HF exposure might produce adverse effects in industrial workers. A 3 mo. exposure of rats to HF at 10 mg/m3 8 h/day 5 days/wk resulted in increased blood serum concentrations of hydroxyproline and hydroxylysine and in enhanced urinary excretion of these amino acids and in changes of collagen fractions in the liver, lungs and skin. In all tissues studied (especially liver), soluble and insoluble collagen decreased. HF affected biosynthesis and maturation of collagen fibers.
Investigations of soft tissue functions in fluorotic individuals of North Gujurat
The present study was undertaken to investigate the various health problems caused by water-borne fluoride in endemic villages of Mehsana and Banaskantha districts of Gujarat. The study revealed high levels of fluoride in serum samples of the villagers. Mottling of teeth and skeletal complications were common. Intake of fluoride caused
Influence of methionine upon the concentration of malondialdehyde in the tissues and blood of rats exposed to sodium fluoride
The aim of the study has been to determine the influence upon the kidney, liver, and the blood prooxidative system, exercised by administration of methionine (Met), under conditions of oxidative stress induced by sodium fluoride (NaF).The experiment was carried out on Wistar FL rats (adult females) that, for 35 days,
Influence of sodium fluoride and caffeine on the concentration of fluoride ions, glucose, and urea in blood serum and activity of protein metabolism enzymes in rat liver.
The aim of the study was examining the effect of fluoride ions and caffeine administration on glucose and urea concentration in blood serum and the activity of protein metabolism enzymes and selected enzymes of the urea cycle in rat liver. The study was carried out using 18 male Sprague-Daowley rats
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
Lipid peroxidation in fluorosis and the protective role of dietary factors
The influence of chronic Fl intoxication on lipid peroxidation and the state of the antioxidant system was studied in rats on different diets. Chronic Fl intoxication inhibited antioxidant activity and caused an increase in the rate of peroxidation and the level of lipoperoxides in liver, brain and serum. Diets with
