Measures of oxidative damage in the lungs of the rats at time of euthanasia at 36 weeks after irradiation. Panel A: Analysis of 8-OHdG staining as percentage positivity (the ratio of positive pixels/total number of positive and negative pixels in the tissue section with air spaces excluded); Panel B: Analysis of MDA levels (μM) in the lung tissue. Each bar represents the mean ± SEM for all rats available for analysis. Labeling of the treatment groups is as indicated in the legend to Fig. 2. Twelve-week controls animals were euthanized at the start of the experiment; 36-week controls were euthanized at 36 weeks postirradiation. The asterisks indicate groups that are significantly different from the whole-lung irradiation groups in each panel.
