| 摘 要： | 前期研究表明粉防己碱增强戊巴比妥钠诱导的催眠作用与5-HT系统相关。本研究采用戊巴比妥钠（45 mg/kg,i.p.）诱导的小鼠翻正反射消失和恢复实验方法,对粉防己碱与不同5-HT受体在增强戊巴比妥钠诱导睡眠中的相互作用进行了探讨。结果表明粉防己碱分别与选择性5-HT1A受体拈抗剂p-MPPI（1 mg/kg,i.p.）,选择性5-HT2A/2C受体拮抗剂ketanserin（1.5 mg/kg,i.p.）合用可以显著增强戊巴比妥钠诱导的催眠作用。选择性5-HT1A受体激动剂8-OH-DPAT（0.1 mg/kg,s.c.）或5-HT2A/2C受体激动剂DOI（0.2mg/kg,i.p.）能够显著减少戊巴比妥钠诱导的小鼠睡眠时间,而粉防己碱（60 mg/kg,i.g.）可以显著拮抗这种睡眠抑制作用。此结果提示,粉防己碱增强戊巴比妥钠诱导的催眠作用可能与5-HT1A受体和5-HT2A/2C受体有关。

| Abstract: | It has been reported that augmentative effect of tetrandrine on pentobarbital hypnosis in mice may be related to serotonergic system. The present study was undertaken to investigate the interaction of tetrandrine and different 5-HT receptors on pentobarbital-induced sleep by using the loss-of-righting reflex method. The results showed that augmentative effect of tetrandrine on pentobarbital hypnosis in mice were potentiated by the p-MPPI （5-HT1A receptor antagonist） （1 mg/kg, i.p.） and ketanserin （5-HT2A/2C receptor antagonist） （1.5 mg/kg, i.p.）, respectively. Pretreatment with either 8-OH-DPAT （5-HT1A receptor agonist） （0.1 mg/kg, s.c.） or DOI （5-HT2A/2C receptor agonist） （0.2 mg/kg, i.p.） significantly decreased pentobarbital-induced sleep time, and tetrandrine （60 mg/kg, i.g.） significantly reversed this effect. These results suggest that both the 5-HTLA and 5-HT2A/2C subfamily may be involved in the potentiating mechanism of tetrandrine＇s effects on pantobarbital hypnosis. |
