Abstract

The aim of this study was to examine the influence of vitamin E on the liver morphology and carbohydrate enzyme activities of rats intoxicated with sodium fluoride (NaF). Eighteen adult male Wistar rats on a standard rat diet were divided into three equal groups for a five-week experiment: a control group on distilled water; an experimental group I dosed with 4 mg NaF/rat/24hr in the drinking water; and a group II with the same dose of NaF plus 3 mg vitamin E/rat/24hr. Pathomorphological changes in the liver were assessed by paraffin histopathology, and changes in protein content and carbohydrate enzyme activities of aldolase, malate dehydrogenase, lactate dehydrogenase, and sorbitol dehydrogenase were determined by standard methods. Under conditions of this study with rats, supplemental vitamin E partially but did not completely prevent the toxic effects of NaF on the liver histopathology and carbohydrate enzyme activities.

    The present study was undertaken to search out the effect of sodium fluoride, a water pollutant noted throughout the world, including India, on oxidative stress induction in reproductive tissues, sperm pellet, and metabolic tissues like the liver and kidney. The protective effects of testosterone or vitamin-E coadministration were also observed

    BACKGROUND: Fluorine influences many processes occurring in the organism. Controversies over the evaluation of the biological effects of this substance are due to a small difference between tolerable and toxic fluorine doses. One of the main mechanisms of the fluorine toxic action is its ability to induce oxidative stress via

    Fluoride contamination of drinking water can disrupt male gametogenesis and steroidogenesis and induce testicular oxidative stress. Treatment of rats with sodium fluoride at the dose of 20 mg/kg/day for 28 days resulted in significant diminution of testicular Delta5,3beta-hydroxysteroid dehydrogenase (HSD) and 17beta-hydroxysteroid dehydrogenase (HSD) activities and low plasma levels of

  • 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 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

  • Fluoride Exposure Increases Metabolic Requirement for Calcium & Vitamin D

    It is well known that individuals with nutrient deficiencies are more susceptible to fluoride toxicity, including fluoride's bone effects. As discussed in the following studies, fluoride increases the skeleton's need for calcium (and vitamin D) by increasing the amount of unmineralized tissue (osteoid) in the bone. When insufficient calcium and

    A consistent body of animal and human research shows that fluoride exposure worsens the impact of an iodine deficiency. Iodine is the basic building block of the T3 and T4 hormones and thus an adequate iodine intake is essential for the proper functioning of the thyroid gland. When iodine intake is inadequate during infancy and
