Abstract

The effects of administration of Embelin (EMB) and Curcumin (CUR) on lipid peroxidation, hepatic glutathione antioxidant defense and hematopoietic cells were examined during N-nitrosodiethylamine (DENA-200 mg kg(-1)body wt, single I.P injection) initiated and Phenobarbital (PB-0.05% in drinking water orally for 13 weeks) promoted hepatocarcinogenesis in Wistar strain male albino rats. DENA/PB-induced hepatic damage was manifested by a significant drop in the hepatic glutathione antioxidant defense, increased lipid peroxidation and histological alterations like dysplasia, and atypical cells with abnormal chromatin pattern. Treatment with Curcumin (100 mg kg(-1)body wt) and Embelin (50 mg kg(-1)body wt) prevented the drop in hepatic glutathione antioxidant defense, decreased lipid peroxidation, minimized the histological alterations induced by DENA/PB, but showed toxic effects on the hematopoietic cells. Results indicate the beneficial effects of Embelin and Curcumin against oxidative tissue damage during chemically-induced hepatocarinogenesis in rats.
