What Researchers Did
Researchers studied how hyperbaric oxygen treatment affected DNA damage and the body's ability to protect against further damage in human blood cells.
What They Found
After a single hyperbaric oxygen treatment (100% oxygen at 2.5 ATA for three 20-minute periods), DNA damage was observed, but not after subsequent treatments. Blood samples taken 24 hours after the treatment showed protection against DNA damage from hydrogen peroxide, a protective effect that lasted for at least one week. This suggests an increase in the body's antioxidant defenses at a cellular level.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This study was conducted in 1998 and focused on cellular-level effects in healthy volunteers rather than clinical outcomes in patients with specific conditions.
