用普通支气管镜进行支气管肺泡灌洗,治疗严重的哮喘和肺泡蛋白沉淀等病,已有二十多年的历史。Mryvik等曾通过动物试验发现,支气管肺泡灌洗有助于各种肺部疾患的诊断,并可用于肺巨噬细胞的采集。目前,这种技术已成为肺细胞生物学研究的基础。过去,在肺部炎症和免疫系统疾患的病人中,肺内细胞的采集,是通过普通支气管镜或末端带有一气囊的导管嵌入支气管树的一、二级分枝,施行肺泡支 Bronchial lavage with ordinary bronchoscopy, treatment of severe asthma and pulmonary alveolar protein deposition and other diseases, has more than 20 years of history. Mryvik et al. Have found through animal experiments that bronchoalveolar lavage can help diagnose various lung diseases and can be used for the collection of lung macrophages. At present, this technology has become the basis of lung cell biology research. In the past, in patients with pulmonary inflammation and immune system disorders, the acquisition of intrapulmonary cells was carried out through the bronchoscope or at the distal end with a balloon catheter embedded in the primary and secondary branches of the bronchial tree, the alveolar branch
