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.
