In anesthetized curarized cats effects of high frequency stimulation of anterior, ventromedial, and posterior hypothalamus on arterial blood pressure (ABP) and on perfusion pressure of the coronary and brachial arteries were studied. The stimulation induced vasoconstriction of coronary vessels and increased the ABP. In most experiments, especially in case of stimulation of anterior hypothalamus, simultaneously with increase of perfusion pressure of the coronary artery, a decrease of the brachial artery perfusion pressure was revealed. The mechanism of vasodilatation of the brachial artery seems to be related to a direct inhibition of the tonic activity of the vertebral branch of the ganglion stellatum. The descending influence of the hypothalamus in respect to the activity of the inferior cardiac nerve is mainly facilitatory. Mechanisms of neural control of the regional blood flow in coronary and brachial arteries are discussed.
在麻醉并使用箭毒的猫身上，研究了高频刺激下丘脑前部、腹内侧部和后部对动脉血压（ABP）以及冠状动脉和肱动脉灌注压的影响。刺激引起冠状动脉血管收缩并使动脉血压升高。在大多数实验中，特别是刺激下丘脑前部时，在冠状动脉灌注压升高的同时，发现肱动脉灌注压下降。肱动脉血管舒张的机制似乎与直接抑制星状神经节椎动脉分支的紧张性活动有关。下丘脑对心下神经活动的下行影响主要是易化性的。讨论了冠状动脉和肱动脉局部血流的神经控制机制。
