目前已有许多研究纤毛活动度的方法,包括电影摄像和光电记录。作者介绍一种测定气管支气管粘液纤毛活动度的新方法,即激光散射光光谱学。本实验还测定了气温及激光功率大小对纤毛运动的影响。体外实验选用新鲜的牛气管,体内实验用6头猪,激光通过纤支镜至下呼吸道,完成体内测定后杀死,并取出气管再进行体外实验。使用的激光为氩离 There are many ways to study the activity of cilia, including film camera and optical recording. The authors describe a new method for measuring the activity of the bronchial mucociliary in the trachea, which is laser light scattering spectroscopy. The experiment also measured the temperature and laser power on the size of the ciliary movement. In vitro experiments using fresh tracheotomy, in vivo experiment with 6 pigs, laser through the bronchoscopy to the lower respiratory tract, after completion of in vivo determination, killing, and remove the trachea and then in vitro experiments. The laser used is argon
