ABSTRACT
AIM:
To investigate the influence of ischemic preconditioning on heart function, the activities of lactate dehydrogenase(LDH), malondialdehyde(MDA), and heme oxygenase-1(HO-1) after ischemia/reperfusion in isolated rat heart.METHODS:
The model of Langendorff was used in isolated rat heart perfusion. Ischemic preconditioning protocol stopping perfusion for 5 minutes and reperfusion for 5 minutes, repeating three times. Ischemia protocol stopping perfusion for 40 minutes and reperfusion for 20 minutes. Indexes of heart function were recorded in control group, ischemia and reperfusion group(IR), and ischemic preconditioning group(IPC). The content of LDH of coronary effluent was measured. Moreover, the content of MDA and activity of HO-1 in myocardium were also measured.RESULTS:
The recovery percentage of heart function in IPC group was significantly higher than that in IR group(P
