Abstract
Radish (Raphunus sativa), coriander (Coriandrum sativum), mustard (Brassica juncea), and spinach (Spinacea oleracea) plants were grown in earthen pots watered with aqueous solutions containing 0, 5, and 10 mg F/L. Fluoride (F) uptake and superoxide dismutase (SOD) activity (unit/mg protein/min) were estimated from the edible plant parts following harvest after 60 days. The values of
both entities rose with increasing F exposure in the order radish > coriander > spinach > mustard. The results indicate that plant species tolerant to F toxicity induce higher antioxidant SOD activity, which may be an adaptive reaction in plant cells to attenuate the damaging effect of reactive oxygen species (ROS) generated during F stress.

Sodium fluoride activates ERK and JNK via induction of oxidative stress to promote apoptosis and impairs ovarian function in rats
The toxicity of sodium fluoride (NaF) to female fertility is currently recognized; however, the mechanisms are unclear. Previously, we reported a reduction in successful pregnancy rates, ovarian atrophy and dysfunction following exposure to NaF. The purpose of this study was to elucidate the underlying molecular mechanisms. Female Sprague-Dawley rats (10

Oxidative burden and altered trace elements as a biomarker of excessive endemic fluoride exposure in school children of eastern region in Rajasthan India
Fluoride Toxicity due to the presence of higher levels of fluoride in drinking water (>1.5ppm) may be serious problems in health of the children and adult in general. In the state of Rajasthan, almost all districts have high Fluoride (up to 18.0 ppm) in their drinking / ground water sources

Myeloperoxidase activity and its corresponding mRNA expression as well as gene polymorphism in the population living in the coal-burning endemic fluorosis area in Guizhou of China
The myeloperoxidase (MPO) activity and its corresponding mRNA expression as well as gene polymorphism were investigated in the population who live in the endemic fluorosis area. In the study, 150 people were selected from the coal-burning endemic fluorosis area and 150 normal persons from the non-fluorosis area in Guizhou province

N-acetylcysteine protects against fluoride-induced oxidative damage in primary rat hepatocytes
Fluoride induces the overproduction of free radicals, which might in turn affect various biochemical parameters. Therefore, the aim of this study was to elucidate the role of N-acetylcysteine (NAC) in decreasing fluoride-induced oxidative stress. The fluoride intoxicated (0.002; 0.082; 0.164mmol/l) rat hepatocytes was pre-treated (60min) and simultaneously treated with NAC

Relationship between intracellular Ca²+ and ROS during fluoride-induced injury in SH-SY5Y cells.
The mechanisms underlying the neurotoxicology of endemic fluorosis still remain obscure. To explore lactate dehydrogenase (LDH) leakage, intracellular Ca²? concentration ([Ca²?]i ) and reactive oxygen species (ROS) production induced by fluoride, human neuroblastoma (SH-SY5Y) cells were incubated with sodium fluoride (NaF, 20, 40, 80 mg/L) for 24 h, with 40

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
