title: [Thromboplastin activity of extracts of human thyroid glands (author's transl)].
abstract: Aqueous extracts of thyroid glands were prepared from 25 surgical specimens of 19 patients. The average prothrombin time of sixteen 3:4 diluted extracts of thyroids from 13 euthyroid patients was 16.8 +/- 2.3 sec as measured with 100% human plasma. Under similar conditions the average prothrombin time of extracts obtained from the grey matter of three human brains was 18.4 +/- 0.3 sec. The thyroid may thus be considered as an organ containing one of the highest concentrations of tissue thromboplastin.
