ozone preconditioning reduces a key enzyme linked to oxidative stress during tissue reperfusion
Ozone oxidative preconditioning significantly attenuated the conversion of xanthine dehydrogenase (XDH) to xanthine oxidase (XO) during hepatic ischemia-reperfusion, reducing total XO activity from 53% of total enzymatic activity (in I/R group) to 38%, thereby limiting superoxide radical generation.
What this means for you
When blood flow is restored to oxygen-starved tissue, a surge of damaging free radicals can follow. Ozone preconditioning appears to blunt this response by keeping a pro-oxidant enzyme — xanthine oxidase — from spiking. Less of that enzyme activity means less oxidative damage, which matters for recovery, resilience, and long-term cellular health.
