摘要

Hidden chromosome instability in 53 persons who underwent radiation exposure of different intensity was evaluated with the use of the modified G_2-bleomycin sensitivity assay. A wide interindividual variability in the frequency of chromosome aberrations and absence of positive correlation between the background and bleomycin-induced cytogenetic effects in all examined individuals were found. The maximal number (57.9%) of individuals hypersensitive to the testing mutagenic activity of bleomycin was found in the group of reconvalescents of acute radiation syndrome. In the other groups, the frequency of individuals with hidden chromosome instability was practically the same and did not exceed 33.3%. The results confirmed the reality of the radiation-induced modification of genetically determined susceptibility of human somatic cell chromosomes to mutagenic stress; such susceptibility depends on the intensity and character of irradiation.
