In this Study, it was aimed to investigate the protective effect of caffeic acid phenethyl ester (CAPE) oil cisplatin hepatotoxicity. Thirty New Zealand rabbits were divided into 5 groups as group 1 (saline-injected control, C), group 2 0% ethanol; vehicle for CAPE, E), group 3 (CAPE), group 4 (cisplatin, CS) and group 5 (cisplatin Plus CAPE, CS + CAPE). Cisplatin caused increased immunoreactivity against inducible nitric oxide synthase (iNOS), but CAPE treatment reduced the immunoreactive hepatocytes. Liver malondialdehide (MDA), nitric oxide (NO(center dot)) levels and xanthine oxidase (XO) activities were higher in CS than in groups C and E. Cisplatin treatment also significantly decreased the tissue reduced glutathione (GSH) concentration compared to groups C and E. CAPE administration normalized the tissue GSH level and XO activity in group CS + CAPE, whereas CAPE treatment did not affect MDA level In group CS + CAPE. In addition, CAPE treatment significantly depressed the cisplatin-induced NO(center dot) increase in group CS + CAPE. Histopathologically, cisplatin caused hydropic degenerations, necrosis in hepatocytes, sinusoidal congestion, Kupffer cell proliferation and mononuclear cell infiltration. These alterations were less severe in rabbits receiving CS+CAPE. Parallel to histopathology, cisplatin increased serum AST and ALT levels, whereas CAPE treatment significantly reduced cisplatin-induced AST and ALT rise in the serum.
