Abstract
Experiments were performed on 8 rabbits under urethane-chloralose anesthesia. Histamine aerosol (5%) administered into the trachea by a cannula produced tonic activity of the phrenic nerve, with discharges also being evident during the expiratory phase. Airway vibration (100 Hz) inhibited this tonic activity and caused silence during the expiratory phase.
摘要
在氨基甲酸乙酯-氯醛糖麻醉下对8只兔子进行了实验。通过插管将组胺气雾剂（5%）注入气管，可产生膈神经的紧张性活动，呼气期也有明显放电。气道振动（100赫兹）抑制了这种紧张性活动，并导致呼气期沉默。
