Effect of intravenous and intragastric administration of Pi on hormonal levels in PTX rats. PTX rats were loaded with 500 μmol Pi or saline intravenously or orally. (A) Plasma intact PTH, (B) plasma intact FGF23, (C) plasma 1,25-(OH)2-vitamin D3, (D) plasma insulin, (E) plasma dopamine, and (F) urine dopamine. Four profiles are shown: saline intravenous infusion (black), Pi intravenous infusion (red), saline intragastric gavage (green), and Pi intragastric gavage (blue). Data are presented as the means±SEM. ANOVA test; n=4–6 per group and time point. *P<0.05 versus time 0.
