Type 2 Diabetic

Type 2 diabetes is one of the most important diseases worldwide. It affects several organ systems including the liver and lipid metabolism. Many herbal formulations have shown anti-diabetic potential, however, their safety and efficacy remain a debate in the medical community. Aim: This study evaluates the therapeutic effects of the anti-diabetic polyherbal drug diawell in combination with metformin on liver enzyme and lipid profile in type 2 diabetic rats. Methodology: A total of 35 male Wistar albino rats weighing between 120-220 g were used for this study. The rats were placed on high fat diet, and diabetes was induced by a single intraperitoneal injection of freshly prepared streptozotocin (STZ) (45 mg/kg body wt). Fasting plasma glucose (FPG) was determined using the glucose oxidase method. Total Cholesterol (TC), Triglyceride (TG) and High density lipoprotein cholesterol (HDL-C) were determined using enzymatic methods. Low density lipoprotein cholesterol (LDL-C) was calculated using the Friedewald equation. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were determined using Reitman-Frankel method, while alkaline phosphatase (ALP) was determined using the colorimetric phenolphthalein method. Liver sections were stained using haematoxylin and eosin (H&E) staining technique, and phytochemical analysis was also done on the herbal tablet. Results: The results show no significant differences in mean TC levels in all groups. TG level was significantly higher in the diabetic control when compared to the negative control. There were no significant differences in TG levels in the metformin group, and diawell group when compared to the diabetic control. TG levels in the combination group (metformin + diawell) was significantly lower versus the diabetic control, and showed no significant difference compared to the negative control. HDL-C was significantly higher in the negative control when compared to the diabetic control and the treatment groups. There were no significant differences in HDL-C levels in all the treatment groups, when compared to the diabetic control. LDL-C levels were significantly lower in the negative control compared to the diabetic control and treatment groups. There were no significant differences in LDL-C levels in all the treatment groups, when compared to the diabetic control. The diabetic control had significantly higher ALT, AST and ALP levels compared to the negative control and treatment groups. All the treatment groups showed no significant differences in ALT and AST levels compared to the negative control. Liver sections of the negative control showed normal histoarchitecture. The diabetic control showed inflammation and fatty deposition. The treatment groups showed a nearly normal histoarchitecture, with fatty deposits. Conclusion: High fat diet in combination with 45 mg/kg of STZ produced significant diabetes in the Wistar rats with dyslipidaemia and elevated liver enzyme levels. Metformin and the polyherbal tablet diawell had no impact on the lipid levels as it did not correct the dyslipidaema, however, the treatments showed hepatoprotective potentials and restored liver enzyme levels to normal. Lipid lowering drugs should be included in the management of type 2 diabetes, and there should be proper evaluation of anti-diabetic herbal products.

Type 2 Diabetic

Coptis chinensis (CC) is widely used to treat diabetes in traditional Chinese medicine due to its significant hypoglycemic and hypolipidemic effects. It was reported that CC powders are more effective than CC decoctions. In this study, a rat model of type 2 diabetes was established and treated with supercritical-extracted CC and gastric juice extracted CC, respectively. Body weight, fasting plasma insulin, insulin resistance index, and lipid profiles were measured along with oral glucose tolerance tests (OGTTs). In addition, the levels of plasma proteins were compared between type 2 diabetic rats and CC-treated rats using an iTRAQ-based quantitative proteomic analysis. The results showed that the plasma levels of triglyceride (TC), total cholesterol (TG), and low-density lipoprotein (LDL) in rats of both CC-treated groups were significantly decreased. In addition, the proteomic analysis identified 929 proteins, while 15 proteins were selected from these 929 proteins based on their expression levels and bioinformatic results. Among these 15 proteins, 9 proteins (IGF-1, Igfbp4, Igfbp-6, Igfals, C2, C4, Cfi, Prdx-2, and Prdx-3) were upregulated in the two CC-treated groups, while 6 proteins (Pla2g7, Pcyox1, ApoC-1, ApoC-3, ApoB-100, and ApoE) were downregulated. The functions of these proteins are associated with glucose metabolism, insulin action, immunity, inflammation, lipid metabolism, oxidation, and antioxidation. The two differently extracted CC did not show significant differences in terms of their treatment efficacy. This research expanded our understanding on the therapeutic effects and mechanisms of CC in the treatment of type 2 diabetes.
