Abstract
Inhibition on uptake of D-glucose by isolated intestinal epithelial cells (IIEC) was observed when the fluoride concentration ranged between 0.25 and 5 mM. Active transport was almost completely inhibited at 5 mM. When CaCl2 was added to fluoride, the inhibitory effect on glucose uptake was abolished. Preincubation of IIEC with different concentrations of fluoride (2.5-5.0 mM) for different intervals of time (2-20 min) at different pH levels (6.2-7.8) and temperatures (0-37 degrees C) revealed that the conditions which led to higher uptake of fluoride by IIEC produced maximum inhibition. The degree of inhibition was not appreciably altered by a change in glucose concentrations. A concentration-dependent effect of fluoride on lactic acid and carbon dioxide production by IIEC was also observed.

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

Health problems in fluoride endemic areas of Gaya District
Fluoride (F) was estimated in the groundwater of six blocks (Bodh Gaya, Manpur, Wazirganj, Belaganj, Amas, and Bankebazar) of Gaya District, Bihar, for different physio-chemical properties e.g. pH, total dissolved solids(TDS), conductivity, turbidity, total hardness (TH), calcium, magnesium, iron and fluoride. Morever 93 blood samples from different age groups including

Toxicology and Carcinogenesis Studies of Sodium Fluoride in F344/N Rats and B6C3F1 Mice (Drinking Water Studies)
CASRN: 7681-49-4 Chemical Formula: NaF Molecular Weight: 41.99 Report Date: December 1990 Sodium fluoride is a white, crystalline, water-soluble powder used in municipal water fluoridation systems, in various dental products, and in a variety of industrial applications. Toxicology and carcinogenesis studies were conducted with F344/N rats and B6C3F1 mice of each sex by incorporating

Dyspepsia associated with fluoridated water
The case is presented of 77-year-old woman with a ten-year history of weight loss, dyspepsia, and gastric ulcer resistant to medical management. Within two weeks after she began using a reverse osmosis (RO) unit on her municipal fluoridated (0.85–1.0 ppm F) drinking water source and, without further medication, the patient gained almost full recovery.

[Changes in bone mass and in glucose homeostasis in subjects with high spontaneous fluoride intake]
This paper reports metabolic data of 24 women and two men, 44-66 years old, ex-residents in an area of endemic fluorosis close to Bahía Blanca city. Fasting fluoremias of these subjects (0.5 to 9.2 microM) and daily urinary fluoride excretion (> 60 mumoles/day) are characteristics of zones with endemic fluorosis.

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-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

Fluoride & Insulin
Insulin is a hormone produced by the pancreas that is responsible for maintaining appropriate levels of glucose in the blood. Insulin allows the body’s cells to take up glucose from the blood, and either use it as an energy source or store it as glycogen. Blood glucose levels in diabetics

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
