[Electron-microscopic autoradiography of RNA synthesis in the myocardium after damage to it].
Thermic burn of the wall of the left cardiac ventricle was inflicted to new born rats. Twenty-four hours after the injury the RNA synthesis of the myocardial cells remote from the site of burn were investigated by electron-microscopic autoradiography. Tissue samples were fixed 2 and 6 hours after the 3H-uridine injections. As compared with the control, experimental animals displayed a reduction of silver grains density over the nucleus and the cytoplasm of cardiomyocytes.
