[The adaptive characteristics of the small intestine under chronic experimental conditions]

The influence of local substrate loads, both monomeric (glucose) and dimeric (saccharose) ones, on the interrelations between the hydrolysis and transport processes was studied under conditions of a chronic experiment on rats with isolated portions of the small intestine. The use of different substrate loads (glucose, saccharose) made it possible to reveal a difference in the response of various portions of the small intestine. The distal portions are more sensitive to loading than the proximal ones.
