HISTORY OF TEACHING ABOUT NERVOUS TROPHISM

Concepts <<trophism>> and <<nervous trophism>>, development of views on trophic function of the nervous system and its disorders (neurogenic dystrophies) are reviewed. The problem on the ways of the trophic effects of the nervous system on the tissues is considered. The role of neuromediators in this process, particularly the significance of balance of norepinephrin, (NE), a mediator of the sympathetic nervous system (SNS), for maintaining trophism of tissues, their structure and fuctions is emphasized. The activating role of SNS and NE in the resistence and reparative regeneration of different tissues is shown under the experimental and clinical conditions. In this view a comprehensive definition of concepts <<nervous trophism>> is given.
