本文对嗜烟者与不吸烟者作比较观察吸烟对固体和液体食物胃内分布和排空的即时作用,并应用氢呼吸试验测定液体的口-盲肠通过时间(MCTT),以对胃排空的变化作进一步评估。材料与方法:15位嗜烟者随机在禁食一夜和停止吸烟12小时后进行两项研究。每一研究时,受试者在5分钟内进食含有20 mBq~(99m)锝标记硫化胶质的固体标准餐,然后即摄胃前后位片,并将此时间定为零时,随
In this paper, the immediate effect of smoking on the intragastric distribution and emptying of solid and liquid foods was observed by comparing smokers and non-smokers and the hydrogen breath test was used to determine the mouth-to-cecum transit time (MCTT) of the liquid in order to empty the stomach For further assessment of the changes. MATERIALS AND METHODS: Fifteen smokers randomized two studies 12 hours after fasting overnight and stopping smoking. At each study, the subjects ate the solid standard meal containing 20 mBq 99mTc-labeled vulcanizate within 5 minutes and then immediately before and after gastric ingestion. When this time was set at zero,
