Characteristic of stochastic effects in participants of the Chernobyl nuclear accident consequences liquidation

870 patients - participants in diminishing of the consequences of the Chernobyl nuclear accident were clinical investigated, immunological, cytogenetic and oncological. The clinical investigation indicates the prevalence of large polymorphism of nervous, heart-vascular and gastric-intestinal system, which was accompanied by circulatory disorder of the vegetative nervous system. The aberrations of T-lymphocytes immunofenotype and tendency to T-/cell immunity insufficiency have been revealed with monoclonal antibodies to CD19+, CD3+, CD4+, CD8+, CDHLA DR+ and CD16+. Cytogenetic research of the lymphocyte cultures of periferal blood revealed the high level of genomic, chromosomal and chromatid type aberration. The structure of tumors has the appropriate profile, but not identical with the Chisinau populations, for the same period 1991-2009. (authors)
