    Patent number: 7754204
    Abstract: Secondary bile acid production inhibitors and cholesterol-lowering agents containing a yeast as the active ingredient.
    Type: Grant
    Filed: May 22, 2008
    Date of Patent: July 13, 2010
    Assignee: Kabushiki Kaisha Yakult Honsha

  • Adsorbent for endocrine disruptors and foods and drinks containing the same
    Publication number: 20060068047
    Abstract: An adsorbent for endocrine disruptors which contains as the active ingredient viable or dead cells of intestinal microorganisms or constituents thereof. When the adsorbent for endocrine disruptors and foods and drinks containing the same are orally taken either daily or simultaneously with endocrine disruptors typified by bisphenols, alkylphenols and triazines and foods and drinks contaminated therewith, the absorption of these endocrine disruptors into the body can be inhibited and the discharge from the body of the endocrine disruptors, which have been once incorporated into the body, can be promoted.

  • Antiulcer agent and process for preparing the same
    Patent number: 5698534
    Abstract: An antiulcer agent effective on prevention of ulceration and acceleration of healing of ulcers and processes for preparing the same are disclosed. The antiulcer agent comprises rhamnan (a homopolysaccharide), rhamnose or a rhamnose oligomer as an active ingredient. Rhamnan is prepared by separating rhamnan sulfate from rhamnan sulfate-containing algae and desulfurating the rhamnan sulfate. Rhamnan oligomers are prepared by hydrolyzing rhamnan obtained by desulfuration of rhamnan sulfate or by hydrolyzing microbial cells of a Bifidobacterium or polysaccharides separated therefrom.

  • Thrombolytic peptide, production thereof, and thrombolytic agent
    Patent number: 5475089
    Abstract: A thrombolytic peptide composed of 136 amino acids residues, which has little problems of antigenicity and is efficacious in only small doses as compared with staphylokinase (SAK). This peptide is obtained by cleaving amino acids or peptides which do not affect the activity of SAK by using a trypsin protease. In particular, SAK-11, which is obtained by cleaving a peptide composed of ten amino acid residues at the N-terminal of SAK, is superior to SAK in the fibrinolysis, plasminogen activation, and fibrin specificity.
