[Opsonic cooperation in the neutrophil phagocytosis system in acute myeloblastic leukemia].

Investigation of opsonic activity of the serum (OAS) and indices of neutrophil phagocytosis in 35 patients with acute myeloblastic leucosis (AML) and 20 healthy subjects indicates that reduction of OAS in AML results in disturbances of the processes of reception and absorption of microorganisms by granulocytes while insufficient activation of oxygen-dependent metabolism favours disorders of bactericidal activity of neutrophils.
