Abstract
The fluoride sensitivity of cells released from rat livers and kidneys by collagenase perfusion was investigated by measuring effect on protein synthesis rate in vitro. Both cell types were sensitive to fluoride with clear concentration/effect relationships. Significant difference in sensitivity for fluoride between the cell types was found, with the kidney cells being the most sensitive type.

Effects of dialysate calcium and fluoride on bone disease during regular hemodialysis
A previous study indicated that, in patients maintained by hemodialysis, clinically and roentgenographically apparent bone disease appeared almost exclusively when the dialystate calcium concentration was less than 5.7 mg per 100 ml. In the present study, bone biopsy specimens from the iliac crest were studied at the beginning and end

Fluoride metabolism in patients with chronic renal failure
Studies of fluoride metabolism were carried out in patients with chronic renal failure by determining fluoride balances for several weeks. The fluoride intake was due to the analyzed fluoride content of the diet and of the drinking water. The effect of aluminum hydroxide on fluoride metabolism was investigated because this

Serum fluoride concentrations in renal insufficiency
In an area with non-fluoridated water (F content, 0.061 ppm), serum fluoride concentrations as measured with an ion specific electrode were as follows: controls (N = 13), 0.0127 ppm + 0.0057 (mean + SD); renal insufficiency (N = 10), 0.0452 ppm + 0.0151; chronic hemodialysis (N = 11), 0.0424 +

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

Effects of selenium and zinc on renal oxidative stress and apoptosis induced by fluoride in rats.
OBJECTIVE: To study the effects of selenium and zinc on oxidative stress, apoptosis, and cell cycle changes in rat renal cells induced by fluoride. METHODS: Wistar rats were given distilled water containing sodium fluoride (50 mg/L NaF) and were gavaged with different doses of selenium-zinc preparation for six months. Four groups
