Description:
In rats subjected to thyroidectomy there was a two- to fourfold increase in cerebral cortex iodothyronine 5'-deiodinase activity within 24 hours. This increase was prevented by thyroxine replacement. The increased cortical 5'-deiodinase in chronically hypothyroid rats was normalized within 4 hours by a single intravenous injection of triiodothyronine. These results indicate that the adult central nervous system can give a very rapid biochemical response to thyroid hormone.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leonard, J L -- Kaplan, M M -- Visser, T J -- Silva, J E -- Larsen, P R -- AM00727/AM/NIADDK NIH HHS/ -- AM18616/AM/NIADDK NIH HHS/ -- AM25340/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1981 Oct 30;214(4520):571-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7291997" target="_blank"〉PubMed〈/a〉
