Dynorphin-(1-13), a recently isolated opioid peptide stimulates food ingestion in rats after intracerebroventricular administration at doses of 1 and 10 μg. The latency until food ingestion is 22.4 ± 1.9 min. The ability of dynorphin-(1-13) to initiate food ingestion is antagonized by the opiate antagonist, naloxone. The food ingestion is accompanied by excessive grooming behavior.
