Synergistic damage from H2O2 and OH radicals in irradiated cells
Radiation Research
|April 1, 1983
Abstract:
The anoxic sensitization of bacterial spores by added H2O2 has been studied. Two mechanistic pathways for damage from H2O2 were found; one of these requires the presence of OH radicals. For this kind of damage, the relationship between H2O2 and OH appears to be that they are reactants. O-2 (and/or HO2), the product of such a reaction, is likely the agent which actually causes damage. These results with reagent H2O2 are compared with results of experiments in which H2O2 and OH are present as radiolytic products.
