Abstract
The contents of T3, T4, TSH, urine fluoride, and urine iodine in 8-12 year-old children [were measured] in endemic fluorosis areas (water fluoride 3.52 mg/L). The results are: T4 content significantly decreased in the blood. T3 and TSH content was significantly elevated, and there is a positive correlation between the ratio and urine fluoride content, showing a degree of inhibition of the function of children’s thyroids in endemic fluorosis areas, and this inhibition effect may be caused by the long-term exposure of children in the endemic area to a high-fluoride environment.

A trial for improving thyroid gland dysfunction in rats by using a marine organism extract.
Understanding the relation between the environmental stress factors and the hypothalamus-pituitary-thyroid (HPT) axis efficiency can reduce the susceptibility to thyroid diseases. In our study, thyroid dysfunction was induced in female rats by administration of 40 mg Na F/kg.bd.wt/day for a month. Co-administration of the water extract of Arca noae (300 mg/kg.

Study on serum T4, T3 and TSH levels in patients with chronic skeletal fluorosis
A study on the serum T4, T3, and TSH levels was performed in 27 patients with chronic skeletal fluorosis and the data obtained were compared with those of 20 healthy persons. The results showed that serum T4 in the patients was lower than in the controls and TSH was higher.

[Effect of different fluoride and iodine concentration in drinking water on children's dental fluorosis and thyroid function].
Objective: To investigate the effect of different concentrations of fluoride and iodine in drinking water on children's dental fluorosis and thyroid function. Methods: According to different concentration of fluoride and iodine in drinking water, four villages in two counties of Henan province were classified as high fluoride and iodine, high fluoride,

Effect of excessive green tea versus fluoride and caffeine on body weight and serum thyroid hormones in male mice
Green tea is a worldwide used beverage rich in fluoride and caffeine. To study the effect of excessive green tea intake versus fluoride and caffeine on body weight and serum thyroid hormones in male mice. Also, to confirm the effect of excessive green tea intake on thyroid gland was due

y-Aminobutyric acid ameliorates fluoride-induced hypothyroidism in male kunming mice
AIM: This study evaluated the protective effects of y-aminobutyric acid (GABA), a non-protein amino acid and anti-oxidant, against fluoride-induced hypothyroidism in mice. MAIN METHODS: light microscope sample preparation technique and TEM sample preparation technique were used to assay thyroid microstructure and ultrastructure; enzyme immunoassay method was used to assay hormone and

Fluoride's Impact on Thyroid Hormones
Up through the 1950s, doctors in Europe and South America prescribed fluoride for this purpose in patients with hyperthyroidism. (Merck Index 1968). Fluoride was selected as a thyroid suppressant based on findings dating back to the mid-19th century that fluoride is a goitrogen (a substance that can cause goiter). When used as

The Relationship Between Fluoride Exposure & Goitre in South Africa
As a general rule simple goitre, irrespective of the cause, can be very, or fairly, satisfactorily combated by an adequate increase in man's daily iodine intake, except when the enlargement of the gland is due to the ingestion of excessive amounts of fluorine. The only correct solution to fluorine-induced endemic goitre is the removal of this element from the drinking water.

Fluoride, Water Hardness, and Endemic Goitre
Variations in goitre prevalence were found to correlate closely with the fluoride content (p=0-74; P<0-01) and with the hardness (p=0.77; P<0-01) of the water in each village. The effects of fluoride and water hardness seem to be independent.

Is fluoride-induced hyperthyroidism a cause of psychosis among East African immigrants to Scandinavia?
When people with a compensated fluoride-induced hypothyroidism move to a low-fluoride area, the fluoride-induced inhibition of the production of thyroid hormones ceases. In Scandinavia, the dietary intake of iodine is usually quite high due to iodized table salt and easy access to marine fish. Under these conditions, the elevated capacity for production of thyroid hormones may result in hyperthyroidism.

Fluoride Aggravates Thyroid Damage Caused by Excess Iodine Intake
Chinese researchers have found that the combination of excess fluoride with excess iodine caused greater reductions in IQ, or greater increases in goitre than either scenario by itself.
