  • Title: Effect of atrial natriuretic factor on central angiotensin II-induced responses in rats.
    Author: Nakamaru M, Takayanagi R, Inagami T.
    Journal: Peptides; 1986; 7(2):373-5. PubMed ID: 2942846.
    Abstract:
    The effect of intracerebroventricular (ICV) injection of atrial natriuretic factor (ANF) on drinking and pressor responses induced by centrally administered angiotensin II (AII) was examined in the rat. The ICV injection of ANF attenuated water intake induced by AII or 48-hr water deprivation. In contrast, ANF did not affect AII-induced pressor responses. The ICV injection of ANF did not cause recognizable change in blood pressure in spontaneously hypertensive rats or Wistar-Kyoto rats. These results suggested that ANF in the brain is involved in the central control of water intake. Brain ANF may be considered as a selective antagonist of the dipsogenic effect of AII but not its pressor effect.
