Abstract
Kidney damage in distal and proximal tubular function and in glomerular filtration occurred in 40-60 yr olds residing in El Qued an endemic fluorosis area in southern Algeria compared to normals from Algiers. Functional renal disturbances were proportional to the degree of fluoride (F-) accumulation which increased in relation to the level of F- in drinking water, the F- level in nails and the radiological grade of fluorosis.

Changes of acute harmful effects and fluoride kinetics after single intravenous injection of sub-toxic hydrofluoric acid in rats-Renal dysfunction, abnormal serum electrolytes, metabolic acidosis and fluoride kinetics.
Hydrofluoric acid (HFA) is used widely in many industrial processes. There have been many reports on the acute lethal effects of HFA in relation to occupational accidents. This study was designed to investigate the time-dependent harmful effects after exposure of sub-toxic doses. The serum fluoride ion (F) kinetics is also

Subacute fluorosis
A young woman presented with a novel multisystem disease: painful periostitis, osteosclerosis, hypertension, and renal dysfunction. The similarity of some of this clinical picture to fluoride intoxication led to the discovery of massively elevated fluoride levels in serum, urine, and bone. Although initially an enigma, the source of fluoride was

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

Vitamin D deficiency, rickets, and fluorosis in India
Data on the vitamin D status of the populations in a tropical country like India have seldom been documented. Vitamin D deficiency is presumed to be rare. Population studied by the author and others in the country has proved otherwise. Studies were carried out to document the dietary habits, serum

Topical fluorides: effects on physiologic and biochemical processes
The ingestion of fluoride from dentifrices or mouthrinses can contribute substantially to the total daily intake of the ion, even in communities that provide optimally fluoridated drinking water. It is concluded that the frequent and unsupervised use of these products by children six years of age or younger, especially those living in

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 Gels & Kidney Function
Scientists have found that the application of "Fluoride Gels" at the dental office causes very high spikes in the blood fluoride level. The high spikes in blood fluoride levels are a result of three factors: the high concentration of fluoride in the gel (= 12.3 mg of fluoride in each

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

Fluoride as a Cause of Kidney Disease in Animals
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 in
