Functional responses of diaphragm muscle in the rat to varying PCO2 levels and helium content in hyperbaric atmospheres
diaphragm carbon dioxide helium hyperbaric animal rat
2009/7/20
Functional responses of diaphragm muscle in the rat to varying PCO2 levels and helium content in hyperbaric atmospheres.
Supportive evidence for altered platelet function in the dived rat
decompression animal rat platelet
2009/7/20
A study was conducted on the changes in platelet function and platelet count in the Sprague-Dawley rat induced by a bends-producing N2-O2 compression-decompression cycle. In those instances where mild...
Changes in rat respiratory behavior under varying PCO2 levels and argon content in hyperbaric Ar-O2-CO2 atmospheres
respiratory carbon dioxide argon animal rat
2009/7/20
An anesthetized rat preparation has been used for breathing studies in hyperbaric Ar-O2-CO2 atmospheres in which total saturation pressure was varied in the range 1-19.1 ATA and PCO2 was set at levels...
Effect of compression rate on HPNS convulsion threshold in the euthermic rat
high pressure nervous syndrome compression rate animal rat
2009/7/20
The modification of the development of the high pressure nervous syndrome (HPNS) has been demonstrated by varying the external environment (chamber temperature, compression rate) or the internal envir...
The kangaroo rat as a model for type I decompression sickness
decompression kangaroo rats goats
2009/7/20
This study involved 720 exposures of 70 kangaroo rats trapped in West Texas and showed that decompression-induced tail biting in this animal provides a good animal model for marginal limb bends in man...
Effect of high ambient pressure and oxygen tension on organ blood flow in the anesthetized rat
perfusion oxygen animal rat
2009/7/16
Cardiac output (CO) and blood flow to major organs were investigated in pentobarbital-anesthetized rats using 85Sr- and 141Ce-labeled microspheres (MS) (15 +/- 1 microns (SD)) injected into the left v...
Sprague-Dawley rats were exposed to air at 6 ATA. The decompression time was varied from 30 s to 6 h, resulting in a total pressure time interval from 0--24 h. The amount of rat femoral cartilage prot...
Spontaneous activity of rat portal vein at normal and elevated hydrostatic pressure
portal vein hyperbaric animal rat
2009/7/16
The effects of high hydrostatic pressure on the spontaneous contractile activity of isolated rat portal veins were studied. During compression, an increase of activity was seen, whereas stable elevate...
Ruthenium red staining of blood-bubble interface in acute decompression sickness in rat
decompression sickness blood bubble interface animal rat
2009/7/16
The ultrastructure of the blood-bubble interface has been studied in rats decompressed experimentally. Subsequent to staining with ruthenium red there was detected by electron microscopy a continuous ...
Muscle preparations from rat atria were hydraulically compressed in circulating Tris-buffered solution kept at 37 degrees C. Spontaneously beating preparations decreased their beating frequency with 3...
Effects of hyperbaric oxygen on heart,brain,and lung functions in rat
hyperbaric rat heart brain lung oxygen pressures
2009/7/16
Electrocardiogram (ECG), electrocorticogram (ECoG), and respiratory rate (RR) were monitored in awake, unrestrained rats during continuous exposure to 1, 3, and 5 ATA O2 until death. The RR showed a c...
Pharmacokinetics of antipyrine, paracetamol, and morphine in rat at 71 ATA
Pharmacokinetic antipyrine paracetamol morphine animal rat
2009/7/16
The pharmacokinetics of [14C]antipyrine, [3H]paracetamol, and [3H]morphine were studied in male Wistar rats at 1 ATA and then at 71 ATA, each animal being its own control. Separate control groups were...
Decrease of ether induction time after exposure to dysbaric conditions in rat
decompression ether anesthesia animal rat
2009/7/16
