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.

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),

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

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

Fluoride-induced neuronal oxidative stress amelioration by antioxidants in developing rats
Premated 3-month-old albino rats received 200-ppm fluoride ion (F) in their drinking water; the pups born to them were separately administered, in groups of six, daily doses of clinoptilolite, zinc, selenium, vitamin C, vitamin D, and propolis. On post-partum day 45, the pups were sacrificed, brain regions separated, and oxidative

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

Fluoride & Myocardial Damage
Structural damage to the heart resulting from fluoride toxicity has been observed in numerous human and animal studies. The general features of this damage include cloudy swelling, vacuolization or vacuolar degeneration, hemorrhages, interstitial edema, fibrous necrosis, dissolution of nuclei, and thickening of the vessel walls in the heart muscle (Basha

Fluoride & Arterial Calcification
The major change involved with cardiovascular disease is development of atherosclerosis in critical arteries, which is partially characterized by vascular calcification. The level of coronary artery calcification is thought to be the most important indicator of future cardiovascular events. Increased arterial calcifications have frequently been reported in those with skeletal fluorosis

Fluoride, Blood Pressure and Hypertension
Individuals with blood pressure readings that exceed 140/90 are considered hypertensive. Hypertension can increase the risk of stroke, heart attack, heart failure, aortic aneurysms, and peripheral arterial disease. An association between increased fluoride in ground water and increased prevalence of hypertension has been observed, especially among adult males (Amini et

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 & 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
