Abstract
Summary
Our results suggest that orally administered sodium fluoride enters liver and brain. The blood-brain barrier fails to exclude the fluoride ion from nerve tissue. That fluoride ions also readily pass the placental barrier has been repeatedly demonstrated (9). Fluoride-levels in brain reach a maximum approximately two hours after it has been administered, whereas accumulation in liver continues for at least three hours.

Establishment of drug delivery system nanocapsulated with an antioxidant (+)-catechin hydrate and sodium meta borate chelator against sodium fluoride induced oxidative stress in rats
Oxidative stress a major cause of fluoride induced toxicity and mitochondrial impairment in common in experimental rats during chronic exposure of fluoride. Attempts have been made in the present experiment to diminish oxidative damage, combined therapy with (+)-catechin hydrate (an antioxidant) and sodium meta borate (chelator) were used. Fluoride intoxication

Protective effect of resveratrol on sodium fluoride-induced oxidative stress, hepatotoxicity and neurotoxicity in rats
Protective effect of resveratrol on sodium fluoride-induced oxidative stress, hepatotoxicity and neurotoxicity were studied in rats. A total of 28 Wistar albino male rats were used. Four study groups were randomly formed with seven animals in each. The groups were treated for 21 days with distilled water (control group), with

Tamarind seed coat extract restores fluoride-induced hematological and biochemical alterations in rats.
Fluoride (F-) is becoming an ineluctable environmental pollutant causing deleterious effects in humans. In the present study, we examined whether tamarind seed coat extract (TSCE) is beneficial against the F--induced systemic toxicity and hematological changes. Wistar rats were randomly grouped as follows: group I served as control; group II intoxicated

Protective effects of blackberry and quercetin on sodium fluoride-induced oxidative stress and histological changes in the hepatic, renal, testis and brain tissue of male rat
BACKGROUND: Sodium fluoride (NaF) intoxication is associated with oxidative stress and altered antioxidant defense mechanism. The present study was carried out to evaluate the potential protective role of blackberry and quercetin (Q) against NaF-induced oxidative stress and histological changes in liver, kidney, testis and brain tissues of rats. METHODS: The rats

A fatality due to ingestion of hydrofluoric acid.
We report a fatal case of hydrofluoric acid (HF) ingestion with suicidal intent. Quantitation using an ion-selective electrode for fluoride in fresh bile, gastric contents, kidney, liver, skeletal muscle, urine, and vitreous humor yielded 6.5, 39.0, 10.0, 6.0, 4.5, 5.0, and 4.5 ppm, respectively. In addition to the unfixed specimens,

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.

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
