评价鼻腔粘膜上皮细胞纤毛功能，广泛采用的指标为纤毛摆动频率（CBF）。研究纤毛的功能最好在细胞培养的条件下进行以排除非上皮细胞、细菌污染等因素的影响，且持续时间较长，但单层细胞培养时纤毛减少以至消失，采用悬浮法可解决这一问题。病例为10例反复上呼吸道感染的患者 Evaluation of nasal mucosal epithelial cell cilia function, a widely used indicator of ciliary beat frequency (CBF). It is best to study the function of cilia in cell culture conditions to exclude the impact of non-epithelial cells, bacterial contamination and other factors, and the longer duration, but the monolayer cell culture to reduce or disappear when the cilia, the suspension method can solve this problem.
