Diabetic nephropathy (DN) as a leading cause of end-stage renal failure which has become source of concern recently. The aim of this study was to investigate the effect of EAFL on the histomorphology and evaluate its effect on inflammatory markers in Streptozotocin- Induced diabetic Wistar rats. This study was conducted using thirty male Wistar rats. The animals were divided into five groups of 6 rats each (n=6). Group A was the control animals ( administered with 20 ml/kg/day of citrate buffer orally (p.o) stat for 4 weeks. Group B was induced with 65 mg/kg of streptozotocin in citrate buffer intraperitoneally stat and observe for four weeks without treatment. Group C,D and E were the test groups that received 65 mg/kg of streptozotocin in citrate buffer intraperitoneally stat and 20, 40 and 60 mg/kg/day of EAFL respectively for four weeks after induction of diabetes. Descriptive and inferential statistics were used to analyze the data.
The results showed reduction in serum insulin levels in diabetic groups which was reversed to normal when the intervening agent (EAFL) was administered. The histology of the kidneys showed distortion in renal corpuscles which was reversed when EAFL was administered. The immunohistochemistry of kidney tissues in the normal group (A) showed areas of Ag-Ab immunological reactivity, however, there was no reactivity in the diabetic groups.
The study concluded that EAFL has anti glycemic and anti inflammatory effect on the kidneys of Streptozotocininduced diabetic Wistar rats.
