Histochemical analysis of reticular (A-D) and elastic fibers (E-H) in the rat stomachs. A and B) Groups I and II presented reticular fibers rectilinear and aligned (arrows) surrounding the epithelium (ep) and the stroma (s). C and D) Reticular fibers (arrow) winding and apparently densest at the base (arrowheads) of glands (g). Collagen fibers accumulation between the glands (*) were observed. E and F) The glands are accompanied by a delicate web of elastic fibers (arrow) and more intensely marked in E. G and H) An increase in the thickness of these fibers, disruption and fragmentation of fibrillar variables grouped masses of elastin (arrows) can be observed around the glands (g) compared to their respective control groups (I and II). Gomori's silver (A-D); Weigert's Resorcin-Fuchsin (E-H). Bars: 10 μm.
