    摘要: The invention aims at providing a process for preparing a necrotoxin, an improved toxoid of a necrotoxin produced by a bordetella, and a toxoid mixture comprising the improved toxoid and a toxoid of a necrotoxin produced by a pasteurella. The invention provides a method of partially purifying a necrotoxin by bringing a necrotoxin-containing solution into contact with either a chromatographic carrier gel sulfated by direct sulfation or a chromatographic carrier gel covalently bonded to a sulfated molecule to thereby make the necrotoxin adsorbed on the gel, followed by the elution thereof from the gel. Also provided are a toxoid derived from the necrotoxin produced by a bordetella and partially purified by the above purification method and a toxoid mixture which comprises the above toxoid and a toxoid derived from a necrotoxin produced by a toxigenic pasteurella and is safe for swine and efficacious in preventing atrophic rhinitis.

    摘要: The present invention provides a W/O/W type oil adjuvant vaccine containing an outer aqueous phase containing 0.5 wt% - 20 wt% of a polyethylene glycol derivative having a molecular weight of 400 - 20,000, and an inner aqueous phase containing a biologically acceptable and effective amount of an antigen. The constitution of the present invention that a polyethylene glycol derivative having a specific molecular weight is contained in the outer aqueous phase enables preparation of a W/O/W type oil adjuvant vaccine showing a high adjuvant effect, reduced side effects such as topical response, superior preparation stability and superior workability to allow a person to give an injection easily due to the lowered viscosity.

    摘要: An applicator for spraying tissue adhesive onto an affected portion comprises: a sterilized gas supply chamber; a sterilized gas supply pipe connected to the sterilized gas supply chamber; two sterilized gas injection nozzles for injecting the sterilized gas supplied to the sterilized gas supply chamber in the substantially same direction; two barrel connecting ports, to which forward end nozzles of the barrels are connected; and a spray head having two liquid pipes whose base end portions are connected to the barrel connecting ports and which pass through the sterilized gas supply chamber and project at the forward end portions thereof from the injection nozzles. In this applicator, coating solutions supplied from syringes of the two barrel connecting ports are injected from the forward end portions of the liquid pipes, the sterilized gases are injected from the two gas nozzles in the substantially same direction, and the two types of liquid injected from the liquid pipes are atomized and applied onto the affected portion in a mixed state.

    摘要: A method for activating prothrombin to thrombin which comprises treating an aqueous solution containing prothrombin with polyethylene glycol in the presence or absence of the calcium salt. The method of the invention enables conversion of prothrombin to thrombin in the absence of thromboplastin and allows for preparation of thrombin on industrially large scale from easily available starting materials.
