Abstract
The effects of prolonged enflurane and halothane administration on urine-concentrating ability were determined in volunteers by examining their responses to vasopressin before anesthesia and on days 1 and 5 after anesthesia. A significant decrease in maximum urinary osmolality of 264 +/- 34 mOsm/kg (26 per cent of the preanesthetic value) was present on day 1 after enflurane anesthesia, whereas subjects anesthetized with halothane had a significant increase in maximum urinary osmolality of 120 +/- 44 mOsm/kg. Serum inorganic fluoride level peaked at 33.6 muM and remained above 20 muM for approximately 18 hours. Thus, the threshold level for inorganic fluoride nephrotoxicity is lower than previously suspected.

Role of Some Natural Antioxidants in the Modulation of Some Proteins Expressions against Sodium Fluoride-Induced Renal Injury.
Background: The aim of the present work is to find the effects of N-acetylcysteine (NAC) and/or thymoquinone (THQ) in the protection against acute renal injury induced by sodium fluoride (NaF). Method: Rats were distributed into five groups: G1 was normal (control), G2 was intoxicated with 10mg/kg NaF i.p., G3 was treated

Pathological changes in the tissues of rats (albino) and monkeys (macaca radiata) in fluorine toxicosis
1. Stomach, duodenum, small intestine, kidney, liver, spleen, skin, heart, aorta, lungs, brain, pancreas, adrenals, thyroid and parathyroid of rats and monkeys suffering from chronic fluorosis have been histologically examined. 2. Fluorine has not been found to have any effect on the heart muscle, aorta, skin and parathyroids, whereas it has

Histological and histochemical appearance of livers and kidneys of rats after long-term treatment with different concentrations of sodium fluoride in drinking water
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

Chronic Kidney Disease in the United States, 2019
With chronic kidney disease (CKD), kidneys become damaged over time or cannot clean the blood as well as healthy kidneys. When the kidneys don’t work well, wastes and extra water build up in the body and may cause other health problems, including heart disease and high blood pressure. However, people

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.

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
