Description
本願は、2008年5月30日出願の米国仮特許出願第61/057,468号(その全体が参照により本明細書に援用される)の優先権の利益を主張する。
試験は全て米国視覚眼科学会(the Association forResearch in Vision and Ophthalmology)の実験動物の管理と使用に関する方針に従って行い、プロトコル(protocol:臨床試験計画表)はコロラド大学動物管理使用委員会(Universityof Colorado Institutional Animal Care and Use Committee)によって認可された。9匹のBrown Norwayラットを動物実験室に収容し、それぞれに前眼部の生体顕微鏡検査を行って登録前に正常な眼表面状態を確保した。これらの動物は全て登録時に正常眼圧であり、同室に収容し、試験全体を通して全く同じ食餌を与えた。
各ラットは麻酔及び処置に耐え、合併症を起こさなかった。処置後に外面的な眼の病変又は白内障の発症は見られず、ラットは追跡期間中、それらのケージの中で正常な行動及び食習慣を維持した。試験の終了時の、瞳孔散大させての検査(dilation)は、剥離又は出血のない正常な網膜の解剖学構造を示した。最初の治療前では、平均IOP(mmHg、SD)は試験眼及び対照眼についてそれぞれ(28.22±1.48)及び(27.78±1.47)であった。処置から2分後の平均IOPの最初の検査は処置眼について(26.67±1.80)及び対照眼について(27.67±1.49)であった。15分の時点でのIOP検査は処置眼について(25.56±1.59)及び対照眼について(27.33±1.05)の平均圧を示した。一週間後、処置眼は平均IOPが(21.56±1.13)であり、対照眼は平均IOPが(27.89±0.99)であった。以下は各被検体についての実際のIOPデータである。IOP測定値は先に処置眼の数値(readings)、次に対照眼の数値を示す。

ウサギの眼の房水流出に対する機械的な振動の効果を調べた。各ウサギに前眼部の生体顕微鏡検査(眼の検査)を行って、登録前に正常の眼表面状態を確保した。各群のウサギを同室に収容し、試験全体を通して全く同じ食餌を与えた。
眼表面にリドカインゲルを使用する表面麻酔を全ての処置前に施した。残りの手技(survivalprocedure)のための全身麻酔にはイソフルランの使用を伴った。各手技は開始から完了まで2分(房水の採取時間を含む)を要した。眼圧はヒト試験及び動物試験において使用されるFDA認可装置であるトノペンを用いて測定され、デジタル読出しが内部圧力を捉えるまで眼の組織を外部から押圧することによって眼圧を測定した。処置前に一滴の抗生物質(ベガモックス(vigamox))をリドカインゲルと共に角膜に入れた。装置を各ウサギの角膜縁区域の上に配置し、その後、重なる箇所のない連続的な接触を用いて360度にわたる機械的な振動力の印加を行った。これは処置される各眼につき約60秒〜90秒の時間を要した。房水の回収には、TBシリンジに通した30ゲージ針を用いて角膜縁(角膜と強膜とが合流する)から入れることにより、総じて50マイクロリットル〜100マイクロリットル吸引した。本方法は、ヒトにおいて診断目的又は試験目的のいずれにも通例的に用いられる。
図4に示すように、処置眼には16.13±1.46〜12.25±2.31の眼圧低下が起こった。これは3.88ポイント(24%)の眼圧低下であった。対照的に、対照眼にはベースラインからのいかなる有意な眼圧低下も起こらなかった。さらに、処置したウサギの房水中のMMP2のレベルは処置前レベルから1週目のレベルへの著しい増加があった。対照眼に比した処置眼の組織では、MMP2の染色は増大し、TIMP2の染色は変わらないままであった。これらの結果は統計的に有意であった。
