Effect of sodium fluoride on the expression of Bcl-2 family and osteopontin in rat renal tubular cells
Our earlier studies showed that the apoptosis of renal tubules can be induced by sodium fluoride (NaF). The present study was designed to estimated the effects of B-cell lymphoma/leukemia 2 (Bcl-2), Bcl-2-associated protein X (Bax), and osteopontin (OPN) on the apoptosis of renal tubular cells induced by NaF at different

Effect of high fluorine (F) intake on tissue lead (Pb) concentrations
Four groups of 10 male, albino Sprague Dawley rats receiving either deionized water or deionized water containing 300 parts per million (ppm) F as NaF, 200 Pb as Pb acetate or F+Pb at 300 and 200 ppm, respectively, as drinking water for 10 weeks were fed a casein-based purified diet.

Prevention of brick tea fluorosis in rats with low-fluoride brick tea on laboratory observation
To test whether low-fluoride brick tea can prevent the occurrence of fluorosis, rats had access only to a specially prepared low-fluoride brick tea for 1 year. The daily fluoride intake, fluoride metabolism, tissue distribution and development of tooth fluorosis were observed at 4-monthly intervals, at the end of months 4,

Protective effect of Tamarindus indica fruit pulp extract on collagen content and oxidative stress induced by sodium fluoride in the liver and kidney of rats
Fluorosis is a serious public health problem in many parts of the world. The generation of reactive oxygen species and lipid peroxidation has been considered to play an important role in the pathogenesis of chronic fluoride toxicity. The present study was undertaken to evaluate the protective effect of Tamarindus indicafruit pulp extract

The effect of 0.05 percent dietary sodium fluoride on the rat kidney
Two hundred and twenty-six white rats were given a diet containing 0.05 per cent sodium fluoride (226 ppm) for periods ranging from 3 to 56 days. It was established that changes in the kidneys occurred regularly after 21-28 days on the diet. The kidney changes consisted primarily in dilatation of the

Fluoride & Kidney Stones
It has long been suspected that fluoride may contribute to the formation of kidney stones. This suspicion has recently gained support from a study of an American man with skeletal fluorosis. According to the authors: "A new, important, medical problem (that seemed temporally related to cessation of fluoride exposure and subsequent negative calcium

Fluoride as a Cause of Kidney Disease in Humans
Because the kidney is exposed to higher concentrations of fluoride than all other soft tissues (with the exception of the pineal gland), there is concern that excess fluoride exposure may contribute to kidney disease - thus initiating a "vicious cycle" where the damaged kidneys increase the accumulation of fluoride, causing

Fluoridation of drinking water and chronic kidney disease: Absence of evidence is not evidence of absence
A fairly substantial body of research indicates that patients with chronic renal insufficiency are at an increased risk of chronic fluoride toxicity. Patients with reduced glomerular filtration rates have a decreased ability to excrete fluoride in the urine. These patients may develop skeletal fluorosis even at 1 ppm fluoride in the drinking water.

Kidney: A potential target for fluoride toxicity
The kidneys are the organ responsible for clearing fluoride from the body. In the process of doing so, the kidneys are exposed to concentrations of fluoride that exceed, by a factor of 50, the concentration of fluoride in human blood. As such, the kidney have long been considered a potential
