title: Effects of chronic alcohol consumption on myocardial ischemia in rats.
abstract: The effects of chronic alcohol consumption on myocardial ischemia and gas perfusion with 95% O(2)-5% CO(2) were investigated in isolated rat heart. Eighteen adult male Wistar rats were used. Rats were assigned into six groups for each group to contain three rats: normal, alcoholic, normal ischemic, alcoholic ischemic, normal ischemic and 95% O(2)-5% CO(2) perfused, alcoholic ischemic and 95% O(2)-5% CO(2) perfused, respectively. Alcohol (7.2%, v/v) was given to rats by a modified liquid diet for 21 days. Rats were anaesthetized with ketamine (1-2mg kg(-1)). Hearts were quickly isolated. Normal and alcoholic rat hearts were directly sent to the electron microscopic preparation. The other hearts were cut into small pieces and put into Krebs solution. The solution was continuously bubbled using 95% N(2)-5% CO(2) 20 min for ischemia. After removal of normal ischemic and alcoholic ischemic heart specimens for electron microscopic examination, the remaining hearts of the last two groups were bubbled with 95% O(2)-5% CO(2) for another 20 min for the purpose of reperfusion and then were also prepared for electron microscopic examination. The hearts were investigated with a transmission electron microscope (Jeol 100 CXII TEM). Twenty-one days of chronic alcohol consumption was found to have no significant effect on myocardial ischemia determined by transmission electron microscopic examination. Our results suggest that there is no significant relationship between 21 days of alcohol consumption by a liquid diet and myocardial protection.
