title: [Seasonal changes in several ultrastructural indices of lake frog heart ventricle myocytes].
abstract: The method of electron microscopy with morphometric analysis was applied to the study of some ultrastructural indices of frog heart (ventricle) myocardium - the interlocated discs, the lateral junctions and mitochondria - in spring and in autumn. The results obtained pointed to seasonal differences in the cardiomyocyte ultrastructure, this being confirmed by the quantitative analysis.
