Eight 14-week-old male Wistar FL strain rats were administered sodium fluoride in a single intraperitoneal dose (35 mg NaF/kg of bw). After 90 min the rats were fatally anesthetized with ether, and blood samples were taken. Compared to ten control rats, fluoride-treated rats developed hyperglycemia accompanied by a statistically significant increase in the concentration of fluoride, creatinine, and urea and a decrease in the level of protein and calcium in the blood serum. The results indicate disturbances in the filtrating function of kidneys in rats.
Serum ionic fluoride concentrations are related to renal function and menopause status but not to age in a Japanese general population
BACKGROUND: There have been no studies in which fasting serum ionic fluoride (SIF) concentrations in a general population were investigated despite the fact that SIF has various activities in humans. METHODS: A total of 332 healthy subjects (167 men and 165 women aged 40 to 69years) were selected from residents of 2 towns
Ionic plasma fluoride concentrations related to some diseases in patients from a fluoridated community
Little data is available concerning the relationship between variations in ionic plasma fluoride (IPF) concentrations and some diseases, and that which exists is inconclusive. The effect of renal insufficiency is known best, but the relationship between IPF levels and some oedematous diseases and diabetes has hardly been studied at all
Diagnosis of fluorosis and recovery through easy to practise interventions.
The objectives of the present study were to highlight (i) how to diagnose fluorosis, due to fluoride ion (F) toxicity, in out-patient departments, by retrieving the history and through tests and (ii) the interventions available for recovery. In patients suspected of fluorosis, the F levels were investigated in samples of
The effect of hemodialysis upon serum levels of fluoride
Serum and dialysate ionic fluoride (F-) were determined in 29 patients under hemodialysis (HD) treatment. Serum creatinine (Cr), blood urea nitrogen (BUN) and phosphorus (P) were also examined before and after HD in 92 patients including the above 29 patients under the same treatment. Results reveal that serum F- levels
Human urinary fluoride excretion as influenced by renal functional impairment
The effects of renal function on human renal fluoride (F-) excretion and serum F- concentrations were studied in subjects with normal renal function, in patients with variable degrees of renal insufficiency and in patients undergoing regular hemodialysis treatment. The mechanisms of human renal F- excretion include glomerular filtration and tubular
