Effects of Erythrosine on Triiodothyronine, Thyroxine, Thyroid Stimulating Hormone and Thyroid Peroxidase

Study of thyroid hormones free triiodothyronine (FT3), free thyroxine (FT4) and thyroid stimulating hormone (TSH) in subjects with dental fluorosis

OBJECTIVE Apart from its well-known deleterious dental and skeletal effects, fluoride excess can have toxic effects on many other tissues. Fluoride, when in excess, is known to interfere with thyroid gland function. Fluoride-induced thyroid disturbances similar to those observed in iodine deficiency state in spite of adequate iodine intake have been documented. Similar thyroid disturbances in i...

Thyroid Stimulating Hormone Thyroid Stimulating Hormone

Importance of thyroxine in suppressing secretion of thyroid stimulating hormone.

The thyroid uptake of selenium-75-selenomethionine: effect of L-thyroxine and thyroid stimulating hormone.

The uptake of selenium-75-selenomethionine by the thyroid, parathyroid glands, and neck muscles has been estimated in rats using autoradiography ( 1). Selective labeling of the parathyroid glands was demonstrated in animals pretreated with thyroxine and low calcium diet. These qualitative observations led to the recommendation that triiodothyronine be administered to patients prior to parathyro...

Smoking status and changes in thyroid-stimulating hormone and free thyroxine levels during a decade of follow-up: The Tehran thyroid study

Background: Smoking can cause thyroid disorders; the aim of the present study was to investigate the association between smoking status and changes in thyroid hormone levels among adult males during a decade long follow-up of in the Tehran Thyroid Study (TTS). Methods: Data of 895 adult males (smokers=115, non-smokers=691, ex-smokers=89) participants of the TTS without any previously known thy...
