Figure 4: Detection of 8-oxo-dGuo levels in urine. Urine was measured for levels of 8 8-oxo-7,8-dihydro-2’-deoxyguanosine and normalized to creatinine level (ng/mg creatinine). Panel A shows a box plot 8-oxo-dGuo levels in both diet groups (control and flaxseed) at the four time points. Panel B shows the urinary 8-oxo-dGuo level trend in 6 patients (2 control, 4 flaxseed).
