In an attempt to clarify the effect of middle ear effusions (MEEs) on ciliary activity, the ciliary beat frequency (CBF) of nasal epithelium from normal subjects was determined following incubation in Hanks' solution containing effusions from pediatric otitis media with effusion. Both serous and mucoid types of effusions increased CBF 15 min after incubation. The mucoid type of effusion was then found to decrease CBF 6 h after incubation. Since the pH and osmotic pressure of the solution containing the effusions were within the physiological ranges for normal ciliary beating, our findings show that MEEs can influence CBF in vitro.
为了阐明中耳积液（MEEs）对纤毛活动的影响，在含有小儿渗出性中耳炎积液的汉克斯溶液中孵育后，测定了正常受试者鼻上皮的纤毛摆动频率（CBF）。浆液性和黏液性积液在孵育15分钟后均增加了CBF。随后发现黏液性积液在孵育6小时后降低了CBF。由于含有积液的溶液的pH值和渗透压在正常纤毛摆动的生理范围内，我们的研究结果表明MEEs在体外可影响CBF。
