Figure 3:

the expression of selected inflammatory cytokine genes in lungs of SHAM, DEMED, and ADREX rats after exposure to air or ozone as determined using qPCR. Values represent mean ± SE of relative fold change from each day SHAM-air control (n=3–4 animals for SHAM air or ozone, and n= 5–6 for other groups). Comparisons between air and ozone under each surgery condition and the comparisons between different surgeries under the same exposure condition are shown in graphs (* indicate p value ≤ 0.05 with respect to surgery or ozone exposure). A) tumor necrosis factor alpha (Tnfα), B) interleukin 6 (Il-6), C) interleukin 1 beta (Il-1β), D) interleukin 4 (Il-4), E) interferon gamma (Ifnγ), F) interleukin 5 (Il-5) and G) interleukin 13 (Il-13).
