本文研究ATP对离体健康和感染的人呼吸粘膜的纤毛拍击频率(CBF)是否有兴奋作用。健康粘膜标本22个分别来自上颌窦(n=4)、蝶窦(n=9)、乳突腔(n=7)和中鼻甲(n=2),感染粘膜标本64个均来自慢性上颌窦炎者,以上粘膜标本用于研究1mg/mlATP对CBF的作用。另取5个感染上颌窦粘膜和1个正常蝶窦粘膜(共6个标本)用于研究10mg/mlATP对CBF的作用。粘膜标本制成5×5 mm,采用改良Mercke等的光电测定法测定CBF。将标本
This article investigates whether ATP is excited by the ciliary beat frequency (CBF) of ex vivo healthy and infected human respiratory mucosa. Twenty-two healthy mucosa specimens from the maxillary sinus (n = 4), sphenoid sinus (n = 9), mastoid cavity (n = 7) and middle turbinate (n = 2) Inflammation, the above mucosal specimens were used to study the effect of 1 mg / ml ATP on CBF. Another 5 infected maxillary sinus mucosa and a normal sphenoid mucosa (a total of 6 specimens) were used to study the effect of 10 mg / ml ATP on CBF. Mucosal specimens made of 5 × 5 mm, the use of improved Mercke and other photometric determination of CBF. Will the specimen
