Effect of hyperbaric oxygenation on macrophage function in mice

Hyperbaric oxygenation (HBO) has an immunosuppressive effect. The possible mechanisms of this immunosuppressive effect were assessed by determining the production of interleukin-1 (IL-1), interleukin-6 (IL-6), and prostaglandin E2 (PGE2), as well as phagocytosis by splenic macrophages from HBO-treated mice. Although HBO treatment did not have any significant effect on IL-6 production and phagocytotic activity, a marked decrease in IL-1...
