HRMEC(ヒト網膜毛細血管内皮細胞)を6wellプレートにそれぞれ3×105個/mLで播種し、0.5%ジメチルスルホキシド(DMSO)で希釈したアカショウガエキス(赤ショウガエキス-P、オリザ油化株式会社製、図中では「O-2」と表記、以下同じ)0.001%を添加して37℃で30分培養した。7.5%アクリルアミドゲルを用いたSDS-PAGEにより細胞由来タンパク液25μg/laneを分離し、Tw-PBSで調整した1%スキムミルクにてブロッキングした後、1000倍希釈抗P-eNOS抗体(Ser1177、Cell Signaling Technology,Inc.#9715)、5000倍希釈抗eNOS抗体(total、Cell Signaling Technology,Inc.#32037)を加え、室温で1時間インキュベートした後、5000倍希釈ヤギ抗ウサギIgG-HRP(Sigma,#A0545)で室温で1時間インキュベートした。その後、ECL primeで発光させGel dog(Bio-Rad Laboratories,Inc.)でシグナルを検出した。P-eNOS/e-NOSを求め、赤ショウガエキスを加えないときを1として比較した。
経口(舌下)投与による眼血流への影響を評価するため、健常ラットを用いて眼の視神経乳頭周囲の血流量の変化を測定した。
健常ラット(Brown Norway、雄、8-12週齢、SLC社製、体重約200g、以下同じ)におけるベースラインとなる眼血流量をレーザースペックルフローグラフィー(LSFG-NAVI、ソフトケア有限会社製)及び付属の解析アプリケーション(LSFG analyzer)を用いて測定した。当該測定法によると、散瞳剤や造影剤を使わずに非侵襲、又は低侵襲にて眼血流量をリアルタイムに測定、解析することが可能である。
(3-1.眼血流低下型モデルの検討)
健常ラット(Brown Norway、雄、8-12週齢、SLC社製)に麻酔を施し、10分後にエンドセリン-1(図中では「ET1」と表記、以下同じ)を、投与無し(コントロール群)、1.25pmol、2.5pmol、又は5.0pmolにて硝子体内注射し、20分後に、レーザースペックルフローグラフィーにより眼血流量(AveALL(A):全領域の血流量)を測定した。それぞれの測定結果における後眼部血流マップを図2、及び、解析後のグラフを図3に示す。Turkey-Kramer検定により統計処理を行った。
(被験試料の内服群)
健常ラット(Brown Norway、雄、8-12週齢、SLC社製)に、アカショウガエキス粉末を50mgにて舌下投与し、その10分後に麻酔を施し、その10分後に、エンドセリン-1を2.5pmolで硝子体内投与した。エンドセリン-1投与から10分後と20分後にレーザースペックルフローグラフィーにより眼血流量(AveALL(A):全領域の血流量、AveALL(V):血管領域の血流量、AveALL(T):組織領域の血流量)、脈拍、平均血圧、及び、眼圧を測定した。
アカショウガエキス粉末を投与しない点を除き、上記内服群と同様である。すなわち、健常ラット(Brown Norway、雄、8-12週齢、SLC社製)に麻酔を施し、その10分後に、エンドセリン-1を2.5pmolで硝子体内投与した。エンドセリン-1投与から10分後と20分後にレーザースペックルフローグラフィーにより眼血流量(AveALL(A):全領域の血流量、AveALL(V):血管領域血流量、AveALL(T):組織領域の血流量)、脈拍、平均血圧、及び、眼圧を測定した。
また、エンドセリン-1投与から20分後における後眼部血流マップを図8、及び、解析後のグラフを図9~11に示す。student-t検定により統計処理を行った。
生体に寒冷負荷を与えると、皮膚血管からの放熱を抑制するため、血管収縮が起こり、血流が低下する。寒冷負荷後は、時間経過と共に血流が回復する。これらの現象は、寒冷負荷に対して感受性の高いヒトでは、眼血流に対しても同様の現象が起こるとされている。試験例2及び試験例3のように、レーザースペックルフローグラフィーを用いることにより、眼血流量の変化を定量的に評価することが可能となる。寒冷負荷後の血流回復期を短縮できる物質であれば、眼血流の改善及び/又は維持に寄与し、眼部の血管組織の健常性維持、眼部の抗老化、視野狭窄、視野欠損、若しくは暗点等の状態、各種の眼循環障害の治療及び/又は予防に効果的であることが予測される。以下では、クロスオーバー比較試験により、アカショウガエキスの寒冷負荷後の眼血流に対する影響を評価した。
