A: in vivo, effects of renal pelvic administration of the ETB-R antagonist BQ788 on the ERSNA and ARNA responses to placing the rat's tail in 47°C water in rats fed HNa diet. B: effects of renal pelvic administration of the ETA-R antagonist BQ123 on the ERSNA and ARNA responses to placing the rat's tail in 49°C water in rats fed LNa diet. **P < 0.01 vs. baseline; ‡P < 0.01, ARNA responses to thermal cutaneous stimulation in the absence and presence of renal pelvic perfusion with BQ788 (A) and BQ123 (B).
