Description
4 %のキトサン(w/w)を含むゲル
GMPグレードで甲殻類源、脱アセチル化度85%、内因性粘性のキトサン約150 cps(1 %の酢酸溶液中)を精製水に溶解させた。化学量のグルタミン酸をその溶液中に加えると、15から20分後にキトサングルタメートが生産された。その後、無水コハク酸を加えると(グルタミン酸と同量)スクシノキトサングルタメートの形態でゲルが生じた。そのゲルのpHは水酸化ナトリウムで6.8-7.2に調節した。その後、ゲルを160μmのフィルターで濾過し、非所望の粒子を可能な限り除去した。そして、精製水を加えると、濃度4 %の純粋キトサンがゲル中に得られた。得られたゲルは約2500 cpsの粘度を有し、30ゲージの針で容易に注射できた。前記ゲルはpHまたは温度に対し不安定ではなかった。
1 %のキチンミクロスフェア(w/w)を懸濁状態で有する2 %のキトサンを含むゲル
ゲルは実施例1と同様に調製した。ただし、2 %の純粋キトサン濃度(w/w)に調節したことを除く。同時に、キトサンを1 %の酢酸に溶解させ、エタノールを最終溶液の30 %の割合で加えた。Buchiタイプのスプレードライヤーを使用し、粒度5から13μmのキトサンミクロスフェアを得た。これらのミクロスフェアを、酢酸溶液(ポリマーの25から30 %を再アセチル化し、50 %より大きい最終アセチル化を得るために、DDAで計算された化学量の酢酸)に注いだ。結果として生じたキチンミクロスフェアを1 %のミクロスフェア(w/w)を有するように前記ゲルに混ぜた。最終コロイド状懸濁液は約3500 cpsの粘性を有し、そのため27ゲージの針を通して容易に注射することができ、pHまたは温度に対して不安定ではなかった。
1 %のキチン微粉粒子(w/w)を懸濁状態で有する、5%のキトサンを含むゲル
ゲルは実施例1と同様に調製した。ただし、5 %の純粋キトサン濃度(w/w)に調節したことを除く。GMPキトサン供給者から純粋キチンを得た。この粉末の粘度は200-300μmだった。その粉末を微粉化してふるいにかけ、5から32 μmの粒度の粉末を得た。その後、キチン粒子をゲル内で1 %の懸濁状態になるようにゲルに混ぜた。最終懸濁液は約4500 cpsの粘度を有したが、なお27ゲージの針を通して注射可能であった。最終生産物はpHまたは温度に対して不安定ではなかった。
