From: Lung glutathione adaptive responses to cigarette smoke exposure
GSH levels rebound during CS exposure recovery period. The normal recovery period between smoke exposures is overnight which is typically about 16 hours. Mice were exposed to CS for 5 h and allowed to recover between 0 and 16 hours. ELF (A) GSH levels rebounds within 2 hours after exposure and peaks at 8 hours while plasma (C) GSH levels peak at 4 hours after CS exposure. The liver (D) GSH levels also rebound back to control levels and the lung (B) GSH levels are unchanged. Data represented as mean ± SEM, with different letters representing statistically significant differences between groups, p < 0.05.
