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...

We have investigated the thermodynamic properties of triiodothyronine (T3)-solubilized hepatic nuclear receptor interaction. These studies revealed that the equilibrium constant was markedly dependent on temperature and van't Hoff plots revealed a significant deviation from linearity. Both enthalpy and entropy changes decreased with increasing temperature such that at 37 degrees C both were neg...

Myoglobin acts as an oxygen store and a reactive oxygen species acceptor in muscles. We examined myoglobin mRNA in rat cardiac ventricle and skeletal muscles during the first 42 days of life and the impact of transient neonatal hypo- and hyperthyroidism on the myoglobin gene expression pattern. Cardiac ventricle and skeletal muscles of Wistar rats at 7-42 days of life were quickly removed, and ...

conclusions no significant variance was observed among patients underwent for cardiac catheterization, stemi, nstemi, unstable angina, and atrial fibrillation with respect to ft4, ft3, and tsh levels during coronary care unit hospitalization based on their profile data. results excluding those taking thyroid hormone preparations, 76.7% of patients admitted with acute coronary heart disease (st-...
