高氟区母亲与其新生儿血浆氟离子浓度关系探讨

STUDY ON THE RELATION OF THE IONICITY OF FLUORINE IN THE BLOOD BETWEEN MOTHERS AND THIER NEW BORN CHILDERN IN THE HIGH FLU ORINE AREAS

为探讨高氟区母亲与其新生儿血浆氟离子(IPF)浓度的关系,证实母体血液通过胎盘流入胎儿体内的过程中,胎盘对氟素有无筛除作用,1984年6～7月我们对高氟区临产孕妇及新生儿 IPF 浓度进行了调查,现将结果报告如下:材料与方法选择梁山县韩岗。

It is not obviously different th-at the average ionicity of fluorinebetween mothers and thier new bo-rn childern in 20 cases in the normalfluorine area and 38 cases in the highfluorine areas reported in the article.It is directly proportional to the f-luorine average between mothers a-nd thier new born childern.So it isdifferent from the result reportedbefore and it is clear that fluorinecan not only pass through placentato the new born childern but theplacentae are not able to silt fluori-ne.It is believed that there is lesspoison in the milk teeth than in t-he permanent teeth and the milk t-eeth are not poisoned as seriously asthe permanent teeth because the milkteeth are poisoned less time than t-he permanent teeth.
