摘　　要：研究了１８２例甲状腺疾病患者治疗前后血清ｒＴ＿３的变化，并与Ｔ＿３、Ｔ＿４等指标比较。结果表明、甲亢未治组和甲亢未控组ｒＴ＿３均明显升高，甲亢已控组ｒＴ＿３下降较慢较迟。甲低未治组ｒＴ＿３明显下降，治疗后Ｔ＿３、Ｔ＿４恢复正常，ｒＴ＿３仍未恢复正常水平。揭示血清ｒＴ＿３的变化反映了机体在甲状腺功能改变时的一种代偿反应。开展ｒＴ＿３检测对甲状腺疾病的诊断和疗效判断有实用价值。The change of rT_3 in 182 patients with thyroidal diseases before , during and afteer treatment isstudied and compared with T_3,T_4. The results show that levels of rT_3 in untreated and unrecovered hy-perthyroidism higher than control values. Serum rT_3 slowly declines in patients with hyperthyredism re-covered after treatment with antithyroidal drugs.Serum rT_3 concentrations fell significantly in patientswith hypothyroidism. However,there is significant difference between treated group with recoveryand normal controls.The mechanism and signi ficance of results are discussed in detail. It is pointedout that the measurement of serum rT_3 may be considered as an effective method for evaluating the thy-roidal function and the effectiveness of medical treatment.
