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.

    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

    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

  • Fluoride Is Not an Essential Nutrient

    In the 1950s, dentists believed that fluoride was a “nutrient.” A nutrient is a vitamin or mineral that is necessary for good health. Dentists believed that fluoride ingestion during childhood was necessary for strong, healthy teeth. A “fluoride deficiency” was thus believed to cause cavities, just like a deficiency of calcium can

  • 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,

    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 & 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
