We studied thrombolysis in an animal model of embolic stroke to determine the safety of tissue plasminogen activator and streptokinase. We occluded the middle cerebral arteries of 137 rabbits with radiolabeled blood clots and administered tissue plasminogen activator (n=49), streptokinase («=40), or saline (n=48) at various times after embolization. We assessed the rate of thrombolysis and cere...
We investigated the effect of streptokinase on determination of fibrinogen and related clottable proteins in an effort to assess the relative reliability of these determinations in monitoring patients being treated with streptokinase. Citrated plasma was incubated with and without streptokinase, then assayed for fibrinogen (I), fibrin(ogen) degradation products (II), total clottable protein (II...
BACKGROUND Whether and to what extent complement is activated in acute myocardial infarction (AMI) and how it contributes to inflammation of the ischemic area are not yet clear. Fibrinolytic agents used for thrombolysis are known to activate complement in vitro and may contribute to its activation in vivo. The aim of this study was to measure the extent of complement activation in AMI patients,...
Lipoteichoic acid (LTA) from gram-positive bacteria can stimulate monocytes to produce cytokines. To ascertain whether aggregation of LTA receptors can contribute to this effect, human monocytes were sensitized with LTA from Streptococcus pyogenes, washed, and treated with anti-LTA antibodies. The addition of anti-LTA antibodies or F(ab')2 fragments markedly enhanced the aggregation of LTA rece...
A serendipitous discovery by William Smith Tillett in 1933, followed by many years of work with his student Sol Sherry, laid a sound foundation for the use of streptokinase as a thrombolytic agent in the treatment of acute myocardial infarction. The drug found initial clinical application in combating fibrinous pleural exudates, hemothorax, and tuberculous meningitis. In 1958, Sherry and others...
as well as shorter overall hospitalization duration. In a study in 1949, Tillett and Sherry [6] reported the use of a mixture of streptokinase and streptodornase for intrapleural fibrinolysis. Purified streptokinase was available in the 1960s, resulting in an improved safety profile [7]. Due to concerns about the antigenicity of streptokinase, urokinase was introduced in 1987 and became the mos...
The main factors affecting the outcome of Trueperella pyogenes (T. pyogenes) mastitis were examined through a survey of diagnostic data and interviews relating to the occurrence of T. pyogenes mastitis in 83 quarters from 82 Holstein cows between August 2012 and April 2014. Ultimately, one cow was sold during the examination, and 82 quarters from 81 cows were used for analysis on prognosis. T. ...
BACKGROUND Significant morbidity and mortality result from the ineffective evacuation of empyema. Failure of conventional first line treatment with closed intercostal tube drainage and antibiotic therapy may result in fibrin deposition and loculated empyema. Enzymatic debridement using intrapleural instillation of streptokinase is a non-invasive therapeutic option which may obviate the need for...
BACKGROUND As compared with thrombolytic therapy, primary coronary angioplasty results in a higher rate of patency of the infarct-related coronary artery, lower rates of stroke and reinfarction, and higher in-hospital or 30-day survival rates. However, the comparative long-term efficacy of these two approaches has not been carefully studied. METHODS We randomly assigned a total of 395 patient...
Some drugs including streptokinase have been reported to precipitate Guillain-Barré syndrome. We report a 70-year-old man with acute anterior myocardial infarction who developed Guillain-Barré syndrome seven days after thrombolytic therapy with streptokinase.
