What Researchers Did
Researchers investigated oxidative DNA damage (FPG-sensitive sites, 8-OHdG) and HPRT mutations in human lymphocytes after a single hyperbaric oxygen (HBO) treatment, also examining the influence of GST genotypes.
What They Found
Researchers observed a clear induction of FPG-sensitive sites in lymphocytes after hyperbaric oxygen (HBO) treatment. However, no increased levels of 8-OHdG or HPRT mutations were detected, and these DNA effects were unrelated to the subjects' GST genotypes.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada, nor does it involve Canadian researchers or specific Canadian health data.
Study Limitations
This study's findings are limited by its focus on a single hyperbaric oxygen treatment session and the lack of long-term follow-up for mutation development.
