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

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

Influence of increasing fluoride dose rates on selected liver and kidney enzymes profile in domestic chicken (Gallus domesticus)
Fluoride has been considered to cause hepatic and renal tissue damages in animals and humans. The present study investigated the effect of varying concentrations of fluoride on hepatic and renal enzyme profile in domestic chicken (n= 80). Chickens were distributed into 4 groups. Group A was kept unexposed while group

[Renal and hepatic changes in albino rats treated with NaF microdose]
The authors, in order to study histologically the effect on the liver and kidneys of salt-fluor, have administred NaF orally to eighty rats, at the dosage of 0.02 mg % per kg of weight. The animals were decapitated on the 180th day of the experiment. The histological test of the kidneys

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

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 & 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
