| Abstract: | This study was undertaken to evaluate the antioxidant effect of vitamins C and E against oxidative stress, apoptosis and histological changes of kidney and retina in CPF-treated rats. Forty male Sprague-Dawley rats were divided into four groups including the control group, the group treated orally with a single dose of CPF (63 mg/kg b.w.), the group injected intramuscularly (i.m.) with vitamin C (250 mg/kg b.w.), and intraperitonealy (i.p.) with vitamin E (150 mg/kg b.w.) daily for 7 days and the group treated with CPF (single dose) and injected with vitamins (for 7 days). The results showed that CPF induced apoptosis and severe oxidative stress as indicated by the significant increase in MDA and sFasL concentration and the significant decrease in GSH concentration in serum. Co-administration of vitamins C and E ameliorate these toxic effects and improved the histological pictures of kidneys and retinas. It could be concluded that combined administration of vitamins C and E is useful in the routine therapy for the protection against tissue damage induced by CPF. |
