  • Publication number: 20100034746
    Abstract: The present invention relates to a method for evaluating a test compound for antithrombotic activity, thrombolytic activity, or a combination thereof. This method can include providing or employing a donor test animal and a recipient test animal. The donor and recipient test animals can have been pretreated with test compound. The donor test animal can be configured to provide oxygenated blood to the recipient test animal through a thrombus inducing system. This method also includes initiating transport of blood from the donor test animal to the recipient test animal through the thrombus inducing system. The method can include interrupting respiration of the recipient test animal and determining the length of time that the recipient test animal survives. In this method, a survival time longer than a predetermined threshold time indicates that the test compound has antithrombotic activity, thrombolytic activity, or a combination thereof.
