To investigate the effect of tanshinone II A on the procoagulant activity (PCA) of human umbilical vein endothelial cells (HUVEC) induced by acute promyelocytic leukemia (APL) cell line NB4 cells. The HUVEC were incubated for 6, 12, and 24 hours in different tanshinone II A conditioned medias (Tan II A-NB4-24h-CM, Tan II A-NB4-72h-CM, Tan II A-NB4-120h-CM). Then the HUVEC were incubated for 6, 12, 24, and 72 hours with Tan II A-NB4-120h-CM and different concentrations of Tan II A (0, 0.25, 0.5, 1.0 microg/mL). The HUVEC lysates were obtained by three repeated freezing and thrawing. Their PCA were tested using the one stage clotting assay. The activity of tissue factor (TF : act) was tested using the chromogenic substrate assay. The control groups included 0.3 microg/mL ATRA, 0.01% DMSO and RPMI 1640. Tan II A-(72 h,120 h)-NB4-CM elevated PCA of HUVEC and six hours of incubation in the 120 h-NB4-CM had the greatest PCA. The PCA of HUVEC in the 1.0 microg/mL Tan II A-NB4-CM was the same as in the 0.3 microg/mL
