Abstract
Evidence suggests that certain tissues of the body are affected by inorganic fluoride in the diet. Groups of CSE female mice received different concentrations of fluoride in their drinking water for approximately 26 weeks. Slight variation in water and food intake was observed among the groups. Histological observation revealed pathological changes in thyroid, kidney, liver and spleen in mice receiving as little as 1 ppm fluoride.

Changes in the metabolism of glucose and calcium following a single large dose of fluoride to rats
Serum glucose level was elevated immediately after ip administration of a single large dose of fluoride (NaF 35 mg/kg) to rats. The elevation of serum glucose was markedly suppressed by adrenalectomy, dibenamine or propranolol, but not by thyroid-parathyroidectomy. Elevation of serum glucose was found to be associated with enhancement of

Experimental rat model for acute tubular injury induced by high water hardness and high water fluoride: efficacy of primary preventive intervention by distilled water administration.
BACKGROUND High water hardness associated with high water fluoride and the geographical distribution of Chronic Kidney Disease of unknown etiology (CKDu) in Sri Lanka are well correlated. We undertook this study to observe the effects of high water hardness with high fluoride on kidney and liver in rats and efficacy of

Subchronic neurotoxicity in rats of the structural fumigant, sulfuryl fluoride
Inhalation exposure of male and female Fischer 344 rats to sulfuryl fluoride [Vikane (Dow Chemical Company) gas fumigant] at 300 ppm for 6 hr/day, 5 days week, for 13 weeks caused diminished weight gain, dental fluorosis, a slight decrease in grooming, decreased flicker fusion threshold, slowing of flash, auditory and

Studies on effects of fluoride in 36 villages of Mehsana District, North Gujurat"
A survey was carried out in 36 fluoride endemic villages of Mehsana District of North Gujarat. Urine and blood samples of fluoride-afflicted human population and their drinking water were analysed for fluoride content and compared with samples from different parts of Ahmedabad city (control). The fluoride content in water samples

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

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

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

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

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
