abstract：:When mice were exposed to 100% oxygen at a pressure of 6 atm. absolute, the animals suffered from severe convulsions. The content of gamma-aminobutyric acid (GABA) in synaptosomes was lower in the exposed animals than in unexposed ones. The exposure to high pressure oxygen produced a considerable reduction in GABA for...
