[The action of regulator peptides with different biological activities on the process of fibrin-monomer polymerization and on nonenzymatic fibrinolysis].
It is shown that preparations of regulatory peptides (RP): interleukin-1, thymoptin, and the endogenous nonpeptide opioid salsalinol produce a marked depolymerization effect on the fibrin-monomer and display nonenzymatic fibrinolytic activity in relation to unstabilized fibrin. Preparations of regulatory peptides thymalin and diphensin of rabbits intensify fibrin polymerization. A single intravenous infusion of diphensin preparation inhibits nonenzymatic fibrinolysis of blood plasma in vivo and in vitro. Repeated intramuscular injections of the immunoactive preparation thymoptin intensify the fibrinolytic properties of blood plasma in rats.
