Carboxyhemoglobin Formation in Preterm Infants Is Related to the Subsequent Development of Bronchopulmonary Dysplasia

Figure 3

Urinary levels of 8-hydroxydeoxyguanosine (8-OHdG) during the early postnatal period correlated with the subsequent development of BPD, but urinary levels of advanced oxidative protein products (AOPP) and Nε-(hexanoyl) lysine (HEL) showed no such correlation. The urinary levels of (a) 8-OHdG, (b) AOPP, and (c) HEL were compared between the no-or-mild BPD (open bars) group and the moderate-to-severe BPD group (closed bars) on the postnatal days indicated. < 0.05 for the no-or-mild BPD group versus the moderate-to-severe BPD group on the postnatal days indicated.
