[Effect of cold stress on the postnatal formation of the carbohydrate hydrolysis and transport mechanisms in the rat small intestine].

In acute experiments on rats using accumulating mucosa preparation (AMP) method it was shown that cold training (daily 2-hour exposure to 6-7 degress C) exerts stable inhibitng effect to postnatal formation of maltase- and gamma-amilase transport digestive-absorbtive system and does not change the dynamics of its own transport. The same training program significantly accelerates the rate of hydrolytic-transport conveyor on the cell membrane external surface in rats aged from 10 to 17 days.
