RESUMEN

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. 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. 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. 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.
