[The cell cycle patterns of the hemopoietic cells under the action of ionizing radiation].

Abstract

The analysis of changes in bone marrow cell cycle induced by ionising radiation in animals and humans in comparison with myelogram evidence on postradiation death of myelocaryocytes shows that radiation is responsible for pronounced dose-dependent shifts in cell cycle early after radiation prior to postradiation cell death. These phenomena are considered in light of new hypophysis on the existence of cell cycle regulation system and initiation of apoptosis at the cell level.
