FIGURE 1. Total 131I activity and PB131I activity per liter of serum on day 0 after radioiodine therapy in patients with nodular goiter. (A and B) Nine patients were pretreated with 0.01 mg of rhTSH (A), and 9 with 0.03 mg of rhTSH (B). The results for each rhTSH group were compared with those for 9 control patients. Mean value + SEM is given.
= total 131I activity in rhTSH-pretreated patients;
= total 131I activity in control patients; = PB131I activity in rhTSH-pretreated patients;
= PB131I activity in control patients.
