为了探讨除由于胃底强制性收缩引起的胃内压力以外,其他因素是否能调节胃液排空,作者对健康受试者进行了实验观察.当用体外压力系统保持胃内压恒定时,作者测定了不同渗透压与成份的胃液的排空.初步实验显示胃内压与排空率呈直线关系.但指出正常胃内压(7cmH_2O)不足以保持正常排空,当胃内压为20CmH_2O时,含盐278mo/kg的30M葡萄糖等渗液以49.9±0.5ml/min
In order to investigate whether other factors, in addition to intragastric pressure due to obligatory contraction of the gastric fundus, regulate gastric emptying, the authors conducted an experimental observation of healthy subjects.When using an in vitro pressure system to keep the intragastric pressure constant, the authors determined The gastric emptying with different osmotic pressure and ingredient was emptied.A preliminary experiment showed that there was a linear relationship between gastric pressure and emptying rate.However, normal gastric pressure (7cmH_2O) was not enough to maintain normal emptying.When the intragastric pressure was 20cmH_2O, Salt 278mo / kg of 30M glucose isotonic solution to 49.9 ± 0.5ml / min
