Abstract
Objective: To study the effect of excessive fluoride intake on the function of pancreatic islet’s B cells.
Methods: We performed x-rays, determined the [F] in the urine, conducted OGTT insulin and C-peptide releasing tests in the serum, and analyzed the drinking water quality of the exposed group and control group.
Results: (1) The [F] in drinking water and the geometrical mean of the [F] in the urine of the people of the exposed group were higher than those of the control group. (2) The fasting blood glucose concentration and the peak value after oral glucose in the exposed group were higher than those of the control group. The peak value was found later in the exposed group than in the control group. (3) The detectable rate of Diabetes and IGT in the exposed group was higher than that in the control group. (4) The blood-insulin and C-peptide in the exposed group were lower than in the control group, although the peak value after oral glucose was found later in the exposed group.
Conclusions: Excessive fluoride can do much harm to the function of the pancreas islet B cells and the effects change with the degree of fluorosis.

[Activities of some enzymes and concentration of ammonia in serum of rats with fluoride hyperglycemia]
The study was done in 30 one-month-old Wistar FL rats divided into one control and two study groups of ten animals each. Hyperglycemia was induced with sodium fluoride in water at a concentration of 50 or 100 mg/L during four months. Control animals received distilled water. We observed significantly (p

Fluoride exposure aggravates the testicular damage and Sperm Quality in diabetic mice: protective role of ginseng and banaba
Fluoride toxicity is known to pose infertility in fluoride-intoxicated animals as well as in people residing in fluoride endemic zones. The present study addresses the degree of impairments caused due to co-exposure of high fluoride toxicity in diabetic mice. Swiss mice, Mus musculus, were subjected to fluoride toxicity by providing

[Chronic fluoride intoxication as a risk factor for the development of atherosclerosis]
In workers employed in the aluminum industry, the main harmful production factor is exposure to fluoride salts, which can cause chronic fluoride intoxication. For the assessment of the impact of chronic fluoride intoxication on the development of atherosclerosis, we conducted a comprehensive survey of 87 aluminum-metal makers with chronic fluoride

Low-level fluoride exposure increases insulin sensitivity in experimental diabetes
The effect of chronic fluoride (F) exposure from the drinking water on parameters related to glucose homeostasis was investigated. Wistar rats were randomly distributed into 2 groups (diabetic [D] and nondiabetic [ND]; n = 54 each). In D, diabetes was induced with streptozotocin. Each group was further divided into 3

Mathematical model of glucose-insulin homeostasis in healthy rats.
According to the World Health Organization there are over 220 million people in the world with diabetes and 3.4 million people died in 2004 as a consequence of this pathology. Development of an artificial pancreas would allow to restore control of blood glucose by coupling an infusion pump to a

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
