Restoration of dysbiosed gut microbiota through probiotic may have profound effect on type 2 diabetes. In the present study, rats were fed high fat diet (HFD) for 3 weeks and injected with low dose streptozotocin to induce type 2 diabetes. Diabetic rats were then fed Lactobacillus rhamnosus NCDC 17 and L. rhamnosus GG with HFD for six weeks. L. rhamnosus NCDC 17 improved oral glucose tolerance test, biochemical parameters (fasting blood glucose, plasma insulin, glycosylated haemoglobin, free fatty acids, triglycerides, total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol), oxidative stress (thiobarbituric acid reactive substance and activities of catalase, superoxide dismutase and glutathione peroxidase in blood and liver), bifidobacteria and lactobacilli in cecum, expression of glucagon like peptide-1 producing genes in cecum, and adiponection in epididymal fat, while decreased propionate proportions (%) in caecum, and expression of tumour necrosis factor-α and interlukin-6 in epididymal fat of diabetic rats as compared to diabetes control group. These findings offered a base for the use of L. rhamnosus NCDC 17 for the improvement and early treatment of type 2 diabetes.

Background Oxidative stress plays a critical role in the pathogenesis and progression of type 2 diabetes and diabetic-associated cardiovascular complications. This study investigated the impact of crocin combined with voluntary exercise on heart oxidative stress indicator in high-fat diet-induced type 2 diabetic rats. Materials and methods Rats were divided into four groups: diabetes, diabetic-crocin, diabetic-voluntary exercise, diabetic-crocin-voluntary exercise. Type 2 diabetes was induced by high-fat diet (4 weeks) and injection of streptozotocin (intraperitoneally, 35 mg/kg). Animals received crocin orally (50 mg/kg); voluntary exercise was performed alone or combined with crocin treatment for 8 weeks. Finally, malondialdehyde (MDA), activity of antioxidant enzymes, superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) were measured spectrophotometrically. Results Treatment of diabetic rats with crocin and exercise significantly decreased the levels of MDA (p < 0.001) and increased the activity of SOD, GPx, and CAT compared with the untreated diabetic group. In addition, combination of exercise and crocin amplified their effect on antioxidant levels in the heart tissue of type 2 diabetic rats. Conclusion We suggest that a combination of crocin with voluntary exercise treatment may cause more beneficial effects in antioxidant defense system of heart tissues than the use of crocin or voluntary exercise alone.

Diabetes mellitus is an epidemic, with a huge disease burden on the patients. This has led to an increase in the use of herbal remedies and combination therapies to reduce this burden. Aim: This study evaluates the biochemical and oxidative changes in type 2 diabetic rats, treated with metformin and the polyherbal drug diawell. 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. Fasting plasma insulin (FPI), total oxidant status (TOS), total antioxidant status (TAS) and superoxide dismutase (SOD) levels were quantitatively determined by a rat-specific sandwich-enzyme linked immunosorbent assay (ELISA) method. Insulin resistance (IR) was determined using the homeostatic model assessment for insulin resistance (HOMA-IR) method. Oxidative stress index (OSI) was determined by the ratio of TOS to TAS. Phytochemical analysis was also done on the herbal tablet. Results: Mean FPG levels were significantly lower (p˂0.05) in all groups, except the group administered diawell, which was not significantly different (p>0.05), compared to the diabetic control. Mean FPG levels were significantly higher (p˂0.05) in the metformin group, diawell group, but showed no significant difference (p>0.05) in the combination group, compared to the negative control. HOMA-IR was significantly higher (p<0.05) in the diabetic control compared to the negative control and treatment groups. The metformin and diawell groups had significantly higher (p˂0.05) HOMA-IR values, whereas the combination (metformin + diawell) showed no significant difference (p>0.05) when compared to the negative control. TOS was significantly higher (p<0.05) in the diabetic control compared to the negative control and treatment groups. The metformin and diawell groups had significantly higher (p˂0.05) TOS values, whereas the combination (metformin + diawell) showed no significant difference (p>0.05) when compared to the negative control. There was significantly lower (p˂0.05) TAS levels in the diabetic and treatment groups, compared to the negative control. OSI values were significantly lower (p˂0.05) in all groups when compared to the diabetic control. Also, OSI values were significantly higher (p˂0.05) in the treatment groups compared to the negative control. Conclusion: There was depletion of antioxidant parameters and an increase in oxidative stress in the diabetic rats. Administration of metformin and the polyherbal tablet diawell individually, were not effective in correcting the pathological and biochemical changes associated with diabetes. However, the combination treatment produced a better glycaemic response and attenuated the oxidant status in the rats. Antioxidant therapy should be incorporated in diabetes management, and anti-diabetic herbals properly evaluated.

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.

Abstract Background: Oxidative stress and its induced inflammation are important pathological processes of diabetic nephropathy (DN). Oridonin, a component isolated from Rabdosia rubescens, possesses remarkable anti-inflammatory, immunoregulatory properties, it is also a newly reported NLRP3 inhibitor. However, the renoprotective effects of Oridonin and the underlying molecular mechanisms have not been explored in DN. We hypothesized that Oridonin could reduce NLRP3 pathway and ameliorate diabetes‑induced renal fibrosis.Methods: We used STZ-induced diabetic rats combined high-fat diet to establish a T2DM animal model, and then treated with Oridonin (10, 20 mg/kg/day) for two weeks. Kidney function and renal fibrosis were assessed. In addition, the expression of inflammatory factors and fibrotic markers were analyzed by western blot.Results: Oridonin treatment preserved kidney function and markedly limited the renal fibrosis size in diabetic rats. The renal fibrotic markers were inhibited in the 10 mg/kg/day group and 20 mg/kg/day group compared to the T2DM group. Moreover, the expression levels of TXNIP/NLRP3 and NF‑κB pathway were decreased in the Oridonin treatment group compared to non-treated group. Conclusions: The NLRP3-inflammasome inhibitor Oridonin reduces renal fibrosis and preserves kidney function in T2DM rat model, which indicates potential therapeutic effect of Oridonin on DN.
