Abstract
Electrical stimulation in lateral sites of the upper cervical spinal cord evoked vasodilatation after adrenergic blockade. Sympathetic fibres mediating sustained vasodilatation were shown to be separate from adrenergic sympathetic fibres since the adrenergic vasoconstrictor response in the paw evoked by vasomotor stimulation in the medulla was not reversed to vasodilatation after bretylium.
摘要
对上颈段脊髓外侧部位进行电刺激，在肾上腺素能阻断后可诱发血管舒张。介导持续性血管舒张的交感神经纤维被证明与肾上腺素能交感神经纤维是分开的，因为在给予溴苄铵后，延髓血管运动刺激诱发的爪部肾上腺素能血管收缩反应并未逆转为血管舒张。
