We examined the effect of anti-triiodothyronine autoantibodies on results of RIA of free triiodothyronine with two commercial kits (Amersham International and Diagnostic Products Corp.). Both methods gave falsely high results because the 125I-labeled analogs used in these RIAs were bound by the autoantibodies.

Three Latin-square trials were conducted to determine the effects of feeding the thyroid depressant propylthiouracil (PTU) on plasma concentrations of thyroxine (T4) and triiodothyronine (T3) in feedlot steers. In trial 1, four steers were fed 0, 1, 2 or 4 mg PTU/kg body weight daily during five 35-d experimental periods. In trial 2, eight steers were fed 0, .5, 1 or 2 mg PTU/kg body weight dai...

Azo dye Reactive Red 195 was selected for decolourization and degradation studies by Georgenia sp.CC-NMPT-T3. Optimization of parameters for dye decolourization was studied under static anoxic condition. Under optimized condition decolourization of Reactive Red 195 by Georgenia sp.CC-NMPT-T3 was found to be 95.93 % at 50 mg/L within five hours in static anoxic condition. The optimum pH and temp...

Thyroid hormone stimulates renal proximal tubule NaCl and NaHCO3 absorption in part by activating the apical membrane Na/H exchanger NHE3. We used a renal epithelial cell line, the opossum kidney (OK) cell, to define the mechanism by which 3,5,3'-triiodothyronine (T3) increases NHE3 activity. T3 stimulated NHE3 activity, an effect that was blocked by inhibition of cellular transcription or tran...

citicoline is a natural substance with neuroprotective and repairing effects. it can also increase the phosphor metabolites in cerebral cortex. regarding the various effects of citicoline on central nervous system, this research aims at studying the effects of citicoline on the thiopental sodium anesthesia. six dogs were anesthetized by intravenous injection of 20 mg ∕ kg of 2.5% thiopental sod...
