (P < 0.05 in group A compared with group B.

    We estimated the key molecules related to Type 2 diabetes mellitus (T2DM) in adipose, liver, and muscle tissues, from nonobese diabetic Goto-Kakizaki (GK) rats and their Wistar controls, by computationally analyzing the expression profiles in open source data. With the aid of information from previous reports, Rev-erbα in adipose tissue emerged as one of the most plausible candidates. Here, in animal models, including GK rats surgically treated to ameliorate T2DM, we examined the association of Rev-erbα in adipose tissue with T2DM progression. After analyses of the Rev-erbα mRNA expression in the adipose tissue of our animal models, we compared the Rev-erbα protein expression levels in the adipose, liver, and muscle tissues of GK and Wistar controls at the ages of 1 mo (M), 3M, and 6M. The Rev-erbα protein levels in adipose tissue showed a distinctive pattern, with the negative correlation of an increasing trend in GK rats, and a decreasing trend in Wistar rats during aging, from those in liver and muscle tissues. Moreover, dysregulation of the circadian Rev-erbα expression in the adipose tissue of 6-mo-old GK rats was also observed. In particular, we ameliorated T2DM in GK rats by gastric bypass surgery, and revealed that T2DM amelioration in diabetic GK rats was associated with improved circadian Rev-erbα expression, in a comparison between the surgically treated and untreated GK rats. The roles of Rev-erbα in adipose tissue were further investigated by observations of Rev-erbα-related molecules, with reference to previous reports.

    Diabetic encephalopathy is one of the most prevalent chronic complications of diabetes mellitus (DM), but there is currently no effective method of prevention nor proven therapeutic regimen for it. In this study, we investigated the effects of calycosin on cognitive behavior and the potential mechanism involved in streptozocin-induced diabetic rats. The effects of diabetes and calycosin treatment on spatial learning and memory were evaluated using the Morris Water Maze, passive avoidance and motor coordination tests. Histological analysis of the hippocampus cornu ammonis 1 (CA1) region was conducted in rats. The decreased expression of the synapsin (SYN) and postsynatptic density protein (PSD-95), as well as brain-derived neurotrophic factor (BDNF) in diabetic rats was measured by quantitative real-time PCR and western blot. Treatment with calycosin promoted a reduction in the expression of SYN, PSD-95 and BDNF. In addition, diabetic rats showed increased MDA levels, and decreased SOD levels and GSH-Px activities in the hippocampus, as well as increased AChE activity in the cerebral cortex; these changes were reversed by calycosin supplementation. Thus, the impairment of learning and memory in STZ-induced diabetic rats was alleviated by calycosin, and that the degree of alleviation was associated with oxidative stress. We also found that calycosin treatment significantly stimulated Akt phosphorylation and decreased GSK-3β and tau phosphorylation, and that these changes could be restored by the PI3K/Akt inhibitor LY294002. In conclusion, calycosin had a beneficial effect on the amelioration, prevention and treatment of diabetes-associated cognitive deficits, through its involvement in oxidative stress, synaptic function and the PI3K/Akt/GSK-3β pathway.

    This study evaluated the associations between depressive symptoms, emotion dysregulation and bulimic symptoms in youth with type 1 diabetes (T1D) in the context of the diagnosis and treatment of T1D. Study participants were 103 youth in 2 distinct groups: newly diagnosed (New) or transitioning to pump therapy (continuous subcutaneous insulin infusion [CSII]; "Pump"), who completed questionnaires regarding symptoms of depression, emotion dysregulation, and bulimia. Glycemic control (A1c), height, weight, and questionnaires were evaluated within 10 days of diagnosis (n = 58) or at education/clinic visit before starting insulin utilizing CSII (n = 45). In the newly diagnosed group, only depression accounted for significant variance in bulimia scores (β = .47, P depressive symptoms and emotion dysregulation were associated with greater bulimic symptoms. Depressive symptoms and emotion dysregulation, an indicator of poor coping/behavioral control, could help explain adoption of disordered eating behaviors in youth with T1D who are transitioning to pump therapy.

    Objective: To explore the protective effect of the drug Semecarpus anacardium (S. anacardium) on altered glucose metabolism in diabetic rats. Methods: Type 2 diabetes mellitus was induced by feeding rats with high fat diet followed by single intraperitoneal injection of streptozotocin (STZ) (35 mg/kg b.w.). Seven days after STZ induction, diabetic rats received nut milk extract ofS. anacardium Linn. nut milk extract orally at a dosage of 200 mg/kg daily for 4 weeks. The effect of nut milk extract of S. anacardium on blood glucose, plasma insulin, glucose metabolising enzymes and GSK were studied. Results: Treatment with SA extract showed a significant reduction in blood glucose levels and increase in plasma insulin levels and also increase in HOMA - β and decrease in HOMA -IR. The drug significantly increased the activity of glycolytic enzymes and glucose-6-phosphate dehydrogenase activity and increased the glycogen content in liver of diabetic rats while reducing the activities of gluconeogenic enzymes. The drug also effectively ameliorated the alterations in GSK-3 mRNA expression. Conclusions: Overall, the present study demonstrates the possible mechanism of glucose regulation of S. anacardium suggestive of its therapeutic potential for the management of diabetes mellitus.

  19. C-C chemokine receptor 2 inhibitor ameliorates hepatic steatosis by improving ER stress and inflammation in a type 2 diabetic mouse model.

    Full Text Available Hepatic steatosis is the accumulation of excess fat in the liver. Recently, hepatic steatosis has become more important because it occurs in the patients with obesity, type 2 diabetes, and hyperlipidemia and is associated with endoplasmic reticulum (ER stress and insulin resistance. C-C chemokine receptor 2 (CCR2 inhibitor has been reported to improve inflammation and glucose intolerance in diabetes, but its mechanisms remained unknown in hepatic steatosis. We examined whether CCR2 inhibitor improves ER stress-induced hepatic steatosis in type 2 diabetic mice. In this study, db/db and db/m (n = 9 mice were fed CCR2 inhibitor (2 mg/kg/day for 9 weeks. In diabetic mice, CCR2 inhibitor decreased plasma and hepatic triglycerides levels and improved insulin sensitivity. Moreover, CCR2 inhibitor treatment decreased ER stress markers (e.g., BiP, ATF4, CHOP, and XBP-1 and inflammatory cytokines (e.g., TNFα, IL-6, and MCP-1 while increasing markers of mitochondrial biogenesis (e.g., PGC-1α, Tfam, and COX1 in the liver. We suggest that CCR2 inhibitor may ameliorate hepatic steatosis by reducing ER stress and inflammation in type 2 diabetes mellitus.

    2012-02-01

    Full Text Available Esophageal intramural pseudodiverticulosis (EIPD is a rare disease of unknown etiology that displays multiple pseudodiverticula radiologically, leading to benign esophageal stricture. Dysphagia, which sometimes slowly progresses, is the main symptom in the majority of cases. We here report a 59-year-old male EIPD patient who suffered from severe dysphagia. Radiography and endoscopy of this patient disclosed a severe constriction in the upper thoracic esophagus. Although we tried several endoscopic procedures including frequent endoscopic balloon dilatation (EBD, the effect was very limited and his dysphagia relapsed shortly after the treatments. During the procedures, we noticed some white, thick, creamy liquid emerging from the orifices of EIPD, and PAS staining of biopsy specimens revealed infection with Candida albicans. Hence, the patient was given anti-fungal medicine in addition to EBD. The additional treatment with anti-fungal medicine dramatically improved his symptoms and the esophageal constriction. This case suggests that anti-fungal treatment is an effective first-line therapy even against a severe form of esophageal constriction in EIPD.

  2. Associations between depression and diabetes in the community: do symptom dimensions matter? Results from the Gutenberg Health Study.

    Directory of Open Access Journals (Sweden)

    Jörg Wiltink

    Full Text Available While a bidirectional relationship between diabetes and depression has been established, there is little knowledge if the associations are due to somatic-affective or cognitive-affective dimensions of depression.In a population-based, representative survey of 15.010 participants we therefore studied the associations of the two dimensions of depression with diabetes and health care utilization among depressed and diabetic participants. Depression was assessed by the Patient Health Questionnaire PHQ-9.We found a linear and consistent association between the intensity of depression and the presence of diabetes increasing from 6.9% in no or minimal depression to 7.6% in mild, 9% in moderate and 10.5% in severe depression. There was a strong positive association between somatic-affective symptoms but not with cognitive-affective symptoms and diabetes. Depression and diabetes were both independently related to somatic health care utilisation.Diabetes and depression are associated, and the association is primarily driven by the somatic-affective component of depression. The main limitation of our study pertains to the cross-sectional data acquisition. Further longitudinal work on the relationship of obesity and diabetes should differentiate the somatic and the cognitive symptoms of depression.

    Syzygium cumini (SC) is well known for its anti-diabetic potential, but the mechanism underlying its amelioration of type 2 diabetes is still elusive. Therefore, for the first time, we investigated whether SC aqueous seed extract (100, 200, or 400 mg/kg) exerts any beneficial effects on insulin resistance (IR), serum lipid profile, antioxidant status, and/or pancreatic β-cell damage in high-fat diet / streptozotocin-induced (HFD-STZ) diabetic rats. Wistar albino rats were fed with HFD (55% of calories as fat) during the experiment to induce IR and on the 10th day were injected with STZ (40 mg/kg, i.p.) to develop type 2 diabetes. Subsequently, after confirmation of hyperglycemia on the 14th day (fasting glucose level > 13.89 mM), diabetic rats were treated with SC for the next 21 days. Diabetic rats showed increased serum glucose, insulin, IR, TNF-α, dyslipidemia, and pancreatic thiobarbituric acid-reactive substances with a concomitant decrease in β-cell function and pancreatic superoxide dismutase, catalase, and glutathione peroxidase antioxidant enzyme activities. Microscopic examination of their pancreas revealed pathological changes in islets and β-cells. These alterations reverted to near-normal levels after treatment with SC at 400 mg/kg. Moreover, hepatic tissue demonstrated increased PPARγ and PPARα protein expressions. Thus, our study demonstrated the beneficial effect of SC seed extract on IR and β-cell dysfunction in HFD-STZ-induced type 2 diabetic rats. PMID:22786584

    Male accessory gland inlfammation or infection(MAGI) is a potentially underdiagnosed complication of type2 diabetes(DM2);speciifcally, we reported in a recent study that the frequency of MAGI was 43% among DM2patients. In previous studies, we have demonstrated that diabetic autonomic neuropathy(DAN) is associated with a peculiar ultrasound characterization of the seminal vesicles(SVs) in DM2patients. The aim of the present study was to evaluate the frequency of MAGI in two different categories of DM2patients(i.e.patients with and without symptoms that possibly relfect DAN) and the respective ultrasound characterizations. Sixty DM2patients with a mean(± s.e.m.) age of 42.0±6.0years(range: 34–47years) were classiifed according to the presence or the absence of symptoms that could possibly relfect DAN(groupA: DM2 with symptoms possibly relfecting DAN,n=28patients and groupB: DM2 without symptoms possibly relfecting DAN,n=32patients). The patients in GroupA exhibited a signiifcantly higher frequency of MAGI compared with those in groupB patients(P<0.05); moreover, the GroupA patients exhibited a signiifcantly higher frequency of ultrasound signs suggestive of vesiculitis(P<0.05). Finally, the concentrations of lymphocytes but not the concentrations of the leukocytes in the semen were signiifcantly higher(P<0.05) in groupA compared with groupB.

    Full Text Available Previous studies on healing by gentle touch in clients with various illnesses indicated substantial improvements in psychological well-being, suggesting that this form of treatment might be helpful for people with impaired quality of mental health. The purpose of this study was to evaluate the effectiveness and safety of healing by gentle touch in subjects with self-reported impairments in their psychological well-being or mental health. One hundred and forty-seven clients who identified themselves as having psychological problems received four treatment sessions. Pre- to post-treatment changes in psychological and physical functioning were assessed by self-completed questionnaires which included visual analogue scales (VAS and the EuroQoL (EQ-5D. Participants recorded reductions in stress, anxiety and depression scores and increases in relaxation and ability to cope scores (all P < 0.0004. Improvements were greatest in those with the most severe symptoms initially. This open study provides strong circumstantial evidence that healing by gentle touch is safe and effective in improving psychological well-being in participants with self-reported psychological problems, and also that it safely complements standard medical treatment. Controlled trials are warranted.

    Background Huntington’s disease (HD) is a fatal, inherited neurodegenerative disorder characterized by uncontrollable dance-like movements, as well as cognitive deficits and mood changes. A feature of HD is a metabolic disturbance that precedes neurological symptoms. In addition, brain cholesterol synthesis is significantly reduced, which could hamper synaptic transmission. Objective Alterations in lipid metabolism as a potential target for therapeutic intervention in the R6/2 mouse model of HD were examined. Methods Electrophysiological recordings in vitro examined the acute effects of cholesterol-modifying drugs. In addition, behavioral testing, effects on synaptic activity, and measurements of circulating and brain tissue concentrations of cholesterol and the ketone β-hydroxybutyrate (BHB), were examined in symptomatic R6/2 mice and littermate controls raised on normal chow or a ketogenic diet (KD). Results Whole-cell voltage clamp recordings of striatal medium-sized spiny neurons (MSNs) from symptomatic R6/2 mice showed increased frequency of spontaneous inhibitory postsynaptic currents (sIPSCs) compared with littermate controls. Incubation of slices in cholesterol reduced the frequency of large-amplitude sIPSCs. Addition of BHB or the Liver X Receptor (LXR) agonist T0901317 reduced the frequency and amplitude of sIPSCs. Surprisingly, incubation in simvastatin to reduce cholesterol levels also decreased the frequency of sIPSCs. HD mice fed the KD lost weight more gradually, performed better in an open field, had fewer stereotypies and lower brain levels of cholesterol than mice fed a regular diet. Conclusions Lipid metabolism represents a potential target for therapeutic intervention in HD. Modifying cholesterol or ketone levels acutely in the brain can partially rescue synaptic alterations, and the KD can prevent weight loss and improve some behavioral abnormalities. PMID:27031732

    2009-01-01

    The study has been designed to investigate the effect of benfotiamine and fenofibrate in diabetes-induced experimental vascular endothelial dysfunction (VED) and nephropathy. The single administration of streptozotocin (STZ) (50 mg/kg, i.p.) produced diabetes, which was noted to develop VED and nephropathy in 8 weeks. The diabetes produced VED by attenuating acetylcholine-induced endothelium dependent relaxation, impairing the integrity of vascular endothelium, decreasing serum nitrite/nitrate concentration and increasing serum TBARS and aortic superoxide anion generation. Further, diabetes altered the lipid profile by increasing the serum cholesterol, triglycerides and decreasing the high density lipoprotein. The nephropathy was noted to be developed in the diabetic rat that was assessed in terms of increase in serum creatinine, blood urea, proteinuria, and glomerular damage. The benfotiamine (70 mg/kg, p.o.) and fenofibrate (32 mg/kg, p.o.) or lisinopril (1 mg/kg, p.o., a standard agent) treatments were started in diabetic rats after 1 week of STZ administration and continued for 7 weeks. The treatment with benfotiamine and fenofibrate either alone or in combination attenuated diabetes-induced VED and nephropathy. In addition, the combination of benfotiamine and fenofibrate was noted to be more effective in attenuating the diabetes-induced VED and nephropathy when compared to treatment with either drug alone or lisinopril. Treatment with fenofibrate normalizes the altered lipid profile in diabetic rats, whereas benfotiamine treatment has no effect on lipid alteration in diabetic rats. It may be concluded that diabetes-induced oxidative stress, lipids alteration, and consequent development of VED may be responsible for the induction of nephropathy in diabetic rats. Concurrent administration of benfotiamine and fenofibrate may provide synergistic benefits in preventing the development of diabetes-induced nephropathy by reducing the oxidative stress and lipid

Therefore, it is urgent and necessary to identify natural and safe agents to remedy DN. Timosaponin B-II (TB-II, a major steroidal saponin constituent in Anemarrhena asphodeloides Bunge, exhibits various activities, including anti-inflammatory and hypoglycemic functions. However, the anti-DN effects and potential mechanism(s of TB-II have not been previously reported.Purpose: To investigate the effect of TB-II on DN in alloxan-induced diabetic mice.Methods: TB-II was isolated and purified from A. asphodeloides Bunge using macroporous adsorption resin and preparative high-performance liquid chromatography. The effect of TB-II on DN was evaluated in alloxan-induced diabetic mice using an assay kit and immunohistochemical determination in vivo. The expression of mammalian target of rapamycin (mTOR, thioredoxin-interacting protein (TXNIP, and nuclear transcription factor-κB (NF-κB signaling pathways was also measured using Western blot analysis.Results: TB-II significantly decreased the blood glucose levels and ameliorated renal histopathological injury in alloxan-induced diabetic mice. In addition, TB-II remarkably decreased the levels of renal function biochemical factors, such as kidney index, blood urea nitrogen, serum creatinine, urinary uric acid, urine creatinine, and urine protein, and it reduced lipid metabolism levels of total cholesterol and triglycerides and the levels of inflammatory cytokines interleukin-6 and tumor necrosis factor-α in alloxan-induced mice.

    Full Text Available This study investigated the effects of berberine on amelioration of hyperglycemia and hyperlipidemia and the mechanism involved in high glucose and high fat diet-induced diabetic hamsters. Golden hamsters fed with high glucose and high fat diet were medicated with metformin, simvastatin, and low or high dose of berberine (50 and 100 mg·kg−1 for 6 weeks. The results showed that the body weights were significantly lower in berberine-treated groups than control group. Histological analyses revealed that the treatment of berberine inhibited hepatic fat accumulation. Berberine significantly reduced plasma total cholesterol, triglyceride, free fatty acid, low density lipoprotein cholesterol, malondialdehyde, thiobarbituric acid-reactive substance, and 8-isoprostane level but significantly increased plasma superoxide dismutase activity. Glucose and insulin levels were significantly reduced in metformin and berberine-treated groups. Glucose tolerance tests documented that berberine-treated mice were more glucose tolerant. Berberine treatment increased expression of skeletal muscle glucose transporter 4 mRNA and significantly decreased liver low density lipoprotein receptor mRNA expression. The study suggested that berberine was effective in lowering blood glucose and lipids levels, reducing the body weight, and alleviating the oxidative stress in diabetic hamsters, which might be beneficial in reducing the cardiovascular risk factors in diabetes.

    Runting-stunting syndrome (RSS) in poultry has been known for more than 40 years, but the precise etiology remains unknown and a licensed vaccine is consequently not currently available. In order to mitigate the symptoms associated with RSS, a series of experiments was performed to investigate whether a combined bacteriotherapeutic treatment consisting of probiotics, prebiotics, and organic acids could influence the outcome of this disease. Initially two groups of commercial broiler chickens were either left uninoculated or inoculated with filtrate from homogenized intestines of RSS-affected broiler chickens. One group from each of these two challenge groups was treated, with a bacteriotherapeutic regimen. After 12 days chickens were euthanatized, the body weight was measured, and duodenal lesions were enumerated. Five consecutive broiler chicken flocks were then raised either on litter from RSS-affected birds or on fresh wood shavings. Treatment had no beneficial effect on the number and severity of intestinal lesions. There appeared to be a significant build-up of RSS agent(s) in poultry litter, with each consecutive flock placement, independent of bacteriotherapeutic treatment, as more individuals exhibited intestinal lesions on built-up litter in RSS-affected houses (28.9% vs. 44%). While treatment did not appear to consistently reduce intestinal lesions, it did significantly improve the mean body weights (P<0.05) and uniformity of 12-day-old chickens placed on reused litter in houses in which RSS-infected birds were previously raised. A combination of litter management and bacteriotherapy may be needed to ameliorate the adverse effects of RSS on intestinal health and body weight in broiler chickens. PMID:26473669

Forty male albino rats were used in this study; 10 of them served as a control and 30 rats were injected with a single dose (100 mg/kg) of streptozotocin intraperitoneally. They were subdivided into diabetic, diabetic + ZnONPs (10 mg/kg B.W.), and diabetic and cotreated with ZnONPs + insulin groups. The sperm count and motility were assessed. The activity and mRNA expression of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GRD), and Glutathion-S-Transferase (GST) were determined in the testicular tissue. Malondialdehyde (MDA) and reduced glutathione (GSH) levels were estimated in the testicular tissue. Sperm count and motility increased in ZnONPs treated diabetic rats. A significant increase in the activity and mRNA expression of SOD, CAT, GPx, GRD, and GST was shown in ZnONPs treated diabetic rats. MDA significantly decreased, while GSH increased in testicular tissue of ZnONPs treated diabetic rats. It was concluded that ZnONPs either alone or in combination with insulin have the ability to increase the sperm count and motility and protect the testicular tissue against the oxidative stress induced by diabetes in rats.

    Preeclampsia is one of the most serious pregnancy-related diseases and clinically manifests as hypertension and proteinuria after 20 gestational weeks. The worldwide prevalence is 3-8% of pregnancies, making it the most common cause of maternal and fetal morbidity and mortality. Preeclampsia lacks an effective therapy, and the only "cure" is delivery. We have previously shown that increased synthesis and accumulation of cell-free fetal hemoglobin (HbF) in the placenta is important in the pathophysiology of preeclampsia. Extracellular hemoglobin (Hb) and its metabolites induce oxidative stress, which may lead to acute renal failure and vascular dysfunction seen in preeclampsia. The human endogenous protein, α1-microglobulin (A1M), removes cell-free heme-groups and induces natural tissue repair mechanisms. Exogenously administered A1M has been shown to alleviate the effects of Hb-induced oxidative stress in rat kidneys. Here we attempted to establish an animal model mimicking the human symptoms at stage two of preeclampsia by administering species-specific cell-free HbF starting mid-gestation until term, and evaluated the therapeutic effect of A1M on the induced symptoms. Female pregnant rabbits received HbF infusions i.v. with or without A1M every second day from gestational day 20. The HbF-infused animals developed proteinuria and a significantly increased glomerular sieving coefficient in kidney that was ameliorated by co-administration of A1M. Transmission electron microscopy analysis of kidney and placenta showed both intracellular and extracellular tissue damages after HbF-treatment, while A1M co-administration resulted in a significant reduction of the structural and cellular changes. Neither of the HbF-treated animals displayed any changes in blood pressure during pregnancy. In conclusion, infusion of cell-free HbF in the pregnant rabbits induced tissue damage and organ failure similar to those seen in preeclampsia, and was restored by co-administration of A

    Patients with diabetes mellitus often develop corneal complications and delayed wound healing. How diabetes might alter acute inflammatory responses to tissue injury, leading to delayed wound healing, remains mostly elusive. Using a streptozotocin-induced type I diabetes mellitus mice and corneal epithelium-debridement wound model, we discovered that although wounding induced marked expression of IL-1β and the secreted form of IL-1 receptor antagonist (sIL-1Ra), diabetes suppressed the expressions of sIL-1Ra but not IL-1β in healing epithelia and both in whole cornea. In normoglycemic mice, IL-1β or sIL-1Ra blockade delayed wound healing and influenced each other's expression. In diabetic mice, in addition to delayed reepithelization, diabetes weakened phosphatidylinositol 3-kinase-Akt signaling, caused cell apoptosis, diminished cell proliferation, suppressed neutrophil and natural killer cell infiltrations, and impaired sensory nerve reinnervation in healing mouse corneas. Local administration of recombinant IL-1Ra partially, but significantly, reversed these pathological changes in the diabetic corneas. CXCL10 was a downstream chemokine of IL-1β-IL-1Ra, and exogenous CXCL10 alleviated delayed wound healing in the diabetic, but attenuated it in the normal corneas. In conclusion, the suppressed early innate/inflammatory responses instigated by the imbalance between IL-1β and IL-1Ra is an underlying cause for delayed wound healing in the diabetic corneas. Local application of IL-1Ra accelerates reepithelialization and may be used to treat chronic corneal and potential skin wounds of diabetic patients. PMID:27109611

    Rutin exhibits antidiabetic, antioxidant and anti-inflammatory properties, which makes rutin an attractive candidate for diabetic complications. The present study was designed to investigate the potential effect of rutin on diabetic neuropathy. After induction of diabetic neuropathy, rutin (5mg/kg, 25mg/kg and 50mg/kg) were daily given to the diabetic rats for 2 weeks. At the end of rutin administration, rutin produced a significant inhibition of mechanical hyperalgesia, thermal hyperalgesia and cold allodynia, as well as partial restoration of nerve conduction velocities in diabetic rats. Furthermore, rutin significantly increased Na(+), K(+)-ATPase activities in sciatic nerves and decreased caspase-3 expression in dorsal root ganglions (DRG). In addition, rutin significantly decreased plasma glucose, attenuated oxidative stress and neuroinflammation. Further studies showed that rutin significantly increased hydrogen sulfide (H2S) level, up-regulated the expression of nuclear factor-E2-related factor-2 (Nrf2) and heme oxygenase-1 (HO-1) in DRG. The evidences suggest the beneficial effect of rutin on diabetic neuropathy. Additionally, insulin (2 IU) and BG-12 (15mg/kg) were used to investigate the mechanisms underlying the beneficial effect of rutin on diabetic neuropathy. Insulin achieved lower plasma glucose and BG-12 achieved comparable Nrf2 expression than/to rutin (50mg/kg), respectively. In contrast, the beneficial effect of insulin and BG-12 was inferior to that of rutin (50mg/kg), suggesting that both lowered plasma glucose and Nrf2 signaling contribute to the beneficial effect of rutin on diabetic neuropathy. In conclusion, rutin produces significant protection in diabetic neuropathy, which makes it an attractive candidate for the treatment of diabetic neuropathy.

