Abstract
Forty seven-week-old male castrated Wistar rats were randomly divided evenly into a control group and a fluoride (F) group. The latter was given a single dose of NaF from a solution containing 1.0 mg F ion/kg bw, administered by gavage. After 30 min, the following experiments were performed: intravenous insulin tolerance test (0.75 U/kg bw) and determination of the insulin receptor substrate (pp 185–IRS-1/IRS/2) tyrosine phosphorylation status. The acute treatment with NaF promoted increased blood glycemia, but there were no significant changes in the insulin sensitivity and in the pp185 tyrosine phosphorylation status in the muscular or in the white adipose tissues.

Effect of sodium fluoride on bone biomechanical and histomorphometric parameters and on insulin signaling and insulin sensitivity in ovariectomized rats
Osteoporosis is a systemic disease characterized by bone degradation and decreased bone mass that promotes increased bone fragility and eventual fracture risk. Studies have investigated the use of sodium fluoride (NaF) for the treatment of osteoporosis. However, fluoride can alter glucose homeostasis. The aim of this study was to evaluate

Antihyperglycemic and antihyperlipemic effects of Mangifera Indica L. in fluoride induced toxicity.
A chronic intake of fluoride through food and drinking water is also known to cause hyperglycemia and dyslipidemia besides fluorosis. The present study deals with the effects of fluoride (100 ppm) induced hyperglycemia and dyslipidemia and the alleviatory potential of Mangifera indica L. on the carbohydrate and lipid profiles in

Reversible impairment of glucose tolerance in patients with endemic fluorosis. Fluoride Collaborative Study Group.
Endemic fluorosis is a condition resulting from prolonged ingestion of drinking water which contains excess fluoride. Studies on rats have suggested that fluoride toxicity may produce glucose intolerance and abnormalities in insulin secretion. We studied glucose and insulin profiles following an oral glucose load in patients with endemic fluorosis. Twenty-five

Toxicity of fluoride to diabetic rats
SUMMARY: Wistar rats were given 20 ppm fluoride in drinking water, or single administration of 115 mg/kg alloxan i.m. to induce diabetes, or single administration of 115 mg/kg alloxan i.m. followed by 20 ppm fluoride for 31 days. Blood sugar level increased in rats given alloxan and alloxan + fluoride.

Therapeutic benefits of glibenclamide in fluoride intoxicated diabetic rats.
To examine its antidiabetic potential in fluoride (F) intoxicated rats, the anti-diabetic drug glibenclamide was administered for 4 weeks to diabetic rats and to diabetic rats exposed to 100 mg NaF/L in the drinking water. In the F treated rats there was a significant reduction in plasma glucose, plasma and

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

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
