Phagocytosis and the release of oxidative products generated by the respiratory burst have been studied in vitro under the influence of non-steroidal anti-inflammatory drugs: naproxen and ibuprofen, using.phagocytes of peripheral blood from healthy human donors. Phagocytosis wis monitored by flow cytometry in order to investigate the uptake of propvdium iodide-labelled bacteria (Staphylococcus aureus) by polymorphonuclear leucocytes. In addition, the phagocytic capacity and percentage of killed bacteria was measured in isolated neutrophils using the Pantazis & Kniker method. It was found that naproxen and ibuprofen affect the phagocytic function and hydrogen peroxide production in the examined granulocytes.
