Abstract
The content of tryptophan in a precooked corn meal and in 4 types of selected corn seeds: Zea mays indurata, identata, opaque/2 and Marano synth., has been determined by three different methods: ion-exchange chromatography, spectrofluorometry and spectrophotometry. This content is very low, less than 0.080% d.w. Alimentation for 4 d with a diet composed of precooked corn meal with a tryptophan content less than 0.025% induced the appearance of aggressive-cidal or aggressive non-cidal behaviour towards the mouse in more than half of Wistar rats bred in a room constantly lighted by a sodium steam light. The appearance of this behaviour is probably connected with a decrease in brain serotonin.
