title: [Ultracytochemical heterogeneity of cytochrome oxidase activity in rat cardiomyocytes].
abstract: Optimum conditions are developed for ultracytochemical detection of cytochrome oxidase in cardiomyocytes from the rat heart ventricles. Conditions mentioned above rest on using of o-dianisidine and double contrasting of microscopic sections by uranyl and lead acetates. Data from studies in heterogeneity of cytochrome oxidase activity as dependent on the structural-functional state (electronic density) of myocardium cells are presented.
