title: [The effect of cow's milk and its hydrolysates on the metabolism of 17-hydroxycorticosteroids and the functional state of the gastrointestinal tract in guinea pigs].
abstract: Two groups of noninbred male guinea pigs (initial bw 250-300 g) received test rations in which 50% of standard ration protein were substituted for milk protein (P 20/80) and its enzymatic hydrolysate (H 20/80). The influence of P 20/80 and H 20/80 on some parameters of the gastro-intestinal tract (GIT) barrier function and 17-OCS metabolism was studied. The action of H 20/80 as compared to P 20/80 was expressed in the intensified excretion of free fraction of 17-OCS and glucuronides. The content of hydroxylated glucocorticoids increased in both fractions. At the same time elevated total proteolytic activity in the gastric mucosa and a tendency to decreased GIT permeability for chicken ovalbumin macromolecules were observed in animals that received H 20/80. It has been suggested that enzymatic hydrolysates of food proteins influence endocrine regulation of metabolic processes.
