The objective of the present study was to evaluateα-glucosidase inhibitory and antidiabetic effects of Nopal water extract (NPWE) and Nopal dry power (NADP) in low-dose streptozotocin- (STZ-) induced diabetic rats fed a high-fat diet (HFD). The type 2 diabetic rat model was induced by HFD and low-dose STZ. The rats were divided into four groups as follows: (1) nondiabetic rats fed a regular diet (RD-Control); (2) low-dose STZ-induced diabetic rats fed HFD (HF-STZ-Control); (3) low-dose STZ-induced diabetic rats fed HFD and supplemented with NPWE (100 mg/kg body weight, HF-STZ-NPWE); and (4) low-dose STZ-induced diabetic rats fed HFD and supplemented with comparison medication (rosiglitazone, 10 mg/kg, body weight, HF-STZ-Rosiglitazone). In results, NPWE and NADP had IC50values of 67.33 and 86.68 μg/mL, both of which exhibit inhibitory activities but lower than that of acarbose (38.05 μg/mL) while NPWE group significantly decreased blood glucose levels compared to control and NPDP group on glucose tolerance in the high-fat diet fed rats model (P<0.05). Also, the blood glucose levels of HR-STZ-NPWE group were significantly lower (P<0.05) than HR-STZ-Control group on low-dose STZ-induced diabetic rats fed HFD. Based on these findings, we suggested that NPWE could be considered for the prevention and/or treatment of blood glucose and a potential use as a dietary supplement.

Abstract BackgroundOptimization of experimental conditions in streptozotocin induced diabetic model in Sprague Dawley (SD) rats to evaluate the stability of the model.MethodsMale and female SD rats were randomly divided into control group, STZ 45 group (STZ: 45 mg / kg), STZ 65 group (STZ: 65 mg / kg), STZ 85 group (STZ: 85 mg / kg), high fat diet with STZ 45 group (STZ: 45 mg / kg), high fat diet with STZ 65 group (STZ: 65 mg / kg), high fat diet with STZ 85 group (STZ: 85 mg / kg). N = 6 in each group. The changes of body weight and blood glucose were observed dynamically.ResultsThere was no significant difference in blood glucose or body weight between the STZ 45 group and the control group in both male and female rats, whether or not they were on a high-fat diet. However, there were significant differences in blood glucose between the high-dose STZ group and the control group in both male and female rats, regardless of whether the rats were on a high-fat diet or not (P < 0.05 or P < 0.01). Compared with the control group, there were significant differences in blood glucose levels (P < 0.05 or P < 0.01) and higher blood glucose levels in the male rats fed with the normal diet than that in those fed with the high-fat diet.ConclusionsIn this study, male rats fed with ordinary feed and injected STZ dose of 65 mg / kg were the most stable and ideal diabetic rat.

Eriobotrya japonica locally called as loquat in Kashmir has been studied in various parts of the world but little work has been reported on Kashmiri loquat. The chemical nature of fruits and vegetables offers a great diversity of biological properties and plays an important role in the field of pharmacology. There is a quest for newer drugs with few adverse effects and this poses a challenge for the development of new drugs. The study was undertaken to study the activities of ethanolic extract of Eriobotrya japonica fruits in streptozotocin induced diabetic rats. The phytochemical screening of the plant was also done. The animals were divided into five groups. Normal Control group received only the vehicle. Toxic group included those animals in which diabetes was induced by streptozotocin. The 3rd group was those animals which received streptozotocin and standard antidiabetic drug-glibenclamide. 4th group included those diabetic animals which received 50 mg/kg b.w dose of fruits of Eriobotrya japonica. 5th group animals included those diabetic animals which received 100 mg/kg b.w of the plant extract. The biochemical parameters that were evaluated were blood glucose levels and lipid profile tests. The body weight was also checked. Histopathology of pancreas was also done. The results showed significant decrease in blood glucose levels, lipid profile tests in animals treated with different doses of the plant extracts. Histopathology of pancreas also showed positive results.

