Abstract
Sodium fluoride was administered at 0, 25, 50, 100, and 150 ppm F in drinking water for 4 weeks to Institute of Cancer Research (ICR) derived glomerulonephritis (ICGN) mice. Fluoride was also administered to ICR mice at 0 and 150 ppm. Blood was sampled from the tail artery of each mouse twice a week for the determination of blood urea nitrogen (BUN) and creatinine (CRE). All ICGN mice in the 150 ppm F group and 4 of 9 in the 100 ppm F group died before the end of four weeks, but no ICR control mice died. The mean values of BUN and CRE in the serum of the 150 ppm ICGN mice were significantly higher than those in the ICGN control mice at the end of the exposure period. The mean relative liver weight of the 150 ppm ICGN mice was significantly lower than that of the ICGN control mice. We conclude that F significantly exacerbates renal dysfunction.

Study on changes of clinical indicators and key proteins from fluoride exposure
Few studies have evaluated the biomarker changes of fluoride exposure. In order to explore early and sensitive indicators, animal experiment was designed. Ninety-six healthy SD rats (48 males and 48 females) weighing approximately 60 g were randomly divided into six groups of 16 animals each by gender average. Control animals

Studies on the DNA and RNA contents of heart, liver and kidney of rats with chronic fluorosis
17 rats with chronic fluorosis induced by prolonged drinking of water containing 50 ppm fluorine and 17 rats drinking low-fluorine water served as control were used to study the DNA and RNA contents of heart, liver and kidney. The findings suggest that excessive accumulation of fluorine can suppress the synthesis

Oxidative stress parameters in rats exposed to fluoride and caffeine
In our experiment, the 1-month effects of caffeine (Caff) and fluoride (F) administered separately and together on nitric oxide and total antioxidant status in serum, brain, liver and kidney of rats were investigated. Also, the influence of caffeine on fluoride excretion with urine was studied. Thirty adult male Wistar rats

Effect of fluoride on major organs with the different time of exposure in rats.
BACKGROUND: High fluoride levels in drinking water in relation to the prevalence of chronic kidney disease of unknown etiology (CKDu) in Sri Lanka were investigated using rats as an experimental model. METHOD: The effects of fluoride after oral administration of Sodium fluoride (NaF) at levels of 0, 0.5, 5 and 20 ppm F- were evaluated

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 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

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
