Abstract

Evidence from other forms demonstrating mitotic chromosome damage has suggested that sodium fluoride (NaF), a primary air pollutant, be explored as a mutagenic compound in female mammalian germ cells. In vitro experiments with mouse, sheep, and cow oocytes have disclosed a low incidence of anaphase lags, suppression of polar body I, and fragmentation and rearrangement. In vivo experiments showed only a minor effect on oocyte meiotic maturation, but species’ variations of sensitivity to NaF would suggest further investigations of progeny of the ewe and cow in contaminated areas.

    1) The low incidence of dental caries observed in mongoloid patients led to an investigation of the role of fluorine in this condition. 2) A statistical study of the geographical distribution of mongolism in Wisconsin, Illinois, Idaho, North and South Dakota (U.S.A.) shows a parallelism between the prevalence of this condition

  • Sodium fluoride disrupts DNA methylation of H19 and Peg3 imprinted genes during the early development of mouse embryo

    Sodium fluoride (NaF) is associated with embryonic and fetal development abnormalities, but the mechanism by which this occurs is unclear. DNA methylation, an important epigenetic reprogramming mechanism, is essential for normal embryonic development. Thus, we investigated the effect of NaF on DNA methylation in early mouse embryos, as well as

    A new statistical study on the distribution of mongolism in cities in Illinois, United States, from January 1, 1950 to December 31, 1956, permits us to verify an increasing frequency of this affliction associated with the concentration of fluorine in the drinking water. This study follows a preceding inquiry on the

    The human placenta does not prevent the passage of fluoride from a pregnant mother's bloodstream to the fetus. As a result, a fetus can be harmed by fluoride ingested pregnancy. Based on research from China, the fetal brain is one of the organs susceptible to fluoride poisoning. As highlighted by the excerpts
