Assessment of urinary markers for CsA-induced oxidative stress. (A) 24 hr urinary 8-iso-PGF2α concentrations from the experimental groups is shown. *p <0.05 vs. other groups. (B) 24 hr urinary excretion of 8-OHdG from the experimental groups. *p <0.05 vs. other groups. 8-iso-PGF2α = 8-epi-prostaglandin F2α; 8-OHdG = 8-hydroxy-2′-deoxyguanosine; VH = vehicle-treated group; VH + OA = vehicle plus oleanolic acid-treated group; CsA = cyclosporine-treated group; CsA + OA = cyclosporine plus oleanolic acid-treated group.
