The larynx is the point of confluence of all tracheobronchial secretions and of the particles trapped within them. A study is made of laryngeal mucociliary transport using charcoal particles in 8 anesthetized rabbits and in 8 more during the immediate postmortem period. Most secretions were found to reach the posterior commissure, and were then swallowed. In the immediate postmortem rabbits, mucociliary transport velocity was 3.59 +/- 1.23 mm/min., with a transport time of 4.62 +/- 1.5 min. In the 8 rabbits anesthetized with droperidol, diazepam and thiobarbital, transport was found to be significantly slowed (p = 0.001).
喉是所有气管支气管分泌物及其中截留颗粒的汇聚点。对8只麻醉兔及另外8只刚死后的兔子，使用木炭颗粒进行了喉黏液纤毛运输的研究。发现大多数分泌物到达后联合处，然后被咽下。在刚死后的兔子中，黏液纤毛运输速度为3.59±1.23毫米/分钟，运输时间为4.62±1.5分钟。在用氟哌利多、地西泮和硫喷妥钠麻醉的8只兔子中，发现运输明显减慢（p = 0.001）。
