The role of nitric oxide (NO) in epileptogenesis was studied in pentylenetetrazole (PTZ)-treated animals using in vivo and ex vivo EPR spectroscopy. NO generation was measured directly in the brain of a PTZ-induced mouse in vivo by an L-band EPR spectrometer. An elevation in NO production in the brain was observed during convulsions, and more NO was generated in the tonic seizure vs. the clonic...

OBJECTIVE Previously, analgesic, hypnotic, and anticonvulsant effects have been suggested for Rosa damascena (R. damascena). In the present study, possible anti-seizure and neuro-protective effects of hydro-alcoholic extract of R. damascena has been investigated after inducing seizures in rats by pentylenetetrazole (PTZ). MATERIALS AND METHODS The rats were divided to five groups: (1) CONTROL...

OBJECTIVE Coriandrum sativum (C. sativum) as a medicinal plant has been pointed to have analgesic, hypnotic and anti-oxidant effects. In the current study, a possible preventive effect of the hydro-alcoholic extract of the plant on neuronal damages was examined in pentylenetetrazole (PTZ) rat model of seizure. MATERIALS AND METHODS Forty male rats were divided into five main groups and treate...

We have previously proven that some synthetic kynurenines behave as antagonists of the N-methyl-d-aspartate receptor inhibiting neuronal subtype of nitric oxide synthase activity. We now investigate the anticonvulsant activity of four of these kynurenines in pentylenetetrazole (PTZ)-treated rats. The rats were treated with each kynurenine (10-160 mg/kg, s.c.) 30 min before PTZ administration (1...

This study evaluated the alteration of CaMKII autophosphorylation and distribution in rat brain following a single, brief pentylenetetrazol (PTZ) seizure and during PTZ kindling. Total CaMKII alpha subunit (alpha-CaMKII) and alpha-CaMKII phosphorylated at Thr(286) were detected by immunoblot. A large decrease in CaMKII Thr(286) phosphorylation, as well as CaMKII translocation from particulate t...

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...

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...

T association of seizures with anesthetic agents has been a long debate and controversy for decades. There are several anesthetic agents that show seizure like activity after induction such as fentanyl, lignocaine, propofol, sevoflurane, and so forth. Among these agents, there are several reports of propofol, which is very frequently used as an anesthetic induction agent in India, and further a...

objective(s): febrile seizures (fs) are the most common type of convulsive events among children. its prevalence has been estimated to be 2-5% in children between 3 months and 5 years old. also, blood and csf magnesium levels have been demonstrated to be reduced in children with fs. this study investigates the effect of mgso4 pretreatment on the behaviors caused by hyperthermia (ht) and effect ...

Introduction: There is evidence that diabetes affects seizure susceptibility. Ginger (Zingiber officinale Roscoe) which is used in traditional medicine has antioxidant activity and neuroprotective effects. The aim of this study was to evaluate the seizure threshold induced by pentylenetetrazole (PTZ) in diabetic mice after induction of diabetes with streptozocin and to examine the possible ...
