Figure 2From: Diesel exhaust particulate induces pulmonary and systemic inflammation in rats without impairing endothelial function ex vivo or in vivo Instillation of diesel exhaust particles (DEP) causes systemic inflammation. Plasma cytokines (a) Interleukin-6 (IL-6) (b) Tumour necrosis factor alpha (TNFα) & (c) C-reactive protein (CRP) were detected by ELISA. Non-instilled (open columns), saline-instilled (solid column) or DEP-instilled (0.5 mg; hatched columns) animals 6 and 24 h after instillation. Results are expressed as mean ± SEM (n = 4-6). , *P < 0.05, **P < 0.01 DEP versus saline; two-way ANOVA followed by Bonferroni post-hoc test.Back to article page
