鼻腔粘膜機能と副鼻洞粘膜機能との関係

　生物界に於ける線毛の存在は，系統発生的並びに個体発生的に極めて早くより存している事が知られている。即ち，水生の単細胞動物，例えばザウリムシにては極めて多数の線毛を有して居るが，下等動物に於ける線毛の存在意義は主に，運動器官であり，又食物摂取器官である。高等動物に於ては線毛上皮は気道，性器等にも認められるが，その作用の本態は以上と異り運搬能力と考えられている。

　人体に於ける線毛の観察も既に古くよりあるが，形態的，静的な観察が多く，その動的な面に於ける観察は漸く近年になつてからである。

Goto and Kinugawa made studies on ciliary movements inherent to the mucous membranes of the nasal cavity and the maxillary sinus to find a possible relation between the two. With 82 patients comprising 164 nares as clinical ma-terial for study zinc oxide powder was insuf-flated into the nasal cavity. And thereafter, every 10 minutes for the period of 30 minutes, the nasal cavity particularly the surface of the septum and the middle and inferior turbinates was inspected for the manner in which the pow-der may be eliminated from these structures. With the maxillary sinus 15% molyodol (iodized oil) was instilled into it and the mode with which this agent to be dispelled was noted. From these observations the authors concluded that the ciliary movements of the nasal mucous membranes do not necessarily coincide with that of the maxillary sinus. And clinically to assume a diagnosis of sinus condition based upon the state in which nasal mucous mem-branes may present themselves appeared to be premature and necessitating a further study on the subject.
