Description
上記実施例および参照例に従って調製したフィルムを、阻止帯試験にかけ、シュードモナス・エルギノーサ(Pseudomona aeruginosa)に対するそれらの抗菌活性を決定した。比較のために、イナジン(inadine)、インドフレックス(iodoflex)、オキソザイム(oxozyme)およびインドザイム(iodozyme)(4つの従来型ヨード生成性創傷ドレッシング)も試験した。小さい正方形のフィルム6.25cm2を、約1.0×107CFU/mlのストックからのシュードモナス・エルギノーサ(Pseudomonas aeruginosa)と共にインキュベートしたペトリ皿の中央に置き、37℃で一晩インキュベートした後、フィルムの縁からのシュードモナス・エルギノーサ(Pseudomonas aeruginosa)の阻止帯をmmで測定した。
上記実施例および参照例に従って調製されたフィルムを試験して、スタフィロコッカス・アウレウス(Staphylococcus aureus)に対するそれらの抗菌活性を決定した。比較のために、比較のために、イナジン(ID)、インドフレックス(IF)、オキソザイム(OX)およびインドザイム(IX)も試験した。小さい正方形のフィルム6.25cm2を、約1.5×105CFU/mlのスタフィロコッカス・アウレウス(Staphylococcus aureus)と共にインキュベートしたペトリ皿の中央に置き、37℃で一晩インキュベートした後、フィルムの縁からのスタフィロコッカス・アウレウス(Staphylococcus aureus)の阻止帯をmmで測定した。
上記実施例および参照例のフィルム組成物の、ヒトケラチノサイトに対する細胞毒性を下記の通りに評価した。
実施例および参照例のフィルム組成物が細胞増殖および創傷治癒に及ぼす影響を、インビトロ掻き傷応答試験を使用して評価した。ケラチノサイトをコンフルエンスまで増殖させ、ピペットチップで引っかくことによって細い「創傷」を誘導した。創傷縁の細胞は分裂して、創傷部位に移動する。開始から1、2、4および6時間に、標準プロトコールを使用して、パーセント創傷閉鎖を測定した。実施例および参照例の様々なフィルム材料の影響を、これらの材料の試料を引っ掻き「傷」の上に置くことによって決定した。