    Diabetes mellitus is one of the most common causes of neuropathy. Although antioxidant and antidiabetic effects of the aqueous extract of purslane (Portulaca oleracea) (AEOP) have been demonstrated before by other researchers, we did not find any study that assessed the psychobiological effects of AEOP in diabetes induced animals. Thirty ovariectomized (OVX) female Wistar rats were randomly divided into 3 groups of control, Dia and Dia+AEOP. The latter group was orally treated by 300 mg/kg of AEOP for 35 days. Dia and Dia+AEOP groups were made diabetic by IP injection of 60 mg/kg of streptozotocin (STZ). The psychobiological effects of AEOP were assessed by Morris water maze (MWM), elevated plus maze (EPM), forced swimming test (FST) and tail pinch stressor (TPS). AEOP significantly decreased hyperglycemia (pDiabetes significantly decreased their spatial cognitive performance at the training trial as well as the total distance traveled at the probe trial in MWM (pdiabetes related deficits at training trials were improved by AEOP treatment (p0.05). Diabetes significantly increased their non-functional masticatory activity in TPS (p≤0.001) while it was improved in Dia+AEOP group. We showed that AEOP has significant anxiolytic effects and it can improve spatial cognitive performance, locomotor deficit and stress in diabetic OVX rats. PMID:27642327

    We investigated the effects of the oral administration of lophenol (Lo) and cycloartanol (Cy), two kinds of antidiabetic phytosterol isolated from Aloe vera , on glucose and lipid metabolism in Zucker diabetic fatty (ZDF) rats. We demonstrated that the administrations of Lo and Cy suppressed random and fasting glucose levels and reduced visceral fat weights significantly. It was also observed that treatments with Lo and Cy decreased serum and hepatic lipid concentrations (triglyceride, nonesterified fatty acid, and total cholesterol). Additionally, Lo and Cy treatments resulted in a tendency for reduction in serum monocyte chemotactic protein-1 (MCP-1) level and an elevation in serum adiponectin level. Furthermore, the expression levels of hepatic genes encoding gluconeogenic enzymes (G6 Pase, PEPCK), lipogenic enzymes (ACC, FAS), and SREBP-1 were decreased significantly by the administrations of aloe sterols. In contrast, Lo and Cy administration increased mRNA levels of glycolysis enzyme (GK) in the liver. It was also observed that the hepatic β-oxidation enzymes (ACO, CPT1) and PPARα expressions tended to increase in the livers of the Lo- and Cy-treated rats compared with those in ZDF-control rats. We therefore conclude that orally ingested aloe sterols altered the expressions of genes related to glucose and lipid metabolism, and ameliorated obesity-associated metabolic disorders in ZDF rats. These findings suggest that aloe sterols could be beneficial in preventing and improving metabolic disorders with obesity and diabetes in rats. PMID:22352711

    Full Text Available Ethnomedicinally the seeds of Vigna mungo are used as cooling astringent, diet during fever, poultice for abscesses, soap alternative. The increased oxidative stress plays an important role in the etiology and pathogenesis of diabetes mellitus and its various complications. This study was designed to examine the effect of hydroalcoholic extract (VME of V. mungo seeds on STZ-diabetic rats by measuring glycemia, lipid profile, and lipid peroxidation parameters (MDA, PCO, and GSH and antioxidant enzymes activities (SOD, CAT, and GPx. The levels of glucose, TG, TC, MDA, and PCO were increased significantly whereas the levels of serum insulin, reduced glutathione (GSH, superoxide dismutase (SOD, catalase (CAT and Glutathione peroxidise (GPx were decreased in STZ induced diabetic rats. Administration of VME (200 mg/kg bw and 400 mg/kg bw p.o. to diabetic rats for 28 days showed a significant decrease in serum glucose, TG, TC, MDA, and PCO. In addition, we also summarize here that the levels of serum insulin, superoxide dismutase, catalase, GPx, and reduced glutathione (GSH were increased in VME treated diabetic rats. The antioxidant and antihyperglycemic effect of VME was compared with glibenclamide, a well-known antioxidant and antihyperglycemic drug. The findings in this study suggest that the VME possesses a significant favourable effect on antioxidant defense system in addition to its antidiabetic effect. Nonetheless, this study provides evidence that could help explain how the traditional use of V. mungo has been successful in the treatment of various disorders in humans.

    Preclinical Research Trans-resveratrol has a wide range of biological effects that reflect its antioxidant, anti-inflammatory, anticarcinogenic and cardioprotective properties. This study was conducted to elucidate the potential role of resveratrol on hepatic inflammation and the apoptotic pathway components Bcl-2, Bax and p53 in a streptozotocin (STZ)-induced rat model of diabetes mellitus. Inflammatory and apoptotic biomarkers indicated a reduction in hepatic erythropoietin (1.26-fold) and increased asymmetric dimethylarginine (3.9-fold), visfatin (1.6-fold), inflammatory interleukins and TNF-α contents (approximately twofold each) in the diabetic animals. Induction of inducible nitric oxide synthase gene (2.04-fold) and protein expression (1.24-fold) was also observed. Immunohistochemical studies showed enhancement of the apoptotic biomarkers Bax and p53 in diabetic animals. STZ-induced diabetic male Wistar rats were treated with resveratrol (20 mg/kg/day i.p.). Resveratrol succeeded to recover most of these inflammatory and apoptotic elements. Therefore, inflammatory and apoptotic pathways were proved to be affected by STZ-induced diabetes in several aspects and resveratrol might contribute hepatoprotective effects as evidenced from this study.

    Full Text Available Diabetic encephalopathy is one of the severe complications in patients with diabetes mellitus. Findings indicate that saffron extract has antioxidant properties but its underlying beneficial effects on diabetic encephalopathy were unclear. In the present study, the protective activities of saffron were evaluated in diabetic encephalopathy. Saffron at 40 and 80 mg/kg significantly increased body weight and serum TNF-α and decreased blood glucose levels, glycosylated serum proteins, and serum advanced glycation endproducts (AGEs levels. Furthermore, significant increase in HDL and decrease (P<0.05 in cholesterol, triglyceride, and LDL were observed after 28 days of treatment. At the end of experiments, the hippocampus tissue was used for determination of glutathione content (GSH, superoxide dismutase (SOD, and catalase (CAT activities. Furthermore, saffron significantly increased GSH, SOD, and CAT but remarkably decreased cognitive deficit, serum TNF-α, and induced nitric oxide synthase (iNOS activity in hippocampus tissue. Our findings indicated that saffron extract may reduce hyperglycemia and hyperlipidemia risk and also reduce the oxidative stress in diabetic encephalopathy rats. This study suggested that saffron extract might be a promising candidate for the improvement of chemically induced diabetes and its complications.

    Bone marrow-derived mesenchymal stem cells (MSCs) have contributed to the improvement of diabetic nephropathy (DN); however, the actual mediator of this effect and its role has not been characterized thoroughly. We investigated the effects of MSC therapy on DN, focusing on the paracrine effect of renal trophic factors, including exosomes secreted by MSCs. MSCs and MSC-conditioned medium (MSC-CM) as renal trophic factors were administered in parallel to high-fat diet (HFD)-induced type 2 diabetic mice and streptozotocin (STZ)-induced insulin-deficient diabetic mice. Both therapies showed approximately equivalent curative effects, as each inhibited the exacerbation of albuminuria. They also suppressed the excessive infiltration of BMDCs into the kidney by regulating the expression of the adhesion molecule ICAM-1. Proinflammatory cytokine expression (e.g., TNF-α) and fibrosis in tubular interstitium were inhibited. TGF-β1 expression was down-regulated and tight junction protein expression (e.g., ZO-1) was maintained, which sequentially suppressed the epithelial-to-mesenchymal transition of tubular epithelial cells (TECs). Exosomes purified from MSC-CM exerted an anti-apoptotic effect and protected tight junction structure in TECs. The increase of glomerular mesangium substrate was inhibited in HFD-diabetic mice. MSC therapy is a promising tool to prevent DN via the paracrine effect of renal trophic factors including exosomes due to its multifactorial action. PMID:27721418

    Trigonella foenum graecum seed powder (TSP) and sodium orthovanadate (SOV) have been reported to have antidiabetic effects. However, SOV exerts hypoglycemic effects at relatively high doses with several toxic effects. We used low doses of vanadate in combination with TSP and evaluated their antidiabetic effects on antioxidant enzymes and membrane-linked functions in diabetic rat brains. In rats, diabetes was induced by alloxan monohydrate (15 mg/100 g body wt.) and they were treated with 2 IU insulin, 0.6 mg/ml SOV, 5% TSP and a combination of 0.2 mg/ml SOV with 5% TSP for 21 days. Blood glucose levels, activity of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), Na+/K+ ATPase, membrane lipid peroxidation and fluidity were determined in different fractions of whole brain after 21 days of treatment. Diabetic rats showed high blood glucose ( < 0.001), decreased activities of SOD, catalase and Na+/K+ ATPase ( < 0.01, < 0.001 and < 0.01), increased levels of GPx and MDA ( < 0.01 and < 0.001) and decreased membrane fluidity ( < 0.01). Treatment with different antidiabetic compounds restored the above-altered parameters. Combined dose of Trigonella and vanadate was found to be the most effective treatment in normalizing these alterations. Lower doses of vanadate could be used in combination with TSP to effectively counter diabetic alterations without any toxic effects.

    Electric signals from a chest skin electrode can be conducted to the heart and activate contraction. In the present study, normal and diabetic rabbits were stimulated by skin electrode on the abnormal bladder projection area using three levels of exporting voltage (5.84 V, 8.00 V, and 11.00 V). Results demonstrated significantly attenuated electric signals from both groups, in particular the diabetes group. The skin electrode signals were conducted to the bladders, and all vesical signals increased according to strength of stimulating signals from the skin electrode. However, vesical signals from diabetic rabbits were less than those from normal rabbits at the same stimulating strength of exporting voltage. Vesical pressures from the two groups increased along with increased vesical signals, but vesical pressure was less those from diabetic rabbits than in normal rabbits (basic status and different stimulating levels). Linear correlation analysis showed a significantly positive correlation between vesical pressure and signal. These results demonstrated that electric signals from skin electrodes resulted in increased vesical pressure, and vesical pressure increased along with stimulation strength.

    Growth factor receptor-bound protein 10 (Grb10) is an adaptor protein that can negatively regulate the insulin-like growth factor 1 receptor (IGF-1R). The IGF1-1R pathway is critical for cell growth and apoptosis and has been implicated in kidney diseases; however, it is still unknown whether Grb10 expression is up-regulated and plays a role in diabetic nephropathy. Catalpol, a major active ingredient of a traditional Chinese medicine, Rehmannia, has been reported to possess anti-inflammatory and anti-aging activities and then used to treat diabetes. Herein, we aimed to assess the therapeutic effect of catalpol on a mouse model diabetic nephropathy and the potential role of Grb10 in the pathogenesis of this diabetes-associated complication. Our results showed that catalpol treatment improved diabetes-associated impaired renal functions and ameliorated pathological changes in kidneys of diabetic mice. We also found that Grb10 expression was significantly elevated in kidneys of diabetic mice as compared with that in non-diabetic mice, while treatment with catalpol significantly abrogated the elevated Grb10 expression in diabetic kidneys. On the contrary, IGF-1 mRNA levels and IGF-1R phosphorylation were significantly higher in kidneys of catalpol-treated diabetic mice than those in non-treated diabetic mice. Our results suggest that elevated Grb10 expression may play an important role in the pathogenesis of diabetic nephropathy through suppressing IGF-1/IGF-1R signaling pathway, which might be a potential molecular target of catalpol for the treatment of this diabetic complication.

    Nutraceuticals provide health benefits beyond their basic nutrition by modulating a number of biochemical pathways. They are derived from natural products and have gained recognition worldwide as an adjuvant or therapy in the treatment of metabolic disorders such as diabetes. Although the regulation of blood glucose with drugs and insulin greatly reduces the incidence of secondary complications, the need for long-term treatment raises issues of tolerance and affordability. Therefore, the aim of the present study is to explore the nutraceutical potential of Aerva lanata, a herb widely used for its culinary and therapeutic potential in streptozotocin (STZ)-induced diabetic rats. Treatment with 70% ethanolic extract (ALE) at 500 mg per kg b.w per day for 21 days significantly improved the fasting blood glucose (120.33 ± 1.99 mg dL(-1)), insulin level (9.81 ± 0.38 mU L(-1)), HbA1c (7.3 ± 0.36%) and glycogen content in the liver (35.33 ± 1.38 mg g(-1) protein) and muscle (7.67 ± 0.11 mg g(-1) protein) compared to diabetic controls. The extract also showed a significant decrease in blood glucose by 47.29% towards the end of 2 h in oral glucose tolerance test on Day 21. Its therapeutic potential could be partly attributable to the presence of flavonoids, tannins and terpenes (alpha amyrin, betulin and beta sitosterol) along with micronutrients such as potassium, magnesium, calcium and zinc. Hence, we suggest the suitability of Aerva lanata as a nutraceutical for diabetic patients.

  3. Islet-like cell aggregates generated from human adipose tissue derived stem cells ameliorate experimental diabetes in mice.

    Full Text Available BACKGROUND: Type 1 Diabetes Mellitus is caused by auto immune destruction of insulin producing beta cells in the pancreas. Currently available treatments include transplantation of isolated islets from donor pancreas to the patient. However, this method is limited by inadequate means of immuno-suppression to prevent islet rejection and importantly, limited supply of islets for transplantation. Autologous adult stem cells are now considered for cell replacement therapy in diabetes as it has the potential to generate neo-islets which are genetically part of the treated individual. Adopting methods of islet encapsulation in immuno-isolatory devices would eliminate the need for immuno-suppressants. METHODOLOGY/PRINCIPAL FINDINGS: In the present study we explore the potential of human adipose tissue derived adult stem cells (h-ASCs to differentiate into functional islet like cell aggregates (ICAs. Our stage specific differentiation protocol permit the conversion of mesodermic h-ASCs to definitive endoderm (Hnf3β, TCF2 and Sox17 and to PDX1, Ngn3, NeuroD, Pax4 positive pancreatic endoderm which further matures in vitro to secrete insulin. These ICAs are shown to produce human C-peptide in a glucose dependent manner exhibiting in-vitro functionality. Transplantation of mature ICAs, packed in immuno-isolatory biocompatible capsules to STZ induced diabetic mice restored near normoglycemia within 3-4 weeks. The detection of human C-peptide, 1155±165 pM in blood serum of experimental mice demonstrate the efficacy of our differentiation approach. CONCLUSIONS: h-ASC is an ideal population of personal stem cells for cell replacement therapy, given that they are abundant, easily available and autologous in origin. Our findings present evidence that h-ASCs could be induced to differentiate into physiologically competent functional islet like cell aggregates, which may provide as a source of alternative islets for cell replacement therapy in type 1 diabetes.

    We previously demonstrated that impaired glucose-induced insulin secretion (IS) and ATP elevation in islets of Goto-Kakizaki (GK) rats, a nonobese model of diabetes, were significantly restored by 30–60-min suppression of endogenous reactive oxygen species (ROS) overproduction. In this study, we investigated the effect of a longer (12 h) suppression of ROS on metabolism-secretion coupling in β-cells by exposure to tempol, a superoxide (O2 −) dismutase mimic, plus ebselen, a glutathione peroxi...

  5. Correction of Diabetic Hyperglycemia and Amelioration of Metabolic Anomalies by Minicircle DNA Mediated Glucose-Dependent Hepatic Insulin Production.

    Full Text Available Type 1 diabetes mellitus (T1DM is caused by immune destruction of insulin-producing pancreatic β-cells. Commonly used insulin injection therapy does not provide a dynamic blood glucose control to prevent long-term systemic T1DM-associated damages. Donor shortage and the limited long-term success of islet transplants have stimulated the development of novel therapies for T1DM. Gene therapy-based glucose-regulated hepatic insulin production is a promising strategy to treat T1DM. We have developed gene constructs which cause glucose-concentration-dependent human insulin production in liver cells. A novel set of human insulin expression constructs containing a combination of elements to improve gene transcription, mRNA processing, and translation efficiency were generated as minicircle DNA preparations that lack bacterial and viral DNA. Hepatocytes transduced with the new constructs, ex vivo, produced large amounts of glucose-inducible human insulin. In vivo, insulin minicircle DNA (TA1m treated streptozotocin (STZ-diabetic rats demonstrated euglycemia when fasted or fed, ad libitum. Weight loss due to uncontrolled hyperglycemia was reversed in insulin gene treated diabetic rats to normal rate of weight gain, lasting ∼1 month. Intraperitoneal glucose tolerance test (IPGT demonstrated in vivo glucose-responsive changes in insulin levels to correct hyperglycemia within 45 minutes. A single TA1m treatment raised serum albumin levels in diabetic rats to normal and significantly reduced hypertriglyceridemia and hypercholesterolemia. Elevated serum levels of aspartate transaminase, alanine aminotransferase, and alkaline phosphatase were restored to normal or greatly reduced in treated rats, indicating normalization of liver function. Non-viral insulin minicircle DNA-based TA1m mediated glucose-dependent insulin production in liver may represent a safe and promising approach to treat T1DM.

    Full Text Available Pancreatic beta-cell death is known to be the cause of deficient insulin production in diabetes mellitus. Oxidative stress is one of the major causes of beta-cell death. In this study, we investigated the effects of Psoralea corylifolia L. seed (PCS extract on beta-cell death. Oral administration of PCS extract resulted in a significant improvement of hyperglycemia in streptozotocin-induced diabetic mice. PCS extract treatment improved glucose tolerance and increased serum insulin levels. To study the mechanisms involved, we investigated the effects of PCS extract on H2O2-induced apoptosis in INS-1 cells. Treatment with PCS extract inhibited cell death. PCS extract treatment decreased reactive oxygen species level and activated antioxidative enzymes. Among the major components of PCS extract, psoralen and isopsoralen (coumarins, but not bakuchiol, showed preventive effects against H2O2-induced beta-cell death. These findings indicate that PCS extract may be a potential pharmacological agent to protect against pancreatic beta-cell damage caused by oxidative stress associated with diabetes.

    Full Text Available In Korea, soy (Glycine max (L. Merr. leaves are eaten as a seasonal vegetable or pickled in soy sauce. Ethyl acetate extracts of soy leaves (EASL are enriched in pterocarpans and have potent α-glucosidase inhibitory activity. This study investigated the molecular mechanisms underlying the anti-diabetic effect of EASL in C57BL/6J mice with high-fat diet (HFD-induced type 2 diabetes. Mice were randomly divided into normal diet (ND, HFD (60 kcal% fat diet, EASL (HFD with 0.56% (wt/wt EASL, and Pinitol (HFD with 0.15% (wt/wt pinitol groups. Weight gain and abdominal fat accumulation were significantly suppressed by EASL. Levels of plasma glucose, HbA1c, and insulin in the EASL group were significantly lower than those of the HFD group, and the pancreatic islet of the EASL group had greater size than those of the HFD group. EASL group up-regulated neurogenin 3 (Ngn3, paired box 4 (Pax4, and v-maf musculoaponeurotic fibrosarcoma oncogene homolog A (MafA, which are markers of pancreatic cell development, as well as insulin receptor substrate 1 (IRS1, IRS2, and glucose transporter 4 (GLUT4, which are related to insulin sensitivity. Furthermore, EASL suppressed genes involved in hepatic gluconeogenesis and steatosis. These results suggest that EASL improves plasma glucose and insulin levels in mice with HDF-induced type 2 diabetes by regulating β-cell proliferation and insulin sensitivity.

    Naringenin is a flavonoid polyphenolic compound, which facilitates the removal of free radicals, oxidative stress and inflammation. The present study aimed to obtain a better understanding of the effects of curcumin on the regulation of diabetes‑associated cognitive decline, and its underlying mechanisms. An experimental diabetes mellitus (DM) rat model was induced by streptozoticin (50 mg/kg). Following treatment with naringin (100 and 200 mg/kg) for 16 weeks, the body weight and blood glucose levels of the DM rats were measured. A morris water maze test was used to analyze the effects of naringin on the cognitive deficit of the DM rats. The levels of oxidative stress, proinflammatory factors, caspase‑3 and caspase‑9, and the protein expression of peroxisome proliferator‑activated receptor γ (PPARγ) were quantified in the DM rats using a commercially‑available kit and western blot assay, respectively. In addition, a GW9662 PPARγ inhibitor (0.3 mg/kg) was administered to the DM rats to determine whether PPARγ affected the effects of naringin on the cognitive deficit of the DM rats. The results demonstrated that naringin increased the body weight, blood glucose levels, and cognitive deficits of the DM rats. The levels of oxidative stress and proinflammatory factors in the naringin‑treated rats were significantly lower, compared with those of the DM rats. In addition, naringin activated the protein expression of PPARγ, and administration of the PPARγ inhibitor decreased the protein expression of PPARγ, and attenuated the effects of naringin on cognitive deficit. The results also demonstrated that naringin decreased the expression levels of caspase‑3 and caspase‑9 in the DM rats. These results suggested that naringin ameliorated cognitive deficits via oxidative stress, proinflammatory factors and the PPARγ signaling pathway in the type 2 diabetic rat model. Furthermore, oxidative stress, proinflammatory factors and PPARγ signaling may be

    Full Text Available OBJECTIVE: The objective of this study was to determine the risk for the development of high depressive symptoms in study participants with diagnosed and previously undetected diabetes mellitus compared to those without diabetes in a prospective population-based cohort study in Germany. METHODS: We estimated the 5-year cumulative incidence of high depressive symptoms in participants without high depressive symptoms at baseline (n = 3,633, 51.4% men, mean age (SD 59.1 (7.6 years, 7.0% diagnosed diabetes, 5.3% previously undetected diabetes from the population-based Heinz Nixdorf Recall study. Diabetes was assessed by self-report, medication, and blood glucose. High depressive symptoms were assessed using CES-D. We calculated odds ratios and their corresponding 95% confidence interval, using multiple logistic regression analyses. RESULT: Cumulative 5-year incidences (95% CI of high depressive symptoms in participants with diagnosed, undetected, and without diabetes were 7.1 (4.2-10.9, 4.1 (1.8-8.0, and 6.5 (5.6-7.4, respectively. The age-sex-adjusted OR for developing high depressive symptoms was 1.22 (0.74-2.03 in participants with diagnosed compared to those without diabetes, and 1.00 (0.59-1.68 after adjustment for BMI, physical activity, education, stroke, and myocardial infarction. The age-sex adjusted OR for developing high depressive symptoms in participants with previously undetected diabetes compared to those without diabetes was 0.72; 0.35-1.48; and fully adjusted 0.62; 0.30-1.30. CONCLUSION: We found no significant associations, maybe due to low power. However, our results are in line with a recent meta-analysis suggesting that risk of developing high depressive symptoms in patients with diagnosed diabetes may be moderately higher than in those without diabetes, and that comorbidity may explain in part this association. In participants with previously undetected diabetes, this first longitudinal study indicates that the risk is not

OBJETIVO: Determinar as freqüências de diferentes sintomas digestivos em amostra não selecionada de pacientes diabéticos, em comparação às encontradas em pessoas da comunidade. MÉTODOS: A ocorrência de 13 diferentes sintomas digestivos foi investigada por meio da aplicação de um questionário padronizado, especificamente estruturado, em 153 diabéticos dos tipos 1 e 2 e em 50 pessoas aparentemente sadias, tomadas como controles. RESULTADOS: A freqüência de diabéticos com pelo menos um sintoma digestivo foi significativamente superior à verificada no grupo controle (70% vs 36%, p = 0,01. Freqüências elevadas de plenitude gástrica (30% vs 36%, pirose (30% vs 34% e de constipação (17% vs 12%, foram observadas tanto entre os diabéticos como nos controles. No entanto, somente a freqüência de um único sintoma, a disfagia, foi significativamente maior entre os diabéticos, em relação ao grupo controle (13% vs 2%, p = 0,02. CONCLUSÃO: Estes resultados indicam que a freqüência de sintomas digestivos em diabéticos, apesar de elevada, não difere da verificada na população geral, exceto para a disfagia. As freqüências dos diferentes sintomas estiveram próximas das faixas relatadas em estudos do hemisfério Norte, o que não apóia a hipótese de que fatores inerentes ao meio afetam a ocorrência de queixas digestivas em diabéticos.PURPOSE: To determine the frequencies of digestive symptoms in an unselected sample of Brazilian diabetics, in comparison to those verified in the general population.

    Background Circulating endothelial progenitors cells (EPCs) play a critical role in neovascularization and endothelial repair. There is a growing evidence that hyperglycemia related to Diabetes Mellitus (DM) decreases EPC number and function so promoting vascular complications. Aim of the Study This study investigated whether an intensive glycemic control regimen in Type 2 DM can increase the number of EPCs and restores their function. Methods Sixty-two patients with Type 2 DM were studied. Patients were tested at baseline and after 3 months of an intensive regimen of glycemic control. The Type 2 DM group was compared to control group of subjects without diabetes. Patients with Type 2 DM (mean age 58.2±5.4 years, 25.6% women, disease duration of 15.4±6.3 years) had a baseline HgA1c of 8.7±0.5% and lower EPC levels (CD34+/KDR+) in comparison to healthy controls (p<0.01). Results The intensive glycemic control regimen (HgA1c decreased to 6.2±0.3%) was coupled with a significant increase of EPC levels (mean of 18%, p<0.04 vs. baseline) and number of EPCs CFUs (p<0.05 vs. baseline). Conclusion This study confirms that number and bioactivity of EPCs are reduced in patients with Type 2 DM and, most importantly, that the intensive glycemic control in Type 2 DM promotes EPC improvement both in their number and in bioactivity.

