Abstract
The effects of sodium-fluoride (7681494) on gastric secretion were studied in rats. Male albino-rats were administered 25 milligrams per kilogram sodium-fluoride in their drinking water for 60 days. Selected rats were killed after 7, 15, 30, and 60 days, and stomachs were dissected out, the gastric juice collected, and the volume recorded. After centrifugation to remove suspended food particles, the gastric juice was analyzed for free and total acidity. Peptic activity was determined. Gastric volume was significantly increased after 30 and 69 days of sodium-fluoride treatment. Total acidity increased progressively with duration of treatment. Free acidity was significantly increased after 30 and 60 days. The increase in total acidity at 30 and 60 days was mainly due to the increase in free acidity. Peptic acidity was increased at all time points in treated animals, with the greatest increases occurring after 30 and 60 days. The authors suggest that elevation of cyclic-adenosine-monophosphate concentrations in the stomach by sodium-fluoride can stimulate hydrogen ion output. This could explain the gastric symptoms of individuals in endemic fluorosis areas and workers exposed to air contaminants containing fluoride.

The effect of fluorine exposure on morphological indicators and intestinal microbial community in Bufo gargarizans tadpoles.
Highlights Fluoride declined total body length and body weight of tadpoles. Fluoride resulted in alteration of intestinal microbial community. Fluoride triggered histological changes in the gut. Fluoride induced metabolic disorder in tadpoles. In this study, Bufo gargarizans (B. gargarizans) tadpoles were exposed to different fluorine concentrations (0, 0.5, 5 and 50?mg/L

Skeletal fluorosis mimicking seronegative arthritis
Fluorosis is endemic in certain parts of the world, especially the Asian subcontinent (1). We report an unusual presentation of fluorosis mimicking seronegative spondyloarthritis. Although fluorosis is known to cause irritable bowel syndrome-like disorder and joint pain, this could be wrongly diagnosed as a case of seronegative arthritis. Case report A 35-year-old

Treatment of primary osteoporosis with fluoride and calcium: clinical tolerance and fracture occurrence
Thirty-six patients with primary osteoporosis were treated for up to six years with sodium fluoride, calcium supplements, and, in 24 patients, vitamin D. Major adverse reactions (synovitis, painful plantar fascial syndrome, recurrent vomiting, or anemia) occurred in 15 patients (42%). New vertebral fractures occurred at a rate of 329 fractures

Fluoride as a possible aetiological factor in non-ulcer dyspepsia
A prospective case controlled study was conducted to evaluate the role of fluoride as a possible aetiological factor for non-ulcer dyspepsia (NUD). Twenty patients with NUD and 10 age and sex matched healthy controls were subjected to clinical evaluation, upper gastrointestinal endoscopy and biopsies from the gastric antrum and duodenum.

Massive fluorosis of bones and ligaments
Summary The authors record the results of their clinical examination of 78 workers engaged in the crushing and refining of cryolite. Beside silicosis -- to as much as the second degree -- which was present in 39, the following three diseases were found to be common in these workers: 1) a curious

Gastrointestinal Problems Among Individuals with Skeletal Fluorosis
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

Fluoride & Gastrointestinal System: The Importance of Fluoride Concentration in Stomach
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. The

Fluoride-Induced Gastric Symptoms in Human Clinical Trials
In studies where fluoride has been used (at doses of 18-34 mg/day) as an experimental drug for the treatment of osteoporosis, gastrointestinal disturbances are one of the two main side effects consistently encountered. The following are some of the accounts from the published literature: "The use of fluoride in the prophylaxis or

Fluoride-Induced Damage to Gastric Mucosa in Human Clinical Trials
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

Side Effects from Fluoride Gels: Gastric Distress
Gastric distress -- including nausea, pain, and vomiting -- is one the most common side effects from professional application of "fluoride gels" at the dentist. Patients receiving fluoride gels can swallow more than 20 mg of fluoride from a single treatment -- doses that far exceed the doses that can
