Abstract
Intravenous infusion of 6 mg of fluoride/kg/hr for 3 hr caused a sharp decrease in formation of respiratory 14CO2 from [14C]glucose, regardless of position of the label. Oxidation of [1-14C]fructose was not impaired, indicating that triose metabolism was not hindered; this information, along with the similarity in depression of metabolism of all labels indicated that glycolysis was not impaired. Glycogen deposition was decreased. The data suggest that the interference caused by fluoride at the observed concentrations is located at or prior to phosphorylation of glucose.

Fluoride in Drinking Water: A Scientific Review of EPA’s Standards.
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

Predominant contribution of the G protein-mediated mechanism to NaF-induced vascular contractions in diabetic rats: association with an increased level of G(qalpha) expression.
The purpose of this study was to determine the mechanism responsible for alterations in NaF-induced contractions of blood vessels from streptozotocin-induced diabetic rats. In the presence of AlCl(3), NaF (>/=7.5 mM) produced significantly greater contractions in diabetic aorta and mesenteric artery compared with age-matched controls. Pretreatment with 1 microM nifedipine

Fluoride toxicity and new-onset diabetes in Finland: a hypothesis
The incidence of type 1 diabetes (T1D) has increased substantially in Finland, but the exact trigger for the onset of T1D is still unknown. We know that use of amoxicillin and anti-cariogenic fluoride tablets is a common practice for children in Finland. It seems that beta-cell destruction is initiated by

Chronic fluorides impact on pancreatic islet cells in workers
Summary: Decreasing of the insulin concentration and increasing of the C-peptide level in blood serum of 72 workers of cryolytes industries detected by radioimmunilogical method. These changes were caused by the fluorine intoxication of workers.

[Activities of some enzymes and concentration of ammonia in serum of rats with fluoride hyperglycemia]
The study was done in 30 one-month-old Wistar FL rats divided into one control and two study groups of ten animals each. Hyperglycemia was induced with sodium fluoride in water at a concentration of 50 or 100 mg/L during four months. Control animals received distilled water. We observed significantly (p

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

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
