We tried to assess the effects of treating rats with estradiol or testosterone on the develop\u00adment of myocardial damage caused by ischemia\/reperfusion. Experiments were carried out on the isolated hearts of sexually mature rats of both sexes (230\u2013330 g) which were perfused with aerated Krebs-Henseleit solution for 30 minutes and then subjected to 40 minutes zero-flow ischemia followed by 55 minutes of reperfusion.<\/p>\n<p>The severity of myocardial damage was assessed based on postischemic changes in the following registered parameters: coronary blood flow, lactate dehydrogenase release rate, left ventricular pressure, heart rate and duration of ventricular fibrillation during reperfusion.<\/p>\n<\/div>\n<p>The coronary flow was higher in the hearts of rats treated with estradiol or testosterone than in those from the control groups. Postischemic LDH values were elevated in all groups, but the highest values were observed in the postgravid group. Postischemic heart rate val\u00adues were lower than before ischemia. The highest values were observed in the postgravid group.
