Protective effects of erdosteine, vitamin E, and vitamin C on renal injury induced by the ischemia-reperfusion of the hind limbs in rats

To compare the protective efficacy of erdosteine and vitamins C and E against renal injury caused by hind limb ischemia-reperfusion (I/R). Materials and methods: Rats were split into 4 groups: group I as the control, group II as I/R, group III as I/R + erdosteine, and group IV as I/R + vitamins C and E. Superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) activities and malondialdehyde (MDA) tissue levels were determined. Results: MDA levels were found comparable with the control group in groups II and III. However, they were considerably decreased in group IV when compared to group II (P < 0.01). Additionally, SOD, CAT, and GSH-Px activities were considerably (P < 0.05) decreased in group II. While CAT and GSH-Px activities were restored (P < 0.01) by vitamin E and C treatment, SOD activity was not significantly affected. While GSH-Px activities were higher (P < 0.05) with erdosteine administration, SOD and CAT activities were unchanged. Conclusion: The protective effect of vitamins C and E is higher than that of erdosteine treatment in reducing the oxidative stress after renal ischemia in this animal model.
