摘要 目的 :观察黄芩苷对肺炎衣原体和大肠杆菌脂多糖诱导的E -选择素和一氧化氮的影响。方法 :在 2 4孔板培养人脐静内皮细胞 (ECV -3 0 4) ,待长成单层后加入肺炎衣原体 (CPN)为衣原体组 ,加入CPN和黄芩苷 0 48g/L为实验 1组 ,加入大肠杆菌脂多糖 (LPS)为LPS组 ,加入LPS和黄芩苷 0 48g/L为实验 2组 ,不加任何刺激物为正常组 ,每组设 4个复孔 ,培养 4d后 ,各组细胞消化后用流式细胞仪技术进行E -选择素检测 ,上清检测NO。结果 :血管内皮细胞经CPN刺激后E -选择素表达增加 ,NO分泌没有改变 ;血管内皮细胞经LPS刺激后E -选择素表达增加 ,NO分泌也增加 ;黄芩苷可降低LPS诱导的E -选择素和NO。结论 :CPN和大肠杆菌LPS对血管内皮细胞的刺激有不同的病理结果 ,中药黄芩苷有一定的抗炎作用。
