The effects of rolipram on 3-h (A) and 24-h (B) memory retention in the step-down passive avoidance test in Aβ42-treated mice. Aβ42-induced decreases in 3-h and 24-h retention were reversed by chronic treatment with rolipram for 14 days Values shown are means ± SEM, n = 10; ***p < 0.001 vs. vehicle-treated control group. ###p < 0.001 vs. vehicle-treated Aβ group. $$$p < 0.001 vs. rolipram (1.0 mg/kg)-treated Aβ group.
