[Gastroduodenal incretory cells in duodenal ulcer with different levels of gastric secretion].
Immunomorphological PAP method was used in 20 patients with duodenum ulcer and in 10 control individuals to study gastrin (G)-, somatostatin (D)- and calcitonin-gene-related peptide (CGRP) cells in biopsies of the stomach and duodenum. The gastrin and pepsinogen level in the blood, basal and acid production stimulated by pentagastrin were also studied. All patients are subdivided into two groups by their acid production: those with hypersecretion and those with normal secretion. The group with hypersecretion was not homogeneous: some patients had deficiency of D-cells (sometimes in combination with G-cell hyperplasia) and others had a relative and absolute decrease of the number of CGRP cells in combination with foci of parietal cells in pylorus. These patients showed a tendency to the hypergastrinemia and significant hyperpepsinogenemia I in the blood. Stomach hyperplasia in the duodenum, multiple duodenal ulcers, erosive gastroduodenitis and ulcers in close relatives occurred more frequently in these patients. G- and CGRP cells are found to be similar in the form and localization. It is not excluded that G-cell contains, apart from gastrin 1-17, calcitonin-gene related peptide.
