L-triiodothyronine and L-reverse-triiodothyronine generation in the human polymorphonuclear leukocyte.
Extrathyroidal monodeiodination of l-thyroxine (T(4)) is the principal source of l-triiodothyronine (T(3)) and l-reverse-triiodothyronine (rT(3)) production. To define some of the cellular factors involved, we examined T(3) and rT(3) generation from added nonradioactive T(4) in human polymorphonuclear leukocytes, using radioimmunoassays to quantify the T(3) and rT(3) generated. Under optimum in...
متن کامل[Serum ratios of triiodothyronine to thyroxine and reverse-triiodothyronine in Graves' disease and destruction-induced thyrotoxicosis].
In order to determine the frequency of thyroxine (T4) toxicosis and study the possibility of usefulness for differentiation between thyrotoxic Graves' disease and destructioninduced thyrotoxicosis, the serum concentrations of T4, triiodothyronine(T3), reverse T3 (rT3), and T4-binding globulin (TBG) and the values of T3-uptake and radioactive iodine uptake (RAIU) were measured, and free, T4 inde...
متن کاملEvaluation of serum triiodothyronine and adjusted triiodothyronine (free triiodothyronine index) in pregnancy.
We measured serum thyroxine (free and total), triiodothyronine (free and total), thyroxine-binding globulin, and triiodothyronine uptake by talc in 97 normal men and 50 pregnant women. Mean serum thyroxine and triiodothyronine concentrations were higher in the pregnant subjects (104 vs. 78 mug/liter and 1.69 vs. 1.30 mug/liter) because of a higher mean thyroxine-binding globulin concentration (...
متن کاملMonodeiodination of thyroxine to 3, 5, 3'-triiodothyronine and to 3, 3', 5'-triiodothyronine in isolated dog renal cortical tubuli.
Monodeiodination of T4 to T3 and rT3 in the intact cells of dog renal tubuli and glomeruli was investigated. The tubuli and glomeruli were obtained by a sieve method. T4 (2 micrograms/ml) was incubated in Tris-HCl buffer, pH 7.5, with renal cells (180 micrograms protein/ml) and 5 mM DTT for 1 h at 37 degrees C and the T3 and rT3 generated during incubation were measured by specific radioimmunoa...
متن کاملPeripheral serum thyroxine, triiodothyronine and reverse triiodothyronine kinetics in the low thyroxine state of acute nonthyroidal illnesses. A noncompartmental analysis.
The low thyroxine (T(4)) state of acute critical nonthyroidal illnesses is characterized by marked decreases in serum total T(4) and triiodothyronine (T(3)) with elevated reverse T(3) (rT(3)) values. To better define the mechanisms responsible for these alterations, serum kinetic disappearance studies of labeled T(4), T(3), or rT(3) were determined in 16 patients with the low T(4) state and com...
