Abstrakt: We discovered that simple proline-containing peptides Gly-Pro, Pro-Gly, Pro-Gly-Pro, and semax had an antistress protective effect on the organism appearing as anticoagulation system activation. Repeated intranasal injection of each of these peptides to rats prior to acute immobilization stress prevented a hypercoagulation response to prolonged stress lasting 60 min. At the same time there was increase of antithrombotic, anticoagulant, and fibrin depolymerization activity and recovery of enzymatic fibrinolytic activity. Dipeptides were found to have the greatest antistress effect. Our results showed that semax had a protective effect against enhanced blood coagulability resulting from repeated immobilization stress.
