    摘要: A method for the determination of urokinase (UK) or tissue plasminogen activator (t-PA) is described, in which the activator is incubated with plasminogen, with a polysulfuric ester of a saccharide or with a sulfated sugar and, where appropriate, fibrin or fibrin degradation products, and the conversion of plasminogen into plasmin is determined, and agents suitable for this method are described.

    摘要: In the preparation of parenteral solutions for the therapy and prophylaxis of thromboses and embolisms, because of the poor solubility of t-PA hitherto either the infusion of very large volumes has been necessary, or else a solution with a low volume and a high t-PA concentration has been prepared at the expense of setting up a non-physiologically low pH of 2 to 5.Hence, the present invention relates to a process for the preparation of a solution of high concentration of a protein having plasminogen activator activity, where an increase in stability and solubility is achieved by adding at least two substances from the group of D- and/or L-amino acids, their salts, derivatives or homologs. This invention also relates to a process for the pasteurization of a protein solution having t-PA activity, and to a t-PA-containing solution prepared by the claimed process, and to the use of this solution as a fibrinolytic in human and veterinary medicine.

    摘要: A process for the production of an unnative and biologically active bonded collagen fiber sheet from human placentae is described, in which process collagen-containing material from placentae is treated with a neutral salt solution, a solution of citric acid and with pepsin. The degraded collagen material obtained in this manner is, where appropriate, treated with a crosslinking agent. The collagen material produced in this manner is used for producing bonded collagen fiber sheets which can be used, for example, as covering for wounds.
