[Changes in phospholipid metabolism in subcellular structures of cardiac muscle of rabbits with experimental myocardial infarction].

Alteration in phospholipid turnover was studied in subcellular structures (nuclei, mitochondria, microsomes) of rabbit heart muscle within various postinfarctional periods (7, 14 and 21 days). The specificity of alterations in phospholipids as well as dissimilar direction of the alterations were observed in different subcellular structures of heart cells under conditions of myocardial infarction. Administration of etpenale contributed to increased synthesis of phospholipids (especially in mitochondrial fraction) with subsequent trend to normalization.
