Effect of sodium fluoride on concentrating and diluting ability in the rat

Mechanisms for the concentrating defect produced by fluoride were examined in the rat. Free-water clearance at all levels of delivery was normal after 5 days of chronic fluoride administration in the hereditary hypothalamic diabetes insipidus rat. In the Sprague-Dawley rats, during moderate fluoride administration (120 micronmol/kg per day), urine osmolality

Investigation on the effect of Hibiscus Sabdariffa calyxethanolic extract on sodium fluoride induced fluorosis in rats

Flu o rosis was induced by the oral administration of Sodium Fluoride (10mg/kg) for 30 days. On 30th day the Flurosis was confirmed by studying the level of fluorine in serum and urine. Treatment was started from 30th day to 60th day by ingesting Hibiscus Sabdariffa calyxethanolic extract 200 mg/kg and

Protective effect of royal jelly on fluoride-induced nephrotoxicity in rats via the some protein biomarkers signalling pathways: a new approach for kidney damage.

Introduction Protective effect of royal jelly (RJ) on fluoride-induced nephrotoxicity was investigated in this study. Methods 42 healthy male Wistar rats (n = 42, 8 weeks of age) were divided equally into 6 groups with 7 rats in each; (1) Group-1: Controls fed with standard diet; (2) Group-2: RJ [100 mg/kg] bw (body

Fluorosis caused cellular apoptosis and oxidative stress of rat kidneys

As the strongest electronegative element, fluorine can stimulate the production of superoxide radicals in cells. In view of the important roles of kidneys in bone metabolism, the authors analyzed the quantitative pathomorphological characteristics of renal damage and the potential cellular apoptosis and oxidative stress mechanisms in rats treated with excessive

The in vitro and in vivo effects of fluoride on succinic dehydrogenase activity

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 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 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 & 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

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.
