  • Patent number: 5675058
    Abstract: An in vivo assay for determining the potential thrombogenic activity of a test compound entails pre-treating an animal with both a hepatoxin and either a bacterial agent (whole bacteria or bacterial toxins, including endotoxins) or a bacterial agent-induced cytokine, which pre-treatment enhances sensitivity to thrombogenic substances. The sensitized animal can be used in identifying a thrombogenic substance even when it is a weak potentiator of thrombogenesis, and in detecting smaller amounts of a strong potentiator.

  • Patent number: 5597800
    Abstract: A treatment of ischemia and the attendant reperfusion injury entails the administration plasmin and plasmin-forming proteins, including lys-plasminogen and similar substances. Lys-plasminogen, which can be obtained from the proteolytic cleavage of glu-plasminogen, has been found to have a protective effect on tissue that has been injured by ischemic conditions. The administration of lys-plasminogen alone, in a dosage of about 10-1000 caseinolytic units/kg, can be used to treat subjects during the time of reperfusion and after reperfusion has already occurred. Lys-plasminogen also can be administered in conjunction with clot lysis therapies, such as those that employ tissue plasminogen activator and the like. Lys-plasminogen can also lessen cerebral edema which results from cerebral ischemia.
