Nitric oxide and superoxide mediate diesel particle effects in cytokine-treated mice and murine lung epithelial cells — implications for susceptibility to traffic-related air pollution

Table 1 Cellular glutathione 24 h after saline- or cytokine-treated LA-4 cells, with and without DEP

Cell Groups *n =* 3/group	GSH	GSSG	GSH:GSSG ratios
Saline	148 ± 2.9	35.7 ± 4.1	4.1 ± 0.4
Cytomix	164 ± 12.0	44.2 ± 3.2	3.7 ± 0.4
DEP	193 ± 28.9	40.3 ± 3.8	4.8 ± 0.3
Cytomix + DEP	394 ± 20.1*	132 ± 2.7*	3.0 ± 0.2

Data are expressed as mean pmol/μg protein (± SEM). Asterisk (*) indicates significantly different than saline-exposed cells ( p < 0.05).
