Effect of a New Synthetic Peptide Preparation AСTH15-18PGP on the Hemostasis System in Rats

Resumo

We studied the effect of chronic intranasal and peroral administration of a new peptide preparation AСTH_15-18PGP in a dose of 100 mg/kg body weight on the state of vascular-platelet and plasma hemostasis in animals. It was found that this synthetic regulatory peptide administered intranasally can produce antiplatelet, anticoagulant, and antifibrin-stabilizing effects on the blood plasma in healthy rats. In both administration routes, the peptide induced activation of the anticoagulation system of the hemostasis by increasing enzymatic and non-enzymatic fibrinolysis; after intranasal administration, the fibrinolytic effects were more pronounced.
