title: [Aminoacyl-tRNA-synthetases and their high molecular weight complexes in experimental myocardial ischemia].
abstract: A number of aminoacyl-tRNA synthetases from rabbit liver during experimental myocardial infarction and from pig myocardium upon 15-min of autolysis were found to increase their activity in aminoacylation. Direct correlations between the activities of high molecular weight complexes and of the total extracts were not observed. It was shown that the specific activity of endogenous inorganic pyrophosphatase increased markedly during the ischemia of myocardium both in total myocardium extracts and in high molecular weight complexes.
