From September 1962 to May 1972 145 patients with acute or subacute deep vein thrombosis confirmed by phlebography were treated with streptokinase. During the same period 42 patients considered unfit for thrombolytic therapy were treated with herapin and oral anticoagulants. The results, assessed by repeat phlebography, in 93 of the patients treated with streptokinase were compared with those i...

BACKGROUND To establish a relation between the survival rate of island skin flaps submitted to prolonged ischemia and the effect of streptokinase and allopurinol administered after the ischemic period. METHODS A total of 48 male Winstar rats, each weighing between 300 and 350 grams,were separated into four groups of twelve as follows: control, allopurinol, streptokinase and association of all...

BACKGROUND Standard treatment for pleural infection includes catheter drainage and antibiotics. Tube drainage often fails if the fluid is loculated by fibrinous adhesions when surgical drainage is needed. Streptokinase may aid the process of pleural drainage, but there have been no controlled trials to assess its efficacy. METHODS Twenty four patients with infected community acquired parapneu...

In early diagnosis of typhoid fever, the emphasis has for long been on the isolation of S. typhi from blood culture. Clot culture techniques have not enjoyed the same vogue, although they are largely used in areas where the disease is endemic. Felix (1924) found that clot culture was hardly ever unsuccessful if blood culture was successful, but that the reverse was frequently true. He attribute...

BACKGROUND Thrombolytic therapy in patients with acute myocardial infarction (AMI) is hampered by procoagulant effects. In vitro studies have indicated that plasmin stimulation activates the kallikrein-contact-phase system, resulting in thrombin activation. This prospective comparative study was designed to examine the procoagulant effects of streptokinase or alteplase in AMI. METHODS AND RES...

Streptokinase is a virulence factor of streptococci and acts as a plasminogen activator to generate the serine protease plasmin which promotes bacterial metastasis. Streptokinase isolated from group C streptococci has been used therapeutically as a thrombolytic agent for many years and its mechanism of action has been extensively studied. However, group A streptococci are associated with invasi...

INTRODUCTION Usage of fibrinolytic therapy leads to reperfusion of the occluded coronary arteries, rescue of ventricle myocardium and successful recovery of patient. GOAL The objective of this study was to compare the reperfusion effect of streptokinase and alteplase in acute myocardial infarction (AMI) by analyzing echocardiographic parameters and post-coronarography treatment. PATIENTS AN...

Genomic DNA from Streptococcus equisimilis strain H46A was cloned in Escherichia coli by using the bacteriophage lambda replacement vector L47 and an in vitro packaging system. A casein/plasminogen overlay technique was used to screen the phage bank for recombinants carrying the streptokinase gene ( skc ). The gene was present with a frequency of 1 in 836 recombinants, and 10 independent clones...

patients treated with streptokinase, one of seven treated with Arvin, and two of seven given heparin. Streptokinase was shown to cause extensive dissolution of thrombi in all but two of the 12 patients studied, sometimes within 12 hours but in one patient not until after six days of continuous infusion. Methods and aims of laboratory control were discussed (Kakkar et al, 1969) and the side effe...

Streptokinase is a potent fibrinolytic agent which is widely used in treatment of deep vein thrombosis (DVT), pulmonary embolism (PE) and acute myocardial infarction (MI). Major limitation of this enzyme is its short biological half-life in the blood stream. Our previous report showed that complexing streptokinase with chitosan could be a solution to overcome this limitation. The aim of this re...
