title: [Early changes in intracellular ATP concentration after 5 Gy irradiation by routine regimen and regimen modified by low doses (0.1+4.9 Gy)].
abstract: Comparative studies were made of immediate (within the first minutes) changes in intracellular ATP concentration after irradiation by different regimens. ATP concentration in cells at a stationary phase of growth increased immediately after irradiation with a dose of 5 Gy, reaching its maximum within 30-40 min. Irradiation with the same total dose, by the regimen of 0.1 + 4.9 Gy at a 3-minute interval between the doses, did not cause alterations in the ATP content in cells. It is concluded that the absence of the increase in the parameter under study (ATP) after irradiation by the latter regimen indicates that preirradiation at a dose of 0.1 Gy inhibits the adequate development of an early response to irradiation with a dose of 4.9 Gy.
