Flurothyl toxicity: a remarkable species difference between chick and mouse

  • 25 Accesses

  • 5 Citations


Young chicks survive flurothyl vapor concentrations that are lethal to mice. For a 10-min exposure, the LD50 concentrations (% v/v) of flurothyl are 10.1% in chicks and 0.33% in mice; the convulsant concentrations (CD50) are 0.49% in chicks and 0.32% in mice. The remarkable resistance of young chicks to flurothyl toxicity may be related to their known resistance to hypoxic death.
