title: [Cytogenetic after-effects of fractionated and prolonged exposure to hyperbaric oxygenation].
abstract: The effect of hyperbaric oxygenation was investigated in bone marrow cells of rats, at prolongated and fractionated regimes usually employed in medicine. As a result of this study, it was pointed out that fractionated treatment of animals at I ata I h during 5 and 10 days affects the rats cytogenetically and causes several chromosomal damages. Prolongated treatment with high pressure oxygen was of a less mutagenic activity. The data obtained suggest nondirect action of this mutagen on the genetic apparatus.
