Description
(1)PAPSまたはその塩を有効成分として含有する皮膚外用剤を提供するものである。
ヒト表皮角化細胞(HEK)を75cm2フラスコでヒト表皮角化細胞培地(KGM)にて37℃、5%CO2下で培養し、トリプシン処理により細胞を回収した。回収した細胞を3×104cells/cm2の細胞密度になるようにKGMで希釈した後、直径35mmシャーレに播種し、37℃、5%CO2下で培養した。細胞をサブコンフルエントの状態まで培養した後、KGMで希釈した試料溶液を各シャーレに2mLずつ添加し、37℃、5%CO2下で4時間培養した。培養終了後、培地を除き、細胞からRNeasy Mini kit(QIAGEN社製)を使用して総RNAを抽出した。
紫外線照射マウスを用いてセラミド産生促進効果を評価した。5週齢の雄性ヘアレスマウス(Hos:HR−1)(日本SLC産)を自由摂餌(固型飼料CE−2,日本クレア)、自動給水、12時間明暗サイクルの環境下で2週間予備飼育した後、紫外線照射をおこなった。マウス背部にFL20SBL−Bランプ(NEC社製)を用いて1.2mW/cm2の強度で1日3時間、週5回、16週間継続して紫外線を照射することにより、紫外線照射マウスを作製し、実験に供した。
バリア機能障害モデルマウスを用いてPAPSのバリア機能改善効果を評価した。4週齢の雄性ヘアレスマウス(Hos:HR−1)(日本SLC産)を自由摂餌(固型飼料CE−2,日本クレア)、自動給水、12時間明暗サイクルの環境下で4週間予備飼育した後に以下の試験に使用した。
