[Enzyme activity of the rat small intestine mucosa in conditions of repeated exposure to high ambient temperatures].

Acute experiments showed that daily 12-hr heating leads to different changes in fermentative activity (amylase, invertase, glycin-1-leycin-dipeptidase, monoglyceridiypase) in mucous membrane of the small intestine in white rats. These changes are due to not only the decrease of food consumption, but evidently are the result of functional changes in different organs and systems.
