Abstract
To investigate effects of sodium fluoride (NaF) on the cerebellum cerebral hemisphere brain of rats and its possible amelioration by the popular Ayurvedic herbal health product triphala, adult female Wistar rats (Rattus novergicus) were administered 10 mg NaF/kg bw/day and 30 mg triphala/kg bw/day for 30 days. A significant decline in body and brain tissue weights after NaF treatment was noted. The decreased succinate dehydrogenase (SDH) activity indicated an alteration in mitochondrial structure and function by fluoride poisoning affecting energy metabolism. An increase in the total lipid could be the result of the inhibition of enzymes and reduction of fatty acid synthesis. Moreover, increased lipid peroxidation indicated an oxidative stress in the brain. These effects were correlated with histological changes and accumulation of fluoride in the neural tissue. However, these changes were ameliorated by co-supplementation of triphala with NaF. The antioxidant properties of the herbal product triphala therefore had an alleviating effect on NaF-induced neurotoxicity in rats.

Neuroprotective effects of methyl-3-O-methyl gallate against sodium fluoride-induced oxidative stress in the brain of rats
Methyl-3-O-methyl gallate (M3OMG) is a rare natural product that showed promising in vitro antioxidant activities. In this study, the protective role of synthetic M3OMG against sodium fluoride (NaF)-induced oxidative stress in rat brain was evaluated. Animals were treated with either M3OMG (10 and 20 mg/kg i.p.), vitamin C (10 mg/kg

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

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

Ameliorative effects of oleanolic acid on fluoride induced metabolic and oxidative dysfunctions in rat brain: experimental and biochemical studies
Beneficial effects of oleanolic acid on fluoride-induced oxidative stress and certain metabolic dysfunctions were studied in four regions of rat brain. Male Wistar rats were treated with sodium fluoride at a dose of 20 mg/kg b.w./day (orally) for 30 days . Results indicate marked reduction in acidic, basic and neutral

Evaluation of standardized Bacopa monniera extract in sodium fluoride-induced behavioural, biochemical, and histopathological alterations in mice
Effect of standardized Bacopa monniera (BM; family: Scrophulariaceae) extract (100 and 300 mg/kg) against sodium fluoride (NaF; 100 and 200 ppm)-induced behavioural, biochemical, and neuropathological alterations in mice was evaluated. Akinesia, rotarod (motor coordination), forced swim test (depression), open field test (anxiety), transfer latency (memory), cholinesterase (ChE), and oxidative stress

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

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 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
