...H. Ohta; Y. Matsuda Muramidase, acid phosphatase and nonspecific esterase were investigated in mononuclear cells of skin window exudate in normal persons and patients with various forms of leukemia. While acid phosphatase and nonspecific esterase gradually increased, muramidase activity was reduced...

...L.A. Rozenszajn; Ben David; Bar Sela The phenomenon of giant anomalous lysosome formation in human Chediak-Higashi syndrome leukocytes was analyzed. Ultrastructure findings combined with cytochemical procedures for visualizing acid phosphatase and peroxidase activity showed giant anomalous granules...

...G.A. Pangalis; W. Kuhl; S.R. Waldman; E. Beutler B and T lymphocytes were separated by means of the spontaneous sheep red blood cell rosette formation technique from 3 normal donors. The following acid hydrolases were biochemically determined on separated B and T lymphocytes: acid phosphatase, β...

...Helmut Wehinger; Walter Möbius Lymphoblasts from ten patients with ALL or stage IV malignant lymphoma were studied cytochemically and investigated for rosette-forming capacity with sheep red blood cells (SRBC) as a T cell surface marker. SRBC binding capacity and acid phosphatase or β -lucuronidase...

...S. Woessner; R. Lafuente; J. Capdevila; S. Sans-Sabrafen The normal isoenzymatic pattern of leucocytic acid-phosphatase based on the study of 150 haematologically normal individuals is reported. The different pathologic patterns of the leucocytic acid-phosphatase isoenzymes occurring in non...

...W. Sutowicz; Z. Komorowska; Z. Hanicki; T. Cichocki; O. Smoleński It was found that neutrophils in untreated uraemic patients as well as in subjects on regular dialysis treatment displayed higher activity of acid phosphatase, alkaline phosphatase and peroxidase. Spontaneous reduction of nitro blue...

...Michele Tortarolo; Nicola Cantore; Mario Grande; Giuseppe Buonanno; Franco Dammacco Plasma cell acid phosphatase has been studied in 51 patients, 30 of whom were affected with multiple myeloma (MM) and 21 with nonmyelomatous monoclonal immunoglobulinemias (NMMI). Scoring of results displayed...

... with acid alpha-naphthyl acetate esterase (ANAE) and acid phosphatase (AP) cytochemical data. The vast majority of T-ALL cells proved to be ANAE-negative (30/31) and AP-positive (29/31). Null-ALL was always AP-negative (12/12), the ANAE reaction was sometimes positive (4/12). In common ALL, findings ranged...

...S. Woessner; R. Lafuente; L. Florensa; J. Sans-Sabrafen We have studied the amount and intracellular distribution of erythroblastic alkaline and acid phosphatase, nonspecific esterase, and N-acetyl- β -glucosaminidase in 50 patients with acquired dyserythropoiesis. 19 morphologically normal bone...

... of the vacuoles but not in most vacuoles. Even when Ig was included in the vacuoles, only the contents of the vacuoles were positive for Ig but their demarcating membrane was negative for Ig. In contrast, electron microscopic studies of acid phosphatase activity revealed the presence of its activity in all...
