Diabetes mellitus is prevalent in many countries of the world, affecting all ages both in developing and developed nations. The use of plants as remedies or preventive therapies has increased over the years. The study investigated the biochemical changes caused by  combined leaf extracts of Vernonia amygdalina (bitter leaf) and Gnetum africanum (okazi leaf) on alloxan induced diabetic wistar rats.Aqueous extracts of the leaves were prepared using the conventional method.Forty male wistar rats weighing 150-180g were  grouped into eight (five rats each). Group 1 was the normal control while diabetes was induced using alloxan (160mg/ kg)in groups 2-8.Group 2 received no treatment while groups 3-7 received varied ratios of the extracts at (BI/OK|10:90%), (BI/OK|30:70%),  (BI/OK|50:50%), (BI/OK|70:30%) and (BI/OK|90:10%). Group 8 was the diabetic control treated with the standard diabetic drug (Metformin). The animals were weighed and blood glucose was determined at 7-day intervals. They were sacrificed on the 28th day and blood samples collected for serum protein, serum electrolyte, urea, creatinine, liver enzymes and markers of oxidative stress analyses.  The results showed steady increase in the body weights (g) of the rats with (BI/OK|70:30)% treated group showing the highest increase (175.40±1.28). The fasting blood sugar (mg/dl) showed timedependent reduction in all the treated diabeti groups with (BI/OK|90:10)% having the highest (56.20±1.65) reduction. There was a significant increase (p<0.05) in total blood protein concentration (g/dl) in all the treated groups. The results of this study showed time and ratio dependent effect on the parameters measured. Since the two plants are staple vegetables in some countries, their utilization particularly in appropriate combinations should be encouraged. Key words: Extracts, bitter leaf, waterleaf, diabetes mellitus, biochemical parameters.

Purpose: To evaluate the effects of an okra-based diet on streptozotocin-induced diabetes mellitus in adult Wistar rats and its mechanism of action.Methods: Wistar rats (6) were administered streptozotocin (50 mg/kg ip) after an overnight fast. Upon confirmation of diabetes mellitus, the animals were fed ad libitum for 21 days with formulated okrabased test diet in place of normal diet. The rats treated similarly with streptozotocin and fed ad libitum with the normal diet served as diabetic control while rats fed on normal diet and not treated with streptozotocin served as the negative control. Thereafter, the rats were sacrificed, fasting bloodcollected and analysed for glucose concentration and biochemical parameters. Pancreas was also excised for histopathological studies.Results: There was a significant increase in body weight, HDL-cholesterol (p< 0.05) but significant decrease in blood glucose (p < 0.05), serum total cholesterol, triglyceride, LDL-cholesterol and VLDLcholesterol concentrations in the okra-fed diabetic treated rats when compared to the diabetic control group. Furthermore, superoxide dismutase activity (SOD) was significantly higher in the diabetic control, and reduced significantly when fed with okra-based diet (p < 0.05). Catalase (CAT) activity was significantly (p < 0.05) decreased in diabetic control and treated group, whereas it was significantly (p < 0.05) increased in normal control rats. There was a significant (p < 0.05) decrease in reduced glutathione levels. The significant (p< 0.05) increase in malondialdehyde in the diabetic group was significantly decrease in the diabetic rats fed with okra-diet. Also serum insulin level was significantly (p < 0.05) increased and serum α amylase activity was significantly (p < 0.05) decrease in the diabetic treated rats. Histology results show that there was damage to the β cells of the pancreas in the diabetic control when compared to normal control, but rats fed okra diet was able to regenerate endocrine β cells.Conclusion: Okra-based diet lowers hyperglycaemia as well as regenerate/repair endocrine β-cells and exocrine tissues of the pancreas damage by streptozotocin Keywords: Abelmoschus esculentus, Diabetes mellitus, anti-diabetic, Insulin, α-amylase, Mechanism

Aim.  To study the morphology of bronchial epithelium in a rodent streptozotocin-induced (STZ) diabetes mellitus. Materials and Methods. . Diabetes mellitus was introduced in 47 white Wistar rats aged 5?6 months (body weight 234.0?2.64 g). 43 white Wistar rats of the same age were used as control subjects (body weight 242.0?2.13). Diabetes was induced by single intraperitoneal injection of STZ (SIGMA, USA) 60 mg/kg in 0.1 M citrate buffer, pH 4.5. Results. A statistically significant decrease in the total epithelial area by 25.9% was observed in the study group, accompanied by a reduction of the supranuclear zone by 22.1% vs. the control group. Conclusion. We found that bronchial mucous membrane in rodents with STZ-induced diabetes mellitus exhibits signs of atrophy and partial loss of mucous production by bronchial secretory cells.

Streptozotocin Induced Diabetes

Study was conducted to evaluate the hepatoprotective effects of Seabuckthorn leaf extract (SLE) supplementation on serum enzymatic levels in streptozotocin (STZ) induced diabetes mellitus in Wistar rats. Thirty-two adult male Wistar rats were divided into four groups namely CON (negative control), SCO (Seabuckthorn control), DCO (Diabetic control), and DSL (Diabetic seabuckthorn treatment group). Diabetes mellitus was induced by single intra peritoneal injection of STZ @ 50 mg/kg body weight in DCO and DSL group of rats. SLE was administered orally @ 100mg/kg body weight for 40 days to SCO and DSL groups. CON served as the negative control. Blood samples were collected from experimental animals on zero, 20th, and 40th days of trial to study liver specific serum enzyme profile viz aspartate amino transaminase (AST), alanine amino transaminase (ALT), alkaline phosphatase (ALP) and acid phosphatase (ACP). Significantly (P less than 0.01) higher levels of all the enzymes studied were observed in experimentally induced diabetic rats in comparison to normal rats. However, in SLE treated diabetic rats (DSL group), significant (P less than 0.01) improvement was observed in all the above enzymes. It may be concluded that SLE exerts hepatoprotective effect in STZ induce Diabetes mellitus in Wistar rats.
