		The researchers determined that "treatment with thyroxine plus triiodothyronine improved the quality of life for most patients."
		The researchers also recommended that the ideal thyroid hormone replacement program for someone without a thyroid gland, or whose thyroid gland is nearly non-functioning, would be "10 µg of triiodothyronine daily in sustained-release form.

		Venous samples measuring total triiodothyronine, free triiodothyronine, total thyroxine, free thyroxine, TSH and thyroglobulin were obtained the day prior to surgery, 10 minutes after bypass and at 1 and 24 hours and 5 and 8 days post surgery.
		A comparison of the group receiving triiodothyronine to the group which did not receive supplementation was performed using repeated measured of analysis of variance.
		Patients who received triiodothyronine had higher free triiodothyronine and total triiodothyronine levels at 1 hour post op but by 24 hours the 2 groups were similar.

		A dose response curve is used to ascertain the concentration of free triiodothyronine in unknown specimens.
		Several drugs are known to effect the binding of Triiodothyronine to the thyroid hormone carrier proteins or its metabolism to T3 and complicate the interpretation of free T3 results (3).

	Postmortem Behavior of Serum Thyroxine, Triiodothyronine, and Parathormone
		Comparison of thyroxine, triiodothyronine, and parathormone levels in antemortem and postmortem sera was done by radioimmunoassay.
		Triiodothyronine was assayed in eleven patients; two levels fell, six rose, and two remained unchanged as late as 17.75 h after death.
		The erratic behavior of triiodothyronine and parathormone after death may be due to conversion from thyroxine or from heterologous forms of parathormone, respectively.

		Triiodothyronine (T3) is transported in serum primarily by thyroxine-binding globulin (TBG), approximately 99.5% of circulating T3 is protein-bound.
		Triiodothyronine contributes significantly to the maintenance of the euthyroid state, and the total T3 level plays an important role in screening for thyroid disease in conjunction with other tests.
		Although triiodothyronine alone cannot be regarded as the best diagnostic parameter of hypothyroidism, it is still more sensitive than thyroxine (T4) for the diagnosis of hyperthyroidism.

		But the researchers found that substituting another thyroid hormone, triiodothyronine, for some of the thyroxine dose led to improvements in mood and in neuropsychological functioning.
		To determine whether patients would benefit from receiving triiodothyronine as well, Bunevicius' team studied 31 women and 2 men who lacked a functioning thyroid and were dependent on thyroxine.
		The authors also detected biochemical evidence that "thyroid hormone action was greater after treatment with thyroxine plus triiodothyronine." But in an editorial, Dr. Anthony D. Toft, of the Royal Infirmary, Edinburgh, Scotland, recommends that physicians should not use thyroxine and triiodothyronine in combination until the study findings are confirmed by additional research.

		The pulse rate and serum sex hormone-binding globulin concentrations were slightly higher after treatment with thyroxine plus triiodothyronine, but blood pressure, serum lipid concentrations, and the results of neurophysiologic tests were similar after the two treatments.
		Although serum concentrations of free triiodothyronine increased in patients and controls taking thyroxine, the difference between the response to placebo and to thyroxine was significant only in the controls.
		Animal studies and a single small clinical trial suggest that a combination of thyroxine and T3 (triiodothyronine), rather than thyroxine alone, may be required for optimal thyroid replacement therapy.

	News - Replacing T4 With Triiodothyronine Improves Cognition And Mood In Hypothyroidism
		In women suffering from hypothyroidism, replacing some of the T4 dose with triiodothyronine improves cognition and mood, a new study shows.
		The authors treated 11 women suffering from autoimmune thyroiditis and 15 females who had been treated for thyroid cancer with either their usual dose of thyroxine (T4) or with a regimen in which 12.5 µg of triiodothyronine (T3) replaced 50 µg T4.

		In patients with hypothyroidism, partial substitution of triiodothyronine [T3] for thyroxine [T4] may improve mood and neuropsychological function; this finding suggests a specific effect of the triiodothyronine normally secreted by the thyroid gland.
		All were conducted with triiodothyronine (T(3)) and a tricyclic antidepressant.
		Five of the six studies found T(3) to be significantly more effective than placebo in accelerating clinical response....the effects of T(3) acceleration were greater as the percentage of women participating in the study increased.

	Medical Dictionary: Triiodothyronine - WrongDiagnosis.com - WrongDiagnosis.com
		In vivo, triiodothyronine enters the nucleus and binds to nuclear thyroid hormone receptors that subsequently bind to thyroid response elements (TREs) located in target genes.
		Receptor binding by triiodothyronine in combination with recruited coactivators results in maximal transcriptional activation after binding to TREs; in general, binding of thyroid hormone receptor alone to TREs leads to repression of gene transcription (NCI04)
		Triiodothyronine : one of the thyroid hormones; an organic iodine containing compound secreted in small amounts by the thyroid gland; most circulating triiodothyroinine is produced by the deiodination of thyroxine in the peripheral tissues.

	Hyperthyroidism: Causes - MayoClinic.com
		Your thyroid gland produces two main hormones, thyroxine and triiodothyronine, that influence every cell in your body.
		The rate at which thyroxine and triiodothyronine are released is controlled by your pituitary gland and your hypothalamus — an area at the base of your brain that acts as a thermostat for your whole system.
		If you don't have enough thyroxine or triiodothyronine in your blood, your TSH blood level will be above normal; if you have too much, your TSH level will fall below normal.

		Apparently, when the thyroid hormone with 3 iodine atoms (T3), known as triiodothyronine, was added to their regular thyroid hormone replacement pill (which is thyroxine, or T4, the thyroid hormone with 4 iodine atoms), people felt much better.
		In this study, 33 patients with severe hypothyroidism were treated alternatively with pure thyroxine (T4) or a lower dose of T4 plus triiodothyronine (T3).
