Abstract
An experiment was carried out on Sprague-Dawley rats (adult males) that for 50 days were administered, in the drinking water, NaF and NaF with caffeine (doses, respectively: 4.9 mg of NaF/kg body mass/24 h and 3 mg of caffeine/kg body mass/24 h). Disturbances were noted in the functioning of kidneys, which were particularly noticeable after the administration of NaF with caffeine. Changes in the functioning of kidneys were also confirmed by such parameters as the level of creatinine, urea, protein, and calcium. Modifications of the enzymatic antioxidative system (superoxide dismutase, catalase, and glutathione peroxidase) and lipid peroxidation (malondialdehyde) were also observed. Changes in the contents of the above parameters as well as pathomorphological examinations suggest increased diuresis, resulting in dehydration of the rats examined.

Ameliorative effect of tamarind leaf on fluoride-induced metabolic alterations
OBJECTIVES: Fluoride is a serious health hazard across several nations, and chronic intake of fluoride deranges the carbohydrate, lipid and antioxidant metabolism in general. As there are limited remedial measures to prevent fluorosis, we investigated the role of tamarind leaf as a food supplement in restoration of carbohydrate, lipid and

Conceivable amelioration of NaF-induced toxicity in liver, kidney and brain of chicken by black tea extract: an in vitro study.
Sodium fluoride (NaF) toxicity on enzymatic and non-enzymatic oxidative stress markers of chicken liver, kidney and brain homogenate in in vitro condition where studied in present investigation. We studied alteration in the activity of superoxide dismutase (SOD), catalase (CAT), lipid peroxidation (LPO) and glutathione (GSH) content to study oxidative stress.

Ameliorative effects of quercetin on sodium fluoride-induced oxidative stress in rat's kidney
OBJECTIVE: The in vivo nephroprotective effect of quercetin against sodium fluoride (NaF)-induced damage was studied. METHODS: Renal injury was induced by daily administration of NaF (600 ppm) through drinking water for 1 week. The levels of reduced glutathione (GSH), lipid peroxidation as well as superoxide dismutase and catalase activity of

Induction of oxidative stress on reproductive and metabolic organs in sodium fluoride-treated male albino rats: protective effect of testosterone and vitamin E coadministration
The present study was undertaken to search out the effect of sodium fluoride, a water pollutant noted throughout the world, including India, on oxidative stress induction in reproductive tissues, sperm pellet, and metabolic tissues like the liver and kidney. The protective effects of testosterone or vitamin-E coadministration were also observed

Evaluation of free radical-scavenging and anti-oxidant properties of black berry against fluoride toxicity in rats
Oxidative damage to cellular components such as lipids and cell membranes by free radicals and other reactive oxygen species is believed to be associated with the development of degenerative diseases. Fluoride intoxication is associated with oxidative stress and altered anti-oxidant defense mechanism. So the present study was extended to investigate

Fluoride & Oxidative Stress
A vast body of research demonstrates that fluoride exposure increases oxidative stress. Based on this research, it is believed that fluoride-induced oxidative stress is a key mechanism underlying the various toxic effects associated with fluoride exposure. It is also well established that fluoride's toxic effects can be ameliorated by exposure

Nutrient Deficiencies Enhance Fluoride Toxicity
It has been known since the 1930s that poor nutrition enhances the toxicity of fluoride. As discussed below, nutrient deficiencies have been specifically linked to increased susceptibility to fluoride-induced tooth damage (dental fluorosis), bone damage (osteomalacia), neurotoxicity (reduced intelligence), and mutagenicity. The nutrients of primary importance appear to be calcium,

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

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.

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