    2014-09-01

    Full Text Available Emerging evidence suggests that diabetes affects cognitive function and increases the incidence of dementia. However, the mechanisms by which diabetes modifies cognitive function still remains unclear. Morphologically, diabetes is associated with neuronal loss in the frontal and temporal lobes including the hippocampus, and aberrant functional connectivity of the posterior cingulate cortex and medial frontal/temporal gyrus. Clinically, diabetic patients show decreased executive function, information processing, planning, visuospatial construction, and visual memory. Therefore, in comparison with the characteristics of AD brain structure and cognition, diabetes seems to affect cognitive function through not only simple AD pathological feature-dependent mechanisms, but also independent mechanisms. As an Abeta/tau-independent mechanism, diabetes compromises cerebrovascular function, increases subcortical infarction and might alter the blood brain barrier (BBB. Diabetes also affects glucose metabolism, insulin signaling and mitochondrial function in the brain. Diabetes also modifies metabolism of Abeta and tau and causes Abeta/tau-dependent pathological changes. Moreover, there is evidence that suggests an interaction between Abeta/tau-dependent and independent mechanisms. Therefore, diabetes modifies cognitive function through Abeta/tau-dependent and independent mechanisms. Interaction between these two mechanisms forms a vicious cycle.

    Diabetes mellitus (DM) is caused by either destruction of pancreatic β-cells (type 1 DM) or unresponsiveness to insulin (type 2 DM). Conventional therapies for diabetes mellitus have been developed but still needs improvement. Many diabetic patients have complemented conventional therapy with alternative methods including oral supplementation of natural products. In this study, we assessed whether Ginkgo biloba extract (EGb) 761 could provide beneficial effects in the streptozotocin-induced type 1 DM and high-fat diet-induced type 2 DM murine model system. For the type 1 DM model, streptozotocin-induced mice were orally administered EGb 761 for 10 days prior to streptozotocin injection and then again administered EGb 761 for an additional 10 days. Streptozotocin-treated mice administered EGb 761 exhibited lower blood triglyceride levels, lower blood glucose levels and higher blood insulin levels compared to streptozotocin-treated mice. Furthermore, liver LPL and liver PPAR-α were increased whereas IL-1β and TNF-α were decreased in streptozotocin-injected mice treated with EGb 761 compared to mice injected with streptozotocin alone. For the type 2 DM model, mice were given high-fat diet for 60 days and then orally administered EGb 761 every other day for 80 days. We found that mice given a high-fat diet and EGb 761 showed decreased blood triglyceride levels, increased liver LPL, increased liver PPAR-α and decreased body weight compared to mice given high-fat diet alone. These results suggest that EGb 761 can exert protective effects in both type 1 and type 2 DM murine models.

    Full Text Available Aim. The objective of this study was to analyze the changes in depressive and extrapyramidal symptomatology during glycine augmentation of antipsychotic treatment in patients with schizophrenia.Materials and methods. Twenty-nine schizophrenic patients (ICD-10 with predominant negative symptoms in stable mental state participated in a 10-week open-label prospective study. Patients received stable doses of antipsychotic drugs for at least 3 months before glycine application. During the next 6 weeks patients received augmentation of antipsychotic treatment with glycine (up to 60 g per day. The first and last two weeks of observation were used to assess stability of mental state. Symptom severity was assessed using the Hamilton Depression Rating Scale (HDRS, the Positive and Negative Syndrome Scale (PANSS, and the Simpson-Angus Extrapyramidal Symptom Rating Scale (SASResults. In the studied group after 6 weeks of administration of glycine a significant improvement in depressive symptoms (reduced scores by 25.8% in HDRS, p <0.001 and reduced scoring in mood symptoms of PANSS were observed. In SAS a reduction of extrapyramidal symptoms’ severity (p <0.05 was also noted. Two weeks after the glycine augmentation the symptom severity in the HDRS, PANSS, and SAS remained at similar levels.Conclusions. Glycine augmentation of antipsychotic treatment may reduce the severity of depressive and extrapyramidal symptoms. Glycine use was safe and well tolerated.

  4. D-Saccharic acid 1,4-lactone protects diabetic rat kidney by ameliorating hyperglycemia-mediated oxidative stress and renal inflammatory cytokines via NF-κB and PKC signaling

    International Nuclear Information System (INIS)

    Increasing evidence suggests that oxidative stress is involved in the pathogenesis of diabetic nephropathy (DN) and this can be attenuated by antioxidants. D-Saccharic acid 1,4-lactone (DSL) is known for its detoxifying and antioxidant properties. Our early investigation showed that DSL can ameliorate alloxan (ALX) induced diabetes mellitus and oxidative stress in rats by inhibiting pancreatic β-cell apoptosis. In the present study we, therefore, investigated the protective role of DSL against renal injury in ALX induced diabetic rats. ALX exposure (at a dose of 120 mg/kg body weight, i. p., once) elevated the blood glucose level, serum markers related to renal injury, the production of reactive oxygen species (ROS), and disturbed the intra-cellular antioxidant machineries. Oral administration of DSL (80 mg/kg body weight) restored all these alterations close to normal. In addition, DSL could also normalize the aldose reductase activity which was found to increase in the diabetic rats. Investigating the mechanism of its protective activity, we observed the activation of different isoforms of PKC along with the accumulation of matrix proteins like collagen and fibronectin. The diabetic rats also showed nuclear translocation of NF-κB and increase in the concentration of inflammatory cytokines in the renal tissue. The activation of mitochondria dependent apoptotic pathway was observed in the diabetic rat kidneys. However, treatment of diabetic rats with DSL counteracted all these changes. These findings, for the first time, demonstrated that DSL could ameliorate renal dysfunction in diabetic rats by suppressing the oxidative stress related signalling pathways. - Highlights: ► Sustained hyperglycemia and oxidative stress lead to diabetic renal injury. ► D-saccharic acid 1,4-lactone prevents renal damage in alloxan-induced diabetes. ► It restores intra-cellular antioxidant machineries and kidney apoptosis. ► DSL reduces hyperglycemia-mediated oxidative stress

    Full Text Available The aim of the study was to assess the level of anxiety and depressiveness in patients who had qualified for hyperbaric oxygen therapy (HBOT for the treatment of ulcerative lesions in the lower limbs, occurring as a result of diabetic foot syndrome (DFS,. A total of 50 patients with type 2 diabetes and diabetic foot syndrome were enrolled to the study. All patients have received 30 sessions of HBOT. During the therapy blood glucose was measured and photographic documentation was carried out. All patients underwent the following procedures: medical history and socioeconomic interview, psychiatric examination, self-report and objective psychometric tests to measure anxiety and depressiveness. Based on the obtained results, we reported that patients with a greater degree of tissue damage had higher levels of depressive symptoms in the self-report tests as well as in the objective evaluation of the investigator. In terms of location of ulcerative lesions - the level of depressiveness was greater when the affected area included toes, and the level of anxiety was increased when it concerned the heel. Regarding other parameters, statistically significant correlations were not observed.

    Disruption of copper homeostasis has been implicated in Alzheimer's disease (AD) during the last 2 decades; however, whether copper is a friend or a foe is controversial. Within a genetically tractable Drosophila AD model, we manipulated the expression of human high-affinity copper importer orthologous in Drosophila to explore the in vivo roles of copper ions in the development of AD. We found that inhibition of Ctr1C expression by RNAi in Aβ-expressing flies significantly reduced copper accumulation in the brains of the flies as well as ameliorating neurodegeneration, enhancing climbing ability, and prolonging lifespan. Interestingly, Ctr1C inhibition led to a significant increase in higher-molecular-weight Aβ42 forms in brain lysates, whereas it was accompanied by a trend of decreased expression of amyloid-β degradation proteases (including NEP1-3 and IDE) with age and reduced Cu-Aβ interaction-induced oxidative stress in Ctr1C RNAi flies. Similar results were obtained from inhibiting another copper importer Ctr1B and overexpressing a copper exporter DmATP7 in the nervous system of AD flies. These results imply that copper may play a causative role in developing AD, as either Aβ oligomers or aggregates were less toxic in a reduced copper environment or one with less copper binding. Early manipulation of brain copper uptake can have a great effect on Aβ pathology.

    Full Text Available This study analyzed the prevalence of and association between symptoms of eating disorders and depression in female and male emerging adults with early-onset, long-duration type 1 diabetes and investigated how these symptoms are associated with metabolic control.In a nationwide population-based survey, 211 type 1 diabetes patients aged 18-21 years completed standardized questionnaires, including the SCOFF questionnaire for eating disorder symptoms and the Patient Health Questionnaire (PHQ-9 for symptoms of depression and severity of depressive symptoms (PHQ-9 score. Multiple linear and logistic regression models were used to analyze the association between eating disorder and depressive symptoms and their associations with HbA1c.A total of 30.2% of the women and 9.5% of the men were screening positive for eating disorders. The mean PHQ-9 score (standard deviation was 5.3 (4.4 among women and 3.9 (3.6 among men. Screening positive for an eating disorder was associated with more severe depressive symptoms among women (βwomen 3.8, p<0.001. However, neither eating disorder symptoms nor severity of depressive symptoms were associated with HbA1c among women, while HbA1c increased with the severity of depressive symptoms among men (βmen 0.14, p=0.006.Because of the high prevalence of eating disorder and depressive symptoms, their interrelationship, and their associations with metabolic control, particularly among men, regular mental health screening is recommended for young adults with type 1 diabetes.

    We hypothesize that in patients with insulin-dependent diabetes mellitus (IDDM), recent antecedent iatrogenic hypoglycemia is a major cause of hypoglycemia-associated autonomic failure, a disorder distinct from classical diabetic autonomic neuropathy (CDAN), and that hypoglycemia-associated autonomic failure, by reducing both symptoms of and defense against developing hypoglycemia, results in recurrent iatrogenic hypoglycemia, thus creating a vicious cycle.

    Neuronal injury following blast-induced traumatic brain injury (bTBI) increases the risk for neuropsychiatric disorders, yet the pathophysiology remains poorly understood. Blood-brain-barrier (BBB) disruption, endoplasmic reticulum (ER) stress, and apoptosis have all been implicated in bTBI. Microvessel compromise is a primary effect of bTBI and is postulated to cause subcellular secondary effects such as ER stress. What remains unclear is how these secondary effects progress to personality disorders in humans exposed to head trauma. To investigate this we exposed male rats to a clinically relevant bTBI model we have recently developed. The study examined initial BBB disruption using Evan's blue (EB), ER stress mechanisms, apoptosis and impulsive-like behavior measured with elevated plus maze (EPM). Large BBB openings were observed immediately following bTBI, and persisted for at least 6 h. Data showed increased mRNA abundance of stress response genes at 3 h, with subsequent increases in the ER stress markers C/EBP homologous protein (CHOP) and growth arrest and DNA damage-inducible protein 34 (GADD34) at 24 h. Caspase-12 and Caspase-3 were both cleaved at 24 h following bTBI. The ER stress inhibitor, salubrinal (SAL), was administered (1 mg/kg i.p.) to investigate its effects on neuronal injury and impulsive-like behavior associated with bTBI. SAL reduced CHOP protein expression, and diminished Caspase-3 cleavage, suggesting apoptosis attenuation. Interestingly, SAL also ameliorated impulsive-like behavior indicative of head trauma. These results suggest SAL plays a role in apoptosis regulation and the pathology of chronic disease. These observations provide evidence that bTBI involves ER stress and that the unfolded protein response (UPR) is a promising molecular target for the attenuation of neuronal injury. PMID:25540611

  16. D-saccharic acid-1,4-lactone ameliorates alloxan-induced diabetes mellitus and oxidative stress in rats through inhibiting pancreatic beta-cells from apoptosis via mitochondrial dependent pathway

    International Nuclear Information System (INIS)

    Oxidative stress plays a vital role in diabetic complications. To suppress the oxidative stress mediated damage in diabetic pathophysiology, a special focus has been given on naturally occurring antioxidants present in normal diet. D-saccharic acid 1,4-lactone (DSL), a derivative of D-glucaric acid, is present in many dietary plants and is known for its detoxifying and antioxidant properties. The aim of the present study was to evaluate the beneficial role of DSL against alloxan (ALX) induced diabetes in the pancreas tissue of Swiss albino rats. A dose-dependent study for DSL (20–120 mg/kg body weight) was carried out to find the effective dose of the compound in ALX-induced diabetic rats. ALX exposure elevated the blood glucose, glycosylated Hb, decreased the plasma insulin and disturbed the intra-cellular antioxidant machineries whereas oral administration of DSL at a dose of 80 mg/kg body weight restored these alterations close to normal. Investigating the mechanism of the protective activity of DSL we observed that it prevented the pancreatic β-cell apoptosis via mitochondria-dependent pathway. Results showed decreased mitochondrial membrane potential, enhanced cytochrome c release in the cytosol and reciprocal regulation of Bcl-2 family proteins in the diabetic rats. These events were also found to be associated with increased level of Apaf-1, caspase 9, and caspase 3 that ultimately led to pancreatic β-cell apoptosis. DSL treatment, however, counteracted these changes. In conclusion, DSL possesses the capability of ameliorating the oxidative stress in ALX-induced diabetes and thus could be a promising approach in lessening diabetic complications. Highlights: ► Oxidative stress is suggested as a key event in the pathogenesis of diabetes. ► D-saccharic acid 1,4-lactone (DSL) reduces the alloxan-induced diabetes mellitus. ► DSL normalizes cellular antioxidant machineries disturbed due to alloxan toxicity. ► DSL inhibits pancreatic β-cells apoptosis

  8. Taurine exerts hypoglycemic effect in alloxan-induced diabetic rats, improves insulin-mediated glucose transport signaling pathway in heart and ameliorates cardiac oxidative stress and apoptosis

    International Nuclear Information System (INIS)

    Hyperlipidemia, inflammation and altered antioxidant profiles are the usual complications in diabetes mellitus. In the present study, we investigated the therapeutic potential of taurine in diabetes associated cardiac complications using a rat model. Rats were made diabetic by alloxan (ALX) (single i.p. dose of 120 mg/kg body weight) and left untreated or treated with taurine (1% w/v, orally, in water) for three weeks either from the day of ALX exposure or after the onset of diabetes. Animals were euthanized after three weeks. ALX-induced diabetes decreased body weight, increased glucose level, decreased insulin content, enhanced the levels of cardiac damage markers and altered lipid profile in the plasma. Moreover, it increased oxidative stress (decreased antioxidant enzyme activities and GSH/GSSG ratio, increased xanthine oxidase enzyme activity, lipid peroxidation, protein carbonylation and ROS generation) and enhanced the proinflammatory cytokines levels, activity of myeloperoxidase and nuclear translocation of NFκB in the cardiac tissue of the experimental animals. Taurine treatment could, however, result to a decrease in the elevated blood glucose and proinflammatory cytokine levels, diabetes-evoked oxidative stress, lipid profiles and NFκB translocation. In addition, taurine increased GLUT 4 translocation to the cardiac membrane by enhanced phosphorylation of IR and IRS1 at tyrosine and Akt at serine residue in the heart. Results also suggest that taurine could protect cardiac tissue from ALX induced apoptosis via the regulation of Bcl2 family and caspase 9/3 proteins. Taken together, taurine supplementation in regular diet could play a beneficial role in regulating diabetes and its associated complications in the heart. Highlights: ► Taurine controls blood glucose via protection of pancreatic β cells in diabetic rat. ► Taurine controls blood glucose via increasing the insulin level in diabetic rat. ► Taurine improves cardiac AKT/GLUT4 signaling

    Full Text Available The aim of this study was to determine the effects of balanced deep-sea water (BDSW on hyperglycemia and glucose intolerance in streptozotocin (STZ-induced diabetic mice. BDSW was prepared by mixing DSW mineral extracts and desalinated water to yield a final hardness of 1000-4000 ppm. Male ICR mice were assigned to 6 groups; mice in each group were given tap water (normal and STZ diabetic groups or STZ with BDSW of varying hardness (0, 1000, 2000, and 4000 ppm for 4 weeks. The STZ with BDSW group exhibited lowered fasting plasma glucose levels than the STZ-induced diabetic group. Oral glucose tolerance tests showed that BDSW improves impaired glucose tolerance in STZ-induced diabetic mice. Histopathological evaluation of the pancreas showed that BDSW restores the morphology of the pancreatic islets of Langerhans and increases the secretion of insulin in STZ-induced diabetic mice. Quantitative real-time PCR assay revealed that the expression of hepatic genes involved in gluconeogenesis, glucose oxidation, and glycogenolysis was suppressed, while the expression of the genes involved in glucose uptake, β-oxidation, and glucose oxidation in muscle were increased in the STZ with BDSW group. BDSW stimulated PI3-K, AMPK, and mTOR pathway-mediated glucose uptake in C2C12 myotubes. BDSW increased AMPK phosphorylation in C2C12 myotubes and improved impaired AMPK phosphorylation in the muscles of STZ-induced diabetic mice. Taken together, these results suggest that BDSW is a potential anti-diabetic agent, owing to its ability to suppress hyperglycemia and improve glucose intolerance by modulating glucose metabolism, recovering pancreatic islets of Langerhans and increasing glucose uptake.

    A dominance of Th2 cytokine pattern is associated with allergic diseases, whereas a Th1 pattern has been reported in autoimmune type 1 diabetes (T1D). The Th1/Th2 paradigm has led to the interest in the relationship between these diseases. To investigate the association between atopic diseases, asthma and occurrence of T1D-related β-cell autoantibodies in children, we studied 7208 unselected 2.5-yr-old children from the All Babies in Southeast Sweden (ABIS) cohort. The ABIS cohort includes 17 055 (78.3% out of all 21 700) children born from October 1997 to October 1999, and followed prospectively with regular biological samples and questionnaires, at birth, at 1 and 2.5 yr. Risk factors for development of β-cell autoantibodies at the age of 2.5 yr were type of domiciliary, domestic animals (cat and dog) and getting a new brother/sister during first year of life. Maternal smoking during pregnancy [odds ratio (OR) 1.6] and heavy smoking at home (>10 vs. ≤10 cigarettes) implied risk for tyrosine phosphatase autoantibodies (IA-2A) (OR 2.9). Wheezing during the first year of life implied risk for glutamic acid decarboxylase autoantibodies (GADA) (OR 1.9) and double positivity for GADA and IA-2A (OR 9.1). Rash on several locations (at least three times during 12 months) (OR 1.7) as well as allergic symptoms related to fur-bearing animals (OR 2.7) implied risk for IA-2A. Food allergy against egg, cow-milk, fish, nuts/almonds (one or in combination) implied risk for GADA and IA-2A (OR 4.5). In a regression model wheezing during first year of life remained as a risk factor for GADA [OR 2.0, confidence interval (CI) 1.1-3.8; p = 0.031] and both GADA and IA-2A (OR 10.7, CI 3.9-29.4; p = 0.000). We conclude that allergic symptoms are associated with the development of T1D-related autoantibodies during the first years of life.

    Full Text Available Depletion of interstitial cells of Cajal (ICC is certified in the stomach of diabetic patients. Though electroacupuncture (EA at ST36 is an effective therapy to regulate gastric motility, the mechanisms of EA at ST36 on gastric emptying and networks of ICC remain to be elucidated. The aims of this study were to investigate the effects of EA on gastric emptying and on the alterations of ICC networks. Rats were randomized into the control, diabetic rats (DM, diabetic rats with sham EA (DM+SEA, diabetic rats with low frequency EA (DM+LEA and diabetic rats with high frequency EA groups (DM+HEA. The expression of c-kit in each layer of gastric wall was assessed by western blotting. The proliferation of ICC was identified by immunolabeling of c-kit and Ki67 as the apoptosis of ICC was examined by TUNEL staining. The results were as follows: (1 Gastric emptying was severely delayed in the DM group, but accelerated in the LEA and HEA group, especially in the LEA group. (2 The expression of c-kit in each layer was reduced apparently in the DM group, but also up-regulated in the LEA and HEA group. (3 Plentiful proliferated ICC (c-kit+/Ki67+ forming bushy networks with c-kit+ cells were observed in the LEA and HEA group, while the apoptotic cells (c-kit+/TUNEL+ were hardly captured in the LEA and HEA group. Collectively, low and high frequency EA at ST36 rescue the damaged networks of ICC by inhibiting the apoptosis and enhancing the proliferation in the stomach of diabetic rats, resulting in an improved gastric emptying.

    Diabetic nephropathy (DN) is the leading cause of end-stage renal failure and is characterized by excessive deposition of extracellular matrix (ECM) proteins such as fibronectin (FN), in the glomerular mesangium and tubulointerstitium. Betulinic acid (BA), a pentacyclic triterpene derived from the bark of the white birch tree, has been demonstrated to have many pharmacological activities. However, the effect of BA on DN has not been fully elucidated. To explore the possible anti-inflammatory effects of BA and their underlying mechanisms, we used streptozotocin-induced diabetic rat kidneys and high glucose-treated glomerular mesangial cells. Our study showed BA could inhibit the degradation of IκBα and the activity of NF-κB in diabetic rat kidneys and high glucose-induced mesangial cells, resulting in reduction of FN expression. In addition, BA suppressed the DNA binding activity and transcriptional activity of NF-κB in high glucose-induced glomerular mesangial cells (GMCs). Furthermore, BA enhanced the interaction between IκBα and β-arrestin2 in mesangial cells. Taken together, our data suggest BA inhibits NF-κB activation through stabilizing NF-κB inhibitory protein IκBα, thereby preventing diabetic renal fibrosis. PMID:27364889

    Moringa oleifera Lam. contains many active ingredients with nutritional and medicinal values. It is commonly used in folk medicine as an antidiabetic agent. The present study was designed to investigate how an aqueous extract from the leaves of M. oleifera reveals hypoglycemia in diabetic rats. M. oleifera leaf extract counteracted the alloxan-induced diabetic effects in rats as it normalized the elevated serum levels of glucose, triglycerides, cholesterol, and malondialdehyde, and normalized mRNA expression of the gluconeogenic enzyme pyruvate carboxylase in hepatic tissues. It also increased live body weight gain and normalized the reduced mRNA expression of fatty acid synthase in the liver of diabetic rats. Moreover, it restored the normal histological structure of the liver and pancreas damaged by alloxan in diabetic rats. This study revealed that the aqueous extract of M. oleifera leaves possesses potent hypoglycemic effects through the normalization of elevated hepatic pyruvate carboxylase enzyme and regeneration of damaged hepatocytes and pancreatic β cells via its antioxidant properties.

    Obesity is one of the major factors to increase various disorders like diabetes. The present paper emphasizes study related to the antiobesity effect of Phalaris canariensis seeds hexane extract (Al-H) in high-fat diet- (HFD-) induced obese CD1 mice and in streptozotocin-induced mild diabetic (MD) and severely diabetic (SD) mice.AL-H was orally administered to MD and SD mice at a dose of 400 mg/kg once a day for 30 days, and a set of biochemical parameters were studied: glucose, cholesterol, triglycerides, lipid peroxidation, liver and muscle glycogen, ALP, SGOT, SGPT, glucose-6-phosphatase, glucokinase, hexokinase, SOD, CAT, GSH, GPX activities, and the effect on insulin level. HS-H significantly reduced the intake of food and water and body weight loss as well as levels of blood glucose, serum cholesterol, triglyceride, lipoprotein, oxidative stress, showed a protective hepatic effect, and increased HDL-cholesterol, serum insulin in diabetic mice. The mice fed on the high-fat diet and treated with AL-H showed inhibitory activity on the lipid metabolism decreasing body weight and weight of the liver and visceral adipose tissues and cholesterol and triglycerides in the liver. We conclude that AL-H can efficiently reduce serum glucose and inhibit insulin resistance, lipid abnormalities, and oxidative stress in MD and SD mice. Our results demonstrate an antiobesity effect reducing lipid droplet accumulation in the liver, indicating that its therapeutic properties may be due to the interaction plant components soluble in the hexane extract, with any of the multiple targets involved in obesity and diabetes pathogenesis.

    Full Text Available A number of potential anti-diabetic plants were identified through an ethnobotanical survey of the traditional pharmacopeia of the Cree of Eeyou Istchee (CEI—Northeastern Canada used against symptoms of diabetes and their biological activity assessed by in vitro bioassays. Among these, Sorbus decora C.K.Schneid. (Rosacea ranked highly and increased the transport of glucose in skeletal muscle cells in culture. The present study thus aimed at confirming the antidiabetic potential of S. decora in in vivo models of insulin resistance and diabetes, notably the streptozotocin Type 1 diabetic rat (STZ, the genetic KK-Ay Type 2 diabetic mouse and the rat rendered insulin resistant with 10% glucose water consumption for 6 weeks. Sorbus decora ethanolic crude extract (SDEE was administered orally (200 mg kg-1 and compared to metformin (150 or 500 mg kg-1. The intragastric (i.g. gavage of SDEE transiently decreased glycemia in STZ rats in a bi-phasic manner but the effect was cumulative over several days. In KK-Ay mice, SDEE incorporated in food (0.12% decreased glycemia by 15% within 1 week as compared to vehicle controls. In pre-diabetic insulin-resistant rats, SDEE fed daily by i.g. gavage for 2 weeks significantly decreased the slight hyperglycemia and hyperinsulinemia, without affecting sugar water intake. Using the HOMA insulin resistance parameter, the effect of SDEE was equivalent to that of metformin. In conclusion, the ethanolic crude extract of S. decora demonstrates both anti-hyperglycemic and insulin-sensitizing activity in vivo, thereby confirming anti-diabetic potential and validating CEI traditional medicine.

