[The effect of the peptide constituents of casein hydrolysates on glucose and water absorption in the rat small intestine].
The effects of the peptide constituents of two casein hydrolysates applied to the serosal surface, involved the activation of the water absorption alone. Application of these peptides to the mucosal surface slightly inhibited both the glucose and water absorption. The data obtained suggests the mechanism of the peptides action on the glucose and water absorption in the small intestine.

[The characteristics of the absorption in the small intestine of 2 casein hydrolysates and of an equivalent amino acid mixture].
Using casein hydrolysates and the amino-acid mixture applied to mucosal or serosal surfaces, their effect on the transport of free glycine, glycine formed during glycyl glycine hydrolysis, and galactose, was studied in the small intestine. The data obtained suggest a mechanism of peptide transport in the enterocytes as well as a possibility of a regulatory effect of the peptides contained in casein hydrolysates on the transport of some basic nutrients.

[A urethral tip].
The suggested urethral tip is superior to the known tips and attachments. Its design permits enlarging the range of its application, reducing pain sensations, and improving the asepsis; the tip work may be matched with the work of other urologic instruments according to Charrière's scale; it can be used in both children and adults.

[Low-molecular peptides in food as factors altering the resistance of rats to emotional stress].
The authors studied the resistance of animals to emotional stress when they were given in the diet, as a source of protein, casein and a protein fraction composed of a mixture of amino acids and low-molecular peptides (18 and 2.7%) obtained by reprocessing Saccharomyces cerevisiae yeasts, biomass. The ECG, rheovasogram, systolic arterial pressure, and respiratory rate were studied in rats given a diet containing 18 and 2.7% low-molecular peptides (controls) and in the same animals after 24-hour immobilization. Addition of low-molecular peptides in the indicated concentration to the diet reduced the resistance of animals to emotional stress.
