Pretreatment with vitamin E (50 mg/100 g body wt., once a week for 3 weeks) was carried out before the administration of cyclosporin A and ammonium oxalate. Nonenzymatic ascorbate-induced lipid peroxidation was increased to 1.55-fold in either cyclosporin A-administered or hyperoxaluric rat kidney and liver when compared to control. The lipid peroxidation was further elevated to 1.9-fold when both cyclosporin A and ammonium oxalate were coadministered. The activities of renal and hepatic ATPase, glucose-6-phosphatase as well as the concentrations of thiols were decreased significantly (p < 0.001) when cyclosporin A was administered under hyperoxaluric condition.
