5. Fig. 4
Light micrograph, safranin O staining at 100× magnification; (A) treated and (B) untreated. (A) Shows hyalinization (arrow) of annular material, collagen denaturation, and stromal disorganization. (B) Shows no evidence of histologic damage; in fact, one can see the normal lamellar pattern of the annulus (arrow).
