Abstract:
A method for inducing itch and a method for screening an itch inhibiting material using glucosylsphingosine are provided to be useful for studying and understanding the itch, thereby being very usefully used for developing a therapeutic agent for the itch and evaluating the effect of a medicine. A method for inducing itch comprises a step of administering at least one compound selected from the group consisting of glucosylsphingosine and a derivative thereof into an animal except human. A method for screening an itch inhibiting material comprises the steps of: (a) administering an itch inhibition candidate material to an animal where the itch is induced by administering at least one compound selected from the group consisting of the glucosylsphingosine and the derivative thereof; and (b) counting a number when the animal scratches. A method for evaluating the itch inhibition effect comprises the steps of: (a) administering an itch inhibition material to an animal where the itch is induced by administering at least one compound selected from the group consisting of the glucosylsphingosine and the derivative thereof; and (b) counting a number when the animal scratches. A composition for inducing itch comprises at least one compound selected from the group consisting of the glucosylsphingosine and the derivative thereof as an effective ingredient.
Abstract:
A method for inhibiting the expression of CCL27/CTACK(Cutaneous T-cell-attracting chemokine) is provided to regulate SPC(sphingosylphosphorylcholine) inducing expression of CCL27/CTACK, so that the method is useful for prevention and treatment of diseases associated with overexpression of CCL27/CTACK including atopic dermatitis, psoriasis and inflammatory skin disease. The expression of CCL27/CTACK is inhibited by administering an effective amount of sphingosylphosphorylcholine regulator capable of inhibiting activity of SPC or competing with the mechanism of SPC inducing overexpression of CCL27/CTACK to a mammal requiring the expression reduction of CCL27/CTACK. A method for screening the SPC regulator comprises the steps of: (1) treating a testing cell such as keratinocyte with 2-10 muM of SPC or its derivatives to induce overexpression of CCL27/CTACK; and (2) treating the overexpression of CCL27/CTACK-induced cell with a candidate material and measuring the expression inhibition of CCL27/CTACK. Further, the mammal has an atopic dermatitis or psoriasis.
Abstract:
A composition comprising minoxidil, tretinoin(all-trans retinoic acid), a solvent and glycerine is provided to promote permeation of the minoxidil without stimulus of the tretinoin, thereby inducing hair growth and alleviating alopecia. An external composition for preventing hair loss and promoting hair growth comprises 0.5-7.5 weight/volume% of minoxidil as a hair growth ingredient, 0.007-0.015 weight/volume% of tretinoin, 72-83 weight/volume% of ethanol, and 15-20 weight/volume% of glycerine.
Abstract:
A composition comprising extracts of crude drugs is provided to suppress and relieve itching caused by inflammatory and atopic dermatitis without side effects such as toxicity and skin irritation.
