title: [Isoenzymes of acid phosphatase in blood cells of normal subjects and patients with leukemia (author's transl)].
abstract: The activities of acid phosphatases (AP) were measured in leukocytes from patients with chronic myelocytic leukemia (CML), macrophages, granulocytes, in the fractionated mononuclear cells of patients with CML and with hairy-cell-leukemia (HCL) and in the cells from patients with acute leukemia (AL). The lowest activities were found in lymphocytes of normal subjects and of patients with chronic lymphatic leukemia (CLL) and in thrombocytes. Isoenzyme (IsE) 1 was characteristic for thymocytes, IsE 2 for granulocytes, IsE 3 for pathologic blast-cells, lymphocytes and thrombocytes, IsE 4 for macrophages, IsE 5 with components a and b for the mononuclear fraction of patients with HCL. In addition IsE 5 was detected in lymphocytes, macrophages and CLL-cells. In 4 patients with HCL the relative percentage of IsE-5-fraction was slightly greater than the percentage of tartrate resistant cells. In two patients with questionable HCL well marked IsE-5-fractions were recognized but no tartrate resistant cells. In one patient with HCL a relatively high percentage of tartrate resistant hairy-cells and in comparison an inadaquate low IsE-5-fraction was found. These different relations were explained with the more sensitive method of gelelectrophoresis and different affinity of substrates to AP.
