Background and Aims: SNARE proteins are composed of a combination of SNAP-23, Stx-4, and VAMP-2 isoforms that are significantly expressed in skeletal muscle. These proteins control the transport of GLUT4 to the cell membranes. The modifications in the expression of SNARE proteins can cause Type 2 diabetes. The present study aimed to assess the effect of metformin on the expression of these proteins in rats. Materials and Methods: For the purpose of the study, 40 male Wistar rats were randomly selected. Streptozotocin and Nicotinamide were used for the induction of type 2 diabetes. The animals were assigned to five groups (n=8), including healthy and diabetic groups as control, as well as three experimental groups which were treated with different doses of metformin (100, 150, and 200 mg/kg body weight) for 30 days. The quantitative reverse transcription PCR (RT-qPCR) method was applied to evaluate the expression of SNARE complex proteins.. Results: Based on the results, metformin (100, 150, and 200 mg/kg body weight) decreased serum glucose levels and increased serum insulin levels. This difference in dose of 200 mg/kg body weight was statistically significant (P<0.05). Moreover, all three doses of metformin increased the expression of SNAP- 23, syntaxin-4, and VAMP-2 proteins in skeletal muscle tissue. Metformin at a dose of 200 mg/kg body weight demonstrated the most significant effects (P<0.05). Conclusion: As evidenced by the results of the current study, another anti-diabetic mechanism of metformin is to increase the expression of SNARE proteins, which effectively improves insulin resistance and lowers blood glucose.

Abstract Background Ethnobotany knowledge in a community has shaped local wisdom in utilizing plants to treat diseases, such as the use of Malaka (Phyllanthus emblica) flesh to treat type 2 diabetes. This study presented evidence that the phenolic extract of the Malaka flesh could reduce blood sugar levels in the diabetic induced rats. Methods The phenolic extract of the P. emblica was administrated to the glucose-induced rats of the Wistar strain Rattus norvegicus for 14 days of treatment where the Metformin was used as a positive control. The data generated were analyzed by the two-way ANOVA Software related to the blood glucose level and by SAS Software related to the histopathological studies at a significant 95% confidence. Results The phenolic extract with concentrations of 100 and 200 mg/kg body weight could reduce blood glucose levels in diabetic rats. The post hoc Dunnet test showed that the administration of the extract to the rats with a concentration of 100 mg/kg body weight demonstrated a very significant decrease in blood glucose levels and repaired damaged cells better than administering the extract at a concentration of 200 mg/kg weight body. Conclusion The evidence indicated that the phenolic extract of the Malaka flesh can be utilized as anti type 2 Diabetes mellitus without damaging other organs.

Hypothalamic neuropeptide Y (NPY) may be involved in the hyperphagia that follows food deprivation associated with significant weight loss. However, it is unclear whether NPY is involved in body weight regulation under more physiological circumstances. Consequently, we measured body weight, food intake, arcuate nucleus (ARC) NPY mRNA, serum glucose, and insulin in male Wistar rats after 48 h of food deprivation and various refeeding protocols. Food deprivation produced a twofold increase in NPY mRNA, whereas 3 days of ad libitum refeeding returned body weight and NPY mRNA to control. If hyperphagia was prevented for 5 days during refeeding, then neither body weight nor NPY mRNA normalized. There were strong negative correlations between ARC NPY mRNA and both loss of body weight and serum insulin levels. These data suggest that hypothalamic NPY gene expression plays a role in control of body weight under physiological conditions. The data further suggest that NPY mRNA may be decreased by peripheral insulin levels.

Ecklonia cava (E. cava)is a brown alga that has beneficial effects in models of type 1 and type 2 diabetes. However, the effects ofE. cavaextracts on diet-induced obesity and type 2 diabetes have not been specifically examined. We investigated the effects ofE. cavaon body weight, fat content, and hyperglycemia in high-fat diet- (HFD) induced obese mice and sought the mechanisms involved. C57BL/6 male mice were fed a HFD (60% fat) diet or normal chow. After 3 weeks, the HFD diet group was given extracts (200 mg/kg) ofE. cavaharvested from Jeju (CA) or Gijang (G-CA), Korea or PBS by oral intubation for 8 weeks. Body weights were measured weekly. Blood glucose and glucose tolerance were measured at 7 weeks, and fat pad content and mRNA expression of adipogenic genes and inflammatory cytokines were measured after 8 weeks of treatment. G-CA was effective in reducing body weight gain, body fat, and hyperglycemia and improving glucose tolerance as compared with PBS-HFD mice. The mRNA expression of adipogenic genes was increased, and mRNA expression of inflammatory cytokines and macrophage marker gene was decreased in G-CA-treated obese mice. We suggest that G-CA reduces obesity and glucose levels by anti-inflammatory actions and improvement of lipid metabolism.

