Description
現時点では肝機能障害の予防・改善効果をヘルスクレームとした特定保健用食品、栄養機能食品は存在しないことから、安全性が高く、機能性の確かな肝機能障害予防・改善食品の開発が強く望まれている。
ホスファチジルセリンの機能として、脳機能改善(特許文献2:特開平7−17855号公報)などが知られているが、肝機能障害に有効であるという報告は全く無い。
2.剤型がソフトカプセルであることを特徴とする1記載のANIT誘導肝障害モデルで認められる肝障害を示す疾患に伴う血清GOT、GPT悪化改善剤。
上記の医薬用無毒性担体としては、例えば、グルコース、乳糖、ショ糖、澱粉、マンニトール、デキストリン、脂肪酸グリセリド、ポリエチレングリコール、ヒドロキシエチルデンプン、エチレングリコール、ポリオキシエチレンソルビタン脂肪酸エステル、アミノ酸、アルブミン、水、生理食塩水等が挙げられる。また、必要に応じて、安定化剤、滑剤、湿潤剤、乳化剤、結合剤等の慣用の添加剤を適宜添加することができる。
本発明に関わる肝機能改善剤において、ホスファチジルセリンの投与量は、患者の年齢、体重、症状、疾患の程度、投与スケジュール、製剤形態等により、適宜選択・決定されるが、例えば、一日あたり0.01〜10g/kg体重程度とされ、一日数回に分けて投与してもよい。
機能性食品としては、例えば、ホスファチジルセリンに適当な助剤を添加した後、慣用の手段を用いて、食用に適した形態、例えば、顆粒状、粒状、錠剤、カプセル剤、ソフトカプセル剤、ペースト状等に形成したものを用いることができる。この機能性食品は、そのまま食用に供してもよく、また種々の食品(例えばハム、ソーセージ、かまぼこ、ちくわ、パン、バター、粉乳、菓子など)に添加して使用したり、水、酒類、果汁、牛乳、清涼飲料水等の飲物に添加して使用してもよい。かかる食品の形態における本発明のホスファチジルセリンの摂取量は年齢、体重、症状、疾患の程度、食品の形態等により適宜選択・決定される。例えば、一日あたり0.01〜10g/kg体重程度とされる。
以下に本発明をより詳細に説明するために実施例を挙げるが、本発明はこれらによって何ら限定されるものではない。
マウスにn-naphthylisothiocyanate(ANIT)を投与すると肝障害が引き起こされ、このモデルは肝機能改善剤の評価に汎用されている。
ANIT誘発肝障害に対するホスファチジルセリン(PS)の効果を調べるために以下の実験を行なった。7週齢、雄のddYマウスにANIT(75mg/kg)を経口投与した。ANIT投与の1時間後から、24時間毎にホスファチジルセリン(120mg/kg)をベニバナ油に溶解して経口投与した。ホスファチジルセリンは大豆レシチンを酵素処理して製造したものを用いた。健常対照群、ANITのみを投与した群、及びANITを投与した後ホスファチジルセリンを投与した群の各群について、ANIT投与3日後に肝機能の指標として血清GOT、GPTを測定した。その結果を表に示す。数値は平均値±標準誤差。カッコ内は肝障害対照群(ANIT投与群)に対する有意差を示す(Studentのt-test)。
ホスファチジルセリン45%含有酵素処理大豆レシチン(43.1重量%)、ビタミンEオイル(1.54重量%)、ビタミンB1(0.39重量%)、ビタミンB6(0.78重量%)、ビタミンB12(1.15重量%)、蜜ろう(5.77重量%)となるようにパーム油と混合し、30分間撹拌した。80メッシュで篩過した後、真空撹拌機で脱泡処理を行った。ソフトカプセル充填機により内容量が260mgとなるように充填した。皮膜は通常用いられるゼラチン、グリセリン混合物を用いた。
乾燥後、液漏れ検査、形状選別検査、目視検査を合格した粒について規格試験を行った結果、カプセル長径、カプセル短径、カプセル総重量、カプセル皮膜重量、カプセル内容物重量、皮膜水分含有量、崩壊時間、酸価、過酸化物価、一般生菌数、大腸菌群等の諸規格を満たす製剤であることが確認された。
