Kainic acid (KA) is a excitatory agonist causing epileptic seizure and excitotoxicity in the hippocampus. Gastrodia Elata (GE) is known to have anti-convulsant and anti-oxidant effects. This study was investigated a possible role of GE in suppressing epileptic seizure using KA-induced epilepsy mouse model. Eight-week-old male C57BL/6 mice were administrated GE (50 or 500 mg/kg) once a day for 5 days, and then injected KA (30 mg/kg) intraperitoneally. Behavioral changes in mice by KA were evaluated for 90 minutes immediately after the KA administration. Six hours after the KA administration, their brains were harvested and the expressions of glutamate decarboxylase 67 (GAD-67) and K+-Cl- cotransporter 2 (KCC2) in the hippocampus of the mice were measured by immunohistochemistry.GE delayed the onset of epileptic seizure after KA administration, suppressed the severity of the seizure and decreased the number of severe seizures dose dependently. Moreover, GAD-67 and KCC2 expressions in the cornu ammonis (CA) 1 and CA3 of 500 mg/kg GE administrated mice were significantly increased compared to those in KA-treated mice.GAD-67 and KCC2 play an important role in regulating GABAergic system. Our results suggest that GE has anti-convulsant effect against KA-induced epileptic seizure through enhancing GABAergic system.
