Figure 2: Photomicrographs of sinus mucosa on the 4th day. The mucosa was thin in the normal (a) and saline (b) control groups. In the LPS group (c), the mucosa was markedly thickened. The sTNFRI (d), antibiotic (e), and sTNFRI/antibiotic (f) groups showed significant decreases in mucosal thickening compared with the LPS group (c) (hematoxylin-eosin staining; scale bar = 1 mm).
