[On the ACTH-corticoid relation in essential hypertension in dependence of plasma-renin activity (PRA) (author's transl)].

Patients with essential hypertension were studied for the reaction of the hypophyseal-adrenal-system before and during insulin hypoglycemia test. We found in our results that the mean total corticoid levels in plasma of hypertensive patients with low or high PRA are significantly higher than control levels. In insulin hypoglycemia test the mean corticoid levels of patients with normal and high PRA do not differ from the mean levels found in normal individuals whereas hypertensive patients with low PRA have significant lower plasma corticoid levels.
