Estimated plasma renin activity expressed as ANG I generation and plasma NE content listed for naïve Sprague-Dawley rats and Sprague-Dawley rats receiving a subcutaneous infusion of 600 ng/min NE maintained on a normal or high-salt diet for 14 days

Treatment	PRA Expressed as ANG I Generation, ng·ml−1·h−1	Plasma NE, nmol/l
Naïve 0.6% NaCl	5.1 ± 0.3	61.6 ± 4.5
Naïve 8% NaCl	1.8 ± 0.3	36.7 ± 4.2*
NE 0.6% NaCl	1.3 ± 0.2	104.3 ± 8.2τ
NE 8% NaCl	0.8 ± 0.1	118.4 ± 7.3ϕ

Data are expressed as means ± SE (n = 5/group). PRA, plasma renin activity.

^*P < 0.05 respective group 0.6% NaCl group value, τP < 0.05 vs. naïve 0.6% NaCl group value. ϕP < 0.05 vs. naïve 8% NaCl group value.
