Effect of pressure on the release of endogenous dopamine from rat striatum and the role of sodium-calcium exchange
model animal rat High Pressure Neurological Syndrome
2009/7/8
Exposure to environmental pressures in excess of 20 atm abs can precipitate a hyperexcitability state known as high pressure neurologic syndrome (HPNS). Little is known about the underlying neurochemi...
Effect of hyperbaric and normobaric oxygen on pulmonary endothelial cell function
pulmonary animal rat
2009/6/12
The effect of prior exposure to raised partial pressures of oxygen on pulmonary endothelial cell function was assessed in the isolated perfused rat lung preparation. Prolonged exposure to both 1 bar (...
Effect of severity, time to recompression with oxygen, and re-treatment on outcome in forty-nine cases of spinal cord decompression sickness

Our purpose was to examine the behavior of air bubbles in three non-lipid tissues (skeletal muscle, tendon, and the anterior chamber of the eye) during breathing of air, helium-oxygen (heliox, 80:20),...
Protective effect of oxygen and heliox breathing during development of spinal decompression sickness
decompression sickness helium heliox oxygen spinal cord animal rat air
2009/6/12
A rat model of spinal decompression sickness (DCS) allows study of spinal cord function for at least 3 h after decompression to 1 atm abs (101 kPa) after an exposure to air at 3.8 atm abs (385 kPa) fo...
Effect of beta 1-adrenoceptor blockade in rats at 5 bar ambient pressure
cardiac output air rat animal cardiac contractility Atenolol

Conscious rats exposed to 5 bar (500 kPa) ambient pressure show increased total myocardial blood flow (TMBF) and enhanced cardiac contractility in spite of unaltered mean arterial pressure (MAP), hear...
Effect of radical scavengers and hyperbaric oxygen on smoke-induced pulmonary edema
HBO pulmonary hyperbaric smoke radical scavenger animal rabbit
