OHNO, Y., CHIBA, S., UCHIGASAKI, S., UCHIMA, E., NAGAMORI, H., MIZUGAKI, M., OHYAMA, Y., KIMURA, K. and SUZUKI, Y. The Influence of Tetrodotoxin on the Toxic Effects of Aconitine in vivo. Tohoku J. Exp. Med., 1992, 167 (2), 155-158 -Both aconite toxins (aconitine, mesaconitine, and hypaconitine) and a pufferfish toxin (tetrodotoxin, TTX) were detected in the blood of a legal autopsy case. In order to elucidate the in vivo influence of TTX on the toxic effects of aconitine, a mixture of aconitine and TTX was administered to male ICR mice orally or intraperitoneally. The animal experiments revealed that the time of death due to aconitine was significantly delayed in proportion to the dose of TTX compared with the case for aconitine alone, and that the mortality of aconitine was lowered by TTX when the dose ratio of the two toxins was in a particular range. Accordingly, it is thought that the toxic effects of aconitine are attenuated by TTX in vivo.

@YOKOKEN15 @torusengoku この論文の筆頭著者の大野先生が解剖をし、不審に思って血液都心臓を保管し、その後追い詰めた御本人ですね。 https://t.co/j17SKSmOwI
・アコニチン Naチャネルの不活化を抑制し、Na流入を増加。心筋では(致死性)不整脈を引き起こす。半減期は6時間程度 ・テトロドトキシン NaチャネルによるNa流入を阻害し、神経伝達を遮断。半減期は1-2時間 どちらも消化管から速やかに吸収 この事件に関連する論文は以下 https://t.co/QcHUenTFPl

アコニチン(トリカブト毒):脱分極を促進 vs テトロドトキシン(フグ毒):脱分極を抑制 Fight!! Answer 始めは打ち消し合う。 ただし、テトロドトキシンの方が早く分解されるため、最後はアコニチンが勝つ。 https://t.co/RSiVkwnUaO
トリカブト毒を血液中から初めて検出することに成功したのが東北大学と聞いて調べてみた。 Ohno et al. (1992) The Influence of tetrodotoxin on the toxic effects of aconitine in vivo https://t.co/Ol28IpO5IB #何だコレミステリー
There is a reported case of a woman poisoned by her husband with both aconite and tetrodotoxin, delaying her death from either substance. These two deadly poisons have opposite effects and have been shown to attenuate the physiologic response to each other https://t.co/EtnG2coO6p https://t.co/TG3KA05oll
この事件がきっかけと思われる論文にvivioでのテトロドトキシンのアコニチン(トリカブトの毒)への影響の報告例がないと書かれててまじかとなった。 > However, there are no reports on the influence of tetrodotoxin on the toxic effects of aconitine in vivo. https://t.co/frr9GBDnQp
