Figure 3. Mean limb surface temperature (MLST) (°C) as a result of the interaction between treatment and time. Administration of anesthetic or phosphate buffered saline (PBS) had no significant effect on MLST over time (P . 0.05). LA = left forelimb with anesthetic injection, RA = right forelimb with anesthetic injection, LS = left forelimb with PBS injection, RS = right forelimb with PBS injection.
