Introduction: the plant Mucuna pruriens is traditionally used in Indian system ofmedicine for therapy of several neurological disorders. Chemical investigationson have established presence levodopa and tryptamine which areresponsible treating disorders like Parkinsonism. Objective:the objective this research was to scientifically explore ascertain its antiepilepticand anxiolytic activity precli...

AIM The changes of seizure susceptibility of transgenic mice overexpressing GABA transporter-1 (GAT-1) were studied to clarify the possible role of GABAergic transmission in epileptogenesis. METHODS Seizures were induced by intraperitoneal administration of pentylenetetrazol (PTZ), picrotoxin (PIC), or kainic acid (KA) respectively. The anticonvulsant effect of ethyl nipecotate was tested by ...

DBA/2J (D2) and C57BL/6J (B6) mice exhibit differential sensitivity to seizures induced by various chemical and physical methods, with D2 mice being relatively sensitive and B6 mice relatively resistant. We conducted studies in mature D2, B6, F1, and F2 intercross mice to investigate behavioral seizure responses to pentylenetetrazol (PTZ) and to map the location of genes that influence this tra...

Epileptic activity is generally induced in experimental models by local application of epileptogenic drugs, including pentylenetetrazol (PTZ), widely used on both vertebrate and invertebrate neurons. Despite the high prevalence of this neurological disorder and the extensive research on it, the cellular and molecular mechanisms underlying epileptogenesis still remain unclear. In this work, we e...

Epilepsy is a chronic neurological disorder characterized by recurrent seizures. However, approximately one-third of epilepsy patients still suffer from uncontrolled seizures. Effective treatments for epilepsy are yet to be developed. N (6)-(3-methoxyl-4-hydroxybenzyl) adenine riboside (B2) is a N(6)-substitued adenosine analog. Here we describe an investigation of the effects and mechanisms of...

Transient receptor potential vanilloid 1 (TRPV1) is widely distributed in the central nervous system (CNS) including hippocampus, and regulates the balance of excitation and inhibition in CNS, which imply its important role in epilepsy. We used both pharmacological manipulations and transgenic mice to disturb the function of TRPV1 and then studied the effects of these alterations on the suscept...

Effects of repeated postnatal administration of caffeine (10 and 20mg/kg s.c. daily from P7 to P11) were studied in two models of epileptic seizures characterized by spike-and-wave EEG rhythm in 18- and 25-day-old rats. Rhythmic metrazol activity (RMA, model of human absences) was induced by low dose of pentylenetetrazol (PTZ, 20mg/kg or 40mg/kg, i.p.) and minimal clonic seizures (model of huma...

Objective: Plant extracts are of considerable interest because of their antiepileptic activities. However, the mechanisms of action are not clearly defined. Materials and Methods: Here, the effects of Artemisia dracunculus L. (tarragon) leaves extract on excitability and electrophysiological characteristics of snail neurones were investigated, using an intracellular recording technique. Results...

In this paper numerous alternative treatments in addition to pharmacological therapy are proposed for their use in epileptic patients. Epileptic animal models can play a crucial role in the performance evaluation of new therapeutic techniques. The objective of this research is to first develop various epileptic rat models; second, develop a portable wireless closed-loop seizure controller inclu...
