    Selective serotonin reuptake inhibitors and serotonin/norepinephrine reuptake inhibitors are widely used to treat mood and anxiety disorders. Aconiti tuber (AT) is traditionally used to alleviate the psychological disorders in the Oriental medicine. The purpose of this study was to characterize the putative anxiolytic-like effect of the 'ethanol extract of AT' (ATE) using elevated plus-maze (EPM) in mice. We further evaluated whether ATE had the modulatory property of serotonin and norepinephrine using [³H]paroxetine and [³H]nisoxetine binding assay and [³H]norepinephrine uptake assay. In EPM test, intraperitoneal pretreatment of ATE (1 ㎎/㎏) significantly increased the time spent into the open arms compared with the control group. In addition, ATE inhibited the specific binding of [³Hlnisoxetine (selective ligand for norepinephrine transporter) and [³H] norepinephrine uptake in concentration dependent manner. However, ATE did not show any affinity for serotonin transporters in the [³H]paroxetine binding assay. Therefore, these results suggest that ATE may produce anxiolytic-like effect by the selective modulation of norepinephrine reuptake in the central nervous system.
