摘要:
The present invention is aimed at providing an anticancer agent which can inhibit the metastasis of cancer cells when used alone. In addition, the present invention is also aimed at providing an anticancer agent which can inhibit the metastasis of cancer cells while causing a small side effect and very small toxicity even for an extended time of administration. The cancer metastasis-inhibiting anticancer agent according to the present invention is characterized by containing sialic acid, its salt, a polymer of sialic acid or a salt of the polymer as an effective ingredient.
摘要:
Therapeutic drugs for endotoxin blood symptom and multi-organ failure induced by it is provided, which therapeutic during are composed of sialic acid its salt, polymers of sialic acid or a salt of the polymer as effective components and have high therapeutic effects for shock death and organ failure induced by endotoxin as well as high safety, and are effective for treatment of endotoxin-shock, and organ failure.
摘要:
A rapid and reliable method is proposed for the quantitative determination of the individual free and acetylated polyamines, i.e. spermine, spermidine, putrescine, acetylspermine, N.sup.1 - and N.sup.8 -acetylspermidines and acetylputrescine in the body fluid of a patient suffering cancer or other deseases to facilitate diagnosis and therapeutic treatment. The method comprises subjecting the aqueous fluid to several enzymatic oxidative decomposition reactions of the polyamines in sequence or in combination by use of the 4 enzymes, i.e. polyamine oxidase AT-1, polyamine oxidase PC-3, putrescine oxidase and acetylputrescine oxidase, and determining, preferably photometrically, the amount of hydrogen peroxide formed as a byproduct in each of the reaction steps followed by setting up a set of simultaneous equations to give the respective amounts of the individual polyamines as a function of the amounts of the hydrogen peroxide formed in the reaction steps and solving the simultaneous equations.
摘要:
The invention discloses that the tissues of earthworms contain fibrinolytically or thrombolytically active ingredients which can be extracted and purified by a suitable sequence of extraction and purification procedures into the individual active ingredients including six novel proteases named F-O-HM-45, F-I-1-HM-54, F-I-2-HM-15, F-II-HM-64, F-III-1-HM-27 and F-III-2-HM-89. The chromatographic fractionation of the earthworm extract with an aqueous extractant gives five active fractions, the first four of which contain each one of the first mentioned four proteases and the last of which contains the last mentioned two proteases. The disclosure includes description of the suitable purification methods for the proteases as well as the physico-chemical identification data thereof. Various thrombolytic medicament forms prepared with the novel proteases as the effective ingredient are described together with the results of the clinical tests carried out by the oral administration of the novel proteases.
摘要:
Provided are rice grains where various water-soluble high molecular substances are retained without applying pressure to the rice grains. Grains of mutant rice (wx/ae rice), which is deficient in both amylopectin branching enzyme (BEIIb) and amylose synthetase I (GBSSI), are immersed in an aqueous solution of a water-soluble high molecular substance such as digestion resistant dextrin, arabinogalactan, or polyphenol under ordinary pressure at room temperature and are then dried at 60° C. or less, preferably about 50° C., thereby producing rice grains impregnated with and retaining the high molecular substance.
