[Behavior of thymus-arised lymphatic cells in the peripheral blood in acute leukoses]
On the basis of their ability of the spontaneous formation of rosettes by unsensibilised sheep erythrocytes the proportion of thymic lymphatic cells in 7 acute and 3 chronic lymphatic leukaemias was determined. Further observations on the content of T-cells in the peripheral blood were performed in leukoses, whereby the remission was begun with prednisone and cytostatics, under the immune stimulation with BCG during the remission and in 3 children with lymphogranulomatosis before and after splenectomy. The results of the acute stage of leucosis refer to the possibility of a prognostic evidence with the subclassification of the ALL. The T-cell-leukaemias revealed a particularly unfavourable course of disease. Cytochemically they were acute lymphatic leukaemias of undifferentiated type. In leucoses with smaller proportion of T-cells the blasts above all revealed a granular PAS-reaction.
