title: Assay of gastrin and somatostatin in gastric antrum tissues of children with chronic gastritis and duodenal ulcer.
abstract: OBJECTIVE
  To study the expressions of gastrin (GAS) and somatostatin (SS) in gastric antrum tissues of children with chronic gastritis and duodenal ulcer and their role in pathogenic mechanism.
  
  
  METHODS
  Specimens of gastric antrum mucosa from 83 children were retrospectively analyzed. Expressions of GAS and SS in gastric antrum tissues were assayed by the immunohistochemical En Vision method.
  
  
  RESULTS
  The expressions of GAS in chronic gastritis Hp+ group (group A), chronic gastritis Hp-group (group B), the duodenal ulcer Hp+group (group C), duodenal ulcer Hp-group (group D), and normal control group (group E) were 28.50+4.55, 19.60+2.49, 22.69+2.71, 25.33+4.76, and 18.80+2.36, respectively. The value in groups A-D was higher than that in group E. The difference was not statistically significant. The expressions of SS in groups A-E were 15.47+1.44, 17.29+2.04, 15.30+1.38, 13.11+0.93 and 12.14+1.68, respectively. The value in groups A-D was higher than that in group E. The difference was also not statistically significant.
  
  
  CONCLUSIONS
  The expressions of GAS and SS are increased in children with chronic gastritis and duodenal ulcer.
