[Comparative studies of anticoagulant and fibrinolytic effects of glyprolines Gly-Pro and Gly-Pro-Arg in conditions of immobilization stress].

It has been shown that proline-containing peptides Gly-Pro and Gly-Pro-Arg in vitro had anticoagulant and nonenzymatic fibrinolytic activity. It was established that after intranasal introduction of these peptides to a rat, anticoagulant and fibrinolytic activity of enzymatic and nonenzymatic nature increased in the rat blood. The peptide protective effect against hypercoagulation induced by immobilization stress was found after repeated intranasal introduction of each peptide into the animal.
