Abstrakt: Berberine (BBR) administration is effective in the management of diabetic nephropathy, but the full mechanism of action has not been comprehensively established. This study investigated the effect of oral administration of BBR on fasting blood glucose (FBG) level, renal function (serum uric acid, urea, and creatinine) markers, arginase and adenosine deaminase (ADA) activities, and endogenous antioxidant level in streptozotocin (STZ)-induced diabetic nephropathy of rats. Non-diabetic and diabetic (induced with 50 mg/kg body weight (bwt) of STZ) rats were treated with 50 and 100 mg/kg bwt of BBR for 14 days. Thereafter, the rats were sacrificed and the kidney was isolated and homogenized. The supernatant was used for the determination of ADA and arginase activities, nitric oxide (NO), and malonylaldehyde (MDA) levels. Antioxidant status of the kidney (superoxide dismutase (SOD), glutathione peroxidase (GPx) activities, and glutathione (GSH) level) was determined. The result indicated that FBG level, as well as serum biomarkers of kidney function, was drastically reduced in diabetic rats treated with BBR when compared to the untreated diabetic rats. Induction of diabetes led to an increase in ADA and arginase activities, and MDA level, with a concomitant decrease of NO level and antioxidant status, compared with the normal control rats. However, treatment with BBR (50 and 100 mg/kg) reversed these effects. In conclusion, oral administration of BBR decreased FBG, ADA and arginase activities, and MDA level, and increased NO and antioxidant in diabetic rats. [ABSTRACT FROM AUTHOR]
