[Changes in immunocompetent cells under exposure to ionizing radiation].

The modern knowledge concerning radiosensitivity of immunocompetent cells and intracellular changes is discussed in the review. A conclusion is made about the results of irradiation which are not easy to interpret. They depend on the cell type, functional state, and some other factors and conditions.

[Immune system status under effect of low levels of ionizing radiation:studies within the 10 kilometer zone of accident at Chernobyl nuclear plant].

A study was made of the influence of high radiation contamination within the ten-kilometer zone of Chernobyl disaster on the structure and function of the immune system of (DBA x C57B1)F1 and DBA mice. The cumulative radiation doses with respect to gamma-radiation, were 0.024, 0.

[A possible role of neuroimmunoendocrine interactions and development of post-irradiation pathology].

On the basis of the literature a postulate is proposed that the immune system contributes to regulating the intensity and direction of endocrine and nervous system functions in normal conditions and after the effect of ionizing radiation. The role of neuroimmunoendocrine interactions and their impairment in the realization of stochastic and nonstochastic sequelae of irradiation at various levels of radiation affecting the organism under normal conditions and in a combination with other unfavourable factors.
