早在1920年即采用蛙食管纤毛上皮作为研究纤毛传输功能的动物模型，此后许多学者认为不能照搬对温血动物的纤毛传输功能进行研究，因后者的纤毛上皮在离体试验中将迅速死亡。用简单方法测定家兔鼻粘膜纤毛上皮传输功能，将动物固定好，不用麻醉药物。向鼻内滴5滴混有活性碳粉末 As early as 1920, the use of frog esophageal epithelium as an animal model for studying the function of cilia transmission, since then many scholars believe that can not be copied on the warm-blooded animal ciliary transport function, because the latter’s ciliated epithelium in the in vitro test will die rapidly . A simple method was used to determine the nasal mucosal epithelial transmission in rabbits, and the animals were fixed without anesthetic. 5 drops of nasal mixed with activated carbon powder
