Fig 5. Anaesthetic parameters of adult zebrafish treated with propofol combined with lidocaine or treated with MS222.

a) equilibrium loss, b) loss of touch reaction, c) loss of reaction to a painful stimulus, and d) equilibrium recovery of adult zebrafish after being placed in an anaesthetic bath of 2.5 μg/ml of propofol combined with 50, 100 or 150 μg/ml of lidocaine (P/L; n = 10), and of 100 mg/L of MS222 (100M; n = 8). Each point represents an animal. Data are expressed as median [interquartile range]. * p≤ 0.016 compared with 100 mg/L of MS222.
