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 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. A composition for suppressing and relieving itching comprises 0.1-10 wt.% of the extracts of Zingiber officinale Rosc., Evodia officinalis and Alpinia katsumadai Hayata which are prepared by extracting them with water, C1-C4 lower alcohol or a mixed solvent thereof. The daily dosage of crude drug extracts is 0.001-100 mg/kg, preferably 0.1-30 mg/kg and the composition is a pharmaceutical composition having a formulation selected from ointment, plaster, lotion and liniment, or a cosmetic composition having a formulation selected from skin lotion, skin softener, skin toner, astringent, lotion, milk lotion, moisture lotion, nutrition lotion, massage cream, nutrition cream, moisture cream, hand cream, foundation, essence, nutrition essence, pack, soap, cleansing foam, cleansing lotion, cleansing cream, body lotion and body cleanser.

Abstract:
PURPOSE: Health food or pharmaceutical composition including containing a chestnut skin extract is provided to reduce the pruritus of a user. CONSTITUTION: Health food or pharmaceutical composition contains 0.005-80wt% of chestnut skin extract for reducing or controlling the pruritus of a user. The chestnut skin is selected from the inner skin, the outer skin, or their mixture. The chestnut skin extract is obtained by extracting the chestnut skin using water, low class alcohol having 1-4 carbons, 1,3-butyl glycol, or their mixed solution.
Abstract:
PURPOSE: A composition for relieving skin irritation is provided to suppress expression of inflammatory intermediate factor.
