Antithrombin-independent effects of heparins on fibrin clot nanostructure.
OBJECTIVE Because of the widespread clinical use of heparins, their effects on the enzymatic cascade are very well known. In contrast, little is known about the direct effect of heparins on the nanostructure of fibrin fibers, even though this nanostructure plays a major role in the mechanical strength and lysis of clots. This lack of reliable data can be correlated with the lack of a nonintrusi...
متن کاملKinetics of fibrin clot lysis.
The principles relating the lysis times of fibrin clots to their contents of fibrin, plasminogen and plasminogen-activator were investigated. Mathematical considerations suggested that the square of the lysis time should correlate linearly with the fibrin content, and inversely with the activator and the plasminogen contents of the system. Experimental studies, during which these parameters wer...
متن کاملPolyphosphate enhances fibrin clot structure.
Polyphosphate, a linear polymer of inorganic phosphate, is present in platelet dense granules and is secreted on platelet activation. We recently reported that polyphosphate is a potent hemostatic regulator, serving to activate the contact pathway of blood clotting and accelerate factor V activation. Because polyphosphate did not alter thrombin clotting times, it appeared to exert all its proco...
متن کاملIdentification of Fibrin Clot-Bound Plasma Proteins
Several proteins are known to bind to a fibrin network and to change clot properties or function. In this study we aimed to get an overview of fibrin clot-bound plasma proteins. A plasma clot was formed by adding thrombin, CaCl(2) and aprotinin to citrated platelet-poor plasma and unbound proteins were washed away with Tris-buffered saline. Non-covalently bound proteins were extracted, separate...
متن کاملGamma globulin inhibition of fibrin clot formation.
Myeloma gamma globulins have been reported to interfere with fibrinogen-fibrin conversion. A patient with multiple myeloma is described with a gamma globulin IgG1lambda concentration of 11 g per dl, prolonged thrombin time and poor clot retraction. Purified gamma globulin from the patient's serum and from normal serum caused prolongation of the thrombin time and reptilase clotting time assays i...
