abstract  introduction: during extrinsic coagulation pathway, a complex is developed between factor vii, calcium and tissue factor (a cell membrane lipoprotein that is exposed after cell injury). factor vii needs calcium and vitamin k for its biologic activation. coronary artery disease (cad) can be induced by increased level and activity of the coagulation factors vii, viii and ix. in postmeno...

Acquired coagulation factor inhibitor is a rare coagulation disorder. We herein report a patient with acquired factor V inhibitor showing a decrease in multiple coagulation factor activities. A high titer of factor V inhibitor presumably led to a marked inhibition of factor V activity in the specific factor-deficient plasma used in coagulation factor activity assays based on either an activated...

Warfarin is the most widely used medicine for oral anticoagulant therapy (OAT). It inhibits the synthesis of coagulation factors II, VII, IX, and X in the liver and results in the production of inactive or partially active versions of these factors. Inactive coagulation factors interfere with prothrombin time measurement (Quick and Owren PT) measuring the sum of coagulation activity and inhibit...

multiple sclerosis (ms) is a neuroinflammatory autoimmune disease which mediated by various molecular and cellular immune components however recent reports have shown that coagulation factors that traditionally separate from the immune system might also be involved in ms development and progression.studies on experimental autoimmune encephalomyelitis (eae) and human ms patients reports alterati...

factor v (fv) deficiency is a rare bleeding disorder (rbd) that inherit in autosomal recessive manner. diagnosis of fv deficiency (fvd) is made by routine coagulation tests, fv activity and molecular analysis. in patients with fvd, routine coagulation tests including activated partial thromboplastin time (aptt), prothrombin time (pt) and evenbleeding time (bt) are prolongedwhile thrombin time (...

Platelet aggregation inhibitory effect and anticoagulant properties of fractions separated from the venoms of Cerastes persicus fieldi and Echis carinatus were investigated. The partial fractionation was performed on a Sephadex G-100 column. Two fractions separated from Cerastes persicus fieldi showed anti platelet aggregation activity on ADP (200 µM)-induced platelet aggregation (ca 80% inhibi...
