ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of carvacrol pretreatment on myocardial ischemia-reperfusion (I/R) injury and its underlying mechanisms.</p><p><b>METHODS</b>Wild-type male C57 BL/6 mice were randomized into 5 groups (n=13), namely the sham-operated group, vehicle (DMSO in saline)+ I/R group, carvacrol (20 mg/kg) + I/R group, carvacrol (40 mg/kg) + I/R group, and carvacrol (60 mg/kg) + I/R group. The mouse models of myocardial I/R injury were established by a 45-min occlusion of the left anterior descending coronary artery (LAD) followed by reperfusion for 2 h. Carvacrol or vehicle was administered intravenously 15 min before LAD occlusion. After reperfusion, the mice were examined for myocardial oxidative stress level and apoptosis rate.</p><p><b>RESULTS</b>Compared with the vehicle group, the 3 carvacrol-pretreated groups showed significantly reduced myocardial infarct size, oxidative stress level and cardiac myocyte apoptosis rate (P<0.01).</p><p><b>CONCLUSION</b>Carvacrol can protect against myocardial I/R injury by inhibiting myocardial oxidative stress and apoptosis in mice.</p>
