本文分析了３０例儿童多动综合征（ＭＢＤ）血清单胺类神经递质的含量，并与弱智儿童（ＭＲ）进行了比较。结果表明，ＭＢＤ组儿茶酚胺（ＣＡ）含量非常显著高于正常儿童，而５－羟色胺非常显著低于正常儿童，与ＭＲ组相比，ＭＢＤ组儿茶酚胺非常显著高于ＭＲ组，５－羟色胺无显著差异，但其代谢产物５一羟吲哚乙酸非常显著高于ＭＲ组。提示ＭＢＤ儿茶酚胺系统代谢活跃，很可能是导致患儿动作活动过度的原因，而ＭＢＤ和ＭＲ两组ＣＡ呈现相反趋势，正是神经信息传递发生障碍时兴奋和抑制出现不同紊乱状态的反映；ＭＢＤ５－羟色胺系统代谢特点可能是导致患儿注意力不集中、易冲动的原因之一。
In this paper, the levels of monoamine neurotransmitters in 30 children with hyperactivity disorder (MBD) were analyzed and compared with those of mentally retarded children (MR). The results showed that the content of catecholamine (CA) in MBD group was significantly higher than that in normal children, but the level of serotonin in MBD group was significantly lower than that in normal children. Compared with MR group, the catecholamines in MBD group were significantly higher than those in MR group , But its metabolite 5-oxoacetic acid was significantly higher than the MR group. It is suggested that the metabolism of MBD catecholamines is active and may be the cause of over-action in children, while the CA of MBD and MR shows the opposite trend, which is the reflection of excitement and inhibition of different disorders in the neuronal transmission of information. MBD5- Serotonin system metabolic characteristics may lead to children’s attention is not focused, easy to impulse one of the reasons.
