纤毛动作驱动物质在各种上皮表面上的传输,包括纤毛粘液在气道及耳咽管和面神经管中的传输。纤毛动作也驱使第四脑室中液体的流动。为研究体外纤毛的动作,虽然已开发了几种方法,但目前还未获得能客观地检测并记录体内纤毛动作的方法。本文描述了光纤传导激光多普勒分光光度计测量纤毛在原位动作的研究情况,并证实了其有效性。分光光度计以高速摄像仪作为参照进行校准。在纤毛摆动频率从3～38Hz范围内测得的传递函
Ciliary motility drives the transport of substances across a variety of epithelial surfaces, including the transport of ciliary mucus in the airways and in the eustachian tube and facial nerve canal. Ciliary action also drives fluid flow in the fourth ventricle. Although several methods have been developed for the study of in vitro ciliary movements, no method for objectively detecting and recording ciliary movements in vivo has yet been obtained. This article describes the study of the fiber-optic laser Doppler spectrophotometer measuring cilia in situ motion and confirms its effectiveness. Spectrophotometer with high-speed camera as a reference for calibration. Transfer cords measured at ciliary swing frequency from 3 to 38 Hz
