Then, the myocardial infarction model was established.The hemodynamic of rats was tested, the serum lactate dehydrogenase (LDH),creatine kinase-MB (CK-MB), prostacyclin (PGI2) and thromboxaneA2 (TXA2) were determined, the myocardialsuperoxide dismutase (SOD) and malondialdehyde (MDA) levels were detected,and the myocardial B-cell lymphoma-2 (Bcl-2) and Bcl-2 associated X (Bax)protein expressions were determined. Here, SOD1 is linked to myocardial infarction.
