DeiodinaseSlc16a2Thyroid hormoneType I deiodinaseThe Allan-Herndon-Dudley syndrome is a severe psychomotor retardation accompanied by specific changes in circulating thyroid hormone levels (high T3, low T4). These are caused by mutations in the thyroid hormone transmembrane transport protein monocarboxylate...
Scatchard plot analyses for the antibodies against T3 and T4 showed high affinity constants for these hormones. With adequate l-thyroxine therapy, an appropriate decline in serum TSH to normal was achieved. It is concluded that where RIA determinations of T3 and T4 are inconsistent with other ...
T4 and T3 levels were high during pregnancy and remarkably elevated in mole. TBG levels were 49.0 +/- 5.1/micrograms/ml in 3rd. trimester, which were 2.6 times higher than non-pregnant women and 38.4 +/- 8.4 micrograms/ml in mole. Res-O-Mat T3 values distributed within normal levels in...
SHBG levels are usu- ally elevated in thyrotoxicosis and have been reported to be normal in a few patients with generalized resistance to thyroid hormone (GRTH) [5,6]. Also, a significant body of evidence exists showing a positive correlation between the serum levels of T3, T4 and ferritin...
The high T3 and T4 blood serum values in the animals treated with L-T4 decreased, when the treatment was completed, from October 5 to November 24, before returning to the levels of the untreated animals in December. The highest average epidermis height in the L-T4 treated animals was in ...
T3与各种蛋白的亲和力小得多,主要与TBG结合,但只有T4结合量的3%,大部分T3以游离形式存在。 当甲状腺激素进入血液后会缓慢释放。 Because of high affinity of the plasma-binding proteins for the thyroid hormones, these substances—in particular, thyroxine—are released to the tissue cells slowly. Half the...
Circulating thyrotropin titers were measured in 5 patients with Graves' disease in whom thyroid function persisted at normal or supranormal levels after total hypophysectomy. Serum TSH levels were found to be in the normal range in thyrotoxic individuals before pituitary ablation. In all cases, blood...
Aims: To evaluate the effect of addition of T3 to L-T4 treatment in children with congenital hypothyroidism (CH) who have inappropriately elevated thyroid-stimulating hormone (TSH) levels despite high normal serum T4 levels on L-T4 treatment. Methods: Ten children (age 7.1 ± 2 years...

your liver. And high estrogen makes a high TBG thyroid-binding globulin, which binds onto thyroid hormones. This form isn’t active so your thyroid levels sink even further even when your thyroid is doing everything it’s supposed to be doing and your lab tests may appear to be normal!
