Abstract:
A culture medium containing human serum albumin obtained by genetic manipulations (rHSA); a method for culturing animal cells characterized by culturing the cells in the above-mentioned medium; and a process for producing a physiologically active substance characterized by culturing animal cells capable of producing the physiologically active substance in the above-mentioned medium and taking up the produced physiologically active substance from the culture. The use of rHSA with uniform qualities makes it possible to achieve the proliferation of the cells and the productivity of the physiologically active substance each comparable to those achieved by using a serum-containing medium and/or a conventional serum-free medium containing HSA originating in plasma while stabilizing the medium qualities and ensuring the reproducibility of the culture.
Abstract:
Serum-free media characterized by containing insulin and peptone but being substantially free from albumin and transferrin; a method for culturing animal cells characterized by culturing the cells in the above-mentioned media; and a process for producing physiologically active substances characterized by culturing animal cells capable of producing the substances in the above-mentioned media and recovering the substances thus produced from the cultures. These serum-free media allow sufficient proliferation of cells, facilitate the recovery of the physiologically active substances from the cultures, and are scarcely contaminated, thus enabling the provision of the above-mentioned culture method and production process.
Abstract:
A complex comprising GPIb and a lipid having a functional group. As it can bind with vWF and can form aggregates, it is useful as a platelet substitute, medicines for preventing and curing vascular lesion, vascular injury and thrombosis, a diagnostic agent for vWF deficiency, biological-medical reagents, and reagents for screening platelet aggregation inhibitors and antithrombotic agents. Also, as it is apt to specifically concentrate around the lesioned vascular parts, it is useful as diagnostic agents for testing vascular lesion, injured parts and thrombosed parts or remedies therefor.
Abstract:
A more safe immunoglobulin preparation, especially one used for intramuscular injection, that can be obtained by an efficient and well-operable production process without causing viral contamination. The preparation is HCV genome negative, contains HCV genome in a concentration of at most 1 PCR unit/ml in a 0.1-15 w/v % immunoglobulin solution, and has a HCV genome removal rate of 10 or above.
Abstract:
A motor-function disorder preventive or remedy, tissue trouble preventive or remedy, spinal ischemia preventive or remedy, and spinal injury preventive or remedy, each containing a human-origin antithrombin III as the active ingredient. The antithrombin III has the activity of ameliorating mammalian tissue troubles and motor-function disorders, especially those caused by spinal ischemia or spinal injury, for example, paralysis.
Abstract:
A controlled-release AIT (allyl isothiocyanate) preparation comprising AIT and shellac serving as a barrier against AIT release; the above preparation comprising a shellac containing AIT incorporated therein (an AIT-incorporating shellac); the above preparation wherein the AIT-incorporating shellac is in the form of plate, block or granule; the above preparation wherein the AIT-incorporating shellac has been adhered onto or mixed into a base material; the above preparation wherein the base material is one selected from among plastic plate, paper, non-woven fabric and woven fabric; and the above preparation wherein the AIT of the AIT-incorporating shellac is supported on a carrier. The AIT vapor release rate can be varied by appropriately selecting the chemical composition, preparation process and so forth of the AIT-incorporating shellac. Sustained release of AIT vapor for long is also possible. As the AIT-incorporating shellac can be easily worked into various forms, the AIT preparation can be provided in various forms. It is useful in various fields of food, packaging material, construction material and so forth as a functional material which is highly stable and has antimicrobial, antimold, freshness-retaining and insectproof properties.
Abstract:
A pyridothiazineacetic acid compound represented by general formula (I) or a pharmaceutically acceptable salt thereof, a process for producing the same, and a pharmaceutical composition, an aldose reductase inhibitor and a preventive and therapeutic agent for the complications of diabetes, wherein each symbol is as defined in the specification. The compound and pharmaceutically acceptable salts thereof have an aldose reductase inhibitor activity and an excellent stability, and hence they are useful as preventive and therapeutic agents for the complications of diabetes, such as faulty union of injured cornea, cataract, neurosis, retinopathy and nephropathy, in particular, cataract and neurosis. The invention process serves to produce the above compound efficiently.
Abstract:
A benzothiazole compound represented by general formula (I) and a pharmaceutically acceptable salt thereof wherein, R represents halogen; R and R represent each independently hydrogen or halogen; R represents hydrogen, halogen, lower alkyl, alkoxy or alkylmercapto; and R represents hydrogen or lower alkyl.
