在麻醉兔子的完整输卵管中研究了活体上染色的卵丘卵团的壶腹运输，这些兔子的腹部被打开进行观察。观察正常运输后，壶腹部的肌肉活动受到乙酰丙嗪（一种麻醉前镇静剂）的药理抑制。由于肌肉收缩受阻，卵子运输仍在继续，但方式发生了显着改变。在壶腹的最后 2/3，运动从快速的来回运动变为缓慢均匀的子宫前运动，这归因于纤毛活动。当平滑肌受到抑制时，运输的净速度没有变化，这表明肌肉收缩至少是不必要的，而且对于兔子壶腹卵的运输可能是无效的。
Ampullary transport of supravitally stained cumulus egg masses was studied in intact oviducts of anesthetized rabbits whose abdomens were opened for observation. Following observations of normal transport, muscular activity of the ampulla was inhibited pharmacologically with Acepromazine, a preanesthetic tranquilizer. With muscle contractions blocked, egg transport continued but in a dramatically altered fashion; in the final 2/3 of the ampulla the motion changed from rapid to-and-fro movements to a slow uniform prouterine movement which was attributed to ciliary activity. The net velocity of transport did not change when the smooth muscle was inhibited, indicating that muscle contractions are at least unnecessary and perhaps ineffective for ampullary egg transport in the rabbit.
