  • Effects of fluoride and mercury on human cytokine response in vitro

    RATIONALE: Over the past 50 years individuals in westernized societies have been increasingly exposed to mercury (e.g. through contaminated fish and dental amalgam) and fluoride (e.g. through drinking water, toothpaste and gels). Given the increasing incidence of allergic diseases and the known immunomodulatory effects of these agents, we investigated their

  • Bronchial responsiveness, eosinophilia, and short term exposure to air pollution

    The number of capillary blood eosinophils and the prevalence of bronchial hyperresponsiveness (BHR) were compared between schoolchildren living in a polluted area (Ardal) and unpolluted area (Laerdal). In Ardal there is an aluminium smelter emitting sulphur dioxide and fluoride to the environment. Daily measurements of these pollutants in ambient air

  • Histaminergic mediation of the response of rat skin to topical fluorides

    The topical application of sodium fluoride to abraded rat skin produced several morphological and biochemical effects. Related to the degranulation of dermal mast cells, skin histamine concentration was increased, fluorides were absorbed into the skin, and deposited mainly kin mitochondria. Dermal histamine binding was decreased for both H1 and H2

  • Suppression of pulmonary antibacterial defenses mechanisms and lung damage in mice exposed to fluoride aerosol

    In endemic fluorosis areas in China associated with coal burning, indoor airborne fluoride pollution is severe. To determine the effects of fluoride aerosols on pulmonary antibacterial defense mechanisms and lung damage, mice were exposed to various concentrations of fluoride aerosol (2, 5, or 10 mg/m3) or filtered air (control) for

  • Allergy and hypersensitivity to fluoride

    A review of the literature was undertaken in response to four recent reviews which found that the evidence that fluoride was an allergen was unconvincing. Reports were found of urticaria, contact dermatitis and stomatitis occurring in response to fluoride, settling on the withdrawal of fluoride and recurring with appropriate challenges.

  • Is the Ingestion of Fluoride an Immunosuppressive Practice?

    This paper records several observations which suggest that habitual ingestion of small doses of fluoride, even as small as the 1 mg/L contained in fluoridated water, may decrease the function of the immune system.

  • Does Fluoride Ingestion Affect Developing Immune System Cells?

    Considerations, supported by some published experimental evidence, suggest that fluoride released during the resorption of high-fluoride bone may produce detrimental effects not only on bone cells but on developing cells of the immune system.

  • Fluoride & the Immune System - Summation from the US National Research Council (2006)

    “There is no question that fluoride can affect the cells involved in providing immune responses. The question is what proportion, if any, of the population consuming drinking water containing fluoride at 4.0 mg/L on a regular basis will have their immune systems compromised? Not a single epidemiologic study has investigated whether fluoride in the drinking water at 4 mg/L is associated with changes in immune function. Nor has any study examined whether a person with an immunodeficiency disease can tolerate fluoride ingestion from drinking water.”
