Abstract

The aim of this study was to determine if streptozotocin-induced diabetes in rats as a model for Type-1 human diabetes causes changes in the levels of fluoride (F) and biogenic elements in the bones and serum in the initial stage of the disease. Twenty-two female Wistar rats were given streptozotocin to induce diabetes; after 10 days the femoral bones and blood were collected for determination of F by potentiometric analysis, Ca and Mg by atomic absorption spectrometry, and estradiol by electroluminescence. At various levels of significance, F, Ca, and Mg increased in the bones. In the serum, F decreased, but Ca, Mg, and estradiol increased. The results indicate that diabetes in the early stages affects uptake of F, Ca, and Mg intake into the bones, which may result in defective crystal formation and an increase of amorphous mineral structure in the bone.

    With the recognition of their ability to promote weight loss, conjugated dienes of linoleic acid (CLA) have become the main ingredient of certain dietary supplements to counteract obesity. The results of prospective studies, however, indicate there may be long-term side effects that could be of key importance for the safety

    The LD50 for fluoride was elevated from less than 60 mg F/kg body weight to 172 mg F/kg when magnesium (as MgCl2), equivalent to 3 times that of F, was administered by gavage 30 min after the F dose. A dose of 30 mg F/kg elevated the mean steady state

    INTRODUCTION: Trace elements are known to influence bone metabolism; however, their effects may be exacerbated in renal failure because dialysis patients are unable to excrete excess elements properly. Our study correlated bone quality in dialysis patients with levels of bone fluoride, magnesium, and aluminum. A number of studies have linked

  • Fluoride & Impaired Glucose Tolerance

    The proper regulation of blood glucose levels is essential to good health. When the body's ability to regulate blood glucose levels falters, as occurs in diabetes mellitus, chronic elevated glucose levels (hyperglycemia) can lead to serious complications. These consequences include damage to the kidneys, nervous system, cardiovascular system, retina, legs

  • Fluoride & Insulin

    Insulin is a hormone produced by the pancreas that is responsible for maintaining appropriate levels of glucose in the blood. Insulin allows the body’s cells to take up glucose from the blood, and either use it as an energy source or store it as glycogen. Blood glucose levels in diabetics

  • "Pre-Skeletal" Fluorosis

    As demonstrated by the studies below, skeletal fluorosis may produce adverse symptoms, including arthritic pains, clinical osteoarthritis, gastrointestinal disturbances, and bone fragility, before the classic bone change of fluorosis (i.e., osteosclerosis in the spine and pelvis) is detectable by x-ray. Relying on x-rays, therefore, to diagnosis skeletal fluorosis will invariably fail to protect those individuals who are suffering from the pre-skeletal phase of the disease. Moreover, some individuals with clinical skeletal fluorosis will not develop an increase in bone density, let alone osteosclerosis, of the spine. Thus, relying on unusual increases in spinal bone density will under-detect the rate of skeletal fluoride poisoning in a population.
