(1)カプシノイドを含有することを特徴とする嚥下障害改善剤。
(2)前記嚥下障害改善剤を含有する医薬組成物。
(3)前記嚥下障害改善剤を含有する食品組成物。
(4)カプシノイドの含有量が1nmol/kg〜10 mmol/kgである前記食品組成物。

(6)嚥下障害を有する対象に、カプシノイドを含有する組成物を投与することにより、嚥下障害を改善する方法。
(7)嚥下障害改善用の医薬組成物の製造における、カプシノイドの使用。
本発明においてカプシノイドとは、バニリルアルコールの脂肪酸エステルをいい、その代表的成分としては、トウガラシ類に含有される成分として確認された、カプシエイト、ジヒドロカプシエイト、ノルジヒドロカプシエイトが含まれ、更に、バニリルデカノエイト、バニリルノナノエイト、バニリルオクタノエイト等の、カプシエイトやノルジヒドロカプシエイトと同程度の脂肪酸鎖長を有する、各種直鎖あるいは分岐鎖脂肪酸とバニリルアルコールの脂肪酸エステルをも包含するが、これらには制限されない。カプシエイト(4-hydoxy-3-methoxybenzyl (E)-8-methyl-6-nonenoate。以下、「CST」と略する場合がある)、ジヒドロカプシエイト(4-hydroxy-3-methoxybenzyl 8-methylnonanoate。以下、「DCT」と略する場合がある)、ノルジヒドロカプシエイト(4-hydroxy-3-methoxybenzyl 7-methyl-octanoate。以下、「NDCT」と略する場合がある)は、それぞれ以下の化学式を有する。
また、カプシノイドは、他のトウガラシ属に属する植物中にも存在することが確認されている(園芸学会雑誌58、601-607)。
[製造例]
「CH-19甘」の果実を粉砕し、凍結乾燥の後、3倍容のヘキサンを用いてソックスレー抽出器で油分を抽出した。その後溶媒を蒸発乾固し抽出組成物を得た。この抽出組成物に対して25重量%のトリカプリリン(理研ビタミン(株)製 M-2)を添加、大科工業(株)製流下式薄膜分子蒸留装置(蒸発加熱面積0.024m2、コンデンサ面積0.0088m2)を用い、蒸発加熱温度180℃、真空度12〜14Pa、油脂フィード量1.1g/min.の条件で分子蒸留を行い、カプシノイド含量約9.5%の抽出油を得た。この抽出油に含まれるカプシノイドの成分及び比率は、ノルジヒドロカプシエイト:カプシエイト:ジヒドロカプシエイト=17:60:23であった。また、尚、この抽出油には、約0.005%のカプサイシノイドが含有されると推定された。
以下の実施例においては、上記のようにして得られた抽出油70μLに、使用直前に乳化剤(Tween 80)1mL、99.7%エタノール 1mLを添加し、更に、実施例1においては生理食塩水(大塚)、実施例2においては蒸留水で希釈し、各種濃度のカプシノイド溶液を調製した。同様に、カプサイシン(シグマアルドリッチ社製)30.5mgに、使用直前に乳化剤(Tween 80)1mL、99.7%エタノール1mLを添加し、更に、実施例1においては生理食塩水(大塚)、実施例2においては蒸留水で希釈し、各種濃度のカプサイシン溶液を調製した。
健常成人17人(平均年齢 36±2.6才)に、製造例のカプサイシン溶液(0.49〜1000μM)をネブライザーを用いて一分間毎に15秒吸引させ、1回の吸引で5回以上咳が惹起された濃度(C5)を求めた。
この結果、カプサイシン及びカプシノイドによるC5は、それぞれ2.02μM、86.4μMであり、濃度差は43倍であった。一方、スコビル法による辛味刺激は、カプシノイドはカプサイシンの1000分の1であるため、カプシノイドによると辛味を惹起せずに咳反射を誘発できることが示された。
基礎疾患を有する高齢者男女3名に対し、鼻からカテーテルを口蓋垂の高さまで挿入し、コントロール(水)と各種濃度のカプシノイド溶液(0.1, 0.01, 0.001μM)を1ml滴下し、嚥下反射が起こるまでの潜時(秒、舌骨が挙上して下りてくるまでの時間)を測定した。結果を表1に示す。また、コントロールを100%としたときの潜時の3名の平均値を図1に示す。カプシノイド投与群では、顕著にコントロール時に比して嚥下反射が改善され、図1に示されるように容量依存的な嚥下反射時間の短縮が認められた。
