What Researchers Did
Researchers investigated DNA integrity by measuring DNA strand breaks in lymphocytes from 100 patients before and after hyperbaric oxygen therapy sessions.
What They Found
DNA strand breaks significantly increased after the first HBO session but returned to normal levels within two hours of in vitro incubation. Furthermore, these elevated breaks consistently decreased and reached baseline levels after the fifth session of HBO therapy.
Canadian Relevance
This study does not have a direct Canadian connection.
Study Limitations
A limitation is that the long-term biological significance of the observed transient DNA damage in lymphocytes remains unclear.
