  • Patent number: 5807951
    Abstract: The present invention provides silicate polymers which regulate the function of a living body by restoring and normalizing the lowered cell functions due to diseases. The silicate polymers are preferably water soluble. The molecular weight of the polymers is in the range of 4,800 to 2,000,000, preferably 20,000 to 1,000,000, and they have a degree of polymerization in the range of 75 to 33,000, preferably 490 to 16,500. The monomer unit is --(SiO.sub.2)--. The polymers may be produced by dissolving a water-soluble silicate or a silicic acid containing material such as water glass in water to obtain an aqueous solution. The solution may be admixed with an acid to adjust the pH to 2-10, preferably 4-9.5. A saccharide or sugar alcohol or pharmaceutically acceptable salt may also be admixed with the solution. The aqueous solution is preferably dried to obtain a powder by heating at 150.degree. C. to 250.degree. C. or by lyophilization.

  • Patent number: 5560935
    Abstract: The present invention provides a physiologically active substance which inhibits plasma kallikrein production, improves peripheral blood flow, and exhibits analgesic, antiinflammatory and antiallergic action. The physiologically active substance of the present invention is prepared by activating various animals or animal tissues by means of inoculation with virus or tumor cells which act as a stressor, and then extracting the effective factor from the activated tissues. The substance exhibits a pharmacological action of inhibiting activity for production of plasma kallikrein and recovering and normalizing abnormal functions which are associated with the diseased state. The physiologically active substance and pharmaceutical compositions of the present invention exhibit excellent regulating activity for biofunctions. They provide recovery and normalization of abnormal functions in living organisms in various diseased states.
