Abstract

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 ppm of sodium fluoride for 30 days while the Groups 3, 4, and 5 were drug treated at 50 mg/kg 100 mg/kg and 200 mg/kg body weight of GBE for 15 days. After 45 days of treatment protocol various behavioural tests (Spatial learning (Y maze, T maze and Passive avoidance test) performed. The data were compared between the groups. The fluoride administered rats that received the only fluoride showed significant impairment in spatial learning and memory as assessed by behavioural tests; the GBE treated animals showed significantly improved learning and memory in a dose-dependent manner. The present study concludes the dose-dependent protective role of GBE in sodium fluoride toxicity induced learning and memory deficits.

  • 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

    Neurodevelopmental disabilities, including autism, attention-deficit hyperactivity disorder, dyslexia, and other cognitive impairments, affect millions of children worldwide, and some diagnoses seem to be increasing in frequency. Industrial chemicals that injure the developing brain are among the known causes for this rise in prevalence. In 2006, we did a systematic review

  • Fluoride's Direct Effects on Brain: Animal Studies

    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.

    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

    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.
