Aims: The objective of this study was to explore the effects of epigallocatechin-3-gallate (EGCG) on type 2 diabetes mellitus (T2DM). Main methods: Male Sprague–Dawley rats were allocated into six groups. The control group received a conventional diet. The diabetic group received a high-sucrose high-fat (HSHF) diet for 4 weeks and then was fasted and injected with streptozotocin (STZ); subsequently, the rats received a HSHF diet for another 4 weeks to develop diabetes. The four treatment groups were diabetic rats that received intragastric metformin (500 mg/kg/day) or EGCG (25, 50, and 100 mg/kg/day) for 10 weeks. All groups except the control group received a HSHF diet throughout the experiment. Several biochemical parameters such as fasting blood glucose (FBG), postprandial blood glucose (PBG), liver glycogen, muscle glycogen, fasting serum insulin (FSI), homeostasis model of insulin resistance (HOMA-IR), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), free fatty acids (FFA), superoxide dismutase (SOD), and malondialdehyde (MDA) were measured to assess the effects of EGCG on glycemic control, insulin resistance, lipid profile, and oxidative stress. Furthermore, oxidative stress in pancreatic islet β cells was detected by dihydroethidium staining. Key findings: A HSHF diet and STZ injection induced T2DM, as indicated by changed blood glucose and body weight, which was accompanied by insulin resistance, an altered lipid profile, and oxidative stress. Interestingly, EGCG treatment dose-dependently recovered these indexes. Significance: EGCG successfully ameliorated glycemic control and insulin sensitivity while reducing the lipid profile and oxidative stress in a T2DM rat model.

Background: The ethanomedicinal importance of Moringa concanensis Nimmo plant is reflected in Ayurvedic and traditional system of medicine. It brings out its importance as diverse plant in Ayurvedic preparation and diabetes management. Aims of study: The research was centred to bring out the Hyperglycemiccapabilities of Moringa concanensis Nimmo leaves Ethanolic extract (PE) on Alloxan monohydrate (AXM) induceddiabetic rat model. Materials and Methods: Wistar rats were made diabetic by AXM and treated with PE (200 mg/kg body weight) and glibenclamide as a standard drug. All Essential parameters like Fasting blood glucose (FBS), Post prandial blood glucose (PPBS), AST, ALT, ALP, ACP, LDH and oxidative stress markers were measured. Also to see β-cells structures histology of pancreas was also done. Results: The non toxicity of PE dose was confirmed by acute toxicity study and also this study models helped to know about the anti-hyperglycemic effects of PE by decreasing FBS and PPBS levels in the diabetic rats. It also enhances oxidative stress by decreasing MDA levels and elevating the GSH and SOD. The histopathological analysis helped us to know about structure decay of β-cells of pancreas tissue of diabetic rats. PEpotential was confirmed by serum enzymes AST, ALT, ALP, ACP and LDH as it showed significant decrease in diabetic rats. Conclusion: It was confirmed from the data that PE is efficient in governance of diabetes and its control, so there is a need to work at molecular level to bring out all its potential for the benefit of the society.

The black cumin (Nigella sativa) “NS” or the black seeds have many pharmacological activities such as antioxidant, anticarcinogenic, antihypertensive, and antidiabetic properties. In this work, streptozotocin-induced diabetic rats fed with a high-fat diet were treated daily with NS oil (NSO) in order to study the effect on the blood glucose, lipid profile, oxidative stress parameters, and the gene expression of some insulin receptor-induced signaling molecules. This treatment was combined also with some drugs (metformin and glimepiride) and the insulin receptor inhibitor I-OMe-AG538. The administration of NSO significantly induced the gene expression of insulin receptor compared to rats that did not receive NSO. Also, it upregulated the expression of insulin-like growth factor-1 and phosphoinositide-3 kinase, whereas the expression of ADAM-17 was downregulated. The expression of ADAM-17 is corroborated by the analysis of TIMP-3 content. In addition, the NSO significantly reduced blood glucose level, components of the lipid profile, oxidative stress parameters, serum insulin/insulin receptor ratio, and the tumor necrosis factor-α, confirming that NSO has an antidiabetic activity. Thus, the daily NSO treatment in our rat model indicates that NSO has a potential in the management of diabetes as well as improvement of insulin-induced signaling.
