β-/Tyr9/melanotropin-/9-18/ administered intracerebroventricularly /icv./ in doses of 1 μ/rat or 10 μg/rat had no influence on the substantia nigra lesion-induced turning activity of rats, however, it was able to potentiate apomorphine-induced contralateral turning. In a dose of 20 μg/rat /icv./ the peptide alone induced clear contralateral turning. The results suggest that at lower doses the peptide facilitates apomorphine-induced dopamine receptor stimulation, while in a higher dose the peptide alone can stimulate dopamine receptor activity.
