Effect of propranolol on brain electrical activity during hyperbaric oxygenation in the rat
drug brain electrical activity propranolol oxygen toxicity animal rat
2009/7/14
The effect of 1, 2, and 5 mg/kg propranolol on the neuroelectrophysiological manifestations of CNS oxygen toxicity was studied in conscious rats. Cortical electrodes for electrocorticographic (ECoG) r...
Hyperbaric oxygenation decreases blood flows in normal and septic rats
HBO hyperbaric septic animal rat
2009/7/8
The purpose of the study reported here was to characterize the effects of acute exposure to 100% oxygen at a pressure of 202.6 kPa on hemodynamics and organ blood flow in antibiotic-controlled bacteri...
Skeletal muscle metabolic enzymes are altered by hyperbaric oxygenation treatments
HBO Skeletal muscle metabolic enzymes rabbit animal
2009/6/12
To test whether repeated HBO exposures would increase activity of skeletal muscle metabolic enzymes, 27 rabbits (3 groups) were exposed 90 min/day, 5 days/wk to either 100% O2 at 243 kPa (HBO), 100% O...
Hyperbaric oxygenation treatments and metabolic enzymes in the heart and diaphragm
hyperbaric treatments diaphragm enzymes
2009/6/12
We previously found that intermittent hyperbaric oxygen exposure increases metabolic enzyme activity in soleus muscle. Since the metabolic enzyme activities of the heart and diaphragm of healthy anima...
Influence of delayed hyperbaric oxygenation on recovery from mechanically induced damage
hyperbaric recovery Influence
2009/6/12
This study examined whether subjecting a crushed muscle to a delayed intermittent hyperbaric oxygenation protocol would facilitate healing, the marker for healing being a return toward 100% uncrushed ...
Non-comatose patients with acute carbon monoxide poisoning: hyperbaric or normobaric oxygenation?
carbon monoxide HBO hyperbaric cerebral blood flow normobaric
2009/6/12
Twenty-six non-comatose patients with acute carbon monoxide (CO) poisoning were randomized into two groups. Both groups were treated as soon as possible and for 2 h, the first group by 100% normobaric...
Retinopathy of prematurity (ROP) usually occurs after a prolonged exposure to normobaric hyperoxia in newborn mammals and infants. We hypothesized that experimental ROP also could develop after acute ...
Inhibition of nitric oxide synthase on brain oxygenation in anesthetized rats exposed to hyperbaric oxygenhernia
HBO oxygen toxicity nitric oxide drug hyperbaric nitric oxide synthase animal rat
2009/6/9
Nitric oxide (NO) production is involved in the development of oxygen toxicity of the central nervous system (CNS) since inhibition of nitric oxide synthase (NOS) significantly protects animals from h...
Effect of hyperbaric oxygenation on peripheral nerve regeneration in adult male rabbits
hyperbaric air rabbit animal
2009/6/9
Oxygen environments were used to study the regenerative effects of hyperbaric oxygen on crushed sciatic nerves in 30 adult male rabbits. Six different oxygen environments were used, and treatments wer...
Bone composition and metabolism after hyperbaric oxygenation in rats with 1-hydroxyethylidene-1,1-bisphosphonate-induced rickets
HBO hyperbaric Bone composition animal rat
2009/6/8
We examined bone composition and metabolism after hyperbaric oxygenation (HBO) in Wistar rats with 1-hydroxyethylidene-1, 1-bisphosphonate (HEBP)-induced rickets. Twenty rats at 4 wk of age were divid...
Effect of hyperbaric oxygenation on bone in HEBP-induced rachitic rats
HBO dry hyperbaric animal rat
2009/6/8
The effect of hyperbaric oxygenation (HBO) treatment on rachitic change was studied using 4-wk-old, 1-hydroxyethylidene-1, 1-bisphosphonic acid disodium (HEBP-EHDP)-induced rachitic rats. After treatm...
Cell proliferative modulation of MCG 101 sarcoma from mice exposed to hyperbaric oxygenation
hyperbaric animal mice lactate dehydrogenase
2009/6/8
Tumor cell kinetics were studied in C57 Bl/J mice with a transplantable sarcoma, MCG 101, exposed to hyperbaric oxygen (HBO2), 2.8 atm abs, 2 hours daily for 9 days or until spontaneous death. The iso...
Platelet aggregation and release function in hyperbaric oxygenation
hyperbaric Platelet aggregation Platelet
2009/6/8
The aim of the study was to investigate the acute and chronic effects of hyperoxygenation on platelet aggregation and adenosine triphosphate (ATP) release. To observe the acute effects of hyperbaric o...
