标题 :Methods and compositions for enhancing collagen and proteoglycan synthesis in the skin
发明人：NIMNI MARCEL; HAN BO
权利人:NIMNI MARCEL; HAN BO
摘要:A composition for application to the skin can stimulate the in vivo synthesis of collagen and proteoglycans and improve the appearance of the skin, increasing its elasticity and fullness. In general, a composition according to the present invention comprises: (1) an antioxidant compound in a quantity sufficient to enhance collagen synthesis in the skin; (2) an organic penetrant in which the antioxidant compound is soluble in a sufficient quantity that a concentration of the antioxidant compound sufficient to enhance collagen synthesis can be applied topically and penetrate the skin; (3) a mixture of essential amino acids; (4) a supplemental source of sulfur; and (5) a topical pharmaceutically acceptable carrier. The antioxidant compound can be lipoic acid, a lipoic acid analogue or derivative, a bioflavonoid, a constituent of ginkgo, or an isoflavone. The organic penetrant is preferably benzyl alcohol. Other ingredients, such as esters of tocopherol and ascorbic acid, can be included.

标题:Use of an extract of bauhinia for the preparation of pharmaceutical and cosmetic compositions
发明人：WIRTH CORINNA DR; BUCHHOLZ HERWIG DR
权利人:MERCK PATENT GMBH
摘要:Use of an aqueous or aqueous-alcoholic extract (A) of Bauhinia is claimed to make a composition for cosmetic or pharmaceutical treatment of skin and hair. Use of an aqueous or aqueous-alcoholic extract (A) of Bauhinia is claimed to make a composition for: (a) care, preservation or improvement of the general condition of the skin or hair; (b) prevention and/or inhibition of the aging process for human skin or hair; (c) for promoting healing of wounds; (d) for prevention and/or treatment of skin diseases associated with abnormal keratinization, and (e) for prevention and/or treatment of all malignant or benign growths of the dermis or epidermis. An independent claim is also included for a composition containing (A). ACTIVITY : Dermatological; Vulnerary; Antiseborrheic; Antipsoriatic; Cytostatic; Antiinflammatory; Virucide. MECHANISM OF ACTION : Protein glycosylation inhibitor. In a test, human fibroblasts were cultured in the presence of Vitamin C to stimulate collagen synthesis, then lysed and labeled with tritiated glucose for 15 days, Proteins were removed, extraction and precipitation were carried and the amount of bound glucose measured by liquid scintillation counting. Addition of an aqueous-alcoholic extract of Bauhinia fortificata (0.03 mg/ml), reduced protein glycosylation to 55% of that in a control.
