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.
