用解充血剂及抗组织胺药来治疗中耳疾病的理论基础是它们能作用于充血肿胀的咽鼓管粘膜。咽鼓管内粘膜上的粘液毡的特性(如粘性及表面张力),近来已破强调为咽鼓管功能的重要因素,因为开放咽鼓管的力量必须冲开粘液层以分开管壁粘膜。为此探索一种有抑制分泌能力的药物是否能影响到咽鼓管功能似具有重要意义。本文研究的目的即为查明给予阿托品后,是否可引出一种可测得的咽鼓管功能改变。受试者为10名耳部健康者(20耳),无反复中耳病史及最近一个月内无上呼吸道感染史,经耳科显微镜检查鼓膜正常,鼓室图正常及听力在 The rationale for treating middle ear disease with decongestants and antihistamines is that they act on hyperemic and swollen eustachian tube mucosa. The properties of mucocut mucosa on the mucosa of the eustachian tube, such as stickiness and surface tension, have recently been highlighted as an important factor in eustachian tube function since the force of the open eustachian tube must be blown off the mucoid to separate the mucosa of the mucosa. To explore whether a suppression of secretion of drugs can affect the Eustachian tube function seems to be of great significance. The purpose of this study is to ascertain whether a measurable eustachian tube function change can be induced after administration of atropine. Subjects were 10 ears of healthy people (20 ears), no history of repeated middle ear and no history of upper respiratory tract infection in the most recent month. The eardrums were examined for normal eardrum, normal and tympanogram
