Effect of glucocorticoids on gastrin secretion in man. | In order to investigate the effect of glucocorticoids on gastrin secretion, plasma gastrin levels were measured by radioimmunoassay in patients with Cushing's syndrome and those treated with glucocorticoids. Fasting plasma gastrin levels were significantly higher in these patients than in normal subjects, with exaggera... | 624,499 | [
