Effects of Nicardipine on Apoptosis in Ischemia Reperfusion Myocardium of Rabbits / 中国医科大学学报

ABSTRACT

Objective To investigate the effects of nicardipine on apoptosis in ischemia?reperfusion myocardium of rabbits. Methods Forty New Zealand rabbit were randomly divided into 4 groups:control group(group A),ischemia group(group B),ischemia?reperfusion group(group C),ni?cardipine treatment group(group D). Ischemia?reperfusion model was established by left circumflex branch coronary artery ligation for 40 min,fol?lowed by 120 min reperfusion. Apoptotic cardiomyocyte was detected using the analysis for the exposure of phosphatidyl?serine ( Annexin V)meth?od. Results Myocardial cell damage was lower in D group than that in group B and group C from pathology(P0.05). Conclusion Nicardipine horizon can reduce the myocardial cell apoptosis in rabbits with myocardial ischemic reperfusion injury.
