Abstract:
:The role of dopamine (DA) in the rat locus coeruleus (LC) was investigated by determining the levels of 3,4-dihydroxyphenylacetic acid (DOPAC), DA and noradrenaline (NA) in the LC after pharmacological treatments by pargyline, haloperidol, 6-hydroxydopamine (6-OHDA) and desmethylimipramine (DMI). The DA, DOPAC and NA contents of the LC were determined by high pressure liquid chromatography. Fifteen days after 6-OHDA, the DOPAC and NA levels were reduced by 60%, but they remained constant after 6-OHDA + DMI. Pargyline provoked highly significant increases in DA and NA but reduced DOPAC to non-measurable amounts. haloperidol caused a 54% decrease in the DOPAC levels. Pargyline and haloperidol administered to rats having received 6-OHDA + DMI 15 days before, caused similar effects on DA, DOPAC and NA levels as those in non-treated rats. It is suggested that DOPAC is mainly located in noradrenergic neurons, thus eliminating the possibility of a significant DA cell body population in the rat LC.
