摘要:
A homogeneous suspension, in a buffered aqueous solution having a pH of 7.0 to 7.7, of a destroyed microorganism which is positive to the clumping factor, said suspension containing from 3 to 50 percent by weight of at least one polyhydric alcohol soluble therein, is disclosed, as are its manufacture and its use as a reagent for the determination of fibrinogen and for fibrin cleavage products.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
A process for removing toxins from solutions of proteins, in which an aqueous solution of a protein which contains a buffer substance, a chelating agent and a detergent is subjected to an ion exchange chromatography, is described.
摘要:
The invention relates to a method for the determination of the activity of serine proteases and serine protease inhibitors in plasma or other biological fluids.The only methods hitherto available for rapid and accurate determination of the content of serine proteases or serine protease inhibitors have been very time-consuming and methodologically demanding. In the method according to the invention for the determination of the activity of serine proteases or serine protease inhibitors, specific inhibitors are inactivated by addition of at least one oxidizing agent and, where appropriate, at least one detergent. The addition of an omega-aminocarboxylic acid enhances and observed effects when the serine protease is plasmin.
摘要:
A process for the production of a preparation of blood coagulation factor VIII which makes it possible to obtain a pasteurized product which is virtually free of immunoglobulins, isoagglutinins, fibronectin and coagulable fibrinogen is described.A product of this type can be used for the treatment of blood coagulation disturbances.
摘要:
Process for the manufacture of a collagen solution and its use for the manufacture of collagen fibrillae for adsorbing coagulation factors, as diagnostic agent, for the manufacture of a collagen sponge and for use in a cosmetic preparation.
摘要:
The C1 esterase inhibitor (C1-INH) from human plasma is a sialic-acid-containing glycoprotein which can bind other glycoproteins and glycolipids which may be components or even membrane components of microoganisms of viral and bacterial origin. In accordance with the invention, this binding can inhibit the penetration of certain viruses into target cells.
