Triiodothyronine administration before partial hepatectomy increased the activity of mitochondrial glycerophosphate cytochrome c reductase. The enzyme activity was further activated after partial hepatectomy during the regenerative process. Our findings showed that: a) the increase of glycerophosphate cytochrome c reductase induced by triiodothyronine was further potentiated by the regeneration...

SABURADA, T., DEMURA, R., ONODERA, S., SAITO, S. and MATOBA, N. A case of triiodothyronine-secretor with hypometabolism.. Tohoku J. exp. Med., 1973, 110 (4), 319-327-A 35-year-old man had vague complaints as headache, vertigo, nausea and fatigability. His face was slightly edematous but ocular symptoms or goiter were not observed. BMR and serum BEI were low; thyroidal 24-hours 131I-uptake was l...

An evaluation of a heterogeneous enzyme immunoassay for determination of triiodothyronine in serum (Enzymun-Test T3, Boehringer Mannheim) is presented. The enzyme immunoassay was compared with the laboratory routine radioimmunoassay. The precision of both assays was satisfactory at triiodothyronine concentrations between 1.0 and 8.0 nmol/l (coefficients of variation from day to day less than or...

Severe constipation and hypothermia progressing to hypothermic coma are known complications of myxoedema. The occurrence of hypothermia is recognized to be an indication for urgent treatment with the most rapidly acting thyroid preparation available, l-triiodothyronine. There are only two cases of hypothermic myxoedema coma which have been successfully treated with triiodothyronine reported in ...

background: polycyclic aromatic hydrocarbons (pahs) such as naphthalene (nap) are organic pollutants that have spread widely in littoral marine ecosystems. we aimed to study the effect of acute and prolonged exposure to naphthalene (nap) on plasma cortisol and thyroid levels in mature and immature liza klunzingeri mulet. methods: in acute stress experiment, the treatment group received 2μl g-1 ...

the aim of this study was to evaluate total iodine, triiodothyronine (t3) and thyroxine (t4) status in the blood serum of holstein cows on six farms in central iran. total iodine, t3 and t4 concentrations were measured in 90 blood serum samples (15 per farm). mean concentrations of total iodine (38.80 ± 1.52 µg/l) and t3 (1.57 ± 0.10 nmol/l) were lower but the mean concentration of t4 (45.60 ± ...

Purpose: To investigate the effect of triiodothyronine (T3) in odontoblast differentiation apical papilla stem cells, and mechanism action involved.
 Methods: Apical unclosed permanent molars extracted from patients due to orthodontics impaction were selected. The teeth cultured isolation stage SCAP cells. cells exposed different concentrations T3. effects ERK p38 MAPK signaling pathways o...

In this communication, we provide evidence that proliferation of transplantable Morris hepatoma 7777 might to some extent be regulated by triiodothyronine and/or a specific serum protein, the levels of which are correlated with levels of triiodothyronine. The protein has an estimated molecular weight of 80,000 and migrates as one band on polyacrylamide gel electrophoresis. In normal rats, this ...

A thyroid suppression test is suggested which relies on the change in concentration of serum thyroxine as the index of thyroid response to the administration of triiodothyronine. The test has been carried out in 16 healthy volunteers and in 27 patients referred for routine suppression tests. This index appears to be sensitive and safe and results in a reduction in the required dosage of triiodo...
