STUDIES ON THE EFFECT OF CERTAIN MACROMOLECULAR SUBSTANCES ON THE RESPIRATORY ACTIVITY OF THE LEUCOCYTES OF PERIPHERAL BLOOD.
The oxygen, uptake of lightly heparinized human blood was found to increase markedly upon the addition of bacterial endotoxins, soluble antigen-antibody complexes, or polystyrene latex particles. The effect apparently reflects a transitory stimulation of respiratory activity of the blood leucocytes. The effect did not occur in the presence of anticoagulant amounts of citrate or ethylenediaminetetraacetate, was inhibited by iodoacetate and fluoride ions, and may be related to the energy-yielding processes involved in histamine release or phagocytosis.
