Abstract

The experiments carried out showed the presence- in sympathetic nerve endings ot the carotid sinus- of alpha and beta adrenoceptors which by means of respective negative and positive feedback processes, modulated NA release induced by a sympathetic nerve stimulation. Similarly, Pgs acted by means of a negative feedback mechanism to regulated adrenergic neuro-transmission in carotid sinus but they could not be considered as the chemical mediators of either alpha or beta adrenoceptors.

摘要

所进行的实验表明，在颈动脉窦的交感神经末梢中存在α和β肾上腺素能受体，它们通过各自的负反馈和正反馈过程，调节交感神经刺激诱导的去甲肾上腺素释放。同样，前列腺素通过负反馈机制作用于调节颈动脉窦中的肾上腺素能神经传递，但它们不能被视为α或β肾上腺素能受体的化学介质。
