Abstract:
AIM: To explore the effect of recombined sICAM-1 on the adhesion of leukocyte to pulmonary microvascular endothelial cell. METHODS: Primary cultured rat pulmonary microvascular endothelial cells were used in this experiment. Leukocyte was labeled with 99 Tm-HMPAO.The effects of different dose of sICAM-1, CA7 and dimeric form of sICAM-1 (sICAM-1?CA7)were tested separately in cell adhesion .RESULTS: sICAM-1 and CA7 could not inhibit cell adhesion even at the concentration of 100 mg/L,while sICAM-1?CA7 at concentrations of 20 mg/L and 40 mg/L could inhibit 42% and 50% of cell adhesion respectively ( P
