The effect of cabergoline and levetiracetam on the histological and stereological structure of the cerebellar cortex, hippocampal and cerebellum in a model of PTZ-induced seizure kindling in rats
Background: Seizure is a chronic neurological disease that may have non-neurological origins such as astrocytes and microglia. Objective: The aim of this study was to investigate the effect of alone and co-administration of cabergoline and levetiracetam on the histological and stereological structure of the cerebral cortex, hippocampus and cerebellum following chronic seizures in rat. Methods...
متن کاملMorphometrical Study of Polysialylated Neural Cell Adhesion Molecule Positive Cells in Rat Pups Hippocampus Following Induction of Seizure during Pregnancy
Background:The polysialylated neural cell adhesion molecule (PSA-NCAM) is expressed in developing brain. Fetal brain damage is caused by different conditions such as seizure and hypoxia. The present study was designed to investigate the effect of maternal seizures on the number of PSA-NCAM positive cells in pup's hippocampus. Methods: Female Wistar rats were divided into four groups: (a) kindle...
متن کاملEffect of Ocimum basilicum hydro-alcoholic extract on oxidative damage of brain tissue following seizures induced by pentylenetetrazole in mice
Introduction: A relationship between epileptic seizures and brain tissue oxidative damage has been suggested. Ocimum basilicum (O. basilicum) has been shown to have beneficial effects including hypnotic and protective against tissue oxidative damage. The present study was designed to evaluate the effects of O. basilicum hydro-alcoholic extract on oxidative damage of brain tissue following s...
متن کاملImmunocytochemistry of neuron specific enolase (NSE) in the rat brain after single and repeated epileptic seizures.
The aim of this study was to investigate neuron-specific enolase (NSE) immunoreactivity of the different brain regions after pentylenetetrazol (PTZ)- induced epileptic seizures in rats. Light microscopic examinations provided evidences for changes of neuronal activity after single and repeated seizures. The number of NSE (+) cells was well correlated with Nissl staining. The results suggest tha...
متن کاملElectrophysiological characteristics of hippocampal CA1 neurons after spreading depression-triggered epileptic activity in brain slices
Introduction: A close link between spreading depression (SD) and several neurological diseases such as epilepsy could be demonstrated in many experimental studies. Epilepsy is among the most common brain disorders. Despite a large number of investigations, its mechanisms have not been yet well elucidated. Hippocampus is one of the important structures involved in seizures. The aim of this st...
