尽管气道襞与肺泡的上皮细胞在形态结构方面存在着很大的差异,可是二者均为组成抵御吸入性异物的保护性屏障。Jones对人体的研究表明,吸烟者气道襞对TCDPTA的通透性增高,而当戒烟后这种改变即可恢复正常。无论是动物或人,吸烟都可使正常气道襞的上皮屏障产生可逆性漏渗的损伤。但是,目前尚不能 Although there is a large difference in the morphological structure of airway epithelium and alveolar epithelial cells, both are protective barriers that make up the composition of the foreign body against inhalation. Jones’s study of humans showed that the permeability of TCDPTA increased in smokers’ airways and returned to normal after quitting smoking. Whether animal or human, smoking can make the normal airway 襞 epithelial barrier produce reversible leakage damage. However, it is not yet possible
