Clinica Chimica Acta, 1977
The possibility that lithium affects the conversion of thyroxine to 3,5,3"-triiodothyronine and 3,3',5'-triiodothyronine (reverse triiodothyronine) was studied by measurement of the serum concentractions of these parameters in five patients during the first week of lithium therapy. In three patients there was a decrease in serum thyroxine concentration

Evidence That Triiodothyronine and Reverse Triiodothyronine Are Sequentially Deiodinated in Man*
The Journal of Clinical Endocrinology & Metabolism, 1978We have demonstrated that in patients given a single iv injection of T3, rT3, or, to a lesser extent, T4, all labeled with 125I in the outer or phenolic ring, chromatography of serum on columns of Sephadex G-25 superfine revealed the presence of a labeled material, separate from the administered hormone and from both iodide and iodoprotein.

Reverse triiodothyronine in the chicken
Life Sciences, 1977Abstract Reverse triiodothyronine (rT 3 ) which is apparently a product of 5-monodeiodination of thyroxine (T 4 ) at the periphery, was measured in 199 chickens of various strains. rT 3 was virtually absent in young birds (less than 1 week to 8 weeks of age) in marked contrast to the elevated rT 3 levels found in human and other mammalian neonates.

Triiodothyronine in Cardiac Surgery
Thyroid, 1997Thyroid hormones have profound cardiovascular effects. Chronic hypothyroidism is associated with cardiovascular abnormalities that include diminished cardiac output and increased systemic vascular resistance. Acute hypothyroidism, frequently referred to as the "euthyroid sick syndrome," is present in diverse clinical situations such as brain death ...

Triiodothyronine and Brain Excitability
Epilepsia, 1990Summary: We investigated mechanisms involved in thyroid hormone action on brain excitability. The effect of acute exposure of triiodothyronine (T3) to rat hippocam‐pal slices in vitro was studied. No significant changes could be detected in prevolley, field excitatory postsynaptic potentials (fEPSP) and population spike amplitude, while there was a ...

Effect of Triiodothyronine on Radiosensitivity
Nature, 1958REDUCTION in metabolic rate has been shown to reduce radiosensitivity, but the effect of an elevated metabolic rate has not been well established. Similarly, anoxia induced by various means reduces radiosensitivity. In recent years, the reverse of this phenomenon has been applied in the attempt to increase the radiation response.

TRIIODOTHYRONINE (T3) TOXICOSIS
Archives of Internal Medicine, 1972To the Editor. —On reading the article, "Triiodothyronine (T 3 ) Toxicosis," by the Mayo Clinic group in the October issue ( Arch Intern Med 128 :529-534,1971), I was disappointed not to find reference to the discovery of T 3 by Gross and Pitt-Rivers. 1 Such amenities are too often neglected in our scientific presentations.
