Extracellular histones promote platelet aggregation and thrombosis; this is followed by induction of coagulation disorder, which results in exhaustion of coagulation factors. Complement component 5 (C5) is known to be associated with platelet aggregation and coagulation system activation. To date, the pathological mechanism underlying liver injury has remained unclear. Here, we investigated whe...
Our knowledge of the blood coagulation system has expanded tremendously in the last 60 years. Many of the coagulation factors were identified through the detailed study of individual patients with a clear hereditary bleeding tendency. However, it became apparent by the mid-1950s that a unified nomenclature was desirable because many of the coagulation factors had been named independently by sev...
New Zealand white rabbits were given 30 ml of goat serum intravenously. This procedure resulted in an immediate decrease in platelet count, fibrinogen, and levels of coagulation factors II, V, VII, and X, due to consumption coagulopathy. These factors returned toward baseline levels approximately 12 hr after the injection. Plasma from rabbits who had received goat serum 48 hr previously (donor ...
Development of antithrombin antibodies following surgery in patients with prosthetic cardiac valves.
Although antibody inhibitors directed against blood coagulation factors are well known, antibody inhibitors directed against thrombin are rare. We describe three postsurgical patients with prosthetic cardiac valves who developed serum autoantibodies reactive with human and bovine thrombin, as demonstrated by coagulation studies and immunoblotting. Despite marked prolongation of the thrombin tim...
• Previous studies in this laboratory have indicated that a combination of systemic hypercoagulability and retarded blood flow is capable of producing a red thrombus in the veins of animals. The hypothesis has been proposed that activation of the procoagulants involved in the formation of intrinsic thromboplastin produces massive thrombosis in large vessels in areas of markedly reduced blood fl...
