Abstract

DE OLIVEIRA, Larissa Renata et al. MORPHOLOGIC CONSIDERATIONS ABOUT THE WALL OF THE  GLANDULAR STOMACH OF YOUNG RABBITS (Oryctolagus cuniculus). Rev. chil. anat. [online]. 2001, vol.19, n.3, pp.253-258. ISSN 0716-9868.  http://dx.doi.org/10.4067/S0716-98682001000300004.

The morphology of the stomach may vary between species as a function of feeding habits, differences on the cellular composition of the mucosa of the stomach wall and the different functions it carries out. Morphofunctional variations of the stomach of several animals along phylogeny led us to investigate the morphology of the wall of the glandular stomach of rabbits. We used the stomachs of 32 young rabbits (Oryctolagus cuniculus) from the White New Zealand strain, coming from the Experimental Farm of Iguatemi, owned by the State University of Maringá, Brazil. The stomachs were collected and fixed in Bouin solution; sections of 7 and 12 µm were made from the greater to the lesser gastric curvatures, and subjected to histological routine, for staining with either Hematoxilin-Eosin, P.A.S. or Azan. Next the sections were analyzed under microscope and photographed. Differences in the stratigraphy of the gastric wall were observed when the sections from the greater gastric curvature of the glandular stomach of rabbits were compared with those from the lesser curvature. We verified that the wall of the glandular stomach of rabbits shows differences on the morphology of the mucosa, submucosa, muscle and serosa layers, so that the wall is not uniform around the stomach circumference
