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.展开更多
