摘要:
An automatic analyzer comprising a plurality of sample containers for accommodating different blood samples individually, specific sample container moving means, a plurality of reagent containers for accommodating at least a reagent for an assay of guanase activity, a specific reagent container holding means, a plurality of reaction containers, specific reaction container moving means, specific sample pouring means, specific cleaning vessels, specific stirring means, specific measuring means, specific cleaning means, a specific analog-digital converter, specific counting-calculating means, a specific display means, and specific operation control means, so that the display means produces a signal for excluding the measured blood sample corresponding to a display value when the display value is above a predetermined reference value of guanase activity.
摘要:
The guanase activity in body fluids such as blood serum can be rapidly and accurately assayed by (I) decomposing guanine with the guanase in the specimen to xanthine and ammonia at pH 7-9, preferably at pH 8, (II) decomposing the xanthine formed by former step I with xanthine oxidase to uric acid and hydrogen peroxide, (III) reacting the reactant solution of the former step II with 3-methyl-2-benzothiazolinonehydrazone, an aniline derivative such as N,N-di-lower-alkylaniline and peroxidase, and finally measuring the optical absorption of the reactant solution of the step III at 570-600 nm. The all steps can be completed within 15 minutes. Therefore, this assay is adoptable for automatic assay of guanase on usual clinically available automatic analyzers.
摘要:
A protein effective in stimulating cell growth activity. The protein has a molecular weight of from 5,000 to about 160,000, is composed predominantly of neutral and acidic amino acids, contains a significant amount of glutamic acid and aspartic acid, and is substantially free of nucleoside phosphotransferase. The protein is useful as wound treatment agent and as promoting agent in the synthesis of DNA. A method of producing the protein and compositions containing the same are also disclosed.
摘要:
A new wound treatment agent which contains as an effective ingredient a fraction containing nucleoside phosphotransferase produced by a nucleoside phosphotransferase producing bacterium belonging to the genus Clostridium, solely or in combination with zinc oxide.
摘要:
Novel synthetic polypeptide derivatives, i.e., novel calcitonin derivatives, having improved basic physiological activities of the corresponding natural calcitonins, i.e., the activity for lowering the blood level of calcium, the activity as an analgesic, as well as the activity for inhibiting the secretion of the gastric juice. Thus these synthetic calcitonins are effective as agents for curing hypercalcemia, analgetic agents, anti-ulcerative agents and the like.
摘要:
This invention relates to a novel 5-fluorouracil derivative represented by the formula ##STR1## wherein R.sup.y is a hydrogen atom or a specific acyl group, Z is a phenyl-lower alkoxy-lower alkyl group, thienyl-lower alkyl group optionally substituted with halogen atom on the thienyl ring, or a group ##STR2## wherein R.sup.1 and R.sup.2 are each a hydrogen atom, a specific acyl group, phenyl-lower alkyl group having a group R.sup.x OCO-- on the phenyl ring, or a group --(A).sub.n B, R.sup.x being a specific organic group, A being a lower alkylene group, n being 0 or 1, and B being a 5- or 6-membered unsaturated heterocyclic group having 1 to 4 hetero-atoms selected from N, O and S and optionally having a benzene ring, naphthalene ring or pyridine ring condensed therewith, with the proviso that R.sup.1 and R.sup.2 are not hydrogen atoms or specific acyl groups at the same time; to a process for preparing the same; and to an anticancer composition comprising the same as an effective ingredient.
摘要:
Amidino compounds represented by the formula ##STR1## and pharmaceutically acceptable acid addition salts thereof are novel compounds and are useful as powerful anti-trypsine, anti-plasmin, anti-kallikrein and anti-thrombin agents. Having strong anti-Cl (Clr, Cls) activities and an anticomplement activity, they are also useful as anticomplement agents. These amidino compounds are prepared by usual esterification of carboxylic acid compounds represented by the formula (II)R.sub.1 --COOH (II)with amidinophenol compound (III) and, if necessary, can be transformed into pharmaceutically acceptable acid addition salts thereof. ##STR2##
