[Radioadaptive response in lymphocytes of children living in territories polluted by radionuclides as a result of the accident at the Chernobyl power plant].

The radioadaptive response and antimutagenic action of lymphoblastoid interferon in the human blood lymphocytes of the children from polluted after Chernobyl accident Bryansk region were studied. Cells pretreated with tritiated thymidine with 2 Gy of gamma-rays at 20 h of culture after PHA-stimulation on seven of the ten donors result in lack of radioadaptive response. On testing some of them (4 donors) no protective adaptive response was found, others (3 donors) pretreated with tritiated thymidine gave sensibilization.

[The adaptive response in the lymphocytes of children from an area with an elevated background of ionizing radiation].

The ability to form the adaptive response in lymphocytes of 23 children, exposed to small radiation doses as the result of Chernobyl accident was studied by hydroxylapatite chromatography of cell lysates. No correlation was found between the ability to form adaptive response and received radiation dose.

[The formation of an adaptive response in children exposed to the effect of low doses of radiation as a result of the accident at the Chernobyl Atomic Electric Power Station].

The ability of lymphocytes to form an adaptive response in cells of the children which were exposed to small radiation doses during the Chernobyl accident was studied by hydroxyapatite chromatography of cell lysates. Ten children living in the area with high radiation level (Bryansk region) and seventeen children living in the area with natural radiation level (Bryansk region too) were examined. No difference in cell ability to form adaptive response was found in both children group.
