title: The influence of tonsillectomy on cell-mediated immune response.
abstract: In order to ascertain the influence of a possible immunoregulatory effect of tonsils on the organism, phytohaemagglutinin (PHA) and concanavalin A (Con A) stimulation and the suppressor index in peripheral blood lymphocytes were determined in the pre-operative and postoperative course. Consistent statements on a possible effect of the tonsil can not be made from the results obtained.
