Abstract
Description
全コレステロール濃度を、分光光度法を用いて、一般的に入手できる分析装置により決定した。
結果は以下の表3〜8に報告する。
(X±S.E.M)(a,b,p<0.01)(A,Bp<0.05)
(SHO=シャム処理済;OVX =卵巣摘出済Wistar ラット)
試験は250 gの平均体重を有するWistarラット(計84の動物が使用される)で実施した。このラットを動物室の条件(温度22℃±2℃、12時間/12時間昼夜サイクル、湿度55%±5%)への順応期間におき、水と飼料を近くに置いた。その後、全ての動物は、高コレステロール血症を得るために、1%のコレステロール(Sigma-Aldrich, 独)と10%のラードを有す栄養価の高い飼料を受けた。
12のラット(6は雌、及び6は雄)を30日で殺した。
12のラット(6は雌、及び6は雄)を60日で殺した。
1. プラセボ群-24のラット(12の雌、および12の雄)
2. 1 gのAKG群-12のラット(6の雌、および6の雄)
3. 0.1 gのAKG群-12のラット(6の雌、および6の雄)
プラセボと実験溶液は、実施例1で記載した。
コレステロールとラードに富む食餌を用いた最初の60日間は、脂質プロファイルを3回チェックして、全コレステロール、LDL及びHDLのフラクション、並びにトリグリセリドの濃度を決定した。前記食餌を開始する前日に計測試験を実施し(0日)、そして引き続き前記食餌の適用の30日及び60日後に行った。試験の61日目に動物を2群に分け:-一方の群はプラセボ溶液を受け、そしてもう一方の群はAKG溶液(投与量0.1と1のAKG)を受けた(表9)。全ての時間において、動物は実験飼料を継続して受けた。プラセボ及びAKG溶液を投与した期間、実験の120日目に脂質プロファイルをチェックした。
試験は、高レベルのコレステロール、194 mg/dl及び190 mg/dlをそれぞれ有するボランティアで行った。チュアブル錠は1.28 gのα-ケトグルタル酸カルシウム(1 gのα-ケトグルタル酸(AKG)と0.28 gのカルシウムに相当する)を個々に含むように調製し、そしてボランティアに経口投与した。実験は計42日間継続した。1日から28日は、患者は1日3回、2錠のAKGを服用した。試験期間において、食事に関する定量的または定性的な制限は導入されなかった。コレステロール、LDL及びHDLのフラクション、及びトリグリセリドの濃度を決定するために、1日から28日間の患者の脂質プロファイルを7日ごとにチェックした。AKG錠の投与は、28日期後の14日間中断した。脂質プロファイルのその後の計測は、実験の42日目に行った。その結果は、以下の表15〜18に示す。
卵巣摘出(OVX)の適用は、一般的に閉経後症候群の中で観察される徴候をシミュレートするモデルアプローチとして見なされ、ラットの血漿中コレステロール濃度を増加へ導いた。AKGの投与量0.01での、60日間の、OVX雌(実験I-1)への適用は、コントロール群の動物において観察されるレベルへと到達するそれらの動物における全コレステロールの濃度において、統計学的に有意な減少をもたらした(p=0.04)。同様の傾向は、AKGを投与量0.1で受けたラットに観察された(実験I-1)。AKGの効果は、延長した卵巣ホルモンの欠如を有す雌でより明白であった(実験I-2)。0.01と0.1のα-ケトグルタル酸は、両投与量ともOVX及びSHO群における分析下での動物中の全コレステロールの濃度の統計学的に有意な減少を引き起こした。更に投与量1のαケトグルタル酸の適用も、卵巣ホルモンの活性の短期間及び長期間不存在に関する実験の両方で、コントロール群に対して、卵巣摘出後の雌における全コレステロール濃度を減少させた。 (実験I-1及びI-2)。
