Epithelial lining fluid (ELF) GSH levels with repeated CS exposures. Mice were exposed to CS for 5 days/week between 1 and 120 days. ELF GSH levels are highest after 1 day of CS compared to repeated exposures. Data represented as mean ± SEM, with different letters representing statistically significant differences between groups, p < 0.05.
