1 Neuronal nitric oxide synthase inhibition sensitizes the tubuloglomerular feedback mechanism after volume expansion  Russell Brown, Anna Ollerstam, A. Erik, G.

2 Figure 1 Proximal tubular stop-flow pressure at different rates of tubular perfusion. Curves are results of fitting of normalized data from rats in a normovolemic control situation (NC) and after 5% extracellular volume expansion (VEC) (A), and from rats treated with combinations of 5% VE and intratubular infusion of Nω-nitro-L-arginine methyl ester (L-NAME) (VEL-NAME) (B), or intraperitoneal administration of 7-nitro indazole (7-NI) (VE7-NI) (C).

3 Figure 2 Single nephron glomerular filtration rate (SNGFR) measured at loop perfusion rates of 0 and 40 nL/min under normovolemic control conditions (NC) (A), after 5% extracellular volume expansion (VEC) (B), and after treatment with combination of 5% VE and intratubular infusion of Nω-nitro-L-arginine methyl ester (L-NAME) (VEL-NAME) (C), or of 5% VE and intraperitoneal administration of 7-nitro indazole (7-NI) (VE7-NI) (D).*P < 0.05 vs. VEC.
