  • Medicine, drink, food and feed having an action of strengthening bone
    Publication number: 20020183261
    Abstract: The present invention is to provide a novel medicine, drink, food or feed having an action of strengthening bone. More specifically, the present invention is to provide a medicine, drink, food or feed combined with collagen, fraction containing collagen or degradation product thereof. Fraction containing collagen was prepared by mincing skin corium layer into pieces, defatting it and lyophylization or by pulverizing bone, decalcifying it and lyophylization. Oral administration of these can stimulate proliferation of osteoblast, inhibit bone resorption and strengthen bone. They can be useful for improvement of osteoporosis, bone fracture, bone pain, etc.

  • Basic protein composition, basic peptide composition and application thereof
    Patent number: 5976597
    Abstract: The present invention provides a basic protein and a basic peptide composition which can be administered orally and has the ability to stimulate osteoblast proliferation, strengthen bone and inhibit bone resorption. Said basic protein has the following properties: (1) a molecular weight distribution of is 2,000-24,000; (2) an isoelectric point distribution of is 7.5-11; and (3) it is comprised of more than 10% of basic amino acids. Said composition can be obtained by the following steps: After milk, or raw material derived from milk, is loaded onto a cation exchange resin column, a fraction is obtained by eluting with an eluent of 0.1-1.0M salt concentration, precipitate removed by (i) heating to over 75.degree. C., (ii) by adding alcohol so that the final concentration thereof is 10-50% or (iii) by adding salts so that the final concentration thereof will be more than 0.2M; and the supernatant thereof containing the basic protein fraction recovered.
