title: Adult offspring long-term effects of high salt and water intake during pregnancy.
abstract: Offspring from dams subjected to hypereninemia, hyperdipsia, and natriophilia by partial aortic ligation (PAL) showed a long-term modification of their ingestive behavior. These rats, upon reaching adulthood, showed an increased appetite for low-concentration saline solutions (0.1 M) when compared to control rats. They also presented a high intake of a medium concentration NaCl solution (0.45 M) after having been offered a very aversive highly concentrated NaCl solution (1.0 M) along with water for 2 days. An increase was also observed in their salt/water intake ratio following two different thirst challenges, 24-h fluid deprivation or sodium depletion by furosemide treatment. The demonstration of the long-term effect of pregnancy history on salt preference in adult offspring draws attention to the possible physiopathological aspects that may be of relevance, considering the well-established relationship between salt intake and hypertension, a disease most commonly occurring in the adult and aged population.
