Abstract:
OBJECTIVETo investigate the effect of Panax notoginseng saponin (PNS) on procoagulant activity (PCA) and differentiation induction in NB4 cells.
METHODSAfter NB4 cells were treated with PNS, the recalcification time, PCA and TF-mRNA expression in NB4 cells were tested by RT-PCR. The inhibitory effect of PNS on NB4 cell proliferation was analysed by MTT method, NBT assay, cell morphological observation and flow cytometry.
RESULTS(1) PNS of all concentrations could significantly prolong the recalcification time and lower the PCA level in NB4 cells in time-concentration-dependent manner. Simultaneously it down-regulated the expression of TF-mRNA. (2) PNS could partially inhibit the NB4 cell proliferation. (3) PNS could raise the NBT reducing capability of NB4 cells (P < 0.05). And morphological examination showed the differentiating tendency of monocyte and macrophage.
CONCLUSIONPNS could reduce the procoagulant activity and TF-mRNA expression in NB4 cells, and partially induce the differentiation of NB4 cells, therefore, it is hopeful to be a new anti-coagulant agent.
