Abstract

Rats given sodium fluoride at 10 mg/kg daily by the intraperitoneal route were more sensitive to the convulsant action of strychnine and pentylenetetrazol and to electroshock. This increase in sensitivity to CNS stimulation was observed also in two other groups of rats which were given a diet with added sodium fluoride amounting to 7 and 70 parts per million in terms of fluoride. Prolonged treatment with fluoride also lengthened the sleeping time induced by pentobarbital and increased the protective effect of diphenylhydantoin against electroshock. The increase in sensitivity to some CNS-active agents in the fluoride-treated rats disappeared after these rats were given the control diet for 2 weeks,

  • Histological effects of fluoride on cerebrum of adult albino rats.

    The pilot study was conducted on 10 adult albino rats of either sex 150 - 200gm each. Two equal groups of control and experimental was made. The control group received food and water ad libitum whereas experimental group received 30 ppm of NaF for 8 weeks. The macroscopic features like

  • Effects of sodium fluoride on locomotor behavior and a few biochemical parameters in rats

    Spontaneous motor activity and motor coordination were tested in adult female rats after treating with sodium fluoride at 20 or 40 mg/kg dose level daily for 60 days, using an activity chamber and a rota-rod apparatus, respectively. Total protein concentrations were determined in skeletal muscle, liver and serum of similarly

  • Neurobehavioral toxicity produced by sodium fluoride in drinking water of laboratory rats

    The effect of exposure to different concentrations of sodium fluoride (Na-F) for different durations on learning and memory tasks in rats (non-associative and associative learning) was assessed in our study. Three groups of fifteen pregnant Wistar female rats each, were administered Na-F in drinking water at one of three concentrations;

    The present work evaluated the neuroprotective functions of Ginkgo biloba extract (GBE) on cognitive and behavioural functions in fluoride intoxicated rats. Thirty male Wistar rats were randomly divided into 5 Groups (n=6 in each Group). Group 1 was Control that received water, Groups 2 to 5 were treated with 100

    Disturbances caused by excess or shortages of certain elements can affect the cerebral reward system and may therefore modulate the processes associated with the development of dependence as was confirmed by behavioural studies on animals addicted to morphine. Earlier publications demonstrated and proved the neurodegenerative properties of both low and

  • Fluoride's Effect on Fetal Brain

    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

  • 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

  • Fluoride & IQ: 67 Studies

    As of May 2020, a total of 75 studies have investigated the relationship between fluoride and human intelligence. Of these investigations, 67 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

  • Fluoride Affects Learning & Memory in Animals

    An association between elevated fluoride exposure and reduced intelligence has now been observed in 65 IQ studies. Although a link between fluoride and intelligence might initially seem surprising or random, it is actually consistent with a large body of animal research. This animal research includes the following 45 studies (out