    Full Text Available Oxidative stress plays an important role in pathogenesis of diabetes mellitus and its complications. Our previous study has shown glucose lowering effect produced by 3 months supplementation of Nigella sativa (NS in combination with oral hypoglycemic drugs among type 2 diabetics. This study explored the long term glucose lowering effect (over one year of NS in patients with type 2 diabetes mellitus on oral hypoglycemic drugs and to study its effect on redox status of such patients.114 type 2 diabetic patients on standard oral hypoglycemic drugs were assigned into 2 groups by convenience. The control group (n = 57 received activated charcoal as placebo and NS group (n = 57 received 2g NS, daily, for one year in addition to their standard medications. Fasting blood glucose (FBG, glycosylated hemoglobin (HbA1c, C- peptide, total antioxidant capacity (TAC, superoxide dismutase (SOD, catalase (CAT, glutathione and thiobarbituric acid reactive substances (TBARS at the baseline, and every 3 months thereafter were determined. Insulin resistance and β-cell activity were calculated using HOMA 2 calculator.Comparison between the two groups showed a significant drop in FBG (from 180 ± 5.75 to 180 ± 5.59 in control Vs from 195 ± 6.57 to 172 ± 5.83 in NS group, HbA1c (from 8.2 ± 0.12 to 8.5 ± 0.14 in control VS from 8.6 ± 0.13 to 8.2 ± 0.14 in NS group, and TBARS (from 48.3 ± 6.89 to 52.9 ± 5.82 in control VS from 54.1 ± 4.64 to 41.9 ± 3.16 in NS group, in addition to a significant elevation in TAC, SOD and glutathione in NS patients compared to controls. In NS group, insulin resistance was significantly lower, while β-cell activity was significantly higher than the baseline values during the whole treatment period.Long term supplementation with Nigella sativa improves glucose homeostasis and enhances antioxidant defense system in type 2 diabetic patients treated with oral hypoglycemic drugs.Clinical Trials Registry-India (CTRI CTRI/2013/06/003781.

    Diabetes mellitus substantially increases the risk of stroke and enhances brain's vulnerability to ischemia insult. In a previous study, Chikusetsu saponin IVa (CHS) pretreatment was proved to protect the brain from cerebral ischemic in normal stroke models. Whether CHS could attenuate cerebral ischemia/reperfusion (I/R) injury in diabetic mice and the possible underlying mechanism are still unrevealed. Male C57BL/6 mice were injected streptozotocin to induce diabetes. After that, the mice were pretreated with CHS for 1 month, and then, focal cerebral ischemia was induced following 24-h reperfusion. The neurobehavioral scores, infarction volumes, and some cytokines in the brain were measured. Apoptosis was analyzed by caspase-3, Bax, and Bcl-2 expression. Downstream molecules of adiponectin (APN) were investigated by Western blotting. The results showed that CHS reduced infarct size, improved neurological outcomes, and inhibited cell injury after I/R. In addition, CHS pretreatment increased APN level and enhanced neuronal AdipoR1, adenosine monophosphate-activated protein kinase (AMPK), and glycogen synthase kinase 3 beta (GSK-3β) expression in a concentration-dependent manner in diabetic mice, and these effects were abolished by APN knockout (KO). In vitro test, CHS treatment also alleviated PC12 cell injury and apoptosis, evidenced by reduced tumor necrosis factor alpha (TNF-α), malondialdehyde (MDA) and caspase-3 expression, and Bax/Bcl-2 ratio in I/R injured cells. Moreover, CHS enhanced AdipoR1, AMPK, and GSK-3β expression in a concentration-dependent manner. Likewise, short interfering RNA (sinRNA) knockdown of liver kinase B1 (LKB1), an upstream kinase of AMPK, reduced the ability of CHS in protecting cells from I/R injury. Furthermore, this LKB1-dependent cellular protection resulted from AdipoR1 and APN activation, as supported by the experiment using sinRNA knockdown of AdipoR1 and APN. Thus, CHS protected brain I/R in diabetes through AMPK

    Tiliroside contained in several dietary plants, such as rose hips, strawberry and raspberry, is a glycosidic flavonoid and possesses anti-inflammatory, antioxidant, anticarcinogenic and hepatoprotective activities. Recently, it has been reported that the administration of tiliroside significantly inhibited body weight gain and visceral fat accumulation in normal mice. In this study, we evaluated the effects of tiliroside on obesity-induced metabolic disorders in obese-diabetic KK-A(y) mice. In KK-A(y) mice, the administration of tiliroside (100 mg/kg body weight/day) for 21 days failed to suppress body weight gain and visceral fat accumulation. Although tiliroside did not affect oxygen consumption, respiratory exchange ratio was significantly decreased in mice treated with tiliroside. In the analysis of metabolic characteristics, it was shown that plasma insulin, free fatty acid and triglyceride levels were decreased, and plasma adiponectin levels were increased in mice administered tiliroside. The messenger RNA expression levels of hepatic adiponectin receptor (AdipoR)-1 and AdipoR2 and skeletal muscular AdipoR1 were up-regulated by tiliroside treatment. Furthermore, it was indicated that tiliroside treatment activated AMP-activated protein kinase in both the liver and skeletal muscle and peroxisome proliferator-activated receptor α in the liver. Finally, tiliroside inhibited obesity-induced hepatic and muscular triglyceride accumulation. These findings suggest that tiliroside enhances fatty acid oxidation via the enhancement adiponectin signaling associated with the activation of both AMP-activated protein kinase and peroxisome proliferator-activated receptor α and ameliorates obesity-induced metabolic disorders, such as hyperinsulinemia and hyperlipidemia, although it does not suppress body weight gain and visceral fat accumulation in obese-diabetic model mice.

  5. Short term exercise induces PGC-1α, ameliorates inflammation and increases mitochondrial membrane proteins but fails to increase respiratory enzymes in aging diabetic hearts.

    Full Text Available PGC-1α, a transcriptional coactivator, controls inflammation and mitochondrial gene expression in insulin-sensitive tissues following exercise intervention. However, attributing such effects to PGC-1α is counfounded by exercise-induced fluctuations in blood glucose, insulin or bodyweight in diabetic patients. The goal of this study was to investigate the role of PGC-1α on inflammation and mitochondrial protein expressions in aging db/db mice hearts, independent of changes in glycemic parameters. In 8-month-old db/db mice hearts with diabetes lasting over 22 weeks, short-term, moderate-intensity exercise upregulated PGC-1α without altering body weight or glycemic parameters. Nonetheless, such a regimen lowered both cardiac (macrophage infiltration, iNOS and TNFα and systemic (circulating chemokines and cytokines inflammation. Curiously, such an anti-inflammatory effect was also linked to attenuated expression of downstream transcription factors of PGC-1α such as NRF-1 and several respiratory genes. Such mismatch between PGC-1α and its downstream targets was associated with elevated mitochondrial membrane proteins like Tom70 but a concurrent reduction in oxidative phosphorylation protein expressions in exercised db/db hearts. As mitochondrial oxidative stress was predominant in these hearts, in support of our in vivo data, increasing concentrations of H2O2 dose-dependently increased PGC-1α expression while inhibiting expression of inflammatory genes and downstream transcription factors in H9c2 cardiomyocytes in vitro. We conclude that short-term exercise-induced oxidative stress may be key in attenuating cardiac inflammatory genes and impairing PGC-1α mediated gene transcription of downstream transcription factors in type 2 diabetic hearts at an advanced age.

    Alleviation of hyperglycaemia and hyperlipidemia improves pancreatic β-cell function in type 2 diabetes. However, the underlying molecular mechanisms are still not well clarified. In this study, we aimed to elucidate how the expression alterations of key β-cell factors are altered by the short-term selective alleviation of glucotoxicity or lipotoxicity. We treated db/db mice for one week with empagliflozin and/or bezafibrate to alleviate glucotoxicity and/or liptotoxicity, respectively. The gene expression levels of Pdx1 and Mafa, and their potential targets, insulin 1, Slc2a2, and Glp1r, were higher in the islets of empagliflozin-treated mice, and levels of insulin 2 were higher in mice treated with both reagents, than in untreated mice. Moreover, compared to the pretreatment levels, Mafa and insulin 1 expression increased in empagliflozin-treated mice, and Slc2a2 increased in combination-treated mice. In addition, empagliflozin treatment enhanced β-cell proliferation assessed by Ki-67 immunostaining. Our date clearly demonstrated that the one-week selective alleviation of glucotoxicity led to the better expression levels of the key β-cell factors critical for β-cell function over pretreatment levels, and that the alleviation of lipotoxicity along with glucotoxicity augmented the favorable effects under diabetic conditions.

    The loss of neurotrophic factor support has been shown to contribute to the development of the central nervous system. Glial cell line‑derived neurotrophic factor (GDNF), a potent neurotrophic factor, is closely associated with apoptosis and exerts neuroprotective effects on numerous populations of cells. However, the underlying mechanisms of these protective effects remain unknown. In the present study, a significant increase in Bax levels and DNA fragmentation was observed in the hippocampus obtained from the brains of diabetic rats 60 days after diabetes had been induced. The apoptotic changes were correlated with the loss of GDNF/Akt signaling. GDNF administration was found to reverse the diabetes‑induced Bax and DNA fragmentation changes. This was associated with an improvement in the level of p‑Akt/Akt. In addition, combination of GDNF with a specific inhibitor of the phosphoinositide 3‑kinase (PI3K)/Akt pathway, Wortmannin, significantly abrogated the effects of GDNF on the levels of p‑Akt/Akt, Bax and DNA fragmentation. However, a p38 mitogen‑activated proten kinase (MAPK) inhibitor, SB203580, had no effect on the expression of p‑Akt/Akt, Bax or DNA fragmentation. These results demonstrate the pivotal role of GDNF as well as the PI3K/Akt pathway, but not the MAPK pathway, in the prevention of diabetes‑induced neuronal apoptosis in the hippocampus.

  15. Connexin-Based Therapeutics and Tissue Engineering Approaches to the Amelioration of Chronic Pancreatitis and Type I Diabetes: Construction and Characterization of a Novel Prevascularized Bioartificial Pancreas

    Directory of Open Access Journals (Sweden)

    J. Matthew Rhett

    2016-01-01

    Full Text Available Total pancreatectomy and islet autotransplantation is a cutting-edge technique to treat chronic pancreatitis and postoperative diabetes. A major obstacle has been low islet cell survival due largely to the innate inflammatory response. Connexin43 (Cx43 channels play a key role in early inflammation and have proven to be viable therapeutic targets. Even if cell death due to early inflammation is avoided, insufficient vascularization is a primary obstacle to maintaining the viability of implanted cells. We have invented technologies targeting the inflammatory response and poor vascularization: a Cx43 mimetic peptide that inhibits inflammation and a novel prevascularized tissue engineered construct. We combined these technologies with isolated islets to create a prevascularized bioartificial pancreas that is resistant to the innate inflammatory response. Immunoconfocal microscopy showed that constructs containing islets express insulin and possess a vascular network similar to constructs without islets. Glucose stimulated islet-containing constructs displayed reduced insulin secretion compared to islets alone. However, labeling for insulin post-glucose stimulation revealed that the constructs expressed abundant levels of insulin. This discrepancy was found to be due to the expression of insulin degrading enzyme. These results suggest that the prevascularized bioartificial pancreas is potentially a tool for improving long-term islet cell survival in vivo.

Methods Clinical data of 32 children with DKA as the first symptom of diabetes mellitus were investigated retrospectively. Results Twenty-nine patients had clinical fea tures including polydipsia, polyuria and weight loss. There were 16 patients complicated with respiratory tract infec tion, 1 patient with mumps, 1 patient with urinary tract infection, 2 patients with gastrointestinal infection. Eleven pa tients had gastrointestinal symptoms of nausea, vomiting and abdominal pain. Poor spirit, deep respiration, dehydra tion existed in all the patients. All the patients were improved and discharged after treatment with fluid replacement, re dress acidosis and electrolyte disturbance, insulin supplement. Conclusion Clinical manifestations of diabetes melli tus with ketoacidosis as the first symptom are not specific. The inducement is always infection of which the symptoms are outstanding. It's easy to be ignored or make misdiagnosis. We should increase vigilance on DKA when the children have poor spirit or consciousness disorders, dehydration, deep respiration, vomiting and abdominal pain, unexplained fatigue or weight loss. Blood glucose, arterial blood gas analysis and urine examination should be checked and once the diagnosis is confirmed, the combined therapeutic measures are fluid replacement, insulin treatment,supplement of potassium actively and redress acidosis carefully.%目的 总结以酮症酸中毒(DKA)为首发症状的糖尿病患儿的临床特点及诊治经过.方法 回顾性分析32例以DKA为首发症状的糖尿病患儿的临床资料.结果 29例有多饮、多尿、消瘦表现;伴有呼吸道感染者16例,腮腺炎1例,尿路感染1例,消化道感染2例,有恶心、呕吐、腹痛等消化道症状者11例.32例均有精神差、呼吸深大及脱水表现.

    2014-02-01

    Diabetic neuropathy is a heterogeneous group of disorders with extremely complex pathophysiology and affects both somatic and autonomic components of the nervous system. Neuropathy is the most common chronic complication of diabetes mellitus. Metabolic disruptions in the peripheral nervous system, including altered protein kinase C activity, and increased polyol pathway activity in neurons and Schwann cells resulting from hyperglycemia plays a key role in the development of diabetic neuropathy. These pathways are related to the metabolic and/or redox state of the cell and are the major source of damage. Activation of these metabolic pathways leads to oxidative stress, which is a mediator of hyperglycemia induced cell injury and a unifying theme for all mechanisms of diabetic neuropathy. The therapeutic intervention of these metabolic pathways is capable of ameliorating diabetic neuropathy but therapeutics which target one particular mechanism may have a limited success. Available therapeutic approaches are based upon the agents that modulate pathogenetic mechanisms (glycemic control) and relieve the symptoms of diabetic neuropathy. This review emphasizes the pathogenesis, presently available therapeutic approaches and future directions for the management of diabetic neuropathy.

    To determine the prevalence and predictors of reversible myocardial perfusion defects, indicative of myocardial ischaemia, in patients with mild, stable anginal complaints [Canadian Cardiovascular Society classification (CCS) I-II/IV] and diabetes mellitus type 2 (T2DM). A total of 329 patients with T2DM and stable, mild anginal symptoms (CCS I-II/IV) underwent myocardial perfusion scintigraphy. Perfusion images were assessed using a five-point (semi)-quantitative scoring system according to a 17-segment myocardial model. One-hundred and fifty-six (47%) patients showed reversible myocardial perfusion defects defined as a summed difference score of {>=}3. Male gender [odds ratio (OR) 2.28, 95% CI 1.4-3.71, p=0.001], previous myocardial infarction (MI) without revascularisation (OR 3.04, 95% CI 1.28-7.24, p=0.01), and the use of two or more classes of anti-anginal medication (OR 2.36, 95% CI 1.48-3.76, p<0.001) were independent predictors for the presence of reversible defects. By contrast, lipid-lowering therapy reduced the possibility of reversible perfusion defects (OR 0.56, 95% CI 0.33-0.95, p=0.03). Approximately half of the patients with mild, stable angina pectoris and T2DM showed evidence of myocardial ischaemia. Male gender, previous MI and the use of anti-anginal medication were positive predictors and lipid-lowering therapy was a negative predictor for the results of the scintigraphic stress test. (orig.)

    2014-01-01

    Diabetes insipidus is an uncommon disorder of water-electrolyte balance characterized by the excretion of abnormally large volumes of diluted urine (polyuria) and increased fluid intake (polydipsia). The disease may result from the insufficient production of vasopressin, its increased degradation, an impaired response of kidneys to vasopressin, or may be secondary to excessive water intake. Patients with severe and uncompensated symptoms may develop marked dehydration, neurologic symptoms and encephalopathy, and therefore diabetes insipidus can be a life-threatening condition if not properly diagnosed and managed. Patients with diabetes insipidus require treatment with desmopressin or drugs increasing sensitivity of the distal nephron to vasopressin, but this treatment may be confusing because of the disorder's variable pathophysiology and side-effects of pharmacotherapy. This review summarizes the current knowledge on different aspects of the pathophysiology, classification, clinical presentation, diagnosis, and management of diabetes insipidus. The reader is also provided with some practical recommendations on dealing with patients suffering from this disease.

    Diabetic nephropathy is a lethal complication of diabetes mellitus and a major type of chronic kidney disease. Dysregulation of the Akt pathway and its downstream cascades, including mTOR, NFκB, and Erk1/2, play a critical role in the development of diabetic nephropathy. Astragaloside IV is a major component of Huangqi and exerts renal protection in a mouse model of type 1 diabetes. The current study was undertaken to investigate the protective effects of diet supplementation of AS-IV on renal injury in db/db mice, a type 2 diabetic mouse model. Results showed that administration of AS-IV reduced albuminuria, ameliorated changes in the glomerular and tubular pathology, and decreased urinary NAG, NGAL, and TGF-β1 in db/db mice. AS-IV also attenuated the diabetes-related activation of Akt/mTOR, NFκB, and Erk1/2 signaling pathways without causing any detectable hepatotoxicity. Collectively, these findings showed AS-IV to be beneficial to type 2 diabetic nephropathy, which might be associated with the inhibition of Akt/mTOR, NFκB and Erk1/2 signaling pathways.

    Diabetes mellitus is the commonest cause of an autonomic neuropathy in the developed world. Diabetic autonomic neuropathy causes a constellation of symptoms and signs affecting cardiovascular, urogenital, gastrointestinal, pupillomotor, thermoregulatory, and sudomotor systems. Several discrete syndromes associated with diabetes cause autonomic dysfunction. The most prevalent of these are: generalized diabetic autonomic neuropathy, autonomic neuropathy associated with the prediabetic state, treatment-induced painful and autonomic neuropathy, and transient hypoglycemia-associated autonomic neuropathy. These autonomic manifestations of diabetes are responsible for the most troublesome and disabling features of diabetic peripheral neuropathy and result in a significant proportion of the mortality and morbidity associated with the disease.

    [Objective ] The present study was to investigate effects of total saponins from cornus officinalis sieb. on the testis in STZ-induced experimental diabetic rats. [Methods] Male Sprague Dawley rat was i.p administered by streptozotocin (STZ) at a single dose of 60 mg/kg to induce diabetic mellitus. On the 28th day the animals with serum glucose level more than 16.7 mmol/L were selected and divided into three groups: diabetic group, CTS treated group (80 mg/kg, p.o), methyltestosterone treated group (3 mg/kg, p.o), 12 rats each group. A non-diabetic group was set as a control. 0.5% CMC-Na suspension was administered for consecutive 28 days and only medium was taken in control and diabetic group. The testis, epididymis, seminal vesicle of rats were weighed and the ratio of organ weight/ body weight was calculated. Glucose, testosterone in the serum and special enzymes such as lactate dehydrogenase (LDH), acid phosphatase (ACP), and -γ-glutamyltranspeptidase (-γ-GT) activity in the testis tissue were determined, as well as the testis block was stained by haematoxylin- eosin and observed under light microscope. [Results] Rats in diabetic group shown increased glucose level and declined testosterone in the serum, decreased LDH, ACP, -γ-GT activity in the testis, compared with the control. Atrophied seminiferous tubules, decreased spermatogenic cells were shown in the testis of rats in diabetic group. These alterations were improved in total saponins treated group.

    2015-05-01

    Full Text Available The majority of diabetic patients with renal involvement are not biopsied. Studies evaluating histological findings in renal biopsies performed in diabetic patients have shown that approximately one third of the cases will show pure diabetic nephropathy, one third a non-diabetic condition and another third will show diabetic nephropathy with a superimposed disease. Early diagnosis of treatable non-diabetic diseases in diabetic patients is important to ameliorate renal prognosis. The publication of the International Consensus Document for the classification of type 1 and type 2 diabetes has provided common criteria for the classification of diabetic nephropathy and its utility to stratify risk for renal failure has already been demonstrated in different retrospective studies. The availability of new drugs with the potential to modify the natural history of diabetic nephropathy has raised the question whether renal biopsies may allow a better design of clinical trials aimed to delay the progression of chronic kidney disease in diabetic patients.

    The purpose of this study was to evaluate the prevalence of cardiac autonomic neuropathy (CAN) in a cohort of patients with type 2 diabetes, truly asymptomatic for coronary artery disease (CAD), using heart rate variability (HRV) and {sup 123}I-metaiodobenzylguanidine ({sup 123}I-mIBG) myocardial scintigraphy. The study group comprised 88 patients with type 2 diabetes prospectively recruited from an outpatient diabetes clinic. In all patients myocardial perfusion scintigraphy, CAN by HRV and {sup 123}I-mIBG myocardial scintigraphy were performed. Two or more abnormal tests were defined as CAN-positive (ECG-based CAN) and one or fewer as CAN-negative. CAN assessed by {sup 123}I-mIBG scintigraphy was defined as abnormal if the heart-to-mediastinum ratio was <1.8, the washout rate was >25%, or the total defect score was >13. The prevalence of CAN in patients asymptomatic for CAD with type 2 diabetes and normal myocardial perfusion assessed by HRV and {sup 123}I-mIBG scintigraphy was respectively, 27% and 58%. Furthermore, in almost half of patients with normal HRV, {sup 123}I-mIBG scintigraphy showed CAN. The current study revealed a high prevalence of CAN in patients with type 2 diabetes. Secondly, disagreement between HRV and {sup 123}I-mIBG scintigraphy for the assessment of CAN was observed. (orig.)

  18. Assessment of cerebral perfusion and cerebrovascular reserve in insulin-dependent diabetic patients without central neurological symptoms by means of 99mTc-HMPAO SPET with acetazolamide

    International Nuclear Information System (INIS)

    The detection of subclinical abnormalities in cerebral blood flow could be of great value in identifying diabetic patients at risk of stroke. The aim of this study was to assess the contribution of semiquantified post-acetazolamide technetium-99m hexamethylpropylene amine oxime single-photon emission tomography (99mTc-HMPAO SPET) in 15 diabetic patients with no clinical history of central neurological disease. After baseline 99mTc-HMPAO SPET, a second SPET scan was acquired after activation of the cerebrovascular reserve (CVR) with an injection of 1 g of acetazolamide (post-ACZ SPET). Semiquantitative analysis was made in 16 regions of interest (ROIs) drawn for each of the three supratentorial slices selected, and in two ROIs in the infratentorial slice. The CVR was calculated in each ROI by subtracting the decay-corrected baseline images from those obtained in the post-ACZ SPET and expressed as the percent increase in the average counts between the two scans. Baseline perfusion and CVR values in the study group were compared with the corresponding values in a control group. Of 750 cortical ROIs studied, 332 showed a decreased CVR (44.3%). The baseline perfusion SPET study showed hypoperfusion in 65 ROIs (8.6%) and hyperperfusion in 56 (7.4%). Of the 65 hypoperfused regions, 66.2% had a normal CVR and 33.8% had a decreased CVR, whereas of the 56 hyperperfused regions, 51.8% had a CVR within normal limits and 48.2% showed a decreased CVR. In conclusion, in comparison with baseline 99mTc-HMPAO SPET, the ACZ activation test provided additional information in the study of cerebrovascular impairment, and allowed characterisation of the subclinical abnormalities in the population studied. The technique may therefore prove useful in evaluating future preventive strategies for stroke in diabetic patients. (orig.)

    Full Text Available Background: Diabetes mellitus is a serious disease affecting about 5% of people worldwide. Although several studies have indicated hypoglycemic activities of Gynura divaricata (GD, the mechanisms by which GD improves the symptoms of diabetes remain unclear. Objective: The aim of this study was to investigate the potential hypoglycemic effects of GD. Design: The leaves and stems of GD were prepared and lyophilized into a powder, which was added to the diet of mice with type 2 diabetes induced by a high-fat diet in combination with streptozotocin for 4 weeks. During this period, fasting blood glucose (FBG levels and body weight of mice were measured. In addition, at the end of the experiment, a series of assays was performed. Results: GD administration effectively alleviates insulin resistance and induces a decrease in FBG by 59.54% in 1.2% (L GD-treated diabetic group and 56.13% in 4.8% (H GD-treated diabetic group after 4 weeks, respectively, relative to diabetic model mice. The antioxidant capacity was improved by increasing the activities of glutathione peroxidase (GSH-Px and total superoxide dismutase (T-SOD by 64.87% and 53.42% in treatment group H, compared to diabetic model mice, while GD treatment induced a significant decrease in malondialdehyde (MDA level by 50% in treatment group L, compared to the level in diabetic model mice. Furthermore, glucose metabolism was ameliorated by the increased glycogen synthesis in the livers of diabetic mice. In addition, we also demonstrated that the messenger RNA (mRNA and protein expression levels of AKT, PI3K and PDK-1, which are involved in insulin signaling, were significantly increased. Conclusions: Oral administration of the GD-lyophilized powder has been effectively hypoglycemic, which is done by activating insulin signaling and improving antioxidant capacity in mice with type 2 diabetes.

