The present work was conducted to study the protective effect of ginger extract (GE) against the hepatotoxicity induced by 7, 12-dimethylbenz(a)anthracene (DMBA) in female rats. DMBA treated group showed a highly significant decrease in body weight. However, DMBA+GE treated group displayed a highly significant increase in body weight compared with DMBA treated group. Histologically, the liver of DMBA treated group showed nodule-like structures, hepatic cirrhosis, congestion of blood vessels, intercellular hemorrhage, hepatic pyknotic nuclei, lymphocytic infiltration, dilation of blood sinusoids and large amount of collagen fibres. DMBA+GE treated group displayed an improvement in the hepatic lesions induced by DMBA. Histochemically, the liver sections of DMBA treated group showed a marked depletion of polysaccharides and total protein content. However, DMBA+GE treated group showed a moderate increase in liver polysaccharides and total protein contents. Immunohistochemically, the hepatocytes of DMBA treated group showed a highly significant increase in the PCNA labelling index. However, DMBA+GE treated group displayed a highly significant decrease in the PCNA labelling index when compared with DMBA treated group.
