The formation of tri-iodothyronine and reverse tri-iodothyronine from thyroxine in isolated rat renal tubules.
1. Conversion of thyroxine into tri-iodothyronine and reverse tri-iodothyronine in intact cells was studied with isolated renal tubules prepared by collagenase digestion. 2. Conversion of thyroxine into tri-iodothyronine and reverse tri-iodothyronine increased progressively for at least 90 min. 3. Studies of tri-iodothyronine production from increasing amounts of thyroxine revealed that the thy...

متن کاملChanges in renal tri-iodothyronine and thyroxine handling during fasting.
OBJECTIVE Liver handling of thyroid hormones (TH) has been known to alter significantly during fasting. This study investigates whether renal handling of TH is also changed during fasting. METHODS We measured urinary excretion rates and clearances of free tri-iodothyronine (T(3)) and free thyroxine (T(4)) in healthy subjects prior to and on the third day of fasting. RESULTS During fasting, ...

متن کاملSerum free thyroxine and free triiodothyronine concentrations in pregnancy.
Blood was taken from women in each trimester of pregnancy at routine antenatal visits. Further samples were collected from an age matched control group of euthyroid women taking no medication. Free triiodothyronine and free thyroxine concentrations were measured by direct radioimmunoassay (Amerlex Kit methods, Amersham International, Amersham, Buckinghamshire).2 These free hormone assays use th...
