Fig. 4.

Mean arterial pressure at baseline and then during the 5th week on high-salt (4% NaCl diet) in normal protein+sham nephrectomy (Norm. Prot.+Sham NPX; black bar, n = 6); low protein+sham nephrectomy (Low Prot.+Sham NPX; white bar, n = 9); normal protein+uninephrectomy (Norm. Prot.+Uni-NPX, gray bar, n = 6); and low protein+uninephrectomy, (Low Prot.+Uni-NPX, hatched bar, n = 6). Note that mean arterial pressure in the Low Prot. group was salt sensitive and that uninephrectomy exacerbated salt sensitivity in both uninephrectomized groups to a similar degree. *P < 0.05 vs. baseline; †P < 0.05 vs. both Norm. and Low Prot.
