[The importance of studying the acid phosphatase of the blood serum and bone marrow lymphoblasts and polymorphonuclear neutrophils in the prognosis of the course of acute lymphoblastic leukemia].

The activity of serum acid phosphatase (AP), bone marrow lymphoblasts and polymorphonuclear neutrophils was studied in 45 ALL patients. Cytochemical coefficients (CCC) and the percentage of positively reacting bone marrow cells were determined. All the patients received programmed polychemotherapy.

[Acid phosphatase of leukocytes in patients with diffuse toxic goiter in evaluating the stage of the disease].

Acid phosphatase (AP) of lymphocytes and neutrophils was examined cytochemically in 23 patients with associated diffuse toxic goiter (DTG) and thyrotoxicosis during thiamazol treatment, in 20 persons with a DTG remission, and in 5 patients with postradiation and postoperative hypothyroses. AP activity with multiple-granule distribution of the enzyme was high in the majority of the patients with thyrotoxicosis, decreasing with thiamazol treatment. Thyrotoxicosis recurred in 4 out of 11 patients whose lymphocytes had an increased amount of AP during a DTG remission.
