  • Objective : This study was performed to investigate the agonistic activity of Chunmajeongal-tang extract to the $GABA_A/benzodiazepine$ receptor complex. Methods : Male mice and Sprague-Dawley rats were used for this experiment. Chunmajeongal-tang Prescription was extracted with 80% methanol, evaporated in vacuo and dried with freeze dryer. The agonistic activity to the GABA/ benzodiazepine receptor complex and GABA transaminase activity were measured in vitro. Results : Chunmajeongal-tang extract inhibited dose-dependently the binding of [3H]Ro15-1788, an antagonist on GABA/benzodiazepine receptor complex, in rat cerebral cortices, showing $82.4{\pm}4.12%$ inhibition at a dose of 5.0 mg/kg. This extract inhibited dose-dependently the binding of [3H]flunitrazepam, an agonist on GABA/benzodiazepine receptor complex, in rat cerebral cortices, showing $5.6{\pm}1.24%$ inhibition. Furthermore, Chunmajeongal-tang extract inhibited the binding of [3H]flunitrazepam in the presence of GABA/NaCI with $13.2{\pm}0.44%$ inhibition, its inhibitory effect exhibited a positive GABA shift, which means that this extract activates a GABAergic neurotransmission.
