[Age-dependence of the cellular immune reaction in childhood. 2. Studies on children with acute lymphatic leukemias].

Results of studies made using the lymphocyte transformation test for leukemic children showed that an evaluation of cellular immunoreactions subsequent to the administration of szecific and nonspecific antigens as well as in the mixed culture is inadequate to recognize the characteristics of age-specific changes. A comparison of the rates of transformation in healthy children with those of leukemic children showed that age-specific characteristics are superseded by disease-specific changes.
