摘要
Affective disorders are more common in women. The forced swim test acts like a depressive stimulus. Hippocampus and frontal cortex 5-HT1A receptors of female and male Wistar rats subjected to the forced swim test were compared with a sham group. The forced swim test diminishes (P < 0.05) the hippocampus H-3-80H-DPAT bound in the female rats (184 +/- 16 fmol/mg protein) with respect to the male rats (309 +/- 41 fmol/mg protein) and to the female sham rats (255 +/- 20 fmol/mg protein). The forced swim test increases the frontal cortex 5-HT1A receptors in the female rats with respect to the female sham group (40.4 +/- 5 versus 24.7 +/- 4 fmol/mg protein, P < 0.05). An increased sensibility of the 5-HT1A receptors to depressive-stimulus may be one mechanism underlying the higher prevalence of depression in female. (C) 2003 Elsevier Ireland Ltd.
