Antidiabetic and Nephroprotective Activity of Hedychium spicatum in Streptozotocin-Induced Diabetic Rats

Background: The leaves of Thaumatococcus danielli (Benth.) have been traditionally used in folk medicine to treat malaria in Nigeria. However, there is no report on whether these leaves contain Nephroprotective activity. Thus, the ethanol leaf extract was investigated for Nephron-protective activity in Streptozotocin induced diabetic rats.Methods: First, the LD50 of the leaf was determined using standard procedure. Rats were assigned to 5 groups (A-E) of five rats. Except for the control group, each group was made diabetic using Streptozotocin (65 mg/kg/b.wt. i p). The treated groups received 0.5 ml of glibenclamide (25mg/kg/b.wt, o.p), 250 and 500 mg/kg/b.wt, o.p of Thaumatococcus danielli respectively. After 14 days of treatment, animals were sacrificed under light anaesthesia. Data were expressed as Means ± S.D (n=5) and were analyzed using one-way ANOVA followed by Dunnet’s test, values were considered significant at p<0.05. Results: The plant showed a LD50 greater than 5000 mg/kg/b.wt in albino rats observed for 72 hours. A significant (p<0.05) decreased in serum Na+, Cl-, HCO-3, total protein, and an insignificant increase in K+, urea and creatinine level were observed in the diabetic group when compared with the normal group. Oral administration of plant extract and glibenclamide significantly (p<0.05) restored the electrolytes to near normal. Histological alterations such as glomerulonephritis, and tubules infiltration by inflammatory cells observed in diabetic control were also reversed.Conclusion: This study suggests renal protective ability of the plant against impairment due to hyperglycemia.Keywords: Streptozotocin, Thaumatococcus danielli, Nephroprotective, Glibenclamide, serum electrolytes.

Abstract Background and Aims Diabetes mellitus is a chronic metabolic disease affected a wide range of population all over the world and leads to development of secondary complications. Enzymes play key role in the development of secondary complication. Method The flavonoid rich fraction was prepared using ethyl acetate. Oral glucose tolerance test normoglycemic effect of flavonoid rich fraction of Hybanthus enneaspermus (EHE) was evaluated at a dose of 45 and 90 mg/kg, p.o. Further effect of EHE on blood glucose, body weight, enzymes such as super oxide dismutase (SOD), catalase and thiobarbituric acid reactive substances (TBARS) and lipid parameters were estimated out at 45 and 90 mg/kg p.o. per day for 21 days in streptozotocin-induced type-2 diabetic rats. Molecular docking technique was also performed against Super Oxide Dismutase (SOD), Catalase, Glutathione Peroxidase (Gpx), xanthine oxidase and nuclear factor kappa B (NF-κB) for selected phytoconstituents. Results EHE contain significant amount of phenolic, tannin, flavonoid and saponin. EHE significantly decreased blood glucose level in diabetic rats. All the tested lipid parameters and enzyme level of SOD, Catalase and Gpx were significantly restored to the normal level in the EHE treated rats. Moreover, there was a significant increase in the body weight in the EHE treated rats. Docking study showed the best binding affinity and interaction of phytoconstituents with xanthine oxidase and NF-κB signified their role in kidney disorders. Conclusion EHE has very impressive profile as an antidiabetic, antioxidant and nephroprotective activity via enzymes modulation and it may prove to be effective treatment for kidney disorders in hyperglycemia.

Some investigators feel that insulin does not enter cells but exerts its influence in some manner on the cell surface. Ferritin labeling of insulin and insulin antibody was used to determine if binding sites of insulin to specific target organs could be seen with electron microscopy.Alloxanized rats were considered diabetic if blood sugar levels were in excess of 300 mg %. Test reagents included ferritin, ferritin labeled insulin, and ferritin labeled insulin antibody. Target organs examined were were diaphragm, kidney, gastrocnemius, fat pad, liver and anterior pituitary. Reagents were administered through the left common carotid. Survival time was at least one hour in test animals. Tissue incubation studies were also done in normal as well as diabetic rats. Specimens were fixed in gluteraldehyde and osmium followed by staining with lead and uranium salts. Some tissues were not stained.

Abstract. Objective: This study aimed to evaluate the effect of maternal consumption of flaxseed flour and oil on serum concentrations of glucose, insulin, and thyroid hormones of the adult female offspring of diabetic rats. Methods: Wistar rats were induced to diabetes by a high-fat diet (60%) and streptozotocin (35 mg/kg). Rats were mated and once pregnancy was confirmed, were divided into the following groups: Control Group (CG): casein-based diet; High-fat Group (HG): high-fat diet (49%); High-fat Flaxseed Group (HFG): high-fat diet supplemented with 25% flaxseed flour; High-fat Flaxseed Oil group (HOG): high-fat diet, where soya oil was replaced with flaxseed oil. After weaning, female pups (n = 6) from each group were separated, received a commercial rat diet and were sacrificed after 180 days. Serum insulin concentrations were determined by ELISA, the levels of triiodothyronine (T3), thyroxine (T4) and thyroid-stimulating hormone (TSH) were determined by chemiluminescence. Results: There was a significant reduction in body weight at weaning in HG (−31%), HFG (−33%) and HOG (44%) compared to CG (p = 0.002), which became similar by the end of 180 days. Blood glucose levels were reduced in HFG (−10%, p = 0.044) when compared to CG, and there was no significant difference between groups in relation to insulin, T3, T4, and TSH after 180 days. Conclusions: Maternal severe hyperglycemia during pregnancy and lactation resulted in a microsomal offspring. Maternal consumption of flaxseed reduces blood glucose levels in adult offspring without significant effects on insulin levels and thyroid hormones.
