[H2O+COサンプル作製法]
バイアル瓶(マルエム(株)製3mL)に純水を2.5mL入れ、ゴム栓、アルミシールを行い密閉した。次いで、テドラーバッグ(アズワン(株)製1L)に任意のCO濃度のガス(N2バランス)を捕集した。ガスタイトシリンジ(伊藤製作所(株)製MS-GAN500)によりバイアル瓶内の気相部をテドラーバッグ内のガスで約2気圧になるよう置換した。その後、気相部のCOが液相に溶解し、平衡状態に達するまで静置した。
バイアル瓶(マルエム(株)製3mL)にミリスチン酸イソプロピル(和光純薬工業(株)製和光一級)を2.5mL入れ、ゴム栓、アルミシールを行い密閉した。次いで、テドラーバッグ(アズワン(株)製1L)に任意のCO濃度のガス(N2バランス)を捕集した。ガスタイトシリンジ(伊藤製作所(株)製MS-GAN500)によりバイアル瓶内の気相部をテドラーバッグ内のガスで約2気圧になるよう置換した。その後、気相部のCOが液相に溶解し、平衡状態に達するまで静置した。
公知(Takagi,et.al., Med Gas Res. 2012 Sep 3;2(1):23)の方法に従い、潰瘍性大腸炎モデルラット(Wisterラット、雄、6週齢)を作製した。具体的には、6週齢の雄のWisterラットに対し正中線で開腹し、遠位大腸を露出させ、trinitrobenzene sulfonic acid (TNBS)、0.1M-100μl(35% ETOH)を既報に従い、大腸管腔内に注入し、TNBS腸炎を作製した。
そこで、試験開始日から3日目のみにCO含有組成物(溶媒が水であり、1500μMのCOを含有)を投与した以外は、上記(試験1)と同様にして検討を行い、モデルラットの潰瘍面積を測定した。結果を図2に示す。*は水のみを投与した群に対する有意差(P<0.05)を示す。当該結果から、1500μMのCOを含有する組成物を用いた場合、単回投与でも治療効果が奏されることが分かった。
さらに、CO含有組成物を、溶媒がミリスチン酸イソプロピルであり、含有CO濃度が1500μM又は9000μMである点以外は、上記の単回投与試験(試験2)と同様にして検討を行い、モデルラットの潰瘍面積を測定した。結果を図3に示す。*はミリスチン酸イソプロピルのみを投与した群に対する有意差(P<0.05)を示す。当該結果から、高濃度のCOを含有する組成物を用いた場合、溶媒が有機溶媒であっても、また単回投与であっても、治療効果が奏されることが分かった。
[カルボマー+COサンプル作製法]
500mLポリビーカーに純水300gを入れた。スリーワンモーター(新東科学(株)製BL-1200)により400rpmで攪拌させている所に、カルボマー(アクペック:住友精化(株)製501E)を2.79g添加し、240rpmで5時間攪拌し溶解させた。その後、6%水酸化ナトリウム水溶液を15.8g添加し30分攪拌させ、カルボマー水溶液を作製した。200mLビーカーに当該カルボマー水溶液を150mL入れ、25℃の恒温水槽で30分静置した。
SDラットを用いた以外は、上記(試験1)と同様にして、潰瘍性大腸炎モデルラットを作製した。
