Abstract
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 just south of Lake Van in the eastern part of Turkey were investigated. In the kidney tissues, the MDA levels and SOD activities in the fluorosed sheep showed nonsignificant increases, but the GSH level and GPx activities significantly decreased. In the liver tissues of the fluorosed sheep, a significant increase in the MDA level and GPx activity was observed, but the GSH level showed no change, and the SOD activity exhibited a small decrease. By contrast, in the muscle tissues, the MDA level decreased and the SOD activity increased significantly, whereas the GPx activity increased but not significantly, and the GSH levels decreased. Finally, the serum lipoprotein levels of the fluorosed and nonfluorosed sheep were not significantly different. In conclusion, different degrees in the pro-oxidant/antioxidant status of soft tissues such as kidney, liver, and muscle were affected by F intoxication, but no differences were found in the serum lipoprotein levels.

Effects of melatonin and epiphyseal proteins on fluoride-induced adverse changes in antioxidant status of heart, liver, and kidney of rats
Several experimental and clinical reports indicated the oxidative stress-mediated adverse changes in vital organs of human and animal in fluoride (F) toxicity. Therefore, the present study was undertaken to evaluate the therapeutic effect of buffalo (Bubalus bubalis) epiphyseal (pineal) proteins (BEP) and melatonin (MEL) against F-induced oxidative stress in heart,

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

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

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

Fluoride, Blood Pressure and Hypertension
Individuals with blood pressure readings that exceed 140/90 are considered hypertensive. Hypertension can increase the risk of stroke, heart attack, heart failure, aortic aneurysms, and peripheral arterial disease. An association between increased fluoride in ground water and increased prevalence of hypertension has been observed, especially among adult males (Amini et

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 & Myocardial Damage
Structural damage to the heart resulting from fluoride toxicity has been observed in numerous human and animal studies. The general features of this damage include cloudy swelling, vacuolization or vacuolar degeneration, hemorrhages, interstitial edema, fibrous necrosis, dissolution of nuclei, and thickening of the vessel walls in the heart muscle (Basha

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

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
