中文摘要:
      目的:观察慢性阻塞性肺疾病(COPD)大鼠肺组织中ICAM-1及MMP-9的表达及红霉素的干预作用。方法:复制COPD 大 鼠模型,并用红霉素干预,收集支气管肺泡灌洗液行细胞学计数和分类检查;采用HE染色观察病理形态变化;免疫组化法检测大 鼠支气管肺组织ICAM-1、MMP-9 的表达。结果:与模型组比较,干预组支气管肺组织中ICAM-1、MMP-9 表达显著降低;模型组 中ICAM-1、MMP-9 的表达与BALF中白细胞总数及中性粒细胞数成正相关;ICAM-1 与MMP-9 的表达成正相关。结论:COPD 大鼠肺组织中的ICAM-1、MMP-9表达明显升高,可能与COPD 的发病机制有关;红霉素可降低ICAM-1、MMP-9 的表达,可能是 红霉素在COPD中抗炎症反应的作用机制之一。
英文摘要:
      Objective: To explore the role of ICAM-1 and MMP-9 in the pathogenesis of COPD, and to study the effects of erythromycin( EM)on lung ICAM-1 and MMP-9 expression in vivo experiment of COPD rats. Methods: We established COPD rat models and use Erythromycin to interven. BALF were collected to count the total and differential cell counts. The pathological changes were observed. The expressions of ICAM-1 and MMP-9 were detected by immunohistochemistry. Results: Compared to the COPD group, the expression of ICAM-1 and MMP-9 in control group were significantly dcreased; Correlations analyze in COPD group: Both positive correlations were demonstrated in the expression of ICAM-1 and MMP-9 with WBC counts, PMN counts, PMN counts; Positive correlations were demonstrated between the expression of ICAM-1 and MMP-9; Conclusions: The difference of expression of ICAM-1 and MMP-9 between COPD group and control group have statistical significance, which indicate that ICAM-1 and MMP-9 may play important role in the formation of COPD; EM may play a certain protective role in the treatment of COPD through decreasing the expression of ICAM-1 and MMP-9 and weakening the inflammatory response.
