title: Effect of asparagine and arginine on the repair of isoprenaline-damaged myocardium of rat.
abstract: The effect of asparagine and arginine on the repair of isoprenaline-damaged myocardium was studied. In group I (treated with isoprenaline) the rats developed large foci of myocardial damage filled by connective tissue after 14 days. Similar changes were observed in group II (isoprenaline + asparagine). In group III of rats treated with isoprenaline and arginine the number of foci of injury and their size were smaller, and only a few small foci fibrosis were found after 14 days. Arginine seems to protect the rat myocardium from isoprenaline-induced damage. The repair by connective tissue is supplemented by compensatory hypertrophy of muscle fibers.
