The urinary corticosterone/11-dehydrocorticosterone ratio and corticosterone concentration were higher in SS rats than in SS-13BN rats. Rats had been on the 4% NaCl diet for 3 days. A: the urinary corticosterone/11-dehydrocorticosterone ratio was significantly higher in SS rats than in SS-13BN rats. *P < 0.05 vs. SS; n = 7. B: corticosterone concentration in 24 h urine was significantly higher in SS rats than in SS-13BN rats. *P < 0.05 vs. SS; n = 7. C: plasma levels of corticosterone were not significantly different between SS and SS-13BN rats; n = 5.
