Radio gel and affin chromatography were used to study big gastrin interaction with blood proteins of man and animals. The experiments showed that big gastrin interacts with serum proteins in vitro. The gastrin-blood protein complex is labile and readily dissociates (T 1/2 = 8--14 min). A more stable complex is found in acidic medium. Ceruloplasmin is one of the blood serum proteins able to interact with big gastrin. The stability of hormone-protein complex, formed by gastrin and ceruloplasmin, is dependent upon hormone concentration. With the addition of C-terminal penta--and octapeptides to labelled hormone, binding increased. It is speculated that formation of labile gastrin-blood protein complexes is necessary for selective gastrin transport from hormone-producing cells to target cells.

The effects of somatostatin (growth hormone release inhibiting hormone) on basal gastrin were studied in patients suffering from pernicious anaemia and chronic renal and liver disease, and during sequential arginine/insulin-stimulated gastrin release in normal subjects. When basal gastrin concentrations were normal (10-50 pg/ml) in controls and in patients who were in renal and liver failure, somatostatin had no effect on gastrin levels. Raised basal gastrin levels in pernicious anaemia and in 2 cases of chronic renal disease, were significantly inhibited by somatostatin with a half-life (T 1/2) of 3-4 minutes. Arginine infusion caused an insignificant rise in serum gastrin which was unaffected by somatostatin, whereas insulin hypoglycaemia significantly stimulated gastrin release, which was inhibited by somatostatin.
