  Objective: This study was conducted to scientifically evaluate the antidiabetic and antioxidant effects of ethanolic leaf extract of Erythrina abbysinica (EEA).Methods: Acute and sub-chronic effects of EEA at 100, 200, and 400 mg/kg/bwt and glibenclamide (GL) at 5 mg/kg/bwt. were evaluated in both normal and streptozotocin (STZ)-induced diabetic male Wistar rats (250–300 g). The acute studies were performed using oral glucose tolerance test (OGTT). In sub-chronic studies, animals were orally administered with EEA and GL daily for 6 w. Brine shrimp assay was used to determine the toxicity of EEA. 1, 1-diphenyl-2-picrylhydrazyl, ferric reducing capacity of plasma, and thiobarbituric acid reactive substances assays were used to determine antioxidant properties of EEA.Results: Following OGTT, EEA significantly (p<0.05) and dose-dependently (100, 200, and 400 mg/kg/bwt) decreased blood glucose levels in both normal and STZ-induced diabetic rats when compared with positive and negative control counterparts at all-time points, whereas GL significantly (p<0.05) decreased blood glucose only in normal rats but not in diabetic rats. Daily, oral administration of EEA for 6 w significantly (p<0.05) and dose-dependently (100, 200, and 400 mg/kg/bwt) decreased blood glucose levels in STZ-induced diabetic rats when compared with the diabetic control group. EEA revealed weak toxicity with a lethal concentration50 value of 997 μg/ml). Furthermore, EEA showed significant free radical scavenging, total antioxidant, and anti-lipid peroxidative capacities.Conclusion: The study has shed more light on the scientific basis for the use of E. abbysinica in management of diabetes in some communities of Eastern Cape of South Africa.

Objective: To study and compare the effect of Poly herbal plant extract (PHPE) with Glibenclamide (GL) on various parameters in Streptozotocin (STZ) induced diabetic rats. Methods: Diabetes was induced by combining High Fat-diet and injecting low dose Streptozotocin (35 mg/kg body wt.) to Sprague-dawley rats. Diabetic rats were treated with chloroform leaf extract of Azadirachta indica, aqueous leaf extract of Bougainvillea spectabilis and ethanolic seed extract of Trigonella foenum graecum combined in ratio of 1:2:3 respectively at dose of 600 mg/kg body weight by oral gavaging for 28 days. The results were compared with standard anti diabetic drug Glibenclamide given in dose of 500 µg/kg body weight. Results: Increase in body weight of both PHPE and GL treated diabetic rats was found to be statistically significant (p<0.05) compared to diabetic control rats. Decline in FBG levels of both PHPE and GL treated diabetic rats were found to be highly significant statistically (p<0.001) when compared to diabetic control rats at the end of study. Total Cholesterol (TC) and Triglycerides level in diabetic rats treated with PHPE were found to be highly statistically significant (p<0.001) compared to diabetic control rats. Pancreas of PHPE treated diabetic rats revealed partial restoration in size and number of islet of langerhans. Reduction in widening between acinar and islet cells noted. Glibenclamide treated diabetic rats showed much more improvement in pancreatic cell architecture by returning to its normal structure and size. Conclusion: In present study PHPE has shown to decrease elevated FBG level and improve in body weight at the end of study in diabetic rats which can be suggested due to modification in carbohydrate metabolic pathways, stimulation of insulin production by the pancreas, increased peripheral utilization of glucose in the cells and regeneration of β-cells of the pancreas.

Diabetes mellitus is an endocrine and metabolic disorder of humans and animals characterized by hyperglycemia and low blood insulin levels or insensitivity of target organs to insulin and it’s a major health problem affecting patient’s quality of life due to its many complications. Infertility is one of the major secondary complications in diabetes. Although numerous drugs have been used for intervention studies on diabetes-induced infertility worldwide, there are currently no treatments for diabetes associated infertility in humans. This study was performed to investigate the effects of Annona muricata ethanolic leaf extract (AMELE) on fertility of male diabetic rats and levels of blood glucose. Twenty male Wistar rats (150-200g) were randomly distributed into 4 groups (n=5) treated thus: CTRL (control), DNT, DT1 and DT2 (diabetic, single intraperitoneal injection, streptozotocin, 60 mg/kg). Group DT1 and DT2 received AMELE orally at 100 mg/kg and 200 mg/kg respectively daily for fourteen days. Data were analysed using ANOVA at α0.05. The animals were sacrificed after 2 weeks via thiopental injection and testicular weights were recorded. Fasting blood glucose was determined using a digital glucometer. Sperm count, motility, viability and morphology were assessed microscopically. Testes were histologically evaluated. The results showed that oral administration of AMELE at 100 mg/kg and 200 mg/kg to diabetic male rats for fourteen days significantly decreased blood glucose level and also ameliorated diabetes-induced decreases in sperm functions in streptozotocin-induced diabetic male rats.
