Figure 7From: Impact of agglomeration state of nano- and submicron sized gold particles on pulmonary inflammationAcute phase protein in serum 3 and 24 hours after instillation. A) Fibrinogen levels are significantly increased after 250 nm single and 50 nm agglomerated particles. B) CRP levels are significantly increased 3 hours after gold and quartz treatment. * P < 0.05 compared to negative control (n = 6 for gold and n = 3 for quartz).Back to article page
