Myocardial Bcl-2 and Bax protein immunostaining. Rats were subjected to 3 h of sham ischemia and reperfusion or 30 min of myocardial ischemia followed by 3 h of reperfusion. Sham, Sham operated group; CON, control group; IL, 30 % intralipid group; EIso, emulsified isoflurane group of 2 ml kg−1. Magnification 400×. Data are presented as mean ± SD. Each group n = 8. PEI, positive expressive index; CI, 95 % confidence interval. *P < 0.05, **P < 0.01 vs sham; † P < 0.05, †† P < 0.01 vs CON; ‡ P < 0.05, ‡‡ P < 0.01 vs IL
