Duodenal mucosal architecture in non-specific and ulcer-associated duodenitis.
This study was done to determine the severity and extent of abnormalities of duodenal mucosal architecture in non-specific (non-ulcerative) and ulcer-associated duodenitis. The effect of successful treatment with cimetidine on these changes has also been assessed. A method of microdissection and measurement of villus height, crypt depth, and mitotic figure count per crypt was applied to endosco...
متن کاملMucosal cell proliferation in duodenal ulcer and duodenitis.
Mucosal cell proliferation in the first part of the duodenum was studied in 24 patients using a tissue culture technique in which endoscopic biopsies were subjected to autoradiography after exposure to tritiated thymidine. Eight patients had a normal duodenum, eight had duodenal ulcer, and eight had symptomatic chronic non-specific duodenitis. The mean crypt labelling index (LI) in normal duode...
متن کاملCytomegalovirus Associated Duodenal Ulcer and Duodenitis in a Malnourished Pediatric Patient
Cytomegalovirus (CMV) duodenitis is a rare occurrence, especially in pediatric patients. A thirteen-month-old female presented to the Emergency Department for a febrile seizure. She was incidentally admitted for severe malnutrition with an initial workup remarkable for only a slight elevation in her ALT at 48. The patient was found to have an oral aversion requiring nasogastric tube feeds for a...
متن کاملGastritis duodenitis, and circulating levels of gastrin in duodenal ulcer before and after vagotomy.
Biopsy specimens have been taken from five standard sites in the stomach and from the duodenal bulb in order to investigate the association of gastritis and duodenitis with duodenal ulcer. Twenty patients with chronic duodenal ulcer were investigated in this manner and in addition had gastric secretion tests and a radio-immune assay of serum gastrin under differing conditions. The patients were...
متن کاملSTOMACH Helicobacter pylori infection induces duodenitis and superficial duodenal ulcer in Mongolian gerbils
Background: There is no direct evidence for an animal model of Helicobacter pylori induced duodenal ulcer. Aim: In this study we evaluated the roles of bacterial strain and age of experimental animals in induction of duodenitis and duodenal ulcer in Mongolian gerbils after H pylori infection. Methods: Specific pathogen free Mongolian gerbils were inoculated orally with three bacterial strains (...
