微波、噪声、振动条件对脑单胺类含量的影响

本文观察了急性或慢性微波、噪声、振动条件下小鼠、家兔脑单胺类递质含量的变化。结果表明,急性噪声条件下小鼠间脑和脑干5-HT含量明显升高,DA含量有升高趋势;急性振动时,家兔下丘脑NE含量明显升高。慢性微波照射条件下,小鼠全脑5-HT含量明显下降,慢性噪声作用下间脑和脑干DA、NE呈下降趋势,我们还初步分析了上述结果与临床微波作业人员的职业病症状间的关系。

The Effects of Microwave.Noise.Vibration on Monoamine Neurotransmitters of Brain

We observed the changes of contents of 5 -hydroxytryptmine( 5 -HT), norepinephrine (NE) and dopamine (DA) in brain of mice and rabbits which exposed to short-term or long-term microwave. noise and vibration. The results suggested that the contents of 5 -HT increased significantly and DA tented to increase inbrain stem and diencephalon of mice expposed to short-term noise. Under the envi roment of short-term vibration, the contents of NE in hypothalamus of rabbits increased significantly. In the whole brain of mice exposed to long-term microwave radiation 5 -HT decreased significantly incontents. The contents of DA, NE in brain stem and diencephalon of mice tended to decrease when exposed to long-term noise.In this paper the relationship between the microwave workers clinical symptoms and our experimental results has been discussed.
