[Role of changes in oxygen concentration during modification of cell reproductive death in vitro. 2. Modification of radiosensitivity during changes in the rate of oxygen consumption by cells].

A study was made of the role of changes in the concentration of oxygen occurring upon modification of radiosensitivity of cells in vitro using temperature (0-37 degrees C), incoupling agents and respiration inhibitors, and also upon stimulation of the oxygen consumption by microsomes. When cells were irradiated in suspension, monolayer, spheroid and roots of plants a change in the rate of the oxygen consumption by cells and a corresponding change in their oxygenation can contribute considerably to a radiomodifying effect.
