Western blotting analysis of myocardial tissues from each group revealed that, compared to the MI group, MI + Levo group had significantly suppressed Caspase-3 (MI + Levo 0.28 ± 0.02 versus MI 0.46 ± 0.04, p < 0.05) and Bax (MI + Levo 0.76 ± 0.06 versus MI 1.13 ± 0.16, p < 0.05) protein levels as well as elevated Bcl-2 protein levels (MI + Levo 0.87 ± 0.08 versus MI 0.69 ± 0.05, p < 0.05) (Figures 2(e) and 2(f) and Table 8). This evidence concerns the gene BCL2 and myocardial infarction.
