[Effect of stress on parietal hydrolysis of saccharose in rats].

Experiments were conducted in albino rats of both sexes and different age; a study was made of the activity of the intestinal invertase directly after 4-hour immobilization. There was revealed a depressive effect of stress on the activity of membrane digestion and enzyme production in the intestinal epithelal cells, and a definite dependence of the observed effect on the animals' sex age. The latter was expressed in a greater fall of the invertase activity in young females and in its marked variations in old female rats.
