表面活性蛋白A（SP-A）和D（SP-D），与甘露糖粘合蛋白同属C型外源性凝集素，在调节外周气道许多防御功能方面起着重要作用。本文旨在通过测定健康吸烟者和不吸烟者支气管肺泡灌洗（BAL）液SPA与SPD的含量来阐明吸烟对特异表面活性蛋白的影响。病人和方法BAL液样品取自叨例健康
Survivin A (SP-A) and D (SP-D), both C-type exogenous lectins and mannose binding proteins, play an important role in regulating many defensive functions of peripheral airways. This article aims to clarify the effects of smoking on specific surface-active proteins by measuring the contents of SPA and SPD in bronchoalveolar lavage fluid (BAL) in both healthy smokers and non-smokers. Patients and Methods BAL fluid samples taken from 100 cases of health
