ObjectiveAcute mesenteric ischemia (AMI) is an important clinical condition with a high mortality rate in abdominal emergencies due to delay in diagnosis in spite of the new strategies in the management. We have studied the role of diamine oxidase (DAO) in the early diagnosis of AMI.MethodsIn the study, 21 New Zeland rabbits were used. Subjects were named as the groups of controls, sham, and ischemia. No intervention was performed in the subjects in the control group. In the subjects from sham and ischemia groups, laparotomy was performed with middle line incision. However, superior mesenteric artery was found and tied in those from ischemia group after the performance of laparotomy. From the animals in 3 groups, blood was drawn at the hours of 0, 1, 3, and 6, and DAO and amylase were studied in these samples.ResultsThe increase in serum amylase levels was found to be statistically significant in the ischemia group compared with the control and the sham groups (P < .05). The decrease in serum DAO levels was found to be statistically significant in the ischemia group compared with the control and the sham groups (P < .05). Diamine oxidase levels were found to decrease, beginning from the 1 hour after ischemia had been developed, and this rise was found to continue for 6 hours (P < .05).ConclusionSerum DAO levels were decreased in ischemia. Further clinical and experimental investigations would be valuable to confirm the probable role of DAO in AMI.Copyright © 2013 Elsevier Inc. All rights reserved.
