Research Abstract

フグ体内におけるテトロドトキシン(TTX)の取込・代謝・蓄積・排泄機構、ならびにそれらと性成熟の関連解明に資するため、無毒養殖フグへの毒投与実験を行うとともに、天然フグにおける体内毒分布の季節変動について検討した。その結果、未成熟なトラフグでは、筋肉内投与されたTTXは血液を介してまず肝臓に移行し、その後皮へ移行・蓄積すること、麻痺性貝毒(PSP)保有種メコンフグの場合、PSPを投与すると速やかに皮に移行・蓄積するが、TTXはほとんどが筋肉に残存すること、天然コモンフグの雌においては、性成熟期になると血液中では高分子物質と結合したTTXの割合が増加し、見かけ上、肝臓から卵巣への毒の入れ替わりが起こること、などが示された。
