Abstract:
:The concentration of epinephrine, norepinephrine, dopamine, met-enkephalin-, ACTH-, calcitonin- and somatostatin-like immunoreactivity (IR) were determined in the extracts of 9 adrenal pheochromocytomas from 7 patients. Six of these patients had Sipple's syndrome. There was a close correlation between the amounts of met-enkephalin-IR and of epinephrine present in the tumor tissue (p less than 0.01). Such a correlation was not found between catecholamines and the other polypeptide hormones investigated. The relevance of the close parallel in the occurrence of met-enkephalin-IR and epinephrine in human adrenal pheochromocytoma tissue is unknown, but it underlines earlier observations in the normal bovine and rat adrenal medulla on a co-storage and co-release of these substances in normal circumstances.
