Purpose: The nonrecurrent laryngeal nerve(NRLN) is a rare anomaly that is associated with the developmentally aberrant subclavian artery. Although rare on the right side and exceptional on the left, an aberrant nonrecurrent pathway for RLN represents a major surgical risk. Three course variations of right NRLN can be distinguished: descending(type I) , horizontal(type II), ascending(type III). This study is performed to characterize the variations of NRLN, associated vascular anomaly, and proper surgical methods for preventing nerve damage. Materials and Methods: Between January 1998 and March 2006 3,381 thyroidectomy were performed at our institution, and during these operations a nonrecurrent laryngeal nerve was observed in 13 cases (0.38%). There were 1 men and 12 women with a median age of 48 years(range 28-57). All of them are identified on the right side. Results: In all cases, there were no clinical symptoms observed preoperatively. The nerve anomaly was diagnosed preoperatively in only one case. There were type I variations of right RLN in 2 cases and type II variations in 11 cases. The retroesophageal aberrant right subcalvian artery; no innominate(brachiocephalic) artery was found and the right common carotic artery was arising directly from the aortic arch, was seen in 12 cases. A vocal cord palaysis caused by NRLN damage during operation was observed in one patient(7.6%) , where the nerve was close to the superior thyroid artery. No other complications were noted. Conclusion: It can be possible to predict NRLN from signs associated with the vascular anomaly; clinical symptoms or imaging studies. When an vascular anomaly is not detected preoperatively, overlooking possibility of NRLN may lead to severe operative morbidity. Hence, It is most important to identify all the thyroid structures carefully during thyroid surgery and to be aware of the possibility of anatomic variations of RLN.

Objective: This is aprospective clinical case study that includes the administration of Ahnjeonbaekho-tang (AJBHT) to patients who have suffered from Graves' disease for the 8 weeks of the clinical research. Methods: Without administration of an antithyroid drug, AJBHT was administered 3 times a day for 8 weeks. In Case 1, AJBHT without modification was administered and in Case 2, in accordance with the patients' symptoms, a dose of Gypsum Fibrosum was increased by 4g from the beginning of week 2, and further increased by 16 g, for a total of 20 g between week 6 and week 8. Body mass index (BMI), thyroid function test (TFT), thyroid autoantibody test, complete blood cell count (CBC), and blood chemistry (BC) tests were conducted at an interval of 4 weeks, for a total of 3 times during the study. The clinical manifestations, a spectrum of symptoms of the patients, was observed by Wayne's Index, Euro-QOL-5 Dimension (EQ-5D), and Perceived Stress Scale (PSS). Results: In both cases, an acceptable significance of reduction of value in T3, fT4, Thyroid stimulating antibody (TSAb) and Thyroid stimulating hormone receptor antibody (TSH-R-Ab) was observed. After treatment, in TFT, T3 decreased by 31.66%, fT4 decreased by 32.82% in Case 1, and T3 decreased by 43.42%, and fT4 decreased by 37.32% in Case 2. In the thyroid autoantibody test, TSAb decreased by 7.59%, and TSH-R-Ab decreased by 53.19% in Case 1, and TSAb decreased by 33.45%, TSH-R-Ab decreased by at least 7.75% in Case 2. Besides this, there was a decreasing trend of Wayne's index, and a loss of typical symptoms of hyperthyroidism also declared the efficacy. Conclusion: From these results, AJBHT is very effective in the regulation of TFT and improving the symptoms of hyperthyroidism, and is also expected to be an effective alternative to antithyroid drugs for patients who have side effects or drug intolerance.

