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...
Voice fundamental frequency levels of divers in helium-oxygen speaking environments
human heliox speaking Voice speech intelligibility
2009/7/20
Divers under hyperbaric conditions experience a marked deterioration in speech intelligibility. Included among the possible features that contribute to speech degradation is change/distrotion of speak...
Effects of hyperbaric helium-oxygen on the antipyretic actions of aspirin and acetaminophen in rats
hyperbaric animal rat drug antipyretic aspirin acetaminophen heliox
2009/7/20
The effects of two antipyretics, aspirin and acetaminophen, were studied under hyperbaric helium-oxygen conditions. Groups of yeast-fevered rats were given three different doses of each antipyretic in...
