Description
0.4w/v%のヒアルロン酸ナトリウム溶液
生理食塩水(Normal Saline、NS)
粘膜隆起力評価
比較例1、比較例2、実施例1及び実施例2によって製造された試料を用いてブタ切除胃の粘膜隆起の高さを肉眼で観察した。粘膜下に試料を注入してからそれぞれ5分、10分、15分、20分、30分経過した後、図2のように粘膜隆起の高さを肉眼で観察し、その結果(それぞれ3回繰り返して測定した平均値)を表1及び図3に示した。
前記試料10mLを、内視鏡用穿刺針(針径:23G)が維持されている10mLの注射筒(ジグ)に充填し、この注射筒のピストンを0.2mm/秒の一定速度で押すことによって、前記試料を内視鏡用穿刺針の先端から排出させながらかかる力の大きさ(Kgf)を測定した。測定(小型卓上試験機:KANA、IM−010)はそれぞれ3回繰り返し、その結果を平均値として下記の表2に示した。
