The influence of various gums on the intestinal absorption of glucose and maltose was investigated in the experimental animal. The alterations in the concentrations of sodium and potassium were determined additionally. The following gums were used: alginate (sodium, potassium, calcium salts), Carrageenan, guaran, methylcellulose, carboxymethylcellulose. The absorption of glucose (concentration: 5% = 278 mmol/l) and maltose (concentration: 5% = 139 mmol/l) was not influenced by the addition of gums (concentration: 1%-2%). The hydrolysis of maltose was not inhibited also. Sodium was absorbed from the intestinal lumen if the concentration was higher than 120-150 mmol/l, otherwise sodium was excreted into the lumen. Potassium was absorbed if the potassium concentration was raised above 6-10 mmol/l, otherwise potassium was excreted into the lumen. The neutral gums did not influence the alterations in ion concentration. The gums tested do not influence the digestion and absorption of maltose or glucose. The acid gums are present in the small intestine in the form of their sodium salts. In the large intestine, sodium is exchanged for potassium.
在实验动物中研究了各种胶对葡萄糖和麦芽糖肠道吸收的影响。另外还测定了钠和钾浓度的变化。使用了以下几种胶：藻酸盐（钠盐、钾盐、钙盐）、角叉菜胶、瓜尔豆胶、甲基纤维素、羧甲基纤维素。添加胶（浓度为1%-2%）对葡萄糖（浓度：5% = 278 mmol/l）和麦芽糖（浓度：5% = 139 mmol/l）的吸收没有影响。麦芽糖的水解也未受到抑制。如果钠浓度高于120-150 mmol/l，钠会从肠腔被吸收，否则钠会排泄到肠腔中。如果钾浓度升高到6-10 mmol/l以上，钾会被吸收，否则钾会排泄到肠腔中。中性胶不影响离子浓度的变化。所测试的胶不影响麦芽糖或葡萄糖的消化和吸收。酸性胶在小肠中以其钠盐的形式存在。在大肠中，钠会与钾进行交换。
