[Enzymatic adaptation of the pancreas and small intestine to food composition (the example of carbohydrases)].

In two series of experiments on rats, the effect of high protein as well as fat and carbohydrate diets of carbohydrases activity of the pancreas and the small intestine was studied; in the first series, the animals had the specialized diets for 4, 15 and 30 days, while in the second series--for 7 days. In the 1st series food composition produced an obvious effect on gamma--amylase, maltase and sacrase activities of the intestinal mucosa, whereas in the 2nd series the effect was insignificant which can be accounted for by somewhat different conditions of the experiments. The data suggest that adaptation of pancreatic and small intestine's enzyme systems to food composition should be considered an integrated reaction.
