気管支の tone と自律神経系セロトニンの気管支収縮および肺動脈圧上昇作用に及ぼす自律神経系の役割について

抄録

The effects of vagotomy or sympathectomy on bronchoconstriction and pulmonary arterial hypertension following an injection of serotonin into the pulmonary artery were studied quantitatively in anesthetized, thoracotomized dogs.
The degree of bronchoconstriction following serotonin administration markedly decreased after bilateral vagotomy, while no changes were found in the rises of pulmonary arterial pressure either by vagotomy or sympathectomy.
These results might suggest the presence of bronchomotor tone in anesthetized dogs, and indicate that it is mediated by the autonomic nervous system.
