Effects of treatments on body temperatures.

		Body temperature (°C)
Group	Body weight (g)	Pre	Post	Change (°C)
Vehicle	332 ± 3	37.8 ± 0.1	37.8 ± 0.1	+0.02 ± 0.09
NLX – 1.5 mg/kg	330 ± 4	37.9 ± 0.1	37.8 ± 0.1	−0.05 ± 0.08
NLXmi – 1.5 mg/kg	328 ± 3	37.7 ± 0.1	37.8 ± 0.1	+0.04 ± 0.10
NLXmi – 1.5 mg/kg	334 ± 2	37.8 ± 0.1	37.8 ± 0.1	+0.03 ± 0.06

Data are presented as mean ± SEM. NLX, naloxone. NLXmi, naloxone methiodide. There were 6 rats in each group. There were no between-group differences in body weights or body temperatures (P > 0.05, for all comparisons). None of the treatments affected baseline body temperatures (P > 0.05, for all comparisons).
