Urinary biomarkers monitoring for experimental fluoride nephrotoxicity

An excess of sodium fluoride (135 mg F/kg body weight) was given in a single oral dose to male Wistar rats. Effects were investigated of fluoride-induced acute kidney intoxication on the time-dependent variations of urine volume. Also, of urinary fluoride ion (F-), alpha-glutathione-S-transferase (alpha-GST), N-acetyl-beta-D-glucosaminidase (NAG), and creatinine (CR) concentrations.

Chronic toxicity of dietary sodium monofluorophosphate in growing rats, with special reference to kidney changes

Changes in fluoride levels in the liver, kidney, and brain and in neurotransmitters of mice after subacute administration of fluoride

The effects of fluoride after subacute oral administration of NaF at levels of 0, 1, 5, 25, and 125 ppm F– were evaluated in adult male BALB/c mice. Fluoride levels in the murine liver, kidney, and cerebrum after one month were determined using a highly sensitive flow-injection apparatus with a

Fluorosis in Aden

The cases to be described here occurred in the Aden Protectorate where for the last 12 years mass screening of the chest to exclude pulmonary tuberculosis has been carried out. The patients had all drunk the brackish water from the wells, and the analysis of the water from a well

Chronic kidney diseases of uncertain etiology (CKDue) in Sri Lanka: geographic distribution and environmental implications

The increase in the number of chronic kidney disease (CKD) patients from the north central region of Sri Lanka has become a environmental health issue of national concern. Unlike in other countries where long-standing diabetes and hypertension are the leading causes of renal diseases, the majority of CKD patients from

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 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

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 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

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