Objectives: Papillary microcarcinoma of the thyroid was evaluated as to the effectiveness of diagnostic modalities, lymphatic spread pattern, and therapeutic decision according to tumor size. Material and Methods: We retrospectively analyzed a clinicopathologic findings of 72 papillary microcarcinoma patients who were treated at the over 11 years between 1985 and 1995. The authors divided papillary microcarcinoma of the thyroid into two subgroups according to tumor size: $0{\leqq}5mm$ and $5<0{\leqq}10mm$. An analysis including age and gender distribution, diagnostic tools(thyroid sonogram, thyroid scan, thyroid function test, fine needle aspiration cytology, frozen section), pathological examination of lymphnode, and surgical procedures was carried out in each subgroups. Results: The carcinoma of smaller than 5mm were found in 32 patients, and of 6 -10mm were in 40 patients. The average age of patients was 45years and all of them were female. Cold nodules on thyroid scan were noticed in 53 patientss and normal findings were in 15 patients. Suspicious malignant lesions(fine calcification, solid mass, irregular margin) on thyroid sonography were detected in 23 patients and the sonography was more useful in detecting $0{\leqq}5mm$ small sized lesions than other diagnostic methods. FNAC were performed in 17 patients, and 7 patients were diagnosed as having thyroid papillary cancer. But diagnotic rate in $0{\leqq}5mm$ small sized lesions was very low(one of eights).Frozen section were performed in all patients, among these 15 patients were diagnosed as being benign diseases and false negative rates were higher in $0{\leqq}5mm$ small sized lesions than in $5<0{\leqq}10mm$ sized lesions(p-value<0.006). Only thyroidectomies were performed in 24 patients and thyroidectomy with node dissections in 48 patients. The lymphnode metastatic rates were much higher in multifocal lesions(61.5%) than in single lesion. The incidence of cervical lymphnode metastasis was 19.4% in $0{\leqq}5mm$ sized lesions and 47.9% in $5<0{\leqq}10mm$ sized lesions. Postoperative management were performed with TSH suppression therapy(T4, synthroid) in all patients and RI therapy in 29 patients. Conclusion: On the basis of our study, improved preoperative diagnostic tools for papillary microcarcinoma of the thyroid was helpful in the choice of surgical treatment. As a result of techninological progress(ultrasonography, FNAC), the pencentage of the discovery of papillary microcarcinoma has been increased. The thyroid ultrasonography was useful in detecting small sized lesions($0{\leqq}5mm$), but FNAC may not be beneficial in detecting small sized lesions($0{\leqq}5mm$). In the surgical procedure, thyroid lobectomy alone should be avoided because of the high rate of bilaterality and multifocality.

Objective : This study was performed to investigate the antineoplastic effect of Astragalus membranaceus, Angelica gigas, Rhus verniciflua Stokes and Trichosanthes kirilowii on SNU-80 anaplastic thyroid carcinoma cell line. Method : We examined whether our herbal medicines decreases cell growth rate of SNU-80 using MTT assay. We performed western blot analysis to verify that our herbal medicines induces apoptosis via caspase-dependent mechanism. We also performed wound healing assay and transwell invasion assay to investigate whether our herbal medicines affects the migration and invasion of anaplastic cancer cells, SNU-80. We also carried out ELISA assay to know our herbal medicines suppresses the expression of proinvasive molecules, such as VEGF and MMP-2 secreted from SNU-80. Results : MTT assay demonstrates that Angelica gigas, Rhus verniciflua Stokes, and Trichosanthes kirilowii suppressed strongly the growth of SNU-80. Western blot analysis demonstrates that Trichosanthes kirilowii induces apoptosis activating the cleavages of caspases (caspase-8, caspase-3) and PARP. Wound healing assay demonstrates that Rhus verniciflua Stokes, and Trichosanthes kirilowii inhibited the migration of SNU-80. Transwell invasion assay demonstrates that Rhus verniciflua Stokes, and Trichosanthes kirilowii inhibited the invasion of SNU-80. Elisa assay demonstrates that Astragalus membranaceus, Angelica gigas, Rhus verniciflua Stokes, and Trichosanthes kirilowii suppressed the expression of VEGF and MMP-2. Conclusion : We could conclude that several herbal medicines suppresses the growth and inhibits the migration and invasion of SNU-80 which is anaplastic thyroid cancer cells. Especially, Rhus verniciflua Stokes, Trichosanthes kirilowii had stronger anti-cancer effect suggesting that we can apply them to treat anaplastic thyroid cancer.

