[ACTIVATION OF PROTEIN C IN THE IN VITRO THROMBOLYSIS].

Physiological conditions of formation and subsequent lysis of thrombus were reconstituted in vitro in our research. Thrombus formation was initiated either by addition of exogenous thrombin or by contact of blood with anionic surface, which stimulates spontaneous coagulation of blood. Tissue plasminogen activator and/or protein C were previously added in the blood sample.
