[Investigations concerning the hypothalamic-hypophysial regulation of aldosterone secretion (author's transl)]

In 17 patients with retrospectively healthy adrenals we performed a LHRH-test, a TRF-test and an ACTH-test in the short modification. Additionally we determined plasma aldosterone and renine levels. Concerning the LHRH-tests and the TRF-tests we did not find any differences on the aldosterone values. Concerning the ACTH-tests in the short modification we found an increase of the aldosterone values which resembled that of the cortisol levels (increase of cortisol 104.7%, increase of aldosterone 93.3%). The renin values remained unchanged. Therefore the plasma aldosterone levels are modified in accordance with the cortisol levels by hypophysial influences.
