Why the study?

Does high-salt intake alter the course of the development and magnitude of hypertension or influence renal function in two-kidney, one clip Goldblatt hypertensive rats?

Population

Two-kidney, one clip (2K1C) Goldblatt hypertensive rats

Comparison

0.9% sodium chloride as a drinking solution for… vs Water-drinking clipped rats and control animals

Design

Preclinical

Follow-up

3 weeks

Implication

High-salt effects in this 2K1C model should not change clinical practice; leaves open translation to human renovascular hypertension.

Structured PICO

Does high-salt intake alter the course of the development and magnitude of hypertension or influence renal function in two-kidney, one clip Goldblatt hypertensive rats?

P
Population
Two-kidney, one clip (2K1C) Goldblatt hypertensive rats
I
Intervention
0.9% sodium chloride as a drinking solution for 3 weeks
C
Comparator
Water-drinking clipped rats and control animals
O
Outcome
Arterial blood pressure and renal function (plasma renin activity, kidney renin content, urine flow, glomerular filtration rate, and sodium excretion rate)surrogate

In a 2K1C renovascular hypertension rat model, high-salt intake suppresses the renin-angiotensin system and delays the onset of hypertension without affecting its final magnitude, while improving function in the clipped kidney.
