Abstract

In the village of Kheru Nayak Thanda in the Gulbarga district of Karnataka, India, 18 children aged 3 to 10 years with endemic skeletal fluorosis were shown to have oxidative stress as evidenced by elevated levels of malondialdehyde in their red blood cells, indicating increased lipid peroxidation. Significant alterations of antioxidant systems in the blood were confirmed by decreased levels of glutathione and uric acid together with an increase in the activity of glutathione peroxidase as well as the level of ascorbic acid along with a slight decrease in the activity of superoxide dismutase.

  • Cytoprotective effects of curcumin on sodium fluoride-induced intoxication in rat erythrocytes

    Curcumin is well known for its potent antioxidant activity. The result of numerous studies showed that antioxidants can protect against fluoride-induced toxicity. In the present study, protective effects of curcumin against sodium fluoride-induced toxicity in rat erythrocytes were evaluated. Curcumin (10 and 20 mg/kg) and vitamin C (10 mg/kg) were

  • In vivo protective effects of gallic acid isolated from peltiphyllum peltatum against sodium fluoride-induced oxidative stress in rat erythrocytes

    Gallic acid has been identified as an antioxidant component of the edible and medicinal plant Peltiphyllum peltatum. The present study examined its potential protective role against sodium fluoride (NaF)-induced oxidative stress in rat erythrocytes. Oxidative stress was induced by NaF administration through drinking water (1030.675 mg m-3 for one week).

    Excerpts: Summary Under the Safe Drinking Water Act, the U.S. Environmental Protection Agency (EPA) is required to establish exposure standards for contaminants in public drinking-water systems that might cause any adverse effects on human health. These standards include the maximum contaminant level goal (MCLG), the maximum contaminant level (MCL), and the secondary

  • Lipid peroxidation and antioxidant enzyme status of adult males with skeletal fluorosis in Andhra Pradesh, India.

    Blood samples from 24 adult males, age 25 to 40, with endemic skeletal fluorosis, living in the Vaillapally village of the Nalgonda district, Andhra Pradesh, India, were examined and compared with samples from 15 matched controls for their antioxidant enzyme activity and lipid peroxidation. Elevated malondialdehyde (MDA) levels indicated an

  • Industrial Fluorosis

    A highly significant relationship of exposure to fluoride was established with the frequency of back and neck surgery, fractures, symptoms of musculoskeletal disease and past history of diseases of bones and joints in the absence of the typical findings of skeletal fluorosis. Monitoring exposed workers for the early manifestations of "musculoskeletal fluorosis" is recommended prior to the development of destructive and degenerative changes of the skeleton.

  • Fluoride & Spinal Stenosis

    Spinal stenosis is a narrowing of the spaces in the spine that results in pressure being placed on the spinal cord and/or nerve roots. Although stenosis can develop without symptoms, it may produce numbness, tingling, pain and difficulty in walking, as well as a heavy/tired feeling in the legs. It is estimated that 250,000 to 500,000 Americans currently have symptoms of spinal stenosis. Skeletal fluorosis is one cause of stenosis.

  • Fluoride & Osteomalacia

    One of fluoride's most well-defined effects on bone tissue is it's ability to increase the osteoid content of bone. Osteoid is unmineralized bone tissue. When bones have too much of it, they become soft and prone to fracture -- a condition known as osteomalacia. As shown below, fluoride has repeatedly been
