What Researchers Did
Researchers conducted a prospective, double-blind, randomised, placebo-controlled study with 20 healthy volunteers to investigate if an oral superoxide dismutase (SOD)-wheat gliadin formulation could prevent hyperbaric oxygen (HBO)-induced oxidative cell stress.
What They Found
After hyperbaric oxygen exposure, participants who received the SOD-wheat gliadin formulation showed significantly lower DNA strand breaks (tail moment, p = 0.03) and reduced isoprostane levels (p = 0.049) compared to the placebo group. Blood glutathione peroxidase activity was also significantly lower in the SOD group after HBO exposure (p = 0.045).
Canadian Relevance
This study was not conducted in Canada and does not have a direct Canadian connection.
Study Limitations
A limitation of this study is its small sample size of 20 healthy volunteers, which may limit the generalizability of the findings.
