In a previous report the disappearance curve of plasma radioactivity after intravenous injection of I131-labeled 1-thyroxine was employed to deter- mine the rate of hormone degradation or re- moval in subjects with thyroid disease (1).Thyroxine degradation was slower than normal in untreated myxedema, and faster than normal in 5.0 w -i IL a. z 4c co aJ I~z I--U.a.
