title: [Low-molecular peptides in food as factors altering the resistance of rats to emotional stress].
abstract: 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.
