halothane elimination high hydrostatic pressure central neurons
2009/7/17
Autoactive neurons in the central nervous system of Helix and Aplysia were studied after exposure to several volatile anesthetics and under compression by mineral oil. Voltage clamp studies reveal tha...
Combined influence of temperature and hydrostatic pressure on cardiac conduction
cardiac temperature hydrostatic animal dog rabbit
2009/7/17
Interactions of temperature and hydrostatic pressure were examined in three types of cardiac tissue. Decreases in temperature from 37 degrees C to 27 degrees C and increases in pressure from 1 to 150 ...
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...
Hyperbaric chamber for evaluating hydrostatic pressure effects on tissues and cells
human chamber pressure effects tissues
2009/7/16
A chamber system is described for the study of pure hydrostatic pressure effects on tissues and cells. The small chamber has an internal volume of 7.6 liters and is rated for working pressures up to 4...
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...

The short-circuit current (Isc) was measured as an index of active net sodium transport across the isolated toad skin under various hydrostatic pressures up to 300 ATA. Upon compression, the base-line...
Effects of halothane and hydrostatic pressure on sodium channels in squid axon
neurological squid animal halothane high pressure nervous syndrome
2009/7/14
