[Fibrinogen fragment D - inhibitor of fibrinolytic processes].
The effect of fragment D, the end product of fibrinogen degradation, on the course of fibrinolytic reactions and fibrinogenolysis induced by plasmin was studied. It was shown that fragment D beside a high antipolymerizing activity also exerts antifibrinolytic and antifibrinogenolytic action. It was demonstrated electrophoretically that exogenous fragment D can inhibit plasmin degradation of fibrin and fibrinogen at all stages of proteolysis without having direct influence on plasmin. It is assumed that the nature of the antipolymerizing and antifibrinolytic activities of fragment D is determined by dissociating fibrin monomer-fragment D complexes.
