Figure 3.
Redox potential values (Eh) for the reduced and oxidized (GSH/GSSG) thiol pair in the bronchoalveolar lavage fluid (BALF). The Eh values of the BALF were calculated from the GSH and GSSG concentrations using the Nernst equation with an E0 value of [GSSG]/[GSH]2 = −264 mV at a pH of 7.4. Data are presented as box plots. bp < 0.004 when the nonsmoking control group was compared with the nonsmoking group that abused alcohol; cp < 0.001 when the smoking control group was compared with the smoking group that abused alcohol.
