The influence of low- and high-frequency stimulation of anterior, tuberal and posterior hypothalamic areas on the spontaneous rhythmogenesis in the ureter smooth muscles and on arterial blood pressure, was studied in anesthetized cats. High-frequency stimulation of all hypothalamic areas induced pressor responses with activating effects on motor activity of the ureter. The changes in the ureter rhythmic activity were synchronous with those of systemic arterial blood pressure. The low-frequency stimulation induced both pressor and depressor responses in different proportion. The depressor responses were not accompanied by any changes of the ureter rhythmic activity. Possible mechanisms of reversal of vasomotor responses in stimulation of hypothalamus, organization of sympathico-activating and sympathoinhibitory mechanisms and hypothalamic regulation of rhythmogenic function of the ureter, are discussed.
在麻醉猫身上研究了下丘脑前部、结节部和后部的低频和高频刺激对输尿管平滑肌自发节律发生以及动脉血压的影响。对所有下丘脑区域的高频刺激均诱发了升压反应，并对输尿管的运动活动产生激活作用。输尿管节律性活动的变化与全身动脉血压的变化同步。低频刺激以不同比例诱发了升压和降压反应。降压反应未伴有输尿管节律性活动的任何变化。文中讨论了刺激下丘脑时血管运动反应逆转的可能机制、交感激活和交感抑制机制的组织以及下丘脑对输尿管节律生成功能的调节。
