1 A high salt intake reduced the nNOS-mRNA gene expression in the PH (from 100 +/- 2.4 to 46 +/- 1.0;p < 0.01), LC (from 92 +/- 1.9 to 69 +/- 1.2; p < 0.01) and PVN (from 63 +/- 0.8 to 46 +/- 1.3) of CRF rats. Salts nitric oxide synthase 1 Rattus norvegicus
2 High salt intake significantly reduced the nNOS-mRNA gene expression in the mesenteric arteries of control rats, but not in those of CRF rats. Salts nitric oxide synthase 1 Rattus norvegicus
3 In conclusion, these studies provide evidence that in control and CRF rats, high salt intake inhibits nNOS-mRNA expression in the brain, resulting in activation of the sympathetic nervous system and higher blood pressure. Salts nitric oxide synthase 1 Rattus norvegicus
