title: The effect of intralipid on mononuclear and polymorphonuclear phagocytes.
abstract: Eight healthy subjects were given Intralipid, a soybean oil emulsion, 20% intravenously for 2 h. During the infusion a significant increase in the nitroblue tetrazolium-reduction of blood monocytes was noted. Preincubation of monocytes in vitro with Intralipid (20 to 100 mg/ml) for 30 min was found to increase the ability of the cells to migrate chemotactically and to phagocytize yeast particles. On the contrary, when neutrophilic granulocytes were preincubated with Intralipid in the same concentrations for 30 min. their nitroblue-tetrazolium-reduction, chemotactic and spontaneous locomotion, as well as their ingestion of yeast particles was depressed.
