Abstract: In this study, histochemical features revealed a negative reaction for PAS-AB in epithelium and lamina muscularis of non-glandular part but showed a positive reaction for PAS. In the cardiac region, there was mild to moderate PAS reaction in the lining epithelium of the apical surface, glands, and lamina propria. With PAS-AB, the apical and middle portion of cardiac glands showed a positive reaction in 6^th day piglet, while in 21^st day piglets reaction was in the upper half. In fundic region in G-I, PAS reaction occurred on the surface epithelial cells, gastric pits, and base of the fundic gland. The intensity of the PAS reaction was higher in the lower third of the fundic glands in G-II and III. With PAS-AB intensity of the reaction was higher in epithelial cells and the upper half of the gland in groups II and III. In the pyloric region, all surface cells in mucosa, glands, and pits showed a positive reaction to PAS and PAS-AB with higher intensity in G-III than in the other two groups.
