  • [Effects of selenium on the damage of learning-memory ability of mice induced by fluoride].

    Sodium fluoride added with or without selenite in deionized water was administered to male mice for 8 weeks. The influences of fluoride on learning-memory behavior were tested on Y-maze, and the ultrastructure of Gray 1 synaptic interface in the CA3 area hippocampus was qualitatively analyzed by electron microscopy and computer

    [Objective] To investigate the effect of iodine and selenium on learning memory behavior impairment induced by fluorosis and blood biochemical criterion change of rats. To study the antagonism of iodine and selenium on fluorosis. [Methods] After the rats with fluorosis drinking water with different concentrations of iodine ( I)

  • Research on the effects of fluoride on child intellectual development under different environments

    Goal:  To study the effects of the fluoride and iodine content of drinking water on child intellectual development and the interaction between the two factors and also the relationship of educational factors to such development. Methods: The subjects of the investigation were 8- to 14-year-old children randomly selected from endemic areas as well

  • [Effects of high fluoride and low Iodine on learning-memory and TchE of brain in offspring rats].

    Objective To study the effect of high level fluoride and low level iodine on learning-memory in offspring rats and possible mechanism. Methods Thirty-two Wistar rats were randomly divided into four groups each of eight (female:male=(3:1).) The rats were treated with high fluoride (100 and 150 mg NaF/L), low iodine (0.0855 mg/kg),

  • The effect of fluorine on the level of intelligence in children.

    Recently, many researchers and scholars have studied about the effects of the trace element, iodine, on the level of intelligence in children. However there has been little coverage or noise about the same effect of fluorine on children. For this purpose we have performed some research and the results are as follows.

  • Fluoride: Developmental Neurotoxicity.

    Developmental Neurotoxicity There has been a tremendous amount of research done on the association of exposure to fluoride with developmental neurotoxicity. There are over 60 studies reporting reduced IQ in children and several on the impaired learning/memory in animals. And there are studies which link fluoride to Attention Deficit Hyperactivity Disorder. Teaching

    As of February 2021, a total of 76 studies have investigated the relationship between fluoride and human intelligence. Of these investigations, 68 studies have found that elevated fluoride exposure is associated with reduced IQ in humans, while over 60 animal studies have found that fluoride exposure impairs the learning and/or

  • Nutrient Deficiencies Enhance Fluoride Toxicity

    It has been known since the 1930s that poor nutrition enhances the toxicity of fluoride. As discussed below, nutrient deficiencies have been specifically linked to increased susceptibility to fluoride-induced tooth damage (dental fluorosis), bone damage (osteomalacia), neurotoxicity (reduced intelligence), and mutagenicity. The nutrients of primary importance appear to be calcium,

  • Fluoride Exposure Increases Metabolic Requirement for Calcium & Vitamin D

    It is well known that individuals with nutrient deficiencies are more susceptible to fluoride toxicity, including fluoride's bone effects. As discussed in the following studies, fluoride increases the skeleton's need for calcium (and vitamin D) by increasing the amount of unmineralized tissue (osteoid) in the bone. When insufficient calcium and
