title: Imipramine administered during an infantile period modifies sex difference in L-5-hydroxytryptophan-induced head shakes in rats.
abstract: Five mg/kg imipramine or desipramine was injected to infantile rats. L-5-Hydroxytryptophan-induced head shakes were assessed when rats were mature. The saline- and desipramine-treated adult male rats exhibited more sustained response to L-5-HTP than females. The time course of the head shake frequency in the imipramine-treated male and female rats showed a pattern between control males and females, resulting in no significant sex difference. The results suggest that infantile exposure to imipramine induces an alteration of the serotonergic neurons of the brain.
