Influence of high temperature on the enzyme activity of the small intestine in thyroidectomized rats]

It was revealed in acute experiments that exposure to high temperature changed the invertase, dipeptidase, lipolytic and alkaline phosphatase activity of the small intestinal mucosa in rats. The direction of these changes and their degree differed in the thyroidectomized and sham-operated animals. It is suggested that the thyroid hormones took part in the reaction of the fermentative systems of the small intestine to the action of the thermal factor.
