Abstract
- The velocity and pattern of movement of lymph in the thoracic duct of anaesthetized and conscious dogs has been studied by observing the movement of droplets of ultrafluid lipiodol in the duct.2. The velocity of flow when anaesthetized varied from 0.1-2.0 cm/sec, to 5.0 cm/sec when conscious.3. The pattern of flow was affected by respiration and the cardiac cycle. Most movement occurred at the end of inspiration.4. The duct of five autopsy preparations was perfused with saline to assess the volume and velocity of flow produced by the level of pressure gradients previously observed in the duct. These studies show that the small gradients (2-5 mmHg) observed during life are more than sufficient to produce the normal volume and velocity of flow measured. The mean resistance of the duct was 0.5 mmHg/ml. min.
摘要
通过观察超流体碘油滴在麻醉和清醒犬胸导管中的移动情况，对胸导管中淋巴的流速和流动模式进行了研究。
麻醉时的流速为0.1 - 2.0厘米/秒，清醒时为5.0厘米/秒。
流动模式受呼吸和心动周期影响。大多数移动发生在吸气末。
对五份尸检标本的导管灌注生理盐水，以评估由先前在导管中观察到的压力梯度水平所产生的流量和流速。这些研究表明，在活体中观察到的小梯度（2 - 5毫米汞柱）足以产生所测量的正常流量和流速。导管的平均阻力为0.5毫米汞柱/毫升·分钟。
