Description
現代の医療において、創傷治癒処置は、ドレッシング材の使用、基礎疾患(base illnesses)の防御、非生活組織の切除、ホメオスタシス、適切な組織内還流の復旧、創傷部の圧迫制限(pressure limitation)及び感染防御に基づく1。
基礎的な創傷復旧概念
炎症性細胞において増殖因子のプロセスにより引き起こされる直線的な概念を遥かに超えて、修復は、可溶性メディエーター、細胞外マトリックス及び柔組織細胞間の相互作用を表す7。細胞外マトリックス分子は、インテグリン受容体を通じて遺伝子発現シグナルを発し、該マトリックスと組織細胞との相互作用は、形態及び細胞機能を変化させ得る7,8。
局所性及び全身性の両方の多くの因子が、創傷治癒プロセスに影響を及ぼし、肥厚性瘢痕、ケロイド、又は慢性潰瘍、例えば脚部潰瘍、床ずれ、並びに穿孔足底創傷等の、望まれない予後を生じ得る。
コラーゲンは、3本のポリペプチド鎖で構成され、それらの一次配列の部分に平行に三重螺旋を形成する、細胞外マトリックスの糖タンパク質である。
金属セリウムは、強力な殺菌作用を有しながら、哺乳類細胞への毒性が低い26。Burkes及びMcCleskey27は、セリウム塩がインビトロで細菌及び真菌に有毒であることを示した。試験された39種類の細菌において、硝酸セリウムは0.0004Mのオーダーの濃度で増殖を阻害した27。セリウムの静菌作用の生化学的レベルでの基序は未だ不明であるが、多くの可能性を秘めている。細菌の細胞壁に負の電荷が生じることが報告されており、微生物の移動及び凝集が引き起こされる28。また、ランタノイドは、核酸と反応して不溶性の複合体を形成する28。
本発明は、細胞増殖マトリックス、特に非凍結乾燥又は凍結乾燥(ドレッシング材)組成物であって、セリウム塩と結び付いたウシコラーゲン、及び任意でアルギニンを含み、止血性、創傷修復能力、殺菌性、免疫調節能力を有し、過剰の滲出液の吸収が可能で、病変部の浸軟を防止するものの生産に関する。その治療作用は、感染及び創傷の定着の処置、それによる項範囲の殺菌作用に関する。
本発明は、皮膚の病変を処置するための医薬組成物であり、コラーゲンマトリックス上のセリウム塩及び皮膚科的に許容される担体を含むことを特徴とする前記医薬組成物に関する。
a)時期中間組成物を得て;そして
b)工程a)で得た中間組成物を凍結乾燥して、皮膚の病変を処置するためのドレッシング材を形成する
工程を含む、前記プロセスに関する。
本発明の医薬組成物及びドレッシング材は、通常は慢性潰瘍における、構造支持材として作用し、細胞移行を促進し、その他にコラゲナーゼに富む環境において新生コラーゲンを保護する、コラーゲンの生物学的効果と、重度の熱傷及び慢性潰瘍に苦しむ患者において記述されるセリウム塩の殺菌効果及び免疫調節効果との組合せにより、組織修復を促進する。
本発明の製品の静菌性評価は、’Manual de Saneantes do Instituto Nacional de Controle de Qualidade em Saude − Item 8 − B: Metodos para Avaliagao da Atividade Inibitoria de Preparacoes Liquida, Cremosa e Solida − Metodo da Placa de Agar’ − January 1992に従い、以下の微生物:スタフィロコッカス・アウレウス(Staphylococcus aureus)ATCC 6538及びサルモネラ・コレラエスイス(Salmonella choleraesuis)ATCC 10708において実施された。試験の結果、試料周辺に清浄阻害領域(clear inhibition zone)が形成されたことにより、静菌作用が実証された。
