Abstract

Gastroscopy to 35 patients with fluorosis, 32 with arsenic-fluorosis, and 25 control had been performed to study the influence of fluorosis on arsenic-fluorosis on the gastric mucosa. There was significant difference on gradient and activity of chronic gastritis among the three groups, but there was no significant difference in the fluorosis and arsenic-fluorosis [groups]. It appears that pathological changes of gastric mucosa of fluorosis and arsenic-fluorosis may be caused only by fluorosis.

  • Gut microbiota perturbations and neurodevelopmental impacts in offspring rats concurrently exposure to inorganic arsenic and fluoride.

    Many “hot spot” geographic areas across the world with drinking water co-contaminated with inorganic arsenic (iAs) and fluoride (F-), two of the most common natural contaminants in drinking water. Both iAs and F- are known neurotoxins and affect neurodevelopment of children. However, very few studies have investigated the neurodevelopmental effects

  • Co-exposure to inorganic arsenic and fluoride prominently disrupts gut microbiota equilibrium and induces adverse cardiovascular effects in offspring rats.

    Highlights Co-exposure to arsenic and fluoride leads to adverse cardiovascular effects. Co-exposure to arsenic and fluoride results in gut microbiota perturbations. Co-exposure causes more prominent effects than arsenic or fluoride alone. Strong correlations are identified between cardiovascular effects and significantly altered genera. Co-exposure to inorganic arsenic (iAs) and fluoride (F-)

  • Effects of high fluoride and arsenic on brain biochemical indexes and learning-memory in rats

    Nine-six Wistar rats were randomly divided into four groups of 24 rats in each group (female:male = 1:1). Over a period up to 90 days, with one untreated group as controls, the other three groups were administered, respectively, high fluoride (100 mg NaF/L), high arsenic (50 mg As2O3/L), or both

  • Behavioral and general effects of subacute oral arsenic exposure in rats with and without fluoride

    Consequences of oral arsenic and fluoride exposure on motor behavior and general toxicity were modeled in young adult male rats which received sodium (meta)arsenite (10 mg/kg-b.w.), sodium fluoride (5 mg/kg-b.w.), and their combination by gavage, once daily, 5 days a week for 6 weeks. After 6 weeks, 6 animals per group were dissected, while the

  • Effect of arsenic and/or fluoride gestational exposure on renal autophagy in offspring mice.

    Highlights The exposure of fluoride and arsenic in the mother rats induced the autophagy in the kidney of the offspring mice. Under the experimental conditions, the combination of As and F showed certain antagonistic effects. The expression of autophagy negative regulator p62 is increased, which may be due to autophagic

    The following is an excerpt from the National Research Council's (2006) review of fluoride toxicity: "It is important to realize that GI effects depend more on the net concentration of the aqueous solution of fluoride in the stomach than on the total fluoride dose in the fluid or solid ingested.

    Humans suffering from skeletal fluorosis are known to suffer from an increased occurrence of gastrointestinal disorders. When fluoride intake is reduced, these gastrointestinal problems are among the first symptoms to disappear. The following are some of the studies that have examined this issue: "It is clear from the observations presented in this article

    When fluoride has been used (at doses of 18-34 mg/day) as an experimental treatment for osteoporosis, gastric pain is one of the two main side effects consistently encountered. To better understand how fluoride causes this effect, researchers have sought to determine how fluoride affects the tissue that lines the gastrointestinal tract. In a
