Effects of thermal cutaneous stimulation on MAP, HR, ERSNA, and ARNA in rats fed a low- and high-sodium diet during vehicle administration

	Low-Sodium Diet	High-Sodium Diet
n	33	8
ΔMAP, mmHg/s	3370 ± 260*	5220 ± 920*†
ΔHR, beats·min−1·s	22,010 ± 2390*	35,090 ± 6650*†
ΔERSNA, %·s	7920 ± 860*	12,910 ± 3780*
ΔARNA, %·s	2220 ± 450*	5670 ± 1260*‡

Responses of mean artierial pressure (ΔMAP), heart rate (ΔHR), efferent renal sympathetic nerve activity (ΔERSNA) and afferent renal nerve activity (ΔARNA) are expressed as area under the curve of MAP, HR, ERSNA, and ARNA, respectively, vs. time.

^*P < 0.01 vs. baseline;

^†P < 0.05;

^‡P < 0.01 vs. low-sodium diet.
