摘要
In order to investigate the relationship between concentration of methimazole(MMTand clinical curative efficacy,the concentration of MMI in Plasma and thyroid tissue was measuredin 26 patients with Graves' disease by HPLC,meanwhile their T-lymphocyte subsets,thyroid autoimmune antibodies and serum immunoglobulin were also measured.The results showed: ① The plasmaand intrathyroid concentrations of MMI of recovery group were much higher than those of unrecovery group(P<0.001).② The hardness of thyroid had a significant effect on the concentration ofMMI in thyroid.③Plasma concentration of MMI in the patients with no or 1 ̄2-degree enlargement of thyroid was much higher than that in the patients with 3-degree enlargement of thyroid(P<0.001). In addition, the plasma concentration of MMI in the subjects with soft thyroid was mudhigher than that in those with hard thyroid(P<0.001).Our study demonstrated that MMI playeda role in the immune supression of thyroid autoimmune antibodies and the immune regulation of Tand B-lymphocytes.Effective MMI concentration in the plasma and intrathyroid is the key of thesuccessful clinical treatment and correlates with the size and hardness of thyroid.
