title: The effect of lovastatin on oxidative stress and antioxidant enzymes in hydrogen peroxide intoxicated rat.
abstract: Oxidative stress has been linked to the development of many diseases and hastens the progression of cardiovascular diseases. Since lovastatin is used worldwide as a cholesterol lowering drug, the present study was undertaken to evaluate the antioxidant property of lovastatin against H(2)O(2) induced oxidative stress in rats. Four study groups of rats of four animals each were treated with DMSO (control), H(2)O(2) (OS), lovastatin (L) and H(2)O(2) + lovastatin (OSL). On the 15th day the animals were sacrificed, and the liver and heart tissues were analyzed for oxidative stress biomarkers and anti-oxidant enzymes. Results of the OSL-group showed a reduction in thiobarbituric acid reactive substances in liver (42.7%) and heart tissue (8%) compared with the control group. An increase was observed in the activity of the antioxidant enzymes, catalase (34.6% in liver and 33.3% in heart) and glutathione peroxidase (50.5% in liver and 34.7% in heart). A commensurate increase in the activity of G6PDH was observed indicating an enhanced requirement of NADPH. The ratio GSH:GSSG in liver (1.05) and heart (0.84) was satisfactorily regulated compared to the control group (1.01 in liver and 0.93 in heart). These results suggest that lovastatin possesses antioxidant activity and reduces oxidative stress.
