Abstract
In a series of 7 dogs, selective stimulation of the carotid body receptors by hypoxic blood produces an increase of coronary flow and greater release of norepinephrine from the heart; the increase of coronary flow is less marked and the release of norepinephrine is increased after vagotomy. Myocardial norepinephrine content is decreased by carotid body stimulation.
摘要
在一组7只犬中，缺氧血液选择性刺激颈动脉体感受器可使冠状动脉血流量增加，心脏去甲肾上腺素释放增多；迷走神经切断后，冠状动脉血流量增加不太明显，而去甲肾上腺素释放增加。刺激颈动脉体可使心肌去甲肾上腺素含量降低。
