Figure 3: Gömöri's reticulin, picrossirius, and resorcin-fucsin techniques for identification of reticular fibers (collagen III), general collagen, and elastic fibers. (a-n) show morphological aspects of the C (a, g, k), C + T (b, h, l), TG (c, d, I, m), and TG + T (e, f, j, n) prostates. (a and b) The regular localization of reticular fibers adjacent to the prostatic epithelium in the C and C + T groups. (c and e) On the other hand, the groups TG and TG + T showed some areas with reshuffling of these fibers, mainly in regions affected by lesions. (d and f) Inserts show the disposing of collagen III in unaffected TG and TG + T prostates. (i and j) Regarding general collagen, the prostates of TG and TG + T presented a high reshuffling of these fibers, specifically in injured regions. (m and n) Regarding the elastic system, we observed several regions with a changed pattern of these stromal components in both TG and TG + T. (n) Regions affected by adenomatous hyperplasia showed a reduced quantity of elastic fibers. ep: epithelium; l: lumen; s: stroma; arrows: reticular fibers; short arrows: general collagen; large arrows: elastic fibers.
