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.
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
Maize purple plant pigment protects against fluoride-induced oxidative damage of liver and kidney in rats
Anthocyanins are polyphenols and well known for their biological antioxidative benefits. Maize purple plant pigment (MPPP) extracted and separated from maize purple plant is rich in anthocyanins. In the present study, MPPP was used to alleviate the adverse effects generated by fluoride on liver and kidney in rats. The results
In vivo protective effects of quercetin against sodium fluoride-induced oxidative stress in the hepatic tissue
The protective effects of quercetin against sodium fluoride induced oxidative stress were examined in rat’s liver. Rats were divided into five groups. The first group served as normal group that was treated with standard diet. The second group was intoxicated with sodium fluoride (600 ppm) through drinking water for 1 week. The
[Renal and hepatic changes in albino rats treated with NaF microdose]
The authors, in order to study histologically the effect on the liver and kidneys of salt-fluor, have administred NaF orally to eighty rats, at the dosage of 0.02 mg % per kg of weight. The animals were decapitated on the 180th day of the experiment. The histological test of the kidneys
A fatality due to ingestion of hydrofluoric acid.
We report a fatal case of hydrofluoric acid (HF) ingestion with suicidal intent. Quantitation using an ion-selective electrode for fluoride in fresh bile, gastric contents, kidney, liver, skeletal muscle, urine, and vitreous humor yielded 6.5, 39.0, 10.0, 6.0, 4.5, 5.0, and 4.5 ppm, respectively. In addition to the unfixed specimens,
