total T3, iodine uptake and cholesterol of the study group were similar to controls but significantly (P < 0.001) lower than in hyperthyroid patients, except for cholesterol which was higher. In contrast, the basal TSH, increase in TSH after TRH stimulation, and decrease of T4 during T3 ...
Studies on the T3 suppression test by the 24-hour thyroidal 131I uptake in patients with Graves' disease: comparison of the effects of propylthiouracil and... Serum T3, T4 and TSH levels were within normal ranges at one and 3 months after cessation of antithyroid drug. From the results of...
Therefore, if thyrotoxicosis is clinically suspect, and T4 and FTI are normal, the test "T3 -RIA" is recommended (this is not the same test as "T3 uptake," which has nothing to do with the amount of T3 in the patient's serum). T4 is decreased in hypothyroidism and in euthyroid ...
而用L-T4/T3的联合治疗才能有效地缓解.动物研究表明,直接由甲状腺产生的循环T3浓度是重要的.对切除甲状腺鼠的研究表明,要使血 循环和组织中的甲状腺激素正常化并非单一剂量的L-T4所能达到,要达到正常组织T3的含量需要高剂量的L-T4,那样将会导致TSH受抑制,发生亚临床 甲亢的一些组织学表现;而联合使用L-T4/T3治疗...
Perhaps the most striking observation of our study is the striatal T3 deficiency observed in the THRSP OE mice despite normal levels of circulating TSH, T4, and T3, indicating brain-specific T3 deficiency without hypothyroxinemia (low TH levels in the blood) in this transgenic animal model. It...
Thyroid iodine uptake was normal, thus, primary hyper-thyroidism was excluded. Since the patient had normal TFTspreviously, RTHβand FDH were unlikely. The discrepancybetween TSH and T3of the patient led to a suspicion of thedetected interference.The TSH concentrations of the patient before ...
SUMMARYA 16-year-old boy with chronic lymphocytic thyroiditis was noted to have a low free thyroxine (T4) level, low triiodothyronine resin uptake (T3U), and high serum thyrotropin (TSH) values. Unexpectedly, markedly elevated T3 radioimmunoassay (RIA) and T4 (RIA) values, using a double ant...

but still under its influence as shown by the iodine overload, a 'low-T3 syndrome' is observed, this state being characterized by a high total T4, a low free T4, a normal T3 resin uptake, a low total T3, a normal free T3, a high r-T3 and a relative TSH-unresponsiveness to TRH....
