background: the cuprizone multiple sclerosis (ms) animal model is characteristic for toxic demyelination and represents a reversible demyelination and remyelination system. it has been shown that green tea epigallocatechin-3-gallate (egcg) might be effective in improving the symptoms and pathological conditions associated with autoimmune inflammatory diseases in several animal models. objective...
background: alzheimer’s disease (ad) is a neurodegenerative disorder with progressive loss of cognitive abilities and memory loss. the aim of this study was to compare neuropathological changes in hippocampus and brain cortex in a rat model of ad. methods: adult male albino wistar rats (weighing 250-300 g) were used for behavioral and histopathological studies. the rats were randomly assigned t...
background: central renin angiotensin system has an important role on the cerebral microcirculation and metabolism. our previous work showed that inhibition of angiotensin converting enzyme (ace) activity prior to induction of ischemia protected the brain from severe ischemia/reperfusion (i/r) injuries. this study evaluated the impacts of post-ischemic inhibition of ace, enalapril, on brain inf...
Olig1 and Olig2, two transcription factors, play regulatory function in the differentiation and specification of oligodendrocyte progenitor cells (OPCs). In this study the effects of electromagnetic fields (EMF) on total protein concentration ( TPC ) and Olig1 and Olig2 expression in the cerebral cortex of mouse was examined. Twenty-one Balb/c mice were separated into three groups: control, EMF...
in this paper it has been shown that deterioration of the brain cortex capillary system and negative dynamics of cerebral tissue morphology occur under conditions of hypo kinesia. simultaneously, gamma-aminobutyric acid (gaba) and piracetam have been shown to favor the development of vasodilation and prevent further worsening of the cerebral blood supply. during the experiment, it was also esta...
In this study, the effect of topiramate, as an antiepileptic drug, was evaluated on morphine craving in rats. The conditioned place preference (CPP) test was used for this purpose. Repeated administration of morphine (10 mg/kg, i.p. for 4 days) induced significant CPP. Administration of topiramate (50 and 100 mg/kg, i.p. for 4 days) with each morphine administration decreased the acquisition of...
Objective: The present study investigated possible neuroprotective effects of ethanolic extract of Tiliacora triandra leaf against cerebral ischemic-reperfusion injury in mice. Materials and Methods: Forty male Institute of Cancer Research (ICR) mice were randomly divided into five groups: (1) Sham + 10% Tween 80, (2) bilateral common carotid artery occlu...

the variations of glucose 6-phosphate dehydrogenase (g6pd) activity in different brain regions of normal, hypo- and hyperthyroid rats were investigated. hypo- and hyperthyrodism were experimentaly induced by administration of methimazol and liothyronine, respectively. in normal rats, midbrain had the minimum (70 mu/mg) and cerebral cortex the maximum (349 mu/mg) g6pd activity. hyperthyrodism in...
