Using accumulating preparations of the mucose, studies have been made on the rate of accumulation of the glucose from 11 mM solutions of glucose, maltose and starch in proximal, intermediate and distal parts of the small intestine of 2--13-week rats. It was demonstrated that in 2-week animals, rather intensive transmembrane transport of "free" glucose takes place in the proximal and medial parts of the small intestine, the transport of glucose in the form of maltose or starch being absent. At later stages of postnatal life, especially to the onset of definitive nutrition, together with the induction of alpha-glucosidase systems, gamma-amylase and maltase transporting mechanisms are formed which provide for the adaptation of the organism to qualitatively new feeding conditions.
利用黏液积累制剂，对2至13周龄大鼠小肠近端、中间和远端部分从11 mM葡萄糖、麦芽糖和淀粉溶液中积累葡萄糖的速率进行了研究。结果表明，在2周龄的动物中，小肠近端和中部发生了相当强烈的“游离”葡萄糖跨膜转运，不存在麦芽糖或淀粉形式的葡萄糖转运。在出生后后期，尤其是到确定营养开始时，随着α-葡萄糖苷酶系统的诱导，形成了γ-淀粉酶和麦芽糖酶转运机制，使机体适应性质全新的喂养条件。
