Indicators of antioxidant status and oxidative stress in postnatal rat lungs following exposure to CGUFP. Changes in total glutathione (A) and GSH:GSSG ratios (B) in whole lung homogenates and 8-Isoprostanes in BALF (C) and whole lung homogenates (D) after CGUFP exposure. All measurements were made 24 hr post-exposure. n = 4-6 animals/group. Data are means ± SEM. *p < 0.05.
