title: Influence of imipramine on neuropeptide Y immunoreactivity in the rat brain.
abstract: The effects of treatment with the antidepressant drug imipramine on neuropeptide Y immunoreactivity were studied immunocytochemically in the rat brain cortex and hypothalamus. It was found that the level of neuropeptide Y immunoreactivity in the cortex was significantly lowered three and 24 h after the last dose of chronic (14 days) imipramine administration as well as 3 h after acute administration. A tendency to decrease neuropeptide Y immunoreactivity was also found in the hypothalamus. The results obtained suggest an important role of the cortical neuropeptide Y in the action of the drug.
