Oxidative stress markers
| Parameter | Control | PA | P valued |
|---|---|---|---|
| GSH/GSSGa | 10.1 ± 2.8 | 7.9 ± 2.1 | NS |
| 8OHdG/dGb | 9.5 ± 1.1 | 7.4 ± 0.7 | NS |
| TBARSc | 1.25 ± 0.08 | 1.14 ± 0.09 | NS |
a
Data are presented as a ratio of GSH to GSSG in the ELF.
b
Data are presented as the number of 8OHdG per 105 2dG in lung DNA.
c
Data are presented as malondialdehyde equivalences (nanomole per milligram of lung protein).
d
P values were determined using an unpaired t test with Welch's correction for unequal variances. NS, the P value was greater than 0.05.
