Abstract
The CSF fluoride level of individuals drinking water with normal fluoride content and of patients with endemic fluorosis were studied. For the purpose of studying the relationship between the dynamic equilibrium of the CSF fluoride and other body fluids, urine and blood fluoride were examined simultaneously. Fluoride was revealed in every CSF sample of the control group and its mean value was lower than that of the blood. The CSF fluoride concentration of patients with fluorosis was slightly higher than that of the control group, although there was no statistically significant difference. The results suggests that fluoride is a normal component of CSF. In severe cases of fluorosis or breakdown of the blood-brain in some diseases of the central nervous system, the CSF fluoride value might be increased.

The tissue distribution of fluoride in a fatal case of self-poisoning.
The purpose of this paper is to report a case of fluoride poisoning along with a discussion of poisoning characteristics, analytical procedures, and a review of previous reports of fatal intoxications with analytical data. A case of suicidal ingestion of 40 mL of a rust removal agent containing hydrofluoric acid

[Influence of free radical inducer on the level of oxidative stress in brain of rats with fluorosis].
OBJECTIVE: To study changes in content of lipid peroxide and composition of fatty acids in the brain of rats affiliated with chronic fluorosis after treatment with free radical inducer (ferric ion). METHODS: Thirty-six Wistar rats were divided into three groups, fed with similar fodder and varied concentrations of fluoride in drinking

Environmental and physiological factors affecting dental fluorosis
In addition to differences in fluoride intake and possibly to calcium deficiency or malnutrition, there are several factors which may account for individual differences in the occurrence of dental fluorosis. Disorders in acid-base balance affect the renal handling of fluoride such that, in acidosis, the excretion rate is diminished and,

Brain lipid peroxidation and antioxidant systems of young rats in chronic fluoride intoxication
A study was made of the effect of fluoride on oxidative stress in rats during their early stages in life. Wistar albino rats were exposed to 30 ppm and 100 ppm fluoride (from sodium fluoride) in drinking water during the last one week of intrauterine life and then up to

Effects of drinking water fluorosis on L-type calcium channel of hippocampal neurons in mice.
Highlights Fluoride affects calcium metabolism in mice. Fluoride significantly increases the current peak of the LTCCs. Fluoride reduces the activation voltage of LTCCs. Fluoride delays the inactivation or deactivation of LTCCs. The study aimed to investigate the effects of drinking water fluorosis on L-type calcium channels (LTCCs) in mouse hippocampal neurons.

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 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

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
