Abstract
Objective and Methods : This study was performed to evaluate the anticonvulsant, antioxidant effect of modified formulas Korean traditional medicine Cheongsinhwadam-Jeon(CSHDJ). The extract of CSHDJ was administered (p.o.) to mice for 14 days in anticonvulsant and antioxidant tests. Results : The pretreatment of CSHDJ extract prohibited pentylenetrazol (PTZ)-induced convulsion. In PTZ-induced convulsion, lowered level of brain ${\gamma}$-aminobutyric acid(GABA) was restored normal state by the pretreatment of CSHDJ. Increased level of brain glutamic acid was lowered to normal state by CSHDJ, and increased activity of brain ${\gamma}-aminobutyric$ acid transaminase(GABA-T) was reduced to normal state by CSHDJ. In PTZ-induced convulsion, increased level of brain lipid peroxide was lowered to normal state by the pretreatment of CSHDJ. Increased activity of brain xanthine oxidase(XOD) was lowered by CSHDJ, and increased activity of brain aldehyde oxidase lowered to normal state by CSHDJ. In PTZ-induced convulsion, increased activities of superoxide dismutase(SOD) and catalase in brain were lowered by the pretreatment of CSHDJ, whereas increased level of glutathione and increased activity of gluthathione peroxidase in brain were not changed significantly. Conclusions : Above results suggest that CSHDJ has anticonvulsant, antioxidant effect. That seems to be strongly related with the levels of GABA, glutamate, lipid peroxide and the activities of GABA-T, XOD, aldehyde oxidase, SOD, catalase in brain tissue. From these results, CSHDJ could be applied to various convulsive disorders.
