Cytogenetic effects of hyperbaric oxygenation

This paper presents cytogenetic data obtained from peripheral blood of patients who were treated with hyperbaric oxygenation (HBO) at 0.15-0.2 MPa for 40 min daily during 10 days. The patients showed a significant increase of chromosome aberrations mainly caused by chromatid and chromosome breaks. The level of induced aberrations showed individual variations. These results suggest that HBO may have an indirect effect on the genetic apparatus of human somatic cells.
