Abstract

Sodium fluoride (NaF) toxicity on enzymatic and non-enzymatic oxidative stress markers of chicken liver, kidney and brain homogenate in in vitro condition where studied in present investigation. We studied alteration in the activity of superoxide dismutase (SOD), catalase (CAT), lipid peroxidation (LPO) and glutathione (GSH) content to study oxidative stress. Ameliorative effect of aqueous extract of black tea (AQBT) on NaF induced alteration was also studied. Six different dosages i.e. from 200 to 700 ?g/ml of NaF were selected by pilot experiments and used for present study. Each dose incubated in triplicate with homogenate of liver, kidney and brain of chicken at 37?C for four hours. After incubation, content of the tube was used for the analysis of oxidative stress parameters. Results revealed statistically significant alterations in these enzymatic and non-enzymatic parameters at all dosage. AQBT at different dosage viz., 200 to 500 ?g/ml shows statistically significant alleviation when incubate along with NaF (700 ?g/ml) for four hours. AQBT at 100 ?g/ml was also shown certain amelioration but it was not statistically significant. Therefore, it could be concluded that NaF can significantly produce oxidative stress in liver, kidney and brain of chicken in in vitro condition which can successfully alleviatedby AQBT.

    BACKGROUND: Sodium fluoride (NaF) intoxication is associated with oxidative stress and altered antioxidant defense mechanism. The present study was carried out to evaluate the potential protective role of blackberry and quercetin (Q) against NaF-induced oxidative stress and histological changes in liver, kidney, testis and brain tissues of rats. METHODS: The rats

    In our experiment, the 1-month effects of caffeine (Caff) and fluoride (F) administered separately and together on nitric oxide and total antioxidant status in serum, brain, liver and kidney of rats were investigated. Also, the influence of caffeine on fluoride excretion with urine was studied. Thirty adult male Wistar rats

    Flavonoids have been extensively studied and reported to possess widespread biological activities, including antioxidant and chelating properties. They have been proposed to exert beneficial effects in a multitude of diseased states generated due to oxidative stress. Therapeutic efficacy of oral administration of Silymarin and Quercetin after fluoride exposure (50 ppm

  • Systematic impacts of fluoride exposure on the metabolomics of rats.

    Highlights The risk of chronic endemic fluorosis exists in many countries and regions. Comprehensive metabolomic analysis was used to study the effects of fluoride. Multivariate statistics were used to detect metabolite profile changes. Fluoride exposure caused amino acid, fatty acid, and energy metabolism disorders. Fluoride exposure caused oxidative stress,

    17 rats with chronic fluorosis induced by prolonged drinking of water containing 50 ppm fluorine and 17 rats drinking low-fluorine water served as control were used to study the DNA and RNA contents of heart, liver and kidney. The findings suggest that excessive accumulation of fluorine can suppress the synthesis

  • Nutrient Deficiencies Enhance Fluoride Toxicity

    It has been known since the 1930s that poor nutrition enhances the toxicity of fluoride. As discussed below, nutrient deficiencies have been specifically linked to increased susceptibility to fluoride-induced tooth damage (dental fluorosis), bone damage (osteomalacia), neurotoxicity (reduced intelligence), and mutagenicity. The nutrients of primary importance appear to be calcium,

    An association between elevated fluoride exposure and reduced intelligence has now been observed in 65 IQ studies.

This animal research includes the following 45 studies (out

    The human placenta does not prevent the passage of fluoride from a pregnant mother's bloodstream to the fetus. As a result, a fetus can be harmed by fluoride ingested pregnancy. Based on research from China, the fetal brain is one of the organs susceptible to fluoride poisoning. As highlighted by the excerpts

    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

    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.
