Effect of long-term fluoride administration on thyroid hormones level blood in rats
The effect of 2 months fluoride administration (0.1 and 1.0 mg daily/rat) on thyroxine and triiodothyronine level in blood and T3-resin uptake ratio was investigated in rats. In addition, free thyroxine index was calculated from serum thyroxine level and T3-resin uptake ratio. It was found that fluoride administration caused: 1.

Evaluation of thyroid hormones (TSH and T4) in pregnant women exposed to fluoride (F-) in drinking water
Recent research mentioned that exposure during pregnancy can damage the brain of the offspring (Basha P, et al., 2011). It is well know the role of the thyroid hormones in the normal development of the Central Nervous System (CNS) during the pregnancy (Nandi-Munshi and Taplin, 2015). Some evidence indicates that

Effects of protein and calcium supplementation on bone metabolism and thyroid function in protein and calcium deficient rabbits exposed to fluoride
This study was conducted to determine whether feeding a diet containing excess crude protein (CP) or calcium (Ca) for up to 120 days can ameliorate the effects of fluoride (F) intake on bone health and thyroid function observed in rabbits fed a CP- and Ca-deficient diet. Treatment with F increased serum bone Gla

[Effects of endoplasmic reticulum stress-induced apoptosis in thyroid injury caused by fluoride in rat].
Objective: To explore the effects of endoplasmic reticulum stress-induced apoptosis in thyroid injury of rats caused by excessive fluoride intake. Methods: All 40 Wistar rats were randomly divided into four groups, control group, low fluoride group, medium fluoride group and high fluoride group. The rats in control group were fed with

The investigation of effects of fluorosis on thyroid volume in school-age children
Aim To compare the urine iodine, luoride, and to measure thyroid volumes in 10-15-year-old children using ultrasonography, a gold standard in evaluating thyroid volume. Methods A total of 261 children were enrolled into the study group from the 4-8th grades of 3 different primary schools, which were in the zone with high fluoride

Mikhailets (1996): Functional state of thyroid under extended exposure to fluorides
Abnormalities in the thyroid function characterized by a decreased iodine absorption function of the thyroid, a low level T3 syndrome, and a slight increase of the TSH level are observed in cases of chronic fluorine intoxication in the industrial workers.

Fluoride & Goiter
Goitre (aka goiter) is an enlargement of the thyroid gland that in some cases can produce visible swelling in the neck. The main cause of goitre is iodine deficiency. Goitre can also be caused by other things, including hypothyroidism and substances that cause goitre (goitrogens). Since as far back as the

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

Fluoride Exposure Aggravates the Impact of Iodine Deficiency
A consistent body of animal and human research shows that fluoride exposure worsens the impact of an iodine deficiency. Iodine is the basic building block of the T3 and T4 hormones and thus an adequate iodine intake is essential for the proper functioning of the thyroid gland. When iodine intake is inadequate during infancy and

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.
