  • Certain dietary contents, biological supplements might influence the occurrence or treatment of epilepsy. Some studies have found that the supplementation with individual nutrients reduced seizure frequency or improved other aspects of health in patients with epilepsy. Potentially beneficial dietary interventions include treating blood glucose dysregulations. Identifying and avoiding allergenic foods, and avoiding suspected triggering agents such as alcohol, aspartame, and monosodium glutamate. The Atkins diet (very low in carbohydrates) is a less restrictive type diet that may be effective in some cases. Nutrients that may reduce seizure frequency include vitamin B6, magnesium, vitamin E, manganese, taurine, dimethylglycine, and omega-3 fatty acids. Administration of thiamine may improve cognitive function in patients with epilepsy. Supplementation with folic acid, vitamin B6, biotin, vitamin D, and L-carnitine may be needed to prevent or treat deficiencies resulting from the use of anticonvulsant drugs. Vitamin K1 has been recommended near the end of pregnancy for women taking anticonvulsants. Melatonin may reduce seizure frequency in some cases, and progesterone may be useful for women with cyclic exacerbations of seizures. In most cases, nutritional therapy is not a substitute for anticonvulsant medications. However, in selected cases, depending on the effectiveness of the interventions, dosage reductions or discontinuation of medications may be possible. However, nutrient supplementation may be necessary to prevent or reverse the effects of certain deficiencies that frequently result from the use of antiepileptic drugs.

  • Epileptifrom discharges were induced in the telencephalon of the adult zebrafish via perfusion with pentylenetetrazole (PTZ), bicuculline methiodide, kainic acid-treated artificial cerebrospinal fluid (aCSF), and $Mg^{2+}$-free aCSF. Ginseng total saponin [GTS ($50{\mu}g/ml$)] was shown to attenuate the occurrence rate of epilpetiform discharges by 50-75%, compared to the control. Ginsenoside $Rg_1$ ($130{\mu}M$) reduced the epileptiform discharges in the isolated telencephalon and delayed the occurrence of behavioral seizures observed from the adult zebrafish placed in the PTZ (10 mM)-containing aquarium water. However, Re was not effective in the suppression of epileptiform discharges and behavioral seizures. These results indicate that $Rg_1$ may be useful in the control of epileptiform discharges and effective in controlling behavioral seizures, and that the zebrafish can be used as a model animal for the testing of potential anticonvulsant drugs.

  • Gastrodia elata is a medicinal plant which has been used as anticonvulsant in Korea, Japan and China. This study was conducted to examine the action mechanism of Gastrodia elata centering around the change of GABA and glutamic acid level in brain while observing the anticonvulsive effect in PTZ-induced seizure model. Seizures were reduced effectively by pretreatment of ether soluble part of methanol extract of Gastrodia elata. The pretreatment of ether soluble part inhibited not only the decrease of brain GABA level but also the increase of brain glutamic acid level observed in PTZ model of convulsive dose. Although there was not any change in glutamic acid level, the same development was also observed in the model of subconvulsive dose. From above results, it seems that the anticonvulsive component of Gastrodia elata is lipophilic, and its action mechanism is originated from both control action of GABA level and inhibition of glutaminergic neurotransmission.

  • In order to find active ingradients having an agonistic activity to benzodiazepine receptor from Gastrodia elata Blume (Orchidaceae) which has been used as an anticonvulsant in oriental medicine, one component and some fractions were separated from the butanol extract of the rhizomes of this plant and evaluated for their activities on GABA/benzodiazepine receptor in vitro. As a result, one crude mixture (F4f) obtained from the most active fraction (F4) inhibited significantly the binding of $[^3H]Ro15-1788$, a selective benzodiazepine receptor antagonist, to benzodiazepine receptor of rat cortices. GABA significantly enhanced the inhibition of $[^3H]flunitrazepam$ binding by F4f, and this positive GABA shift supported the strong possibility of the agonistic activity of F4f to benzodiazepine receptor.

  • Although the first pyridazine was obtained in 1886, this heterocycle was not thoroughly investigated such isomers as pyrimidine and pyrazine especially in the field of drug development because pyridazine derivatives do not occur as natural products. Recently medicinal chemists have an growing interest in the pyridazine derivatives, since many Pyridazine derivatives were found to possess various potential therapeutic activities. In this paper sixty-eight pyridazine derivatives, which are already introduced as medicines or are being developed as drugs were classified according to their pharmacological activities, reviewed since 1955 and the relationship of structure-activities was discussed.

  • This study aimed to synthesize new anticonvulsive agents as potential dual acting prodrugs. For the synthesis of ester or amide prodrug types, p-hydroxybenzaldehyde or valproic acid was coupled with clinically usable anticonvulsants or GABAmimetics with use of DCC/DMAP coupling methods. Also their anticonvulsive activities were evaluated.

  • Brazilin is the phenolic compound isolated from the Caesalpinia sappan. This compound has shown a wide range of physiological properties, such as hypoglycemic, anticonvulsant, vasorelaxing, and immunomodulating effects. In this study, we have found that brazilin induced DNA strand scissions in the presence of Cu(II) and this DNA cleavages were mediated by reactive oxygen species. (omitted)

  • Currently convulsion is considered to be a chronic central nerve disease characterized by involuntary and severe muscle contraction or spasm. In many recent studies, convulsion's mechanism is due to unbalance between stimulation and suppression of the central nerve system, such as GABA and glutamic acid. Objectives : This study was performed to examine the anticonvulsant effects of Podam-hwan on brain GABA levels and glutamate content in picrotoxin-induced convulsions and to determine the inhibitory activity on GABA transaminase. Methods : Brain GABA levels and glutamate content in the brains of picrotoxin-induced mice using reverse phase HPLC method, anticonvulsant effect in vivo, and the inhibitory effect on GABA transaminase activity in vivo have been investigated. Results : Podam-hwan significantly lengthened the onset time of picrotoxin-induced convulsion at a concentration of 15mg/kg, but did not show a dose-dependent pattern. Also, Podam-hwan shortened the duration of convulsion by 52.2% at a dose of 30mg/kg in comparison with the control group. Podam-hwan inhibited dose-dependently GABA transaminase activity by 35.5% at 30mg/kg, comparing with the control gmup. Podam-hwan also increased the brain GABA level by 38.7% and 68.8% at doses 15mg/kg and 30mg/kg, respectively. In addition, Podam-hwan decreased the brain glutamate level by 9.6% and 17.8% at doses 15mg/kg and 30mg/kg, respectively. Conclusions : Podam-hwan can be prescribed for the treatment of convulsion by enhancement of brain GABA level and inhibition of GABA transaminase activity.
