    Abstract:
    BACKGROUND: Cisplatin is an effective and extensively used chemotherapeutic agent to treat range of malignancies, but its therapeutic use is limited because of dose-dependent nephrotoxicity and hepatotoxicity. Several published reports advocate that supplementation with antioxidant can influence cisplatin induced hepatic damage. METHOD: In the present study the Wistar rats were subjected to concurrent prophylactic oral treatment of chrysin (25 and 50mg/kgb.wt.) against the hepatotoxicity induced by intraperitoneal administration of cisplatin (7.5mg/kgb.wt.). Efficacy of chrysin against the hepatotoxicity was evaluated in terms of biochemical estimation of antioxidant enzyme activities, histopathological changes and expression levels of molecular markers of inflammation. RESULTS: Chrysin ameliorated cisplatin-induced lipid peroxidation, xanthine oxidase activity, glutathione depletion, decrease in antioxidant (catalase, glutathione reductase, superoxide dismutase, glutathione peroxidase and glucose-6 phosphate dehydrogenase) and phase-II detoxifying (glutathione-S-transferase and quinone reductase) enzyme activities. Chrysin also attenuated expression of COX-2, iNOS and levels of NFκB and TNF-α, and hepatic tissue damage which were induced by cisplatin. Histological findings further supported the protective effects of chrysin against cisplatin-induced hepatic damage. CONCLUSION: The results of the present study demonstrate that oxidative stress and inflammation are closely associated with cisplatin-induced toxicity and chrysin shows the protective efficacy against cisplatin-induced hepatotoxicity possibly via attenuating the oxidative stress and inflammatory response.
