氟能否经胎盘转输的研究始于30年代。由于研究对象及方法的不同,且多为动物实验资料,故未获完全一致的结论。到70年代,人们开始对胎盘,母血、脐带血、羊水间氟水平进行定量研究。80年代初,在氟经胎盘转输的研究基础上,进而开展了氟对胎儿影响的探讨,现将此项研究做一综述。 Fluorine can be transplanted through the placenta began in the 30’s. Due to the different subjects and methods, and mostly animal experimental data, it is not completely consistent conclusion. By the 1970s, people began to quantitatively study the levels of fluoride in placenta, maternal blood, umbilical cord blood and amniotic fluid. In the early 1980s, on the basis of the study of fluorine transplanted through the placenta, the research on the effect of fluorine on the fetus was carried out. The research is reviewed now.
