Curcumin (CMN) is known to have beneficial role in anorexia, coryza, cough, diabetic wounds, and hepatic disorders apart from its inherent antioxidant effects. Therefore, the present study was aimed to evaluate antioxidant effect of CMN in prevention of nephrolithiasis in rats-induced by ethylene glycol (EG) and Vitamin D3 (Vit. D3). Male Wistar rats (175 - 200 g) were randomized in groups like control, EG + Vit. D3 induced nephrolithiatiatic rats, CMN treated rats, CMN + EG + Vit. D3 treated rats, Vit. E + EG + Vit. D3 treated rats. Urine was collected weekly throughout the experimental protocol and estimated for calcium oxalate (CaO) count. After completion of experimental protocol serum was estimated for blood urea nitrogen and creatinine. Both the kidneys were excised and used to evaluate levels of biomarkers of oxidative stress and calcium oxalate crystal deposition by histopathological studies. Administration of EG and Vit. D3 to rats resulted in increased oxidative stress, hyperoxaluria and renal deposition of CaO crystals. Supplementation with CMN improves kidney function, reduces elevated oxidative stress, urinary oxalate level and renal deposition of CaO which shows its protective action in nephrolithiasis. The increased deposition of stone in the kidney and stone forming constituents of nephrolithiatic rats were effectively lowered by treatment of CMN.
