    摘要: This invention provides a method for inhibiting thrombosis in a patient whose blood is subjected to extracorporeal blood circulation which comprises contacting the extracorporeal circulating blood with a Factor IXa compound in an amount effective to inhibit thrombosis in the blood of a patient and under conditions such that the Factor IXa compound circulates in the patient. The Factor IXa compound may include an active site-blocked Factor IXa compound or Glu-Gly-Arg chloromethyl ketone-inactivated human factor IXa compound. This invention also provides that the effective amount may be from about 0.1 &mgr;g/ml plasma to about 250 &mgr;g/ml plasma or from about 0.5 &mgr;g/ml plasma to about 25 &mgr;g/ml plasma. The patient may be subjected to extracorporeal blood circulation during transplant surgery or cardiopulmonary bypass surgery. This invention further provides for a method for inhibiting thrombosis in a patient whose blood is subjected to extracorporeal blood circulation, which comprises contacting the extracorporeal circulating blood with an agent capable of inhibiting a step of the intrinsic pathway of coagulation in an amount effective to inhibit thrombosis in the blood of a patient and under conditions such that the Factor IXa compound circulates in the patient. The agent may be an active site-blocked Factor XII compound or an active site-blocked Factor XI compound.

    摘要: This invention provides an assay to monitor antithrombic activity of a Factor IXa compound infused into circulation of a patient which includes: (a) obtaining Factor IXa-deficient plasma; (b) mixing the plasma from step (a) with diatomaceous and with plasma from the patient; (c) incubating the mixture with a source of lipid and calcium chloride under conditions suitable for clot formation; and (d) measuring time necessary for clot formation in the incubate, thereby monitoring the antithrombic activity of the Factor IXa compound infused into the circulation of the patient.
