Abstract
Some essential functions of polymorphonuclear neutrophils (PMN) were evaluated in 30 patients splenectomized because of rupture of the spleen. These cells revealed normal random migration, adherence, unstimulated O2- and H2O2 production. Phagocytosis of viable staphylococci was higher than in controls, whereas chemotaxis, bactericidal capacity, aggregation and stimulated O2- and H2O2 production were significantly impaired. PMN from splenectomized patients manifested also the decreased intracellular myeloperoxidase activity. The percentage of cells with receptor for Fc IgG in peripheral blood was markedly decreased. Plasma of these patients induced increased adherence of autologous as well as control neutrophils. The possible mechanisms leading to the observed events are discussed.
