Effect of Xingnaojing Injection on PMN Adhering to BMVEC in Vitro

OBJECTIVE:To investigate the anti-adherence effect and its mechanism of Xingnaojing(XNJ)injecˉtion.METHODS:In mixed culture of rabbit’s PMN and brain microvascular endothelial cell(BMVEC),the effects of XNJ on LPS-induced PMN-BMVEC adhesion and the changes of PAF and NO levels were observed.RESULTS:XNJ could obviously decrease the PMN-BMVEC adhesion rate and the levels of NO and PAF in culture medium.CONCLUSION:XNJ can inhibit adhesion of PMN to BMVEC and release of some inflammatory media.The decrease of some inflammatory media may related to the reduction of adhesion.
