Abstract

In anesthetized cats, the enhancement of sympathetic activity and increase of the blood pressure in exclusion of afferents (section of vagosympathetic trunks and clamping of common carotid arteries) as well as the disappearance of the activity in enhanced afferentation, were shown to be transient and to disappear within a few minutes-scores of minutes in spite of the going on deafferentation or enhancement of afferentation. The afferent influences from the arterial baroreceptors seem to have no major significance for the long-term control of sympathetic tone.

摘要

在麻醉猫身上，排除传入神经（切断迷走交感干和钳夹颈总动脉）时交感神经活动增强和血压升高，以及传入增强时活动消失，结果显示这些现象是短暂的，尽管持续进行去传入神经或增强传入神经操作，仍会在几分钟到几十分钟内消失。来自动脉压力感受器的传入影响似乎对交感神经张力的长期控制没有重大意义。
