Reactive hyperemia was diminished when blood of varying oxygen content was infused into the vascular bed distal to an occluded coronary artery. The degree of response appeared to be related to the oxygen content of the infused sample. However, plasma and saline infusions also caused a reduction in reactive hypermia. It is therefore possible to conclude that the prevention of the fall in intravascular pressure plays an important role in the regulation of vascular smooth muscle tone in the dog heart.
当将不同氧含量的血液输注到闭塞冠状动脉远端的血管床时，反应性充血减少。反应程度似乎与输注样本的氧含量有关。然而，输注血浆和生理盐水也会导致反应性充血减少。因此可以得出结论，防止血管内压力下降在犬心脏血管平滑肌张力的调节中起重要作用。
