Background/introduction Spontaneous cerebral hemorrhage (ICH) is a major cause of mortality and morbidity worldwide. Although the mechanisms leading to ICH are relatively well known, little improvement in outcomes has occurred over the years, in spite of significant advances in surgical techniques and medical management options. Evidence is available to suggest that liquefying and/or removing t...

Hypofibrinolysis is a risk factor for venous and arterial thrombosis, and can be assessed by using a turbidimetric tPA-induced clot lysis time (CLT) assay. Biological variation in clot lysis time may affect the interpretation and usefulness of CLT as a risk factor for thrombosis. Sufficient information about assay variation and biological variation in CLT is not yet available. Thus, this study ...

The muscle and cytoskeletal protein actin is released from cells as a consequence of cell death and interacts with components of the hemostatic and fibrinolytic systems, including platelets, plasmin, and fibrin. We report here that incorporation of actin filaments into fibrin clots changes their viscoelastic properties by increasing their shear modulus at low deforming stresses and by nearly el...

Tinospora crispa, a plant belonging to the family of Menispermaceae is a well-known traditional medicinal plant used in Bangladesh. The methanolic extracts of stems of the plant were evaluated for their thrombolytic and preliminary cytotoxic activities. The thrombolytic activity was evaluated using the in vitro clot lysis model while while the screening of cytotoxic activity was done using brin...

Recent experiments in vitro have shown that inhibition of human ci2-antiplasmin by a monoclonal antibody (MAb RWR) markedly enhances clot lysis by plasminogen activators. To extend these studies in vivo, we tested whether inhibition of clot or fibrin-bound o2-antiplasmin by MAb RWR could enhance the lysis of a human clot by tissue-type plasminogen activator (t-PA) in a rabbit jugular vein throm...

OBJECTIVES Primary Sjögren's syndrome (pSS) shares clinical features and pathogenetic mechanisms with systemic lupus erythematosus (SLE). SLE is associated with an increased thromboembolic risk; however, it is unclear whether pSS patients are susceptible to thromboembolic diseases. In this study, we examined ex vivo blood clot formation (clot strength, rates of clot formation and lysis) in pSS ...

Delayed splenic rupture, though uncommon, is a recognised clinical condition and is associated with a significant mortality rate. In the vast majority of cases the patient re-presents with abdominal symptoms and/or signs of acute intraperitoneal haemorrhage. A case is presented of delayed splenic rupture presenting with jaundice attributable to intra-abdominal clot lysis.
