The effects of H2O2-induced oxidative DNA damage in 80 healthy individuals
with relation to age (20-25 and 55-60 years old) and smoking has been
investigated with the comet assay technique. Both factors have shown a
significant effect upon basal DNA damage with smoking appearing to have the
most impact. A differentiation of the four groups response to induced
oxidative damage was also observed. A distinctly separate behavior of the
younger non-smokers group, when compared with the rest of the categories,
was found. This is attributed to the lower degree of initial basal damage
that occurs in their lymphocytes.