Background: Medicinal plants are now becoming indispensable in the treatment and management of many ailments. The unaffordability, unavailability and adverse effects of conventional therapy in the treatment and management of many diseases have geared keen interest in the use of herbal medicine. This work was carried out to investigate the prophylactic effect of the ethanol extract of Azadirachta indica leaf in streptozotocin-induced diabetic rats.   Methods: A total of one hundred (100) rats were randomized into four (4) groups (n=25) and used for the study. Each group of 25 rats was sub-divided into five (5) groups (n=5). The sub-groups comprise: Group A-normal control that was not treated, group B-100 mg/kg body weight of metformin and groups C to E - graded doses (100 mg/kg, 200 mg/kg and 400 mg/kg body weight) of the ethanol leaf extracts of A. indica leaves. The standard drug and the extracts were consecutively administered to groups B-E for 7, 14, 21 and 28 days before the induction of diabetes. Diabetes was induced intraperitoneally using 50 mg/kg bodyweight of streptozotocin. Results: The groups that were administered 100, 200 and 400 mg/kg bw of ethanol extract of A. indica showed a significant (p<0.05) increase in their weight after 21 and 28 days of pre-treatment compared with the control group that was not treated. The graded doses of the extract also have a remarkable effect in the fasting blood glucose levels which was made visible by the significant (p<0.05) reduction recorded in the fasting blood glucose levels compared with the control group that was not pre-treated and the group pre-treated with metformin. Conclusion: The results obtained in this research suggest that ethanol extract of A. indica has the potential to protect against diabetes by delaying its onset. However, the longer the period of pre-treatment, the better the condition of the animals pre-treated as well as the protection as can be seen from the results of the weight and fasting blood glucose levels.

Gpr119 Agonist

The search for new drugs for the treatment of type 2 diabetes mellitus (T2DM) and obesity remains an urgent problem. Drugs with influence on incretin system are widely used in the treatment of T2DM and obesity, since in addition to the hypoglycemic action of their inherent hypophagic effects. With the discovery of GPR119 receptor, there is the opportunity to pharmacological stimulation of endogenous secretion of incretins. Compound ZB-16 is active GPR119 agonist with IC50=7 nM. Its activation leads to increased secretion of the major incretins (GLP-1 and GIP), which are able to influence glucose metabolism and feeding behavior.Aims — to study the effect of GPR 119 receptor agonist compounds ZB-16 on blood glucose, body weight and food intake in rats with obesity.Material and methods.Male rats with initial weight 390—400 g were fed with high-carbohydrate and high-fat diet. During the next four weeks the animals orally received ZB-16 (1 mg/kg) and metformin (400 mg/kg) and then we assessed the level of water and food consumption, blood glucose levels, and performed oral glucose tolerance test (OGTT).Results.Compound ZB-16 and metformin reduced fasting blood glucose levels and weight of experimental animals, while the control rats gained weight. GPR119 agonist is more pronounced than metformin reduced the area under the curve «glucose of concentration—time» during the OGTT.Conclusions.Novel GPR119 agonist — ZB-16 is comparable to metformin in hypoglycemic and anorexigenic effect in animals with obesity caused high-carbohydrate and high-fat diet.

T2DM has increase in global-morbidity and mortality. Oxidative stress and adiponectin-levels are important for insulin-resistance and pancreatic-b-cell-dysfunction in T2DM. Okra fruit is rich of quercetin and phytosterol which have positive-effect for T2DM. Research aimed was to study the effect of okra-flour to adiponectin-levels and total-antioxidant-capacity (TAC) in T2DM. Thirty Wistar-rats were divided randomly in five groups. K1 and (X1, X2 and X3)-treated-groups were in T2DM-condition-induced by high-fat-diet-(HFD)-Streptozotochin-(STZ)-nicotinamid-(NA). Healthy-controls-(K2)-group was also used. Okra-flour was given orally for 28 days at doses of 0.1; 0.2 and 0.3 g/Kg-body-weight/d to X1, X2 and X3-groups, respectively. Statistical program was used to analyse the different between pre-post-intervention, and between groups. Correlations between variables were also analysed. The serum-adiponectin and TAC-levels were measured by ELISA and ABTS-methods, respectively. By comparing pre and post-intervention, adiponectin levels of all-intervention-(X1, X2, X3)-group were  increase (p = 0.027 for X1 and X2; p = 0.028 for X3), while in the same period the decrease were found in group K1 (p = 0.026) and K2 (p = 0.028). Increase-TAC-levels pre-post-intervention was observed in group all-intervention-groups (p = 0.027), while no change in K1 (p = 0.66) and the decrease in group K2 (p = 0.039). Reduce-fasting-blood-glucose-levels pre-post-intervention were shown in the all-intervention-groups (p = 0.028), while for the K1 groups was increase (p = 0.028). There were significant differences between the five-groups on fasting-blood-glucose-levels, adiponectin and TAC-levels, and X3-group showed the highest adiponectin and TAC-levels. Very-strong-correlations were found between glucose-adiponectin-TAC-levels-post-intervention. Okra-flour make better glucose-adiponectin and TAC-levels in T2DM-conditions. Okra dose of 0.30 g/Kg-body-weight/day is the best in increasing adiponectin and TAC-levels.

