ABSTRACT
OBJECTIVE:
To study the improvement effects of baicalein against myocardial ischemia/reperfusion(I/R)injury in rats.METHODS:
I/R injury model was induced by Langendorff method. Isolated heart of 40 rats were randomly divided into nor-mal group(continuous perfusion),model group(perfusion withdrawal 20 min)and baicalein high,medium and low concentration groups (K-H solution of baicalein 40,10 and 2.5 μmol/ml 10 min before perfusion withdrawal). The myocardial infarction rate, the activity of creatine kinase(CK)and lactate dehydrogenase(LDH)in coronary effluent liquid,SOD activity and MDA content, GSH/GSSG and apoptosis rate of cardiac muscle cell in myocardial tissue were detected.RESULTS:
Compared with normal group, the myocardial infarction rate,apoptosis rate of cardiac muscle cell,the activities of CK and LDH and the content of MDA in myo-cardial tissue were increased in model group,while SOD activity and GSH/GSSG of myocardial tissue decreased(P0.05).CONCLUSIONS:
Baicalein has cer-tain improvement effect on myocardial I/R injury in rats,and its mechanism may be associated with antioxidant and anti-apoptosis effect of baicalein.
