The risk of bleeding associated with intracoronary infusion of streptokinase in acute myocardial infarction was determined in a randomised controlled trial containing 302 patients under the age of 70. Intracoronary streptokinase infusion was given to 152 patients and 150 patients were treated conventionally. Bleeding was seen in 24 (16%) patients in the streptokinase group and in two of the con...

Streptokinase, an extracellular protein produced by Streptococci, is capable of activating the human fibrinolytic zymogen plasminogen. The rate of amidolytic activity of the plasminogen-streptokinase complex is greatly diminished by micromolar concentrations of ATP and heparin oligosaccharides. In addition, the plasminogen activator activity of the plasminogen-streptokinase complex is also inhi...

direct regenerations by using mature cotyledonary node as a explants has been shown to be time-saving and convenient strategy for micropropagation of soybean. so we have evaluated regeneration protocol through single shoot using cotyledonary node as a rapid and efficient protocol for two soybean cultivars and one mutant line. cotyledonary nodes explants obtained from 7-days-old in vitro seedlin...

BACKGROUND AND PURPOSE Hemorrhagic transformation (HT) is the most critical complication of thrombolytics in clinical trials in acute stroke. The aim of this study was to determine the rates and the predictors of HT in the Multicenter Acute Stroke Trial-Europe (MAST-E) study. METHODS We performed a post hoc analysis of MAST-E data designed to assess the safety and efficacy of streptokinase ad...

Group A streptococcal infections are sometimes followed by the inflammatory kidney disease acute post-streptococcal glomerulonephritis (APSGN). To test the importance of streptokinase in the pathogenesis of this disease, isogenic strains of the nephritis isolate NZ131, differing only in the ability to produce streptokinase of the nephritis-associated ska1 genotype, were used for infection in a ...

Reactions between purified plasminogen and streptokinase, labelled with (131)I and (125)I respectively, were investigated by polyacrylamide-gel discontinuous electrophoresis. A molecular complex consisting of both (131)I-labelled plasminogen and (125)I-labelled streptokinase migrated between plasminogen and streptokinase. This complex contained bovine plasminogen activator activity. The relativ...

OBJECTIVE (a) To develop an assay for streptokinase resistance. (b) To determine the prevalence of streptokinase resistance in patients presenting with acute myocardial infarction for the first time. (c) To determine the prevalence of streptokinase resistance in patients after exposure to streptokinase or streptococcal infection. DESIGN Open, prospective. PATIENTS 30 healthy volunteers. 40 ...

Streptokinase is an extracellular protein, extracted from certain strains of beta hemolytic streptococcus. It is a non-protease plasminogen activator that activates plasminogen to plasmin, the enzyme that degrades fibrin cloth through its specific lysine binding site; it is used therefore as a drug in thrombolytic therapy. The rate of bacterial growth and streptokinase production was studied in...

The efficacy of intracoronary urokinase and streptokinase were compared in 80 patients with acute myocardial infarction in a prospective, randomized, double-blind study. Urokinase was infused into the occluded coronary artery at 6000 U/min, and streptokinase was infused at 2000 U/min. Maximal duration of infusion was 2 hr. The frequency of successfully opening the artery was similar for patient...
