Membrane hydrolysis and carbohydrate transport were determined 2 hours after bread or meat feeding of rats on the 4th, 7th, and 14th day after the ligation of the bile-pancreatic duct in various segments of the small intestine. Even with a sharp reduction of the amylolytic activity of the mucosa surface, the transport of glucose released during the membrane hydrolysis of starch was retarded much less. During observation for two weeks the intensity of starch glucose transport increased sharply in preparations of the intestine in bread-fed rats, but fell in meat-fed rats. The differences between the sucrose hydrolysis level and the free-glucose transport were insignificant in both groups of rats. The data obtained are discussed in the light of A. M. Ugolev's hypothesis on plastic organization of the digestive-transport conveyer.
在大鼠胰胆管结扎后的第4、7和14天,于小肠各段分别给大鼠喂食面包或肉类2小时后,测定其膜水解和碳水化合物转运情况。即使黏膜表面的淀粉酶活性急剧降低,淀粉膜水解过程中释放的葡萄糖转运受抑制程度也要小得多。在为期两周的观察中,喂食面包的大鼠小肠制剂中淀粉葡萄糖转运强度急剧增加,而喂食肉类的大鼠则下降。两组大鼠的蔗糖水解水平和游离葡萄糖转运之间的差异不显著。根据A.M.乌戈列夫关于消化 - 运输传送带可塑性组织的假说对所得数据进行了讨论。
