Intracerebroventricular angiotensin II increases intraoral intake of water in rats.

abstract：:Intracerebroventricular injections of rat hypothalamic growth hormone-releasing factor (rhGRF) were examined for effects on food intake in free-feeding rats. It was found that, in picomole doses, rhGRF had a stimulatory effect on food intake. Examination of higher doses of rhGRF revealed a decrease in the facilitatory...
