title: Effect of vasoactive intestinal peptide on dopaminergic system in the rat brain.
abstract: The present study analyzed the effect of vasoactive intestinal peptide (VIP) on the content of dopamine (DA) and its main metabolite, DOPAC, in the rat brain. Intracerebroventricular administration of VIP increased the DA and DOPAC content, causing a dose-dependent increase in the DOPAC/DA ratio in various regions of the brain. The results suggest that VIP facilitates the DA metabolism in the brain.
