Description
上記の化学式1において、R1、R2、及びR3はそれぞれ独立して水素またはハロゲンであり;
R4はヒドロキシ、アルキル、アルコキシ、ハロゲン、ハロゲンで置換されたアルコキシ、アルカノルオキシまたはニトロであり;
R5は、カルボン酸、アルキル基で置換されたカルボン酸、カルボン酸アミド、スルホン酸、ハロゲンまたはニトロである。
2‐hydroxy‐TTBAのやけどに対する治療効果を検証するために、沸騰したお湯(100℃維持)で3分間予熱した青銅製の櫛(brass comb)を使用して、30秒の間、ラットの背中皮膚の両側に接触によるに熱傷を誘発した。5分後に2‐hydroxy‐TTBA 10mg/5ml/kgを5分にかけて静脈内注射(intravenous injection)した。その後、1日2回(10〜12時間の間隔で)、全部で7日間、同じように投与を継続した。ビークル(Vehicle)投与群では薬物のみが含まれていない同量の生理食塩水のみを同様に投与した。実験グループ(Grouping of Rats for Burn experiments)は、下記の表1のとおりである。
乳酸脱水素酵素(lactate dehydrogenase;LDH)は、ほぼすべての組織に分布している酵素としてピルビン酸(pyruvic acid)と乳酸(lactic acid)との間の可逆的転換に関与して触媒作用をする。組織や細胞が破壊されるときは、血液中に流れ出て、血中のLDHが上昇すると知られている。このため、検査の妨げになる可能性がある溶血した検体を除いた血清から、各グループ間のLDH量を調査した。その結果を図1に示した。
図2は、やけどの損傷後、7日目の背中の皮膚を観察した写真である。実験群のラットの背中の両側に予熱した青銅製の櫛(Brass comb)を使用して、4つの10×20mmの大きさの長方形に皮膚の全層火傷を誘導した。誘導後、2時間目には、背中の皮膚の両側に黒ずんでいる青白い色の4つの凝固帯(zone of coagulation or zone of tissue necrosis)と3つの停滞帯(zone of stasis or zone of tissue injury)が発生した。凝固帯は不可逆的な細胞の損傷部位であって、時間が経っても回復が不能であり、停滞帯は24〜48時間内に特別な処置がなければ細胞の壊死が進行する部位であって、持続的なフィブリン沈着、血管収縮、血栓などで虚血が発生し、細胞を死なせる部位である。
図3は、グループ別に分析組織の部位をヘマトキシリン・エオシン染色し、上皮層の状態を比較した結果である。図3に示すように、正常対照群で観察される健康な毛包を含めて正しく配列された通常の上皮層(矢印で表示された部分)とは違って、やけど対照群では、痂皮を形成し、炎症細胞を除いては、正常な上皮細胞が観察されておらず、ビークル投与群と2‐hydroxy‐TTBA投与群では上皮層の再生が進んでいることが確認できた。このとき、通常の上皮層の厚さ以上に、上皮増殖(Hyperplasia of epidermis)が起きた場合も観察することができた。このような現象を、グループごとに合計28個の組織の部位を分析し、(グループごとに7匹ずつの4カ所の停滞帯の部位)痂皮の形成と上皮層の再生頻度を測定した結果、やけど群で発生した約93%の創傷転換頻度は、ビークル投与群と2‐hydroxy‐TTBA投与群でそれぞれ約18%と4%程度に低下した。また、再生上皮層が観察される場合にも、やけど対照群と比較して、それぞれ約32%と71%に増加した。その結果を下記の表2(Histological appearance:痂皮の形成と上皮層の再生頻度)に示した。
図4は、ヘマトキシリン・エオシン染色を使って停滞帯の皮膚全層組織の状態を10倍率の顕微鏡で観察した写真である。やけど対照群では上皮層、真皮層、皮下組織や筋肉層まで全層にわたって損傷されていることが分かり、痂皮を形成し、その下に炎症細胞が浸潤しており、皮下組織と筋肉の間で多数の炎症細胞が存在していることを観察することができた。ビークル投与群は、かさぶたのような痂皮を形成していないが、相当量の炎症細胞が全皮膚組織や皮下組織にかけて観察され、再生される上皮層の下にまだ多くの炎症細胞が浸潤していた。2‐hydroxy‐TTBA投与群では筋細胞や皮下組織層の部位を除いては、炎症細胞の浸潤がかなり抑えられていることがわり、上皮の再生はもちろん、毛包や皮脂腺、筋肉層においても、保護効果が認められた。
図5は、クレシルバイオレット染色を介して停滞帯組織の生きた細胞を10倍率の顕微鏡で観察した写真である。やけど対照群とビークル投与群では、毛包がほとんど観察されておらず、大量の炎症細胞が皮膚の全層に渡って観察される一方、2‐hydroxy‐TTBA投与群では生きている毛包と上皮層が観察され、相対的に炎症性細胞は少なく観察された。
図6は、Masson’s trichrom染色を通じて停滞帯皮膚組織のコラーゲンと筋線維を観察した顕微鏡写真の結果である。正常対照群では、青色のコラーゲンは、真皮層全体に均一に分布して筋線維が赤色に染色されたが、やけど対照群では、痂皮の下にコラーゲンが不規則に沈着しており、その染色程度も、通常に比べて相対的に弱かった。筋線維もほとんど損傷を受けて染色されなかった。ビークル投与群では、他のグループに比べて相対的にコラーゲンの量が最も多く観察され、これは正常対照群に比べても非常に高い水準だった。また、筋線維は損傷を受けて染色されなかったり、または、相当量の出血と炎症細胞の浸潤を伴っていることが観察された。しかし、2‐hydroxy‐TTBA投与群では正常対照群と同様に上皮層、真皮層、皮下脂肪、筋肉層に区分されて現れ、生きている毛包の周囲にコラーゲンが均等に分布しており筋線維もまた、赤く染色されて現れた。
