title: The influence of a high K intake on the hypertensive effect of ACTH and DOC in sheep.
abstract: The effect of 5 days administration of ACTH or DOC, was examined before and after chronic potassium (K) loading in sheep. K loading raised plasma [K], urine volume and K excretion but had no effect on mean arterial pressure (MAP). On a normal K intake DOC (5 mg/day i.v.) increased MAP and plasma sodium [Na]. Plasma [K], urinary Na (day 1) and K (day 1) excretion were decreased. On a high K intake (congruent to 800 mmol K/day), DOC lowered plasma [K] but had no effect on MAP or Na excretion. The hypertensive effects of ACTH were not affected by K intake.
