Abstract
Premated 3-month-old albino rats received 200-ppm fluoride ion (F) in their drinking water; the pups born to them were separately administered, in groups of six, daily doses of clinoptilolite, zinc, selenium, vitamin C, vitamin D, and propolis. On post-partum day 45, the pups were sacrificed, brain regions separated, and oxidative stress markers were analyzed. Prenatal (maternal) and postnatal F exposure in the developing rats caused a significant increase in the activity of lipid peroxidation and a decrease in catalase, superoxide dismutase, and glutathione peroxidase activity, thus indicating vulnerability of the developing brain to oxidative stress. Alterations were region specific, and oral supplementation of the listed antioxidants not only inhibited oxidative stress but also enhanced the activity of antioxidant enzymes. Administration of antioxidants during F exposure significantly overcame neuronal F toxicity (mostly with p<0.05 or <0.01) and therefore may be a therapeutic strategy for fluorotic victims.

Protective effects of curcumin against fluoride-induced oxidative stress in the rat brain
We examined effects of a plant polyphenolic compound, curcumin, against fluoride-induced oxidative stress in the rat brain. Five experimental groups of male rats (10 animals each) were compared. Animals of these experimental groups were treated with curcumin (10 and 20 mg/kg body mass), vitamin C (10 mg/kg), and sample solvent

Antioxidants in the management of fluoride induced neural oxidative stress in developing rats
Fluoride (F) is highly electronegative anion with cumulative toxic effects, from prolonged ingestion that can lead to the pathogenesis known as fluorosis, a condition especially persistent in third world countries, where populations have little choice as to the main source of F-contaminated drinking. In recent times many neurological problems among

Protective role of gallic acid on sodium fluoride induced oxidative stress in rat brain
Gallic acid is known as a potent antioxidant active compound of the edible and medicinal plant Peltiphyllum peltatum. The main objective of this study was to evaluate the neuroprotective effects of gallic acid against sodium fluoride induced oxidative stress in rat brain. Gallic acid (10 and 20 mg/kg) and vitamin C

Mitigating role of quercetin against sodium fluoride-induced oxidative stress in the rat brain
CONTEXT: Quercetin is a well known aglycone flavonoid that is widely found in different food sources. OBJECTIVE: In this study, the in vivo neuroprotective potential of quercetin against sodium fluoride-induced oxidative stress was evaluated. MATERIALS AND METHODS: Wistar rats were divided into five treatment groups and then subjected to daily

Neuroprotective effect of ascorbic acid and ginkgo biloba against fluoride caused neurotoxicity
Excessive consumption of fluoride through drinking water or other sources lead to skeletal and dental fluorosis. According to the world health organization 23 nations are facing the problem of fluorosis. In the recent past researchers describe the non-skeletal fluorosis where soft tissues and major organs are the victims of fluoride

Nutrient Deficiencies Enhance Fluoride Toxicity
It has been known since the 1930s that poor nutrition enhances the toxicity of fluoride. As discussed below, nutrient deficiencies have been specifically linked to increased susceptibility to fluoride-induced tooth damage (dental fluorosis), bone damage (osteomalacia), neurotoxicity (reduced intelligence), and mutagenicity. The nutrients of primary importance appear to be calcium,

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 78 studies reporting reduced IQ (75 studies with children and 3 studies with adults) and several on the impaired learning/memory in animals. And there are studies which link

Skeletal Fluorosis & Individual Variability
One of the common fallacies in the research on skeletal fluorosis is the notion that there is a uniform level of fluoride that is safe for everyone in the population. These "safety thresholds" have been expressed in terms of (a) bone fluoride content, (b) daily dose, (c) water fluoride level, (d) urinary fluoride level, and (e) blood fluoride level. The central fallacy with each of these alleged safety thresholds, however, is that they ignore the wide range of individual susceptibility in how people respond to toxic substances, including fluoride.
