title: Protective effects of capsaicin against cisplatin-induced nephrotoxicity in rats.
abstract: Cisplatin-induced nephrotoxicity is related to an increase in lipid peroxidation and oxygen free radicals in a kidney. In the present study, we investigated the effect of the dietary antioxidants, capsaicin (Cap), against cisplatin-induced lipid peroxidation and nephrotoxicity in rats. Nephrotoxicity induced by treatment with a single dose of cisplatin (5 mg/kg body weight i.p.). The animals were divided into 4 groups. Cap (10 mg/kg/d) was given by gavage from the same day of cisplatin injection. Cisplatin administration resulted in significant increases in the kidney weight as a percentage of the total body weight, urine volume, serum creatinine, and blood urea nitrogen by about 132, 315, 797, and 556% in comparison with the control rats, respectively (p < 0.05). Also, the renal tissue from the cisplatin-treated rats showed significant decreases in the kidney glutathione (GSH) content and superoxide dismustase (SOD) activity and a significant increase in malondialdehyde (MDA) production in comparison to the values at 0 h (p < 0.05). Seven days after Cap plus cisplatin treatments, the renal damage induced by cisplatin recovered to a significant statistically level. In addition, Cap prevented the rise of MDA and the reduction of SOD activities. These results suggest that Cap has protective effects against cisplatin-induced nephrotoxicity and lipid peroxidation in rats.
