Sustained thrombolysis with DNA-recombinant tissue type plasminogen activator in rabbits.
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. ...
متن کاملCoronary thrombolysis with recombinant human tissue-type plasminogen activator.
The thrombolytic potency and myocardial infarct--sparing potential of recombinant tissue-type plasminogen activator (rt-PA) were studied in electrocardiographically monitored, open-chest, anesthetized dogs. Localized coronary thrombosis was produced in the left anterior descending artery by endothelial injury and instillation of thrombin and fresh blood. After 2 hr of stable thrombotic occlusio...
متن کاملCoronary thrombolysis with intravenously administered human tissue-type plasminogen activator produced by recombinant DNA technology.
Coronary thrombolysis was induced by intravenous infusion of human tissue-type plasminogen activator (recombinant human t-PA or rt-PA) obtained by expression of the cloned gene in a mammalian cell system. Thrombolysis was detected by the appearance of reperfusion arrhythmia and confirmed by repeat angiography in anesthetized dogs with 1-hr-old thrombi of the left anterior descending coronary ar...
متن کاملEffects of therapeutic doses of heparin on thrombolysis with tissue-type plasminogen activator in rabbits.
The objective of the study was to evaluate the ability of heparin to enhance the thrombolytic effect of recombinant tissue type plasminogen activator (rt-PA) and to prevent thrombus growth during and after thrombolysis with rt-PA. In the thrombolysis studies, three groups of rabbits were infused with rt-PA at a dose of 0.5 mg, 1 mg, or 2.5 mg over 3 hours, respectively. Rabbits in each group we...
متن کاملEarly intravenous thrombolysis with recombinant tissue-type plasminogen activator in vertebrobasilar ischemic stroke.
BACKGROUND The optimal therapy of vertebrobasilar ischemic stroke is under debate. In the case of underlying basilar artery occlusion, intra-arterial thrombolysis is recommended. Because this pathologic condition is rarely found and the procedure is time consuming and restricted to specialized centers, the question arises whether early intravenous thrombolysis could also effectively be applied ...
