针刺治疗胃肠道运动功能失调有明显的临床疗效,但用现代科学方法探讨其机理的研究仍很少。我们应用高灵敏度的应变传感器(STRAIN GAUGE)直接记录胃运动的变化,为本研究提供了可靠的方法学基础。用10只家兔和13只狗进行实验,在α-氯醛醣麻醉下,打开腹腔,把应变传感器固定在距幽门十二指肠连接处1厘米的胃窦部浆膜壁上。应变传感器连接在电桥上并通过高增益直流放大器在RM-6000型多导生理仪上记录。胃运动以收缩频率(次/分)和振 Acupuncture treatment of gastrointestinal motility disorders have obvious clinical efficacy, but the use of modern scientific methods to study the mechanism of research is still very small. We recorded the change of gastric motility directly with STRAIN GAUGE, which provided a reliable methodological basis for this study. Experiments were performed with 10 rabbits and 13 dogs. The abdominal cavity was opened under a-chloralose anesthesia and the strain sensor was mounted on the serosal wall of the antrum of the antrum 1 cm from the junction of the pylorus and duodenum. Strain sensors are connected to the bridge and recorded on the RM-6000 Multi-Conductivity through a high-gain DC amplifier. Stomach movement to contraction frequency (times / min) and vibration
