Except for the control group, all groups were exposed to PM_(2.5) suspension intratracheally(equivalent to 7.5 mg/kg), poisoning 3 times a week, with an interval of 24 hours between each test. The vitamin E intervention group dissolved the salad oil with vitamin E by daily gavage, while the control group received an equal amounts of physiological saline. From the first day of exposure, lycopene was given daily via gavage for 4 weeks. Lycopene groups received lycopene dissolved in salad oil, while control and model groups received salad oil of the same volume. After 4 weeks, all rats were killed. Lung pathology sections were made and serum and lung tissue were collected and homogenized, centrifuge and collect the supernatant. Using UV visible spectrophotometry to measure levels of glutathione peroxidase(GSH-Px), glutataione(GSH), superoxide dismutase(SOD), total antioxidant capacity(T-AOC), malondialdehyde(MDA), glutathione S-transferase(GST), catalase(CAT), hydroxyl radical(OH), nitric oxide(NO). Using enzyme-linked immunosorbent Assays(ELISA) to measure levels of tumor necrosis facto-α(TNF-α), interleukin-6(IL-6), and 8-hydroxy-2-deoxyguanosine(8-OHdG). Lung histopathology was also observed.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Compared to the normal control group, there were significant differences in the content of GSH((9.47±1.37)mg/g vs. (11.10±3.82)mg/g), SOD((9.43±2.41)U/mg vs. (13.82±4.64)U/mg), CAT((5.35±1.88)U/mg vs. (9.54±3.06)U/mg), 8-OHdG((5.52±1.66)μg/g vs. (4.76±1.01)μg/g) in the serum, and GSH((2.19±0.29)mg/g vs. (3.18±0.49)mg/g), SOD((23.98±4.20)U/mg vs. (31.95±5.08)U/mg), CAT((5.85±1.95)U/mg vs. (3.57±1.96)U/mg), GSH-Px((49.15±7.01)mg/g vs. (68.46±11.15)mg/g), OH·((74.02±12.84)U/mg vs. (51.03±14.85)U/mg), TNF-α((5.57±0.72)ng/g vs. (7.83±1.60)ng/g), IL-6((2.68±0.39)μg/g vs. (3.82±1.35)μg/g) in lung tissue homogenates of PM_(2.5) group(P&lt;0.05).
