本文观察了中药枳壳、小茴香混合水煎剂(以下简称枳茴汤)对正常大鼠及800 rad γ射线照射大鼠胃肠肌电的影响.正常大鼠灌胃枳茴汤(0.25ml/100g体重,含生药0.25mg)后即刻、30min、1h及6h整个胃肠道的峰波振幅比灌药前均有不同程度的升高,尤其是给药后1、6h胃窦部、幽门括约肌的峰波振幅升高更明显(p<0.05).800radγ射线照射大鼠灌胃枳茴汤后胃窦部的峰波振幅在灌药后6h即恢复至正常水平,在照射后3天升高,4天比照射前升高显著(p<0.05).这表明枳茴汤具有兴奋胃肠道、增强胃肠运动的作用.对800 rad γ线照射大鼠则能增强胃的收缩,这对改善电离辐射引起的胃排空延迟是有益的. In this paper, the effects of Fructus Aurantii and fennel mixed decoction (hereinafter referred to as Fructus Foenici) on gastrointestinal EMG of normal rats and 800 rad γ-ray irradiated rats were observed.The normal rats were infused with Fructus Foenilus (0.25ml / 100g body weight, containing crude drug 0.25mg) immediately after, 30min, 1h and 6h peak amplitude of the entire gastrointestinal tract than before perfusion were increased to varying degrees, especially after administration of 1,6h gastric antrum, pylorus The amplitude of peak wave in the sphincter increased more significantly (p <0.05). The amplitude of peak wave of gastric antrum in 800 radγ-ray irradiated rats was returned to normal level 6 h after irrigation, (P <0.05), indicating that trifoliate orange juice can stimulate the gastrointestinal tract and enhance gastrointestinal motility.At the 800 rad γ-ray irradiation, it can enhance the gastric contraction, which It is beneficial to improve the delay of gastric emptying caused by ionizing radiation.
