Rabbits were injected with sedimented human blood thromboplastin, and
two animals developed serum activity against human blood thromboplastin
in significant excess over naturally occurring inhibitor. This antithromboplastic
activity was specific against human reagent, failed to affect thromboplastin
precursors and had no activity against tissue thromboplastin.
