Abstract
- Fundic secretion of HCl and pepsin was studied in sheep with both fundic and antral pouches. The antral pouches were of the entire pyloric region. Continuity of the alimentary tract was restored by an abomasoduodenal anastomosis. 2. Secretion from fundic pouches was continuous. It was reduced in volume and acidity, was pepsin output, by resection of the antral pouches. 3. Teasing with food, feeding and injection of pentagastrin stimulated fundic acid and pepsin secretion in animals with antral pouches before and after antrectomy. 4. Pouches prepared from the entire pyloric region showed continuous secretion with variations not related to feeding or fasting. Antral secretion was increased after s.c. injections of histamine, carbachol and pentagastrin. 5. It is concluded that although the pyloric antrum contributes to the magnitude of the secretory response of an abomasal fundic pouch, the direction of the secretory response is similar whether or not the pyloric antrum is present as a separated pouch, or is removed.
摘要
- 对具有胃底和胃窦袋的绵羊的胃底盐酸和胃蛋白酶分泌进行了研究。胃窦袋取自整个幽门区域。通过皱胃十二指肠吻合术恢复了消化道的连续性。2. 胃底袋的分泌是持续的。切除胃窦袋后，其分泌量和酸度降低，胃蛋白酶输出量也减少。3. 用食物逗弄、喂食和注射五肽胃泌素可刺激胃窦袋动物在胃窦切除术前和术后的胃底酸和胃蛋白酶分泌。4. 取自整个幽门区域的袋显示出持续分泌，其变化与进食或禁食无关。皮下注射组胺、卡巴胆碱和五肽胃泌素后胃窦分泌增加。5. 得出的结论是，尽管幽门窦对皱胃胃底袋的分泌反应幅度有贡献，但无论幽门窦是以分离的袋形式存在还是被切除，分泌反应的方向都是相似的。
