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,

  • Effect of NaF on albino female mice with special reference to behavioral studies and ACh and AChE levels

    The present study investigates the effect of the Sodium Fluoride (NaF) on Wistar Albino mice. The animals have been divided into three batches each containing five individuals among which 1 batch served as control while, remaining two batches were treated with 5 and 10ppm respectively. After completion of exposure, the

    This study reports the protective effects of tamarind ingestion against fluoride induced changes on motor activity and metabolism of Gastrocnemius muscle (GM) of rats. The male Wistar rats were divided into four groups - control, fluoride treated i.p. (20 mg NaF/Kg bw) and Tamarind (Tamarindus indicus III -150mg/kg bw and

  • Neurofunctional effects of developmental sodium fluoride exposure in rats.

    Contrasting studies on the toxic effects of sodium fluoride (NaF) during developmental stages of Wistar rats, lead us to investigate the neurofunctional effects caused by its perinatal exposure, devoid of any overt sign of toxicity and/or gross malformation. NaF solution was administered to pregnant rats by intragastric gavage at a

  • 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

    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

    The possibility that fluoride ingestion may impair intelligence and other indices of neurological function is supported by a vast body of animal research, including over 40 studies that have investigated fluoride's effects on brain quality in animals. As discussed by the National Research Council, the studies have consistently demonstrated that fluoride, at widely varying concentrations, is toxic to the brain.
