Chronic gastritis and gastric ulcer

Chronic gastritis and gastric ulcer.

Gastric ulcer and gastritis.

The gastritis associated with chronic gastric ulcer has been studied by means of biopsy specimens taken under vision through a fibreoptic gastroscope from four standard sites in the stomach. Observations have been made in patients with untreated gastric ulcer and also in patients after medical or surgical treatment of the ulcer. The gastritis is usually widespread in chronic peptic ulcer of the...

Gastric ulcer and regurgitation gastritis.

Experimental and clinical data have incriminated excess gastric acid secretion as an important factor in the development of duodenal ulcer. On the other hand, gastric ulcer is characteristically associated with normal to low levels of acid secretion, and mucosal resistance factors have been invoked to explain the pathogenesis. The purpose of this report is to summarize the evidence favouring th...

Genetic alterations in benign lesions: chronic gastritis and gastric ulcer.

AIM To investigate the occurrence of chromosome 3, 7, 8, 9, and 17 aneuploidies, TP53 gene deletion and p53 protein expression in chronic gastritis, atrophic gastritis and gastric ulcer, and their association with H pylori infection. METHODS Gastric biopsies from normal mucosa (NM, n=10), chronic gastritis (CG, n=38), atrophic gastritis (CAG, n=13) and gastric ulcer (GU, n=21) were studied us...

Chronic gastritis, alcohol, and non-ulcer dyspepsia.

An investigation of 102 men comprising alcoholics, patients with non-ulcer dyspepsia, and healthy controls is reported. It demonstrates that alcohol is a cause of chronic gastritis and the severity of the mucosal lesion is directly related to the duration of excess drinking. Contrary to popular belief, chronic gastritis does not give rise to symptoms. The effect of alcohol on the gastric mucosa...
