吸烟对健康的危害已成为一个社会问题,尤其是吸烟与心血管系统和与肺癌的关系更引起重视,而吸烟对呼吸系统其他方面的影响,以及吸烟与粉尘的联合作用则认识还不够。本文将就这方面的理论,结合我们的实践予以叙述。 1.对呼吸道清除功能的影响 呼吸道清除功能由两个方面完成:粘液纤毛上皮和肺泡巨噬细胞。 已知呼吸道上皮有八种细胞,即两种基底细胞、纤毛细胞、三种分泌细胞(杯状细胞,Clara细胞和浆细胞)、过渡细胞和有微绒毛的刷细胞。
The health hazards of smoking have become a social problem. In particular, the relationship between smoking and cardiovascular system and lung cancer has drawn more attention. The effects of smoking on other aspects of the respiratory system and the combined effects of smoking and dust are not recognized enough. This article will be on this theory, combined with our practice to be described. 1. Effects on Respiratory Tract Clearance Respiratory clearance is accomplished in two ways: mucociliary epithelium and alveolar macrophages. Eight types of cells are known in the respiratory epithelium, namely, basal cells, ciliated cells, three secreting cells (goblet cells, Clara cells and plasma cells), transitional cells, and brush cells with microvilli.
