Abstract: The present invention relates to betaine or a composition comprising the same for accelerating liver regeneration, more particularly, a therapeutic pharmaceutical composition comprising betaine as an active ingredient for promoting the recovery of injured or resected liver to the normal liver. The most effective treatment for chronic liver disease, particularly in the terminal stage, is hepatectomy and liver transplantation. In Living Donor Liver Transplantation (LDLT) that has been increasing since 1990, rapid regeneration of liver tissues is essential for both donor and recipient to inhibit complications and thus for the success of the treatment. Betaine accelerates the recovery and growth of injured liver to the normal liver, so that it can be effectively used for the successful LDLT or therapeutic hepatectomy.

Abstract: Disclosed is a composition for treating or preventing vitiligo or canities comprising Sophora japonica extract as an active ingredient.

Abstract: Provided is a Michael addition product prepared from a multifunctional acryl monomer having multiple hydroxyl groups allowing introduction of acryl functional groups, as a Michael acceptor, and a Michael donor. The Michael addition product is a novel multifunctional compound having an oligomer and a photoinitiator moiety in the molecule. Since it can be cured under a standard UV curing condition without having to add a photoinitiator, it is reduced to air pollution or health problem. Therefore the superior physical properties were obtained by cured coatings without surface tackiness. In addition, its hydroxyl groups allow, through isocyanate bonding or introduction of acryl groups, 3-dimensional crosslinking and molecular and compositional design for improving expandability, friction, and reactivity and hydrophilicity for self-adhesion, hardness of cured film, or the like. Consequently, a very useful, multifunctional or water-dispersible coating composition may be prepared.
