Skeletal response of growing rats to continuous long-term hyperbaric helium-oxygen exposure
hyperbaric Skeletal animal rat heliox
2009/7/20
Bone growth and composition were studied in growing rats following continuous long-term hyperbaric exposure. Six groups of eight rats each were maintained at 21 ATA He-O2 (200 mm Hg O2) and six groups...
Blood-brain and blood-lung barrier alteration by dysbaric exposure
decompression blood-lung exposure
2009/7/20
Failure of certain circulating substances to penetrate specific organs led to the concept of blood-organ barriers. Such barriers can be altered by various physical or chemical means. This report conce...

heliox oxygen toxicity endocrine animal rat
2009/7/20
The effects of long-term hyperbaric exposure on endocrine organ weight and histology and on epiphyseal-plate width were studied in growing male rats. Six groups of rats were exposed to 21 ATA He-O2 (2...
Pulmonary alveolar macrophage response to hyperbaric carbon monoxide exposure
carbon monoxide pulmonary CO animal guinea pig HBO
2009/7/17
The sublethal effects of carbon monoxide (CO) in hyperbaric environments have not been adequately characterized. A physiologically sensitive indicator of sublethal effects of a contaminant is the pulm...

CO2 carbon dioxide exercise psychomotor test electrobiological
2009/7/17
Pulmonary function, acid-base balance, renal electrolyte excretion, hematology, biorhythms and psychomotor test results were studied in six men during 30 days of exposure to a PICO2 of 14 torr (FICO2 ...
Calcium, magnesium, and phosphorus metabolism, and parathyroid-calcitonin function during prolonged exposure to elevated CO2 concentrations on submarines
submarine CO2 carbon dioxide
2009/7/17
Studies of calcium and phosphorus metabolism and acid-base balance were carried out on three Fleet Ballistic Missile (FBM) submarines during prolonged exposure to elevated concentrations of CO2. The a...
Effect of prolonged exposure to 0.5% CO2 on kidney calcification and ultrastructure of lungs
air animal guinea pig
2009/7/17
Guinea pigs were exposed for up to 8 weeks to 0.5% CO2, 21% O2, and balance N2. Control groups of the same age were kept simultaneously in environmental chambers on air. A slight increase in PaCO2 and...
Effect of intermittent exposure to 3% CO2 on respiration,acid-base balance,and calcium-phosphorus metabolism
CO2 carbon dioxide hydrogen acclimatization air
2009/7/17
One subject was exposed for six days to increasing levels of CO2, rising at a constant rate from 0.03 to 3.0% CO2 within a 15-h period followed by 9 h of air breathing. To assess acid-base parameters,...
Human parotid alpha-amylase secretion as a function of chronic hyperbaric exposure
human alpha-amylase parotid gland
2009/7/17
Secretion of alpha-amylase by the human parotid gland increased significantly during eight days of hyperbaric exposure. This hyperactivity of the parotid gland presumably resulted from increased auton...
