title: [Catecholamine content of tumors of the gastrointestinal tract].
abstract: The levels of catecholamines (adrenaline, noradrenaline, dopamine) in gastrointestinal tumors and normal tissue adjacent to malignant tumor were studied. Noradrenaline level in tumor was considerably lower than that in normal tissue. Neither adrenaline nor dopamine level showed any changes. It was established that tumor development occurs against the background of functional desympathization and adverse changes in the ratio of mediator and hormonal links in tissue sympatho-adrenal system.
