Excerpt:
In conclusion, exposure to high fluoride levels [30 & 100 ppm] in drinking water during early stages of life led to increased oxidative stress in the liver of rats as indicated by elevated MDA level and disturbed antioxidant defenses. Adaptive mechanisms in the form of increased activities of GSH-Px and GST operated to combat fluoride induced oxidative stress. But, increased oxidative stress led to depletion of the intrinsic free radical scavengers glutathione and ascorbic acid.

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

Ameliorative effect of tamarind leaf on fluoride-induced metabolic alterations
OBJECTIVES: Fluoride is a serious health hazard across several nations, and chronic intake of fluoride deranges the carbohydrate, lipid and antioxidant metabolism in general. As there are limited remedial measures to prevent fluorosis, we investigated the role of tamarind leaf as a food supplement in restoration of carbohydrate, lipid and

Proposed mechanism for understanding the dose- and time-dependency of the effects of fluoride in the liver.
Fluoride (F) can induce changes in the expression of several liver proteins.It is suggested that these changes are dose- and time-dependent. The objective of this study was to analyze the effect of different F concentrations and exposure times to this ion on the pattern of protein expression in the liver

Effects of melatonin and epiphyseal proteins on fluoride-induced adverse changes in antioxidant status of heart, liver, and kidney of rats
Several experimental and clinical reports indicated the oxidative stress-mediated adverse changes in vital organs of human and animal in fluoride (F) toxicity. Therefore, the present study was undertaken to evaluate the therapeutic effect of buffalo (Bubalus bubalis) epiphyseal (pineal) proteins (BEP) and melatonin (MEL) against F-induced oxidative stress in heart,

Fluoride-induced oxidative stress is involved in the morphological damage and dysfunction of liver in female mice
Fluoride (F), one of the most toxic environmental and industrial pollutants, is known to exert hepatotoxicity. The contribution of oxidative stress to the F tolerance of liver remains largely unknown. In this study, the morphological and ultrastructural characteristics of liver were observed using hematoxylin and eosin staining and transmission electron

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
