Abstract:

Paeoniflorin has been shown to effectively relieve neurologic impairments and lessen depression. It remains poorly understood whether it can be used to treat menopause depression; therefore, in the present study, animal model of menopause depression were established by resecting the ovaries in combined with long-term chronic unpredictable stress. Animal model of menopause depression was established by ovariectomy. Sprague-Dawley rats were given 10 mg/kg of paeoniflorin by gastrogavage for 2 weeks. Fluoxetine (2.5 mg/kg) served as a positive control. Sucrose solution consumption test, open-field test, real-time PCR and western blot results demonstrated that paeoniflorin increased sucrose solution consumption, voluntary behaviors and 5-HT1AR mRNA and protein expression. Paeoniflorin decreased the levels of corticotropin releasing hormone (CRH), adrenocorticotropic hormone (ACTH), cortisol (CORT) and 5-HT2AR mRNA and protein expression in rats with menopause depression. These results indicate that paeoniflorin unregulated 5-HT1AR expression, but downregulated 5-HT2AR expression in brains of rats with menopause depression, and thus exert antidepressant effects.
