DEX reduces myocardial infarct size in rats. Myocardial infarct size was detected by Masson trichrome staining. (a) Masson staining and myocardial infarction area of rats in each group; the red area represented normal myocardial tissues, while the blue area represented an infarcted myocardium (scale bar = 50 μm). (b) The bar graph of myocardial infarct size: infarct size (%) = (myocardial infarct size/total left ventricular area) × 100%. All results are expressed as the mean ± SD. ^∗P < 0.05 between each group.
