title: [Hydrolases of the digestive organs during ontogenesis].
abstract: A wide variety of enzymes actualizing membrane hydrolysis of nutrients and their distribution in the gastro-intestinal tract were characterized in one-day old and adult rats and rabbits. The comparison of enzymatic activities of various animal species suggests that some enzymes are responsible for the adaptation to milk diet (lactase), others--to definitive nutrition (invertase, maltase). A number of enzymes (peptidase, alkaline phosphatase) do not depend on the type of nutrition. High activity of some hydrolases in the colon has been demonstrated confirming the A. M. Ugolev hypothesis of its digestive functions in the early ontogenesis.
