Abstract

Serum glucose level was elevated immediately after ip administration of a single large dose of fluoride (NaF 35 mg/kg) to rats. The elevation of serum glucose was markedly suppressed by adrenalectomy, dibenamine or propranolol, but not by thyroid-parathyroidectomy. Elevation of serum glucose was found to be associated with enhancement of glucose-6-phosphatase activities in the liver and kidney of fluoride-treated rats. On the other hand, renal calcium was elevated gradually as compared to the augment of serum glucose and cyclic AMP following the fluoride administration. The elevation of renal calcium was markedly suppressed by thryroid-parathyroidectomy.

  • Topical fluorides: effects on physiologic and biochemical processes

    The ingestion of fluoride from dentifrices or mouthrinses can contribute substantially to the total daily intake of the ion, even in communities that provide optimally fluoridated drinking water. It is concluded that the frequent and unsupervised use of these products by children six years of age or younger, especially those living in

  • Ameliorative effect of tamarind leaf on fluoride-induced metabolic alterations

    OBJECTIVES:  Fluoride is a serious health hazard across several nations, and chronic intake of fluoride deranges the carbohydrate, lipid and antioxidant metabolism in general. As there are limited remedial measures to prevent fluorosis, we investigated the role of tamarind leaf as a food supplement in restoration of carbohydrate, lipid and

  • The effects of fluoridated water on rat urine and tissue cAMP levels

    Male Wistar rats were fed a fluoride deficient diet (less than 0.5 parts/10(6) F), and either distilled water or fluoridated water (1.0 parts/10(6)). By week 3, the control group had urinary excretions of 106 +/- 5 nmol cAMP/day (mean +/- SEM) whereas the experimental group excreted 129 +/- 6 nmol

  • Toxic effects of fluoride on kidney function and histological structure in young pigs

    The effects of chronic fluoride exposure on kidney integrity and histological structure, along with effects on associated enzymes and metabolite changes, were investigated in young pigs. Twenty-four crossbred barrows (Duroc×Landrace×Yorkshire) about 50 days old were randomly divided into three groups of eight pigs each. Groups I, II, and III received

  • Protective effects of blackberry and quercetin on sodium fluoride-induced oxidative stress and histological changes in the hepatic, renal, testis and brain tissue of male rat

    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

    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.

    The kidneys are the organ responsible for clearing fluoride from the body. In the process of doing so, the kidneys are exposed to concentrations of fluoride that exceed, by a factor of 50, the concentration of fluoride in human blood. As such, the kidney have long been considered a potential
