Effects of subcutaneously administered rolipram (a) and S-petasin (b) on the duration of xylazine (10 mg/kg, i.p.)/ketamine (70 mg/kg, i.p.)-induced anesthesia in mice. Rolipram or S-petasin was administered 15 min or 1 h before anesthesia, respectively. , compared to the vehicle (control). Each value represents the mean ± SEM. The number of each group was 5–11.
