Figure 1

Reactive oxygen species (ROS) production. (A) Representative histograms from flow cytometry analysis using dihydroethidium (DHE) and 2',7'-dichlorofluorescein (DCF) in umbilical cord mononuclear blood cells from non-smokers and smokers. The log fluorescence (X-axis) illustrates the intensity of fluorescence for the number of cells counted. (B) Bar graph showing a remarkable increase in the level of superoxide anions (by DHE) and hydrogen peroxide (by DCF) in the smokers group (n = 23). The values are presented as means ± SEM. *p < 0.05 vs. non-smokers group (n = 30).
