ESR studies on oxygen consumption during the respiratory burst of human polymorphonuclear leukocytes.
Oxygen consumption during the respiratory burst of human polymorphonuclear leukocytes (PMN) stimulated with phorbol myristate acetate (PMA) was studied with spin probe oxymetry and using the transition metal ion CrOX (potassium trioxalatochromate) as a widening agent. The experimental results demonstrated that during the respiratory burst of PMN stimulated with PMA, oxygen consumption was found mainly in the intercellular medium but no change of oxygen concentration was found in the intracellular medium.
