Fig. 1 — Rolipram decreased self-administration of ethanol, but not sucrose or water. Rolipram (0.0125–0.05 mg/kg, s.c.) was administered 30 min before the start of the session. Rolipram at 0.025 and 0.05 mg/kg significantly reduced lever presses for 5% ethanol (A), but not those for 10% sucrose (B). Rolipram at any of the doses did not affect water responses when ethanol (C) or sucrose (D) was provided. The data are expressed as mean lever presses ± SEM (one-way ANOVA followed by Bonferroni post hoc test). *, p < 0.05; **, p < 0.01 compared to with NS (0 mg/kg rolipram); n = 6.
