[Effect of 3,3',5' triiodo-L-Thyronine (rT3) on the serum concentration of thyroid hormones in rats]

Abstract50, 100 or 150 micrograms/100 g body weight/day of very pure 3,3',5' triiodo-L-thyronine (rT3), obtained from a new synthetic method, was intraperitoneally administered in male Wistar rats for 5 weeks. Serum total thyroxine (T4), free thyroxine (FT4) and total 3,5,3' triiodo-L-thyronine (T3) concentrations were increased with all the doses of rT3. Free T3 (FT3) was also but non-significantly elevated. Different assumptions are put forward in order to explain this rT3 effect.
