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.

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,

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

Co-exposure to non-toxic levels of cadmium and fluoride induces hepatotoxicity in rats via triggering mitochondrial oxidative damage, apoptosis, and NF-kB pathways.
Fluoride (F) and cadmium (Cd) are two common water pollutants. There is low information about their co-exposure in low doses. So, in this study, we evaluated the combination effects of non-toxic doses of F and Cd and the possible mechanism of their combined interaction. Male rats were exposed to non-toxic

The morphological changes and molecular biomarker responses in the liver of fluoride-exposed Bufo gargarizans larvae
Highlights Fluoride triggered marked histological changes in the liver of Bufo gargarizans [the Asiatic toad or Chusan Island toad] Fluoride caused disruption of lipid metabolism. Fluoride resulted in impairing of antioxidant capacity. Fluoride induced alterations of mRNA expression of genes involved in apoptosis. The goal of the current study was to

Apoptotic and Oxidative Mechanisms in Liver and Kidney Tissues of Sheep with Fluorosis.
This study was planned to determine the molecular basis and causes of damage to the kidney and the liver, which are the most affected tissues in sheep exposed to chronic fluoride. For this purpose, liver and kidney tissues were obtained from sheep with signs of fluorosis in the age range

Fluoride content in tea and its relationship with tea quality.
J Agric Food Chem. 2004 Jul 14;52(14):4472-6. Fluoride content in tea and its relationship with tea quality. Lu Y, Guo WF, Yang XQ. Department of Tea Science, Zhejiang University, 268 Kaixuan Road, Hangzhou 310027, People's Republic of China. Abstract: The tea plant is known as a fluorine accumulator. Fluoride (F) content in fresh leaves collected

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
