  • Abstract
  • Look Inside

 The changes in gastric mucosa of ICR/JCL mice following subcutaneous injections with the antigen prepared from homologous stomach in Freund's complete adjuvant were studied histophathologically. The changes in the reticuloendothelial system after injections with the antigen were similar to those seen at the time of production of antibodies. Concomitant with above changes, degeneration of cells with pyknosis occured, gastric mucous cell mass decreased and thereafter mild atrophy developed in the gastric mucosa. Four weeks after a total of 4 injections, there was regeneration of mucous cells, but atrophy of both chief and parietal cells in fundic gland mucosa continued. Morever, the level of atrophy confirmed by performing the cell counts, The control groups given adjuvant alone did not show atrophic changes in gastric mucosa. These observations were discussed on the basis of immunology.
