[Determination of autoantibodies to antigens of thymic epithelial cells of clean up team workers and patients who survived acute radiation sickness at distant periods after irradiation].
A group of patients, suffering from sequelae of acute radiation sickness (ARS), and liquidators was studied 5 years after exposure to a complex of factors resulting from the Chernobyl A.P.S. disaster. Studied were: the antibody titres to antigens of the cytoplasm of thymus epithelial reticulum cells and to Hassall's corpuscles the levels of serum immunoglobulins M, G, A; and the content of serum alpha 1-thymosin. Patients with ARS sequelae and liquidators showed a high level and incidence of autoantibodies to antigens of cytoplasm of thymus epithelial reticulum cells and to Hassall's corpuscles. There were no significant differences between the antibody levels in the blood of patients with ARS sequelae and liquidators. The antibodies were found to belong to IgM class; there was a correlation between the serum IgM titres and the rate of the indirect immunofluorescence reaction with autoantibodies to antigens of the cytoplasm of the thymus epithelial reticulum cells. To identify autoantibodies cryostat sections of human and mouse, (CBA x C57BL/6) F1, thymus as well as the epithelial and stromal cell culture of mouse thymus can equally be used.
