Fifty-six experiments were performed in rabbits anesthetized by urethane or sodium pentobarbital. Baroreceptor (aortic nerve) and post-ganglionic sympathetic (renal nerve) activities were recorded, and peripheral resistances were determined after infusion of beta-adrenoceptor blocking agents (propranolol, pindolol, timolol). A progressive vasodilation was observed after the onset of infusion of the 3 drugs; at the same time arterial pressure decreased, but aortic flow did not vary significantly. Baroreceptor activity was enhanced, whereas efferent renal nerve activity was decreased.
在由氨基甲酸乙酯或戊巴比妥钠麻醉的兔子身上进行了56次实验。记录压力感受器（主动脉神经）和节后交感神经（肾神经）的活动，并在输注β-肾上腺素能受体阻滞剂（普萘洛尔、吲哚洛尔、噻吗洛尔）后测定外周阻力。在输注这3种药物后观察到进行性血管舒张；同时动脉压下降，但主动脉血流量无显著变化。压力感受器活动增强，而肾神经传出活动减少。
