[Lymphocyte subpopulations in non-Hodgkin's lymphoma during cytostatic therapy].

1. In non-Hodgkin-lymphomas with leucaemic form of the course a significant percental decrease of the number of T-lymphocytes and an also significant increase of the number of B-lymphocytes was to be proved. The increase of the B-lymphocytes concerned among others cells which carry the ME-receptor. 2. In non-Hodgkin-lymphomas with aleucaemic form of the course in decrease of the absolute number of lymphocytes a relative and absolute increase of the subpopulation of lymphocytes carrying the ME-receptor was provable. 3. In the course control of 7 patients with non-Hodgkin-lymphoma under polychemotherapy in 5 cases a discrepancy between the number of rosette-forming cells and the total number of lymphocytes appeared. 4. In the monotherapy of patients with CLL in favourable clinical development a percental increase of the T-cells is objectifiable after one year. A similar development was to be found in 3 patients after the first cycle with CVP.
