急性坏死性胰腺炎肺损伤的发生机制研究
Journal of Hepatopancreatobiliary Surgery（2004）
Abstract
目的:研究急性坏死性胰腺炎(acute necrotizing pancreatitis,ANP)早期白细胞粘附强弱和肿瘤坏死因子(tumor necrosis factor,TNF)的变化及其与肺损伤的关系,探讨ANP肺损伤发生的可能机制.方法:5只家犬造模后在流室系统下观察白细胞与内皮细胞的粘附强弱,并测定血清内毒素水平以及外周血、支气管肺泡灌洗液(broncho-alveolar lavage fluid,BALF)TNF活性和肺损伤程度,与假手术组(4只)比较.结果:模型组犬可见明显肺损伤发生;白细胞粘附活性、血清内毒素水平、外周血及BALF中TNF活性明显升高.结论:白细胞粘附增强和TNF的过度分泌可能是ANP肺损伤发生的机制之一.
