肿瘤坏死因子(tumor necrosis fator,TNF)是与感染密切相关的细胞因子,是免疫反应和炎症反应中的重要介质。它通过增加肺血管通透性和降低肺顺应性参与肺部的炎症反应。透明质酸(hyaluronic acid,HA)是细胞外基质的重要成份,与TNF共同参与肺部炎症反应过程,本文采用放射免疫分析法(RIA)检测35例重症肺感染患者血清TNF与AH水平,并
Tumor necrosis factor (TNF), a cytokine closely related to infection, is an important mediator in immune response and inflammatory reaction. It participates in inflammation of the lungs by increasing pulmonary vascular permeability and decreasing lung compliance. Hyaluronic acid (HA) is an important component of extracellular matrix and participates in inflammatory reaction of lung with TNF. Serum TNF and AH levels in 35 patients with severe pulmonary infection were detected by radioimmunoassay (RIA)
