[Relation between quality of dietary protein, plasma corticosteroid concentration and various enzyme activities in liver and mucosa of small intestine].

Comprehensive studies were performed in Wistar rats on the relations between the dietary protein quality and the function of the adrenocortical system. The authors determined: the increase in body mass, the urea and corticosteroid concentrations in the blood plasma, the GOT (EC 2.6.I.I.) and GPT (EC 2.6.I.2.) activities in the liver, the reactivity of the adrenocortical system in vitro, the ACTH content in the hypophyses and the content of corticosteroid-binding globulin in the blood plasma. In adrenalectomized and normal rats as well as in rats treated with corticosterone or cortisol, the authors determined the GPT, GOT, amino-acid aryl amidase (EC 3.4.I.2.) and tripeptidase (EC 3.4.I.3.) activities in the liver and the mucosa of the small intestine, and the total, alpha and beta-amylase activities in the small intestine.
