Vasopressin and renin-angiotensin hormonal axes in the PCK rats after dietary treatment. (a,b) Shown are urinary copeptin (a) and circulating (plasma) Ang II (b) levels at the end of the 8 week long dietary treatment in the PCK rats fed a SD and a NS diet (for copeptin) or SD, NS and HS diets (for Ang II). Copeptin levels were undetectable in the urine of the HS diet fed PCK animals. (c) Aldosterone levels in the urine and plasma of the PCK rats fed a SD, NS and HS diets. Values were compared using a one-way ANOVA with a Tukey post-hoc test. In box plots, the box is SEM, whiskers represent SD, and line within the box shows median value.
