家兔右侧主动脉弓减压神经压力感受器的部位,形态学观察已证明其存在(Nonidez,J.F.1935)。本文报告用生理实验方法加以证明的结果:用盲端加压法使麻醉情况下的23只兔右侧锁骨下——颈总动脉隔离段内压力升高时,引起19只兔体循环动脉血压的反射性下降。对呼吸无影响。该反射的阈值为60—80毫米汞柱,平均血压下降达25毫米汞柱。在一定范围内刺激愈强则反射性降压亦愈明显,引起最
The site of decompression of the right aortic arch in the rabbit aortic arch has been shown by morphological observations (Nonidez, J. F. 1935). This article reports the results of physiological experiments to prove the results: the blind end of the pressure of anesthetized 23 cases of right subclavian - common carotid artery in the isolation segment increased pressure, causing 19 rabbits systemic arterial pressure Reflectivity decreased. No effect on breathing. The threshold for this reflex is 60-80 mmHg, with an average blood pressure drop of 25 mmHg. Within a certain range, the stronger the reflex is the more obvious antihypertensive, causing the most
