HORMONE LEVELS AND RAIU OF HASHIMOTO‘S DISEASE

The Ievels of hypothysis-thyroid axis hormone and results of RAIU in sixty-six patients with Hashimoto's disease have been determined. According to the diagnostic criterion of thyroid function, fifty-nine patients except seven doubtful patients are classified as normal (42.37%), subclinical hypothyroidism (38.98%), hypothyroidism (11.86%) and hyperthyroidism (6.78%). Dynamic observation proved that the above four conditions can be turned into each other. The values of hormone Ievels in subclinical hypothyroidism and hypothyroidism could be ordered as follows: TSH, TT_4, rT_3, TT_3; TT_3 in prior of TT_4 in hyperthyroidism. The results of RAIU could be represented normal, decrease and increase but with high dispersion and no rule can be found.
