[Changes in the activity of antioxidant enzymes in ischemia and subsequent reperfusion of the myocardium].
Transitory coronary failure of the myocardium was accompanied by a considerable reduction in the activity of superoxide dismutase, glutathione peroxidase and glutathione transferase, with the activity of the enzymes under study being not different in the ischemized and distant from ischemia zones of the myocardium. Reperfusion did influence the activity of superoxide dismutase and glutathione peroxidase after 10 and 40 minutes of ischemia, whereas following 120 minutes of ischemia the activity of superoxide dismutase ascended after 10 and 40 minutes of reperfusion while the activity of glutathione peroxidase remained unchanged.
