Nitric oxide synthase (NOS) activity in cerebellum, renal cortex, and medulla

Group	Cerebellar NOS Activity	Renal Cortex NOS Activity	Renal Medulla NOS Activity
Control NS	29.27 ± 3.56 (100 ± 1)	0.79 ± 0.07 (96 ± 3)	0.88 ± 0.12 (84 ± 1)
Control HS	22.50 ± 4.31 (99 ± 2)	0.91 ± 0.14 (92 ± 2)	1.13 ± 0.19 (87 ± 2)
AG + NS	27.33 ± 7.90 (101 ± 1)	0.65 ± 0.11 (95 ± 2)	1.08 ± 0.07 (87 ± 1)
AG ± HS	28.85 ± 10.74 (102 ± 1)	0.65 ± 0.09 (94 ± 2)	1.06 ± 0.06 (89 ± 1)
NS-2	ND	1.22 ± 0.12	1.40 ± 0.16
HS-2	ND	0.92 ± 0.12	1.46 ± 0.18

NS = normal salt intake (~0.6%; NS); HS = high NaCl intake (~6%) for 14 days; AG = rats chronically given AG by gavage (250 mg/kg/day) for 14 days; NS-2 and HS-2 = additional groups of rats fed normal salt (NS-2) and high salt (HS-2) diets, and studied for baseline renal NOS activity only; other abbreviations as in Table 1.

Data given as mean ± SE. Percent inhibition with L-arginine analogs given in parentheses. No values were different from control.
