In vitro responses of focal hyperplastic tissue of the human adrenal zona fasciculata to ACTH.

The temporal cAMP, cortisol and aldosterone responses to ACTH of focal hyperplasia of the zona fasciculata and of normal human adrenocortical tissue were investigated. ACTH significantly increased cAMP levels (1 min) and cortisol output (2 min) in normal adrenal tissue but not in hyperplastic tissue. However, following ACTH treatment cortisol and aldosterone production were depressed in the abnormal adrenal tissue below the untreated or the ACTH stimulated normal adrenal tissue. In addition, basal cortisol and aldosterone production of the hyperplastic adrenal tissue was elevated above that of the normal adrenal tissue. These findings suggest that the cAMP second messenger concept may be only one of several mechanisms in the modulation of human adrenocortical function.

Subcapsular cell hyperplasia and mast cell infiltration in the adrenal cortex of mice: comparative study in 7 inbred strains.

Subcapsular cell hyperplasia (SCH) in the adrenal cortex of aged mice (13-15 months old) was frequent in both sexes of BALB/c, C3H/He, DBA/2J and IQI/Jic mice and in the females of A/J and C57BL/6, although the incidence and severity of SCH were considerably different among mouse strains. Mast cells were closely associated with SCH in the A/J, BALB/c, C57BL/6, DBA/2J and IQI/Jic mice, but not in the C3H/He strain. Compared with other strains, IQI/Jic mice had a significantly larger number of mast cells in the adrenal glands. Our findings suggest that mast cells may participate in the development of SCH, and IQI/Jic would be suitable for studying the pathogenesis of SCH and the role of mast cells in this lesion.

Isolated glucocorticoid insufficiency.

Two cases of isolated glucocorticoid insufficiency or congenital adrenocortical unresponsiveness to ACTH-a variant of adrenocortical failure without mineralocorticoid insufficiency-are presented. Familial incidence was present only in case 1 since two of the siblings died after convulsions, possible related to hypoglycemia. The pathology specimens of one sibling were available for review showing complete lack of the fascicular zone and degenerative changes in the adrenals and evidence of increased ACTH secretion in the pituitary. In the patients who were given substitution therapy with hydrocortisone, studies of plasma renin and aldosterone revealed impairment of plasma aldosterone response to salt restriction, orthostatism and furosemide-induced diuresis combined with postural change. We conclude that in some cases of isolated glucocorticoid insufficiency, impairment of mineralocorticoid function may gradually develop, which is in contrast to the assumption of a congenital defect in the action of ACTH.
