Effects of synthetic atrial natriuretic factor (ANF) on renin-aldosterone axis in the conscious newborn calf.

The effects of synthetic atrial natriuretic factor (ANF) on the renin-aldosterone axis were studied in fifteen 4-7 day-old male milk-fed calves divided into 3 groups of 5 animals each. Synthetic ANF intravenous (i.v.

Diuretic, natriuretic and hypotensive effects of synthetic atrial natriuretic factor in conscious newborn calves.

The effects of synthetic Atrial Natriuretic Factor (ANF) on urine flow rate, sodium excretion, potassium excretion and arterial blood pressure were studied in 10-12 days-old female calves. In four female calves fitted with a Foley catheter, an intravenous administration of ANF (Ile-ANF 26; 1.6 micrograms/kg body wt during 30 min) induced an increase (P less than 0.
