  • Patent number: 9060958
    Abstract: The present invention provides a highly safe tyrosinase inhibitor having excellent tyrosinase-inhibiting action, and a method for producing the tyrosinase inhibitor. The method for producing a tyrosinase inhibitor comprises the steps of contacting a live earthworm with hydroxycarboxylic acid powder, diluting the resulting mixture with water to adjust the pH to 2 to 5, and then leaving the resulting dilution to stand for 3 to 180 minutes, or contacting a live earthworm with an aqueous solution of hydroxycarboxylic acid having a pH of 2 to 5 and then leaving the resulting mixture to stand for 3 to 180 minutes; followed by washing the live earthworm with water, grinding the washed earthworm, and then freeze-drying the obtained ground product.

  • Patent number: 8394417
    Abstract: Provided is a simple and easy method of producing an innoxious dry earthworm powder, while suppressing inactivation of the enzymes contained in earthworms. In the method, a homogenate obtained by grinding living earthworms is freeze-dried and the dried product is heat-treated at a temperature of 110° C. or higher but lower than 130° C. Preferably, the method according to the present invention comprises further a process for preparation of the living earthworms, which precedes the grinding step, comprising the steps of: standing the living earthworms under light for 10 to 50 hours; removing the dirt formed on the skin thereof, bringing the earthworms into contact with an organic acid for 30 seconds or less; diluting the acid with addition of water to adjust the pH of the aqueous acidic solution to a pH in the range of 2 to 5; standing the earthworm mixture under the pH condition for 3 to 180 minutes; and then washing the earthworms with water.

  • Patent number: 8137701
    Abstract: Provided is a method of producing a dry earthworm powder without deterioration in useful pharmacological action, by removing dirt on the skin of earthworms while allowing the earthworms to excrete the digest remaining in the digestive tracts efficiently without weakening the earthworms, which comprises the steps of: standing living earthworms under light for 10 to 50 hours, removing the dirt formed on the skin thereof, adding an organic acid to the living earthworms, diluting the acid rapidly with addition of water, adjusting the pH of the aqueous acidic solution to 2 to 5, standing the earthworm mixture for 3 to 180 minutes under the pH condition, washing the earthworms with water, grinding the earthworms into a homogenate, freezing the homogenate at ?18° C. to ?35° C., keeping the frozen homogenate for 20 to 240 hours, and freeze-drying and degassing the frozen homogenate under vacuum simultaneously.

  • Patent number: 3988583
    Abstract: A process of producing an electrostatic photographic image by means of X-rays, comprising applying a voltage across two electrodes disposed in opposed parallel relationship, one of the electrodes having a layer of an insulating material on the side thereof facing the other electrode, the space between the insulating layer and the other electrode being filled with an electron or ion emitting liquid. The electrons or ions are generated in the liquid by subjecting the latter to imagewise exposure with X-rays and the electrons or ions are absorbed on the surface of the insulating layer to form an electrostatic latent image. The latent image is then developed with ionized toner to render the same visible.
