【 摘 要 】

References(18)Cited-By(2)In order to determine whether thyrocyte responsiveness to TSH is correlated with post-operative thyroid status, thyrocytes obtained from 51 patients with Graves' disease were cultured for 3 days. This was followed by culture with 10mU/mL of TSH (TSH group) or without TSH (control group) for 3 additional days. On the 8th culture day, the amount of thyroglobulin (Tg) secreted into the culture medium was assayed and the Tg ratio (amount of Tg from the stimulated group/amount of TG from the control group) was calculated. Log10 (the Tg ratio) was used for the statistic study. The post-operative status of the patient was determined based mainly on the serum concentration values of free T3 and T4 obtained between 5 and 16 months after surgery. Multivariate analysis revealed that among age, gender, TSH-binding inhibitory immunoglobulin (TBII) obtained before the surgery, estimated weight of the thyroid gland remnant, and Log10 (Tg ratio), only Log10 (Tg ratio) was statistically significant (P=0.008). When the Log10 (Tg ratio) value was small, most patients showed signs of as post-operative hypothyroidism, and as the value became larger as the number of euthyroid and/or hyperthyroid patients increased.
