Abstract

The relation between carotid sinus, aortic and subclavian nervous activities and blood pressure during cardiopulmonary bypass in Rabbits appears to be normal in animals whose maximal arterial pressure is greater than or equal to 90 mmHg. In Rabbits whose maximal arterial pressure is less than 90 mmHg, the activities are generally higher and no positive correlation is found between activities and blood pressure. These high activities are not of chemoceptor or efferent origin. Therefore we assume that these high activities are of baroceptor nature. Their possible origins are discussed.

摘要

在最大动脉压大于或等于90mmHg的家兔体外循环期间,颈动脉窦、主动脉及锁骨下神经活动与血压之间的关系似乎正常。在最大动脉压小于90mmHg的家兔中,这些神经活动通常较高,且未发现神经活动与血压之间存在正相关。这些高神经活动并非源于化学感受器或传出神经。因此,我们认为这些高神经活动具有压力感受器性质。文中还讨论了它们可能的起源。
