Figure 1From: NF-kB overexpression and decreased immunoexpression of AR in the muscular layer is related to structural damages and apoptosis in cimetidine-treated rat vas deferensPhotomicrographs of vas deferens of animals from CG (A and C) and CMTG (B and D) stained by Masson's trichrome. In B (CMTG), note that the epithelium (EP) is intensely folded and surrounds a decreased lumen (asterisk) in comparison to CG (A); a reduction in the muscular layer (M) is also evident. Lamina propria (LP). In C, a high magnification of epithelium (EP) shows epithelial columnar cells with normal aspect (arrows). In D, pyknotic nuclei (arrows) and vacuolization (v) are observed in the epithelial cells. Bars: 340 μm (A, B); 33μm (C, D).Back to article page
