[The effect of high temperature and hydrocortisone on amylolytic and invertase activities of the mucous membrane of the small intestine in early ontogenesis of rats].

Abstract

In experiments on 16-19 day rats, studies have been made of the effect of 2-hour heat exposure (40-41 degrees ) and hydrocortizone injection (4 mg per 100 g of body weight) on gamma-amylolytic and invertase activities of homogenized ad inside-turned pieces of proximal, middle and distal parts of the small intestine. It was shown that thermal stress results in a sharp increase of the enzymic activities of homogenates and total pieces of proximal and middle parts of the intestine. In distal parts, the enzymic induction is less significant or even completely absent. Hydrocortizone injections evoke similar changes, although the latter are more evident. On the basis of the data obtained, it is suggested that the effect of thermal factor on the synthesis of intestinal enzymes is realized via the hormones of suprarenal cortex.
