Decompression sickness in the goat:nature of brain and spinal cord lesions at 48 hours
decompression animal goat
2009/7/17
An investigation was undertaken to determine whether permanent damage to the central nervous system (CNS) is associated with transient decompression sickness in the goat. Twelve goats were compressed ...
Therapeutic effects of hyperbaric oxygen and dimethyl sulfoxide following spinal cord transections in rats
Gelderd,JB Welch,DW Fife,WP Bowers,DE
2009/7/17
Thirty adult, male, Long-Evans hooded rats underwent spinal cord transections at the T5 vertebral level. Following surgery, animals were separated into three groups: Group I received only normal posto...
Six experimental investigations of various mechanical aspects of the spinal cord are described relevant to its injury by gas deposited from solution by decompression. These show appreciable resistance...
Pressure in the treatment of spinal cord decompression sickness
decompression sickness spinal cord animal dog
2009/7/15
Previous work had shown that a Po2 of about 2.0 bar was the optimal Po2 for the treatment of spinal cord decompression sickness (DCS). With 20 anesthetized dogs the hypothesis was tested that pressure...
Oxygen in the treatment of spinal cord decompression sickness
decompression sickness spinal cord Oxygen spinal evoked potentials animal dog
2009/7/15
Twenty-five anesthetized dogs were used to find the optimum Po2 for the delayed treatment of spinal cord decompression sickness (DCS). They were instrumented for the measurement of physiological varia...
Light and electron microscopic alterations in spinal cord myelin sheaths after decompression sickness
decompression sickness spinal cord myelin sheath animal dog
2009/7/14
Pathological examination of spinal cords from animals subjected to experimental decompression sickness (DCS) was undertaken in an attempt to explain the disparate response to treatment observed. Eight...
Involvement of serotonin in the enhancement of the rat spinal excitability by high pressures
2009/7/10
Using an electrical stimulation of the reticulospinal tract at the level of the medial longitudinal fasciculus, the effects, and the neurochemical mechanisms of these effects, of a progressive increas...
Heliox treatment for spinal decompression sickness following air dives
spinal decompression sickness air Heliox
2009/7/10
Enforced delay in treatment of spinal decompression sickness following scuba diving can result in paraplegia. Poor response from initial recompression to 18 m presents the clinician with a difficult m...
Arterial gas embolism as a pathophysiologic mechanism for spinal cord decompression sickness
decompression Arterial gas embolism spinal cord animal dog
2009/7/9
A continuous infusion of air (1.0 ml.min-1) was delivered via a fine aortic cannula into the arterial circulation of 7 anesthetized dogs until no spinal cord function could be elicited by somatosensor...
Effect of He-O2,O2,and N2O-O2 breathing on injected bubbles in spinal white matter
oxygen heliox decompression animal rat nitrous oxide spinal white matter
2009/7/8
Injected air bubbles in spinal white matter in the rat were studied at 1 bar after decompression from an exposure to air at 3.1 bar (absolute) for 4 h. During air breathing all injected bubbles grew f...
High pressure effects on reflexes in isolated spinal cords of newborn rats
saturation spinal cord animal rat
2009/7/8
High pressure induces hyperexcitability and convulsions in both intact and decerebrated animals. However, pressure suppresses synaptic transmission in isolated invertebrate preparations. We examined t...
Effect of severity, time to recompression with oxygen, and re-treatment on outcome in forty-nine cases of spinal cord decompression sickness
decompression sickness outcomes recompression spinal cord treatment re-treatment case reports human
2009/6/12
For systematic study of the effects of clinical severity, time to recompression with oxygen, and re-treatment on outcome from spinal cord DCS, case records from the recompression chamber at the U.S. N...
Spinal decompression sickness:hydrophobic protein and lamellar bodies in spinal tissue
decompression animal sheep
2009/6/12
Four basic studies have addressed the question of why the spinal cord is so vulnerable to decompression injury, with symptoms exceeding those related to the brain by a ratio often quoted as 3:1. Hydro...
Oxy-helium treatment of severe spinal decompression sickness after air diving
spinal decompression sickness HBO air heliox
2009/6/12
Spinal cord injury in DCS after air diving is relatively frequent and often has late sequelae. U.S. Navy oxygen tables are sometimes not satisfactory. The advantage of using helium in these cases is b...
Release of surfactant and a myelin proteolipid apoprotein in spinal tissue by decompression
animal bovine
2009/6/12
Two experiments have been performed on sections of bovine spinal cord, the first demonstrating that surface-active phospholipid (SAPL) and myelin proteolipid protein (PLP) are released by bubbles prod...
