Brain lipid changes following hypoxia.
Brain Lipid Changes Following Hypoxia • Biochemical changes signaling irreversible damage in brain cells following hypoxia are incompletely understood. Disruption of membrane structure may play a role in this process. Lipids and long-chain fatty acids are important constituents of neural membranes and could serve as markers of membrane breakdown. The present study was undertaken to assess the b...
متن کاملNeuronal Cell Reconstruction with Umbilical Cord Blood Cells in the Brain Hypoxia-Ischemia
Background: Brain hypoxia-ischemia is a human neonatal injury that is considered a candidate for stem cell therapy. Methods: The possible therapeutic potential of human umbilical cord blood (HUCB) stem cells was evaluated in 14-day-old rats subjected to the right common carotid occlusion, a model of neonatal brain hypoxia-ischemia. Seven days after hypoxia-ischemia, rats received either saline ...
متن کاملEffects of brain hypoxia on ventilation.
For over a century it has been known that a lack of oxygen in the blood stimulates breathing. In 1868 PFLUEGER [69] postulated that hypoxia directly stimulat:s t~e respiratory centres in the medulla oblongata. Thi.s vtew was not challenged until the discovery of the penpheral cbemoreceptors, first of the aortic and later of the carotid bodies, by J.F. Heymans, C. Heymans and co-workers in the y...
متن کاملIncreased brain capillaries in chronic hypoxia.
The effect of chronic hypobaric hypoxia (28 days, 455 Torr) on the organization of brain vessels was studied in Balb/c mice. In comparison to age-matched controls kept at sea level, emulsion-perfused capillaries in hypoxic mice showed marked dilation in all brain areas studied. Capillary length per unit volume of tissue (Lv) was increased in the cerebellar granular layer, the caudate nucleus, t...
متن کاملEarly brain swelling in acute hypoxia.
Acute mountain sickness (AMS) and high-altitude cerebral edema share common clinical characteristics, suggesting cerebral swelling may be an important factor in the pathophysiology of AMS. Hypoxia and hypocapnia associated with high altitude are known to exert strong effects on the control of the cerebral circulation, yet how these effects interact during acute hypoxia, and whether AMS-suscepti...
