Abstract

Background. Nitric oxide (NO) concentration in serum is altered by cisplatin (CP), and NO influences CP-induced nephrotoxicity. The effect of nephroprotectant agent supplementation (vitamin E, human recombinant erythropoietin (EPO), or n-acetylcysteine (NAC)) on the NO metabolites levels after CP administration in the two genders was determined. Methods. Sixty-four adult Wistar rats were randomly divided into 10 groups. Male and female rats in different groups received vehicle (saline), CP (7 mg/kg) alone, CP plus EPO (100 IU/kg), CP plus vitamin E (250 mg/kg), and CP plus NAC (600 mg/kg). CP was administrated as a single dose, but the supplementations were given for a period of 7 days. Results. In male rats, the serum levels of total NO metabolites (NOx) and nitrite were increased significantly ( ) by CP. However, vitamin E significantly reduced the serum levels of these metabolites, which was increased by administration of CP ( ), and such findings were not observed for female rats. The EPO or NAC did not influence NO metabolites neither in male rats nor in female rats. Conclusion. Although vitamin E, EPO, and NAC are reported to be nephroprotectant agents against CP-induced nephrotoxicity, only vitamin E could reduce the level of all NO metabolites only in male rats.
