[Changes in PT and APTT When Administrating Rivaroxaban, a Direct Inhibitor of Activated Factor X].

The effects of oral rivaroxaban (RX), a direct inhibitor of activated factor X (Xa), on prothrombin time (PT) and activated partial thromboplastin time (APTT) were examined. PT and APTT before and after administration of 15 mg RX in 10 healthy subjects were measured by using various reagents. In addition, the blood Xa inhibitor concentration was measured and its correlation with PT and APTT, as measured by each reagent, was examined.

[Progress in assays for and new developments in autoimmune pathophysioirmen's introductory remarks].

We examined the influence of a revision of health insurance in 2004 in Teikyo University Hospital in comparison with 2003. Out to the returns of most hematological tests, especially HbA1c and TK, being included in the treatment charges of outpatients, gross laboratory test sales decreased more than expected. Increased income from judgment charges and management charges could not make up for the deficit in test sales.
