Abstract
After a review of the controversies in the literature, a histologic and histochemical study of the livers and kidneys of 48 albino rats was performed. The animals were placed on a diet containing 1 ppm NaF in demineralized drinking water, or 1, 10 or 100 ppm NaF in tap water during 90 or 180 days. The rats treated with fluoride did not present any abnormalities with respect to weight gain, morphology, behavior, and macroscopic appearance of the livers and kidneys compared to the control animals. Microscopic examination failed to reveal any morphologic alterations in either the cells or the mitochondria of the livers and kidneys. Histochemically, the polysaccharides, the protein reactive groups and the acid and alkaline phosphatases also failed to present any visible alterations. With respect to the lipids, the kidneys and livers of the rats treated for 90 days did not show any fat deposition, whereas those treated for 180 days showed zones of deposition of lipids in the livers and kidneys with different frequencies when compared with the control animals. The association between lipid infiltration and the presence of fluoride in the drinking water, however, was statistically significant only in the livers, hence, the hypothesis that fluorinated water accelerated this process in the treated animals cannot be excluded.

Gaseous Anesthetics.
Introduction The history of anesthesia is a relatively recent one; if one begins with the analgesia dentist, Horace Wells, who discovered the used nitrous oxide during a dental extraction in the early 1800s. The first public showing of anesthesia occurred in October 1846, when ether was used to prevent pain during surgery

Fluoride exposure and kidney and liver function among adolescents in the United States: NHANES, 2013–2016.
Highlights Plasma fluoride concentrations are associated with kidney and liver parameters among United States (U.S.) adolescents Higher water fluoride concentrations are associated with lower blood urea nitrogen among U.S. adolescents Fluoride exposure may contribute to complex changes in kidney and liver related parameters among U.S. adolescents Altered kidney and/or liver

Fluoride in drinking water exacerbates glomerulonephritis and induces liver damage in ICR-derived glomerulonephritis mice
To evaluate the effects of fluoride on the kidney and the liver of ICR-derived glomerulonephritis (ICGN) mice by using laboratory tests and pathological examinations, fluoride was administered to the ICGN mice at 0, 25, 50, 100, and 150 ppm in drinking water for 4 weeks and to the ICR mice,

Evaluation of serum lipoprotein and tissue antioxidant levels in sheep with fluorosis
The aim of this study was to evaluate serum lipoprotein and tissue antioxidant levels of sheep with and without fluorosis living in a volcanic area of Turkey. Fifteen Akkaraman sheep with fluorosis in the A?ri region north of Lake Van and 10 Akkaraman sheep without fluorosis in the Van region

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

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

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 & 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