    We evaluated the effect of chicory (Cichorium intybus L.) seed extract (CI) on hepatic steatosis caused by early and late stage diabetes in rats (in vivo), and induced in HepG2 cells (in vitro) by BSA-oleic acid complex (OA). Different dosages of CI (1.25, 2.5 and 5 mg/ml) were applied along with OA (1 mM) to HepG2 cells, simultaneously and non-simultaneously; and without OA to ordinary non-steatotic cells. Cellular lipid accumulation and glycerol release, and hepatic triglyceride (TG) content were measured. The expression levels of sterol regulatory element-binding protein-1c (SREBP-1c) and peroxisome proliferator-activated receptor alpha (PPARα) were determined. Liver samples were stained with hematoxylin and eosin (H&E). Significant histological damage (steatosis-inflammation-fibrosis) to the cells and tissues and down-regulation of SREBP-1c and PPARα genes that followed steatosis induction were prevented by CI in simultaneous treatment. In non-simultaneous treatment, CI up-regulated the expression of both genes and restored the normal levels of the corresponding proteins; with a greater stimulating effect on PPARα, CI acted as a PPARα agonist. CI released glycerol from HepG2 cells, and targeted the first and the second hit phases of hepatic steatosis. A preliminary attempt to characterize CI showed caffeic acid, chlorogenic acid, and chicoric acid, among the constituents. PMID:23603006

    Introduction Diabetes may affect the human body’s systems and organs, including the eye. Diabetic retinopathy is the 5th leading cause of blindness globally. Diabetic subjects demonstrated dry eye symptoms that were also supported by the low values of the clinical tests. Purpose This study aimed to compare the dry eye symptoms and signs between diabetics and non-diabetics and tear functions between diabetic subjects with and without dry eye. Methods This retrospective study was based on the observation of 643 medical files. Using a convenience sampling method, 88 subjects were found to report diabetes mellitus. The information extracted from the files included: date of first examination, age at first visit, gender, past ocular history, systemic disease, symptoms of dry eye disease and details of clinical diagnostic signs. Non-contact lens wearers were excluded. A group of 88, age and gender matched, control subjects were included for this comparison study. Results The percentage of dry eye symptoms was higher in diabetic subjects (15.9%) compared with non-diabetic subjects (13.6%; peye symptoms was also higher in diabetics with dry eye (63%) than in diabetics without dry eye (36.9%; peye (p=0.046). The corneal staining was significantly different between diabetic subjects with and without dry eye (p=0.028). Conclusion Dry eye symptoms were significantly associated with diabetics. Tear break up time was significantly shorter in diabetics with dry eye compared to diabetics without dry eye.

    OBJECTIVE To study the effect of hypoxia on the blood glucose and symptom in experimental diabetic rats. METHODS The model was established by long-term diet high sugar and fat food, lower dose (30mg/kg body weight) of the streptozocin (STZ) treated rats. They were randomly divided into model control group and hypoxia interfering group. Model control group lived under normal environment while hypoxia interfering group exposed to hypoxia for an hour per day in hypoxic tent (oxygen concentration 15.4% ?0.2%), six days a week for four weeks. RESULTS (1) The rats had the typical symptoms of diabetic. (2) Compared with the rats in Model control group, the ones in hypoxia interfering group had a non-significantly higher fasting blood glucose (FPG) (P > 0.05) and a decreased food intake (P < 0.05) as well as decreased weight (P < 0.05) after four-week intervention period. But there was no significant difference in the drinking, the fat Index, the insulin sensibility index (ISI) and the insulin resistance index (HOMA-IR) between the two groups. CONCLUSION Four-week hypoxia interfering had no improvement to the diabetic symptoms in experimental diabetic rats apparently, in contrast it can result in a quick decrease in weight and an ascendant trend in FPG.%目的 探索低氧干预对实验性糖尿病大鼠血糖及其病症的影响.方法 采用长期高糖高脂膳食加小剂量链脲佐菌素(STZ)的方法建立糖尿病大鼠模型,将复制成功的模型大鼠随机分为模型对照组与低氧干预组.模型对照组在常氧环境下正常生活,低氧干预组大鼠每天在低氧帐篷内低氧暴露1h(O2浓度15.4%±0.2%)、每周休息1d、共干预4周.结果 (1)糖尿病大鼠出现了典型的“三多一少”特征.(2)通过4周实验干预,低氧干预组大鼠血糖稍高于模型对照组(P>0.05)、摄食量明显低于模型对照组(P<0.05)、体重下降显著大于模型对照组(P<0.05)、肥胖指数、饮水量、胰岛素敏感指

    Full Text Available Introduction: Diabetic nephropathy is one of the most frequent and serious complications of diabetes mellitus. This study was designed to evaluate the effect of green tea (GT extract and low doses of 0.5 Gy -radiation (R on diabetic nephropathy (DN of rats. Materials and methods: Male Swiss albino rats were used in this study. DN was induced in rats using streptozotocin (45 mg/kg body weight. The rats were divided into five groups DN, DN+R, DN+GT, DN+GT+R and a sham treatment control group. Throughout the experimental period (3and 6 weeks animals body weight, glucose and insulin levels were evaluated. Kidney functions assay (serum urea and creatinin were recorded. Histopathological observations in kidney tissue, DNA and glycogen intensity were also detected. Results: Diabetic rats exhibited many symptoms including loss of body weight, increase in blood glucose level and decrease in serum insulin levels. Increase in serum urea and creatinin levels. Diabetic kidney showed a moderate renal damage, multifocal clarifications and vacuolations. Carbohydrates intensity showed a significant increase and DNA intensity showed many alterations. Improvements in glomerular and tubulointerstitial lesions were demonstrated in the diabetic rat group exposed to low doses of -radiation or supplemented by green tea either alone or combined in addition to amelioration in glucose, insulin urea and creatinin levels. Conclusion: The present study demonstrates the efficacy of low doses of - radiation and in reducing diabetes-induced functional and histological alterations in the kidneys. The longterm control of blood glucose levels using low doses of -radiation or green tea either alone or combined could prevent the progression of diabetes mellitus, and therefore, nephropathy could be prevented.

    Sensory abnormality is one of the serious complications in diabetes. Since the effective therapeutic regimen to ameliorate the diabetic sensory abnormality is very few, the present study was then designed to investigate the effect of zinc L-carnosine on the changes of nociceptive threshold in diabetic mice. Zinc L-carnosine (75-300 mg/kg, p.o.) was administered once daily from 1 day after streptozotocin treatment. Diabetic mice showed shorter tail-flick latency at 1-4 weeks after streptozotocin treatment and longer tail-flick latency at 6-9 weeks after its treatment. The shortened tail-flick latency in early stage of diabetic mice was ameliorated by treatment with zinc L-carnosine. Moreover, zinc L-carnosine also slowed the onset of hypoalgesia in diabetic mice. Tail-flick latency in non-diabetic mice was not affected by the zinc L-carnosine treatment, indicating that zinc L-carnosine did not affect normal nociceptive transmission. Moreover, L-carnosine, but not zinc sulfate, ameliorated the abnormal sensory perception in diabetic mice. Interestingly, the ameliorative effect of zinc l-carnosine on the abnormal sensory perception in diabetic mice is much stronger than that of L-carnosine. These results provide the evidence of the ameliorative potential of zinc L-carnosine on the progressive diabetic neuropathy. Moreover, L-carnosine combined with zinc shows more potent amelioration of abnormal sensory perception in diabetic mice than by itself. PMID:18930724

    Genetic loss of collagen VII causes recessive dystrophic epidermolysis bullosa (RDEB)-a severe skin fragility disorder associated with lifelong blistering and disabling progressive soft tissue fibrosis. Causative therapies for this complex disorder face major hurdles, and clinical implementation remains elusive. Here, we report an alternative evidence-based approach to ameliorate fibrosis and relieve symptoms in RDEB. Based on the findings that TGF-β activity is elevated in injured RDEB skin, we targeted TGF-β activity with losartan in a preclinical setting. Long-term treatment of RDEB mice efficiently reduced TGF-β signaling in chronically injured forepaws and halted fibrosis and subsequent fusion of the digits. In addition, proteomics analysis of losartan- vs. vehicle-treated RDEB skin uncovered changes in multiple proteins related to tissue inflammation. In line with this, losartan reduced inflammation and diminished TNF-α and IL-6 expression in injured forepaws. Collectively, the data argue that RDEB fibrosis is a consequence of a cascade encompassing tissue damage, TGF-β-mediated inflammation, and matrix remodeling. Inhibition of TGF-β activity limits these unwanted outcomes and thereby substantially ameliorates long-term symptoms.

    Full Text Available O diabetes mellitus possui elevada prevalência, acometendo cerca de 7% da população brasileira. Em torno de 20% a 30% dos pacientes com diabetes apresentam depressão. A depressão pode atuar como um fator de risco para o desenvolvimento do diabetes, piorar seus sintomas e interferir com o autocuidado dos pacientes. Quando não tratada adequadamente, a depressão nesses pacientes tende a evoluir com elevada taxa de recorrência. Entre os tratamentos disponíveis, encontramos na literatura um benefício da psicoterapia, cognitiva ou cognitivo-comportamental, para melhora dos sintomas depressivos, mas sem evidência de um benefício no controle glicêmico. Os antidepressivos tricíclicos, em especial os com maior ação noradrenérgica, e os inibidores da monoaminoxidase (IMAOs tendem a aumentar os níveis glicêmicos. A bupropiona não interfere na glicemia e há evidências de que os inibidores seletivos de recaptura de serotonina (ISRS melhoram os níveis glicêmicos e podem reduzir a taxa de recaídas, mostrando-se boas opções de tratamento farmacológico. A eletroconvulsoterapia também é uma estratégia interessante para esses pacientes, recomendando-se, no entanto, monitorização da glicemia. Não foram encontrados estudos significativos sobre os demais antidepressivos disponíveis para comercialização.Diabetes mellitus has an estimated prevalence of 7% among Brazilian population. Around 20% to 30% of these patients have a depressive disorder. Depression can work as risk factor to the development of diabetes, can worse its symptoms and interfere with self-care. When not adequately treated, depressive disorder in these patients tends to have high rates of recurrence. Among the available treatments literature shows a benefit of psychotherapy, mainly cognitive or cognitive-behavioral, in ameliorating depressive symptoms, but without impact on glycaemic control.

    Adipose tissue dysfunction correlates with the development of diabetes. Mice with an adipocyte-specific deletion of the SUMO-specific protease SENP1 develop symptoms of type-1 diabetes mellitus (T1DM). Peri-pancreatic adipocytes (PATs) exert both systemic and paracrine effects on pancreases function. Our recent studies report that PATs of SENP1-deficient mice have increased proinflammatory cytokine production compared with other adipose depots. Proinflammatory cytokines produced from PATs not only have direct cytotoxic effects on pancreatic islets, but also increase CCL5 expression in adjacent pancreatic islets, which induces persistent inflammation in pancreases by acquisition of Th1 and Th17 effector T cell subsets. Small ubiquitin-like modifier (SUMO) can post-translationally conjugate to cellular proteins (SUMOylation) and modulate their biological functions. Several components in SUMOylation associate with T1DM susceptibility. We find that SUMOylation of NF-κB essential molecule NEMO augments NF-κB activity, NF-κB-dependent cytokine production and pancreatic inflammation. NF-κB inhibitor should provide therapeutic approach to block PAT inflammation and ameliorate the T1DM phenotype. We further propose that adipocytes in PATs may play a primary role in establishing pancreatic immune regulation at onset of diabetes, providing new insights into the molecular pathogenesis of type 1 diabetes.

    Ghrelin, an acylated peptide produced in the stomach, increases food intake and growth hormone secretion, suppresses inflammation and oxidative stress, and promotes cell survival and proliferation. We investigated the pharmacological potential of ghrelin in the treatment of polyneuropathy in uncontrolled streptozotocin (STZ)-induced diabetes in mice. Ghrelin or desacyl-ghrelin was administered daily for 4 weeks after STZ-induced diabetic polyneuropathy had developed. Ghrelin administration did not alter food intake, body weight gain, blood glucose levels, or plasma insulin levels when compared with mice given saline or desacyl-ghrelin administration. Ghrelin administration ameliorated reductions in motor and sensory nerve conduction velocities in diabetic mice and normalized their temperature sensation and plasma concentrations of 8-isoprostaglandin {alpha}, an oxidative stress marker. Desacyl-ghrelin failed to have any effect. Ghrelin administration in a mouse model of diabetes ameliorated polyneuropathy. Thus, ghrelin's effects represent a novel therapeutic paradigm for the treatment of this otherwise intractable disorder.

    Peripheral painful neuropathy is one of the most common complications in diabetes and necessitates improved treatment. Secoisolariciresinol diglycoside (SDG), a predominant lignan in flaxseed, has been shown in our previous studies to exert antidepressant-like effect. As antidepressant drugs are clinically used to treat chronic neuropathic pain, this work aimed to investigate the potential analgesic efficacy of SDG against diabetic neuropathic pain in a mouse model of type 1 diabetes. We subjected mice to diabetes by a single intraperitoneal (i.p.) injection of streptozotocin (STZ, 200 mg/kg), and Hargreaves test or von Frey test was used to assess thermal hyperalgesia or mechanical allodynia, respectively. Chronic instead of acute SDG treatment (3, 10 or 30 mg/kg, p.o., twice per day for three weeks) ameliorated thermal hyperalgesia and mechanical allodynia in diabetic mice, and these analgesic actions persisted about three days when SDG treatment was terminated. Although chronic treatment of SDG to diabetic mice did not impact on the symptom of hyperglycemia, it greatly attenuated excessive oxidative stress in sciatic nerve and spinal cord tissues, and partially counteracted the condition of weight decrease. Furthermore, the analgesic actions of SDG were abolished by co-treatment with the reactive oxygen species donor tert-butyl hydroperoxide (t-BOOH), but potentiated by the reactive oxygen species scavenger phenyl-N-tert-butylnitrone (PBN). These findings indicate that chronic SDG treatment can correct neuropathic hyperalgesia and allodynia in mice with type 1 diabetes. Mechanistically, the analgesic actions of SDG in diabetic mice may be associated with its antioxidant activity. PMID:26494631

    Peripheral painful neuropathy is one of the most common complications in diabetes and necessitates improved treatment. Fisetin, a naturally occurring flavonoid, has been reported to exert antidepressant-like effect in previous studies. As antidepressant drugs are employed clinically to treat neuropathic pain, this work aimed to investigate whether fisetin possess beneficial effect on diabetic neuropathic pain and explore the mechanism(s). We subjected mice to diabetes by a single intraperitoneal (i.p.) injection of streptozotocin (200mg/kg), and von Frey test or Hargreaves test was used to assess mechanical allodynia or thermal hyperalgesia, respectively. Chronic treatment of diabetic mice with fisetin not only ameliorated the established symptoms of thermal hyperalgesia and mechanical allodynia, but also arrested the development of neuropathic pain when given at low doses. Although chronic fisetin administration did not impact on the symptom of hyperglycemia in diabetic mice, it reduced exacerbated oxidative stress in tissues of spinal cord, dorsal root ganglion (DRG) and sciatic verve. Furthermore, the analgesic actions of fisetin were abolished by repetitive co-treatment with the reactive oxygen species (ROS) donor tert-butyl hydroperoxide (t-BOOH), but potentiated by the ROS scavenger phenyl-N-tert-butylnitrone (PBN). Finally, acute blockade of spinal GABAA receptors by bicuculline totally counteracted such fisetin analgesia. These findings indicate that chronic fisetin treatment can delay or correct neuropathic hyperalgesia and allodynia in mice with type 1 diabetes. Mechanistically, the present fisetin analgesia may be associated with its antioxidant activity, and spinal GABAA receptors are likely rendered as downstream targets. PMID:26520392

    Diabetes is a global health problem, with a challenging epidemiology. It is one of the major health problems affecting countries around the world, particularly the UK (World Health Organization [WHO], 2006; Department of Health [DH], 2006b). It is also a growing public health threat in the US (Mokdad et al, 2001). As a result, diabetes has become an important public health issue, prompting the WHO and International Diabetes Federation (IDF) to adopt the theme 'Diabetes for Everyone' for World Diabetes Day 2006. In 2007, on World Diabetes Day, the United Nations also launched its 'Living with Diabetes at School' campaign, in response to the growing diabetes 'epidemics' (Diabetes UK, 2007). This article provides an overview of diabetes mellitus and its acute- and long-term management, including definition, aetiology, pathophysiology, classification, signs, symptoms and complications. The role of the nurse in providing patient-centred care for people with diabetes is emphasized.

    In keeping with the already known high prevalence of diabetes among residents of the Jewish Home for the Aged, Toronto, annual screening disclosed an average incidence of 25.5% of abnormal glucose tolerance (two-hour post-glucose blood sugars above 140 mg./100 ml.) in residents not known to be diabetic. Forty-five (47%) of the 94 residents with abnormal screening values were considered subsequently to be diabetic according to our criteria. Long-term follow-up, particularly of 81 residents initially normoglycemic in 1964-5, confirmed that the natural course of glucose tolerance in this population was one of progressive deterioration. By contrast, improvement amounting to remission has been demonstrated in nine out of 20 residents several years after they had been declared diabetic, and is thought to have been induced by dietotherapy. Moderate hyperglycemia per se did not cause symptoms in these almost always keto-resistant and usually aglycosuric aged diabetics, who often claimed they felt better when hyperglycemic. Hypoglycemia was an ever present danger when anti-diabetic medication was used; it was the main reason for undertreatment. So far, data from our long-term study have not shown morbidity to be markedly increased in the diabetics, and mortality was found to be evenly distributed among diabetic and non-diabetic male residents. However, in the females there was a clear correlation between mortality rate and the diminished glucose tolerance. What may appear as overdiagnosis of diabetes in the aged is recommended in the hope that early institution of dietary treatment will delay the development of clinical diabetes and the need for anti-diabetic agents. This, in turn, would prevent iatrogenic hypoglycemia. It would also reduce the severity and frequency of spontaneous hypoglycemia which, we believe, occurs more commonly in the early phase of diabetes in the aged than is generally realized.

    Full Text Available Diabetes Insipidus (DI is a heterogeneous clinical syndrome of disturbance in water balance, characterized by polyuria (urine output > 4 ml/kg/hr, polydypsia (water intake > 2 L/m 2 /d and failure to thrive. In children, Nephrogenic DI (NDI is more common than Central DI (CDI, and is often acquired. The signs and symptoms vary with etiology, age at presentation and mode of onset. Neonates and infants with NDI are severely affected and difficult to treat. Diagnosis is based on the presence of high plasma osmolality and low urinary osmolality with significant water diuresis. Water deprivation test with vasopressin challenge, though has limitations, is done to differentiate NDI and CDI and diagnose their partial forms. Measurement of urinary aquaporin 2 and serum copeptin levels are being studied and show promising diagnostic potential. Magnetic Resonance Imaging (MRI pituitary helps in the etiological diagnosis of CDI, absence of posterior pituitary bright signal being the pathognomic sign. If pituitary stalk thickening of < 2 mm is present, these children need to be monitored for evolving lesion. Neonates and young infants are better managed with fluids alone. Older children with CDI are treated with desmopressin. The oral form is safe, highly effective, with more flexibility of dosing and has largely replaced the intranasal form. In NDI besides treatment of the underlying cause, use of high calorie low solute diet and drugs to ameliorate water excretion (thiazide, amelioride, indomethacin are useful. Children with NDI however well treated, remain short and have mental retardation on follow up.

    BACKGROUND Glucagon-like peptide-1 (GLP-1), a potent and selective agonist for the GLP-1 receptor, ameliorates the symptoms of diabetes through stimulation of insulin secretion. Exenatide is a potent and selective agonist for the GLP-1 receptor. Cell adhesion molecules are members of the immunoglobulin superfamily and are involved in synaptic rearrangements in the mature brain. MATERIAL AND METHODS The present study demonstrated the effects of exenatide treatment (0.1 µg/kg, subcutaneously, twice daily for 2 weeks) on the gene expression levels of cell adhesion molecules, neural cell adhesion molecule (NCAM), intercellular cell adhesion molecule (ICAM), and vascular cell adhesion molecule (VCAM) in the brain tissue of diabetic BALB/c male mice by real-time quantitative polymerase chain reaction (PCR). Diabetes was induced by streptozotocin/nicotinamide (STZ-NA) injection to male mice. RESULTS The results of this study revealed that hippocampal gene expression of NCAM, ICAM, and VCAM were found to be up-regulated in STZ-NA-induced diabetic mice compared to those of controls. A significant decrease in the gene expression levels of NCAM, ICAM, and VCAM were determined after 2 weeks of exenatide administration. CONCLUSIONS Cell adhesion molecules may be involved in the molecular mechanism of diabetes. Exenatide has a strong beneficial action in managing diabetes induced by STZ/NA by altering gene expression of NCAM, ICAM, and VCAM. PMID:27465247

  12. The Adenosinergic System in Diabetic Retinopathy

    2016-01-01

    Full Text Available The neurodegenerative and inflammatory environment that is prevalent in the diabetic eye is a key player in the development and progression of diabetic retinopathy. The adenosinergic system is widely regarded as a significant modulator of neurotransmission and the inflammatory response, through the actions of the four types of adenosine receptors (A1R, A2AR, A2BR, and A3R, and thus could be revealed as a potential player in the events unfolding in the early stages of diabetic retinopathy. Herein, we review the studies that explore the impact of diabetic conditions on the retinal adenosinergic system, as well as the role of the said system in ameliorating or exacerbating those conditions. The experimental results described suggest that this system is heavily affected by diabetic conditions and that the modulation of its components could reveal potential therapeutic targets for the treatment of diabetic retinopathy, particularly in the early stages of the disease.

  15. Management of diabetic gastroparesis

    Directory of Open Access Journals (Sweden)

    Badr M Aljarallah

    2011-01-01

    Full Text Available Symptoms suggestive of gastroparesis occur in 5% to 12% of patients with diabetes. Such a complication can affect both prognosis and management of the diabetes; therefore, practicing clinicians are challenged by the complex management of such cases. Gastroparesis is a disorder characterized by a delay in gastric emptying after a meal in the absence of a mechanical gastric outlet obstruction. This article is an evidence-based overview of current management strategies for diabetic gastroparesis. The cardinal symptoms of diabetic gastroparesis are nausea and vomiting. Gastroesophageal scintiscanning at 15-minute intervals for 4 hours after food intake is considered the gold standard for measuring gastric emptying. Retention of more than 10% of the meal after 4 hours is considered an abnormal result, for which a multidisciplinary management approach is required. Treatment should be tailored according to the severity of gastroparesis, and 25% to 68% of symptoms are controlled by prokinetic agents. Commonly prescribed prokinetics include metoclopramide, domperidone, and erythromycin. In addition, gastric electrical stimulation has been shown to improve symptoms, reduce hospitalizations, reduce the need for nutritional support, and improve quality of life in several open-label studies.

    2005-01-01

    Full Text Available Diabetic retinopathy is one of the common complications of diabetes. Unfortunately, in many cases the patient is not aware of any symptoms until it is too late for effective treatment. Through analysis of evoked potential response of the retina, the optical nerve, and the optical brain center, a way will be paved for early diagnosis of diabetic retinopathy and prognosis during the treatment process. In this paper, we present an artificial-neural-network-based method to classify diabetic retinopathy subjects according to changes in visual evoked potential spectral components and an anatomically realistic computer model of the human eye under normal and retinopathy conditions in a virtual environment using 3D Max Studio and Windows Movie Maker.

