Mean arterial blood pressure (MAP) and plasma renin activity (PRA) during normal salt (NS) or high salt (HS) diet in sham operated controls and rats with 2 kidney–1 clip (2K1C) hypertension

Experimental Group	MAP (mm Hg)	PRA (ng angiotensin I/ml/h)
NS sham	110±1 (7)	2.92±0.48 (9)
HS sham	121±2 (8)	1.54±0.38 (11)
NS 2K1C	133±4 (10)*	4.51±0.54 (14)*
HS 2K1C	143±7 (10)*	0.92±0.20 (8)**

*Significantly different (P < 0.05) vs. sham-operated controls on the same diet. **Significantly different (P < 0.05) from NS diet within the same experimental group. Numbers in parentheses indicate the number of animals.
