Suture adhesion after surgery is a kind of artificially generated inflammatory adhesion, and it is a complication caused by surgery with a high degree to some extent. Adhesion is not a problem when there is no symptom, but since it can sometimes cause abdominal pain, bowel obstruction (ileus), infertility, etc., various measures have been taken to prevent adhesion.

アルギン酸ナトリウム(キミカアルギンHigh・GシリーズI-1G:1w/v%水溶液、20℃での粘度100~200mPa・s;重量平均分子量約72万(株)キミカ製)、リン酸水素カルシウム・2水和物(和光純薬工業(株)製)およびグルコノ-δ-ラクトン(Spectrum CHenmical Mfg.Corp.USP製)を十分に混合した後、マクロゴール4000の5重量%溶液(溶媒は水)に添加し、温風に晒しながら瑪瑙乳鉢で混練して混合物を得た。その後、混合物を粉砕し、日本薬局方ふるい番号22号(ふるい目710μm)の篩にかけて、粉末状の医薬組成物を得た。各成分の配合量は下表10の通りである。これらの粉末状の医薬組成物は、止血剤として好適な特性を備えるものである。
アルギン酸ナトリウムの代わりにペクチン(SM-666及びビストップD-1382;共に三栄源エフ・エフ・アイ株式会社製)を用いたこと以外は、試験例5と同様の方法で、粉末状の医薬組成物を得た。各成分の配合量は下表11に示す通りである。また、得られた各粉末状の医薬組成物を用いて、試験例5と同様の方法でゲル化速度の測定を行った。結果を下記表11に示す。
雄性ラット(Crlj:WI)(日本チャールス・リバー株式会社より入手)を用いて、腱の癒着防止効果を評価した。具体的には、まず、ラットの足底部の膜性腱鞘を縦切開後、深趾屈筋腱を露出させ半切りすることにより、腱損傷モデルラットを作製した。次いで、半切りした術部及びその周辺に、表12に示す各試験物質50μL投与した。その後、半切りした腱が、ラット自身の運動により断裂するのを避けるために、坐骨神経を切断して、自動運動を制限した状態で、4週間飼育した。4週間後に、各ラットの長趾屈筋のみをつけた状態で足を足首から切り離した。切り離した足の長趾屈筋に60gの荷重を負荷し、負荷前後の第2趾の中足指節関節(MTP)及び近位指節間関節(PIP)の角度を測定した。下記式に従って、負荷前後の屈折角度の差を算出した。また、比較のために、深趾屈筋腱を半切りしなかった正常趾の負荷前後の屈折角度の差についても測定した。
雄性ラット(Crlj:WI)(日本チャールス・リバー株式会社より入手)を用いて、Side-wallと盲腸の癒着防止効果を評価した。具体的には、まず、ラット右腹膜外腹斜筋及び内腹斜筋の1×4cmの筋片を切除し、Side-wallを作製した。次いで、Side-wall内をガーゼで擦過した。また、ラットから盲腸を摘出し、全域をガーゼで擦過し、その後、20分間、空気中に曝露した状態で室温にて静置した。その後、乳酸リンゲル液(株式会社大塚製薬工場社製)で盲腸を洗浄し、表13に示す各試験物質を盲腸の全域に投与した。次いで、Side-wall部分に上記で処理した盲腸を充てて腹腔内に戻して閉腹し、1週間飼育した。1週間後に開腹し、Side-wallと盲腸の癒着の状態を観察した。癒着の状態は、下記に示す判定基準に従って、癒着部位スコアと癒着程度スコアを求め、これらの合計スコアを総癒着スコアとして算出した。
<癒着部位スコア>
スコア:状態
0:癒着なし
1:Side-wall切離部位にのみ癒着が認められる。
2:Side-wall切離部位とSide-wall内の双方に癒着が認められる。
<癒着程度スコア>
スコア:状態
1:軽度癒着;手指で容易に癒着剥離可能な癒着
2:中等度癒着;鈍的な剥離を必要とし、癒着剥離可能な癒着
3:重度癒着;鈍的な剥離を必要とし、組織障害なしでは剥離不可能な癒着
<a法:非持続的な出血に対する止血効果の評価>
雄(Crlj:WI)ラット(日本チャールス・リバー株式会社より入手)を開腹し、左腎を露出して左腎動静脈をクランプし、そこからしみ出る血液を除去して実施例57の粉末状の医薬組成物を約0.3g散布し、生理食塩水で湿らせたガーゼで1分間圧迫した。その後、クランプを解除して5分間に亘って出血の有無を目視により観察した。比較例として、アルギン酸ナトリウムの粉末を散布して同様に測定を行った。
組成物を散布する前にクランプの解除を行う以外は、a法と同様に試験した。
a法において、実施例57の粉末状の医薬組成物を散布し、クランプ解除から5分後の状態を図4のAに、また、ゲル化した実施例57の医薬組成物を取り除いた状態を図4のBに、比較例(アルギン酸ナトリウムの粉末)を散布し、クランプ解除から5分後の状態を図4のCに示す。図4に示されるように、実施例57の粉末状の医薬組成物を散布した場合、クランプ解除から5分後には出血がないことを目視で確認できた。また、ゲル化した組成物を除去しても、出血は確認されなかった。一方、比較例(アルギン酸ナトリウムの粉末を散布)では、クランプ解除から5分後でも、明らかな出血が続き、止血効果は認められなかった。また、b法においても、実施例57の粉末状の医薬組成物は、ほぼ同様の止血効果を示したが、比較例のアルギン酸ナトリウムの粉末では止血効果は認められなかった。
雄性ラット(Crlj:WI)(日本チャールス・リバー株式会社より入手)を用いて、止血効果を評価した。具体的には、ラットの左腎動静脈をクランプした後に、腎の1/3を切除した。次いで、染み出てきた血液を除去し、腎の切断部位に表14に示す試験物質を投与した。その後、スプレーノズル付きシリンジを用いて、生理食塩水約2mLを、腎の切断部位に投与した試験物質の上に撒布し、1分間放置した。その後クランプを解除した。クランプ解除から5分後までの間に、腎の切断部位から出血した血液を医療用ガーゼで吸い取り、吸い取り前後のガーゼの重量の差を出血量として算出した。
