The external diameter of the artery predominantly supplying the gracilis muscle was recorded by contact inductive transducer in anesthetized dogs. Blood flow from this artery was directed via an A--V shunt straight into the vein. An increase in blood flow from 4.9+/-0.7 to 45.5+/-6.6 ml/min with a latency of 11.3+/-1.3 sec evoked an increase of 12.6+/-1.3% in the diameter of this artery. Dilatation was independent of whether intravascular pressure at the recording site increased, decreased, or remained unchanged. The smooth arterial muscles seem to be able to "sense" the deformation and, as a result their arteries can automatically change their lumen in response to changes in blood flow velocity.
用接触式电感换能器记录了麻醉犬中主要供应股薄肌的动脉的外径。来自该动脉的血流通过动静脉分流直接导入静脉。血流从4.9±0.7毫升/分钟增加到45.5±6.6毫升/分钟，潜伏期为11.3±1.3秒，导致该动脉直径增加12.6±1.3%。动脉扩张与记录部位的血管内压力是升高、降低还是保持不变无关。动脉平滑肌似乎能够“感知”这种变形，因此它们的动脉能够根据血流速度的变化自动改变管腔。
