title: [Plasminogen activation by tissue plasminogen activator on fibrin clots with different surface structures].
abstract: Transformation of fibrinogen into fibrin with consequent formation of the fibrin clot trimeric structure is one of the final steps in the blood coagulation system. The plasminogen activation by the tissue plasminogen activator (t-PA) is one of the fibrinolysis system key reactions. The effect of different factors on transformation of plasminogen into plasmin is capable to change essentially the equilibrium between coagulation and fibrinolytic sections of haemostasis system. We have studied the plasminogen activation by tissue plasminogen activator on fibrin clots surface formed on the interface between two phases and in presence of one phase. The t-PA plasminogen activation rate on fibrin clots both with film and without it the latter has been analyzed. These data allow to assume that the changes of fibrin clot structure depend on its formations, as well as are capable to influence essentially on plasminogen activation process by means of its tissue activating agent.
