Epilepsy is a complex neurological disorder that affects around 1%of the world’s population.it affects the neural cells of the CA1 and CA3 regions of the brain's hippocampus that causes behavioral disorders. The use of medicinal herbs for the treatment of epilepsy has long been common, but these effectors have been less successful. According to glutamate theory, the cause of epilepsy is t...

introduction: in this study, the effect of memantine administration into the nucleus accumbens on the metabolic changes induced by acute stress in female mice was evaluated. methods: intra-accumbens unilateral or bilateral canulation was performed. one week after recovery, a group of animals were given memantine (1, 0.5, and 0.1 μg/mouse) five min before stress induction intra-accumbally, and t...

introduction: we previously shown that microinjection of glutamate into the hdb of rat elicited cardiovascular depressive responses. microinjection of ap5 (an nmda receptor antagonist, 2.5 mm, 50 nl) and cnqx (an ampa receptor antagonist, 1 mm, 50 nl) caused no significant changes in the blood pressure and heart rate. microinjection of bicuculline (bmi: a gabaa receptor antagonist, 1 mm, 50 nl)...

Glutamate induces excitotoxic damage to hippocampal pyramidal neurons in Status Epilepticus (SE) and epilepsy. In this study, we investigated time course of dysregulation of calcium homeostasis at various intervals after an episode of SE in acutely isolated CA1hippocampal pyramidal. For this purpose, male Sprague-Dawley rats (200 g) were subjected to pilocarpine-induced SE. The SE was blocked a...

conclusions in the literature, it was observed that short-term msg exposure does not cause significant histological changes in the kidneys, liver, or brain cortex. these findings should be re-evaluated in additional long-term studies. background monosodium glutamate (msg) is a widely-used flavor enhancer and stabilizer in ready-made or packaged foods. the excessive use of msg has been shown to ...

neuroprotective effect of the extract from aerial parts of scrophularia striata boiss(scrophulariaceae) was investigated against glutamate-induced neurotoxicity on cultured rat pupscerebellar granule neurons (cgns). cgns from 8 days old sprague-dawley rat were preparedand cultured. the experiments were performed after 8 days in culture. the plant was collected fromthe northeastern part (ruin re...

long-term potentiation (ltp) is a reflection of synaptic plasticity that induced by specific patterns of synaptic activity and has an important role in learning and memory. the first clue of the potential role of glutamate receptors in ltp was in 1991 with the observation that the mglur agonists 1-amino-1, 3-cyclopentanedicarboxylic acid (acpd), increased ltp. studies have shown that acpd induc...

background: the nucleus raphe magnus (nrm) is involved in thermoregulatory processing. there is a correlation between changes in the firing rates of the cells in the nrm and the application of the peripheral thermal stimulus. introduction: we examined the effect of reversible inactivation and excitation of nrm on mechanisms involved in tail blood flow (tbf) regulation in hypothermia. methods: h...

objective(s) nicotinic acetylcholine receptors (nachrs) regulate epileptiform activity and produce a sustained pro-epileptogenic action within the hippocampal slices. in the present study, we investigated the effect of nachrs on evoked glutamatergic synaptic transmission in area ca3 and ca1 of rat hippocampal slices to identify possible excitatory circuits through which activation of nachrs pro...

Excitotoxicity is likely to occur in pathological scenarios which mitochondrial function already compromised, shaping neuronal responses glutamate. In fact, mitochondria sustain cell bioenergetics, tune intracellular Ca2+ dynamics, and regulate glutamate availability by using it as metabolic substrate. Here, we suggest the need explore toxicity context of specific disease models may ...
