ABSTRACT


The aim of the study was the histological investigation
of gastric wall in pig's stomch during the foetal period. This work was
carried out on 138 domestic pig foetuses, including 68 males and 70 females. Whole
investigated material came from Department of Anatomy and Histology collection
Agricultural University of Wroc│aw and it was genetic equal, known origin (including
the horn of uterus), sex and age.The histological slides from the cardiac, fundic
and pyloric region were stained with H – E and Masson – Goldner stain. The histometric
measurements were carried out and statistically analysied. All aquired results
were presented as tables, diagrams and figures. During the histological interpretation
NH were used. The development of stomach wall layers was described. The developmental
investigations proved, the simple columnar epithelium of gastric mucosa in the
whole investigated period of pregnancy. The muscular layer of mucosa, the first
parietal cells and the muscular layers division occurred in the 60th day
of gestation. The histometric measurements and its statistcal analysis was carried
out. It proved the positive allometric growth of gastric mucosa thickness after
the 60th day of gestation according to the rapid gastric glands development.
The significant decrease of the mean values of separate muscular layers and mucous
membrane thickness in the third group can be explained by the gastric glands
development, the submucosa separation and the muscular layer partition.

Key words: pig, stomach, mucosa, submucosa, muscular layer, glands, prenatal development.
