A variety of animal models have been developed to study the effect of antiepileptic drugs. These models provide the means of inducing changes and causing alterations in neural function which may lead to epileptogenesis. Kindling is a lasting change in brain function caused by repeated stimulation resulting an increased seizure duration and progressive intensification of seizure activity. The ki...

AIM To investigate the effects and mechanism of succinic acid on pentylenetetrazol (PTZ) chemical kindling and amygdala electrical kindling in rats. METHODS PTZ chemical kindling and amygdala electrical kindling models were established in rats. The effects of succinic acid on the behavior and afterdischarge of kindled rats were observed. The mice were pretreated with succinic acid, 30 min lat...

background: regarding the prevalence of epilepsy in human society and with respect to inefficiency of the usual treatments, finding new strategies and methods for the medical treatment of epileptic patients are essential. henbane seed has been used in iranian traditional medicine as an anti-convulsion herb. with this regard the present study was carried out to consider the anti-convulsive effec...

background and objective: regarding the prevalence of epilepsy in human society and with respect to insufficiency of usual treatments, new strategies and methods for medical treatment of epileptic patients are necessary. as nmda receptor antagonists are the most prominent anti-epileptic drugs, in the present study, we synthesized and investigated anti-epileptic effect of a new piperidine deriva...

epilepsy is one of the common disorders in human community. clinical observations have shown that epileptic patients have often difficulty in learning and memory. kindling is a laboratory model for studying epilepsy and its complications. this experiment was designed to study the effect of chemical kindling on schaffer collateral-ca1 pyramidal cell synaptic transmission using pentylenetetrazole...

In many alcoholics, the severity of withdrawal symptoms increases after repeated withdrawal episodes. This exacerbation may be attributable to a kindling process. Kindling is a phenomenon in which a weak electrical or chemical stimulus, which initially causes no overt behavioral responses, results in the appearance of behavioral effects, such as seizures, when it is administered repeatedly. Bot...

iintroduction: repetitive transcranial magnetic stimulation (rtms) modulates the excitability of cortical neural networks. the effect of rtms on excitability of cortical networks depends on its frequency. according to the previous reports, a distinction is made between low (<1hz) and high frequencies of rtms. low frequencies of rtms inhibit seizure but high frequencies increase it. in the curre...

Repeated administration of pentylenetetrazol (PTZ 30 mg/kg, thrice a week) to mice for 9 weeks and subsequent challenge of the animals with the same dose of PTZ on the last chronic dose produced chemical kindling. The mice showed myoclonic jerks, clonus, Straub’s tail, falling back response and full-blown convulsions. The anticonvulsant profile of chronic administration of BR16A (100 and 500 mg...

Kindling, a sub threshold chemical or electrical stimulation, increases seizure duration and enhances accompanied behavior until it reaches a sort of equilibrium state. The present study aimed to explore the effect of curcumin on the development of kindling in PTZ kindled rats and its role in apoptosis and neuronal damage. In a PTZ kindled Wistar rat model, different doses of curcumin (100, 200...
