ABSTRACT
Aim To investigate the cardioprotective effects and the possible mechanism of trimetazidine in the risky areas during late reperfusion after acute myocardial infarction in canine.Methods Twenty-four adult dogs were randomized into three groupssham operation group(n=8),late reperfusion group(LR,n=8),late reperfusion after trimetazidine treatment group(LR+TMZ,n=8).Physiological saline was orally given in the sham operation group and LR group and trimetazidine(2 mg?kg-1?d-1) in the LR+TMZ group for fourteen days.After that later,all chests were opened and coronary areteries were exposed.Exceptly shame operation group,the late reperfusion of acute myocardial infarction model was made by ligating the coronary for 10 h,followed by reperfusion of 10 h.Apoptotic index were detected by TUNEL.The Bcl-2,Bax,Cytochrome C and apoptosis-inducing factor(AIF) proteins were detected by immunohistochemistry.Results Compared with those of LR group,myocardial apoptotic index and the expression of Bax,Cytochrome C and AIF proteins in LR+TMZ decreased significantly(all P
