Abstract:
PURPOSE: A medicinal composition for preventing or treating diabetes and plastic surgery is provided to promote adipocyte differentiation and to enhance volume and elasticity of skin. CONSTITUTION: A medicinal composition for promoting differentiation of adipocytes contains (-)catechin, (-)epicatechin gallate, or (-)gallocatechin as an active ingredient. Adipocyte is human bone marrow mesenchymal stem cell. The (-)catechin, (-)epicatechin gallate, or (-)gallocatechin is isolated from green tea. A medicinal composition for treating and preventing type II diabetes and diabetes complication contains the (-)catechin, (-)epicatechin gallate, or (-)gallocatechin.
Abstract:
PURPOSE: A method and composition for promoting skin regeneration using icariside II is provided to promote proliferation of transient amplifying cells of epidermis base and promote skin regeneration. CONSTITUTION: An icariside II of chemical formula 1 promotes proliferation of skin cells in skin cells. The skin cell is transient amplifying cells(TA cells). A composition for promoting skin regeneration contains the icariside II as an active ingredient. The content of the active ingredient is 0.001-10 weight% based on total weight. The composition regenerates epidermis by promoting proliferation of the TA cells. The composition increases the number of TA cells which express CD71 protein (Cluster of Differentiation 71 Protein) and α6 integrin. The composition increases the expression of CD200(Cluster of Differentiation 200).
Abstract:
PURPOSE: A biomarker of which expression is specifically decreased or suppressed in the sensitive skin is provided to quickly diagnose sensitive skin and used for screening a relieving agent. CONSTITUTION: A biomarker for diagnosing sensitive skin contains gene of which expression is decreased or increased in the sensitive skin compared to healthy skin or a protein encoding the gene. A method for screening a relieving agent of sensitivity comprises: a step of conjugating a candidate agent to a protein encoded by a gene of which expression is increased or decreased in the sensitive skin; and a step of confirming the suppression of protein activity.
