Levels of N2-ethylidene-dGuo (as N2-ethyl-dGuo) were measured in granulocyte DNA from each subject. The last row reports participants’ adduct levels measured 1 week before the first dose was given. This is the point at which participants began to abstain from consumption of any alcoholic beverage other than the dose given for the study. ‘Baseline’ levels of N2-ethyl-dGuo were also measured 1 h before each dose was given. The rows that follow report the levels of N2-ethyl-dGuo at the various time points after consumption of the three increasing doses (from dose 1 to dose 3).
Levels of N2-ethyl-dGuo not quantified due to poor recovery.
