人结肠被认为能松弛或收缩以接纳从上方来的内容物或加快其下行。扩张也是几种病理生理状态的特点,因此结肠容易扩张在疾病中具有重要意义。作者用电机械气压稳定装置记录了人结肠肌张力在生理性紊乱时的变化。材料和方法:14名年龄为18～43岁的健康男性作为研究对象。检测系统包括1个两端固定于导管的长10cm 的恒压气囊和导管内3条侧孔位置不同的注水测压微管。气囊内压通过自动注入或抽出空气维持在8～12mmHg 范围。气囊导管和测压管联接到同
The human colon is thought to relax or contract to accept content from above or to speed it down. Expansion is also a hallmark of several pathophysiological states, so colon expansion is of great importance in disease. The authors used electromechanical barostat to record changes in human colon muscle tone during physiological disorders. MATERIALS AND METHODS: Fourteen healthy men aged 18-43 years were enrolled. Detection system includes a fixed at both ends of the catheter length of 10cm constant pressure balloon catheter and the three side hole position of the water injection pressure microtubule. Airbag internal pressure by automatically injecting or withdrawing air to maintain the range of 8 ~ 12mmHg. The balloon catheter and piezometer are connected to the same
