Effects of simvastatin on apoptotic cell death. a TUNEL staining was performed on lung tissues from different treatment groups (scale bar: 10 μm). Quantification of TUNEL staining was also calculated. b The apoptotic proteins Bax and Bcl-2 measured by western blotting. The data are presented as the means ± SD. a P < 0.05 vs. the S group; b P < 0.05 vs. the LV group. N = 12 per group
