A water-in-oil type oil adjuvant vaccine comprises 20 to 90% by weight of an oil phase A) which is in a liquid state at ordinary temperature; 0.5 to 30% by weight of an emulsifying agent comprising a non-ionic surfactant B) which is a partial ester derived from a polyhydric alcohol carrying at least three hydroxyl groups and a fatty acid and which is in a liquid state at 40°C and a polyoxyethylene (20 to 60 moles) hydroxy fatty acid triglyceride C); and 5 to 75% by weight of an aqueous phase D) containing a biologically acceptable and effective amount of antigens, and optionally E) 0.01 to 10% by weight of an amino acid or a salt thereof and 0.01 to 10% by weight of a non-reducing sugar or a sugar alcohol having at least 5 hydroxyl groups in the molecule. In addition, a water-in-oil-in-water type oil adjuvant vaccine comprises the foregoing water-in-oil type oil adjuvant vaccine as an internal phase and an outer aqueous phase F) comprising 0.2 to 20% by weight of an emulsifying agent which comprises a non-ionic surfactant and which has an overall HLB value of not less than 10. The oil adjuvant vaccines show a high ability to induce an antibody-production over a long period of time and are excellent in requirements for medicines such as stability and safety.
摘要:
A method of culturing animal cells in a medium containing a compound represented by general formula (I), whereby the growth of animal cells can be accelerated at a good reproducibility, wherein R represents COOM or CHO; M represents hydrogen, alkali metal or C1-C3 alkyl; and n represents an integer of 1 to 3.
摘要:
An artificial blood vessel that can be transplanted to blood vessels with a small diameter, can be adjusted to an arbitrary size of a diameter, improves in invasiveness when a graft is taken, and overcomes the problem on the provision of a graft is provided. An artificial blood vessel prepared from a decellularized tubular structure, which is prepared by processing a decellularized, sheet-like blood vessel (decellularized blood vessel sheet) into a roll structure, and a tissue adhesive, wherein a portion which is contacted with blood that flows within the artificial blood vessel consists of the tissue of the tunica intima lined with the tissue of the tunica media whereas a portion of the sheet that overlaps when the sheet is processed into a roll structure (overlap width) consists of the tissue of the tunica media and wherein a tissue adhesive is applied to the overlap width.
摘要:
A spray head 30 for use with a biological tissue adhesive applicator 1 for spraying and mixing solutions accommodated in a pair of syringes 2(2a, 2b) respectively to obtain a biological tissue adhesive to be applied to surgical sites has a first ejection port 42a for ejecting the solution accommodated in one syringe 2a in a predetermined ejecting direction, and a second ejection port 42b for ejecting the solution accommodated in the other syringe 2b in a direction which is the same or substantially the same as said ejecting direction, the second ejection port 42b being disposed forward of the first ejection port 42a. According to the invention, when applying the biological tissue adhesive made by simultaneously spraying and mixing the first and second solutions accommodated in the first and second syringes respectively, no plugging occurs at the ejection ports for ejecting first and second solutions, ensuring intermittent applications of the biological tissue adhesive.
摘要:
Provided are a highly-safe recombinant vaccinia virus that is effective in preventing the onset of symptoms due to infection by novel influenza viruses, and a vaccine for the novel influenza viruses containing the recombinant vaccinia virus. This recombinant vaccinia virus is capable of expressing the hemagglutinin protein genes of the novel influenza virus. This novel influenza vaccine contains the recombinant vaccinia virus.
