The Effects of Ginkgo Biloba Extracts on the Nephropathy of Diabetic Rats Induced By Streptozotocine (STZ)
Abstract
This study was designed to evaluate the effects of Ginkgo biloba extracts on the kidneys of diabetic rats induced by streptozotocine (STZ). 40 adult male Wistar albino rats were examined. Rats were divided into four groups as control, diabetic group, Ginkgo biloba administered diabetic group and group exposed to solvent only. Experimental diabetes was induced by intraperitoneal application of 60 mg/kg STZ to diabetes group and Ginkgo biloba administered diabetes group. After the induction of diabetes, every day 100 mg/kg Ginkgo biloba extract was administered orally to the ginkgo group for 40 days. Throughout the experiment blood glucose levels and body masses of the rats was monitored. On the 40th day rats were decapitated under ether anesthesia and their kidneys were removed. The tissue samples were embedded in paraffine. After histochemical staining the sections were investigated under lightmicroscopy. While blood glucose level of the diabetes group was significantly higher compared with the control and solvent groups, the body mass significantly decreased. Basic glomerular and tubular histologic changes caused by diabetes, like thickening of the basal membrane, expansion of the mesenchymal matrix, glomerulosclerosis, tubular necrosis, hydropic degeneration, cellular swelling, vacuolization, were observed. These changes were observed significantly less in the Ginkgo biloba group Gingko biloba extract (Egb 761) decreased kidney damage in diabetic rats induced with STZ. We therefore believe that Ginkgo biloba extracts may help preventing the development of kidney damage and decrease the amount of pathologic findings in diabetes. Further studies are still necessary to demonstrate the efficacy of long term Ginkgo biloba use on diabetic complications.
