Objectives: The present study was carried out to investigate the protective effects of oral consumption of resveratrol on vanadium induced renal injury in male Wistar rats. Materials and Methods: Animals received either ammonium metavanadate (AMV, 5 mg/ kg/d, (intraperitoneally; 14 consecutive days) or resveratrol solution (10 mg/kg and 50 mg/kg, gastric gavage) along with AMV treatment. The last group received resveratrol alone (50 mg/ kg, gastric gavage) for 4 weeks. Results: AMV injection caused progressive tubular damages resembling acute tubular necrosis. Microscopic views revealed tubular attenuation and blebbing. In addition, progressive peritubular congestion of the capillaries observed while no evidence of renal fibrosis was present in trichrome staining. Further, leve...
