Abstract
The effect of fluoride (F) and supplementary vitamins and minerals on lipid peroxidation (LPO) and redox state (RS) in heart , kidney and liver of 40 (4 groups of 10) male Wistar rats were studied. One group of rats was left untreated as control, group 1 was received 5 mg/l NaF in their drinking water, group 2 was received 5 mg/l NaF in their drinking water plus vitamins (A, C, and D) in their diet, and group 3 was received 5 mg/l NaF in their drinking water plus vitamins (A, C, and D) and minerals (Mg-, Mn-, Zn-sulfate, and Na-citrate) in their diet. In comparison with the group 2, 3 and controls, elevated malondialdehyde (MDA) content in the group 1 indicated an increase in LPO product. In addition, unsteady ratios of oxidized to reduced nicotinamide adenine dinucleotide (NAD+/NADH) reflected significant alterations in the RS status. These results demonstrate that the combination of vitamins and minerals supplementation proved to restore MDA content and establish steady RS status that has not been previously reported.

Protective effects of vitamin C against fluoride toxicity.
Fluorine is a highly toxic substance that is widely distributed with drinking water and nutrients. While fluorine is not free in nature, it can form compounds with almost all metals and nonmetals except oxygen and inert gases. Fluorine is found in the environment in water, soil, air, nutrients, and vegetation

The effect of high fluoride intake on tissue trace elements and histology of testicular tubules in the rat
1. Male Wistar rats were exposed to fluoride (F) at concentrations of 100- and 200 ppm in their drinking water for 6- and 16 weeks. 2. The high F intake caused several-fold increase in the F concentrations in the testes and bone as compared with control rats, both after the

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

Amelioration of fluoride toxicity by vitamins and calcium on reproductive organs of female rat
Normal female rats of Wistar strain (Rattus norvegicus) weighing between 150–200 g were treated with fluoride (Fl) contaminated drinking water (FW, 5.8 ppm), vitamin C (6 mg) and vitamin C (6 mg) + D (6 mg once a week) + calcium (6 mg) for 30 days. Fl water treatment to

Fetotoxicity of fluoride in rats and the protective action of some antioxidants
The aim of this study was to assess the efficacy of antioxidants to prevent or alleviate fluoride (F) toxicity in pregnant female Wistar rats and their fetuses. Groups of pregnant rats (10 in each group) were treated by oral intubation with F (40 mg F – /kg bw/day from NaF),

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

Fluoride Exposure Increases Metabolic Requirement for Magnesium
Fluoride's toxicity is significantly enhanced in the presence of nutritional deficiencies. Similarly, fluoride exposure increases the body's requirement for certain nutrients. An individual with a high intake of fluoride, for example, will need a proportional increase in calcium to avoid the mineralization defects (e.g., osteomalacia) that fluoride causes to bone

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 & Arteriosclerosis
Healthy arteries are flexible and elastic, allowing efficient transfer of blood and nutrients from the heart to the rest of the body. Arteriosclerosis refers to a stiffening of the arteries, including loss of elasticity. This is a slow, progressive disease that may begin early in life from damage to the

Fluoride & Electrocardiogram Abnormalities
An electrocardiogram (ECG) is a diagnostic test that measures the electrical activity of the heart. An ECG can reveal heart rate, heart rhythym (i.e. steady or irregular), and the strength and timing of the heart’s natural electrical signals. ECGs are described in terms of “waves” (e.g. amplitude and duration). Problems
