[Changes in the concentration of biogenic monoamines in different brain regions under the influence of...

The authors administered 50 mg/body weight of centrophenoxine in white rats i.p. for five susseccive days. The content of serotonine in the cerebral cortex, brain stem and cerebellum increased statistically significant in the rats, injected with centrophenoxine. The levels of noradrenaline and dopamine in the brain stem were raised also significantly. Centrophenoxine did not alter the content of cyclic AMP and the activity of phosphodiesterase in the cerebral cortex and brain stem. These data gave foundation to the authors to suggest that in the mechanism of action of centrophenoxine a significant role is given to the changes, induced by this preparation in the content of biogenic amines in the brain stem.
