1. Acute severe sodium subtraction (20-25% of total exchangeable sodium) before or during treatment with adrenocorticotrophic hormone (ACTH) does little to modify the increase in blood pressure induced by ACTH. 2. Chronic low salt diet, less than 5 mmol/day, abolishes the blood pressure increase, but the response can be restored by increasing the sodium intake to as little as 10 mmol/day. 3. 17alpha,20alpha-Dihydroxyprogesterone infused concurrently with other adrenal steroids will mimic ACTH hypertension and perhaps represents a new class of steroid capable of influencing blood pressure.

UI MeSH Term Description Entries
D006973 Hypertension Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more. Blood Pressure, High,Blood Pressures, High,High Blood Pressure,High Blood Pressures
D006908 Hydroxyprogesterones Metabolites or derivatives of PROGESTERONE with hydroxyl group substitution at various sites.
D000324 Adrenocorticotropic Hormone An anterior pituitary hormone that stimulates the ADRENAL CORTEX and its production of CORTICOSTEROIDS. ACTH is a 39-amino acid polypeptide of which the N-terminal 24-amino acid segment is identical in all species and contains the adrenocorticotrophic activity. Upon further tissue-specific processing, ACTH can yield ALPHA-MSH and corticotrophin-like intermediate lobe peptide (CLIP).
