Pretreatment with two specific ANG II receptor antagonists, [octanoyl-Leu8]ANG II and [Leu8]ANG II, significantly reduced ANG II-induced water and saline intake. This inhibition lasted approximately 30 min, with partial recovery at 60 min. In rats with electrolytic lesion of the bilateral ventromedial nucleus of hypothalamus (VMH), the effect of ANG II on water intake was not different from that observed in sham rats, but saline ingestion increased. In summary, the present results show that the AV3V region is an important central structure for ANG II-induced saline ingestion. Lesion of the VMH increases the response to ANG II, showing an interaction between the AV3V region and the VMH in the regulation of salt ingestion.R647-R651engSALT INGESTIONWATER INGESTIONANGIOTENSIN-II ANTAGONISTSArtigoWOS:A1991GE63800067Acesso restrito655123693629569715486261941136651023597870118105
