Figure 2.

Dose-related responses to noxious heat (A) and mechanical stimuli (B) at 15 min after IT administration of quinpirole and sulpiride.

Notes: (a) Before plantar incision and (b) IT administration in the saline group. Between-group statistical comparisons were performed using one-way analysis of variance followed by Bonferroni’s post hoc test. Data are expressed as means ± standard deviation (n=10, *P<0.05 vs saline, ^#P<0.05 vs sulpiride).

Abbreviation: IT, intrathecal; min, minutes; s, seconds.
