title: Protective effect of Cyclea peltata Lam on cisplatin-induced nephrotoxicity and oxidative damage.
abstract: The aim of the present investigation was to evaluate the protective effect of a 70% methanolic leaf extract of Cyclea peltata Lam on cisplatin-induced renal toxicity. The concentration of creatinine, urea, sodium, and potassium in serum and levels of malonyldyaldehyde (MDA), glutathione (GSH), as well as gluathione peroxidase (GSH-Px), superoxide dismutase (SOD), and catalase (CAT) activities were determined in kidney tissue. The marked cisplatin-induced renal damage, characterized by a significant increase in creatinine and urea levels, decreased in extract-treated group, whereas sodium and potassium levels did not change significantly. C. peltata Lam extract significantly changed the increased MDA level and decreased GSH levels found in rats treated with cisplatin alone. The reduced activities of GSH-Px, SOD, and CAT in groups treated with cisplatin alone were significantly increased by the extract. The protective effect was greater in the post-treated than in the pre-treated group of animals. The results indicate that the post-treatment of C. peltata Lam extract might effectively ameliorate the oxidative stress parameters observed in cisplatin induced renal toxicity and could be used as a natural antioxidant against cisplatin-induced oxidative stress.
