Norfloxacin-induced electroencephalogram alteration and seizures in rats are not triggered by enhanced levels of intracerebral glutamate.

چکیده
Pharmacokinetic-pharmacodynamic modeling of the electroencephalogram (EEG) effect was combined with intracerebral glutamate determinations using microdialysis for rats receiving norfloxacin intravenously (150 mg/kg of body weight). The EEG effect (accompanied by tremors and seizures) was consistently observed without glutamate level modifications. Therefore, norfloxacin-inducted seizures are not triggered by intracerebral glutamate level enhancement.

Convulsant and subconvulsant doses of norfloxacin in the presence and absence of biphenylacetic acid alter extracellular hippocampal glutamate but not gamma-aminobutyric acid levels in conscious rats.
Fluoroquinolones are antibiotics with central excitatory side effects. These adverse effects presumably result from inhibition of gamma-aminobutyric acid (GABA) binding to GABA(A) receptors. This GABA antagonistic effect is greatly potentiated by the active metabolite of fenbufen, biphenylacetic acid (BPAA). Nevertheless, it remains questionable whether GABA receptor antagonism alone can explai...
متن کاملBerberine attenuates convulsing behavior and extracellular glutamate and aspartate changes in 4-aminopyridine treated rats
Objective(s): K+ channel blocker 4-aminopyridine (4-AP) stimulates the release of glutamate from nerve terminals and induces seizures. Berberine as a potential herbal drug exerts several pharmacological actions on the central nervous system including anxiolytic, anticonvulsant, and neuroprotective properties. The present study aimed to investigate the effect of berberine on seizure onset and ti...

Background: Glutamate is essential to learning and memory as an excitatory neurotransmitter. This study evaluated the atrazine effect on the hippocampus and examined the mitigative role of avocado oil against the neuronal degeneration and behavioral deficits in Wistar rats. Methods: Fifty adult male Wistar rats were divided into four groups of ten. Group 1 (controls) received 0.5 ml distilled ...
متن کاملAlterations of the electroencephalogram sub-bands amplitude during focal seizures in the pilocarpine model of epilepsy
Introduction: Temporal lobe epilepsy (TLE) is the most common and drug resistant epilepsy in adults. Due to behavioral, morphologic and electrographic similarities, pilocarpine model of epilepsy best resembles TLE. This study was aimed at determination of the changes in electroencephalogram (EEG) sub-bands amplitude during focal seizures in the pilocarpine model of epilepsy. Analysis of thes...

Objective(s): The present study aims to study the alteration of glutamatergic transmission in the dorsal horn neurons and the effect of gabapentin on oxaliplatin-induced neuropathic pain in rats. Materials and Methods: Oxaliplatin (5 mg/kg) or saline was administered to adult male Sprague-Dawley rats. Gabapentin (60 mg/kg, IP) or vehicle was injected daily. Mechanical allodynia was assessed us...
