The pituitary gland secretes thyrotropin ( TSH; Thyroid Stimulating Hormone ) that stimulates the thyroid to secrete thyroxine ( T4 ) and, to a lesser degree, triiodothyronine ( T3 ).
32.
In health, the thyroid gland predominantly secretes thyroxine ( T 4 ), which is converted into triiodothyronine ( T 3 ) in other organs by the selenium-dependent enzyme iodothyronine deiodinase.
33.
A TFT panel typically includes thyroid hormones such as thyroid-stimulating hormone ( TSH, thyrotropin ) and thyroxine ( T4 ), and triiodothyronine ( T3 ) depending on local laboratory policy.
34.
Both iopanoic acid and ipodate sodium are potent inhibitors of thyroid hormone release from thyroid gland, as well as of peripheral conversion of thyroxine ( T 4 ) to triiodothyronine ( T 3 ).
35.
The remission rates based on the HAM-D in the combination strategy were 15.9 % for lithium and 24.7 % for triiodothyronine, but the difference was not statistically significant.
36.
This butterfly-shaped gland at the base of the neck makes key hormones _ thyroxine ( T4 ) and triiodothyronine ( T3 ), which affect metabolism, growth, nerves, muscles and circulation.
37.
They contain a mixture of thyroid hormones : T4 ( thyroxine ) & T3 ( triiodothyronine ), in the proportions usually present in pig thyroids ( approximately 80 % T4 and 20 % T3 ).
38.
Administration of triiodothyronine ( T3 ) in the diet, from day of hatch until 8 weeks of age, to sex-linked dwarf chickens stimulates growth but can not fully restore a normal growth rate.
39.
In collaboration with Robert J . Ryan, M . D ., and William E . Mayberry, M . D ., he developed the first RIA to measure triiodothyronine ( T3 ) in human serum.
40.
They can be used in the treatment of patients with severe thyrotoxicosis ( thyroid storm ) and significant morbidity ( e . g ., myocardial infarction, or stroke ) for rapid control of elevated plasma triiodothyronine concentrations.
