1. Effect of hyperbaric oxygenation on the expression of glutathione peroxidase 4 and lactoperoxidase genes in the lung of isogenic mice after ischemia/reperfusion injury in the small bowel
Abstract Purpose: To evaluate the effect of hyperbaric oxygenation (HBO) on the expression of the genes antioxidant glutathione peroxidase 4 (Gpx4) and lactoperoxidase (Lpo) in the lung of mice subjected to intestinal ischemia and reperfusion (IIR). Methods: Control group (CG) in which were subjected to anesthesia, laparotomy and observation for 120 minu

2. Hyperbaric oxygenation and the genic expression related to oxidative stress in the heart of mice during intestinal ischemia and reperfusion
Abstract Purpose: To investigate the effects of hyperbaric oxygenation (HBO) on intestinal ischemia and reperfusion (IR) injury, we evaluated the expression of 84 genes related to oxidative stress and the antioxidant response in mouse hearts. Methods: Four groups were subjected to 60 minutes of intestinal ischemia followed by 60 minutes of reperfusion: IR

3. Effect of hyperbaric oxygenation on mitochondrial function of neuronal cells in the cortex of neonatal rats after hypoxic-ischemic brain damage
The timing and mechanisms of protection by hyperbaric oxygenation (HBO) in hypoxic-ischemic brain damage (HIBD) have only been partially elucidated. We monitored the effect of HBO on the mitochondrial function of neuronal cells in the cerebral cortex of neonatal rats after HIBD. Neonatal Sprague-Dawley rats (total of 360 of both genders) were randomly divide

4. Action of hyperbaric oxygenation in the rat skin flap
PURPOSE:To evaluate the morphology, necrotic area and collagen content in skin flaps of rats subjected to hyperbaric oxygenation (HBO).METHODS:Forty adult rats were divided into four groups: GEC - epilated; GE/HBO - epilated subjected to HBO; GER - epilated submitted to skin flap (2 cm in width /8 cm length in the dorsal area) and GER/HBO - epilated, subject

5. Immunoexpression of proliferating cell nuclear antigen (PCNA) in spleen of splenectomized rats with preservation of inferior pole, submitted to hyperbaric oxygenation
PURPOSE: To analyze PCNA immunoexpression on the inferior pole of the spleen of splenectomized rats submitted to hyperbaric oxygenation (HBO). METHODS: Were analyzed fragments of the inferior pole of the spleen of 20 male Wistar rats submitted to splenectomy with preservation of the inferior pole. The rats were divided in two groups: group A (n=10) without H

6. Estudo da ação da oxigenação hiperbárica em Pseudomonas aeruginosa / Study of action of hyperbaric oxygenation in Pseudomonas aeruginosa
Pseudomonas aeruginosa é um dos principais patógenos oportunistas responsáveis pelas infecções nosocomiais. Essas infecções representam um grave problema de saúde para pessoas com feridas graves e queimaduras, sendo responsável por altas taxas de mortalidade nos pacientes. Os tecidos cronicamente lesados apresentam microáreas de hipóxia, pouco vas

7. Experimental study with GM1 ganglioside and hyperbaric oxygenation in spinal cord injury in rats / Estudo dos efeitos do monossialogangliosídio (GM1) e da câmara de oxigenoterapia hiperbárica na lesão medular aguda em ratos
The objectives were to evaluate the effect of GM1 ganglioside, hyperbaric oxygen, and both in combination, in the treatment of experimental spinal cord lesions in rats. Thirty-two Wistar rats with spinal cord lesions were divided into four groups: one group received GM1 ganglioside, one was submitted to hyperbaric oxygen therapy, the third received both trea

8. Structural alterations of rat carotid body exposed to hyperbaric oxygenation / Alterações estruturais de corpos carotídeos de ratos expostos à hiperoxigenação hiperbárica
We sough to confirm the existence of structural alterations in rat carotid bodies exposed to hyperoxia that could explain the attenuation of the ventilatory hypoxic drive (HD) by hyperoxic conditions described in the literature. We also tested the hypothesis of there being a deviation of blood flow toward intraglomic capillaries in situations of hyperbaric o

9. Efeitos do pré-condicionamento por oxigenoterapia hiperbárica na lesão de isquemia e reperfursão em ratos
Liver ischemia/reperfusion injury (IR injury) is a cellular and immunological insult. It occurs in various clinical situations in which blood flow to the liver is interrupted. Hyperbaric oxygenation (HO) has been used as a treatment option in several ischemic diseases. However the effectiveness of this method as protective against IR injuries is controversia

10. Effect of hyperbaric oxygenation on the regeneration of the liver after partial hepatectomy in rats
The aim of the present study was to assess the influence of hyperbaric oxygenation (HBO) on rat liver regeneration before and after partial hepatectomy. Rats were sacrificed 54 h after 15% hepatectomy, liver and body weights were measured, and serum alanine transaminase (ALT) and aspartate transaminase (AST) activity and albumin levels were determined. The l
