From: Long-term blood pressure control: is there a set-point in the brain?
Contractions evoked by norepinephrine (NE, 10−8 to 10−6 M) in aortic rings of rats in the 4 groups, modified from Ref. [65]. DS-8% rats Dahl salt-sensitive rats fed 8% NaCl diet (n = 10); DS-0.4% rats Dahl salt-sensitive rats fed 0.4% NaCl diet (n = 12); DR-8%, 0.4% rats Dahl salt-resistant rats fed 8 or 0.4% NaCl diet (n = 12, 10, respectively); ED50 half maximal responses, Emax maximum responses. *p < 0.05 between high-salt and normal-salt Dahl salt-sensitive rats
