  • * Values are mean ± SD; n = 4 per animal.

  • Significantly different between the 2 baboons (unpaired t test; P < 0.05).

  • Significantly different from values derived with kinetic analysis (paired t test; P < 0.05).

  • § Significantly different from values derived with kinetic analysis (paired t test; P < 0.001).
