本発明に係る栄養組成物において脂質源として用いる不飽和脂肪酸について、ω-3系脂肪酸に対するω-6系脂肪酸の含有重量比が、低栄養状態や炎症等の予防、改善効果に及ぼす影響を、以下の実験により検討した。すなわち、6週齢のSD系雄性ラットを4群に分け(各群n=6)、それぞれ表4に示す組成の脂質を含有し、脂質以外は標準精製飼料AIN93G(日本クレア株式会社製)に準じて調製した飼料を等量ずつ2週間摂取させた。その後頸静脈より採血し、血漿中のCRP濃度及びLDLコレステロール濃度を常法により定量した。試験結果を表5に示した。
透析患者において、炎症性サイトカインであるインターロイキン(IL)-6の血中レベルが健常人に比べて高いことが知られている。そこで、本発明で用いる遊離のアミノ酸がIL-6に由来する炎症に及ぼす影響を検討するため、以下の実験を行った。すなわち、6週齢のSD系雄性ラットに浸透圧ポンプ(流速240μL/day)を腰背中部皮下に埋め込み、3群(各群n=5)に分けた。2A群の浸透圧ポンプには、溶媒である1重量%非働化血清含有リン酸緩衝生理食塩水(PBS)を、2B群および2C群の浸透圧ポンプには、IL-6を最終の投与量が400μg/日/kgラットとなるように充填した。また表6に示すように、2A群及び2B群には無タンパク質の標準精製飼料AIN93G(日本クレア株式会社製)に5重量%の大豆タンパク質を配合したものを、2C群にはさらに0.5重量%(0.13g/100kcal)の遊離のアミノ酸(バリン:ロイシン:イソロイシン=1.2:2:1)を配合したものを、飼料としてそれぞれ1週間自由に摂取させた。なお、各群に摂取させる飼料は、コーンスターチにより各群の摂取カロリーが等しくなるように補正した。その後、麻酔下にて腹大静脈下より採血し、血漿中のCRP濃度を常法により定量した。結果を表7に示す。
次いで、本発明に係る栄養組成物において脂質源として用いる不飽和脂肪酸について、ω-3系脂肪酸に対するω-6系脂肪酸の含有重量比、本発明で用いる遊離のアミノ酸及び大豆タンパク質が、腎疾患に伴う炎症の各指標値に及ぼす影響について検討した。本試験においては、6週齢のSD系雄性ラットに偽手術又は腎臓の5/6を摘出する手術を行い、1週間の回復期間の後、表8に示す3群(各群n=7)に分けた。3A群のラット通常飼料としては、標準精製飼料AIN93G(日本クレア株式会社製)よりタンパク質を除いたものに、タンパク質含量が2.5重量%となるように乳タンパク質のみを配合し、コーンスターチでタンパク質含量が20重量%であるAIN93Gとカロリーが等しくなるように補正したものを用いた。また、3B群に摂取させた市販の腎疾患患者用栄養製品Rとしては、タンパク質含量が100kcal当たり3.5gのタイプと1.0gのタイプを2:3で混合し、凍結乾燥させることにより、タンパク質含量が100kcal当たり2.5gとなるように調製したものを用いた。栄養製品Rには、表9に示されるように、大豆タンパク質や遊離の分岐鎖アミノ酸等は配合されておらず、ω-3系脂肪酸に対するω-6系脂肪酸の含有重量比は3.4である。また3C群の飼料としては、表9に示す本発明に係る栄養組成物Aを用いた。なお、3B群と3C群の飼料には、上記CCT(コレステロール:コール酸:チオウラシル=8:2:1)を試験食100kcal当たり1.46g配合した。各群に等量の前記飼料を与えて2週間飼育した後頚静脈より採血し、常法により、炎症性指標であるCRP、IL-6及び末梢血項目である白血球数、好中球数、血清タンパク質等の指標であるアルブミン/グロブリン(A/G)比について、血漿中量の定量を行った。その結果を表10に示した。