Introduction: Diabetes mellitus is characterized by hyperglycemia with impaired metabolism of carbohydrates, fats, and proteins resulting from insufficiency of secretion or action of insulin. The interplay of genes and environmental factors is believed to stress glucose homeostasis. Simple dietary and lifestyle modifications have a role in prevention and slow progression of the disease. The choice and role of sweeteners (sugars) such as ordinary cane sugar, honey, and jaggery have always been a difficult decision for patients with Type 2 diabetes. Aims & Objectives: Evaluation and comparison of the effects of cane sugar, honey, and jaggery on plasma glucose in the sera and body weights of alloxan-induced male Wistar rats with diabetes. Place and duration of study: The study was conducted at the animal house of Services Institute of Medical Sciences Lahore for a duration of 20 months approximately. Material & Methods: In this experimental study 120 male Wistar (albino) rats were randomly allocated into 4 groups of 30 each. After acclimatization, freshly prepared 2% alloxan monohydrate was administered to all the rats via intraperitoneal injection in a single dose of 120mg/kg body weight. Blood sample via tail tipping method was analyzed for fasting serum glucose at 4th post-diabetes induction day. Rodents having ? 200mg/dl serum glucose were regarded as type 2 diabetes models for further study. All animals had access to usual pelleted diet ad libitum. Diabetic controls in group I were fed with equivalent amount of distilled water. Group II, III and IV rats were fed freshly prepared sweetener containing cane sugar, honey and jaggery solutions respectively in a dose of 1g/kg body weight dissolved in 2ml distilled water on pre-scheduled time of the day for 28 days via oral syringe-dosing. Final serum glucose was estimated at 29th day of study by terminal blood sampling and final body weights were recorded. Data analysis was performed using SPSS version 20. Results: Group III (honey fed) rats had least hyperglycemia of 34.53±77.31mg/dL, followed by group II (cane sugar fed) rats (79.31±73.03 mg/dL) then group I diabetic control rats (88.11±92.56mg/dL) and maximal rise in jaggery fed rats with value of 134.50 mg/dL. Significant reduction (p=0.049) in body weight (-40.50g) was noted in group II rats whereas maximum weight gain occurred in group I (127.57 ±72.475), than those of group IV rats (69.13 ± 92.88) followed by II rats (38.42±89.43). Conclusion: The result demonstrates that honey in type 2 diabetes mellitus possess antidiabetic properties via minimum hyperglycemic and weight gaining effects than processed cane sugar. As it was presumed, minimally processed jaggery has not shown significant beneficial effects on serum glucose and body weight. Owing to the advantageous effects on metabolic profile, honey may be regarded as a relatively safer sweetener in diabetics.

Hydrogen sulfide (H2S) is involved in the pathophysiology of type 2 diabetes. Inhibition and stimulation of H2S synthesis has been suggested to be a potential therapeutic approach for type 2 diabetes. The aim of this study was therefore to determine the effects of long-term sodium hydrosulfide (NaSH) administration as a H2S releasing agent on carbohydrate metabolism in type 2 diabetic rats. Type 2 diabetes was established using high fat-low dose streptozotocin. Rats were treated for 9 weeks with intraperitoneal injections of NaSH (0.28, 0.56, 1.6, 2.8, and 5.6 mg/kg). Serum glucose was measured weekly for one month and then at the end of the study. Serum insulin was measured before and after the treatment. At the end of the study, glucose tolerance, pyruvate tolerance and insulin secretion were determined and blood pressure was measured. In diabetic rats NaSH at 1.6–5.6 mg/kg increased serum glucose (11%, 28%, and 51%, respectively) and decreased serum insulin, glucose tolerance, pyruvate tolerance and in vivo insulin secretion. In controls, NaSH only at 5.6 mg/kg increased serum glucose and decreased glucose tolerance, pyruvate tolerance and insulin secretion. Chronic administration of NaSH in particular at high doses impaired carbohydrate metabolism in type 2 diabetic rats.

Euglycemic Diabetic Ketoacidosis

Abstract Background Euglycemic diabetic ketoacidosis is an uncommon but life-threatening complication associated with the use of sodium-glucose cotransporter 2 inhibitors that causes lower than expected blood glucose levels typically seen in diabetic ketoacidosis. Case presentation We present a case of 64-year-old Caucasian male patient previously diagnosed with type 2 diabetes treated with a sodium-glucose cotransporter 2 inhibitor who developed severe ketoacidosis. Serum glucose levels on initial presentation were slightly above normal baseline level. The patient was revealed to have latent autoimmune diabetes in adults. Conclusion This case highlights the importance of prescribing sodium-glucose cotransporter 2 inhibitors to the correct patient population and the significance of accurately differentiating between various types of diabetes.
