[Effector peptides of the brain renin-angiotensin system in central mechanisms of learned and natural forms of drinking behavior in rats].

[Article in Russian]

Abstract

Central mechanisms of angiotensin involvement in initiation and realization of operant forms of drinking behavior were investigated. It was suggested that intracerebroventricular microinjection of angiotensin-II and angiotensin-IIl specifically affected the learned forms of drinking behavior. The experiments demonstrated that [des-Asp1]-angiotensin-I produced only the natural forms of drinking behavior. Angiotensins modulated specific forms of thirst-associated behavior such as exploring, grooming, and ingestive behavior. Injections of AT1 receptor antagonist losartan were associated with acute water intake decrease and sharp operant behavior inactivation.
