目前认为,非溃疡性消化不良的许多症状与上消化道功能紊乱有关,而PGE_2类似物恩前列素能增加正常人胃排空,并引起腹部不适。本文应用实时超声检测恩前列素对胃窦、幽门及近段十二指肠的作用。材料和方法:10位健康受试者(男6、女4,平均年龄37岁),分两次检查。一次于饮肉汤前1小时先服恩前列素35μg,另一次仅饮肉汤,以便对照。检查前受试者禁食一夜。检查时稍后倾坐于椅上,饮500ml(37℃)肉汤(20kcal)后。立即用5或7.5MHz探头横断扫查幽门,显示胃窦、幽门和近段十二捐肠,以观察胃十二指肠活动的协调(窦球协调)、幽门开放及十
Currently, many of the symptoms of non-ulcer dyspepsia are associated with dysfunctional upper gastrointestinal tract, whereas the prostaglandin analogue PGE 2 increases normal gastric emptying and causes abdominal discomfort. In this paper, real-time ultrasonography was used to detect the effect of enprost on gastric antrum, pylorus and proximal duodenum. MATERIALS AND METHODS: Ten healthy subjects (male 6, female 4, mean age 37 years) were examined in duplicate. One hour before serving broth, erlotrun 35 μg was administered, and the other only broth was administered for control. Subjects were fasted overnight before examinations. Sit later on the chair in the examination, drink 500ml (37 ℃) broth (20kcal) after. The pylorus was transected with a 5 or 7.5 MHz probe immediately to reveal the antrum, pylorus and proximal twelve intestines to observe the coordination of gastroduodenal activity (sinus ball coordination), pyloric opening and ten
