Relationships between hormonal secretions from the GI tract and gastric functional and/or pathological abnormalities could be studied according to 2 main lines : 1) gastric secretory changes could be the main symptom of hormonal secretory tumors, i.e. acid hypersecretion in the Zollinger Ellison syndrome, acid hyposecretion in pancreatic cholera and in somatostatinoma. In these cases, hormonal hypersecretion is directly responsible for the functional disturbances and the related symptoms; 2) gastric pathological conditions are sometimes accompanied by changes in hormonal secretion, but the level of interdependence is variable : high blood gastrin is directly depending upon the atrophic gastritis in pernicious anemia; this mechanism was also suggested in case of gastric carcinoma. Concerning ulcer disease, numerous problems are unsolved in respect to blood gastrin (basal and stimulated) abnormalities, as well as somatostatin and GIP secretions.
