To examine serum levels of sICAM 1 from normal controls and patients with thyroid diseases (simple goitre, Graves’ disease or Hashimoto’s thyroiditis) with 125 Ⅰ sICAM 1 RIA established in our lab Methods Using 125 Ⅰ sICAM 1 RIA, serum sICAM 1 levels of 400 healthy individuals as the normal group and 1020 patients with simple goitre (SG), Graves’ disease (GD) or Hashimoto’s thyroiditis (HT) were examined for a comporative chinical study Results The serum level of sICAM 1 ( ±s ) in the normal group was 168 43±36 23 μg/L There was no significant difference between the normal and SG groups ( P 】0 05), whereas the serum levels of sICAM 1 in autoimmune thyroid diseases (GD or HT) were higher than those in the normal or SG groups ( P 【0 05, respectively) After GD patients received one of three medical treatments, their serum sICAM 1 levels decreased ( P 【0 05) After GD patients were treated and their thyroid function decreased to normal, their serum sICAM 1 levels were lower than those in relapsed GD patients ( P 【0 05) Conclusions sICAM 1 RIA can be used to examine autoimmune thyroid diseases Serum levels of sICAM 1 can be used as a parameter in diagnosing autoimmune thyroid disease and in evaluating the effects of therapy, drug administration or relapse in GD 展开更多
