鼻粘液廓清时间(NMC)为检查鼻粘液纤毛功能的一种方法,并对鼻和上、下呼吸道疾病的诊断和预后有重要意义。早期采用直接观察沉积在鼻粘液上的着色物以及利用放射性粒子观察着色物等方法平测定NMC,但这些方法较复杂并需要昂贵、复杂的仪器没备。作者采用Andersen(1974)的糖精试验来测定NMC,此法简单,方便、经济、安全、易掌握。
Nasal mucus clearance time (NMC) is a method of examining the function of nasal mucocilia and is of great importance for the diagnosis and prognosis of nasal and upper and lower respiratory tract diseases. Early use of direct observation of sediment deposition in the nasal mucus and the use of radioactive particles to observe the color of the flat method of determination of NMC, but these methods are more complex and require expensive, complex instruments not prepared. The authors use the Andersen (1974) test of saccharin to determine NMC, this method is simple, convenient, economical, safe, easy to grasp.
