Blood-clotting Activity of the Venom of Bothrops jararaca
Nature, 1959THE well-known blood-clotting activity of the venom from snakes of various species of the genus Bothrops has been attributed to its proteolytic activity1, although Michl2 (using paper electrophoresis) and Holz and Raudonat3 (using fractional precipitation with ammonium sulphate) have presented evidence against this point of view.

Activation of Bovine Prothrombin as Monitored by the Clotting Assay
Biological Chemistry Hoppe-Seyler, 1990The activation of bovine prothrombin was studied with highly purified clotting factors and using a coagulation assay developed to look at the initial rate of prothrombin conversion as well as the conversion rate over a time course of 75 min. Activation of prothrombin by factor Xa alone was slow.

Influence of Plasmin on the Clotting and Anticlearing Activities of Platelets
Thrombosis and Haemostasis, 1963SummaryPlatelet factor 4 (antiheparin factor) is rapidly destroyed by plasmin. This phenomenon occurs as well in platelet suspensions as in their extracts.Platelet factor 4 is more sensitive to the plasmin action than platelet factor 1. Platelet factor 3 is resistant to the plasmin action.Platelet inhibitor of the clearing reaction is partially ...

Factor VII is a single-chain, vitamin K-dependent glycoprotein of molecular weight 47 000–50 0001–5. Its plasma concentration is about 250–700ng/ml (5–15nmol/L). The complex of the zymogen factor VII with tissue thromboplastin and Ca2+ has been proposed as an efficient activator of factor X7,8 Factor VII can be converted to the two-chain α-VIIa by ...

New Concepts in Activation of the Clotting Cascade in Sepsis
Sepsis, 1999Systemic infection leads to activation of the coagulation system. The presence of endotoxins results in exposure of tissue factor. Tissue factor-mediated initiation of coagulation results in the generation of thrombin for fibrin formation. Thrombin formation continues after fibrin formation via feedback activation of factor XI, thereby propagating the ...

Haemolytic activity in the blood clot of "Aedes aegypti"
Acta tropica, 1975In the present study it was demonstrated that mosquito blood clots contain a haemolytic principle which achieves haemolysis of washed erythrocytes in an isotonic medium. Proteinases are thought to play a role in this process. No final proof could be given for the existence of phospholipase activity although some results suggest the presence of this ...
