Description
牛乳から抽出したラクトフェリン原末(蛋白質として純度97%、タンパク質中のラクトフェリン含有93%)30kgに微結晶セルローズ(商品名;アビセル)57.5kg、デキストリン2.4kg、ステアリン酸マグネシウム0.1kgをミキサーで粉砕し、100メッシュを通過する粉末とした。この混合粉末を打錠機により打錠して直径9mm、重量の錠剤とした。次ぎにコーティング機に錠剤をいれ、ツェイン9%、パルミチン酸モノグリセライド1%、エタノール75%、純水15%よりなる腸溶性コーティング液を噴霧し、対錠剤重量比で10%の腸溶性コーティングを施して製品とした。
48才女性;近眼のために十代からコンタクトレンズを装着していた。しかし、35才のとき眼が痛いので眼科医の診断を受けたところ、ドライアイによる常習性角膜上皮剥離と診断された。それ以来、眼の痛みのため点眼剤が手放せなくなった。2003年3月19日から実施例1で調製した牛乳ラクトフェリンを100mg含有する腸溶製剤を一日2個朝夕に分けて内服したところ、3日目に眼の痛みが消失し、それに伴って点眼薬が不要になった。さらにラクトフェリン腸溶製剤の内服を続け2週間目に眼科医の診断を受けたところ、常習性角膜上皮剥離が治癒したと云われた。また、30年以上も装着できなかったコンタクトレンズを再び使用できるようになった。
ドライアイと診断され、視力が左0.6,右0.5の55才女性が実施例1の錠剤を2カ月、毎日2錠内服した。1週間経過するとドライアイが著しく改善され、視力が左右とも1.0に回復した。3日頃から20年来悩まされてきた頭痛が消失した。頭痛はよく効くクスリがあったが、副作用が出て効力が弱いクスリに切り替えていたがほとんど効果がなかった。しかし、牛乳ラクトフェリンの腸溶錠を一日2錠内服すると頭痛が消失したので、現在、頭痛薬はのんでいない。また、昔からうつ病気味で、過呼吸症候群で二度ほど救急車を呼んで病院に運ばれた経験がある。7月3日に社交ダンスの会合があったが、昔ほど本番前の激しい動悸がしなくなった。ラクトフェリン内服1カ月後で血清中性脂肪が316mg/dlから85mg/dlへと大きく低下した。
45才女性のドライアイが実施例1の錠剤を一日6錠7日間内服して著明に改善された。彼女は18才のときに検眼で近視(左0.5,右0.3)を指摘され、コンタクトレンズをはめるようになった。しかし、30才になってひどいドライアイで、コンタクトレンズがはめるときに痛みが走るようになった。ドライアイは次第に悪化し、40才になると常習性角膜上皮剥離のためコンタクトレンズの装着ができなくなった。眼球が乾燥して痛みがあるため、頻繁に瞬きしなければならず、目薬の携帯が必須となった。しかし、実施例1の錠剤を朝食と夕食直前に3錠ずつ内服したところ、1週間後からドライアイが改善し、目薬の点眼が不要になった。
ドライアイのためにゴルフのスコアが低下していた男性(46才)の視力が実施例1の錠剤を一日3錠内服することにより大きく改善された。彼は三十歳台ではゴルフリンクを70台のスコアで回っていたが、四十才になるとドライアイのために視力が低下し、芝生のアンジュレーションが見えないので落とし所がわからず、パターを打つときには心臓がどきどきして失敗が多かった。2003年5月1日から実施例1の錠剤を一日3錠を毎食前に内服した。内服1週間目に気づいたもつとも大きな変化は、視力が回復してグリーンのアンジュレーションが再び見えるようになったことである。見えるようになってゴルフのスコアが大きく改善され、再び70台後半から80台のスコアが出るようになった。また、パターを打つときも、ビビラなくなったこともラクトフェリン腸溶製剤を内服し始めて起こった大きな変化である。
ドライアイと診断されていた53才の女性の視力が、実施例1の錠剤を一日6錠内服1カ月後に劇的に改善した。2003年4月19日ラクトフェリン錠を内服する直前の視力は、左0.6と右0.8だった。腸溶性ラクトフェリン錠剤(1錠中に牛乳から抽出したラクトフェリン100mg含有)を2錠ずつ10:00,15:00と20:00の一日三回、噛まずに内服したところ、5月24日の視力測定では左右とも視力は1.2に改善していた。この視力改善は、ドライアイが改善されたため頻繁にマバタキをしなくなった結果と思われる。
