background:: hypercoagulability has been reported in primary brain tumors which can lead to thrombotic complications.hydroxyethyl starch (hetastarch) is a synthetic colloid solution with adverse effects on blood coagulation. the aim of this study was to evaluate the protective effect of hetastarch in reducing thromboembolic events in these patients. materials and methods: in a double-blinded cl...
sodium salt of n-acetyl-dl-tryptophan (at) and octanoic acid (caprylic acid ca) individually and in combination were studied as thermal stabilizer with different concentrations in heat treatment of human albumin solution. hplc protein profiles before pasteurization of albumin showed less than 1% polymer. in free stabilizer albumin solution during pasteurization visible clot was formed. but by u...
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...
In this study the rheology of blood clot is measured with the help of rotational rheometer. Several shear strain (0.5, 1 and 2%) are applied with two frequencies (5 and 10 Hz) from the incipient time of clot formation and the response of the sample is measured with the form of shear stress and the phase lag which is interpreted with storage and loss moduli. In this study the ratio of loss to st...
Introduction: Myocardial infarction as a leading cause of death in most populations is associated with blood clot formation in coronary artery, and rapid clot lysis is important for patient treatment. Some reports have indicated the effects of some trace elements on blood coagulation and clot lysis. The aim of this study was to evaluate the effects of zinc, copper and aluminum on in-vitro coagu...

Hemostasis is the process of blood clot formation and represents a coordinated response to vessel injury. It requires an orchestrated response from platelets, the clotting cascade, blood vessel endothelium, and fibrinolysis. Thrombin-stimulated clot formation and plasmin-induced clot lysis are closely related and regulated. This dynamic process is often viewed in phases: formation of a platelet...
