The Status of the Hemostasis System under the Influence of Proline Peptides during the Development of Experimental Metabolic Syndrome.

A comparative study of the influence of regulatory proline peptides Pro-Gly-Pro, Pro-Arg-Pro, Pro-Gly-Pro-Leu, and Arg-Pro-Gly-Pro on the state of the hemostasis system was carried out in an experiment on male rats with metabolic syndrome. Under these conditions, repeated (7-fold) intranasal administration of the peptides in a daily dose of 50 μg/kg resulted in an increase in the anticoagulant potential of the blood, namely, in an increase in the anticoagulant, fibrinolytic, and antiplatelet activity 20 h and 7 days after the last peptide injection. The arginine-containing peptide Arg-Pro-Gly-Pro had the most pronounced and stable effect on haemostasis under these experimental conditions.
