[Effect of prodigiozan on the antibody-dependent cytotoxicity of neutrophils in chronic myeloid leukemia].

Decreased levels of neutrophils, Fc- and C3-expressing receptors, oxygen-dependent metabolism as well as antibody-dependent cytotoxicity of these cells to target cells were identified in advanced chronic myeloid leukemia, particularly, in blast crisis. Treatment with cytostatic agents resulted in further decrease in said parameters. However, treatment with prodigiozan was followed by improvement in cell functioning.
