In the present study, we investigated the effect of kamishoyosan (KSS) on conditioned fear-induced freezing in ovariectomized (OVX) rats. Socially isolated OVX rats showed the longest freezing time among the following four groups: group-housed sham-operated (Sham), isolated Sham, group-housed OVX, and isolated OVX rats. Repeated oral administration of KSS (30-300 mg/kg) reduced conditioned fear-induced freezing in socially isolated OVX rats. The reduction of freezing by KSS was reversed by flumazenil (3 mg/kg) and bicuculline (3 mg/kg). These findings suggest that the GABAA-benzodiazepine receptor complex is involved in the anxiolytic effect of KSS in socially isolated OVX rats.
在本研究中，我们调查了加味逍遥散（KSS）对去卵巢（OVX）大鼠条件性恐惧诱导的僵住反应的影响。在以下四组大鼠中，社会隔离的OVX大鼠表现出最长的僵住时间：群居假手术（Sham）组、隔离假手术组、群居OVX组和隔离OVX组大鼠。对社会隔离的OVX大鼠重复口服KSS（30 - 300毫克/千克）可减少条件性恐惧诱导的僵住反应。氟马西尼（3毫克/千克）和荷包牡丹碱（3毫克/千克）可逆转KSS对僵住反应的降低作用。这些发现表明，GABAA-苯二氮䓬受体复合物参与了KSS对社会隔离的OVX大鼠的抗焦虑作用。
