  • Methods of isolating urea, urea compositions and methods for producing the same
    Patent number: 6506305
    Abstract: Urea is readily isolated and recovered from natural products. Urea can be brought into the permeate side by treating a urea-containing fraction extracted from natural products or sewage containing urea, with a nanofiltration (NF) membrane or reverse osmotic (RO) membrane. A milk-derived composition containing urea at a level of more than 0.2% of the total solids can be obtained by treating natural products such as milk or milk materials with an NF membrane or RO membrane to bring a fraction containing urea into the permeate side.
    Type: Grant
    Filed: May 25, 2001
    Date of Patent: January 14, 2003
    Assignee: Snow Brand Milk Products Co., Ltd.

  • Composition for suppressing infection and growth of human immunodeficiency virus
    Patent number: 5725864
    Abstract: The invention relates to compositions and methods for inhibiting infection or suppressing growth of human immunodeficiency virus. The composition comprises, as an effective component, an iron-binding protein (e.g., lactoferrin, transferrin, ovotransferrin), a chemically modified compound of the iron-binding protein, or a hydrolyzed compound of the iron-binding protein. The effective components are safe and can be easily prepared from inexpensive raw materials. The composition can be orally administered, injected or applied to the skin, eye, ear, nose or used as a preparation for vagina affusion, mouth washing or suppositories, and can effectively inhibit infection or suppress growth of human immunodeficiency virus.
