The effect of dipentylammonium (DPA, 5 mg.kg−1) and sigma-1 receptor antagonist BD1047 (4 mg.kg−1) on despair behaviour in mice subjected to the forced-swim test. The control consisted of 10 ml.kg−1 saline; fluoxetine (10 mg.kg−1) was used as a positive control. Five mice were used for each data point. Error bars show SEM. ANOVA followed by Bonferroni post hoc multiple comparison gave: *control vs fluoxetine, P 0.0022; **control vs dipentylammonium, P < 0.0001; control vs BD1047, P = 0.13; ##dipentylammonium vs BD1047 + dipentylammonium, P = 0.0001.
