Summary
The levels of total and free tryptophan were determined in the plasma of 34 endogenous depressives, 20 neurotic depressives and 25 healthy volunteers. Whilst the levels of total tryptophan were not different in the three groups, the level of free tryptophan was reduced in both endogenous and neurotic depressives. No difference could be found between endogenous and neurotic depressives.
Zusammenfassung
Gesamt- und freies Tryptophan wurde im Plasma von 34 endogen Depressiven, 20 neurotisch Depressiven und 25 gesunden Kontrollpersonen bestimmt. Während beim Gesamttryptophan kein Unterschied zwischen den drei Gruppen festgestellt werden konnte, war das freie Tryptophan bei endogen Depressiven und neurotisch Depressiven signifikant erniedrigt. Zwischen endogen und neurotisch Depressiven fand sich kein Unterschied.
