Abstract

SOL, Mariano del  and  VASQUEZ, Bélgica. MESOSCOPY AND HISTOLOGY OF THE VESICULAR GLAND IN THE RABBIT (Oryctolagus cuniculus). Int. J. Morphol. [online]. 2003, vol.21, n.4, pp.325-330. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022003000400011.

The objective of this study was to find out more details about the vesicular gland of the rabbit (Oryctolagus cuniculus) to later proceed with their morphofunctional studies. 12 male clinically healthy rabbits (Oryctolagus cuniculus) were used and kept in the Biotery of the Faculty of Medicine of the Universidad de la Frontera, Temuco, Chile. The rabbits were slaughtered and their body weight was recorded, the pelvic region was dissected, removing in block the anatomic components of the urogenital system, later isolating the vesicular gland from the nearly glands. The samples were fixed in buffered formalin and processed for their inclusion in paraplast. Serialized cuts of 4µ thick were performed, which were stained for their histological and histochemical studies. For morphological analysis and for the photographs a Carl Zeiss Axiolab with MC 80 DX microscope was used. The results showed that the male rabbit (Oryctolagus cuniculus) vesicular gland presented an irregular shape, cranially globed and caudally. The vesicular gland was variable size and volume according to the specimen and the dilation due to the presence of liquid in the inner side. The dorsal wall of the gland in its craneal part is related to the ending part of the colon and rectum. The caudal part is related to the proprostate and it forms the ejaculatory duct in its distal end. The ventral wall is connected with the ampulla of the deferent duct. The histochemical study shoed that the vesicular gland was made up of a muscular layer with muscular smooth fibers irregularly organized and a mucous layer with an own sheet rich in colagenous fibers and blood vessels on which the simple low to cubic column gland epithelium rests. Histochemistry revealed the presence of sulfate and non sulfate acid mucines mainly in the apex zone of the gland cells and towards the lumen of each gland. No presence of glucogen nor of neutral mucines was observed
