噪声对鼠脑内5-羟色胺(5-HT)代谢的影响

本文分析了静适应和不同类型的噪声对615鼠和小白鼠脑内5-HT代谢的影响.静适应可引起大多数615鼠脑内5-HT代谢显著性下降15.1%和19.6%.连续脉冲噪声可使其脑内5-HT代谢显著性增高10.2%和22.5%.静适应和连续脉冲噪声对大多数小白鼠脑内5-HT的代谢无显著性影响.但是优势频率为125-250Hz的低频杂乱噪声和粉红噪声都可引起静适应小白鼠脑内5-HT代谢显著性增高,分别增高29.0-39.7%和28.0-32.7%.

THE EFFECTS OF NOISE ON THE METABOLISM OF SEROTONIN(5-HT) IN BRAIN OF MICE

In this paper, the effects of silent acclimation and noise of different types on the metabolism of 5-HT in brain of 615 mice and white mice have been analysed.The silent acclimation can cause a significant decrease of the metabolism of 5-HT in brain in most of 615 mice by 15.1% and 19.9%. A significant increase of the metabolism of 5-HT is induced by the continuous pulse noise. It increases by 10.2% and 22.5%, respectively.In most of white mice, the metabolism of 5-HT are not affected by silent acclimation and the continuous pulse noise. But the low frequency random noise with the dominant frequency at 125-250Hz and the pink noise can both cause a significant increase of the metabolism of 5-HT in brain of them, and it has increased by 29.0-39.7% and 28.0-32.7%, respectively.
