MORPHOLOGICAL AND BIOCHEMICAL CHANGES IN THE GASTRIC MUCOSA OF A/HEJ MICE INJECTED WITH A XENOGENEIC STOMACH ANTIGEN

Abstract
S.c. injection of W/Fu rat stomach antigen emulsified with an equal volume of Freund''s complete adjuvant at 1 wk interval for a total of 2 administrations induced atrophic gastritis in A/HeJ mice. From the 2nd wk after the last injection the parietal cell mass decreased. At the same time, Alcian blue-PAS [periodic acid-Schiff] positive cells and Paneth-like cells appeared. The activity of alkaline phosphatase and disaccharidase of the small intestinal mucosa was biochemically demonstrated in the atrophic glandular stomach.
