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

Figure 3

Expressions of aldehyde-modified proteins in conjunctiva from rats exposed to 330 nm wavelength light. The eyes were exposed (a–d, i–l, and q–s) or unexposed (e–h, m–p, and t–v) to the light. Representative images of H&E staining (a–h) 4-HHE (j–l, n–p) and 4-HNE (q–v) immunohistochemistry, and negative control staining (i, m) are shown. Three specimens from the conjunctiva (1, 2, and 3) are shown at high magnifications. Insertions are higher magnifications of squares (k, o, r, and u). H&E: hematoxylin and eosin; 4-HHE: 4-hydroxyhexenal; 4-HNE: 4-hydroxynonenal.
