Analysis of the eustachian tubal cell secretion in the cell culture and its clinical aspects

定量评价大鼠咽鼓管功能，然后通过改变姿势和饥饿降低咽鼓管的开闭压。本研究通过对输卵管上皮细胞和腺细胞进行原代培养，探讨输卵管粘膜分泌物对输卵管功能的影响。临床证明，鼻内滴注生理盐水对咽鼓管扩张有效。其机制被认为是机械性输卵管关闭和可能的输卵管分泌调节。

The eustachian tube function was evaluated quantitatively in the rat, and then tubal opening and closing pressure was decreased by postural change and starvation. Primary cell culture of tubal epithelial and gland cells was attempted to examine the effect of the tubal mucosal secretion to the tubal function. Clinically, nasal instillation of saline was shown to be effective to patulous eustachian tube. Its mechanism is considered to be mechanical tubal closure and possible modulation of tubal secretion.
