ABSTRACT
Aim Observing the alteration of cardiac myocyte nuclear inositol 1,4,5-trisphosphate receptor (IP_3R)binding proterties in rat subjected to myocardium ischemic reperfusion is to make it clear whether this change is involved in the molecule mechanism of cell apoptosis of rat with myocardial ischemic reperfusion. Method Apoptosis index of myocardial cell was determined using TUNEL assay.Extracting of cardiac myocyte nucleus was accomplished by saccharose density gradient centrifugation method,the binding proterties of nuclear IP_3R in different conditions were detected by radioligand binding assay.Results ①Myocardial cell apoptosis index in rat heart underwent 30 min regional ischemia and 3 h reperfusion was distinctly increased compared with sham-operated group(P
