Abstract
In a new approach to an understanding of the genesis of nonskeletal and skeletal fluorosis, glutathione content in blood was investigated. Thirty cases of fluorosis and forty controls (20 from fluorotic and 20 from nonfluorotic areas) were studied. In fluorotic subjects, blood glutathione concentration was significantly elevated. Urinary hydroxyproline and serum alkaline phosphatase data were also correlated. It appears that the persistent stress of the F- ion demands a protective redox maintainer and that glutatione fulfills that need.

Rutin potentially attenuates fluoride induced oxidative stress mediated cardiotoxicity, blood toxicity and dyslipidemia in rats
The present study was undertaken to evaluate cardio protective effect of rutin against sodium fluoride-induced oxidative stress mediated cardio toxicity and blood toxicity. Cardiac injury was induced by daily administration of sodium fluoride 600ppm in distilled water for 4 weeks. The animals exposed to NaF exhibited a significant increase in

Effect of long term fluoride exposure on lipid composition in rat liver
Chronic fluorosis can severely damage many systems of human body, but its pathogenesis is unclear. Normal composition and structure of cellular membrane lipids are a basic factor to maintain cell function. In this investigation, cellular membrane lipids of the liver were analysed after a long term fluoride treatment for rats

Fluoride increases the susceptibility of developmental dysplasia of the hip via increasing capsular laxity triggered by cell apoptosis and oxidative stress in vivo and in vitro.
Highlights Fluoride does not cause DDH directly but increases its susceptibility by increasing hip capsular laxity. Hip laxity results from apoptosis occurring in capsular fibroblast after fluoride exposure. Fluoride-induced fibroblast apoptosis was triggered by oxidative stress via mitochondrial pathway. The etiology of developmental dysplasia of the hip (DDH) is multifactorial,

Melatonin ameliorates fluoride induced neurotoxicity in young rats: an in vivo evidence
Objective: Developing brain is highly vulnerable to environmental toxins. Recently, fluoride was declared as a developmental neurotoxin and heralded search for natural neuroprotectant. In the present study, we have evaluated the neuroprotective and anti-inflammatory efficacy of melatonin in fluoride induced neurotoxicity. Methods: Animals were divided into following groups; the first group

Effects of Perinatal Fluoride Exposure on Short- and Long-Term Memory, Brain Antioxidant Status, and Glutamate Metabolism of Young Rat Pups.
Exposure to fluoride (F) during the development affects central nervous system of the offspring rats which results in the impairment of cognitive functions. However, the exact mechanisms of F neurotoxicity are not clearly defined. To investigate the effects of perinatal F exposure on memory ability of young rat offspring, dams

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

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,
