The distribution of euchrysine-binding grains of the peripheral and bone marrow stem cells in different types of acute leukemia.

The distribution of the fluorescent euchrysine-binding grains in the peripheral and bonmarrow stem cells was estimated in 28 cases of different types of acute leukemia verified according to Lòffler's cytochemical classification. The relationship between the pattern of fluorescent euchrysine-binding grains of human stem cells and the cytochemical type of acute leukemias has been established. Consequently, the authors suggest that the euchrysine-binding grains pattern of human stem cells may have a diagnostic value in distinguishing between various types of acute leukemia.

[Usefulness of beta-glucuronidase activity determination in the differential diagnosis of acute leukemia].

In 95 cases of acute leukemias the cytochemical type was determined according to Löffler's classification and the activity of beta-glucuronidase was determined in blast cells. In the light of these investigations it was demonstrated that determination of the activity of this enzyme may be useful only in the differential diagnosis and classification of certain cases of acute lymphoblastic or undifferentiated-cell leukaemias.

[Lysosomes of blast cells in various cytochemical types of acute leukemia].

In 25 cases cytochemical types of acute leukemia were determined using the classification of Loeffler. Three cytochemical methods used were: p.a.S.-glycogen content, pox-peroxidase activity, and esterase activity determinatione. At the same time selective identification of lysosomes in perypheral blood blast cells was done using vital euchrisine staining and fluorescence microscopy. A correlation was observed between the cytochemical types of acute leukaemia and the lysosomal pattern. The fluorescence method of the identification of lysosomes is suggested for diagnosis of acute leukaemia.
