Abstract
Noradrenaline applied to the dorsal surface of spinal cord segments C6-T1 suppressed the pressor components of the blood pressure reflexes evoked by stimulation of radial nerve afferents in anesthetized cats. Noradrenaline applied to spinal cord segments L4-S1 suppressed pressor reflexes elicited by stimulation of tibial nerve afferents. The increase in noradrenaline concentration from 0.05 to 0.2% enhanced the duration and intensity of this effect.
摘要
将去甲肾上腺素应用于脊髓C6 - T1节段的背表面，可抑制麻醉猫中刺激桡神经传入纤维所诱发的血压反射的升压成分。将去甲肾上腺素应用于脊髓L4 - S1节段，可抑制刺激胫神经传入纤维所诱发的升压反射。去甲肾上腺素浓度从0.05%增加到0.2%，可增强这种效应的持续时间和强度。
