    (W B Saunders Co-Elsevier Inc, 2013) Karabulut, Keziban Ucar; Narci, Huseyin; Gul, Mehmet; Dundar, Zerrin Defne; Cander, Basar; Girisgin, A. Sadik; Erdem, Sami
    Objective: Acute 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. Methods: In 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. Results: The 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). Conclusion: Serum DAO levels were decreased in ischemia. Further clinical and experimental investigations would be valuable to confirm the probable role of DAO in AMI. (c) 2013 Elsevier Inc.

    The role of neopterine in the diagnosis of patients with acute pancreatitis on admission to the emergency department
    (2016) Gül, Mehmet; Uçar Karabulut, Keziban; Uçar, Yıldız; Erdem, Sami
    Purpose: There are difficulties observed in the diagnosis of acute pancreatitis in emergency departments due to its different clinical properties and the insufficiencies in the methods of diagnosis. Since there is no specific biochemical indicator, the diagnosis is made usually late or with difficulty. Neopterine is an enzyme secreted from the macrophages and is an indicator of cellular immunity activation. The aim of this study was to determine the role of neopterine in the early diagnosis of acute pancreatitis. Material and Methods: 39 patients, who had been hospitalized with the complaints of abdominal pain and diagnosed as acute pancreatitis via laboratory and screening methods, and 30 healthy controls were included in the study. Amylase, lipase, cholesterol and neopterine were measured in the patients' samples. The diagnoses were confirmed with abdominal ultrasound and computed tomography. Results: The neopterine values in patients with acute pancreatitis were significantly higher than those of the control group. Conclusion: Neopterine is an indicator which is elevated in certain inflammatory and autoimmune situations. We believe that it is important in the early diagnosis of acute pancreatitis. Further experimental and clinical studies should be conducted on the subject.
