Repeated exposure groups were anaesthetized to Stage III Plane 1 at seven timepoints every four days (Figure 1), followed by a lethal dose of anaesthetic at day 28. Single exposure groups were left undisturbed throughout the experiment, until day 28 and then treated with a lethal dose of anaesthetic. No significant differences were found between single and repeated doses of respective anaesthetics () Single, and () Repeated1–)gμg(ssuemuscleinResidue140120100180160806040200MS-222AnaestheMetomidatectreatmentAQUI-S
