Some oxidative enzymes of undamaged sites of the left ventricle were examined with the aid of ultrastructural morphometric and quantified cytochemical methods 1, 2, 7 and 14 days after the ligature of the descending branch of the left coronary artery. A comparison of the ultrastrastructural morphometric data with the densitometric data showed that increases in the activities of some oxidative enzymes are accompanied by enlargements of the mitochondria.
