Abstract「要旨」 直鎖脂肪酸アナログIPPA[ω-(P-iodophenyl)-pentadecanoic acid]を用いて, 基礎的検討および心筋イメージングへの応用を試みた. 白色家兎 (n=6) におけるIPPAの生体内分布の時間推移では肝への集積が高値に保たれ, 30分後において81.0%であるのに対し, 心臓・肺・腎の30分後はおのおの, 30.0%, 10.0%, 15.0%であり, 特に心臓では3分値48.0%より急激な減少を呈し, β酸化の影響によるものと考えられた. 一方, 心筋梗塞モデルを成犬にて作製し, IPPA3mCiを投与すると (n=6) 全例において前下行枝梗塞領域の欠損像を示し, IPPAが心筋症などの心筋代謝疾患だけでなく, 急性期の虚血性心疾患への応用が可能であり, また慢性的な虚血や潜在性の虚血など, 従来のタリウムシンチでは虚血の存在が証明困難であった疾患に対して本剤の有用性が示唆された.

Abstract[Summary] Application for myocardial imaging and fundamental experiments were studied using straight chain fatty acid analog IPPA [ω-(P-iodophenyl)-pentadecanoic acid]. Biodistribution of IPPA in rabbits (n=6) shows the accumulation in liver was maintained 81.0% at 30 minutes, while the accumulations in heart, lungs and kidneys were 30.0%, 10.0% and 15.0% respectively. Especially the accumulation of heart decreased rapidly from 48.0% at 3 minutes to 30.0% at 30 minutes, reflecting the effect of β oxidation. On the other hand, in the acute myocardial infarction mode (n=6) , with occlusion in left anterior descending coronary artery, all 6 cases showed defect images at the corresponding areas after injection of 3 mCi of IPPA. Myocardial imaging with IPPA should be useful not only for myocardial metabolic diseases (cardiomyopathy etc.) but also for ischemic heart disease.
