  • Patent number: 9884077
    Abstract: An extract from inflamed skins of rabbits inoculated with vaccinia virus is provided where the quality of the extract is more stabilized. A preparation, etc. containing said extract as an active ingredient is also provided. When the amount of sulfated tyrosine contained in an extract from inflamed skins of rabbits inoculated with vaccinia virus and also contained in a preparation containing said extract as an active ingredient is used as an index, the quality of the extract and the preparation among the manufacturing lots can be warranted as a more stabilized one. In the extract from inflamed skins of rabbits inoculated with vaccinia virus and the preparation containing said extract where the quality thereof is more stabilized by such a method, the efficacy and the safety thereof are now guaranteed more strictly resulting in very high usefulness.

  • Publication number: 20140017311
    Abstract: A dried product of an extract from inflammatory rabbit skin inoculated with vaccinia virus having an inhibitory activity for the production of a kallikrein-like substance is produced by admixing the extract with a saccharide, sugar alcohol or ascorbic acid before reaching dryness, and then drying the admixture to a solid form such as granules. The dried product may be employed to produce a solid preparation for oral administration, such as tablets, having an inhibitory activity for the production of a kallikrein-like substance.

  • Patent number: 6117648
    Abstract: Blood coagulation factor XII (FXII) is activated using a receptor for globular heads of the complement component Clq. The receptor (gC1qr) is a protein and provides a more faithful in vitro reproduction of the actual FX-II-activating reaction which occurs in living organisms. The protein receptor, gClqR may be obtained in at least substantially pure or isolated form by recombinant genetic engineering techniques or by isolation from animal cell membranes to which the complement component Clq binds. The receptor may be separated, purified, or isolated from cell membranes. The activation of the blood coagulation factor XII may be conducted in: 1) an animal plasma, 2) a reconstituted plasma kallikrein-kinin system, or 3) an at least substantially pure blood coagulation factor XII. The activation with the receptor is preferably conducted in the presence of zinc ions.
