摘要:
Increased fibrinogen yields are obtained by adding a precipitating agent to plasma having a high platelet concentration, such as platelet rich plasma. The precipitating agent may be any of several known agents, including polyethylene glycol and ammonium sulfate. The platelet rich plasma is obtained in the preferred embodiment by subjecting plasma to "soft spin" centrifugation of about 580G. An automatic, multiple decanting and multiple-speed centrifuge is preferably used to separate anti-coagulated whole blood into the platelet rich plasma component and red blood cells. The proteins, preferably fibrinogen, FXIII, and FVIII, in the platelet rich component are precipitated, and the proteins and platelets are then concentrated by further centrifugation.
摘要:
A depot formulation comprising fibronectin or a fragment thereof, a growth factor binding agent linked thereto and growth factor bound to the binding agent is used to promote wound healing in combination with macroscopically oriented cell adhesion proteins, the depot formulations allow the healing process to be directed to afford stronger or more cosmetically acceptable results.
摘要:
This invention provides a fibrin sealant bandage or dressing, wherein said fibrin sealant may be supplemented with at least one composition selected from, for example, one or more regulatory compounds, antibody, antimicrobial compositions, analgesics, anticoagulants, antiproliferatives, anti-inflammatory compounds, cytokines, cytotoxins, drugs, growth factors, interferons, hormones, lipids, demineralized bone or bone morphogenetic proteins, cartilage inducing factors, oligonucleotides, polymers, polysaccharides, polypeptides, protease inhibitors, vasoconstrictors or vasodilators, vitamins, minerals, stabilizers and the like. Also disclosed are methods of preparing and/or using the unsupplemented or supplemented fibrin sealant bandage or dressing.
摘要:
Ein versprühbares Präparat zur akzelerierten Hämostase und optimierten biochemischen Regelung des Wundverschlusses enthält ein Pulvergemisch aus 15 bis 60 Gew.- % Thrombin, 5 bis 80 Gew.-% Trockenhalte- und Stabilisierungsmittel, nämlich Albumin, Globulin und/oder Fibrrinogen, und 1 bis 10 Gew.-% Fibrinolyse-Inhibitor. Das Pulvergemisch ist in einem niedrig siedenden, wasserfreien, als Treibmittel dienendem Lösungsmittel suspendiert. Zum Wundverschluß bzw. zur Wundabdeckung wird ein Sprühstrahl dieser Suspension unter Verdampfung des Lösungsmittels auf die Wunde gerichtet, so daß im wesentlichen nur das trockene, feste Pulvergemisch auf die Wunde gelangt.
摘要:
Ein Präparat zur akzelerierten Hämostase und optimierten biochemischen Regelung des Wundverschlusses («Gewebeklebstoff») besteht lediglich aus festen, pulverförmigen, biologisch aktiven Bestandteilen und enthält 60 bis 96 Gew.-% Fibrinogen, das weitgehend von kälteunlöslichem Globulin befreit ist, 0,05 bis 5 Gew.-% Fibrinolyse-Inhibitor und 0,1 bis 15 Gew.-% Thrombin und/oder Prothrombin. Zur Anwendung kann dieses angereicherte Plasmaderivat unmittelbar und direkt in Form eines trockenen, pulverförmigen Gemisches auf der Wunde bzw. im Operationsgebiet appliziert werden. Weitere Applikationsmethoden sehen das Verstäuben, Versprühen oder Verschäumen des Pulvergemisches mittels eines Treibmittels vor.
摘要:
The present invention provides a composition, comprising: proaccelerin (factor V) and at least one factor selected from the group consisting of: prothrombin (factor II), proconvertin (factor VII), and Stuart-Prower factor (factor X), wherein an amount of the proaccelerin in the composition is between 75% to 750% compared to an amount of proaccelerin in a blood plasma, and wherein an amount of the at least one factor is from 150% to 3000% compared to an amount of the at least one factor in the blood plasma; wherein the amount of proaccelerin and the at least one factor in the composition is determined by extrapolating an observed activity of the composition at a concentration of 500mM NaCl, using a prothrombin complementation assay using a standard curve constructed using the blood plasma.