  1. Diabetic bladder dysfunction

    Institute of Scientific and Technical Information of China (English)

    Guiming Liu; Firouz Daneshgari

    2014-01-01

    Objective To review studies on diabetic bladder dysfunction (DBD),a common and bothersome complication of diabetes mellitus.Data sources We performed a search of the English literature through PubMed.The key words used were "diabetes" and "bladder dysfunction" or "cystopathy".Our own data and perspective are included in the discussion.Study selection Studies containing data relevant to DBD were selected.Because of the limited length of this article,we also referenced reviews that contain comprehensive amalgamations of relevant literature.Results The classic symptoms of DBD are decreased bladder sensation,increased bladder capacity,and impaired bladder emptying with resultant elevated post-void residual urine.However,recent clinical and experimental evidence indicate a strong presence of storage problems such as urge incontinence in diabetes.Recent studies of DBD in animal models of type 1 diabetes have revealed temporal effects of diabetes,causing an early phase of compensatory bladder function and a later phase of decompensated bladder function.The pathophysiology of DBD is multifactorial,including disturbances of the detrusor,urothelium,autonomic nerves,and urethra.Polyuria and hyperglycemia play important but distinctive roles in induction of bladder dysfunction in type 1 diabetes.Polyuria causes significant bladder hypertrophy in the early stage of diabetes,whereas oxidative stress in the bladder caused by chronic hyperglycemia may play an important role in the late stage failure of bladder function.Conclusions DBD includes time-dependent and mixed manifestations.The pathological alterations include muscle,nerve,and urothelium.Polyuria and hyperglycemia independently contribute to the pathogenesis of DBD.Treatments for DBD are limited.Future clinical studies on DBD in type 1 and type 2 diabetes should be investigated separately.Animal studies of DBD in type 2 diabetes are needed,from the natural history to mechanisms.Further understanding of the molecular

    2015-09-01

    The global statistics of diabetes mellitus in year 2013 indicated, about 382 million people had this disease worldwide, with type 2 diabetes making up about 90 % of the cases. This is equal to 8.3 % of the adult population with equal rates in both women and men. In year 2012 and 2013 diabetes resulted in mortality of 1.5-5.1 million people per year, making it the 8th leading cause of death in the world. It is predicted that by year 2035 about 592 million people will die of diabetes. The economic cost of diabetes seems to have increased worldwide. An average age of onset of diabetes is 42.5 years and could be due to consumption of high sugar and high-calorie diet, low physical activity, genetic susceptibility, and lifestyle. Approximately 8 % children and about 26 % young adults have diabetes mellitus in the world. The results of epidemiological study of type 1 diabetes mellitus (T1D) are presented by demographic, geographic, biologic, cultural, and other factors in human populations. The prevalence of T1D has been increased by 2-5 % worldwide and its prevalence is approximately one in 300 in US by 18 years of age. The epidemiological studies are important to study the role, causes, clinical care, prevention, and treatment of type1 diabetes in pregnant women and their children before and after birth. In this article, causes, diagnosis, symptoms, treatment and medications, and epidemiology of diabetes will be described. PMID:25711186

  10. Ameliorative effects of low dose/low dose-rate irradiation on reactive oxygen species-related diseases model mice

    International Nuclear Information System (INIS)

    Living organisms have developed complex biological system which protects themselves against environmental radiation, and irradiation with proper dose, dose-rate and irradiation time can stimulate their biological responses against oxidative stress evoked by the irradiation. Because reactive oxygen species are involved in various human diseases, non-toxic low dose/low dose-rate radiation can be utilized for the amelioration of such diseases. In this study, we used mouse experimental models for fatty liver, nephritis, diabetes, and ageing to elucidate the ameliorative effect of low dose/low dose-rate radiation in relation to endogenous antioxidant activity. Single irradiation at 0.5 Gy ameliorates carbon tetrachloride-induced fatty liver. The irradiation increases hepatic anti-oxidative system involving glutathione and glutathione peroxidase, suggesting that endogenous radical scavenger is essential for the ameliorative effect of low dose radiation on carbon tetrachloride-induced fatty liver. Single irradiation at 0.5 Gy ameliorates ferric nitrilotriacetate-induced nephritis. The irradiation increases catalase and decreases superoxide dismutase in kidney. The result suggests that low dose radiation reduced generation of hydroxide radical generation by reducing cellular hydroperoxide level. Single irradiation at 0.5 Gy at 12 week of age ameliorates incidence of type I diabetes in non-obese diabetic (NOD) mice through the suppression of inflammatory activity of splenocytes, and resultant apoptosis of β-cells in pancreas. The irradiation activities of superoxide dismutase and catalase, which coordinately diminish intracellular reactive oxygen species. Continuous irradiation at 0.70 mGy/hr from 10 week of age elongates life span, and suppresses alopecia in type II diabetesmice. The irradiation improved glucose clearance without affecting insulin-resistance, and increased pancreatic catalase activity. The results suggest that continuous low dose-rate irradiation protect

    Intracerebral hemorrhage (ICH) is a severe type of stroke causing neurological dysfunction with high mortality rate. Depression is one of the most common complications of ICH. In the present study, the effects of treadmill exercise on ICH-induced depressive symptoms in relation with apoptosis were investigated using rats. ICH rat model was induced by injection of collagenase into the hippocampus using stereotaxic instrument. Open field test for activity and forced swimming test for depressive symptoms were conducted. Apoptosis in the hippocampus was detected using terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling assay, immunohistochemistry for caspase-3, and western blot for Bcl-2 and Bax. Western blot analysis for 5-hydroxy-tryptamine (5-HT, serotonin) and tryptophan hydroxylase (TPH) in the dorsal raphe was also conducted for biomarkers of depression. In the present results, immobility time was increased and climbing time was decreased by induction of ICH and treadmill exercise inhibited immobility time and increased climbing time in ICH rats. DNA fragmentation and caspase-3 expression in the hippocampal dentate gyrus were enhanced by induction of ICH and treadmill exercise suppressed ICH-induced DNA fragmentation and caspase-3 expression. Bax expression in the hippocampus was increased by induction of ICH and treadmill exercise inhibited Bax expression in the ICH rats. Expressions of 5-HT and TPH in the dorsal raphe were decreased by induction of ICH and treadmill exercise increased expressions of 5-HT and TPH in the ICH rats. In the present study, treadmill exercise ameliorated depressive symptoms through inhibiting apoptosis. PMID:27656626

    Full Text Available Background: The aim of this report was to assess the efficacy and safety of a combination of vitamin E, an antioxidant, and Eve Primrose in the management of painful diabetes mellitus (DM neuropathy. Materials and Methods: This was an interventional study that evaluated the efficacy and safety of a combination of vitamin E and Eve Primrose in the management of DM neuropathy. The study was conducted at the Diabetic Centre of the Lagos State University Teaching Hospital, Ikeja. Eighty individuals with type 2 DM who had painful neuropathy were recruited for this study, which took place for a duration of 1 year. The study subjects underwent clinical and biochemical assessment at baseline and were given vitamin E in a dose of 400 mg in combination with Eve Primrose in doses ranging 500-1000 mg/day. They were afterward assessed for relief of symptoms and possible untoward effects after 2 weeks and, thereafter, monthly for 3 months. The main outcome measure was amelioration of symptoms of neuropathy . Results: The mean age and age range of the study subjects were 58.2 years and 37-70 years, respectively. A total of 70 patients (88% of the study population reported relief from neuropathic pains. Clinical parameters were comparable between the responders and non-responders. One characteristic feature of the non-responders was that they all had vibration perception threshold of ≥25 mV, which was indicative of severe neuropathy. Conclusion: The combination of vitamin E and Eve Primrose is beneficial in the management of mild to moderate diabetic neuropathy.

    2015-11-01

    Chronic and slow progression of neuronal death in Parkinson's disease is responsible for an altered neurotransmission of various biogenic amines, such as dopamine. Therefore, an individually different pronounced heterogeneity of motor and nonmotor symptoms characterizes each Parkinson's disease patient. Ideal candidates for the balance of these neurotransmitter deficits are compounds like safinamide with broad mechanisms of action such as reversible monoamine oxidase type B inhibition, blockage of voltage-dependent sodium channels, modulation of calcium channels and of glutamate release. Safinamide is administered one time daily with oral doses ranging from 50 to 100 mg. Safinamide was well tolerated and safe, ameliorated motor symptoms when combined with dopamine agonist only or additional levodopa in clinical trials. Safinamide is a novel instrument for the drug therapy of Parkinson's disease with better safety and tolerability particularly concerning diarrhea than inhibitors of catechol-O-methyltransferase, like entacapone, according to an indirect comparison within a meta-analysis with entacapone.

    Borreria hispida (BHE), a weed of Rubiaceae family, is being used from time immemorial as an alternative therapy for diabetes. To evaluate the scientific background of using BHE as therapy to reduce cardiovascular risk, a group of rats were given BHE for a period of 30 days, whereas control animals were given the vehicle only. The animals were sacrificed, the hearts were isolated, and perfused with buffer. All the hearts were subjected to 30-minute ischemia followed by 2-hour reperfusion. Compared with vehicle-treated rats, BHE-treated rat hearts showed improved post-ischemic ventricular function and exhibited reduced myocardial infarct size and cardiomyocyte apoptosis. The level of cytochrome c expression and caspase 3 activation was also reduced. BHE elevated antiapoptotic proteins Bcl-2 and heme oxygenase-1 and stimulated the phosphorylation of survival protein Akt simultaneously decreasing the apoptotic proteins Bax and Src. In addition, BHE enhanced the protein expression of peroxisome proliferator-activated receptor-gamma, peroxisome proliferator-activated receptor-delta, and Glut-4, probably revealing the antiobese and antidiabetic potential of BHE. These results indicate that treatment with BHE improves cardiac function and ameliorates various risk factors associated with cardiac disease, suggesting that BHE can be considered as a potential plant-based nutraceutical and pharmaceutical agent for the management of cardiovascular diseases.

    Diabetes is the most common cause of neuropathy in United States and neuropathies are the most common complication of diabetes mellitus, affecting up to 50% of patients with type 1 and type 2 diabetes mellitus. Symptoms usually include numbness, tingling, pain, and weakness. Dizziness with postural changes can be seen with autonomic neuropathy. Metabolic, vascular, and immune theories have been proposed for the pathogenesis of diabetic neuropathy. Axonal damage and segmental demyelination can be seen with diabetic neuropathies. Management of diabetic neuropathy should begin at the initial diagnosis of diabetes and mainly requires tight and stable glycemic control.

  18. Knowledge of diabetic complications in patients with diabetes mellitus

    International Nuclear Information System (INIS)

    The prevalence of diabetes mellitus has risen exponentially over the last three decades, with resultant increase in morbidity and mortality mainly due to its complications. Limited data is available regarding the awareness and knowledge about these complications in our population. This study was carried out to evaluate the knowledge of diabetic complications in patients with diabetes mellitus. Methods: This cross-sectional study was conducted in the Medical B Unit of Department of Medicine Khyber Teaching Hospital, Peshawar. All admitted diabetic patients above 15 years of age with duration of diabetes mellitus more than one year were included. Results: Out of the 96 patients questioned, 58 were females and 38 were males. Mean age was 53.29 ± 10.821 years while the mean duration of diabetes mellitus was 9.75 ± 7.729 years. Of the total 76 (79.1%) of the patients were illiterate; 36 (37.50%) had good, 24 (25%) had average and 36 (37.50%) had poor knowledge about diabetic complications. Males and university graduate patients had slightly better knowledge. Between 50-60% patients were aware of different cardiac complications of diabetes mellitus. Awareness regarding other complications was foot ulcer/gangrene 70 (72.91%), poor wound healing 68 (70.83%), stroke 54 (56.25%), renal diseases 64 (66.66%), eye diseases 53 (55.20%), gastroparesis and other gastrointestinal problems 45 (46.87%), diabetic ketoacidosis 55 (57.29%), hypoglycaemia 50 (52.08%), lipid abnormalities 26 (27.08%) and symptoms of diabetic neuropathy ranging from 47-65%. Conclusions: Majority of diabetic patients are unaware of diabetic complications. Therefore, hospital and community based awareness programs should be launched to decrease the morbidity and mortality associated with diabetes mellitus. (author)

    2010-01-01

    OBJECTIVE To examine variables associated with perceived diabetes control compared with an objective measure of glucose control (A1C). RESEARCH DESIGN AND METHODS Beliefs about diabetes were assessed among 334 individuals with diabetes living in a primarily low-income, minority, urban neighborhood. Regression analyses tested associations between disease beliefs and both participants' perceptions of control and actual control (A1C). RESULTS Poorer perceived diabetes control was associated with perceiving a greater impact of diabetes, greater depressive symptoms, not following a diabetic diet, A1C, and a trend toward less exercise. Variables associated with better actual control (A1C) included higher BMI, older age, and not using insulin. CONCLUSIONS Patients' perceptions of their diabetes control are informed by subjective diabetes cues (e.g., perceived impact of diabetes and adherence to a diabetic diet), which are not related to A1C. Clinicians should take into account what cues patients are using to assess their diabetes control. PMID:20067972

    Contrast medium-induced nephropathy (CIN) remains a major cause of iatrogenic, drug-induced renal injury. Recent studies reveal that Breviscapine can ameliorate diabetic nephropathy in mice. Yet it remains unknown if Breviscapine could reduce CIN in diabetic mice. In this study, male C57/BL6J mice were randomly divided into 7 groups: control, diabetes mellitus, CIN, diabetes mellitus+CIN, diabetes mellitus+Breviscapine, CIN+Breviscapine and diabetes mellitus+CIN+Breviscapine. Model of CIN was induced by tail intravenous administration of iopromide and model of diabetes mellitus was induced by Streptozotocin intraperitoneally. Breviscapine was administered intragastrically for 4 weeks. Renal function parameters, kidney histology, markers of renal fibrosis, phosphorylation of protein kinase C/Akt/mitogen activated protein kinases were measured by western blot. We found out that diabetes mellitus aggravated CIN damage. Renal histological analysis showed Breviscapine reduced of renal fibrosis and tubular damage. Breviscapine was also shown markedly to ameliorate CIN fibrotic markers expression, reduced proteinuria and serum creatinine. Furthermore, Breviscapine decreased phosphorylation of PKCβII, Akt, JNK1/2 and p38. Therefore, Breviscapine treatment could ameliorate the development of CIN in diabetic mice, which was partly attributed to its suppression of renal fibrosis via phosphorylation of PKCβII/Akt/JNK1/2/p38 signalling.

    Full Text Available Background: Diabetic neuropathy is an incapacitating disease that afflicts almost 50 percent of patients with diabetes. A late finding in type 1 diabetes, diabetic neuropathy can be an early finding in non insulin-dependent diabetes. Diabetic neuropathies are divided primarily into two groups, sensorimotor and autonomic. Patients may acquire only one type of diabetic neuropathy or may present with combinations of neuropathies, such as autonomic neuropathy or distal symmetric polyneuropathy, the latter of which the most common form. Motor deficits, orthostatic hypotension, silent cardiac ischemia, hyperhidrosis, vasomotor instability, gastroparesis, bladder dysfunction, and sexual dysfunction can also result from diabetic neuropathy. Strict control of blood sugar, combined with proper daily foot care, is essential to avoid the complications of this disorder. With the potential to afflict any part of the nervous system, diabetic neuropathy should be suspected in all patients with type 2 diabetes as well as patients who have had type 1 diabetes for over five years. Although some patients with diabetic neuropathy notice few symptoms, upon physical examination mild to moderately severe sensory loss may be noted by the physician. Idiopathic neuropathy has been known to precede the onset of type 2 diabetes.

    Interleukin-10 (IL-10)-deficient mice spontaneously develop T cell-mediated colitis. Previous reports have shown that Matrine may reduce the symptoms of acute colitis induced by trinitrobenzene sulfonic acid (TNBS). However, whether Matrine impacts chronic colitis remains unknown. In this study, we investigated whether Matrine could limit the symptoms of spontaneously developed colitis and its potential molecular mechanisms. IL-10 deficient mice were given Matrine or a PBS control by oral gavage daily for 4weeks and were euthanized at week 2 or week 4. We measured body weight, colon length and weight, and histological scores. We also evaluated the spontaneous secretion of IL-12/23p40, IFN-γ and IL-17 in colon explant cultures as well as IFN-γ and IL-17 secretion in unseparated mesenteric lymph node (MLN) cells, and assessed IFN-γ, IL-17, IL-1β and IL-6 mRNA expression in colon tissue. In addition, we analyzed the proportions of CD4-positive and CD8-positive cells in unseparated MLN cells. Our results show that Matrine-treated mice exhibited better body weight recovery than controls and that histological scores and spontaneously secreted IL-12/23p40, IFN-γ and IL-17 in colon tissue were significantly decreased in treated mice compared with controls. The proportion of CD4-positive cells of MLNs in treated mice was significantly smaller than that in controls at week 4. Both cytokine production and mRNA expression of IFN-γ and IL-17 were significantly reduced in treated mice compared with controls. Taken together, our results indicate that Matrine may ameliorate spontaneously developed chronic colitis and could be considered as a therapeutic alternative for chronic colitis.

    A preliminary clinical study by our group demonstrated Bushen Yisui Capsule (formerly cal ed Er-huang Formula) in combination with conventional therapy is an effective prescription for the treat-ment of multiple sclerosis. However, its effect on axonal injury during early multiple sclerosis re-mains unclear. In this study, a MOG 35-55-immunized C57BL/6 mouse model of experimental au-toimmune encephalomyelitis was intragastrical y administered Bushen Yisui Capsule. The results showed that Bushen Yisui Capsule effectively improved clinical symptoms and neurological function of experimental autoimmune encephalomyelitis. In addition, amyloid precursor protein expression was down-regulated and microtubule-associated protein 2 was up-regulated. Experimental findings indicate that the disease-preventive mechanism of Bushen Yisui Capsule in experimental autoim-mune encephalomyelitis was mediated by amelioration of axonal damage and promotion of rege-neration. But the effects of the high-dose Bushen Yisui Capsule group was not better than that of the medium-dose and low-dose Bushen Yisui Capsule group in preventing neurological dysfunction.

    Atopic dermatitis (AD) is a common skin disease that greatly worsens quality of life. Thymic stromal lymphopoietin (TSLP) plays a decisive role in the development of AD. The purpose of this study is to examine whether tryptanthrin (TR) would suppress AD through the regulation of TSLP. We analyzed the effect of TR on the level of TSLP from phorbol myristate acetate/calcium ionophore A23187-activated human mast cell line, HMC-1 cells, in 2,4-dinitrofluorobenzene-induced AD-like skin lesions of NC/Nga mice, and in anti-CD3/anti-CD28-stimulated splenocytes. TR significantly suppressed the level of intracellular calcium and the production and mRNA expression of TSLP through the blockade of receptor-interacting protein 2/caspase-1/nuclear factor-κB pathway in the activated HMC-1 cells. TR also significantly suppressed the levels of histidine decarboxylase and IL-1β. Furthermore, TR ameliorated clinical symptoms in the AD model. TR significantly reduced the levels of TSLP, IL-4, IFN-γ, IL-6, TNF-α, thymus and activation-regulated chemokine, and caspase-1 in AD skin lesions. Also, TR significantly reduced the serum levels of histamine and IL-4 in the AD model. Finally, TR significantly inhibited the production of IL-4, IFN-γ, and TNF-α from the stimulated splenocytes. Taken together, TR exhibits the potential to be a therapeutic agent for AD through down-regulation of TSLP. PMID:24295961

    Tranexamic acid (trans-4-aminomethylcyclohexanecarboxylic acid) is a medical amino acid widely used as an anti-inflammatory and a whitening agent. This study examined the effect of tranexamic acid administration in wrinkle formation following skin dryness. We administered tranexamic acid (750mg/kg/day) orally for 20 consecutive days to Naruto Research Institute Otsuka Atrichia (NOA) mice, which naturally develop skin dryness. In these NOA mice, deterioration of transepidermal water loss (TEWL), generation of wrinkles, decrease of collagen type I, and increases in mast cell proliferation and tryptase and matrix metalloproteinase (MMP-1) release were observed. However, these symptoms were improved by tranexamic acid treatment. Moreover, the increase in the β-endorphin level in the blood and the expression of μ-opioid receptor on the surface of fibroblasts increased by tranexamic acid treatment. In addition, when the fibroblasts induced by tranexamic acid treatment were removed, the amelioration effect by tranexamic acid treatment was halved. On the other hand, tranexamic acid treated NOA mice and mast cell removal in tranexamic acid treated NOA mice did not result in changes in the wrinkle amelioration effect. Additionally, the amelioration effect of mast cell deficient NOA mice was half that of tranexamic acid treated NOA mice. These results indicate that tranexamic acid decreased the proliferation of mast cells and increases the proliferation of fibroblasts, subsequently improving wrinkles caused by skin dryness.

    We have shown previously that collagen V (col(V)) autoimmunity is a consistent feature of atherosclerosis in human coronary artery disease and in the Apoe(-/-) mouse model. We have also shown sensitization of Apoe(-/-) mice with col(V) to markedly increase the atherosclerotic burden, providing evidence of a causative role for col(V) autoimmunity in atherosclerotic pathogenesis. Here we sought to determine whether induction of immune tolerance to col(V) might ameliorate atherosclerosis, providing further evidence for a causal role for col(V) autoimmunity in atherogenesis and providing insights into the potential for immunomodulatory therapeutic interventions. Mucosal inoculation successfully induced immune tolerance to col(V) with an accompanying reduction in plaque burden in Ldlr(-/-) mice on a high-cholesterol diet. The results therefore demonstrate that inoculation with col(V) can successfully ameliorate the atherosclerotic burden, suggesting novel approaches for therapeutic interventions. Surprisingly, tolerance and reduced atherosclerotic burden were both dependent on the recently described IL-35 and not on IL-10, the immunosuppressive cytokine usually studied in the context of induced tolerance and amelioration of atherosclerotic symptoms. In addition to the above, using recombinant protein fragments, we were able to localize two epitopes of the α1(V) chain involved in col(V) autoimmunity in atherosclerotic Ldlr(-/-) mice, suggesting future courses of experimentation for the characterization of such epitopes.

    We previously showed that the transcription factor Mafb is essential for podocyte differentiation and foot process formation. Podocytes are susceptible to injury in diabetes, and this injury leads to progression of diabetic nephropathy. In this study, we generated transgenic mice that overexpress Mafb in podocytes using the nephrin promoter/enhancer. To examine a potential pathogenetic role for Mafb in diabetic nephropathy, Mafb transgenic mice were treated with either streptozotocin or saline solution. Diabetic nephropathy was assessed by renal histology and biochemical analyses of urine and serum. Podocyte-specific overexpression of Mafb had no effect on body weight or blood glucose levels in either diabetic or control mice. Notably, albuminuria and changes in BUN levels and renal histology observed in diabetic wild-type animals were ameliorated in diabetic Mafb transgenic mice. Moreover, hyperglycemia-induced downregulation of Nephrin was mitigated in diabetic Mafb transgenic mice, and reporter assay results suggested that Mafb regulates Nephrin directly. Mafb transgenic glomeruli also overexpressed glutathione peroxidase, an antioxidative stress enzyme, and levels of the oxidative stress marker 8-hydroxydeoxyguanosine decreased in the urine of diabetic Mafb transgenic mice. Finally, Notch2 expression increased in diabetic glomeruli, and this effect was enhanced in diabetic Mafb transgenic glomeruli. These data indicate Mafb has a protective role in diabetic nephropathy through regulation of slit diaphragm proteins, antioxidative enzymes, and Notch pathways in podocytes and suggest that Mafb could be a therapeutic target.

    Fatigue continues to be one of the main symptoms that afflict ovarian cancer patients and negatively affects their functional status and quality of life. To manage fatigue effectively, the symptom must be understood from the perspective of patients. We utilized text mining to understand the symptom experiences and strategies that were associated with fatigue among ovarian cancer patients. Through text analysis, we determined that descriptors such as energetic, challenging, frustrating, struggling, unmanageable, and agony were associated with fatigue. Descriptors such as decadron, encourager, grocery, massage, relaxing, shower, sleep, zoloft, and church were associated with strategies to ameliorate fatigue. This study demonstrates the potential of applying text mining in cancer research to understand patients' perspective on symptom management. Future study will consider various factors to refine the results. PMID:27332415

    Individuals with diabetes are at a greater risk for microvascular complications, such as retinopathy, neuropathy, and nephropathy, than are individuals without diabetes. Diabetic neuropathies are complex heterogeneous disorders that include both focal neuropathies and diffuse polyneuropathy. Entrapment neuropathy is an example of a focal neuropathy, while distal symmetric polyneuropathy is the most common type of diffuse polyneuropathy. Entrapment neuropathies are highly prevalent in the diabetic population, but they develop insidiously and progressively, making it difficult to determine their true prevalence. Entrapment neuropathies are suspected to be a more common complication of diabetes than is polyneuropathy. For example, carpal tunnel syndrome (CTS)-one of the most common entrapment neuropathies encountered in patients with diabetes-results from median nerve compression, and has been shown to occur three times more frequently in a diabetic population than in a normal healthy population. Entrapment neuropathies should be actively screened for in patients showing the signs and symptoms of neuropathy, because such patients may require surgical treatment.

    Medicinal plants are efficient ameliorator of oxidative stress associated with diabetes mellitus. In this study, ethyl acetate fraction (SCEE) of Sida cordata was investigated for scientific validation of its folk use in diabetes. Antidiabetic effect of SCEE was confirmed by antihyperglycemic activity in normal glucose loaded and diabetic glucose loaded animals as well as normal off feed animals. Confirmation of antidiabetic activity and toxicity ameliorative role of S. cordata was investigated in a chronic multiple dose treatment study of fifteen days. A single dose of alloxan (120 mg/kg) produced a decrease in insulin level, hyperglycemia, elevated total lipids, triglycerides, and cholesterol and decreased the high-density lipoproteins. Concurrent with these changes, there was an increase in the concentration of lipid peroxidation (TBARS), H2O2, and nitrite in pancreas, liver, and testis. This oxidative stress was related to a decrease in glutathione content (GSH) and antioxidant enzymes. Administration of SCEE for 15 days after diabetes induction ameliorated hyperglycemia, restored lipid profile, blunted the increase in TBARS, H2O2, and nitrite content, and stimulated the GSH production in the organs of alloxan-treated rats. We suggested that SCEE could be used as antidiabetic component in case of diabetes mellitus. This may be related to its antioxidative properties.

    Diabetes mellitus is a group of diseases characterized by high levels of blood glucose resulting from defects in insulin production, insulin action, or both. Diabetes is a serious health concern. The number of cases of diabetes mellitus is estimated to grow at a rate of 50% between 2000 and 2010. There are several types of diabetes: type 1 diabetes, type 2 diabetes, gestational diabetes, and other specific types of diabetes. Beta cell dysfunction plays a key role in the physiopathology of diabetes, even when insulin resistance, which is often present in several diabetes-related diseases, is considered among the causes of hyperglycemic type 2 diabetes. The prolonged hyperglycemia that is peculiar to all kind of diabetes has long term complications on several organs and systems. The diagnosis of diabetes is based on the evaluation of glucose plasma levels performed under fasting conditions or two hours after the oral ingestion of 75 grams of glucose. Currently, achieving and maintaining normal plasma levels of glucose are the aims of therapy for both type 1 and type 2 diabetes. Particularly, the therapy for type 1 diabetes is based on the administration of insulin, whereas that of type 2 diabetes changes over the time: diet and physical activity are the first treatments; oral hypoglycemic drugs are used as a second therapeutic step; and the administration of insulin is the last therapeutic option. The principal therapeutic innovation of the past ten years is represented by the tight and flexible control of glucose plasma level obtained by using the insulin analogues produced by recombinant DNA technology.

    Konynenburg, R.A. van; Farmer, J.C.

    1999-11-09

    A fuse and filter arrangement is described for limiting and ameliorating electrode shorting in capacitive deionization water purification systems utilizing carbon aerogel, for example. This arrangement limits and ameliorates the effects of conducting particles or debonded carbon aerogel in shorting the electrodes of a system such as a capacitive deionization water purification system. This is important because of the small interelectrode spacing and the finite possibility of debonding or fragmentation of carbon aerogel in a large system. The fuse and filter arrangement electrically protect the entire system from shutting down if a single pair of electrodes is shorted and mechanically prevents a conducting particle from migrating through the electrode stack, shorting a series of electrode pairs in sequence. It also limits the amount of energy released in a shorting event. The arrangement consists of a set of circuit breakers or fuses with one fuse or breaker in the power line connected to one electrode of each electrode pair and a set of screens of filters in the water flow channels between each set of electrode pairs.

