title: [The significance of the determination of catecholamines and their metabolites in neuroblastomas].
abstract: A method for the determination of catecholamines and their metabolites in the urine was established. The specimens were previously cleaned by ion exchangers and the components were separated by a 'reversed phase' ionic pair chromatography, determined by an electrochemical 'wall-jet'-detector. This method was applied in order to find a diagnostic marker in case of neuroblastoma diseases. In 85 per cent of the patients (n = 13) we stated an increased ejection of dopamine.
