  • Patent number: 6376461
    Abstract: According to a first embodiment, there is provided a sustained-release preparation comprising a water-insoluble or slightly water-soluble polyvalent metal salt of a water-soluble physiologically active substance which is not an endothelin antagonist, and a biodegradable polymer. The sustained-release preparation of the first embodiment is highly efficient in incorporating the water-soluble physiologically active substance and suppresses the initial burst of the water-soluble physiologically active substance. The sustained-release preparation of the present invention is capable of releasing the water-soluble physiologically active substance while retaining its bioactivity after administration in vivo. Furthermore, the water-soluble physiologically active substance in the sustained-release preparation is kept stable for a long period of time, with little loss of bioactivity.

  • Patent number: 6375974
    Abstract: A process for obtaining an aqueous fumaric acid solution which is useful in stably obtaining a large amount of aqueous fumaric acid solution. A column is packed with solid fumaric acid and then water is passed through the column, thereby giving an aqueous fumaric acid solution. Water is usually passed in the reverse direction. The solid fumaric acid may be in the form of tablets containing 70% by weight or more of fumaric acid. The aqueous fumaric acid solution thus obtained has a pH value of about 1 to 4. A urinal, etc. is treated with a fumaric acid-containing deodorizing agent to thereby efficiently deodorize nitrogen-containing bad-smelling components over a long period of time. A solid deodorizing agent containing fumaric acid, which has an extremely low solubility and a low dissolution rate in water, is placed on a urinal to deodorize the same.

  • Patent number: 6371941
    Abstract: A prefilled syringe has a tubular body which has an open front end and an open rear end. A front assembly is mounted on an outer periphery of a front end portion of the tubular body. A finger grip is mounted on an outer periphery of a rear end portion of the tubular body. A front sealing member is provided in the tubular body so as to be disposed forwardly of injection liquid and a rear sealing member is provided in the tubular body so as to be disposed rearwards of the injection liquid. A plunger rod is provided so as to be movable in the tubular body. A temporary stop member temporarily stops the plunger rod through retention of the temporary stop member by the finger grip such that the rear sealing member is temporarily stopped at a predetermined position of the tubular body. A retention canceling member cancels the retention of the temporary stop member by the finger grip without moving the plunger rod.
