  • Patent number: 5714169
    Abstract: A topical composition comprising LYCD together with known topically active useful medicinal agents such as anti-wrinkling, antibiotic, anticancer, antifungal, antiinflammatory such as anti-acne, antiviral, wound healing, and hair-growing agents. The LYCD works together with the other active agents to achieve a synergistic result more effective than can be obtained from the topical agents individually, and more effective than could be predicted from the mere addition of the known efficacies of the individual ingredients.
    Type: Grant

  • Patent number: 5397770
    Abstract: A medicinal composition comprising an Epidermal Growth Factor-like protein derived from yeast, and a carrier which is pharmaceutically acceptable and suitable for the type of administration and treatment for which the composition is to be used. The yeast-derived protein Has a molecular weight of about 4770 daltons and a murine Epidermal Growth Factor (mEGF) activity equivalent to at least 100 nanograms of mEGF by Elisa Assay Titration. The medicinal composition may be applied topically for purposes such as the treatment of external body wounds, or in ophthalmic surgery such as in cataract or corneal surgery, by incorporating a carrier therein which is pharmaceutically acceptable for the particular topical use. The composition may be administered orally for treatment of such ailments as peptic ulcers by incorporating therein a carrier which is pharmaceutically acceptable for oral administration in oral dosage form.

  • Patent number: 5219998
    Abstract: A water-soluble yeast protein of about molecular weight 4770 daltons is isolated having murine Epidermal Growth Factor (mEFG) activity per milligram at least equivalent to 1000 nanograms of mEGF by Elisa Assay Titration. The protein is naturally present in yeast and is free of water-insoluble yeast components. The proten is insoluble in trichloroacetic acid, chloroform, absolute methanol, 95% ethanol, acetone, hexanes, petroleum ether, and 50% methanol--25% ether. The protein is soluble in acidic solutions containing 50% methanol, ethanol or acetone. The protein stimulates the growth and respiration of A431 cells in a culture without serum supplements.
