Age-related susceptibility to oxygen and glucose deprivation damage in rat hippocampal slices.
Aging is an important risk factor for stroke. We evaluated the effects of aging on cell susceptibility to oxygen and glucose deprivation (OGD) in slices of the hippocampus from Wistar rats aged 2, 11 and 24 months. Lactate dehydrogenase (LDH) released to the incubation media and free radical content were markedly increased in the 24-month group submitted to OGD. These results confirm that hippo...
متن کاملProtective effect of mild hypothermia on oxygen-glucose deprivation injury in rat hippocampal neurons after hypoxia.
The present study aimed to establish an oxygen‑glucose deprivation (OGD) model of ischemic and hypoxic cerebral neurons to investigate the protective effect of mild hypothermia on neuronal OGD and its mechanisms. OGD injury was significantly mitigated in cells with 24 h of mild hypothermia compared with cells without mild hypothermia; cell morphology improved, the lactic acid dehydrogenase (LDH...
متن کاملEffects of the noradrenergic system in rat white matter exposed to oxygen-glucose deprivation in vitro.
Norepinephrine (NE) is released in excess into the extracellular space during oxygen-glucose deprivation (OGD) in brain, increasing neuronal metabolism and aggravating glutamate excitoxicity. We used isolated rat optic nerve and spinal cord dorsal columns to determine whether the noradrenergic system influences axonal damage in white matter. Tissue was studied electrophysiologically by recordin...
متن کاملprotective effects of berberine on oxygen-glucose deprivation/reperfusion on oligodendrocyte cell line (oln-93)
background: oligodendrocytes, the myelinating glial cells of central nervous system, are highly vulnerable to ischemic‑induced excitotoxic insult, a phenomenon in which calcium overload triggers cell death. berberine is an alkaloid extracted from medicinal herbs as coptidis rhizoma with several pharmacological effects like inhibition of neuronal apoptosis in cerebral ischemia. methods: we exami...
متن کاملSuperoxide (*O2- ) production in CA1 neurons of rat hippocampal slices exposed to graded levels of oxygen.
Neuronal signaling, plasticity, and pathologies in CA1 hippocampal neurons are all intimately related to the redox environment and, thus tissue oxygenation. This study tests the hypothesis that hyperoxic superfusate (95% O(2)) causes a time-dependent increase in superoxide anion (*O(2)(-)) production in CA1 neurons in slices, which will decrease as oxygen concentration is decreased. Hippocampal...
