ＴＮＦα是一种重要的炎症介质。血管内皮细胞是ＴＮＦα作用的靶细胞之一。由ＴＮＦα引起的血管内皮细胞损伤在很多炎症性疾病的发病中具有重要意义。本工作主要研究不同浓度的ｒｈＴＮＦα（简称ＴＮＦ）引起大血管内皮细胞（人脐静脉内皮细胞）和微血管内皮细胞（大鼠肺微
TNFα is an important inflammatory mediator. Vascular endothelial cells are one of the target cells for TNFα. Vascular endothelial cell injury caused by TNFα is of great importance in the pathogenesis of many inflammatory diseases. This work mainly studies different concentrations of rhTNFα (referred to as TNF) caused by large vascular endothelial cells (human umbilical vein endothelial cells) and microvascular endothelial cells (rat lung micro
