[In-vitro-investigation of immuno lymphocytolysis by influence of streptolysin O (author's transl)].

The cytolytic effect of Streptolysin O to leucocytes, T and B lymphocytes and granulocytes has been examined using an in vitro immuno lymphocytolytic test at 62 patients with different dermatological diseases. This test was established to be only about the immuno-cytolytic reaction of the T lymphocytes, and this process was bound to the present of complement. It is suggested that this method is suitable to in vitro study of the cellular immunity of patients with chronic infectious diseases.
