Description
これまで、インフルエンザウイルスに対する感染防御効果を有する食品成分として、スフィンゴミエリンやラクトフェリン、κ−カゼインにレンネット又はペプシンを作用させた時に生成するペプチドであるκ−カゼイングリコマクロペプチドが知られている。また、発酵乳等に含まれる乳酸菌の1種であるラクトバチルスブルガリクス1073R−1が菌体外に産生する多糖が、腸管に作用してIgAの産生量を増加させるとともに、パイエル板を介してNK活性を上昇させ、インフルエンザウイルスに対する感染防御効果を有することも知られている。
すなわち本発明は、以下の様態を含むものである。
(1)ラクトアドヘリン及び/又はその分解物を有効成分とするインフルエンザウイルスに対する感染防御剤。
(2)前記ラクトアドヘリン及び/又はその分解物が牛乳由来であることを特徴とする(1)に記載のインフルエンザウイルスに対する感染防御剤。
(3)前記ラクトアドヘリン分解物が、ラクトアドヘリンをタンパク質分解酵素を用いて分解したものであることを特徴とする(1)または(2)に記載のインフルエンザウイルスに対する感染防御剤。
(4)前記タンパク質分解酵素が、トリプシン、パンクレアチン、キモトリプシン、ペプシン、パパインからなる群から選択される少なくとも1種である(3)に記載のインフルエンザウイルスに対する感染防御剤。
(5)(1)から(4)のいずれかに記載のインフルエンザウイルスに対する感染防御剤を含むことを特徴とする感染防御用飲食品、感染防御用栄養組成物又は感染防御用飼料。
(6)(1)から(4)のいずれかに記載の感染防御剤を経口摂取することによるインフルエンザウイルスに対する感染防御方法。
さらに、これらを製剤化した後に、これを栄養剤やヨーグルト、飲料、ウエハース等の飲食品、栄養組成物又は飼料に配合することも可能である。
(インフルエンザウイルスに対する感染予防効果の確認)
A型インフルエンザウイルスとしてA/Guinzhouウイルスを、B型インフルエンザウイルスとしてB/Ibarakiウイルスをマウス(Balb/c、雄、6週齢)に経鼻感染させ、同時に実施
例品1をラクトアドヘリンが100μg/mlになるように溶解した溶液と実施例品2のラクトアドヘリン分解物が100μg/mlになるように溶解した溶液を、それぞれ1μl/鼻腔内投与量(投与量:0.1μg)で経鼻投与し、インフルエンザウイルスに対する感染予防効果を、それぞれのインフルエンザウイルスに単独経鼻感染した群(コントロール)と鼻腔内洗浄液中のウイルス価を用いて比較検証した。なお、判定にはMDCK細胞を用いたプラーク法を用いた。その結果を表1に示す。
(経口投与におけるインフルエンザウイルスの感染予防効果の確認)
インフルエンザウイルスPR8(H1N1)を1×103pfuのウイルス量でマウス(Balb/c、雄、6週齢)に感染させた。感染前に、実施例品1と実施例品3を用いて、マウス体重1kgあたり、ラクトアドヘリン又はその分解物を0.1mg経口投与する群と、ラクトアドヘリン又はその分解物を10mg経口投与する群に分け、インフルエンザウイルスに対する感染予防効果をウイルス感染3日後の鼻腔洗浄液中のウイルス価で判定した。また、陽性対象として、感染前に、ラクトフェリンを10mg経口投与する群を設定し、溶媒である水のみを経口投与する群(コントロール)と、MDCK細胞を用いたプラーク法を用いて比較検証した。その結果を表2に示す。
表3に示す配合で原材料を混合後、常法により造粒し、カプセルに充填して、本発明のインフルエンザウイルス感染予防用カプセル剤を製造した。
表4に示す配合で原材料を混合後、常法により1gに成型、打錠して本発明のインフルエンザウイルス感染予防用錠剤を製造した。

脱脂粉乳300gを409gの脱イオン水に溶解した後、実施例品2、1gを溶解し、50℃まで加熱後、ウルトラディスパーサー(ULTRA−TURRAX T−25;IKAジャパン社製)にて、9,500rpmで30分間撹拌混合した。マルチトール100g、酸味料2g、還元水飴20g、香料2g、脱イオン水166gを添加した後、100mlのガラス瓶に充填し、95℃、15秒間殺菌後、密栓し、本発明のインフルエンザウイルス感染予防用飲料10本(100ml入り)を調製した。
実施例品1、2kgを98kgの脱イオン水に溶解し、50℃まで加熱後、TKホモミクサー(MARK II 160型;特殊機化工業社製)にて、3,600rpmで40分間撹拌混合してラクトアドヘリン含量1.56g/100gのラクトアドヘリン溶液を得た。このラクトアドヘリン溶液10kgに大豆粕12kg、脱脂粉乳14kg、大豆油4kg、コーン油2kg、パーム油23.2kg、トウモロコシ澱粉14kg、小麦粉9kg、ふすま2kg、ビタミン混合物5kg、セルロース2.8kg、ミネラル混合物2kgを配合し、120℃、4分間殺菌して、本発明のインフルエンザウイルス感染予防用飼料100kgを製造した。
