[Relationship between the quality of dietary proteins and the functional status of the adrenal cortex. 5. Content of corticosterone and cortisol in the liver and in the mucosa of the small intestine of rats fed with proteins of various quality (estimation of binding capacity for corticosteroids)].

Relationships between the Quality of Dietary Proteins and the Functional State of the Adrenal Cortex. (5) Content of Corticosterone and Cortisol in the Liver and in the Mucosa of the Small Intestine of Rats Fed Proteins of Varying Quality (Estimation of the Binding Capacity for Corticosteroids). Growing male Wistar rats were used to investigate in which way the quality of dietary proteins (maize gluten and maize gluten supplemented with amino acids) influenced the content of corticosteroids in the liver and in the mucosa of the small intestine of untreated rats (N), adrenalectomized animals (AE) and animals treated with corticosteroids (N + S). In AE animals the content of corticosteroids in the tissues was very low. In N + S animals of both dietary groups the mucosa of the small intestine contained more corticosteroids than the liver; the content of corticosteroids in the mucosa, however, was also found to vary in dependence upon the diet fed. The mucosa of N + S animals receiving dietary proteins of high quality contained more corticosteroids; this indicates a higher binding capacity of the mucosa for corticosteroids.
