Research Abstract

心停止ドナーを用いた心移植において,proinflammatory cytokineであるinterleukin(IL)-1βおよびtumor necrosis factor(TNF)-α産生抑制の効果を検討した.実験には雑種成犬を用いた.対象を3群(それぞれn=5)に分けた;対照群,FR-1群(IL-1およびTNF-α産生抑制剤であるFR167653をドナーにのみ投与)およびFR-2群(FR167653をドナーとレシピエントに投与).移植前値として,ドナー心の心拍出量(CO)および左心室圧一次微分値(±LVdp/dt)を測定後,FR-1とFR-2群に虚血30分前からFR167653を静脈投与した.腹部大動脈および下大静脈からの急速瀉血により心停止を得た後30分間放置した.ドナー心の冠動脈を4℃のCelsior液でwash-outし,同液でドナー心を4時間保存した後体外循環下に同所性移植した.FR-2群には,大動脈遮断から実験終了までFR167653を静脈投与した.再灌流1時間後に体外循環を離脱し,CVP10mmHgおよびドーパミン5μg/kg/min投与下に再灌流3時間後の循環動態を3群間で比較検討した.病理組織学的検討も行った.結果として,対照群とFR-1群およびFR-1群とFR-2群には循環動態に有意差はなかったが,FR-2群は対照群と比較してCOと-LVdp/dtが有意に良好であった.病理組織学的検討の結果でも,心筋繊維はFR-2群が対照群に比較して良好に保たれていた.ドナーおよびレシピエントにおけるproinflammatory cytokine産生抑制は心停止ドナーからの移植心に有効に作用した.
