Fig. 7From: Toxic and adjuvant effects of silica nanoparticles on ovalbumin-induced allergic airway inflammation in miceSNPs/OVA group induced airway inflammation compared to control. Hematoxylin and eosin stain (H&E stain) and Periodic acid Schiff (PAS) stain was done on lung sections from mice exposed to SNPs/OVA. 30 μl saline (a, f), 20 μg saline/OVA (b, g), 200 μg S-SNPs/OVA (c, h), 200 μg M-SNPs/OVA (d, i), 200 μg P-SNPs/OVA (e, j). Quantitation of inflammation cells was measured by Metamorph systemBack to article page