    Full Text Available Abstract Background Apathy is frequently observed in numerous neurological disorders, including Alzheimer's and Parkinson's, as well as neuropsychiatric disorders including schizophrenia. Apathy is defined as a lack of motivation characterized by diminished goal-oriented behavior and self-initiated activity. This study evaluated a chronic restraint stress (CRS protocol in modeling apathetic behavior, and determined whether administration of an anticholinesterase had utility in attenuating CRS-induced phenotypes. Methods We assessed behavior as well as regional neuronal activity patterns using FosB immunohistochemistry after exposure to CRS for 6 h/d for a minimum of 21 d. Based on our FosB findings and recent clinical trials, we administered an anticholinesterase to evaluate attenuation of CRS-induced phenotypes. Results CRS resulted in behaviors that reflect motivational loss and diminished emotional responsiveness. CRS-exposed mice showed differences in FosB accumulation, including changes in the cholinergic basal forebrain system. Facilitating cholinergic signaling ameliorated CRS-induced deficits in initiation and motivational drive and rescued immediate early gene activation in the medial septum and nucleus accumbens. Conclusions Some CRS protocols may be useful for studying deficits in motivation and apathetic behavior. Amelioration of CRS-induced behaviors with an anticholinesterase supports a role for the cholinergic system in remediation of deficits in motivational drive.

    The detection of subclinical abnormalities in cerebral blood flow could be of great value in identifying diabetic patients at risk of stroke. The aim of this study was to assess the contribution of semiquantified post-acetazolamide technetium-99m hexamethylpropylene amine oxime single-photon emission tomography ({sup 99m}Tc-HMPAO SPET) in 15 diabetic patients with no clinical history of central neurological disease. After baseline {sup 99m}Tc-HMPAO SPET, a second SPET scan was acquired after activation of the cerebrovascular reserve (CVR) with an injection of 1 g of acetazolamide (post-ACZ SPET). Semiquantitative analysis was made in 16 regions of interest (ROIs) drawn for each of the three supratentorial slices selected, and in two ROIs in the infratentorial slice. The CVR was calculated in each ROI by subtracting the decay-corrected baseline images from those obtained in the post-ACZ SPET and expressed as the percent increase in the average counts between the two scans. Baseline perfusion and CVR values in the study group were compared with the corresponding values in a control group. Of 750 cortical ROIs studied, 332 showed a decreased CVR (44.3%). The baseline perfusion SPET study showed hypoperfusion in 65 ROIs (8.6%) and hyperperfusion in 56 (7.4%). Of the 65 hypoperfused regions, 66.2% had a normal CVR and 33.8% had a decreased CVR, whereas of the 56 hyperperfused regions, 51.8% had a CVR within normal limits and 48.2% showed a decreased CVR. In conclusion, in comparison with baseline {sup 99m}Tc-HMPAO SPET, the ACZ activation test provided additional information in the study of cerebrovascular impairment, and allowed characterisation of the subclinical abnormalities in the population studied. The technique may therefore prove useful in evaluating future preventive strategies for stroke in diabetic patients. (orig.)

    Full Text Available The aim of the present study was to evaluate the effect of melatonin as an antioxidant on spatial navigation memory in male diabetic rats. Thirty-two male white Wistar rats weighing 200 ± 20 g were divided into four groups, randomly: control, melatonin, diabetic and melatonin-treated diabetic. Experimental diabetes was induced by intraperitoneal injection of 50 mg kg-1 streptozotocin. Melatonin was injected (10 mg kg-1 day-1, ip for 2 weeks after 21 days of diabetes induction. At the end of administration period, the spatial navigation memory of rats was evaluated by cross-arm maze. In this study lipid peroxidation levels, glutathione-peroxidase and catalase activities were measured in hippocampus. Diabetes caused to significant decrease in alternation percent in the cross-arm maze, as a spatial memory index, compared to the control group (p < 0.05, whereas administration of melatonin prevented the spatial memory deficit in diabetic rats. Also melatonin injection significantly increased the spatial memory in intact animals compared to the control group (p < 0.05. Assessment of hippocampus homogenates indicated an increase in lipid peroxidation levels and a decrease in GSH-Px and CAT activities in the diabetic group compared to the control animals, while melatonin administration ameliorated these indices in diabetic rats. In conclusion, diabetes induction leads to debilitation of spatial navigation memory in rats, and the melatonin treatment improves the memory presumably through the reduction of oxidative stress in hippocampus of diabetic rats.

    2015-07-01

    As the number of diagnoses of diabetes mellitis continues to increase, so does the incidence of diabetic complications, such as gastroparesis. The current case report examines the effect of osteopathic manipulative treatment (OMT) on the symptoms of diabetic gastroparesis in a patient with type 1 diabetes mellitus. After a prescribed regimen of OMT, the patient's Gastroparesis Cardinal Symptom Index score improved from 13 to 8, and his hospitalization stays decreased from once every 6 to 8 weeks to once in 6 months. After 6 sessions of OMT, the patient experienced a reduction in and subsequent relief of diabetic gastroparesis symptoms and improved quality of life. The role of OMT needs to be further investigated as a cost-effective adjunctive treatment for patients with diabetic gastroparesis.

    Full Text Available In coffee plantation, solid waste of coffee pulp is usually collected as heap nearby processing facilities for several months prior being used as compost. The practice is leading to the formation of odor and liquid which contaminate the environment. Experiments to evaluate the effect of natural soil ameliorant derived from coffee pulp and minerals were conducted at The Indonesian Coffee and Cocoa Research Institute in Jember, East Java. The experiments were intended to optimize the use of coffee pulp to support farming sustainability and minimize negative impacts of solid waste disposal originated from coffee cherry processing. Prior to applications, coffee pulp was hulled to organic paste. The paste was then mixed with 10% minerals (b/b. Composition of the minerals was 50% zeolite and 50% rock phosphate powder. The ameliorant was characterized for their physical and chemical properties. Agronomic tests were conducted on coffee and cocoa seedling. The experiments were arranged according to Randomized Completely Design with 2 factors, consisted of natural ameliorant and inorganic fertilizer respectively. Natural ameliorant derived from coffee pulp was applied at 6 levels: 0, 30, 60, 90, 120 and 150 g dry ameliorant/seedling of 3 kg soil, equivalent to 0, 1, 2, 3, 4 and 5% (b/b of ameliorant respectively. Inorganic fertilizer was applied at 2 levels: 0 and 2 g fertilizer/application of N-P-K compound fertilizer of 15-15-15 respectively. The inorganic fertilizer was applied 4 times during nursery of coffee and cocoa. The result of the experiment indicated that coffee pulp may be used as natural soil ameliorant. Composition of ameliorant of 90% coffee pulp and 10% of minerals has good physical and chemical characteristics for soil amelioration. The composition has high water holding capacity; cations exchange capacity, organic carbon and phosphorus contents which are favorable to increase soil capacity to support plant growth.

    Autosomal dominant neurohypophyseal diabetes insipidus (ADNDI) is a rare variant of idiopathic central diabetes insipidus. Several different mutations in the human vasopressin-neurophysin II (AVP-NP II) gene have been described. We studied nine family members from three generations of an ADNDI pedigree at the clinical, morphological, and molecular levels. AVP concentrations were measured during diagnostic fluid restriction tests. Coronal and sagittal high resolution T1-weighted images of the pituitary were obtained from affected and healthy family members. PCR was used to amplify the AVP-NP II precursor gene, and PCR products were directly sequenced. Under maximal osmotic stimulation, AVP serum levels were close to or below the detection limit in affected individuals. Magnetic resonance imaging studies revealed the characteristic hyperintense ({open_quotes}bright spot{close_quotes}) appearance of the posterior pituitary in two healthy family members. This signal was absent in all four ADNDI patients examined. The coding sequences of AVP and its carrier protein, neurophysin II, were normal in all family members examined. Affected individuals showed a novel single base deletion (G 227) in the translation initiation codon of the AVP-NP II signal peptide on one allele. The mutation in the AVP-NP II leader sequence appears to be responsible for the disease in this kindred, possibly by interfering with protein translocation. The absence of the hyperintense posterior pituitary signal in affected individuals could reflect deficient posterior pituitary function. 56 refs., 4 figs., 3 tabs.

    Full Text Available Background: People diagnosed with diabetes mellitus are increasing in sub-Saharan Africa and prompt care seeking depends on perceptions of the illness. Objective: The objective was to explore perceptions of diabetes in rural areas.Method: We conducted a qualitative, explorative and descriptive study in rural eastern Uganda. Eight focus group discussions with community members were conducted. Community members were presented with a story about a person with diabetes symptoms and their perceptions of the diagnosis and treatment elicited. Four focus group discussions with people with diabetes and seven key informant interviews with health workers were conducted. Respondents were asked how the community interpreted symptoms of diabetes, its causes and whether it was curable. Manifest content analysis was used.Results: Some respondents thought people with diabetes symptoms had HIV or were bewitched. Causes of diabetes mentioned included consuming too much fatty food. Some respondents thought diabetes is transmitted through air, sharing utensils with or sitting close to people with diabetes. Some respondents thought that diabetes could heal fast whilst others thought it was incurable. Conclusion: Misdiagnosis may cause delay in seeking proper care. Preventive programmes could build on people’s thinking that too much fatty food causes diabetes to promote diets with less fat. The perception of diabetes as a contagious disease leads to stigmatisation and affects treatment seeking. Seeing diabetes as curable could create patient expectations that may not be fulfilled in the management of diabetes. Rural communities would benefit from campaigns creating awareness of prevention, symptoms, diagnosis and management of diabetes.

    2014-01-01

    Full Text Available Background: Diabetes Mellitus (DM is a common but complex metabolic disorder affecting various systems in the body. Oral cavity is no exception as this chronic condition exerts a huge impact on oral health. Salivary dysfunction has been reported to be a frequent oral complication in Type 2 diabetics which in turn leads to an array of oral complications because oral health is to a greater extent dependent on the quality and quantity of saliva. Aim: The aim of the present study was to evaluate and compare the salivary flow rate and prevalence of subjective symptoms of xerostomia in diabetics and non-diabetics. Materials and Methods: The study was conducted on 100 type 2 diabetic patients and 50 non-diabetic subjects. Random non-fasting plasma glucose and glycosylated hemoglobin levels were used to determine the diabetic status of the individuals. Unstimulated saliva was collected using “Spit technique”. Stimulated saliva was collected using 2% citric acid. Unstimulated and Stimulated Salivary Flow Rate (USFR and SSFR was calculated for every patient and expressed as ml/min. Xerostomia was evaluated using a multi-item inventory comprising 19 questions. Results: In our study, both whole unstimulated and stimulated salivary flow rates were decreased in diabetics compared to non-diabetics and this difference was statistically significant (p = 0.000. A greater percentage of diabetic patients perceived xerostomia symptoms compared to non-diabetics. Conclusion: Type 2 diabetics have higher prevalence of xerostomia and significantly reduced salivary flow rate compared to non-diabetics. Alterations in salivary flow create an imbalance in the homeostasis of oral environment leading to spectrum of oral ailments in these individuals

    GM2 gangliosidoses, including Tay-Sachs and Sandhoff diseases, are neurodegenerative lysosomal storage diseases that are caused by deficiency of β-hexosaminidase A, which comprises an αβ heterodimer. There are no effective treatments for these diseases; however, various strategies aimed at restoring β-hexosaminidase A have been explored. Here, we produced a modified human hexosaminidase subunit β (HexB), which we have termed mod2B, composed of homodimeric β subunits that contain amino acid sequences from the α subunit that confer GM2 ganglioside-degrading activity and protease resistance. We also developed fluorescent probes that allow visualization of endocytosis of mod2B via mannose 6-phosphate receptors and delivery of mod2B to lysosomes in GM2 gangliosidosis models. In addition, we applied imaging mass spectrometry to monitor efficacy of this approach in Sandhoff disease model mice. Following i.c.v. administration, mod2B was widely distributed and reduced accumulation of GM2, asialo-GM2, and bis(monoacylglycero)phosphate in brain regions including the hypothalamus, hippocampus, and cerebellum. Moreover, mod2B administration markedly improved motor dysfunction and a prolonged lifespan in Sandhoff disease mice. Together, the results of our study indicate that mod2B has potential for intracerebrospinal fluid enzyme replacement therapy and should be further explored as a gene therapy for GM2 gangliosidoses.

    The chronic decrease of brain amyloid-β (Aβ) peptides is an emerging therapeutic for Alzheimer's disease, but no such treatment has achieved clinical validation yet. In vivo, some brain proteases, including neprilysin, possess the ability of degrading Aβ and experimental data suggest their exploitation in strategies to reduce cerebral Aβ concentration. Previous studies have shown that pharmacologic doses of gamma-hydroxybutyrate (sodium oxybate or Xyrem) induce histone deacetylases (HDACs) inhibition and neprilysin gene expression. Here, we demonstrate that brain neprilysin overexpression induced in vivo by repeated gamma-hydroxybutyrate autoadministration reduces cerebral Aβ contents and prevents cognitive deficits in APPSWE mice. Oral gamma-hydroxybutyrate also counteracted phosphoramidon-induced brain neprilysin inhibition and Aβ accumulation. HDACs activities in SH-SY5Y cells were inhibited by gamma-hydroxybutyrate which did not affect amyloid peptide precursor intracellular domain. Together, our results suggest that gamma-hydroxybutyrate, acting via HDAC inhibition, upregulates neprilysin to reduce Aβ level and related memory deficits. Because gamma-hydroxybutyrate doses used herein are clinically relevant, our data suggest that chronic oral administration of gamma-hydroxybutyrate or its analogs may be considered for strategies against presymptomatic or established Alzheimer's disease.

  4. Preventive Effect of Boiogito on Metabolic Disorders in the TSOD Mouse, a Model of Spontaneous Obese Type II Diabetes Mellitus

    Full Text Available “Boiogito” is a Kampo preparation which has been used since ancient times in patients with obesity of the “asthenic constitution” type, so-called “watery obesity”, and its effect has been recognized clinically. In this study, we investigated the anti-obesity effect of Boiogito in the TSOD (Tsumura Suzuki Obese Diabetes mouse, a model of spontaneous obese type II diabetes mellitus. Boiogito showed a significant anti-obesity effect in TSOD mice by suppressing body weight gain in a dosage-dependent manner. In addition, Boiogito showed significant ameliorative effects on features of metabolic syndrome such as hyperinsulinemia, fasting hyperglycemia and abnormal lipid metabolism. Regarding lipid accumulation in TSOD mice, Boiogito showed a significant suppressive effect on accumulation of subcutaneous fat, but the effect on the visceral fat accumulation that constitutes the basis of metabolic syndrome was weak, and the suppressive effect on insulin resistance was also weak. Furthermore, Boiogito did not alleviate the abnormal glucose tolerance, the hypertension or the peripheral neuropathy characteristically developed in the TSOD mice. In contrast, in the TSNO (Tsumura Suzuki Non-Obesity mice used as controls, Boiogito suppressed body weight gain and accumulation of subcutaneous and visceral fat. The above results suggested that Boiogito is effective as an anti-obesity drug against obesity of the “asthenic constitution” type in which subcutaneous fat accumulates, but cannot be expected to exert a preventive effect against various symptoms of metabolic syndrome that are based on visceral fat accumulation.

    Full Text Available Introduction. The aim of this study was to point out some dilemmas about the existence and pathogenesis of primary diabetic osteopathy as a separate entity, based on currently available studies. Expert disagreements are present not only about the occurrence of generalized osteopathy with diabetic disease, but also about direct relationship between metabolic diabetes control and bone metabolism and influence of disease duration and sex on bone changes. Pathogenesis of diabetic osteopathy Decreased bone formation is the basic mechanism leading to decreased bone mass. Biochemical markers showed no clear connection with bone density measurement. Insulin and insulin-like growth factor (IGF affect bone metabolism. Osteopathy in patients with diabetic disease-type 1 Some clinical studies have shown that patients with diabetic disease-type 1 have a mild decrease in bone mass, while others have not presented such results. Osteopathy in patients with diabetic disease-type2 In patients with diabetic disease-type 2 the risk for osteopathy is even less defined. Patients treated with oral hypoglycemics present with higher decrease of bone mass has than patients treated with insulin therapy. This could partly be explained by anabolic effects of insulin on bones. Bone fractures in patients with diabetic disease Literature data are contradictory concerning the occurrence of bone fractures in diabetic patients. A survey of bone fracture occurrence in diabetic patients was performed in "Veljko Vlahović Medical Center" in Vrbas and it included a group of 100 patients with diabetic disease. The results show that 12 patients had some fractures: mostly females in postmenopause, aged and with secondary insulin-dependent diabetes and most frequently arm fractures. Considering contradictory literature data, further longitudinal studies are necessary. .

    Diabetes is a chronic childhood condition, presenting with raised blood sugar. The classic signs and symptoms may not be evident early on, especially in younger children, so it is important that health professionals maintain a high level of suspicion about diabetes when presented with non-specific symptoms eg. abdominal pain, lethargy, delayed wound healing, etc. When a child is first diagnosed, not only does the young person and their family have to cope with the emotional impact of diagnosis, but they also need to understand the huge amounts of information given to them. Health care practitioners provide essential support in helping them come to terms with, as well as manage, this condition. In this article we explain how diabetes is diagnosed and some of the common issues that arise in the ongoing care of the young person, with a particular emphasis on managing daily challenges. Community practitioners play a vital role in detecting symptoms early and making a referral, as well as supporting children with diabetes post-diagnosis in the community.

    2007-02-01

    Full Text Available The goal of this retrospective study was to establish differences in clinical picture, biochemical parametres and precipitating factors in patiens with diabetic ketoacidosis in type 1 and type 2 diabetes. A total number of 25 patients was hospitalised in the Intensive Case Unit of the Department for Internal Diseases of the Cantonal Hospital in Zenica in the period of 14 months. Most patients had type 1 diabetes whose ketoacidosis showed symptoms of vomiting, stomachache and it was most often caused by a discontinued application of insulin or an infection. In patients with type 2 diabetes an inadequate regulation of glycemia had been noticed before hospitalisation and diabetic ketoacidosis was manifested by polyuria, polyphagia, polydipsia and weight loss. Precipitating factor in most patients with type 2 diabetes was an infection. In addition, a significant number of patients were newly discovered diabetics whose precipitating factor in most cases could not be found and the symptoms of the disease correspond to insulin dependent patients. The observed biochemical parameters did not show statistically significant differences between the groups of patients suffering from different types of diabetes. This study has shown that diabetic ketoacidosis can occur in type 2 diabetes. DKA can be prevented by education of patients, improvement of health care as well as improved communication between patients and doctors of family medicine.

    Objective: To evaluate the efficacy and safety of trigonella foenum-graecum L. total saponins (TFGs) in combination with sulfonylureas (SU) in the treatment of patients with type 2 diabetes mellitus (T2DM) not well controlled by SU alone. Methods: Sixty-nine T2DM patients whose blood glucose levels were not well controlled by oral sulfonylureas hypoglycemic drug were randomly assigned to the treated group (46 cases) and the control group (23 cases), and were given TFGs or placebo three times per day, 6 pills each time for 12 weeks, respectively. Meanwhile, the patients continued taking their original hypoglycemic drugs. The following indexes, including effects on traditional Chinese medicine (TCM) symptoms, fast blood glucose (FBG), 2-h post-prandial blood glucose (2h PBG), glycosylated hemoglobin (HbA1c), clinical symptomatic quantitative scores (CSQS), body mass index (BMI), as well as hepatic and renal functions, were observed and compared before and after treatment. Results: The efficacy on TCM symptoms was obviously better in the treated group than that in the control group (P0.05). Conclusion: The combined therapy of TFGs with sulfonylureas hypoglycemic drug could lower the blood glucose level and ameliorate clinical symptoms in the treatment of T2DM, and the therapy was relatively safe.

  9. Exercise Ameliorates High Fat Diet Induced Cardiac Dysfunction by Increasing Interleukin 10

    Full Text Available Increasing evidence suggests that a sedentary lifestyle and a high fat diet (HFD leads to cardiomyopathy. Moderate exercise ameliorates cardiac dysfunction, however underlying molecular mechanisms are poorly understood. Increased inflammation due to induction of pro-inflammatory cytokine such as tumor necrosis factor-alpha (TNF-α and attenuation of anti-inflammatory cytokine such as interleukin10 (IL-10 contributes to cardiac dysfunction in obese and diabetics. We hypothesized that exercise training ameliorates HFD- induced cardiac dysfunction by mitigating obesity and inflammation through upregulation of IL-10 and downregulation of TNF-α. To test this hypothesis, eight week old, female C57BL/6J mice were fed with HFD and exercised (swimming 1hr/day for 5 days/week for eight weeks. The four treatment groups: normal diet (ND, HFD, HFD + exercise (HFD + Ex and ND + Ex were analyzed for mean body weight, blood glucose level, TNF-α, IL-10, cardiac fibrosis by Masson Trichrome, and cardiac dysfunction by echocardiography. Mean body weights were increased in HFD but comparatively less in HFD + Ex. The level of TNF-α was elevated and IL-10 was downregulated in HFD but ameliorated in HFD + Ex. Cardiac fibrosis increased in HFD and was attenuated by exercise in the HFD + Ex group. The percentage ejection fraction and fractional shortening were decreased in HFD but comparatively increased in HFD + Ex. There was no difference between ND and ND + Ex for the above parameters except an increase in IL-10 level following exercise. Based on these results, we conclude that exercise mitigates HFD- induced cardiomyopathy by decreasing obesity, inducing IL-10, and reducing TNF-α in mice.

    Full Text Available Today diabetes mellitus has emerged as a major healthcare problem throughout the world. It has recently broken the age barrier and has been diagnosed in younger people also. Sustained hyperglycemia is associated with many complications including male reproductive dysfunctions and infertility. Numerous medicinal plants have been used for the management of the diabetes mellitus in various traditional system of medicine and in folklore worldwide as they are a rich source of bioactive phytoconstituents, which lower blood glucose level and/or also act as antioxidants resulting in the amelioration of oxidative-stress-induced diabetic complications. The present review describes the ameliorative effects of medicinal plants or their products, especially on male reproductive dysfunctions, in experimental diabetic animal models.

    Objective: To elucidate the mechanism of action of methanolic extract of Carissa carandas fruits (MCCF) in attenuation of diabetic nephropathy using gentamicin induced nephrotoxicity model.Methods:Extract was daily administered to Sprague Dawley rats at doses of 100, 200 and 400 mg/kg for 8 days along with intramuscular injection of gentamicin (80 mg/kg). After completion of the study, serum was analyzed for blood urea nitrogen, albumin and creatinine; urine (24 h) was analyzed for albumin and creatinine. Kidney was evaluated for its biochemical and morphological changes. Results: Extract at doses of 200 and 400 mg/kg significantly normalized the nephrotoxic biomarkers in serum and urine and increased the kidney antioxidant activities which were altered due to gentamicin toxicity. The histological findings reveal that MCCF was capable of protecting the kidney against gentamicin toxicity. Conclusions: Extract ameliorated oxidative stress generated by gentamicin administration, which is one of the mechanisms for its preventive action against diabetic nephropathy.

    This work was designed to investigate the effects of levocetirizine, a histamine H1 receptor antagonist, on diabetes-induced nephropathy and vascular disorder, in comparison to an angiotensin II receptor antagonist, losartan. Diabetes was induced in male Sprague Dawley rats by a single intraperitoneal injection of streptozotocin (50mg/kg). Diabetic rats were divided into three groups; diabetic, diabetic-levocetirizine (0.5mg/kg/day) and diabetic-losartan (25mg/kg/day). Treatments were started two weeks following diabetes induction and continued for additional eight weeks. At the end of the experiment, urine was collected and serum was separated for biochemical measurements. Tissue homogenates of kidney and aorta were prepared for measuring oxidative stress, nitric oxide (NO), transforming growth factor-β1 (TGF-β1) and tumor necrosis factor-α (TNF-α). Moreover, histological analyses were conducted and aortic vascular reactivity was investigated. Levocetirizine improved renal function in diabetic rats (evidenced by mitigation of diabetes-induced changes in kidney to body weight ratio, serum albumin, urinary proteins and creatinine clearance). Moreover, levocetirizine attenuated the elevated renal levels of TNF-α and TGF-β1, ameliorated renal oxidative stress and restored NO bioavailability in diabetic kidney. These effects were comparable to or surpassed those produced by losartan. Moreover, levocetirizine, similar to losartan, reduced the enhanced responsiveness of diabetic aorta to phenylephrine. Histological evaluation of renal and aortic tissues further confirmed the beneficial effects of levocetirizine on diabetic nephropathy and revealed a greater attenuation of diabetes-induced vascular hypertrophy by levocetirizine than by losartan. In conclusion, levocetirizine may offer comparable renoprotective effect to, and possibly superior vasculoprotective effects than, losartan in streptozotocin-diabetic rats. PMID:27012991

    2014-11-01

    Full Text Available Accidents are a major public health concern, resulting in an estimated 1.2 million deaths and 50 million injuries worldwide each year specifically, the relationships between drivers' characteristics and road accidents are not fully understood. Many factors are involved in the accident occurrence at construction site. Some important elements that create a significant portion of accidents include: safety management error, poor training programs, human element, act of god, outdated procedure and no clear monitoring policy. Although some of these items are inevitable, but the occurrence of the largest part can be prevented. Therefore, for ameliorating the safety in a project each of these items should be analyzed and a practical approach introduced. In general, near miss, incident and accident are three dependent levels that mainly lead to injury. Risk and hazard are allocated in first level which means near miss, therefore, no on-time identification of hazard and risk causes to create incident and preventing accident in incident stage is unavoidable.

