a Fluid intake, urinary output, serum sodium levels and DDAVP treatment in the patient’s pregnancy course. The open, gray and closed column represents fluid intake, urinary output and net water balance, respectively. b Temporal changes of serum and urinary osmolality in pregnancy course of the patient. c Transverse T1-weighted MRI imaging obtained right after delivery. d Protein samples were prepared using placental tissues from the patient and a gestational age-matched control subject, and were subjected to western blotting for vasopressinase expression. Placental protein samples were isolated and prepared from two independent parts from these subjects. e Protein samples were prepared using serum from the patient at different time points, and were subjected to western blotting for vasopressinase expression
