In order to investigate the effect of baicalin on the expression of vascular endothelial cell adhesion molecules(E-selectin,ICAM-1,VCAM-1)induced by Haemophilus parasuis(HPS),porcine vascular endothelial cells were co-cultured with Haemophilus parasuis.The amount of E-selectin,ICAM-1 and VCAM-1 in cell culture medium was detected by ELISA.The mRNA expression levels of E-selectin,ICAM-1 and VCAM-1 in vascular endothelial cells were detected by Q-RT PCR.The results showed that after HPS infection with porcine vascular endothelial cells,the releas...