Objective: The aim of the study was to evaluate the antidiabetic potential of Perillyl alcohol (POH) in high-fat diet (HFD) and low-dose streptozotocin (STZ)-induced diabetic Wistar rats. Methods: In experimental rats fed with HFD for 4 weeks, diabetes was induced by single intraperitoneal injection of STZ (35 mg/kg body weight [BW]). Three days after STZ induction, the hyperglycemic rats were treated with POH orally at the doses of 50 and 100 mg/kg BW daily for 30 days. Glibenclamide (6 mg/kg BW) was used as reference drug. Blood glucose level, BW, fluid intake, and food intake such as parameters were analyzed throughout the experiment period. Serum and plasma biochemical parameters were also estimated. Assay on insulin resistance was also done. Histological study of the pancreas and liver was also performed. Results: POH orally at the doses of 50 and 100 mg/kg BW for 30 days significantly (p<0.05) and dose-dependently reduced and normalized blood glucose levels as compared to that of HFD+STZ control group. Serum and plasma parameters were significantly (p<0.05) restored toward the normal levels in POH-treated rats as compared to HFD-STZ control animals. Histological study of liver and pancreas also shows the prominent regeneration in POH and glibenclamide treated rats. Conclusion: The present study concludes that POH demonstrated promising antidiabetic action in HFD STZ-induced diabetic rats.

Objective: India is the “diabetes capital of the world” with 62.4 million Indians having type 2 diabetes in 2011. A major risk factor for insulin resistance is obesity, which is generally caused by regular physical inactivity and high-fat diet (HFD). Obesity and diabetes are closely related to each other as about 80% of diabetics are obese. Obesity is a common finding in type 2 diabetes. The objective of the study was to investigate the antidiabetic effects of [10]-gingerol in streptozotocin (STZ)- and HFD-induced diabetic rats. Methods: Wistar rats were used for the study. Animals were divided into six groups. The six groups in this study were, Group I (normal control), Group II (diabetic control), Group III (glibenclamide at 5 mg/kg p.o.), Group IV (orlistat at 60 mg/kg p.o.), Group V ([10]-gingerol at 15 mg/kg p.o.), and Group VI [10]-gingerol (30 mg/kg p.o.), respectively. The antidiabetic activity was assessed using blood glucose level, body weight, and various biochemical parameters such as serum total cholesterol (TC) level, triglyceride (TG) level, high-density lipoproteins (HDLs), total protein (TP), serum alanine transaminase, and aspartate aminotransferase (serum glutamic-oxaloacetic transaminase), respectively. Results: [10]-gingerol exhibited an antidiabetic effect by significantly decreased the level of blood glucose, body weight, TC, TG, TP, and increase HDL. The results of the study demonstrated that the treatment with [10]-gingerol significantly (p<0.05) and dose dependently prevented STZ- and HFD-induced diabetic rats. Conclusions: The findings of the study suggest that [10]-gingerol possesses potential antidiabetic activity as it lowers serum glucose level.

Abstract. Objective: This study aimed to evaluate the effect of maternal consumption of flaxseed flour and oil on serum concentrations of glucose, insulin, and thyroid hormones of the adult female offspring of diabetic rats. Methods: Wistar rats were induced to diabetes by a high-fat diet (60%) and streptozotocin (35 mg/kg). Rats were mated and once pregnancy was confirmed, were divided into the following groups: Control Group (CG): casein-based diet; High-fat Group (HG): high-fat diet (49%); High-fat Flaxseed Group (HFG): high-fat diet supplemented with 25% flaxseed flour; High-fat Flaxseed Oil group (HOG): high-fat diet, where soya oil was replaced with flaxseed oil. After weaning, female pups (n = 6) from each group were separated, received a commercial rat diet and were sacrificed after 180 days. Serum insulin concentrations were determined by ELISA, the levels of triiodothyronine (T3), thyroxine (T4) and thyroid-stimulating hormone (TSH) were determined by chemiluminescence. Results: There was a significant reduction in body weight at weaning in HG (−31%), HFG (−33%) and HOG (44%) compared to CG (p = 0.002), which became similar by the end of 180 days. Blood glucose levels were reduced in HFG (−10%, p = 0.044) when compared to CG, and there was no significant difference between groups in relation to insulin, T3, T4, and TSH after 180 days. Conclusions: Maternal severe hyperglycemia during pregnancy and lactation resulted in a microsomal offspring. Maternal consumption of flaxseed reduces blood glucose levels in adult offspring without significant effects on insulin levels and thyroid hormones.
