    Abstract:
    The paper is concerned with the results of a study of the aldosterone concentration and renin activity, the general level of catecholamines and their fractions (epinephrine, norepinephrine and dopamine) in the peripheral blood and blood taken at selective venography from the vena cava inferior, renal and adrenal veins of 108 patients with hypertension, aldosteroma and idiopathic hyperaldosteronism, adrenal and extraadrenal pheochromocytoma, renovascular and renoparenchymatous arterial hypertension. The aldosterone concentration and renin activity were determined with radioimmunoassay, and the general content of catecholamines and their fractions with a radioenzymatic method using standard kits. It has been shown that the radioimmunoassay to determine the aldosterone concentration and renin activity in the blood from the vena cava inferior, renal and adrenal veins makes it possible to resort to differential diagnosis of hypertension, aldosteroma, idiopathic and secondary hyperaldosteronism. A considerable increase in the blood plasma renin activity on the affected side was revealed in the patients with renovascular hypertension, and in renoparenchymatous hypertension it was equal in both renal veins. The study of the total content of catecholamines and their fractions in the blood from different parts of the venous system can be used for topical diagnosis of adrenal and extraadrenal pheochromocytoma.
