Effect of atomoxetine on DA D₂ receptor expression in the hypothalamus.

<p>Upper: Photomicrographs of DA D₂ receptor expression in the hypothalamus. WB: Whole brain. The sections were stained for DA D₂ receptor immunoreactivity (brown). The scale bars represent 50 µm (WB) and 200 µm (A–E). Lower: DA D₂ receptor expression in each group *<i>p</i><0.05 compared to the control group. ^†<i>p</i><0.05 compared to the untreated ADHD group. ^‡<i>p</i><0.05 compared to the untreated ADHD and 0.25 mg/kg/d atomoxetine-treated ADHD groups. The data have been presented as mean ±SEM.
