The implementation of prophylaxis with regular factor VIII (FVIII) replacement for patients with hemophilia radically changed the clinical presentation of this condition, from a disease characterized by progressive disabling musculoskeletal complications, to one compatible with an active and virtually normal lifestyle. In Brazil, although most adults with severe hemophilia still suffer the impa...

The venoms from central Asian snakes (Echis carinatus, Echis multisquamatus, Vipera ursini, Vipera lebetina, Agkistrodon halys halys and Naja naja oxiana) contain several enzymes with amidolytic- and procoagulant activity. We have characterized the activities and the mol. wts of the venom enzymes that are able to convert a number of commercially available chromogenic substrates for activated co...

HERBERT S. SLSE, JACQUES GAUTHIEB, ROBERT BECKER AND JOHN Boz. c n H EMORRHAGE has been an important and ominous sign in victims of irradiation effects. Although its occurrence coincided with a period of intense thrombocytopenia, Allen and Jacobson1 in experimental observations in dogs observed a circulating heparin-like anticoagulant, and Allen2 concluded that it played an important role in th...

BACKGROUND Type 2 diabetic mellitus patients are amongst the most susceptible groups to vascular abnormalities, which predominantly lead to myocardial disease. The hypercoagulable state has been widely studied by researchers as being the major suspicious mechanism facilitating the consecutive chain of molecular events leading to these complications. However, there is no consensus on the definit...

The role of coagulation factors in diabetic retinopathy was studied in non-insulin-dependent diabetic patients. Patients with retionopathy had higher levels of beta thromboglobulin, von Willebrand factor and fibrinogen levels compared to diabetics without retinopathy and controls. Serum magnesium levels were not significantly different between the groups studied. The role of coagulation factors...

Tissue factor (TF) plays a role in thrombogenesis. TF initiates blood coagulation resulting in the generation of protease coagulant mediators (FVIIa, FXa, and FIIa) and fibrin production. TF hypercoagulablility directly contributes to thrombus formation resulting from the major events of fibrin deposition and FIIa-induced platelet activation/aggregation. In addition, blood coagulation indirectl...

Soy protein favorably alters serum lipids and lipoproteins in hypercholesterolemic individuals, thereby reducing cardiovascular disease risk. The primary purpose was to determine the effect of soy protein (40 g/d) on circulating lipids and lipoproteins or coagulation and fibrinolytic factors in normocholesterolemic and mildly hypercholesterolemic perimenopausal women. We also determined the con...

Snake venom serine proteinases affect many steps of the blood coagulation cascade. Each of them usually acts selectively on one coagulation factor. They are therefore potentially useful components to study the mechanisms of action, the regulation and the structure-function relationships of human serine proteinase coagulation factors. This strategy is illustrated for a plasminogen activator puri...

• For the past fift3 j-ears investigators have attempted to show a relationship between high lipid diets and the production of atherosclerosis and thrombosis. Recently interest has shifted from a consideration of diets in the pathogenesis of atherosclerosis to a study of their association with alterations in the levels of coagulation factors as a possible cause of thrombus formation, a possibil...
