(1)創傷作成
成熟白色家兎(体重約2kg)に、ペントバルビタールナトリウム(0.4mL/kg)を耳静脈麻酔し、開瞼器で瞼を大きく開き、ベノキシール点眼液30μLを点眼して眼表面麻酔した。その後、n−ヘプタノールで湿潤したメンブランフィルター(直径6mm)をウサギの角膜中央に1分間静置して角膜損傷を発生させ、フィルター除去後、眼を滅菌生理食塩水で十分に洗浄した。
創傷作成後3、4および5時間後に、実施例1および実施例2の角膜疾患治療剤(点眼剤)を100μL点眼した。また、実施例1に対しては2%エタノールおよび2%ポリソルベート80を含有する生理食塩水を、実施例2に対しては5%エタノールおよび2%ポリソルベート80を含有する生理食塩水をそれぞれ対照として用いた。
創傷作成から24時間後に、1%フルオレセイン水溶液(50μL)を点眼して眼を染色し、染色後、余分なフルオレセインを滅菌生理食塩水で洗い流した。次にフォトスリットランプに装着したデジタルカメラにて角膜の写真撮影を行い、創傷の治癒具合を観察した。
各実験において製剤投与後、および24時間後における染色面積を画像処理ソフトウェアを用いて、開瞼器のラベル幅(5mm)を基準として測定し、これを創傷面積とした。その結果より、治癒率を下式に従って算出した。
SA:創傷作成直後の創傷面積
SB:製剤投与後の創傷面積
