Localization and identification of catecholamines in the nervous system of Diphyllobothrium dendriticum (Cestoda).

In the central and peripheral nervous system of larval and adult Diphyllobothrium dendriticum, catecholamines were detected using the glyoxylic acid-induced fluorescence method. High-pressure liquid chromatography (HPLC) analysis revealed the presence of dopa (about 65 ng/g fresh weight) and dopamine (5 ng/g fresh weight).
