摘要:
There are described a novel protein derived from Clostridium perfringens FERM BP-4584 method of obtaining the same and use thereof as an effective ingredient for treating wounds and ulcers. The protein has a molecular weight of 420,000.+-.40,000 by a GPC, isoelectric point of 4.8, and consists of a single subunit having a molecular weight of 130,000.+-.20,000 by a SDS-polyacrylamide gel electrophoresis, and shows cell growth-stimulating activity as well as macrophage chemotactic action. The protein can be extracted and separated by conventional techniques for obtaining a protein from general microorganisms, by taking an inhibition of decomposition into consideration, since the protein is not so stable.

Even when the specimen contains human granulocyte elastase in the form of a mixture of free elastase with an elastase-inhibitor complex or complexes, the present invention enables the total quantity of elastase in that specimen to be precisely detected. The inhibitor is added to free elastase to convert it into an elastase-inhibitor complex, whereby the quantity of elastase can be measured by immunoassay as the total amount including the previously existing elastase-inhibitor complex. It is possible to precisely measure the total amount of elastase in mucus collected from the cervical canal of a pregnant woman, sputum or a rinsed solution of bronchovesicular lavage in which free elastase is mixed with an elastase-inhibitor complex. It is thus possible to predict and prevent threatened premature delivery, premature delivery or premature rupture of membranes by immunoassay of mucus collected from the cervical canal of a pregnant woman, to make a diagnosis of chronic or repetitive airway infections and pulmonary emphysema based on chronic respiratory diseases by immunoassay of sputum and a rinsed solution of bronchovesicular lavage and to make a diagnosis of urinary tract infections by immunoassay of urine.
摘要:
The present invention relates to a new composition designated as AM-1042 or asukamycin. AM-1042 has an antibiotic activity upon Gram-positive bacteria and Eimeria, and its acute toxicity (LD.sub.50 ' ip.) in mice was 48.5 mg./kg. AM-1042 has an excellent therapeutical effect on various infectious diseases caused by a parasite of Gram-positive bacteria and Eimeria. AM-1042 has been confirmed to be distinguishable from known antibiotics such as e.g. amicetin B, azomycin and manumycin. AM-1042 is produced by fermentation of a microorganism belonging to the genus Streptomyces and capable of producing AM-1042. A composition capable of preventing and curing coccidiosis of poultry containing AM-1042 as active ingredient.
摘要:
A novel compound frenolicin B of the formula: ##STR1## is prepared by cultivating a microorganism belonging to genus Streptomyces, e.g. Streptomyces roseofulvus AM-3867, in a culture medium and isolating the compound formed and accumulated in the medium from the cultured product. Said frenolicin B is useful as an antibiotic.

The present invention relates to new compound nanaomycin A and derivatives thereof represented by general formula: ##STR1## in which (a) R is H and R' is OH (nanaomycin A),(b) R is H and R' is NH.sub.2 (nanaomycin C),(c) R is COCH.sub.3 and R' is OH (acetylnanaomycin A), and(d) R is H and R' is OCH.sub.3 (nanaomycin A methyl ester).Nanaomycin A is a new compound of quinone type and its acute toxicity (LD.sub.50, intra-penetrial injection) in mice is 28.2 mg/Kg. Nanaomycin A and derivatives thereof are active on Gram-positive bacteria, trichophyton and mycoplasma and are useful as a medicament for humans and animals. Nanaomycins A and C are produced by culturing a nanaomycin-producing strain belonging to the genus Streptomyces aerobically in a medium to accumulate nanaomycins A and C in the cultured broths. The derivatives acetylnanaomycin A and nanaomycin A methyl ester have similar properties to those of nanaomycin A.

The present invention relates to new compound designated as nanaomycin B represented by general formula: ##STR1## Nanaomycin B is a quinone type and is active on mycoplasma, Gram-positive bacteria and trycophyton. This compound is useful as a medicament for infectious diseases of humans and animals caused by a parasite of trichophyton or mycoplasma etc. The acute toxicity (LD.sub.50, intra-penetrial injection) in mice of this compound is 169 mg/kg. Nanaomycin B is produced by fermentation in which a nanaomycin-producing strain belonging to the genus Streptomyces is cultured in a medium under aerobic conditions and the accumulated nanaomycin B in the cultured broths is recovered therefrom.
