Abstract:
AIM: The changes of myocardial nuclear membrane Ca 2+ -ATPase function was investigated in ischemia/reperfusion injury. METHODS: The model of myocardial ischemia/reperfusion injury was established in rats. Myocardial nuclei were purified with sucrose density centrifugation,the activity of Ca 2+ -ATPase was measured and calcium uptake was assayed with [ 45 Ca 2+ ] . RESULTS: Plasma levels of malondialdehyde (MDA) and free fatty acid (FFA) in myocardial ischemia/reperfusion injury increased significantly( P
