Decreased chemotactic and random migration of leukocytes during Intralipid infusion.

The soybean oil emulsion Intralipid was given intravenously to 12 healthy subjects for 2 hr. During the infusion an impairment of the chemotactic and random migration of leukocytes was noted. It was correlated to the dose given and to the degree of hypertriglyceridemia induced. Migration was fully restituted 22 hr after the infusion. Also when added in vitro Intralipid caused an impairment of leukocyte motility that followed a dose response pattern.
