[The role of genetically determined blood system markers in the development of humoral immunity disorders in those who worked in the cleanup of the aftermath of the accident at the Chernobyl Atomic Electric Power Station].

The immunoglobulins content was measured in blood serum of 233 individuals who took part in the elimination of effects of ChNPP breakdown. Distributive patterns of phenotypes, antigens and genes of HLA system depending on levels of Igs G, A and M have been studied. A positive association of some HLA antigens with concentration of immunoglobulins of certain isotypes was found out.
