Abstract
Description
従って、本発明の課題は、より育毛養毛効果の高い育毛剤組成物を提供することにある。
男性型脱毛症男性3名(37歳男性、63歳男性、62歳男性)各々より採取した毛包を用いて、以下の試験を3回実施した(それぞれ試験(1)、試験(2)、試験(3)と称する)。約10mm2のヒト頭皮組織(後頭部)を採取し、氷冷したリン酸緩衝生理的食塩水に速やかに浸漬した。続いて、消毒用ヨード液で10秒間浸漬消毒した後、70%エタノールで20秒間の浸漬洗浄を2度行い、さらに、リン酸緩衝生理的食塩水で2度浸漬洗浄した。この後、10%牛胎児血清を添加したダルベッコ変法MEM培地(DMEM培地)に組織を浸漬させ、実体顕微鏡下で、マイクロメスを用いて毛包器官を1ケずつ分離した。この毛包器官を、毛包のサイズや形態が均等に分布するよう留意して4群に群分けした(試験1回あたりの各群の毛包器官数〔n〕は8〜10本)。あらかじめ12ウェルプレートの各ウェルに0.5mLの毛包培養培地(William’s Medium E培地に2mM L−Glutamine、ストレプトマイシン(100μg/mL)、ペニシリン(100units/mL)を添加したもの)を入れておき、単離した毛包を各ウェルに1本ずつ静置した。37℃に調温した炭酸ガスインキュベーター(炭酸ガス濃度5%)中で24時間の前培養を行った後、以下に示す4種類の被検物質を各群に1種類ずつ添加して試験を開始し、その後、48時間毎に培地交換および被検物質の添加を繰り返した。第1群には対照として蒸留水を添加した。第2群にはPAPS,4Naを終濃度0.25%となるよう添加した。第3群にはPAPS,4Naを終濃度0.05%となるよう添加した。第4群には陽性対照としてインスリンを含む培地添加物(いずれも終濃度で10μg/mLインスリン、10ng/mLハイドロコルチゾン、10μg/mLトランスフェリン、10ng/mL亜セレン酸ナトリウム)(以降、インスリン類と称する)を添加した。試験開始後、定期的に各毛包の状態を評価し、当該毛包の状態に応じて以下の3つのグループに分類した。評価時点において、毛伸長が継続している毛包を「毛伸長」、毛球部の退行変化を伴って毛伸長が停止した毛包を「毛退行」、試験期間を通じて変化が認められなかった毛包を「無変化」と分類した。
新たに別の男性型脱毛症男性2名(56歳男性、63歳男性)より採取した毛包を用いて、以下の試験を実施した(試験(4)と称する)。実施例1と同様の方法で毛包器官を得た。この毛包器官を、毛包のサイズや形態が均等に分布するよう留意して3群に群分けした。あらかじめ12ウェルプレートの各ウェルに0.5mLの毛包培養培地(William’s Medium E培地に2mM L−Glutamine、アンピシリン(50μg/mL)を添加したもの)を入れておき、単離した毛包を各ウェルに1本ずつ静置した。37℃に調温した炭酸ガスインキュベーター(炭酸ガス濃度5%)中で24時間の前培養を行った後、以下に示す3種類の被検物質を各群に1種類ずつ添加して試験を開始し、その後、48時間毎に培地交換および被検物質の添加を繰り返した。第1群には対照として蒸留水を添加した。第2群には陽性対照としてミノキシジルを終濃度0.05%となるよう添加した。第3群にはPAPS,4Naを終濃度0.05%となるよう添加した。試験開始後、各毛包の状態を実施例1と同様に定期的に判定し、「毛伸長」、「毛退行」、「無変化」の3グループに分類した。
実施例2の各毛包の状態を2日毎に判定し、実施例1と同様に「毛伸長」、「毛退行」、「無変化」の3グループに分類し、この内、「無変化」のグループを本評価から除外した。残る「毛伸長」と「毛退行」の2グループの毛包数の比率を各評価時点で求め、その経時的な変化を追った。
男性型脱毛症男性1名(66歳男性)より採取した毛包を用いて、以下の試験を実施した(試験(5)と称する)。実施例1と同様の方法で毛包組織を得た。この毛包組織を、毛包のサイズや形態が均等に分布するよう留意して3群に群分けした(それぞれn=12)。実施例2と同様の方法で、24時間の前培養を行った後、以下に示す3種類の被検物質を各群に1種類ずつ添加した。第1群には対照として蒸留水を添加した。第2群には陽性対照としてアデノシンを終濃度0.05%となるよう添加した。第3群にはPAPS,4Naを終濃度0.05%となるよう添加した。被検物質添加後、2日毎に培地交換および被検物質の添加を行い、炭酸ガスインキュベーター(炭酸ガス濃度5%)中で12日間培養し、2日毎に写真撮影した。PAPSが器官培養毛包の毛包状態変化に及ぼす影響を詳細に解析するために、実施例1と同様の方法で毛包の状態を経時的に評価した。
