Effects of peroxisome proliferator-activated receptor ? activator rosiglitazone on myocardial ischemic-reperfusion injury in rats / 中国病理生理杂志

AIM: To investigate the effect of peroxisome proliferator-activated receptor ? (PPAR?) activator rosiglitazone on myocardial ischemic-reperfusion injury in rats. METHODS: Forty-two SD rats were randomly divided into three groups: sham group (n=14), I/R group (n=14) and I/R+rosiglitazone group (n=14). Myocardial infarct size was assessed by NBT staining. Plasma and myocardial angiotensin and aldosterone as well as plasma renin activity were detected by radioimmunoassay. RESULTS: Compared with I/R group, myocardial infarct size was reduced by 23.9% (P
