目的 :为探索耳廓“胸肺区” (TPA)对延髓压力敏感区 (BBA)的神经元活动有无调整作用 ,以 2 2只家兔为实验动物 ,乌拉坦麻醉 ,用谷氨酸 (Glu)兴奋和γ -氨基丁酸 (GABA)抑制BBA神经元 ,观察其对呼吸、循环功能的影响 ;然后电针刺激TPA ,观察其对用谷氨酸 (Glu)兴奋和γ -氨基丁
Objective: To explore whether the auricle “chest and lung area” (TPA) can modulate the neuronal activity in the medulla oblongata pressure-sensitive zone (BBA). Twenty-two rabbits were used as experimental animals and were anesthetized with urethane Glu) and gamma - aminobutyric acid (GABA) to inhibit the BBA neurons to observe their effects on respiration and circulatory function. Then the electroacupuncture stimulation of TPA was performed to observe the effects of glutamate (Glu)
