吸烟可以促进呼吸道疾病已被大量实验研究证实。作者们复习了以往有关文献后指出,长期吸烟可使气管粘膜的纤毛停止活动,粘膜表面可附着一层似柏油样的物质;吸烟与增加上呼吸道癌发病率的关系亦有大量研究报告。作者们给家兔吸入带滤嘴的埃及香烟,并对声带粘膜在电子显微镜下做超微结构的观察。实验分二组,即试验组和对照组。试验组的家兔每天暴露在香烟烟雾中2次,每次10分钟,共3个月。对照组的动物,除不吸人香烟烟雾外,其他生活和饮食条件同试验组。试验家兔在最后一次香烟烟雾中暴露24小时后杀死,切除声带组织,进行处理后,在电子显微镜下观察。所见如下:声带上皮有程度不同的增生肥厚,细胞层次紊
Smoking can promote respiratory disease has been confirmed by a large number of experimental studies. After reviewing previous literature, the authors pointed out that long-term smoking can stop tracheal mucosal cilia, the mucosal surface can be attached to a layer of tarry-like substances; smoking and increased the incidence of upper respiratory tract cancer there are a lot of research reports. The authors inhaled rabbits with filtered Egyptian cigarettes and observed the ultrastructure of the vocal cord mucosa under an electron microscope. The experiment divided into two groups, namely test group and control group. The rabbits in the experimental group were exposed to cigarette smoke twice a day for 10 minutes each for 3 months. Animals in the control group, except smoking cigarettes, other living and eating conditions with the experimental group. The rabbits were killed 24 hours after the last cigarette smoke exposure, the vocal cords were removed, processed, and observed under an electron microscope. See the following: Vocal cord epithelial hypertrophy with varying degrees of hypertrophy, cell level disorder
