High pressure neurological syndrome: antagonistic effects of helium pressure and inhalation anesthetics on the dopamine-sensitive cyclic AMP response
High pressure neurological syndrome animal rat
2009/7/17
The antagonistic effects of helium pressure and certain inhalation anesthetics on the dopamine-sensitive cAMP response in the caudate nucleus of rat brain were examined. Helium pressure suppressed bas...

Endogenous dopamine (DA) and 3,4-dihydroxyphenylacetic acid (DOPAC) were measured by high performance liquid chromatography with electrochemical detection in perfusate from continuously superfused rat...
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...
Effects of NMDA administration in the substantia nigra pars compacta on the striatal dopamine release before and after repetitive exposures to nitrogen narcosis in rats

2009/6/2
Hyperbaric nitrogen-oxygen exposure developed in rats a decrement of the striatal dopamine release, which was reversed by repetitive exposures. This dopamine decrease could be the result of the antago...
