The АТР-ase activity and swelling intensity of mitochondria are determined in livers of rats with tumor and preliminarily irradiated rats with tumor. It is shown that, at the initial stages of oncogenesis under low doses of the preliminary irradiation, the main factor of changes in the permeability of liver mitochondrial membranes and the АТР-ase activity in rats with tumor is the radiation influence. At the terminal stages, the main factor is the neoplasm influence.
