Studies were made on histochemical changes of the human adrenals. There was no great difference in histochemical findings between essential hypertensive patients and normotensive subjects.
In zona glomerulosa, enhanced activities of enzymes were remakrably observed in case of renal hypertension.
In primary aldosteronism, hypertrophy occured to the non-tumorous portion in case of the zona glomerulosa and increased enzymatic activity was recognized in this zone.
Adrenocortical hyperplasia with clinical evidence of Cushing's syndrome, the zona glomerulosa exhibited too complicated histochemical changes to demonstrate any distinct conclusions.