  15. Riboflavin ameliorates cisplatin induced toxicities under photoillumination.

    Directory of Open Access Journals (Sweden)

    Iftekhar Hassan

    Full Text Available BACKGROUND: Cisplatin is an effective anticancer drug that elicits many side effects mainly due to induction of oxidative and nitrosative stresses during prolonged chemotherapy. The severity of these side effects consequently restricts its clinical use under long term treatment. Riboflavin is an essential vitamin used in various metabolic redox reactions in the form of flavin adenine dinucleotide and flavin mononucleotide. Besides, it has excellent photosensitizing property that can be used to ameliorate these toxicities in mice under photodynamic therapy. METHODS AND FINDINGS: Riboflavin, cisplatin and their combinations were given to the separate groups of mice under photoilluminated condition under specific treatment regime. Their kidney and liver were excised for comet assay and histopathological studies. Furthermore, Fourier Transform Infrared Spectroscopy of riboflavin-cisplatin combination in vitro was also conducted to investigate any possible interaction between the two compounds. Their comet assay and histopathological examination revealed that riboflavin in combination with cisplatin was able to protect the tissues from cisplatin induced toxicities and damages. Moreover, Fourier Transform Infrared Spectroscopy analysis of the combination indicated a strong molecular interaction among their constituent groups that may be assigned for the protective effect of the combination in the treated animals. CONCLUSION: Inclusion of riboflavin diminishes cisplatin induced toxicities which may possibly make the cisplatin-riboflavin combination, an effective treatment strategy under chemoradiotherapy in pronouncing its antineoplastic activity and sensitivity towards the cancer cells as compared to cisplatin alone.

    2012-01-01

    Insulin resistance (IR)is defined as decreased sensitivity and/or responsiveness to insulin that promote glucose disposal.A growing body of clinical and epidemiologic evidence indicates that essential hypertension and IR often coexist[1].Approximately 50 percent of patients with hypertension can be considered to have IR and hyperinsulinemia[1].This inextricable linkage between hypertension and IR has been identified to increase the prevalence of cardiovascular disease (CVD)and new onset of type Ⅱ diabetes that is the major cause of morbidity and mortality in this clinical syndrome[2].However,the driving force linking IR and hypertension remains to be fully elucidated.

    Liu, Yanlong; Dong, Man; Yang, Ziyu; Pan, Siyi

    2016-08-01

    This study was performed to investigate the anti-diabetic effect of citrus pectin in type 2 diabetic rats and its potential mechanism of action. The results showed that fasting blood glucose levels were significantly decreased after 4 weeks of citrus pectin administration. Citrus pectin improved glucose tolerance, hepatic glycogen content and blood lipid levels (TG, TC, LDL-c and HDL-c) in diabetic rats. Citrus pectin also significantly reduced insulin resistance, which played an important role in the resulting anti-diabetic effect. Moreover, after the pectin treatment, phosphorylated Akt expression was upregulated and GSK3β expression was downregulated, indicating that the potential anti-diabetic mechanism of citrus pectin might occur through regulation of the PI3K/Akt signaling pathway. Together, these results suggested that citrus pectin could ameliorate type 2 diabetes and potentially be used as an adjuvant treatment.

    Purple coneflower plants (Echinacea purpurea) were placed into open-top chambers (OTCs) for 6 and 12 weeks in 2003 and 2004, respectively, and exposed to charcoal-filtered air (CF) or twice-ambient (2x) ozone (O{sub 3}) in 2003, and to CF, 2x or non-filtered (NF), ambient air in 2004. Plants were treated with ethylenediurea (EDU) weekly as a foliar spray. Foliar symptoms were observed in >95% of the plants in 2x-treated OTCs in both years. Above-ground biomass was not affected by 2x treatments in 2003, but root and total-plant biomass decreased in 2004. As a result of higher concentrations of select cell wall constituents (% ADF, NDF and lignin) nutritive quality was lower for plants exposed to 2x-O{sub 3} in 2003 and 2004 (26% and 17%, respectively). Significant EDU x O{sub 3} interactions for concentrations of cell wall constituents in 2003 indicated that EDU ameliorated O{sub 3} effects on nutritive quality. Interactions observed in 2004 were inconsistent. - EDU can potentially ameliorate negative effects of O{sub 3} on nutritive quality in purple coneflower.

    Full Text Available Cancer cachexia, which is characterized by decreased food intake, weight loss and systemic inflammation, increases patient’s morbidity and mortality. We previously showed that rikkunshito (RKT, a Japanese traditional herbal medicine (Kampo, ameliorated the symptoms of cancer cachexia through ghrelin signaling-dependent and independent pathways. To investigate other mechanisms of RKT action in cancer cachexia, we performed metabolome analysis of plasma in a rat model bearing the Yoshida AH-130 hepatoma. A total of 110 metabolites were detected in plasma and RKT treatment significantly altered levels of 23 of those metabolites in cachexia model rats. Among them, glucarate, which is known to have anticarcinogenic activity through detoxification of carcinogens via inhibition of β-glucuronidase, was increased in plasma following administration of RKT. In our AH-130 ascites-induced cachexia rat model, administration of glucarate delayed onset of weight loss, improved muscle atrophy, and reduced ascites content. Additionally, glucarate reduced levels of plasma interferon-γ (IFN-γ in tumor-bearing rats and was also found to suppress LPS-induced IFN-γ expression in splenocytes in vitro. These results suggest that glucarate has anti-inflammatory activity via a direct effect on immune host cells and suggest that RKT may also ameliorate inflammation partly through the elevation of glucarate in plasma.

    Full Text Available Background. The neural stem cells (NSCs migrate to the damaged sites in multiple sclerosis (MS and in experimental autoimmune encephalomyelitis (EAE. However, the differentiation into neurons or oligodendrocytes is blocked. Epidermal growth factor (EGF stimulates NSC proliferation and mobilization to demyelinated lesions but also induces astrogenesis and glial scar. Objective. To examine the clinical and histopathological effects of EGF neutralization on EAE. Methods. EAE-induced SJL mice were intravenously treated with either anti-EGF neutralizing antibody (Ab or isotype control or PBS. On day 9 after immunization, 3 mice of each group were daily treated for 9 days with BrdU and then sacrificed for immunohistochemical analysis. Results. Treatment with anti-EGF Ab significantly ameliorated EAE symptoms during the second relapse. Anti-EGF Ab induced a shift from BrdU+GFAP+ NSCs to BrdU+DCX+ neuroblasts in the subventricular zone (SVZ, increased BrdU+NeuN+ neurons in the granular cell layer of the dentate gyrus, and increased BrdU+O4+ oligodendrocytes in the SVZ. There was no change in the inflammatory infiltrates in response to anti-EGF Ab. Conclusions. Therapy with anti-EGF Ab ameliorates EAE via induction of neurogenesis and oligodendrogenesis. No immunosuppressive effect was found. Further investigation is needed to support these notions of beneficial effect of anti-EGF Ab in MS.

    We investigated whether the oral administration of Bifidobacterium longum BB536 could ameliorate influenza virus (IFV) infection in a mice model. Mice were orally administrated BB536 or saline for 2 weeks and then infected with IFV. Orally administered BB536 significantly alleviated symptoms, reduced the loss of body weight, and inhibited viral proliferation in the lungs relative to the control group findings. Histopathological findings in the lungs were improved in the BB536 group compared to control group findings. There was no significant difference in the levels of interleukin-6 (IL-6), interferon-γ (IFN-γ), IL-10 and IL-12p40 in the lungs between the groups, but the levels of IL-6 and IFN-γ were lower (p=0.076, 0.103, respectively) in the BB536 group compared with those of control group. The levels of IL-6 and IL-10 correlated significantly with the values of weight loss, and the levels of IFN-γ correlated with the virus titers in the lungs. These results suggested the potential of the oral administration of BB536 in ameliorating IFV infection and the possible involvement of anti-inflammatory effects of BB536 in the anti-infection effects against IFV.

    The prevalence of diabetes increase in the elderly. Ageing is one of the most important factors contributing to development of glucose intolerance (insuline resistance). NHANES II data showed that in the poppulation over 65 years 18.7% has got overt diabetes and 22.8% glucose intolerance. Similar data were obtained among ageing inhabitants of the city of Bialystok (downtown). The criteria of diagnosis of diabetes in the elderly are the same like in the younger population. However, in the elderly the clinical symptoms are not characteristic and scanty (limited). The period without symptoms is long. Very often, the diabetes is diagnosed for the first time in patient with the heart infarct, brain stroke, diabetic foot or even hyperosmolar coma. There may occur two critical situations in the elderly diabetic persons, namely non-ketotic hyperosmolar coma and hypoglycameia. The non-ketotic hyperosmolar coma is a result of a considerable elevation in the blood concentration of glucose, sodium and urea. This, in turn, is a consequence of osmotic diuresis which is non balanced by elevation in the volume of water intake. Factors facilitating development of the coma include: nontreated diabetes, infirmity, inadequate care, diuretics, stroke, hyperthermia. Hypoglycaemia in the elderly is a very serious problem. It can cause arrhythmia, a rise in the blood pressure, unconsciousness, falls and injuries. The most often reason of hypoglycaemia in the elderly are: long-acting derivatives of sulphonylurea, treatment with insulin and irregular meals. The major aims of treatment of diabetes in the elderly are: reduction of hyperglycaemia, reduction in the development of complications and minimizing of the risk of hypoglycaemia. An elderly patient with diabetes should have each year a check-up which would include examination of the eyes, kidneys, feet. The elderly patient with diabetes is often crippled, indolent and lives often alone. Therefore, such a patient should be taken care of

    Okara, a food by-product from the production of tofu and soy milk, is rich in three beneficial components: insoluble dietary fiber, β-conglycinin, and isoflavones. Although isoflavones and β-conglycinin have recently been shown to improve glucose tolerance, the effects of okara have not yet been elucidated. Therefore, we herein investigated the effects of okara on glucose tolerance in Goto-Kakizaki (GK) rats, a representative animal model of Japanese type 2 diabetes. Male GK rats were fed a 10% lard diet with or without 5% dry okara powder for 2 weeks and an oral glucose tolerance test was performed. Rats were then fed each diet for another week and sacrificed. The expression of genes that are the master regulators of glucose metabolism in adipose tissue was subsequently examined. No significant differences were observed in body weight gain or food intake between the two groups of GK rats. In the oral glucose tolerance test, increases in plasma glucose levels were suppressed by the okara diet. The mRNA expression levels of PPARγ, adiponectin, and GLUT4, which up-regulate the effects of insulin, were increased in epididymal adipose tissue by the okara diet. These results suggest that okara provides a useful means for treating type 2 diabetes. PMID:27257347

    Diabetic retinopathy (DR) is a common complication of diabetes mellitus and is a major cause of vision loss in middle-aged and elderly people. One-third of people with diabetes have DR. Severe stages of DR include proliferative DR, caused by the abnormal growth of new retinal blood vessels, and diabetic macular oedema, in which there is exudation and oedema in the central part of the retina. DR is strongly associated with a prolonged duration of diabetes, hyperglycaemia and hypertension. It is traditionally regarded as a microvascular disease, but retinal neurodegeneration is also involved. Complex interrelated pathophysiological mechanisms triggered by hyperglycaemia underlie the development of DR. These mechanisms include genetic and epigenetic factors, increased production of free radicals, advanced glycosylation end products, inflammatory factors and vascular endothelial growth factor (VEGF). Optimal control of blood glucose and blood pressure in individuals with diabetes remains the cornerstone for preventing the development and arresting the progression of DR. Anti-VEGF therapy is currently indicated for diabetic macular oedema associated with vision loss, whereas laser photocoagulation prevents severe vision loss in eyes with proliferative DR. These measures, together with increasing public awareness and access to regular screening for DR with retinal photography, and the development of new treatments to address early disease stages, will lead to better outcomes and prevent blindness for patients with DR.

    Invasion of the central nervous system (CNS) by African trypanosomes represents a critical step in the development of human African trypanosomiasis. In both clinical cases and experimental mouse infections it has been demonstrated that predisposition to CNS invasion is associated with a type 1 systemic inflammatory response. Using the Trypanosoma brucei brucei GVR35 experimental infection model, we demonstrate that systemic delivery of the counter-inflammatory cytokine IL-10 lowers plasma IFN-γ and TNF-α concentrations, CNS parasitosis and ameliorates neuro-inflammatory pathology and clinical symptoms of disease. The results provide evidence that CNS invasion may be susceptible to immunological attenuation.

    2009-09-01

    Full Text Available Abstract Diabetic nephropathy is the leading cause of chronic renal disease and a major cause of cardiovascular mortality. Diabetic nephropathy has been categorized into stages: microalbuminuria and macroalbuminuria. The cut-off values of micro- and macroalbuminuria are arbitrary and their values have been questioned. Subjects in the upper-normal range of albuminuria seem to be at high risk of progression to micro- or macroalbuminuria and they also had a higher blood pressure than normoalbuminuric subjects in the lower normoalbuminuria range. Diabetic nephropathy screening is made by measuring albumin in spot urine. If abnormal, it should be confirmed in two out three samples collected in a three to six-months interval. Additionally, it is recommended that glomerular filtration rate be routinely estimated for appropriate screening of nephropathy, because some patients present a decreased glomerular filtration rate when urine albumin values are in the normal range. The two main risk factors for diabetic nephropathy are hyperglycemia and arterial hypertension, but the genetic susceptibility in both type 1 and type 2 diabetes is of great importance. Other risk factors are smoking, dyslipidemia, proteinuria, glomerular hyperfiltration and dietary factors. Nephropathy is pathologically characterized in individuals with type 1 diabetes by thickening of glomerular and tubular basal membranes, with progressive mesangial expansion (diffuse or nodular leading to progressive reduction of glomerular filtration surface. Concurrent interstitial morphological alterations and hyalinization of afferent and efferent glomerular arterioles also occur. Podocytes abnormalities also appear to be involved in the glomerulosclerosis process. In patients with type 2 diabetes, renal lesions are heterogeneous and more complex than in individuals with type 1 diabetes. Treatment of diabetic nephropathy is based on a multiple risk factor approach, and the goal is retarding the

    Diabetic muscle infarction is a rare, often unrecognized complication seen in patients with poorly controlled Diabetes Mellitus. The diagnosis is often missed and leads to unnecessary invasive investigations and inappropriate treatment. The patients usually present with unilateral thigh pain and swelling. MRI typically demonstrates diffuse swelling and increased T2 signal intensity within the affected muscles. The condition is self-limiting and is treated conservatively with bed rest and analgesics. Recurrences have been reported in the same or contralateral limb. We report a case of diabetic muscle infarction with spontaneous resolution of symptoms and imaging abnormality with recurrence on the contralateral side.

    Diabetes insipidus is an uncommon pathology; its incidence varies from two to six cases in 100,000 pregnancies. It has multiple etiologies and it is classified in central and neurogenic. Patients with diabetes insipidus generally show intense thirst, polyuria, neurologic symptoms and hypernatremia. It does not seem to alter the patient's fertility. Diabetes insipidus is usually associated with pre-eclampsia, HELLP syndrome, and fatty liver disease of pregnancy. This is a report of a case seen at the Hospital General de Cholula, in Puebla, Mexico. A 19 year-old female, with 37.2 weeks of pregnancy, had a history of Langerhans cell histiocytosis since she was four years. Patient was treated with intranasal desmopressin until 2005. She went to an obstetric evaluation; laboratory and cabinet studies were obtained. A healthy 1900 g female was obtained through vaginal delivery, with a 7/9 Apgar score. We should be familiarized with this uncommon pathology because of its association with several obstetric emergencies.

    Objective: To evaluate tear film stability and tear secretion in patients with diabetes after phacoemulsification. Methods: Twenty-five diabetic cataract patients and 20 age-matched non-diabetic cataract patients as control underwent phacoemulsification. Tear film break-up time (TFBUT), Schirmer I test (SIT), corneal fluorescein staining, and dry eye symptoms were measured pre- and postoperatively. Results: Diabetics had a decreased preoperative TFBUT and SIT. TFBUT was reduced on Day 1 and recovered on Day 180 postoperatively in both groups. SIT was increased after phacoemulsification, but returned to preoperative levels by Day 180 in non-diabetics, whereas it was lower than preoperative level in diabetics. Positive corneal fluorescein staining was elevated in both groups, and returned to preoperative levels only in controls. Dry eye symptoms were similar to fluorescein staining in both groups. Conclusion: Tear secretion was reduced in diabetic cataract patients after phacoemulsification, which worsened dry eye symptoms and predisposed those patients to ocular damage.

    2008-01-01

    Full Text Available Background: Lumbosacral radiculoplexus neuropathy (LRPN originally described in diabetic patients is a distinct clinical condition characterized by debilitating pain, weakness and atrophy most commonly affecting the proximal thigh muscles asymmetrically. The syndrome is usually monophasic and preceded by significant weight loss (at least more than 10 lbs. Though a self-limited condition, recovery is gradual with some residual weakness. Recent advances and research has provided new insights in the pathogenesis and thereby management of this syndrome. In this paper, we review the clinical and diagnostic features as well as discuss recent insights and treatment strategies along with our experience in the management of patients with diabetic and non-diabetic LRPN. Materials and Methods: Literature in English published between 1953 and 2008 was searched in the MEDLINE and Pubmed database, maintained by the US National library of medicine and National institutes of health, using key words of diabetic amyotrophy, lumbosacral radiculoplexus neuropathy, diabetic proximal neuropathy, diabetic radiculopathy and diabetic lumbosacral plexopathy. In addition, literature reported in various textbooks on peripheral neuropathy was reviewed as well. Observation: The diagnosis relies mostly on clinical suspicion and characteristic electromyographic findings. The exact pathogenesis of the illness remains unknown, but there seems to be a component of immune-mediated inflammatory microvasculitis which causes secondary ischemia of the lumbosacral plexus. This has prompted a trial of immunosuppressive agents (like steroids with an attempt to alter the course of the illness. A few reports have noted that immunosuppression when instituted early in the course of the illness (within three months of symptom onset may hasten the recovery and improve symptoms. Conclusion: Though the exact mechanism of LRPN in diabetic and non-diabetic patients remains unknown, new evidence

    Type 2 diabetes has become a pandemic disease over the past 50 years. Its incidence increases the most rapidly in the senior population, i.e. among people older than 65. In a number of countries 1/4 of the people with diabetes are now older than 65 years. Geriatrics now examines numerous differences regarding the senior patients, which often lead to somewhat different therapeutic procedures as compared to the treatment of other adult patients. This paper aims to show some different aspects of the treatment of an elderly patient with diabetes. The intensity of diabetes treatment in the elderly is mainly defined by the incidence of symptoms caused by diabetic decompensation which negatively affect quality of life and are likely to increase mortality. The treatment goals expressed by HbA1c, fasting and post-prandial glycemia, should be set individually based on age, initial HbA1c, present comorbidities and the level of frailty of an elderly patient. An effort to reduce weight regarding people at an older age is probably inappropriate and maybe even harmful, while physical activity reduces mortality and slows muscle catabolism at every age. Ideal is normal walking for 20-30 minutes a day. Except for "very fit elders" without renal insufficiency, the sulfonylurea treatment is unsuitable and perhaps even harmful. It significantly increases the incidence of different types of hypoglycemia and very likely overall mortality as well. The basis of diabetes treatment for the elderly is the effort to perform any regular exercise. In regard to medication treatment it is recommended to choose metformin or gliptin following the rule "start low, go slow", i.e. start with low medication doses and increase them at a slow pace. The main goal of the treatment is to maintain the good quality of life as long as possible, without symptoms associated with hyperglycemia with minimizing the risk of hypoglycemia development.

    Full Text Available The overexpression of vascular endothelial growth factor (VEGF is known to be involved in the pathogenesis of diabetic nephropathy. In this study, the protective effects of taurine on diabetic nephropathy along with its underlying mechanism were investigated. Experimental animals were divided into three groups: LETO rats as normal group (n=10, OLETF rats as diabetic control group (n=10, and OLETF rats treated with taurine group (n=10. We treated taurine (200 mg/kg/day for 20 weeks and treated high glucose (HG, 30 mM with or without taurine (30 mM in mouse cultured podocyte. After taurine treatment, blood glucose level was decreased and insulin secretion was increased. Taurine significantly reduced albuminuria and ACR. Also it decreased glomerular volume, GBM thickness and increased open slit pore density through decreased VEGF and increased nephrin mRNA expressions in renal cortex. The antioxidant effects of taurine were confirmed by the reduction of urine MDA in taurine treated diabetic group. Also reactive oxygen species (ROS levels were decreased in HG condition with taurine treated podocytes compared to without taurine. These results indicate that taurine lowers glucose level via increased insulin secretion and ameliorates the progression of diabetic nephropathy through antifibrotic and antioxidant effects in type 2 diabetes rat model.

    Full Text Available This study was designed to investigate the anti-diabetic hypoglycaemic properties of an ethanolic extract of the root of Celosia argentea which is widely used in India as a traditional treatment for diabetes mellitus. An ethanolic extract of C. argentea root was found to lower blood glucose in basal conditions and after a heavy glucose load in normal rats. Maximum reduction in serum glucose was observed after 90 minutes at a dose of 500 mg/kg (63.28% of body weight, but petroleum ether and chloroform extracts (8.52% and 9.81%, respectively did not reduce the serum glucose. Ethanolic extract of C. argentea was also found to reduce the increase of blood sugar found in streptozotocin-induced diabetic rats (73.43% at 250 mg/kg and 80.20% at 500 mg/kg body weight on 15th day. Chronic administration of the extract significantly reduced the blood sugar in streptozotocin-induced diabetic rats for several days (15 days. The ethanolic extract was also found to reduce the increased levels of cholesterol, triglycerides and urea. The extract also restored the decreased level of proteins and liver glycogen in streptozotocin-induced diabetic animals and inhibited the body weight reduction induced by streptozotocin administration. These results indicate that C. argentea root extracts are able to ameliorate biochemical damages induced by streptozotocin in diabetic rats.

    During the past several decades, the number of both business and tourist travels has greatly increased. Among them are persons suffering from chronic diseases, including diabetics for whom travels pose the additional health-hazard. Irrespective of better education, self-control and constantly improving quality of specialistic equipment available, diabetics still are the group of patients requiring particular attention. In the case of travelling diabetics, problems may occur concerning the transport and storage of insulin, as well as control of glycaemia, all caused by irregularity of meals, variable diet, physical activity, stress, kinetosis (sea voyages), and the change of time zones. The travel may as well evoke ailments caused by the change of climate and concomitant diseases such as traveller's diarrhoea, malaria, etc. Apart from avoiding glycaemia fluctuations, important for retaining health of diabetics is the prevention of other diseases and carrying the necessary drugs.

  18. Driving with diabetes: precaution, not prohibition, is the proper approach.

    Safety issues posed by driving with diabetes are primarily related to severe hypoglycemia, yet some public authorities rely on categorical restrictions on drivers with diabetes. This approach is misguided. Regulation of all drivers with diabetes, or all drivers using insulin, ignores the diversity of people with diabetes and fails to focus on the subpopulation posing the greatest risk. Advances in diabetes care technology and understanding of safety consequences of diabetes have expanded techniques available to limit risks of driving with diabetes. New means of insulin administration and blood glucose monitoring offer greater ease of anticipating and preventing hypoglycemia, and thus, limit driving risk for persons with diabetes. So too do less sophisticated steps taken by people with diabetes and the health care professionals they consult. These include adoption and endorsement of safety-sensitive behaviors, such as testing before a drive and periodic testing on longer trips. Overall, and in most individual cases, driving risks for persons with diabetes are less than those routinely tolerated by our society. Examples include freedom to drive in dangerous conditions and lax regulation of drivers in age and medical cohorts with elevated overall rates of driving mishaps. Data linking specific diabetes symptoms or features with driving risk are quite uncertain. Hence, there is much to recommend: a focus on technological advances, human precautions, and identifying individuals with diabetes with a specific history of driving difficulty. By contrast, available evidence does not support unfocused regulation of all or most drivers with diabetes.

    ObjectiveTo study the changes in serum cortisol levels in adolescents with type 1 diabetes (T1DM) and elevated depressive symptoms.MethodsTwenty-eight adolescents with T1DM and 31 healthy peers were assessed for depressive symptoms using a depression self-rating scale developed by the Epidemiological Survey Center. Selected subjects were classified into four groups: T1DM with elevated depressive symptoms group (n=15), T1DM without elevated depressive symptoms group (n=13), elevated depressive symptoms without T1DM group (n=15), and normal control group (n=16). Fasting blood samples were collected in the morning, and the levels of serum cortisol were compared among the four groups. The correlations of serum levels of cortisol and glycosylated hemoglobin A1c (HbA1c) with the score of depression self-rating scale were evaluated by Pearson correlation analysis.ResultsThe fasting serum cortisol levels in the 28 T1DM patients were significantly higher than in the 31 healthy peers (P<0.01). The fasting cortisol levels in the T1DM with elevated depressive symptoms group were signiifcantly higher compared with those in the elevated depressive symptoms without T1DM group and normal control group (P<0.01). In adolescents with T1DM, serum HbA1c level was positively correlated with the score of depression self-rating scale (r=0.481,P=0.010). ConclusionsThe fasting serum cortisol levels in adolescents with T1DM and elevated depressive symptoms are signiifcantly increased, suggesting that the patients with comorbidity of T1DM and depression develop dysfunction of the corticotropin-releasing hormone-adrenocorticotropic hormone-cortisol axis. The elevated depressive symptoms may be associated with a poor control of glucose metabolism.%目的:了解青少年1型糖尿病(T1DM)伴阳性抑郁症状患者的血清皮质醇变化特点。方法对28例青少年T1DM患者和31例健康同龄人采用流调中心用抑郁自评量表筛查阳性抑郁症状者,分为T1DM伴
