Forty-five male patients suffering from chronic fluorine poisoning and fifteen normal men were investigated. The urinary excretion of oestrone, oestradiol-17?, oestriol and 16-epioestriol was studied. The results revealed a high content of oestrogens in urine. This is explained by a metabolic disorder in the liver.
DNA damage, apoptosis and cell cycle changes induced by fluoride in rat oral mucosal cells and hepatocytes
AIM: To study the effect of fluoride on oxidative stress, DNA damage and apoptosis as well as cell cycle of rat oral mucosal cells and hepatocytes. METHODS: Ten male SD rats weighing 80-120 g were randomly divided into control group and fluoride group, 5 animals each group. The animals in
Lipid peroxidation and antioxidant defense systems in liver of rats in chronic fluoride toxicity
In conclusion, exposure to high fluoride levels [30 & 100 ppm] in drinking water during early stages of life led to increased oxidative stress in the liver of rats as indicated by elevated MDA level and disturbed antioxidant defenses. Adaptive mechanisms in the form of increased activities of GSH-Px and
Isolated and combined activity of low concentrations of hydrogen fluoride and sulfur dioxide in a chronic experiment.
Exposure of rats to the combined effect of HF and SO2 decreased body weight, O2 consumption and myoglobin levels in muscles and increased the erythrocyte level in blood. Low and high concentrations of HF and SO2 decreased cytochrome oxidase activity in almost all organs and had a toxic effect on
Fatal cases of acute suicidal sodium and accidental zinc fluorosilicate poisoning. Review of acute intoxications due to fluoride compounds.
Fluoride, of all inorganic substances, is among the least likely to be identified by a routine toxicological analysis. Acute poisonings with salts of hydrofluoric or fluorosilicic acid, however, although relatively uncommon, may occur. Some fluorosilicates, salts of fluorosilicic acid (e.g. Al, Zn, Pb, Mg) are used as stone consolidants, others
Kenetics of fluoride penetration in liver and brain.
Summary Our results suggest that orally administered sodium fluoride enters liver and brain. The blood-brain barrier fails to exclude the fluoride ion from nerve tissue. That fluoride ions also readily pass the placental barrier has been repeatedly demonstrated (9). Fluoride-levels in brain reach a maximum approximately two hours after it has
