title: [The effect of the antidiuretic hormone on the renal excretion of urea and electrolytes in fed and fasting sheep].
abstract: The effects of the antidiuretic hormone (ADH) on the renal excretion of urea and electrolytes were studied in sheep, subjected to water stress, before and after 36-hour fasting. The intravenous administration of synthetic lysine-vasopressin (L-VP) at the dose of 100 microgram per kg induced only a temporary, statistically insignificant, drop of the urinary urea outputs by the fed as well as fasting sheep. L-VP did not influence the excretion of sodium and potassium electrolytes either. It follows from the results that there are no differences in the renal response to ADH between the fed sheep and sheep that have fasted for 36 hours.
