Abstract
The purpose of this study was to investigate the efficacy and mechanisms of cardio-cerebral stasis transforming medicines (CCSTM) against cerebral infarction (CI) and myocardial infarction (MI). CI modeling was conducted using the refined Longa suture-occluded technique, while MI modeling was accomplished through the occlusion of the anterior descending branch of the left coronary artery. We found that compared with the model groups, CCSTM decreased the infarct size in models of CI and MI in a dose-dependent manner. After brain ischemia, CCSTM decreased the level of myeloperoxidase (MPO) and malondialdehyde (MDA), and increased the level of superoxide dismutase (SOD). Besides, CCSTM reduced the concentrations of lactate dehydrogenase (LDH), malondialdehyde MDA, and endothelin (ET) in the plasma of rats injured with MI. Histological examination of brain sections revealed that CCSTM alleviated cerebral damage after ischemia compared with the model group. CCSTM can reduce myocardial and cerebral infarction injury, and the oxidation level after myocardial and cerebral infarction in rats.
