Abstract

Introduction: FENNEL is rich in phytoestrogens and is used for estrogen deficiency disorders. Estrogens affect ANXIETY through neurochemical systems such as GABA-A receptors. In this study the effects of FENNEL on GABA-A and estrogen receptors in ANXIETY were investigated.Methods: Adult female Wistar rats weighing (180±20 g) were divided into 8 groups. Groups received saline, FENNEL (200, 500, 750 mg/kg), TAMOXIFEN (15 mg/kg) +fennel (500 mg/kg), PICROTOXIN (1 mg/kg) +fennel (500 mg/kg). A control group was also used. ELEVATED PLUS MAZE was used for evaluation of ANXIETY by measuring the time spent in the open arm. All drugs were administered intraperitoneally.Results: The results showed that FENNEL only at the dose of 500 mg/kg had significant anxiolytic effects and increased the time spent in open arms (P<0.01). PICROTOXIN (GABA-A antagonist) significantly prevented anxiolytic effect of 500 mg/kg of FENNEL (P<0.001). TAMOXIFEN, an estrogen receptor antagonist, also abolished the anxiolytic effect of FENNEL (P<0.001).Conclusion: FENNEL reduced ANXIETY in rats and PICROTOXIN, a non-competitive antagonist of GABA-A receptors, as well as TAMOXIFEN, an antagonist/agonist of estrogen receptors, reduced this anxiolytic effect. Thus FENNEL as a herbal drug seems to have an anxiolytic effect and it probably acts through GABA-A and estrogen receptors.
