摘要
调查157名在燃煤型地氟病区出生和长大的12~13岁儿童,并作动物高氟摄入实验。结果发现:从童年早期开始的长期高氟摄入会引起儿童脑力工作能力降低;长期摄入高氟的儿童发锌含量下降。多元相关分析表明,儿童脑力工作能力与发锌呈正相关。同时,长期高氟摄入的动物脑中5—羟吲哚乙酸降低和去甲肾上腺素增高,这可能是使儿童脑力工作能力降低的作用机理,需进一步实验证实。
We made an investigation in 157 chil- dren,aged 12 13 ,born and grew up in a coal burn-ing pattern endemic fluorosis area and an experimenton excessive fluoride intak in rat.The resultsshowed:(1)Excessive fluoride intake since early child-bood would reduce mental work capacity(MWC) andhair zinc content;(2)The effect on zinc metabolism was a mechanism of influence on MWC by excessivefluoride intake ;(3)Excessive fluoried intake de-creased 5-hydroxy indole acetic acid and increasednorepinephrine in rat brain;whether this is also amechanism of the influence on MWC awaits awaits confirma-tion.
