摘要:
Human urine-origin colony-stimulating factor and kallikrein are separated in pure form, respectively, from an aqueous solution thereof, such as a urinary protein-concentrated solution by subjecting the solution added with a stabilizer such as octyl-phenoxypolyethoxyethanaol or polyethylene glycol both having a molecular weight of 1,000-10,000, to high-performance gel filtration effective in molecular exclusive limit of 10.sup.5 -5.times.10.sup.5 as determined with globular protein.
摘要:
An antithrombin preparation, secure and stable for a long period of time, can be obtained by freeze-drying an aqueous solution containing antithrombin-III as main component in the presence of an effective quantity of at least one member selected from the group consisting of proteins, sugars, amino acids, inorganic salts and salts of organic acids as stabilizer.
摘要:
An alkali metal hydrogensulfite or sulfite is effective for controlling a local injury such as inflammation and vein injury occurring on the injection of an antitumor benzodiazepine compound of the formula ##STR1## wherein R.sub.1 denotes hydrogen atom, or acyl, carbamyl, or alkoxycarbonyl group; R.sub.2 denotes hydrogen atom or acyl group; and R.sub.3 denotes sulfinic acid rest, SO.sub.2 X, or sulfonic acid rest, SO.sub.3 X, X meaning hydrogen, alkali metal or alkaline earth metal. An aqueous solution containing the both can be administered by injection.
摘要:
A reagent for determination of human blood coagulation factor XIII for reversed passive hemagglutination reaction which comprises sensitized erythrocytes prepared by sensitizing animal erythrocytes with specific anti-human factor XIII antibody, and a kit using the reagent are disclosed.
摘要:
Physiologically active substances such as antibiotics can preferentially be carried to a morbid part, for example, injured tissue and neoplastic cell proliferation site by administering its complex with fibronectin to repair the morbid part. The complex is prepared by the reaction between the physiologically active substance and the fibronectin with or without intervention of a protein cross-linking agent.
摘要:
A method for stabilizing plasminogen which comprises adding a physiologically acceptable inorganic salt to a plaminogen-containing aqueous solution to give a final concentration of the salt of 0.002 to 0.4 M.
摘要:
New organic dibasic acid half esters of 7-ketocholesterol and of 7-hydroxycholesterol represented by the general formula ##STR1## (wherein R.sub.1 is .dbd.O or --OH and R.sub.2 is a C.sub.1 -C.sub.5 alkylene group or a phenylene group) and physiologically acceptable salts thereof. These compounds are effective as an immunosuppressive or an anti-inflammatory agent.
摘要:
Compounds of the general formula ##STR1## or their salts, esters or amide derivatives; and processes for their preparation. In the formula, R.sub.O represents hydrogen or lower alkyl, R.sub.2 represents hydrogen, halogen or nitro, R.sub.3 represents hydrogen or halogen, and R.sub.4 represents hydrogen or lower alkyl; and when R.sub.O is hydrogen, R.sub.2, R.sub.3 and R.sub.4 are all hydrogens and the group ##STR2## is present at the 2-position. These compounds exhibit superior analgesic and/or anti-inflammatory actions with little gastrointestinal troubles.
摘要:
A dry .gamma.-globulin preparation capable of intravenous injection which is obtainable by polyethylene glycol fractionation of plasma is improved in its water-solubility and stability against increase of anticomplement activity and decrease of antibody titer by purifying the .gamma.-globulin fraction with respect to protein to render the residual polyethylene glycol substantially not detectable in its 5% W/V solution, adding 0.2 to 2 parts by weight of glucose based on 1 part of .gamma.-globulin, and lyophilizing its solution.
摘要:
A lyophylized cold insoluble globulin preparation can be prepared in stable condition and in short time by lyophylizing an aqueous solution of a cold insoluble globulin in the presence of albumin and a neutral amino acid, a monosaccharide, a disaccharide or a sugar alcohol. The preparation dissolves in water without occurrence of turbidity and is usable for injection.
