The oestrone loading test was carried out on fifteen patients suffering from fluorine liver damage. Three pattern curves of the oestrogen fraction (oestrone, 17?-oestradiol and oestriol) excretion in the urine were established. Our data show that there were disturbances in oestrogen metabolism in patients with fluorine liver damage.
Changes in liver antioxidant status of offspring mice induced by maternal fluoride exposure during gestation and lactation
Excessive fluoride intake for a long time has been demonstrated to provoke hepatic oxidative stress in adults. However, the response to fluoride toxicity of liver in newborns exposed to fluoride during embryonic and suckling stages remains unclear. In this study, female Kunming mice were administrated with 25, 50, and 100 mg/L
Effects of sodium fluoride on locomotor behavior and a few biochemical parameters in rats
Spontaneous motor activity and motor coordination were tested in adult female rats after treating with sodium fluoride at 20 or 40 mg/kg dose level daily for 60 days, using an activity chamber and a rota-rod apparatus, respectively. Total protein concentrations were determined in skeletal muscle, liver and serum of similarly
The influence of fluoride on the content of testosterone and cholesterol in rat
Fifty four Wistar male rats were randomly divided into three groups, drinking water containing 0.6 mg/L (control group), 100 mg/L, and 200 mg/L sodium fluoride, respectively. Rats were killed at the second, fourth and sixth weeks after experiment initiation, respectively. The levels of serum testosterone, testis cholesterol, and hepatic tissue
Gluconeogenesis and glycogenolysis in fluoride-treated rats.
Intraperitonial administration of 10 mg fluoride (NaF)/kg body weight resulted in hyperglycemia in rats. Role of gluconeogenesis and glycogenolysis in this hyperglycemic response was evaluated. Results of the study indicate that the fluoride induced hyperglycemia is mainly due to increased hepatic glycogenolysis.
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
