DS8% rats: Dahl salt-sensitive rats fed an 8% NaCl diet; DS0.4% rats: Dahl saltsensitive
rats fed a 0.4% NaCl diet; DR8% rats: Dahl salt-resistant rats fed an
8% NaCl diet; DR0.4% rats: Dahl salt-resistant rats fed a 0.4% NaCl diet. MAP:
mean arterial pressure; HR: heart rate; RSNA: renal sympathetic nerve activity,
expressed as a %. The maximum RSNA (100%) was obtained by release of
baroreflex-mediated inhibition by caval occlusion. *: p < 0.05 between the S8%,
S0.4%, R8%, and R0.4% rat groups. The S8% rats show marked hypertension,
but the RSNA level of the group does not show any difference between the four
rat groups [28]. |
