Nomenclature of exogenous hemostatic factors [letter]

Nomenclature of exogenous hemostatic factors.

The Subcommittee on Exogenous Hemostatic Factors of the Scientific and Standardization Committee of the International Society on Thrombosis and Haemostasis have devised a scheme for coining trivial names for factors that naturally occur outside of the normal hemostatic systems of the blood (coagulation and platelet actions) and either promote or inhibit these systems.' Specifically, the Subcomm...

Classification and Nomenclature of Prothrombin Activators Isolated from Snake Venoms - On behalf of the Registry of Exogenous Hemostatic Factors of the Scientific and Standardization. Committee of the ISTH

Several prothrombin activators from snake venoms have been isolated and characterized (For details, see 1). Initially, they were classified into three major groups based on their structural and functional properties (1, 2). They differ from each other in their cofactor requirements and the products formed. Group I activators are metalloproteinases. They convert prothrombin to meizothrombin and ...

Nomenclature for blood clotting factors.

Measurement of hemostatic factors in EDTA plasma.

This study determined whether immunoassays of factors VII (FVII) and VIII (FVIII) and von Willebrand factor (vWF) in EDTA-anticoagulated plasma samples are comparable to bioassays and immunoassays of these factors in citrate-anticoagulated plasma. Blood from 40 healthy volunteers was collected in EDTA- and citrate-anticoagulant tubes and assayed using immunoassays (EDTA and citrate) and clottin...

Hemostatic risk factors in ischemic stroke.

The role played by hemostasis in the pathogenesis of ischemic stroke is still controversial. In the present study, we looked for a possible association of ischemic stroke and high clotting activity of factor II (FII:C), factor V (FV:C), factor VII (FVII:C), factor X (FX:C) and fibrinogen. We investigated 157 non-anti-coagulated patients (86 males, 71 females; median age 41 y, range 16-73 ), who...
