Abstract

The objective of this study was to compare the effects of a combined treatment consisting of an isoflavone diet and aerobic exercise on the Caspase 9 levels, and Bcl-2 levels during menopause, using 30 S.D ovariectomized rats as a model, over 12 weeks. The ovariectomized rats were divided into 4 experiment groups, with 8 rats in each group, as follows: (1) General diet group (GD, n=8), (2) Isoflavone diet group (ID, n=8), (3) General diet + Exercise group (GEX, n=8), (4) Isoflavone diet + Exercise group (IEX, n=8). The findings of this study were as follows: 1. Combined treatment consisting of an isoflavone diet and regular exercise resulted in a significant reduction in the expression of caspase-9 proteins (p<0.05), and a significant increase in the expression of Bcl-2 proteins (P<0.001). In addition, apoptotic cells were more decreased (p<0.001) in GEX and IEX group. This also suggests that cardiovascular disease in postmenopausal women might be prevented or inhibited to exert positive apoptotic inhibitory effects by increasing Bcl-2 protein expression within aortic tissues during vascular movement and decrease caspase-9 protein.
