The fluoride sensitivity of cells released from rat livers and kidneys by collagenase perfusion was investigated by measuring effect on protein synthesis rate in vitro. Both cell types were sensitive to fluoride with clear concentration/effect relationships. Significant difference in sensitivity for fluoride between the cell types was found, with the kidney cells being the most sensitive type.
[Study on the relationship between renal apoptosis and expression of caspase protein in fluoride induced rat].
OBJECTIVE: To study the relationship between death receptor pathway, mitochondrion pathway and fluoride-induced apoptosis of renal cell. METHODS: Male Sprague-Dawley rats were divided randomly into four groups (control, low-fluoride, medium-fluoride,and high-fluoride) and administered 0, 50, 100, and 200 mg/L of sodium fluoride, respectively, via drinking water for 120 days. The incidence
Renal tubular site of action of fluoride in Fischer 344 rats
Methoxyflurane is capable of producing high-output renal failure in some patients and animal models, probably through metabolic liberation of free fluoride. The tubular site of action of fluoride was examined in Fischer 344 rats using clearance techniques. Free water reabsorption (TCH2O) and free water excretion (CH2O) were measured during mannitol
Exposure to excessive fluoride during hemodialysis.
The safety of fluoridated community water supplies for dialysate and long-term intermittent hemodialysis has been questioned since 1965 . The only significant means of clearing fluoride from body fluids are renal excretion and incorporation into bone . When dialysate is prepared with fluoridated water, fluoride ion moves along a concentration
Role of Some Natural Antioxidants in the Modulation of Some Proteins Expressions against Sodium Fluoride-Induced Renal Injury.
Background: The aim of the present work is to find the effects of N-acetylcysteine (NAC) and/or thymoquinone (THQ) in the protection against acute renal injury induced by sodium fluoride (NaF). Method: Rats were distributed into five groups: G1 was normal (control), G2 was intoxicated with 10mg/kg NaF i.p., G3 was treated
Serum fluoride concentrations and exocrine kidney function with sevoflurane and enflurane. An open, randomized, comparative phase III study of patients with healthy kidneys.
Sevoflurane is a "new" volatile inhaled anaesthetic. Owing to its lower blood-gas solubility coefficient, emergence from anaesthesia is faster with sevoflurane than with isoflurane, enflurane, or halothane. Sevoflurane undergoes metabolic biodegradation, releasing inorganic fluoride ions that could produce nephrotoxicity. In this study, we compared serum inorganic fluoride concentrations (IFCs) in
