Role of neutrophils on diagnosis of the severity in lung dysfunction following hemorrhagic shock

中性粒细胞在诊断失血性休克后肺功能障碍严重程度中的作用

基本信息

项目摘要

We examined the role of neutrophils on diagnosis of the severity in lung dysfunction by grading four groups of severity of bleeding in rats. As the amount of bleeding increased, the expression of mRNA for TNF-α and IL-1β in the lung tissue and the pulmonary serum levels of both cytokines increased progressively up to 5 hours, and the frequency of activated neutrophils increased likewise. The lung dysfunction indices serum lactic dehydrogenase-3 isozyme (LDH-3), partial pressure of arterial oxygen (PaO_2) and alveolar-arterial oxygen tension difference (A-aDO_2) in blood deteriorated as the amount of bleeding increased. The frequency of activated neutrophils in the lung correlated well with the LDH-3 level 5 hours after hemorrhagic shock. The present results demonstrate that the increases of the recruitment of neutrophils into the lung activated by proinflammatory cytokines are quantitatively related to progression of lung dysfunction following hemorrhagic shock.
我们通过对四组大鼠的出血严重程度进行分级,研究了中性粒细胞在诊断肺功能障碍严重程度中的作用。随着出血量的增加,肺组织中 TNF-α 和 IL-1β 的 mRNA 表达以及肺功能的变化。肺血清中两种细胞因子的水平逐渐升高,直至5小时,活化的中性粒细胞的频率也同样升高,肺功能障碍指标血清乳酸脱氢酶3同工酶(LDH-3)、动脉分压。随着失血量的增加,血液中的氧分压(PaO_2)和肺泡-动脉氧张力差(A-aDO_2)恶化。失血性休克后5小时,肺中活化的中性粒细胞的频率与LDH-3水平密切相关。结果表明,促炎细胞因子激活的中性粒细胞募集到肺部的增加与失血性休克后肺功能障碍的进展定量相关。
