a Western blots of quantification of Bax, Bcl-2 and active caspase-3 protein levels of myocardial tissue in the sham, saline and sildenafil groups at 24 h after ROSC. b Expressions of Bcl-2/Bax proteins of myocardial tissue at 24 h after ROSC. c Quantification of mRNA expressions of caspase 3. The value represent mean ± SD. *p < 0.05, **p < 0.01 vs. sham, #p < 0.05 vs. saline (one-way repeated-measures ANOVA).
