The Intensity of Blood Lymphocyte Apoptosis in Chronically Exposed Individuals with Obligate Forms of Precancerous Conditions

We studied the apoptotic death of peripheral blood lymphocytes in individuals chronically exposed to radiation with a history of obligate forms of precancerous conditions. The study included 242 subjects chronically exposed to low-intensity radiation in the range of low and medium doses (mean dose of irradiation of the red bone marrow 555 ±39 mGy). Of these, 121 subjects had obligate forms of precancerous conditions. In irradiated individuals with obligate forms of precancers, a statistically significant increase in the frequency of apoptosis of peripheral blood lymphocytes at an early and late stages was revealed. Correlation analy sis revealed no dependence of the apoptotic death of peripheral blood lymphocytes on the dose of red bone marrow irradiation.
