Results and discussion

Any other information on results incl. tables

The ability of macrophages obtained from the peritoneal cavity of mice to phagocyte Staphylococcus aureus  was inhibited by 0.5% MMA in the culture medium.  Human heparinised blood was incubated with concentrations of 0.5%, 1.25%, and 2.5% MMA for 15 min.  The number of leucocytes was reduced at a concentration of 2.5% MMA, no viable cells
were detected by the trypane blue method, at 1.25% the number of viable leucocytes was reduced to about 50%.  Phagocytic polymorphonuclear neutrophils were damaged to a greater extent than lymphocytes.  Erythrocytes and platelets
were completely lysed at 2.5% MMA.
