Abstract

A method is described for the simultaneous measurement of flow rate, mean transit time, and volume of the intestine during the transport of fluid through a segment of the small intestine of the dog. Using this method, the effect of metoclopramide on motility of the small bowel was assessed. The drug resulted in a decrease in transit time and volume in the test segment of bowel while the flow rate remained constant. This finding suggests that metoclopramide-stimulated contraction of intestinal smooth muscle.

摘要

描述了一种在液体通过狗小肠段运输过程中同时测量小肠流速、平均通过时间和容积的方法。使用该方法,评估了甲氧氯普胺对小肠运动的影响。该药物导致受试肠段的通过时间和容积减少,而流速保持恒定。这一发现表明甲氧氯普胺刺激了肠道平滑肌的收缩。
