  • *, P < 0.05; **, P < 0.01; ***, P < 0.001 significantly different from control.

  • a Mean ± S.D., n = 5/group.

  • b AUC calculated using the linear trapezoidal method up to 1 h.

  • c Ratio of amount of total OH ATV formed to amount of ATV retained in liver at 1 h.

  • d Biliary clearance (quotient of the cumulative amount of ATV excreted into bile and the ATV AUC).

  • e Ratio of amount of ATV in bile to that in liver at 1 h.

  • f Ratio of amount of total OH ATV in bile to that in liver at 1 h.
