自1961年Myrwick等首次提出支气管肺泡灌洗(BAL)并用于研究肺泡巨噬细胞(PAM)以来,先后已有许多学者将BAL用于呼吸系疾病的临床诊断和治疗以及细支气管肺泡机能的病理生理的研究上。不过,迄今在进行BAL的方法或是从正常受试者中所取得的参考数值上都还未达到标准化。本文通过对15例健康受试者的BAL的研究,评价正常人BAL液中的 Since bronchial alveolar lavage (BAL) was first proposed by Myrwick et al in 1961 for the study of alveolar macrophages (PAMs), many scholars have used BAL for the clinical diagnosis and treatment of respiratory diseases and the pathology of bronchioloalveolar function Physiological research. However, to date, neither normalization of the BAL method nor reference values ​​taken from normal subjects has been achieved. In this paper, 15 healthy subjects BAL study to assess normal BAL fluid
