Description
本発明の好ましい態様によれば、外用剤の形態である上記の促進剤;水溶液の形態である上記の促進剤;噴霧剤又は塗布剤の形態である上記の促進剤が提供される。
例1
肥満・糖尿病マウス(ob/ob)を発毛阻害モデル動物として用いた。ob/obマウスは除毛クリームを用いて除毛した後、1カ月以上を経過しても発毛が全く認められない(図1)。一方、ob/obマウスの由来系統である正常マウス(C57BL/6)では1週間で皮膚にメラニン色素の沈着が見られ、11日後には除毛部全域に渡って発毛が認められ、さらに1カ月後にはほぼ元の状態に生えそろう(図2)。
ob/obマウスの除毛後5日目から1週間、AHL水溶液(10 μM)を40 μL染み込ませたガーゼを貼付した。対照動物としてob/obマウスに溶媒のみを染みこませたガーゼを同様に貼付した。AHL塗布開始から1カ月後にガーゼ貼付部位の皮膚組織を採取し、パラフィン切片のHE染織にて組織学的に解析を行った。結果を図4に示す。
