Abstract

Fluoride contamination in water (>1.5ppm) is the global problem for health in general. Fluoride has been reported to be a causative factor for male infertility. However, limited scientific literature is available on this aspect. The objective of the present study was to examine the fluoride induced oxidative burden and its association with endogenous and exogenous antioxidant status in seminal plasma of different grade of fluorotic patients (mild, moderate and severe). The lipid peroxide levels and antioxidant status namely superoxide dismutase, catalase, glutathione vitamins (A, C and E) were investigated in seminal plasma. Result of the present study showed that the LPO was found to be gradually increased with severity of the disease. The endogenous and exogenous antioxidants were found to be decreased in severe florotic patients. On the basis of the results it may conclude that fluoride exposure promote oxidative stress and alteration in vitamins in seminal plasma. These alterations may induce pathophysiological activities due to lack of vitamin and antioxidant defense against ROS. However, further in depth studies is required for the understanding of pathophysiology of Fluorosis.

  • Reversal of fluoride induced cell injury through elimination of fluoride and consumption of diet rich in essential nutrients and antioxidants

    The objective of the present communication is to address the issues concerning reversal of fluoride induced cell injury and disease (i.e. fluorosis) through the elimination of fluoride and consumption of a diet containing essential nutrients and antioxidants. Humans afflicted with fluorosis, as a result of consuming fluoride contaminated water or

    In continuing our studies on the effects of fluoride (F) on the toxicity of pesticides, we investigated the interaction of 1 ppm and 10 ppm F in the drinking water of rats orally administered 1 and 10 mg chlorpyriphos/kg bw/day, alone and in combination for 28 days. Changes in antioxidant

  • Antioxidant vitamin and mineral levels in sheep with fluorosis

    The present study was carried out to determine the levels and changes of vitamins A, C, and E, fluoride, and calcium in 30 Morkaraman sheep with fluorosis, comparing them to unexposed healthy controls. The sheep exposed to fluoride showed significant differences in urinary fluoride and the blood levels of beta-carotene

    CONTEXT:  Quercetin is a well known aglycone flavonoid that is widely found in different food sources. OBJECTIVE:  In this study, the in vivo neuroprotective potential of quercetin against sodium fluoride-induced oxidative stress was evaluated. MATERIALS AND METHODS:  Wistar rats were divided into five treatment groups and then subjected to daily

  • 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,

  • Skeletal Fluorosis & Individual Variability

    One of the common fallacies in the research on skeletal fluorosis is the notion that there is a uniform level of fluoride that is safe for everyone in the population. These "safety thresholds" have been expressed in terms of (a) bone fluoride content, (b) daily dose, (c) water fluoride level, (d) urinary fluoride level, and (e) blood fluoride level. The central fallacy with each of these alleged safety thresholds, however, is that they ignore the wide range of individual susceptibility in how people respond to toxic substances, including fluoride.

  • 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

  • Fluoridation, Dialysis & Osteomalacia

    In the 1960s and 1970s, doctors discovered that patients receiving kidney dialysis were accumulating very high levels of fluoride in their bones and blood, and that this exposure was associated with severe forms of osteomalacia, a bone-softening disease that leads to weak bones and often excruciating bone pain. Based on

  • Kidney Patients Are at Increased Risk of Fluoride Poisoning

    It is well established that individuals with kidney disease are susceptible to suffering bone damage and other ill effects from low levels of fluoride exposure. Kidney patients are at elevated risk because when kidneys are damaged they are unable to efficiently excrete fluoride from the body. As a result, kidney patients
