Abstract
The impacts of environmental and occupational exposure to ionizing radiation and to long-term intake of high levels of fluoride have caused health problems and increasingly alarming in recent years. Fish oil omega-3 (polyunsaturated fatty acids essential fatty acids) is found in the highest concentrations in fish oil, claim a plethora of health benefits. The objective of the present study was to evaluate the role of fish oil rich in omega-3 fatty acids on sodium fluoride (NaF) and or gamma (?) rays in inducing neurological and biochemical disturbances in rat’s brain cerebral hemispheres. The results revealed that whole body exposure to ?- radiation at 6 Gy applied as fractionated doses (1.5 Gy x 4 times) and/or chronic receipt of NaF solution (0.13 mg/Kg/day) for a period of 28 days, significantly increased brain fluoride and calcium content, decreased level of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) and induced brain oxidative stress which led to neurotransmitters dysfunction.
Supplementation of treated rats with fish oil, via gavages, at a dose of 400 mg/kg body wt has significantly modulated oxidative stress and neurotransmitters alterations. It could be concluded that EPA and DHA, found in fish oil, could possibly protect brain from damaging free radicals and consequently minimize the severity of brain biochemical disturbances

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

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

Neuroprotective activity of Matricaria recutita against fluoride-induced stress in rats.
CONTEXT: Oxidative stress plays a key role in pathophysiology of many neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and so on. Although Matricaria recutita L. (Asteraceae), German chamomile, is traditionally used for central nervous system (CNS)-related diseases, its antistress properties have received little attention. OBJECTIVE: The present study evaluated the

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

Reversal of fluoride induced cell injury through elimination of fluoride and consumption of diet rich in essential nutrients and antioxidants
The objective of the present communication is to address the issues concerning reversal of fluoride induced cell injury and disease (i.e. fluorosis) through the elimination of fluoride and consumption of a diet containing essential nutrients and antioxidants. Humans afflicted with fluorosis, as a result of consuming fluoride contaminated water or

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 & Oxidative Stress
A vast body of research demonstrates that fluoride exposure increases oxidative stress. Based on this research, it is believed that fluoride-induced oxidative stress is a key mechanism underlying the various toxic effects associated with fluoride exposure. It is also well established that fluoride's toxic effects can be ameliorated by exposure

Factors which increase the risk for skeletal fluorosis
The risk for developing skeletal fluorosis, and the course the disease will take, is not solely dependent on the dose of fluoride ingested. Indeed, people exposed to similar doses of fluoride may experience markedly different effects. While the wide range in individual response to fluoride is not yet fully understood, the following are some of the factors that are believed to play a role.
