[Effect of mild and moderate excessive iodine supplementation on thyroid function and morphology in non-iodine deficiency rat model].

Objective: To study the effect of moderate and mild iodine excess on thyroid function and morphology in non iodine deficiency Wistar rats.

Methods: Serum thyroid-stimulating hormone (TSH) was measured with solid phase radioimmunoassay (IRMA) and serum total T(4) (TT(4)), TT(3), reverse T(3) (rT(3)) and thyroid TT(4) with radioimmunoassay (RIA). Cer-Arsenite colorimetric method was used to measure median urinary iodine (MUI).

[Correlation between serum thyroglobulin and thyroid stimulating hormone in populations with non-toxic goiter].

Objective: To investigate the correlation between serum thyroglobulin (Tg) and thyroid stimulating hormone (TSH) in populations with non-toxic goiter.

Methods: Thyroid ultrasonography was conducted, and determination of serum triiodothyronine (FT3), thyroxin (FT4), Tg, thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TGAb) and TSH, and urine iodine were carried out among 609 persons with an average age of 35.4 in Panshan county, a mild iodine-deficient area in Liaoning province, and 1136 persons aged 39.

[An epidemiological study on factors affecting serum thyroglobulin levels].

Objective: To investigate the effects of several factors affecting serum thyroglobulin (TG) levels among people aged 14 or more.

Methods: We selected Panshan with median urinary iodine (MUI) 83.45 micro g/L as a deficient iodine intake community, Zhangwu with MUI 242.
