title: Opioid peptide effects on feeding in rabbits.
abstract: The food intake of rabbits was measured after intracerebroventricular injections of several opioid agonists and naloxone. The preferential kappa agonist dynorphin A increased intake, while naloxone, [D-Ser2,Leu5]enkephalin-Thr6 and Tyr-D-Ala-Gly-(Me)Phe-Gly-ol reduced intake or had no effect. These results suggest that kappa receptors have a role in the control of feeding in rabbits.
