Intraventricularly administered 5 μg dopamine, 5 μg norepinephrine or 165 μg melatonin inhibited the activation by surgical stress of the pituitary adrenal system, and increased the hypothalamic serotonin content. p Chlorophenylalanine (300 μg/kg b.w.) prevented the inhibition by monoamines of the stress by lowering the serotonin content in the hypothalamus. According to the results, the inhibition of stress by monoamines is mediated via increased hypothalamic serotonin content.
