[Microspectrophotometric study of oxidative enzyme activity in experimental myocardial ischemia].
The method of comparitive microspectrophotometry was used to study the changes in the activity of oxidative enzymes in the zone of ischaemia and the juxtaischaemic region of the cardiac muscle in rabbit experiments (104 animals, including 10 controls). A certain periodicity was noted in the changes of the activity of oxidative enzymes in separate zones of the ischaemic myocardium during different periods of the infarction development and healing. The terms of maximum reduction of the enzymatic activity falling within the 4th-6th and 24th hours and 2nd day should be taken into account while developing the methods of metabolic protection and enzyme therapy of the ischaemic myocardium.
