Abstract
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 revealed, in 45 per cent of the treated animals, some alterations at the expense of the tubular epithelium whose cells showed signs of having been affected by the salt-fluor to the point of necrosis, with occlusion in some cases of tubular lumen.
As regards the liver, the authors observed in 35 per cent of the rats submitted to treatment, slight cellular alterations, whereas the shape of the liver appeared generally well preserved.
On the whole the renal alterations were not important; nevertheless, though admitting the not perfect correspondence of what is to be seen in experimental animals with what presumably happens in man, the authors think that the experimental control of a drug like fluor, supplied to a whole population through the fluoration of drinking waters, must furnish unmistakable data in so far as no difference has been noticed between the control and experimental groups. The authors, therefore, conclude by stating the need of further biological controls demonstrating also the actual harmlessness of fluor in prophylactic doses for decayed teeth.

Fluoride-induced histopathology and synthesis of stress protein in liver and kidney of mice
Selective low (15 mg sodium fluoride (NaF)/L) and relatively high (150 mg NaF/L) doses of in vivo fluoride (F) treatment to Swiss albino mice through drinking water elicited organ-specific toxicological response. All the F-exposed groups showed severe alterations in both liver and kidney architectures, but there was no significant change

Protective effects of blackberry and quercetin on sodium fluoride-induced oxidative stress and histological changes in the hepatic, renal, testis and brain tissue of male rat
BACKGROUND: Sodium fluoride (NaF) intoxication is associated with oxidative stress and altered antioxidant defense mechanism. The present study was carried out to evaluate the potential protective role of blackberry and quercetin (Q) against NaF-induced oxidative stress and histological changes in liver, kidney, testis and brain tissues of rats. METHODS: The rats

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,

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

Cyperus esculentus suppresses hepato-renal oxidative stress, inflammation, and caspase-3 activation following chronic exposure to sodium fluoride in rats’ model.
Background Death arising from hepato-renal related diseases is on the increase. Cyperus esculentus (CE) possesses antioxidants potentials. This study aim at investigating the effect of Cyperus esculentus on sodium fluoride (NaF)-induced hepato-renal toxicity in rats. Methods Twenty-four male rats weighting (10–12 weeks old, 200± 20 g) randomized into group A (control) received 1 ml normal

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
