    Effects of iron deprivation or chelation on DNA damage in
    experimental colitis.

    Barollo M, D'Inca R, Scarpa M, Medici V, Cardin R, Fries W,
    Angriman I, Sturniolo GC.

    Department of Surgical and Gastroenterological
    Sciences, University of Padua, Via Giustiniani 2,
    Italy, 35128, Padova.

    BACKGROUND AND AIMS. In inflammatory bowel diseases iron
    contributes to the formation of DNA adducts through the
    production of hydroxyl radicals. The aim of our study was to
    evaluate the effects of dietary or pharmacological iron
    deprivation in an experimental model of colitis in the rat
    and its potential protective effect against DNA damage.
    METHODS. Colitis was induced in rats by intracolonic
    instillation of dinitrobenzene sulphonic acid. Rats were
    assigned to an iron-deprived diet or to desferrioxamine
    preceding the induction of colitis. The severity of colitis
    was assessed by the presence of bloody diarrhea, colonic
    macroscopic damage score, body-weight variations and the
    amount of DNA colonic adducts. Hepatic and colonic iron
    concentrations were measured. RESULTS. Treated rats
    experienced less diarrhea and did not lose weight in
    comparison to untreated animals. The macroscopic damage
    score was significantly reduced in the iron-deprived diet
    for the 5-week group ( P=0.03). Liver and colonic iron
    levels were significantly more reduced in the iron-deprived
    groups than in the standard diet group ( P<0.03 and P<0.01
    after a 3- and 5-week iron-deprived diet, respectively). DNA
    adduct formation was significantly reduced in the groups
    deprived of iron for 5 weeks ( P<0.001) or treated with
    desferrioxamine ( P<0.01). CONCLUSIONS. The degree of
    colitis caused by DNBS is macroscopically improved by
    dietary iron deprivation and to a lesser extent by
    pharmacological chelation; genomic damage is reduced by
    dietary iron deprivation or chelation, and this may have
    clinical implications on cancer prevention.

  2. And what exactly are we to make of this, how does it relate
    to any body of theory, to what practical use is it, and
    toward what goal can it be applied? Without this information
    it is but another random abstract plucked from the web, one
    among thousands of such.

    Unless of course if someone shoots some acid up your ass you
    can try this approach.

  4. Aquired iron overload

    Acquired iron overload occurs when one receives
    repeated blood transfusions, is exposed to excessive
    amounts of iron through supplementation, tobacco smoke
    inhalation, alcohol consumption, exposure to some types
    of asbestos, and consumption of an iron-rich diet
    comprised mostly of red meat.

    Secondary iron overload is related to a problem of red blood
    cell production which causes the body to behave as if it
    doesn't have enough iron. Examples of this type of iron
    overload are: thalassemia and sideroblastic anemia.

    Another disorder associated with excess iron is porphyria
    cutanea tarda (PCT) a metabolic problem that is usually
    diagnosed because of blisters and blood spots on the back-
    side of the hands.

    Undiagnosed, untreated iron overload, regardless of its
    origin can lead to diabetes, arthritis, depression,
    impotence, liver-gall bladder disease, complete liver
    failure, heart attack and cancer. Getting the right
    tests, early, is one way to prevent unnecessary organ
    damage and disease.
