(動物実験による感覚改善効果の確認)
Woolfe, MacDonaldらが開発した熱刺激に対する行動学的研究法であるホットプレート試験にて熱刺激による感覚改善効果を評価した。24週齢のヘアレスマウス(Hos:HR-1)を10匹ずつ3群に分けた。実施例品2の乳由来塩基性タンパク質画分をマウス体重1kgあたりそれぞれ0mg、10mg、20mgになるよう1日1回ゾンデで経口投与して4週間飼育した。投与終了時に54℃のホットプレートにマウスを置き、マウスがホットプレートから足を離す、立ち上がる、ジャンプするなどの逃避行動までの時間を測定した。その際、熱刺激から逃避行動に移るまでの時間(逃避行動陽性反応時間)の最長時間を30秒に設定し、逃避行動陽性反応時間が30秒以上の場合、当該時間は30秒とした。その結果を表4に示す。
(経口摂取による感覚改善効果の確認)
手の感覚の鈍化を感じている健康な高齢者(平均年齢75±3歳)を10名ずつ、5群に分けた。それぞれを、乳由来塩基性タンパク質画分および乳由来塩基性タンパク質画分を摂取しない群(A群)、実施例1の乳由来塩基性タンパク質画分を10mg摂取する群(B群)、20mg摂取する群(C群)、実施例3の乳由来塩基ペプチド画分を10mg摂取する群(D群)、20mg摂取する群(E群)とし、6週間摂取してもらった。摂取前と6週間の摂取終了後に表在知覚計アルゲジオメーター(インタークロス社製)を用い、上腕内側の痛覚を基準として手掌と足底土踏まずの痛覚を使用方法に基づき正常、低下I~IIIの計4段階で測定した。また、6週間の摂取終了後に、それぞれの高齢者に、手の感覚の改善についてアンケート調査を実施した。その結果を表5、6、7、8に示す。
・5種類の太さの違うピンと5つの支点位置で痛覚を評価した。まず、最も細い1pinを上腕内側に転がし、正常な痛覚の度合いを被験者に確認した。
・次に、手掌と足底に1pinにてホルダを持つ支点の位置を順に変えて転がし、最初に感じた痛覚と同程度の痛みを感じる支点の位置を探した。
(評価方法)
アルゲジオメーターは上腕内側で1pin(支点50g)を転がした場合と、手掌での2pin(50g)で同じ痛みを生じる様に設計されており、使用方法に基づき、以下のように評価した。また、痛みの評価に点数をつけ、平均値を算出した。
2pin(50g)で同じ痛みであれば、正常(0点)
1pin(50g)で同じ痛みであれば、低下I(1点)
1pin(60g)で同じ痛みであれば、低下II(2点)
1pin(70g)で同じ痛みであれば、低下III(3点)
