Modern Conceptions of Blood Clotting

Modern Conceptions of Blood Clotting.*

DESPITE the large number of researches which have been made on blood coagulation, no single one of the many theories advanced satisfies the criterion of a tenable hypothesis in which all known facts should be correlated. A better understanding of the fluidity and clotting of blood should lead to important results. On the practical side, we may hope for the elucidation of thrombosis—the formatio...

Proteases in blood clotting.

The serine proteases, cofactors and cell-receptor molecules that comprise the haemostatic mechanism are highly conserved modular proteins that have evolved to participate in biochemical reactions in blood coagulation, anticoagulation and fibrinolysis. Blood coagulation is initiated by exposure of tissue factor, which forms a complex with factor VIIa and factor X, which results in the generation...

Blood Clotting Enzymology

Dr. Nelson is an endoscopist, and his technique involves introducing a small Geiger counter through an esophagoscope (or sigmoidoscope) and recording counting rates over the surface of the organ being examined in a patient who has received 500 uc. Of p32 the day before the exam. A positive result is obtained when a clear increase in counting rate is observed at some area as the counter is moved...
