Abstract:
A description is given of a one-component tissue adhesive containing, in aqueous solution, fibrinogen, F XIII, a thrombin inhibitor, prothrombin factors, calcium ions and, where appropriate, a plasmin inhibitor and of a process for the production thereof.This adhesive can be reconstituted from a freeze-dried form with water. It can contain all active substances in pasteurized form and is then free of the risk of transmission of hepatitis and HTLV III.
Abstract:
A process for purifying liquids containing blood clotting factors by adsorption of the factors on mineral adsorbents such as calcium phosphate, aluminum hydroxide gel, barium sulfate or hydroxylapatite in the presence of calcium ions followed by elution is described.
Abstract:
What is disclosed is a plastics material adaptable to biomedical uses, the surface of which material at least partially consists of a graft copolymer having a hydrocarbon main chain and side chains grafted thereon, said side chains being polymers comprising at least one vinyl monomer selected from the group consisting of acrylic acid esters of the formulaCF.sub.3 --(CF.sub.2).sub.x --(CH.sub.2).sub.y --O--CO--CH.dbd.CH.sub.2,where x is an integer from 3 to 16 and y is an integer from 1 to 12, vinylene carbonate, N-vinyl alkylamides of the formula ##STR1## wherein R.sup.1 and R.sup.2 are the same or different and each is hydrogen or alkyl having 1 to 6 carbon atoms.
Abstract:
A process for the preparation of a concentrate of von Willebrand factor is described, entailing a solution of a complex of this factor with factor VIII:C being optionally pasteurized and treated with an anion exchanger, there being no binding of the von Willebrand factor.
Abstract:
The disclosed invention provides a method for determining the plasminogen activator (PA) activity in a biological fluid. The method involves the use of proteolytically-degraded plasminogen and effectively eliminates the influence of alpha-2-antiplasmin on the determination of PA activity.
Abstract:
A method and an agent for the functional determination of protein C inhibitor in body fluids are described, in which this fluid is incubated with a known amount of a plasminogen activator, fibrinogen and a sulfated carbohydrate, and the residual activity of the plasminogen activator is determined, and from this the amount of protein C inhibitor is determined.
Abstract:
A process for the pasteurization of antihemophilic cryoprecipitate (AHC) is described, wherein AHC is heated in the presence of calicum ions, an amino acid and a carbohydrate. The pasteurized AHC is used for the treatment of coagulation disturbances.
Abstract:
What is disclosed is a process for rendering plasminogen virtually free of hepatitis virus by heating a plasminogen solution in the presence of a proteinase inhibitor with plasmin specificity, an amino acid, and a saccharide or sugar alcohol.
Abstract:
What is disclosed is a method for making a preparation containing blood clotting Factors IX and/or X virtually hepatitis-safe by warming said peparation in the presence of calcium ions and in the further presence of an amino acid and/or a saccharide or sugar alcohol.
Abstract:
What is disclosed is a method for treating a preparation containing blood clotting Factors II and/or VII to render it virtually hepatitis-free by warming said preparation in the presence of a chelating agent and in the further presence of an amino acid and/or a saccharide or sugar alcohol.
