Abstract: | The cytoprotective effect of piperine on benzoa]pyrene (Ba]P) induced experimental lung cancer was investigated in male Swiss albino mice. Oral administration of piperine (100 mg/kg body wt.) effectively suppressed lung cancer initiated with Ba]P as revealed by the decrease in the extent of lipid peroxidation with concomitant increase in the activities of enzymatic antioxidants (superoxide dismutase, catalase and glutathione peroxidase) and non-enzymatic antioxidant (reduced glutathione, vitamin E and vitamin C) levels when compared to lung cancer bearing animals. Our data suggest that piperine may extend its chemopreventive effect by modulating lipid peroxidation and augmenting antioxidant defense system. |
