4-Hydroxyhexenal- and 4-Hydroxynonenal-Modified Proteins in Pterygia

Figure 1

Expressions of aldehyde-modified proteins in pterygia. Representative images of H&E staining (a, e, i, m, q, and u), 4-HHE (b, f, j, n, r, and v) and 4-HNE (c, g, k, o, s, and w) immunohistochemistry, and negative control staining (d, h, l, p, t, and x) are shown. Three specimens from the pterygial head (head 1, 2, and 3) and two specimens from the pterygial body (body 1 and 2) are shown at higher magnifications. H&E: hematoxylin and eosin; 4-HHE: 4-hydroxyhexenal; 4-HNE: 4-hydroxynonenal.
