[Enzyme systems of intraluminal and membrane hydrolysis of food substances in growing, adult and old rats].
Simultaneous determination of pancreatic proteases, alpha-amylase, lactase and alkaline phosphatase in 2-, 6- and 28-month rats showed deep alterations on the level of cavitary and membrane digestion. Total hydrolytic potential for proteins and carbohydrates is rather high in growing rats and gradually reduces in old animals. These alterations in growing animals are mainly actualized through the small intestine enzymes while in adolescent and old rats - through the pancreatic enzyme systems.
