摘要
目的:探讨人巨细胞病毒(HCMV)对人脐静脉内皮细胞(HUVEC304)产生可溶性细胞间黏附分子-1(sICAM-1)的影响及银杏黄酮甙的干预作用。方法:采用ELISA法分析细胞培养上清中sICAM-1的含量,对HCMV感染离体培养的HUVEC304及银杏黄酮甙作用后的情况进行观察和分析。本实验随机分为4组,分别为对照组,银杏黄酮甙组,HCMV感染组,HCMV感染+银杏黄酮甙组。结果:实验发现HCMV感染HUVEC304,在24 h后,可以强烈增强HUVEC304产生sICAM-1。对照组为(0.385±0.018)ng/m l,加入HCMV后为(1.064±0.037)ng/m l(P<0.05)。用10-2mol/L银杏黄酮甙后,被感染细胞产生的sICAM-1为(0.537±0.024)ng/m l,较感染组显著降低(P<0.05)。结论:HCMV感染HUVEC304后,强烈刺激细胞产生sICAM-1。银杏黄酮甙可减弱HCMV感染细胞产生sI-CAM-1,因而可能对防治动脉粥样硬化有一定的作用。
AIM: To investigate the effect of ginkgo flavone glycoside on HCMV-induced release of soluble intercellular adhesion molecule-1 (sICAM-1) of cultured human umbilical vein endothelial ( HUVEC304 ) . METHODS : sICAM-1 was assayed with ELISA kit. The cultured HUVEC304 was randomly divided into four groups: the control group, the ginkgo flavone glycoside group, the HCMV group and the ginkgo flavone glycoside + HCMV group. RESULTS :HCMV strongly induced sICAM-1 production in HUVEC304( (0.385±0.018)ng/ml vs (1.064±0.037)ng/ml (P〈0.05)). Ginkgo flavone glycoside inhibited the effect of HCMV. CONCLUSION: HCMV strongly induces sICAM-1 production in HUVEC304. The inhibitive effect of ginkgo flavone glycosidein on HCMV may possess the preventive and therapeutic effects on AS.
