[Cytotoxic action of immune lymphocytes on "adherent" cells (macrophages) of autologous system lymph nodes during delayed hypersensitivity].

A study was made in the autologous system of the cytotoxic action of immune lymphocytes on the "adherent" cells (macrophages) of the lymph nodes of guinea pigs in delayed hypersensitivity (DH) to the streptococcus antigens and tuberculoproteins. Death of a considerable number of the "adherent" cells in cultivation of a suspension of cells of the lymph nodes of animals sensitized with the culture of streptococcus or BCG in the presence of specific antigen (thermo-stable streptococcus fraction or tuberculin, respectively) alone. Detection of death of the "adherent" cells in the autologous system can be used as one of specific and sensitive tests in studying the DH.
