The aim of this research is to observe if the lack of cerebral serotonin, obtained by a diet almost devoid of tryptophan (precooked yellow corn meal) is able to trigger the muricide behaviour in male Rats naturally non-muricide. To determine the tryptophan content in the food used and in 4 types of selected maize flour (Zea mays: indurata, indentata, opaque/2 and synt. marano), 3 different methods have been used (ion-exchange chromatography, spectrofluorometry, spectrophotometry). The muricide behaviour, or the interspecific attack, has been tested by comparison Rat-Mouse. The results show that the feeding with a diet "short term" (4 days), composed of precooked corn meal, with a very low content of tryptophan, induces the appearance of muricide or aggressive behaviour towards the Mouse in more than half of the Wistar Rats, bred in a room constantly lighted by sodium steam light. The appearance of the above-mentioned behaviour is connected with the decrease in cerebral serotonin.
本研究的目的是观察通过喂食几乎不含色氨酸（预煮黄玉米粉）的饮食导致大脑血清素缺乏，是否能够引发原本不具有杀鼠行为的雄性大鼠出现杀鼠行为。为了测定所用食物及4种选定玉米粉（硬粒玉米、马齿玉米、粉质型/2玉米和合成马拉诺玉米）中的色氨酸含量，使用了3种不同方法（离子交换色谱法、荧光分光光度法、分光光度法）。杀鼠行为或种间攻击行为通过大鼠-小鼠对比试验进行测试。结果表明，用色氨酸含量极低的预煮玉米粉组成的“短期”（4天）饮食喂养，在钠蒸汽灯持续照明的房间饲养的超过半数Wistar大鼠中，诱发了对小鼠的杀鼠或攻击行为。上述行为的出现与大脑血清素的减少有关。
