  • Patent number: 9155697
    Abstract: Provided is a liquid composition for treating stomatitis, the liquid composition including: an epidermal growth factor; an adhesive polymer; and at least one stabilizer selected from the group consisting of ethylenediaminetetraacetic acid (EDTA) and salts thereof, histidine, lysine and inorganic acid salts thereof, arginin and inorganic acid salts thereof, and dextran. The liquid composition includes a stabilizer selected from EDTA (or salts thereof) and a certain amino acid (or inorganic acid salts thereof) and thus, physicochemical and biological stability of the epidermal growth factor can be substantially increased. Thus, the liquid composition can be stored and distributed for a long period of time. The stabilized composition includes an adhesive polymer, and thus, when ejected in a spray form in the mouth of a user, the liquid composition can be quickly attached to an inflammation site and exhibits effectiveness for a long period of time.

  • Patent number: 8685440
    Abstract: The present invention relates to a nanoliposome comprising a liposome membrane containing esterified lecithin, and one or more physiologically active ingredients included in inner space of the liposome membrane; a method for preparing the same; and a composition for preventing or treating skin diseases, comprising the same. The nanoliposome according to the present invention has long-term stability and uniformity, and so can be used to prepare a composition for skin having excellent moisturizing and penetrating properties, such as cosmetics, medicament for treating skin diseases, or the like. In particular, the present composition for preventing or treating skin diseases comprises epidermal growth factor included in the nanoliposome, thereby showing an excellent effect of stimulating skin-penetration and good pharmaceutical stability.
