Abstract:
Objective To investigate the effect of hypertonic-hyperoncotic solution (HHS) on CD11b expression on the surface of human neutrophils which are stimulated by lipopolysaccharide (LPS) in vitro. Methods Neutrophils were isolated from fresh peripheral venous blood of healthy volunteers aged 20-4oyr find incubated with LPS 100 ng/ml al 37℃ in 5% CO2 incubator for 15, 30, 60min, 4, 12 or 24h. HHS was prepared with 10%NaCl and 10% hydroxyethyl starch. Neutrophils were incubated with 0.25% or 0.5%HHS for 10min, 1h or 4h. Some of the HHS treated neutrophils were further subjected to LPS stimulation for 30 mm. CDllb on the surface of neutrophils were measured by using immunofluorescence and flow cytometry. Results CD11b expression on neutrophils increased significantly after being exposed to LPS for 15min (P
