 [Objectives] It has already been reported that moderate aerobic exercise suppresses experimental atherosclerosis and that decreased production of nitric oxide(NO) accelerates experimental atherosclerosis. In this study, we investigated the effect of NO in exercise-trained apolipoprotein E-deficient mice by supplementation of NG-nitro-L-arginine methyl ester(L-NAME).

 [Methods] Atherosclerosis was induced in the mice fed on a high-fat diet. The mice were given free access to L-NAME(0.1mg/ml) in drinking water. Exercise was performed for 30 minutes 3 times per week on alternate days over 8 weeks. Oil red-O staining was carried out in the aorta for all groups, and the atherosclerotic lesions were assessed and compared among the groups.

 [Results] In the control groups, the atherosclerotic lesion in the exercise-group was less severe than in the non-exercise group. In exercise groups, the lesion of the L-NAME-supplemented group significantly increased compared with the control group. However, the difference was not significant among the non-exercice groups. Endothelial nitric oxide synthase(eNOS) expression of the L-NAME-supplemented groups was reduced compared with the control groups.

 [Conclusions] Suppressive effects against atherosclerosis by exercise were restored by the supplementation of L-NAME. Accordingly, it was confirmed that suppression of atherosclerosis by exercise was mediated via NO.
