[The action of timoptin peptides on the hemostatic system].

Repeated introduction of thymus polypeptide drug thymoptine (8 times every 24 hours, 1 microgram/kg) led to the increase in total and non-enzymatic fibrinolytic activity of blood plasma and the decrease in fibrinogen concentration. Thymoptine could lyse non-stabilized fibrin and cause depolymerization of aggregates of fibrin monomer in virto. Highest depolymerization activity was observed at thymoptine concentration of 10 micrograms/ml.
