Abstract：
:An abnormal prothrombin has been detected in a 26-year-old female, who had no history of excessive bleeding. Prothrombin activity was approximately 10% when measured using either the classical one-stage assay or the assay with Echis carinatus venom, whereas prothrombin antigen level was normal. In keeping with current nomenclature practices, the abnormal prothrombin was designated "Prothrombin Himi". The electrophoretic behavior and calcium binding properties of Prothrombin Himi did not differ significantly from normal. Prothrombin Himi was isolated by chromatography on Q-Sepharose. Electrophoretic migration of the purified abnormal prothrombin on SDS-PAGE was normal. Upon prothrombin activation by Echis carinatus venom, the clotting activity produced from Prothrombin Himi was only 37% of the normal level after 90 minutes of the activation time, where as the amidolytic activity was almost the same as normal. The cleavage patterns of Prothrombin Himi by factor Xa or Echis carinatus venom investigated by SDS-PAGE, were found to be normal. These results indicate that Prothrombin Himi was characterized by a defective thrombin enzymatic activity.
