日本SLC株式会社よりC57BL/6Jマウスの雌を4週齢で購入し、入荷当日に視診上健康なマウスを試験に供した。入荷翌日、体重を基に無作為抽出により1群10匹として3群に分け、更に1群を1ケージ当たり3匹、3匹、4匹となるように分けた。オリエンタル酵母株式会社製の基礎飼料MFを、水道水と共に自由に摂取させ、室温23~24℃、湿度30~40%、12時間蛍光灯照明の飼育室において飼育した。
以下に示すとおり、ウイルス感染の有無又は投与薬剤の異なる1)-3)の3群に分けた。
1)群;ウイルス非感染群(CMC経口投与) 10匹
2)群;ウイルス感染群(CMC経口投与) 10匹
3)群;ウイルス感染+ALA+Fe投与群 10匹
ケタラール及びセラクタールによる麻酔下において、インフルエンザウイルスPR8株溶液を両鼻腔より肺へ投与した。ウイルス量は、1匹あたり100PFUとした。本ウイルス感染日をDay-0とした。
各日、AM10:00及びPM17:00に、上記1)群及び2)群には、メチルセルロース溶液(0.5w/v% Methyl Cellulose 400cP Solution,Sterilized:和光純薬)を0.1mL、3)群には5-ALA塩酸塩、クエン酸第一鉄ナトリウムを投与直前にメチルセルロース溶液に溶解調製して、0.1mLをゾンデを用いて胃内に強制投与した。3)群における5-ALA塩酸塩の投与量は、体重1kg当たり15mgを1回量とし、1日あたり体重1kg当たり30mg量とした。また、クエン酸第一鉄ナトリウムの投与量はモル比で5-ALA塩酸塩の0.5倍量となる、体重1kg当たり23.54mgを1回量とし、体重1kg当たり47.08mgを1日量とした。
各ケージを毎日観察し、AM10:00の薬剤投与前に各個体の体重、各ケージあたりの摂食量及び摂水量を測定した。
Day.4及びDay.7に5匹ずつ解剖した。マウスの無麻酔下での断頭により採血し、血液生化学的検査(ケトン体量)を実施した。血中ケトン体量の測定には、「プレシジョンエクシード 3-ヒドロキシ酪酸キット(アボット社)」の測定キットを用いた。
(1)体重の変化
検査に用いた試験群の体重変化を図1に示す。1)ウイルス非感染群、2)ウイルス感染群、3)ウイルス感染、ALA+Fe投与群共に、Day-3までは同様の体重増加が見られた。ところが、2)ウイルス感染群については、Day-4から急激な体重の減少が観察され、観察最終日のDay-7においては、Day-3に比べ約20%の体重減少が見られた。一方、1)ウイルス非感染群においては、Day-5まで体重増加がみられ、その後観察最終日のDay-7まで維持された。3)ウイルス感染、ALA+Fe投与群においては、Day-4まで体重増加が見られ、その後Day-7まで緩やかな減少がみられた。しかしながら、観察最終日のDay-7における体重減少はDay-4に比べ約6%にとどまった。
検査に用いた試験群の摂食量の変化を図2に示す。1)ウイルス非感染群、2)ウイルス感染群、3)ウイルス感染、ALA+Fe投与群共に、Day-2までは同様の摂食量増加が見られた。しかし2)ウイルス感染群については、Day-3でその増加率が他2群に比べ停滞傾向を示し、Day-4から急激な摂食量減少が観察された。観察最終日のDay-7においては、Day-3に比べ約90%の摂食量減少がみられた。一方、1)ウイルス非感染群においては、Day-5まで増加がみられた。3)ウイルス感染、ALA+Fe投与群においては、Day-4まで摂食量増加が見られ、その後Day-7まで緩やかな減少がみられた。しかしながら観察最終日のDay-7における摂食量減少はDay-4に比べ約35%の減少にとどまった。
検査に用いた試験群の摂水量の変化を図3に示す。2)ウイルス感染群については、Day-2までに摂水量の増加は止まり、Day-4には一旦減少した。Day-5では一旦回復したものの、その後急激な減少が見られた。観察最終日のDay-7においては、Day-3に比べ約60%の摂水量減少がみられた。3)ウイルス感染、ALA+Fe投与群においては、Day-6まで摂水量増加が見られ、Day-7で緩やかな減少がみられたが、Day-6に比べ約12%の減少にとどまった。
検査に用いた試験群の血中ケトン体量の変化を図4に示す。血中ケトン体量について、Day-7の値は、Day-4に比べ、1)ウイルス非感染群では変化が無く、3)ウイルス感染、ALA+Fe与群では25%の増加にとどまったが、2)ウイルス感染群の値は、242%の増加と著しい上昇がみられた。
(1)動物及び飼育条件、試験群及び薬剤の投与
動物及び飼育条件、試験群並びに薬剤の投与については実施例1と同様に行った。
ケタラール及びセラクタールによる麻酔下において、鶏卵培養直後の新鮮ウイルスで強い致死率を示すインフルエンザウイルスPR8株溶液を両鼻腔より肺へ投与した(ウイルス実験株の中でもPR8株は最も致死性の高いウイルス株であるが、その中でも培養直後のウイルス株は強い病原性を示す)。ウイルス量は、1匹あたり100PFU又は150PFUとした。本ウイルス感染日をDay-0とした。
各ケージを毎日観察し、全個体に対する生存個体数の割合を生存率とした。また、Day-6以降の、17:00における生存個体の体表面温を測定した。
Day.4及びDay.7に5匹ずつ解剖した。マウスの無麻酔下での断頭により採血し、血液生化学的検査(ATP量)を実施した。血中ATP量の測定には、「XL-ATP kit(アプロサイエンス社)」の測定キットを用いた。
(1)生存率の推移
生存率の推移を図5に示す。ウイルス量150PFUにて感染させると、ALA非投与の2)ウイルス感染群においてはDay-9で、3)ウイルス感染、ALA+Fe投与群においてはDay-10で、全頭死亡した。ウイルス量100PFUにて感染させた場合については、ALA投与の有無でDay-9より生存率に差が発生し、ALA非投与の2)ウイルス感染群はDay-13までに全頭死亡したが、3)ウイルス感染、ALA+Fe投与群は試験期間内に3頭生存した。この結果から、強い致死率を示すインフルエンザウイルスPR8株を用いた場合であっても、生存率が向上することがわかる。
生存しているマウス体表面温の推移を図6に示す。ALA非投与の2)ウイルス感染群においては感染後継続して体温は低下した。死亡個体については24℃台となった翌日に死亡していた。一方、3)ウイルス感染、ALA+Fe投与群においてはDay-9以降、緩やかに回復した。このように、ALA+Feを投与した場合、体表面温度の異常を改善できることがわかる。
検査に用いた試験群の血液中ATP量のDay-4及びDay-7の変化を図7に示す。2)ウイルス感染群のDay-7の血液中ATP量の値は、1)ウイルス非感染群に比べて低い値を示した。一方、3)ウイルス感染、ALA+Fe投与群のDay-7の血液中ATP量の値はDay-7においても低下せず、高い値を示した。また、Day-4に比べても血液中ATP量の値が増加していた。
次に、病原性の低いインフルエンザウイルスPR8株を感染させたインフルエンザ重症化モデルマウスにおける生存率を調べた。すなわち、鶏卵培養直後の新鮮ウイルスで強い致死率を示す実施例2のインフルエンザウイルスPR8株に代えて、培養後-80℃条件下に3~6ヶ月保存経過して強い致死率を示さなくなったインフルエンザウイルスPR8株を用いて生存率を検討した。
