results the i/r group showed a significant increase in pycnotic (dying) neurons and pretreatment with wc at doses of 500 mg/kg and 1000 mg/kg significantly reduced pycnotic and tunel positive neurons, in a dose dependent manner in ischemic brain cortex. conclusions our findings indicated that wc has neuroprotective effects and is able to reduce histopathological alterations and apoptosis in bra...

aim: oxidative stress plays a crucial role in the pathophysiology of ischemic stroke. since water-solublefullerene derivatives act as the potent scavenger of oxygen free radicals in biological systems, we aimedto investigate the possible protective effects of fullerol nanoparticles on brain infarction and edema intransient model of focal cerebral ischemia in rat.materials & methods: experiment ...

The arterial supply of the feline motor cortex is derived from both the anterior and middle cerebral arteries. The anterior cerebral artery supplies most of cortical area 6 (premotor cortex), the intrafundal cruciate and medial postcruciate cortex, (hindlimb motor cortex), and the midline and medial portions of the sensory areas 3a-7. The middle cerebral artery supplies the lateral prorean cort...

Following a single administration of sodium thiopental in high doses (85 mg/kg intraperitoneally), the animals demonstrated absence or weakening reflexes at levels spinal cord, medulla oblongata, bridge and midbrain cerebral cortex over period one day. Other signs included pronounced hypothermia, decrease respiratory rate violation its rhythm, distinct tendency to bradycardia. On days 1-3 after...

Malformations of the cerebral cortex are often causes epilepsy. The latest changes in their classification summarized. description lissencephaly and Miller–Dicker syndrome, pachygyria, polymicrogyria, hemimegaloencephaly, holoprosencephaly, schizencephaly, gray matter heterotopia is given. features epilepsy these diseases described. Magnetic resonance imaging scans for focal cortical dysplasia,...

background: it has been suggested that organophosphates may inhibit gamma-aminobutyric acid (gaba) metabolism in synaptosomal preparations. in the present investigation, we have assessed the interaction between paraoxon and the gaba system at synaptic level.   methods: synaptosomes were prepared from male wistar rats (200-250 g). cerebral cortex was dissected and homogenized, then centrifuged a...

INTRODUCTION  In the literature, the incidence of oropharyngeal dysphagia in patients with cerebrovascular accident (AVE) ranges 20-90%. Some studies correlate the location of a stroke with dysphagia, while others do not. OBJECTIVE  To correlate brain injury with dysphagia in patients with stroke in relation to the type and location of stroke. METHOD  A prospective study conducted at the Ho...
