title: Gastrin and somatostatin in plasma and gastric biopsy specimens in pernicious anemia.
abstract: Five patients with megaloblastic anemia due to deficiency of vitamin B12 and achlorhydria and six normal controls participated in the study. The patients with pernicious anemia (PA) had elevated plasma gastrin levels, as expected, and lower plasma somatostatin (SST) levels than the control patients. The amount of gastrin and SST in the antral mucosa did not differ in the two groups of patients. In the fundic mucosa, the patients with PA had increased tissue concentrations of both gastrin and SST as compared with the tissue concentrations in the controls. These findings of hormone tissue concentrations were correlated to the number of argyrophilic cells. Thus, in the antral mucosa the number of argyrophilic cells did not differ in patients with PA and in the controls. In the fundic mucosa, however, the number of argyrophilic cells was significantly elevated in patients with PA as compared with the controls.
