(A) Effect of ethynyl estradiol (1.25, 2.5 or 5 µg/rat; −48 h before the test; n = 7–9 per group); and (B) citalopram (1.25, 2.5; 5.0 or 10 mg/kg; −23, −5, −1 h before the test; n = 6–8 per group) at one or three weeks after ovariectomy in the forced swim test. The data represent the mean ± S.E.M. of the number of immobilities scored in intervals of 5-s during a 5-min test session. Holm-Sidack test * p < 0.05; ** p < 0.005 versus respective control group; ^&& p < 0.005 versus three weeks.
