HISTOCHEMICAL STUDIES ON MUCOSUBSTANCES IN THE PYLORIC STOMACH OF CHAMAELEON ZEYLANICUS LAURETI

<p>The histological architecture, localization and quality of mucosubstances in<br>the pyloric stomach of Chameleon zeylanicus laureti is described. Pyloric stomach is a<br>narrow tubular posterior part of stomach. The histological study revealed that the wall<br>of pyloric stomach is composed of mucosa, submucosa, muscularis and serosa. Mucosal<br>epithelium was single layered formed mainly of tall columnar cells and few goblet cells.<br>Histochemical study showed the presence of moderate amount of neutral<br>mucosubstances and poor quantities of sialomucins in the epithelial cells. Goblet cells<br>contained moderate amount of sulfomucins. Three types of glands have been identified in<br>pyloric stomach depending upon the type of mucosubstances secreted by the gland cells.<br>Glands-Type I indicated the presence of only neutral mucosubstances (intense). GlandsType II cells contained only sulfomucins (intense). In glands-Type III, two types of cells<br>were observed, the type I and the type II cells. Type I cells in these glands contained only<br>neutral mucosubstances (intense). Glands-type II cells contained only sulfomucins<br>(intense).</p> <p>
