Effects of maprotiline on the antinociceptive effect of morphine under the UCMS condition. The effects of maprotiline on the thermal pain sensitivity (a) and the antinociceptive effect of morphine (3 mg/kg; b) in a hot-plate test under the UCMS (white column vehicle, n = 12; gray column maprotiline 3 mg/kg, n = 12; black column maprotiline 10 mg/kg, n = 14) and non-stress (white column vehicle, n = 14; gray column maprotiline 3 mg/kg, n = 12; black column maprotiline 10 mg/kg, n = 14) conditions. * p < 0.05, significantly differed from vehicle-injected UCMS mice. Data are expressed as mean ± SEM.
