This study was performed to investigate the protective effect of combined use of Vitamins E and C on colistin-induced tubular damage in rat. Animals were treated with sterile saline, colistin methanesulfonate (CMS), CMS + Vitamin E + Vitamin C, and Vitamin E + vitamin C, respectively, for seven days. Thereafter, animals were sacrificed and the urine N-acetyl-b-D-glucosaminidase (NAG) and gamma-glutamyl transferase (GGT) levels, plasma level of creatinine (Cr), vitamin E and vitamin C, and renal tissue levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx), as well as renal histology were performed. CMS induced acute tubular necrosis, increased the NAG, GGT, and MDA levels, and reduced the Vitamin E, Vitamin C, SOD, CAT, and GPx activities. Co-treatment with vitamins E and C restored all biochemical parameters cited above and improved the histopathological damage. Tubular damage induced by colistin is at least partly due to oxidative stress. Nephroprotective effect of Vitamins E and C is partially mediated through its antioxidant properties, and the higher protection by the combination of these vitamins is related to its synergistic effects.
