摘要：

Diamine oxidase (DAO) is an enzyme, with high activity found in the small bowel mucosa of the rat and man, and with only very low activity in all other tissues. The enzymatic distribution along 8 consecutive small bowel segments of mucosa was investigated, and the DAO concentration on brush border membranes, obtained from whole mucosal homogenate in Wistar rats, was tested. DAO activity is mainly distributed in intermediate and distal small bowel segments, and is not significantly associated with enterocyte brush border.
