Oxidative stress and apoptosis are 2 major characteristics of the progression of atherosclerosis. Both lovastatin and Magnolia officinalis are hypocholesterolemic agents. Therefore, we investigated the effect of M. officinalis extract on the prevention of atherosclerosis in comparison with lovastatin. Twenty hyperlipidemic rabbits were served one of the following diets: a high-fat and cholesterol diet (cholesterol group, 10% corn oil and 0.5% cholesterol), a high fat and cholesterol diet supplemented with M. officinalis extract (300 mg/kg) or lovastatin (6 mg/kg). The plasma lipids, oxidative stress (measured by free radical, malondialdehyde, and oxidative DNA damage), and arterial lesions significantly decreased in the M. officinalis and lovastatin groups when compared with the cholesterol group. Moreover, the expressions of Fas ligand, caspase 8, and caspase 9 in the aortic arches were also markedly lowered after M. officinalis and lovastatin supplements. Therefore, the results indicate that the antiatherogenic effect of M. officinalis is involved with a suppression of oxidative stress and with the down-regulation of apoptosis-related gene expression in hyperlipidemic rabbits.
