background: we sought to evaluate the efficacy and safety of the different trade forms of streptokinase available in our country, namely heberkinasa (heberbiotec, havana, cuba) and streptase (aventis behring gmbh, marburg, germany). methods: we conducted a double-blind randomized clinical trial to compare the two streptokinase formulations, i.e. heberkinasa (hbk) or streptase (stp), in patients...

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...

Objective: The present study is aimed to investigate in vitro thrombolytic activity of three Bangladeshi medicinal plants Averrhoa bilimbi (Oxalidiaceae), Clerodendrum viscosum (Verbanaceae) and Drynaria quercifolia (Polypodiaceae).

BACKGROUND The benefit of intravenous thrombolytic therapy in elderly patients with myocardial infarction is uncertain. There are no randomized trials of thrombolytic efficacy or observational studies of clinical effectiveness that focus specifically on the elderly. METHODS AND RESULTS To determine whether thrombolytic therapy for elderly patients is associated with a survival advantage in a ...

Limitations of CT Angiography in Patient Selection for Thrombolytic Therapy To the Editor: We have read with great interest the article by Wildermuth et al1 on the role of CT angiography (CTA) in patient selection for thrombolytic therapy. The authors report that selection of patients with little potential for benefit from thrombolytic therapy is feasible with the use of CTA. The CTA findings, ...
