遠沈管にリンパ球分離液(Nakarai 社, 日本)を分注し、健常被験者のヘパリン化末梢静脈血20mLを静かに重層して、2300rpm、23℃で20分間遠心分離した。分離後、単核細胞(PBMC)層を分取し、これにRPMI1640液体培地(Gibco BRL社、Grand Island, NY, 米国)を加えてさらに遠心分離を2回行い、PBMCを洗浄した後にRPMI1640培地に再懸濁させた。これを血球計算盤上に分取し、倒立光学顕微鏡にて細胞数を数え、1.0×106 cells/mLとなるように培地で希釈してPBMC懸濁液を得た。なお、PBMCには末梢血中のすべてのTリンパ球が含まれる。
上記<1>のようにして、PBMCを各薬物存在下で培養した後、細胞の増殖率をMTT法により検討した。具体的には、まず培養終了後の細胞懸濁液にMTT溶液を添加し、37℃、5%CO2存在下にてさらに4時間培養した。MTTは増殖細胞中で色素(フォルマザン結晶)に変化するため、この色素の量を比色定量法にて測定することにより、細胞の増殖率を判定することができる。プレートの各ウェルの吸光度を、マルチスペクトロプレートリーダーにて波長550nmにて測定した。このようにして求めた吸光度値から、各濃度の薬物存在下におけるPBMCの増殖率を算出した。セファランチンの各濃度について、メチルプレドニゾロンの濃度に対するPBMCの増殖率をプロットした。結果を図2に示す。
