[Angiotensin II in the organization of rat feeding behavior].
Intraventricular injection of angiotensin-II (100 ng) increased the latency period and decreased the amount of food intake in the hungry rats. Preliminary administration of saralasin (100 ng) blocked the inhibitory effect of angiotensin-II on food consumption. In contrast to the above mentioned intraperitoneal injection of angiotensin-II (10 ng/kg) 10 min before food and water admission results in the tendency to increase the food intake. And the same application of angiotensin-II 60 min before food and water admission increased by 49% of food intake in hungry rats. Saralasin (50 ng/kg) given prior to the angiotensin-II administration blocked the angiotensin-II effects. Moreover a significant decrease in the food intake was found after intraperitoneal injection of saralasin only. No significant changes in the drinking behavior in response to the intraventricular and intraperitoneal drugs administration were registered.
