OP alleviates myocardial ischemia reperfusion injury. A The Animal Experiment Schedule. B The electrocardiogram of rats (n = 10). C The TTC-Even's blue double staining of heart tissue. Infarct size (%) was expressed as the percentage of infarct area relative to the area at risk (AAR). the nonischemic section shown in blue area, red represent risk area, and the infarct region is stained white (n = 3). D The HE is staining of heart tissue (HE, original magnification, 200 ×, Scale bar = 50 µm) (n = 3). E Levels of TNF-α and IL-6 in serum detected by ELISA kits (n = 10). F–H Levels of WBC, NEU and LYM in blood detected by blood analyzer (n = 10). ^#P < 0.05, ^###P < 0.005 vs Sham; ^*P < 0.05, ^**P < 0.01, ^***P < 0.005 vs I/R
