Thrombolytic Therapy and Proteolysis of Factor V

Proteolysis, fibrinolysis, and coagulation. Significance in thrombolytic therapy.

Proteolysis of von Willebrand factor after thrombolytic therapy in patients with acute myocardial infarction.

In 20 patients with acute myocardial infarction (AMI) treated with streptokinase (SK, n = 7), recombinant single-chain tissue plasminogen activator (rt-PA, n = 7) or urokinase (UK, n = 6), the behavior of plasma von Willebrand factor (vWF) was studied before and 1.5, 3, 24, 48, and 72 hours after beginning thrombolytic therapy. vWF antigen (vWF:Ag) was high in plasma, especially after SK. The r...

FACTOR V AND VIII INHIBITOR IN PATIENTS WITH COMBINED FACTOR V AND VIII DEFICIENCY

Patients with coagulation factor(s) deficiency who use coagulation therapy are susceptible to forming inhibitors against coagulation factor(s). In this survey we detected factor V and VIII inhibitor in ten patients with combined deficiency of factors V and VIII from north east of Iran (Khorassan province). It was revealed in our survey that eight patients had both factor V and factor VIII i...

Thrombolytic therapy.

Thrombolytic therapy, which involves the administration of agents designed to increase fibrinolytic capacity, has been utilized in respiratory medicine for more than 50 years. A variety of agents have been used to effect thrombolysis, including urokinase plasminogen activator (uPA) and streptokinase. Tissue plasminogen activator (tPA) has also been used to effect thrombolysis. Both uPA and tPA ...

Thrombolytic Therapy.

The purpose of this communication is to review briefly the agents available at the present time for use in thrombolytic therapy and to indicate why we believe that at the present time streptokinase is the only suitable agent for extended clinical trial. An account will then be given of the use of streptokinase administered by local perfusion in the treatment of peripheral arterial occlusion and...
