Description
これによって、フィブリンシーラントの実効性が増加する。本発明は、さらに低いフィブリノーゲンレベルで有効性を有するフィブリンシーラント製品を提供する。
外傷出血は、高い圧力での動脈損傷から大量の毛細血管出血の範囲に及ぶ異なる形態で現われるので、利用可能な止血剤有効性試験のための普遍的な動物モデルはない。大動物モデル(ブタ)はヒトの状況のための唯一の代表的なモデルである(Pusateri他 (2003年) J. Trauma 55(3), 518−526)。選択した動物モデルにおいて、本発明の粉末製品は、市場のまたは開発段階の外傷適用に使用の可能性のある他の製品と比較される。制御されない重篤な出血を誘導して肝臓に外傷をシミュレートするために、外科用はさみを用いて4×5cmの幅および1.5〜2cmの深さのピースを肝臓(n=2)から切り取ることによって、ブタの肝臓に肝臓スカロップ損傷を行った。この手順の間に切断された静脈または動脈のどれも結束せず、損傷が作製される〜15分前に、標準用量のヘパリンを動物に投与した。
2.ヒュームドシリカ−Aerosil 200(「Aer」)
3.ポリサッカライド−ヘタスターチ(凍結乾燥したVoluven)(「Vol」)
4.多孔質で可溶性の添加物−Parteck SI 150および400(「Part SI 150」および「Part SI 400」)
5.多孔質で膨潤可能な不溶性の添加物−セファデックス200Gスーパーファイン(「Sep 200G」)
表2の(a)は、「青色素がチャンバーの底部(フィルター側)から粉末に侵入することが見られる時間」を示す。(b)は、「青色素の最初の兆候が粉末の上部表面で観察される時間」を示す。(c)は、「全表面が青色である」時間を示す。
a.Aerosil 0.01%については、二重測定の両方とも粉末塊とチャンバーの壁との間に大きな青色の液滴を有する(目視可能な時間=200分、側面から);
b.Parteck 10%については、二重測定の1つにも粉末塊とチャンバーの壁との間に青色の液滴を有する(目視可能な時間=200分、側面から)。
c.50%セファデックスはその初期体積の最大〜5倍膨潤する。
d.10%セファデックスはその初期体積の最大〜2倍膨潤する。
e.以下のものについては「時間=200分」で観察される体積減少があった。
・50%SDアルブミン
・50%Parteck SI400
・50%Parteck SI150
