Hyperbaric oxygen improves healing in experimental rat colitis.
This study was designed to investigate therapeutic effects of hyperbaric oxygen on experimentally induced colitis in rats by assessing oxidative tissue damage, neutrophil accumulation and histological changes.
Six groups of animals were used. No procedures were done in the sham group. In the vehicle group, 50% ethanol-induced colitis, and in four other groups, 2,4,6-trinitrobenzene sulphonic acid-induced colonic inflammation was achieved. In acute and chronic colitis non-treatment groups, no other procedure was done. In acute and chronic colitis hyperbaric oxygen treatment groups, rats underwent hyperbaric oxygen treatment for two or fourteen days.
Hyperbaric oxygenation mitigates focal cerebral injury and reduces striatal dopamine release in a rat model of transient middle cerebral artery occlusion.
Abstract: The usefulness of the administration of hyperbaric oxygen (HBO) in the treatment of acute focal cerebral ischemia remains debatable. A significant association exists between focal cerebral injury and an excessive release of extracellular dopamine (DA). In...
Hyperbaric oxygen and surgery.
Abstract: Hyperbaric oxygen (HBO) therapy, that is the administration of 100% oxygen delivered under pressure, has a beneficial effect in several surgical conditions. Its use has been assessed and audited and its pharmacological effects demonstrated. It is appropriate...
Early hyperbaric oxygen therapy for retinal artery occlusion.
Abstract: To assess whether early hyperbaric oxygenation (HBO) treatment has a beneficial effect on visual results after retinal artery occlusion (RAO). A comparative retrospective study in which medical records of all HBO-treated RAO patients in our department were...

[Hemodynamic and respiratory changes in athletes during deep breath-hold diving].
Abstract: The study analysed the hemodynamic and respiratory aspects of deep breath-hold diving. One male (59-year-old) and one female (32-year-old) subject were enrolled. They were both champion deep breath-hold divers. The dives were performed in the wet compartment...
Down regulation of COX-2 is involved in hyperbaric oxygen treatment in a rat transient focal cerebral ischemia model.
Abstract: The effect of hyperbaric oxygen (HBO) on cyclooxygenase-2 (COX-2) expression after transient focal ischemia was evaluated. A rat middle cerebral artery occlusion/reperfusion (MCAO) model was produced using the intraluminal filament method. After 2 h of...
Multiple sclerosis, an autoimmune inflammatory disease: prospects for its integrative management.
Abstract: Multiple sclerosis (MS) is aptly named for the many scars it produces in the brain and spinal cord. A sometimes fatal, often debilitating disease, MS features autoimmune inflammatory attack against the myelin insulation of neurons. Thymus derived (T) cells...
Cerebral arterial gas embolism following diagnostic bronchoscopy: delayed treatment with hyperbaric oxygen.
Abstract: To describe a clinical scenario consistent with the diagnosis of cerebral arterial gas embolism (CAGE) acquired during an outpatient bronchoscopy. Our discussion explores the mechanisms and diagnosis of CAGE and the role of hyperbaric oxygen therapy. A...
