Sustained limitation by superoxide dismutase of canine myocardial injury due to regional ischemia followed by reperfusion.


This study was performed to evaluate the effects of superoxide dismutase, a scavenger of superoxide anions, on leukocyte accumulation and myocardial injury in a canine preparation of myocardial infarction. Dogs underwent occlusion of the left circumflex coronary artery for 90 min, followed by a reperfusion for 6 or 24 h. The dogs received either saline or… (More)
