  • Hyperplastic nodules of thyroid parafollicular cells (C cells) in rats induced by prolonged low dose ingestion of NaF

    In rats which received drinking water containing 0, 3, 6, 12, 25 ppm NaF (F-) for 20 months, hyperplastic nodules, consisting of thyroid parafollicular cells (C cells) appeared in all F- groups, particularly in those which received 12 and 25 ppm. By immuno-histochemistry and electron microscopy, both calcitonin and characteristic

  • 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.

  • Fluoride ingestion and thyroid function in children resident of naturally fluoridated areas - An observational study.

    Background: Literature shows association between systemic fluorides with water fluoride level above 3ppm and endocrine disorders especially related to thyroid. Aim & Objectives: To estimate serum T3, T4, TSH, Fluoride levels among children with normal nutritional status and optimal iodine intake, residing in three different ranges of drinking water fluoride levels

  • 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.

  • NRC (2006): Fluoride's Impact on the Thyroid Gland

    Several lines of information indicate an effect of fluoride exposure on thyroid function. It is difficult to predict exactly what effects on thyroid function are likely at what concentration of fluoride exposure and under what circumstances.

  • 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

  • Fluorine in the Aetiology of Endemic Goitre

    The distribution of endemic goitre in the Punjab and in England is related to the geological distribution of fluorine and to the distribution of human dental fluorosis (mottled enamel). Inquiry showed the presence of dental fluorosis among school-children in two areas of Somerset where two previous observers had recorded a high incidence of goitre, and the absence of dental fluorosis in an adjoining area selected as control where endemic goitre was absent.

  • 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.
