Interaction between hypothalamic peptides in a superfused pituitary cell system.

abstract：:Rats with dorsomedial hypothalamic lesions (DMN-L) or sham operations were injected IP with saline or the satiety peptide cholecystokinin (CCK) at 3.0 and 6.0 micrograms/kg at the onset of the dark phase. Food consumption was then measured 15, 30 and 60 min later. Compared to saline baseline intake, CCK suppressed fee...
