[Changes in the content of rat brain polyphosphoinositides after exposure to high partial pressures of helium and...

Effect of the medium with high partial pressure of helium and nitrogen on the content of di- and triphosphinositides in the rat brain great hemispheres. The stay of the rats in helium-oxygen mixture under the pressure of 40 kg/cm2 for 1 h is accompanied by the true decrease in the content of the both components of polyphosphoinositides whose value does not depend on the decompression conditions. Nitrogen-oxygen mixture under the pressure of 15 and 25 kgf/cm2 also evokes a decrease of the content of di- and triphosphoinositides. The character of reduction of the content of the both components for 4 h after the stay of the rats under the pressure of 25 kgf/cm2 depends on the decompression conditions.
