摘要:
A bacterium of the genus Bacillus is transformed by introducing a vector incorporating DNA encoding an antibody; the resulting transformant is cultivated in a medium to produce and accumulate the antibody in an active form in the culture liquid. According to this method, a recombinant antibody can be easily produced in an active form in large amounts, owing to success in secretory expression using a bacterium of the genus Bacillus.
摘要:
Disclosed is a novel recombinant human lyphotoxin (LT) mutein which combines with an antibody at an inactive site of an LT molecule and liberates the LT molecule easily from the antibody after incorporation of the mutein into tumor cells.The recombinant human LT mutein is prepared by introducing a polydeoxyribonucleic acid containing a nucleotide sequence coding for the particular amino acid sequence into a replicable vector, transforming a microorganism or a cell with the recombinant DNA thus obtained, and cultivating the resulting transformant to express genetic information of the polydeoxyribonucleic acid.The recombinant human LT mutein is useful for tumor-selective carcinostatics, and effective for increasing the actively of LT and reducing the side effects thereof.
摘要:
It is provided an insulin resistance marker, a method of evaluating insulin resistance, a method of screening a substance that improves insulin resistance, and a pharmaceutical composition for improving insulin resistance. An insulin resistance marker including a polypeptide comprising at least any 15 continuous amino acids in the specific amino acid sequence (sequence of a proepithelin protein). An insulin resistance marker including a polynucleotide selected from the group consisting of a polynucleotide comprising at least any 45 continuous bases in the base sequence encoding the above specific amino acid sequence, and a polynucleotide that is complementary to the polynucleotide.
摘要:
A method for producing a sustained-release preparation, which comprises dispersing a physiologically active polypeptide into an organic solvent solution of a biodegradable polymer and removing the organic solvent, wherein the polypeptide is a powder obtained by lyophilizing an aqueous solution of the polypeptide which solution has a water-miscible organic solvent and/or a volatile salt; which improves the ease of handling of the physiologically active polypeptide powder in the process for producing the preparation; which makes it possible to industrially produce the sustained-release preparation in large scale; which provides a sustained-release preparation showing high and stable concentration of the active component in blood in long term, low initial release ratio of the physiologically active polypeptide, and high entrapment ratio of the polypeptide into the sustained-release preparation.
摘要:
The present invention includes a formulation which comprises an antibacterial substance and an antiulcer substance, wherein at least either of them is formulated into a gastrointestinal mucosa-adherent solid preparation. The formulation of the present invention shows long retention time in the gastrointestinal tract because of adhesion to the gastrointestinal tract mucosa, synergetically enhances the pharmaceutical effects of an antibacterial substance, specially antibiotic against Helicobacter pylori (HP) and an antiulcer substance, with very low doses of active ingredients, particularly the anti-HP antibiotic with low prevalence of side effects. The present agent is useful as an anti ulcer agent, showing potent anti-HP activity.
摘要:
This invention provides a pharmaceutical composition comprising a non-peptide osteogenic promoting substance and a biodegradable polymer, which can be safely used as a prophylactic/therapeutic agent for various bone diseases (e.g., bone fractures).

摘要:
This invention provides a pharmaceutical composition comprising a non-peptide osteogenesis-promoting substance and a polyethylene glycol or a derivative thereof, which can be advantageously used as a agent for preventing or treating various bone diseases (e.g., osteoporosis) in view of the high oral absorbability and stability of the active ingredient.
摘要:
A sustained-release microcapsule contains an amorphous water-soluble pharmaceutical agent having a particle size of from 1 nm-10 .mu.m and a polymer. The microcapsule is produced by dispersing, in an aqueous phase, a dispersion of from 0.001-90% (w/w) of an amorphous water-soluble pharmaceutical agent in a solution of a polymer having a wt. avg. molecular weight of 2,000-800,000 in an organic solvent to prepare an s/o/w emulsion and subjecting the emulsion to in-water drying.
