Differences in epithelial enzyme activity in the duodenum, jejunum, and ileum of the monkey

  • Published:
The American Journal of Digestive Diseases Aims and scope Submit manuscript

Summary

Proximal duodenum, midjejunum, and distal ileum specimens were studied from 13 monkeys for nonspecific esterase, alkaline and acid phosphatases, leucine aminopeptidase, and reduced NAD and NADP dehydrogenases. In all animals and with all reactions, the epithelial cell activity was noted in the midgut and, depending upon the enzyme, the least activity in either the proximal duodenum or distal ileum.
