摘要:
Organ-preserving liquids comprising, as an active ingredient, an undiluted liquid of a perfluorocarbon compound or an emulsion containing the same at a high concentration and methods for preserving internal organs are disclosed. The internal organ-preserving liquids of the present invention are extremely useful in the clinical situations as organ-preserving liquids in organ transplantation for mammals including humans, especially as preserving liquids for internal organs having likelihood of thermal ischemic disorders. According to the present invention, internal organs (e.g. pancreas, liver) are preserved by immersing the internal organs in an undiluted liquid of a perfluorocarbon or an emulsion thereof at a high concentration, preferably, with oxygen bubbling.
摘要:
An emulsified preparation containing a perfluorocarbon compound comprises 5-50% (w/v) of a perfluorocarbon compound represented by the formula: (wherein R represents a lower perfluoroalkyl group), 1-5% (w/v) of a phospholipid, 0.01-0.1% (w/v) of a fatty acid or an ester or a salt thereof, 0.001-0.01% (w/v) of tocopherol, 0.011-1.1% (w/v) of a pH adjuster, and an adequate amount of an aqueous solvent. This emulsified preparation can be used as an oxygen-carrying infusion fluid or perfusion fluid for preserving organs.
摘要:
An improved yeast promoter wherein HSA productivity is greatly increased by combining SUC2-UAS and GAP-DH promoter, and production method thereof are discussed.
摘要:
A novel alkaline protease promoter and alkaline protease terminator which each effectively function in a host-vector system of molds can be obtained from yellow koji mold. A gene expression unit comprising the promoter and terminator is used to construct an expression vector capable of expressing an useful substance in molds such as Aspergillus oryzae , Aspergillus niger , Aspergillus awamori , Aspergillus sojae , etc.
摘要:
A method of purifying human serum albumin which comprises subjecting human serum albumin-containing solution to heat treatment of about 50-70°C for 1-5 hours in the presence of acetyltryptophan and/or an organic carboxylic acid with 6-12 carbon atoms or a salt thereof.
摘要:
The prostaglandin-containing liposome preparations which are characterized in that positive-charged lipid(s) is (are) incorporated in lipid thin membrane therein are discussed, and according to the present invention, release of prostaglandins from liposomes can be suppressed.
摘要:
The fused yeasts possessing the capabilities of producing foreign proteins of both parent yeasts, comprising a first yeast capable of producing a foreign protein wherein a DNA sequence encoding the foreign protein has been incorporated in the chromosome thereof, and a second yeast capable of producing a foreign protein wherein a DNA sequence encoding the foreign protein has been incorporated in the chromosome thereof, their production methods and methods of producing foreign proteins are disclosed. According to the present invention, noticeable improvement of foreign protein production can be expected.
摘要:
