Vasopressin Effect on Urinary Concentration in Rats with Hereditary Hypothalamic Diabetes Insipidus (Brattleboro Strain).

Abstract
Summary When given large doses of vaso-pressin tannate in oil, rats with hereditary hypothalamic diabetes insipidus at first do not concentrate urine normally. This defect is progressively corrected as daily injections of hormone are continued for 4 weeks.
