Tissue type plasminogen activator (t-PA) is an effective thrombolytic agent in experimental animals. The duration of the thrombolytic effect of infused t-PA is unknown. We compared the duration of the thrombolytic effect of t-PA with streptokinase by measuring the lysis of 125I-fibrin-labeled thrombi in rabbit jugular veins at different times after a bolus injection of the fibrinolytic agents. ...

BACKGROUND Evidence-based guidelines for the treatment of patients with acute myocardial infarction (AMI) have been published and disseminated by the American College of Cardiology and the American Heart Association. Few studies have examined the rates of adherence to these guidelines in eligible populations and the influence of age and gender on highly effective AMI treatments in community hos...

The major goal of reperfusion strategies in patients with acute myocardial infarction is to achieve patency of the infarct-related artery . Improvement in ventricular function and survival are related to initial and continued potency of this artery . The greater initial patency of the infarct-related artery after intravenous recombinant tissue-type plasminogen activator (r(-PA) compared with th...

Regional thrombolytic therapy for arterial occlusion of the limbs uses several catheter-guided techniques and various infusion methods and therapeutic schemes. There is no definite proof of superiority of any agent in terms of efficacy and safety. A meta-analysis of randomized trials comparing surgery to thrombolysis in leg ischemia shows no significant difference in major amputation and mortal...

Despite major advances made over the last decade, mortality following acute myocardial infarction (MI) is still high even for patients treated with the "front-loaded" recombinant tissue-type plasminogen activator (rt-PA) regimen: 30-day mortality is 6.3%, and it is associated with fatal cerebral hemorrhage in 1.5%. Further improvement of short- and long-term prognosis can be achieved if infusio...

Thirty-one patients with acute cerebral infarction were treated with the thrombolytic agent urokinase for either a single or a double infusion period, each of ten hours. The effects of urokinase therapy administered at dosage rates of 1,200, 1,500 or 1,700 CTA urokinase units per pound of body weight per hour were followed by serial blood coagulation and other biochemical studies. In the dosage...

The developing world carries the highest burden of stroke mortality and stroke-related disability. The number of stroke patients receiving r-tPA in the developing world is extremely low. Prehospital delay, financial constraints, and lack of infrastructure are main barriers of thrombolysis therapy in developing countries. Until a cheaper thrombolytic agent and the proper infrastructure for utili...

OBJECTIVE Ultrasound enhances thrombolysis when combined with a thrombolytic and a contrast agent. This study aimed to evaluate the thrombolytic effect of our tissue plasminogen activator (tPA)-loaded echogenic liposomes (ELIP) in an in vivo clot model, with and without ultrasound treatment. METHODS AND RESULTS The femoral arteries of New Zealand White rabbits (n=4 per group) were cannulated....

BACKGROUND Today, thrombosis is one of the most widely occurring diseases in modern life. Drugs with thrombolytic functions are the most effective methods in the treatment of thrombosis. Among them, Douchi fibrinolytic enzyme (DFE) is a promising agent. DFE was isolated from Douchi, a typical and popular soybean-fermented food in China, and it can dissolve fibrin directly and efficiently. A str...

In this review paper, an emphasis is made to focus on the history, source, structure, mode of action, and application Nattokinase. The reveals that Nattokinase can act as a potent thrombolytic agent compared other agents which are commercially available. Studies NK have also be proved it useful for dissolving blood clots by converting plasminogen plasmin, further fibrin clots. been isolated fro...
