【摘要】 1.用皮肤表面电极法记录了100名健康人的胃电图,胃电的基本节律是有规律的慢波,频率为3次/分(平均3.06±0.23次/分),波幅为150微伏(平均153±47微伏)。2.进食后胃电图的波幅增高显著,持续5—20分钟,又出现比进食前波幅降低,约1小时才恢复到进食前的水平。3.在45名受试者中,进行了针刺(或指压)一侧足三里穴,观察对胃电图的影响,38名,占84.4%,表现波幅降低;3名,占6.7%,增强,4名,占8.9%,变化不明显。4.当皮下注射新斯的明或阿托品后,胃电图表现波幅增加或降低的变化。更多还原

【Abstract】 1.Electrogastrograms(EGG)of 100 Chinese normal adults were recordedwith monopolar cutaneous surface(extracellular)electrodes.Gastric basic elec-trical rhythm or spontaneous electric activity has been observed.The mainelectric activity is regular at about 3 cycles/minute(average 3.05±0.23 cycles/minute),and amplitude at approximately 150 μv(average 153±47μv).2.After a meal,the basic electrical rhythm showed an increase in the ampli-tude,then showed a short decrease phase and finally returned to the normal levelafter about an hour.3.The effects of acupuncture of Zu-San-Li on the EGG were eitherinhibitory or excitatory,depending upon the preacupunctural states.4.Following the injection of Neostigmini methylsulfurici 0.25 mg or Atropinisulfatis 0.5 mg,obvious increase or decrease in the amplitude and frequency of theEGG waves was observed.5.The possibility of clinical application of EGG was discussed.更多还原
