The present study compares the efficacy of two formulations of encapsulated streptokinase to streptokinase in a rabbit model of carotid artery thrombosis. Arterial thrombosis followed the injection of thrombin mixed with autologous whole blood into a carotid artery of New Zealand white rabbits. Thirty minutes after the confirmation of an occlusive thrombus, one of four streptokinase formulation...

Inhibitors of fibrinolysis may be divided into naturally circulating inhibitors and antifibrinolytic agents. Natural inhibitors are present in plasma and are components of blood cells, especially platelets. Several types of antifibrinolytic activity can be distinguished: antiplasmin activity, and anti-activator activity against streptokinase, urokinase, and tissue activator induced plasminogen ...

Acute myocardial infarction (AMI) is one of the main leading causes of mortality and morbidity. Despite the progress in the treatment of AMI, streptokinase is still being used in many countries. Because of the critical condition of patients with AMI and complications of streptokinase therapy, this study was performed to evaluate the pattern of adverse drug reaction (ADRs) induced by streptokina...

background: streptokinase is a bacterial protein produced by different beta hemolytic streptococci and widely used in thrombolytic treatment. the main disadvantage of using streptokinase is antibody formation which causes allergic reaction to neutralize effects of streptokinase therapy. aim of this study was investigate of recombinant mutant streptokinase fibrinolytic activity. m aterials and m...

To investigate the role of allelic variants of streptokinase in the pathogenesis of acute poststreptococcal glomerulonephritis (APSGN), site-specific integration plasmids were constructed, which contained either the non-nephritis-associated streptokinase gene (skc5) from the group C streptococcal strain Streptococcus equisimilis H46A or the nephritis-associated streptokinase gene (ska1) from th...

AIMS The dosage of fibrinolytic agents such as streptokinase must be controlled carefully to maximize therapeutic activity while avoiding adverse effects. Therefore, the integrity and activity of streptokinase products is likely to be clinically relevant. This study was conducted to compare the in vitro characteristics of different streptokinase preparations. METHODS AND RESULTS Sixteen strep...

Streptokinases secreted by nonhuman isolates of group C streptococci (Streptococcus equi, S. equisimilis, and S. zooepidemicus) have been shown to bind to different mammalian plasminogens but exhibit preferential plasminogen activity. The streptokinase genes from S. equisimilis strains which activated either equine or porcine plasminogen were cloned, sequenced, and expressed in Escherichia coli...

The Western Washington Intravenous Streptokinase Trial randomized 368 patients with acute myocardial infarction to receive either intravenous streptokinase or standard therapy. The ventriculograms and coronary angiograms obtained in 170 patients 10.4 +/- 7.4 days after infarction were analyzed to evaluate the effects of thrombolytic therapy on global and regional systolic function. Streptokinas...
