Paraffin histological sections were stained to detect argirophilic apud cells – by Grimelius, argentaffin ones – by Masson-Hamperl. <...> The endocrine apparatus of the gut is represented by apud cells located among enterocytes of the mucous membrane. <...> The endocrine cells in the duodenum are only localized in the lower third of the crypt, in jejunum and ileum – along all their depth, in the caecum and rectum – also in the epithelium of the villus. <...> The amount of argirophilic and argentaffin endocrine cells constantly increases in the direction from the duodenum to rectum with the maximum amount in the middle part of the ileum. <...> The relative content of the visible argentaffin cells among the whole population of endocrine cells was the largest in the proximal third of the jejunum and in the middle third of the rectum 81,93 and 82,99 %, respectively and the least amount was in the initial compartment of the duodenum – 40,89 % as well as in the ileum and caecum 40,24 – 52,00 %. <...> Maximum and minimal values of the content of the apud cells do not always correspond to the anatomical borders of the intestine. <...> Дисперсная эндокринная система и концепция APUD / И.
