background: streptokinase is a potent activator of plasminogen to plasmin, the enzyme that can solubilize the fibrin network in blood clots. streptokinase is currently used in clinical medicine as a thrombolytic agent. it is naturally secreted by β-hemolytic streptococci. methods: to reach an efficient method of purification, an immunoaffinity chromatography method was developed that could puri...

background : immunogenicity of streptokinase (stk), as a thrombolytic drug, have limited its clinical use. elimination of the amino acid residues that are responsible for immunogenicity while don’t affect the bioactivity of stk is worthy. recently, we modified the stk through elimination of 42 amino acids from its’ c-terminal and assessed its bioactivity in vitro . objective : in this study, bi...

BACKGROUND Many trials have been done to compare primary percutaneous transluminal coronary angioplasty (PTCA) with thrombolytic therapy for acute ST-segment elevation myocardial infarction (AMI). Our aim was to look at the combined results of these trials and to ascertain which reperfusion therapy is most effective. METHODS We did a search of published work and identified 23 trials, which to...

Introduction: Thromobolysis remains the mainstay in treatment of ischaemic cerebrovascular stroke, haemodynamically significant pulmonary embolism, and retains a role in the treatment of myocardial infarction in hospitals that do not provide emergency percutaneous transluminal angioplasty. Biochemo-mechanical mechanisms of thrombolysis are not yet entirely understood. In the literature, it is b...

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 125l-fibrinlabeled thrombi in rabbit jugular veins at different times after a bolus injection of the fibrinolytic agents. T...

BACKGROUND Treatment of cerebral sinus thrombosis with thrombolytics has been reported in cases with a deteriorating clinical course despite anticoagulant therapy. The rationale of this treatment is to promote rapid recanalisation of the occluded sinus. OBJECTIVES To review the available evidence on the efficacy and safety of thrombolysis in confirmed cerebral sinus thrombosis. SEARCH STRAT...
