摘　　要：本文应用高致病性禽流感病毒性肺炎(Highlypathogenicavianinfluenzaviralpneumonia,HPAIVP)小鼠模型,采用免疫组织化学染色方法,对实验组和对照组小鼠肺组织中ICAM-1及其受体的表达含量进行检测。研究发现:实验组小鼠肺组织中ICAM-1及其受体表达含量在攻毒后1d即开始升高,第4天达高峰。就攻毒剂量来说,以100LD50/50μL攻毒组小鼠肺组织中ICAM-1及其受体阳性表达量升高最明显。并通过ELASA方法进一步证实了这种变化。结果表明:ICAM-1及其受体在HPAIVP中呈现高表达,可能在其发病中发挥了重要作用。The intercellular adhension molecular-1 （ICAM-1 ） and it＇s its receptors in the mice＇s lungs of HPAIV and control mice pneumonia were detected by using immunohistochemistry staining after infected mice with Highly pathogenic avian influenza virus （HPAIV）. The expressive level of ICAM-1, and its receptors of CD1 lb and CD18 were first detected after 24 hours infection in bronchial alveolar epithelial cells, bronchopulmonary capillary endothelial cells, and iinfiltrativing lymphomonocyte and monocytes, and reached were the peaks 4 days after infection. The highest expression of ICAM-1 and its receptors were detected when infected with 100LD50/50μL HPAIV. The change was confirmed by the method of ELASA. Our results indicate that ICAM-1 and its receptors have the high expression level in HPAIVP pneumonia, and may play an important roles in the pathogenesis.
