title: Serum lysozyme activity in some myeloproliferative diseases.
abstract: Serum lysozyme activity has been determined in patients suffering from myeloproliferative diseases, chronic myelogenous leukaemia (CML), acute myelogenous leukaemia (AML), chronic lymphatic leukaemia (CLL) and pancytopenia (P). Lysozyme activity was tested in undiluted and tenfold diluted sera. Increased lysozyme activity was found in patients with CML and CLI, whereas there was no change in patients with AML and P. Dilution of sera enhanced lysozyme activity. These data may indicate the presence of inhibitor in the sera tested. The diagnostic significance of the presented findings is discussed.
