Abstract
【解決手段】人工皮膚モデルを収容した培養装置と、乾燥剤を充填した閉塞性チャンバーで構成される乾燥装置とを用いることにより、ドライスキン状態を惹起、再現できることを見出し、本発明を完成するに至った。
【選択図】図1
Description
本発明に係わる膚乾燥刺激評価装置は、人工皮膚モデルを収容した培養装置と乾燥装置とを用いるものである。本発明に係わる皮膚乾燥刺激評価装置は、乾燥刺激後の人工皮膚モデルの種々パラメータを測定することで皮膚の乾燥刺激を評価できる。
1.試験の概要
2.実験方法
3.結果
乾燥刺激後24時間以内にIL−1α放出量の有意な増加が認められたが、24時間経過後からは、乾燥刺激継続の有無による著しい変化は認められなかった。このことから、乾燥刺激により炎症性応答が惹起されていることが示唆された。これは、乾燥ヒト皮膚においてIL−1RA/IL−1α比が上昇することが知られており、乾燥皮膚内部において微弱炎症の発症が知られていることに一致する。また、乾燥刺激により、セラミド含有量が減少する傾向が認められた。なお、ミトコンドリア活性の低下は認められていないことから、本乾燥刺激がEPISKINに致死性の細胞傷害を与えているものではないことが確認された。以上の結果から、乾燥刺激は、微弱炎症を誘導し、その応答が脂質代謝さらには組織の分化に対し影響を及ぼしていることが示唆された。すなわち、本発明の皮膚乾燥刺激評価装置により乾燥刺激を評価できることが確認できた。
