现已证明餐后空肠吸收水和电解质的增加与消化的中枢相和胃相无关,但其神经、体液信号的源点尚不清楚。本文旨在验证食物引起空肠吸收反应信号源于小肠这一设想,并试图确定营养成分及渗透压在此反应中的作用。作者用犬的近端游离空肠25cm作Thiry-Vella瘘,另向幽门远端5cm十二指肠插入8cm聚硅酮胶管。2周后作空肠吸收试验,每次试验包括1小时基础期和3小时实验期。试验分10组:组一(对照组)不喂养;组二喂标准混合餐(含52％蛋白质,36％脂肪,12％碳水化合
It has been shown that the increase of postprandial jejunal absorption of water and electrolytes has nothing to do with the digestive central phase and gastric phase, but the source of neural and humoral signals is unclear. This article aims to validate the idea that food causes the jejunal response to enter the small intestine and to try to determine the role of nutrients and osmotic pressure in this reaction. The author used dog proximal free jejunum 25cm Thiry-Vella fistula, the other to the distal pylorus 5cm duodenum inserted 8cm silicone hose. Two weeks later for the jejunal absorption test, each test includes 1 hour basic period and 3 hours experimental period. Test group 10: group one (control group) did not feed; group two fed standard mixed meal (containing 52% protein, 36% fat, 12% carbohydrate
