The role of the autonomic nervous system in the pressor response to the electrical stimulation of different gastric zones has been studied in rats. The stimulus was applied before and after the following interventions: bilateral vagotomy, ganglionic blockade, alpha-adrenergic receptor blockade and beta-adrenergic receptor blockade. After the ganglionic blockade no pressor responses to the electrical stimulus were observed. After the alpha-adrenergic blockade a lower pressor response was observed. A hypertensive response can be induced by mechanical, chemical or electrical stimulation of gastric receptors. It is concluded that the pressor reflex following the application of an electrical stimulus on different zones of the digestive tract is mediated by the sympathetic nervous system and that the efferent pathways are mainly alpha-adrenergic ones.
在大鼠中研究了自主神经系统在对不同胃区进行电刺激时升压反应中的作用。在以下干预前后施加刺激：双侧迷走神经切断术、神经节阻断、α-肾上腺素能受体阻断和β-肾上腺素能受体阻断。神经节阻断后，未观察到对电刺激的升压反应。α-肾上腺素能阻断后，观察到较低的升压反应。机械、化学或电刺激胃感受器可诱发高血压反应。得出的结论是，对消化道不同区域施加电刺激后的升压反射由交感神经系统介导，传出途径主要是α-肾上腺素能途径。
