Myocardial infarction size and cardiac function at 72 h after reperfusion. (A) Representative mid-myocardial cross sections of TTC-stained hearts at 72 h after reperfusion. Dark blue area (Evan’s blue-stained): nonischemic zone; remaining area: AAR; white area: infracted tissue; red area (TTC-positive): viable myocardium; (B) percentage of area at risk (AAR) to total LV, and infarction area (INF) to AAR at 72 h after reperfusion. Representative M-mode images from individual groups (C), ejection fraction (D), fractional shortening (E), left ventricular internal dimension in diastole (LVIDd) (F) and left ventricular internal dimension in systole (LVIDs) (G) were measured by M-mode echocardiography. H2S concentrations in plasma (H) and in myocardium (I) were measured at 72 h after reperfusion. *P < 0.05 compared with the Vehicle group; #P < 0.05 compared with DATS-MSN group (mean ± SEM, n = 6).
