epilepsy/hypoxia

The article concerns the usage of discrete normobaric hypoxic therapy as a way to enhance non-specific resistance in epilepsy treatment. The optimising effect of hypoxia on physiological functions of the patients with epilepsy consists in an increase of haemoglobin and erythrocytes in blood, less

The article reviews the factors of abiotic and biotic environments liable to provoke convulsions. An assumption is made that the common element of their action on the organism are hypoxic states of varying types and depth. Animals with high individual tolerance of acute hypoxia were found to possess

Infant monkeys have been subjected to hypoxia with an arterial pO2 of 20-22 Torr for 30 min. Following perfusion 1-2 weeks later electron microscopy of the motor cortex shows a selective degeneration of axon terminals making symmetrical synapses and which probably arise from inhibitory GABAergic

The experiments were designed to study the glutamate gene expression during epilepsy in adult and hypoxic insult to brain during the neonatal period and the therapeutic role of neuroprotective supplements. We investigated the role of metabotropic glutamate-8 receptor (mGluR8) gene expression in

Influence of cerebral hypoxia and hyperventilatory hypocapnia on the ECoG and focal epileptiform activity of the cerebral cortex induced with local application of strychnine was studied in cats with transection of spinal cord at C1. Although both hypoxia and hypocapnia produced synchronization of

Numerous animal models of epileptogenesis demonstrate neuroplastic changes in the hippocampus. These changes occur not only for the mature neurons and glia, but also for the newly generated granule cells in the dentate gyrus. One of these changes, the sprouting of mossy fiber axons, is derived

A potent sound stimulation induces in Krushinskiĭ-Molodkina rats epileptiform seizures associated with increased blood levels of stressor hormones and subdural hemorrhages in the brain. Adaptation to periodic hypoxia carried out in a pressure chamber prolonged twofold the latent period of seizure

OBJECTIVE One of the potential consequences of perinatal hypoxia-ischemia (H-I) is the development of epilepsy, and synaptic reorganization in the hippocampus has been associated with epilepsy after an injury. We tested the hypothesis that perinatal H-I will induce spontaneous motor seizures,

Evidence suggest that overexpression of hypoxia-inducible factor-1α (HIF-1α) is linked to multidrug resistance of epilepsy. Here we explored whether aberrant expression of HIF-1α is regulated by miRNAs. Genome-wide microRNA expression profiling was performed on temporal cortex resected from mesial

The comparative effects of antiinflammatory cytokine interleukin-10 on the epileptiform activity development in CA1 hippocampal neurons were studied in different functional models of epileptogenesis that are not accompanied the visible morphological disturbances in the brain cells: --in vitro

The development of acquired epilepsy after a perinatal hypoxic-ischemic (HI) insult was investigated in rats. After unilateral carotid ligation with hypoxia on postnatal day 7, cortical electroencephalographic and behavioral seizures were recorded with continuous radio-telemetry and video. Chronic

Although glycogen is the only carbohydrate reserve of the brain, its overall contribution to brain functions remains unclear. It has been proposed that glycogen participates in the preservation of such functions during hypoxia. Several reports also describe a relationship between brain glycogen and

The comparative effects of the anti-inflammatory cytokine interleukin-10 on the development of epileptiform activity were studied in hippocampal field CA1 neurons in different models of epileptogenesis not accompanied by visible morphological lesions in brain cells: 1) a model of hypoxic kindling in

To explore the involvement of hypoxia-inducible factor-1 alpha (HIF-1α) in the upregulation of P-glycoprotein (P-gp) in refractory epilepsy. Brain tissue specimens were collected and analyzed for expression of HIF-1α and P-gp using an immunohistochemical (IHC) staining method in both refractory

Moderate cerebral hypothermia is consistently neuroprotective after experimental hypoxia-ischemia; however, its mechanisms remain poorly defined. Using a model of complete umbilical cord occlusion for 25 min in 0.7 gestation fetal sheep, we examined the effects of cerebral hypothermia (fetal
