Abstract
Mucosal diamine oxidase (DAO) decreases during intestinal ischemia and may be a useful
marker of intestinal ischemic injury. Tissue DAO activity and histologic changes were
studied in intestinal segments taken from the midpoint of the small intestine before
and 2, 4, and 24 hr after manipulation of the intestinal blood supply in 24 mongrel
dogs. Intestinal DAO activity decreased significantly (17 ± 21% of control value)
24 hr after SMA ligation and was associated with abnormal histology (histology score
7.8 ± 2.9 at 24 hr vs 0.3 ± 0.5 at 0 hr). SMA occlusion for 2 hr resulted in a significant
decrease in DAO activity (45 ± 36% of control value) 4 hr after manipulation which
returned to normal at 24 hr, as did the histologic injury. Ligation of both the mesenteric
arteries and veins resulted in a more rapid decrease in DAO activity. Decreased DAO
activity correlated with the extent of histologic injury. Intestinal ischemia is associated
with decreased intestinal DAO activity, which is influenced by the mechanism and duration
of intestinal ischemia.
