用吸附电极引导大鼠胃体部的电活动。慢波可分为双相波和间期。双相波的持续时间为6.26±1。36S,间期为6.54±1.94S,慢波周期为12.74±2.00S,幅度为0.96±0.04mV,频率为5.03±0.11C/min。快波负载于双相波之上,其幅度可达3my。带快波的慢波占整个慢波的68.4％。用张力换能器记录的胃运动与胃电密切相关。胃电先于胃运动2.68±0.01S.当快波频率增加时,胃运动就增强,反之则减弱。但是,只有慢波而无快波也有胃的收缩运动。乙酰胆硷明显增强胃电和胃运动。阿托品对胃电的影响不恒定,有时可抑制快波而有时则不抑制。肾上腺素对胃电和胃运动有抑制作用。
Adsorption electrodes lead to electrical activity in rat gastric body. Slow wave can be divided into biphasic wave and interval. The duration of biphasic wave was 6.26 ± 1.36S, with an interval of 6.54 ± 1.94S, a slow wave period of 12.74 ± 2.00S, an amplitude of 0.96 ± 0.04mV and a frequency of 5.03 ± 0.11C / min. Fast wave load on the biphasic wave, the magnitude of up to 3my. Slow waves with fast waves account for 68.4% of the total slow waves. Tension transducer recorded gastric motility and gastric closely related. Gastric stomach movement before the 2.68 ± 0.01S. When the fast wave frequency increases, the gastric motility will increase, otherwise weakened. However, only slow waves without fast waves have gastric contractility. Acetylcholine significantly enhances gastric and gastric motility. Atropine on the gastric electrical effects are not constant, and sometimes can inhibit the fast wave and sometimes do not inhibit. Epinephrine gastric and gastric motility inhibition.
