  • Title: Simultaneous measurement of in vitro gastroduodenal prostaglandin E2 synthesis and degradation in peptic ulcer disease.
    Author: Crampton JR, Gibbons LC, Rees WD.
    Journal: Scand J Gastroenterol; 1987 May; 22(4):425-30. PubMed ID: 3474773.
    Abstract:
    The ability of mucosal specimens from the stomach and duodenum to synthesize and degrade prostaglandin E2 has been determined in normal subjects and peptic ulcer patients. Significant reduction in fundic PGE2 synthesis capacity was observed in gastric ulcer patients. There was also significant reduction in the PGE2 degradation capacity of antral, fundic, and duodenal mucosal specimens in gastric ulcer patients. Patients with gastritis showed significant elevation of both antral and fundic PGE2 synthesis capacity compared with normal but no alteration in PGE2 degradation. No differences were observed in PGE2 synthesis and degradation rates in patients with duodenal ulcer. The results argue in favour of an association between impairment of PGE2 metabolism in the mucosa of patients with gastric but not duodenal ulceration.
