N/A To evaluate the effectiveness of I-131 in ablation of residual thyroid tissue, we analyzed 350 patients with thyroid cancer who were treated with various doses of I-131 after surgery for thyroid cancer. Two hundred fifty five patients were treated with l.lGBq(30mCi) of I-131 for ablation of remnant thyroid and one hundred seventeen patients received more than 2.8GBq(75mCi) of I-131. We determined the effectiveness of ablation by following I-131 whole body scan. Absent visible uptake or minimal uptake in thyroid tissue were considered as successful ablation. Of 255 patients who received doses of 30mCi I-131 therapy, 131 patients(51%) showed successful ablation of residual thyroid tissue with 2.6±1.7 times of I-131 therapy. Of 117 patients who received doses of the more than 75mCi I-131, 84 patients(72%) had successful remnant thyroid ablation with 1.6±1.1 times of I-131 therapy. According to the extent of surgery, successful ablation rates were 78%, 62%, 54%, 33% in patients who underwent total thyroidectomy, subtotal thyroidectomy, lobectomy and isthmectomy, lobectomy or tumorectomy, respectively. This study showed that ablation of remnant thyroid after surgery with 30mCi I-131 was successful only in 50%. Therefore, in cases of patients with high risk for recurrence, we recommend high dose I-131 for ablation of remnant after total thyroidectomy.

N/A Polyglandular antoimmune (PGA) syndrome designates endocrine dysfunction involving two or more glands on the basis of autoimmune mechanisms. There are 3 types of PGA syndrome and their etiology or pathogenesis is still not completely understood. We report here a case of polyglandular autoimmune syndrome manifesting insulin-dependent diabetes mellitus, hyperthyroidism and myasthenia gravis, which met the criteria of type III PGA syndrome. HLA-DR4 & -DRw8 were positive and so was the thyroid antimicrosomal antibody. We think that upon further study, additional cases of this syndrome could be found.

316L stainless steel welding tube was electrolytically polished and the inner surface characteristics of the tube were tested. Electro-polishing variables such as current, voltage, concentration of electrolyte and electro-polishing time were changed to seek for optimum condition. These makes a optimum conditions for the electro-polishing as 4000A, 9V, 1.7 specific gravity of electrolyte, 30minute of electro-polishing time. It resulted as the surface roughness of Ra< 0.25μm. XPS resulted as the ratio of CrO/FeO equals or more to 3/1. AES resulted as the thickness of CrO film of 38Å. DTA resulted as the tube did not react with N2, H2 and O2 gas till 1073K. As summarize above results, the electro-polished 316L stainless steel welding tube satisfied the conditions to apply as a pipeline for semi- conductor production facility and clean room.
