Abstract

The hyperglycemia which accompanies acute fluoride toxicity in the rat is mediated by epinephrine released from the adrenal medulla. Bilateral splanchnicotomy prevented this response to fluoride. Ganglionic blockade diminished the hyperglycemic response in unanesthetized animals but not in pentobarbital-anesthetized animals. Microinjections of fluoride into the lateral ventricle elicited a rapid hyperglycemia in unanesthetized animals which again was blocked partially by ganglionic blockade. The response to fluoride appears to be mediated primarily by splanchnic impulses arising in the central nervous system.

    Excerpts: Summary Under the Safe Drinking Water Act, the U.S. Environmental Protection Agency (EPA) is required to establish exposure standards for contaminants in public drinking-water systems that might cause any adverse effects on human health. These standards include the maximum contaminant level goal (MCLG), the maximum contaminant level (MCL), and the secondary

  • 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

  • Fluoride exposure impairs glucose tolerance via decreased insulin expression and oxidative stress.

    Chronic exposure to high fluoride (F(-)) may lead to local tissue disturbances, known as fluorosis. F(-) is an oxidising agent and a well-known reversible enzymatic inhibitor that interferes with the enzyme activity of at least 80 proteins. The goals of the current study were to evaluate whether F(-) exposure affected

    The authors' research focuses on polyuria, natriuresis, glucosuria, glycemia, and renal calcification in occupational lead poisoning and endemic fluorosis. Changes in electrolyte mobilization and in glucose metabolism and transport following the administration of lead compounds or fluoride were examined to elucidate these mechanisms. The results suggest fundamental approaches to the

    The aim of this work was to examine the effect of fluoride ions on antioxidative enzyme activity in the pancreas of rats exposed during 4 months to NaF in drinking water. The study was carried out in 30 four-week-old male Wistar FL rats, that were randomly assigned to three equal

  • Fluoride & Impaired Glucose Tolerance

    The proper regulation of blood glucose levels is essential to good health. When the body's ability to regulate blood glucose levels falters, as occurs in diabetes mellitus, chronic elevated glucose levels (hyperglycemia) can lead to serious complications. These consequences include damage to the kidneys, nervous system, cardiovascular system, retina, legs