Objectives: This study summarizes the current trends and results in clinical studies on herbal medicine treatments after thyroidectomy. Methods: Studies published between 2019 and 2024 were searched for on the China National Knowledge Infrastructure (CNKI), PubMed, and Research Information Sharing Service (RISS). The studies were analyzed according to year, study design, characteristics of the patients, and traditional Chinese medicine (TCM) intervention. A meta-analysis was conducted and classified according to the outcome measurements, such as the total effective rate (TER), thyroid stimulating hormone (TSH), free T4 (FT4), self-rating depression scale (SDS), CD3+, CD4+, and CD8+. CD8+. Results: A total of 18 randomized controlled trials (RCTs) and 5 non-randomized controlled trials were reviewed. The most common herbal prescriptions were decoctions made from Yangyin Sanjie (Yangeumsangyeol-tang), Yiqi Sanjie (Ikgisangyeol-tang), Yiqi Yangyin Sanjie (Ikgiyangeumsangyeol-tang), Yiqi Yangyin (Ikgiyangeum-tang), and Huiyan Zhuyu (Hoeyeomchugeo-tang). The most frequently used herbs were Prunellae Spica, Scrophulariae Radix, and Astragali Radix. The meta-analysis found that the group using both herbal and Western medicine was benefited more than the group using Western medicine alone (RR: 1.28, 95% CI: 1.20-1.37, P<0.00001). The experimental group had higher TSH, CD3+, and CD4+ levels, while FT4, SDS, and CD8++ were lower. However, due to high study heterogeneity, the results were not statistically significant. Conclusion: Complications after thyroidectomy include hypothyroidism, hypoparathyroidism, and psychological aftereffects. Herbal and conventional treatments showed potential in improving hormone levels, immune function, and depression, but statistical significance was limited due to study variability. These results should be interpreted cautiously given the risk of bias in the trials.

Thyroid function is mainly regulated through cAMP and phophatidylinositol, and it is well known that TSH-stimulated thyroxine ($T_4$) release is inhibited by catecholamine from mouse thyroids via the ${\alpha}_1$-adrenoceptor stimulation. Previous study has established that the inhibition of $T_4$ release by ${\alpha}_1$-adrenoceptor stimulation results in activated protein kinase C (PKC). The purpose of this study was to determine if ion transport systems are involved in the inhibition of $T_4$ release elicited by ${\alpha}_1$-adrenergic agonist in mouse thyroids. TSH-, IBMX- and cAMP analogue-stimulated $T_4$ release were significantly inhibited by methoxamine, R59022 (diacylglycerol kinase inhibitor), and MDL (adenylate cyclase inhibitor). TSH-stimulated $T_4$ release could be inhibited by Bay K 8644 and cyclopiazoic acid, but not by verapamil and tetrodotoxin. The addition of nifedipine ($Ca^{2+}$ channel blocker), tetrodotoxin and lidocaine ($Na^+$ channel blockers), but not amiloride (EIPA) and ryanodine, completely blocked the inhibitory effects of methoxamine on $T_4$ release. TSH-stimulated $T_4$ release was also inhibited by benzamil ($Na^+-Ca^{2+}$ exchange inhibitor). TSH-, IBMX- and cAMP-stimulated $T_4$ release were inhibited by methoxamine or R59022, these effects were reversed by nifedipine. but not by verapamil. Furthermore, nifedipine reversed the inhibitory effects of benzamil and R59022 on TSH-stimulated $T_4$ release. These data suggest that the observed ${\alpha}_1$-adrenoceptor-mediated inhibition of $T_4$ release in mouse thyroids is the result of an increase in intracellular $Na^+$ or $Ca^{2+}$ effected via activation of fast $Na^+$ or nifedipine-sensitive $Ca^{2+}$ channels, and that $Na^+-Ca^{2+}$ exchange may play an important role in reducing thyroid hormone by increasing intracellular $Ca^{2+}$.

Objectives: With the recent advances and increasing use of imaging techniques in examination of the neck, the incidence of incidentally discovered thyroid carcinoma has been increasing. This study was carried out to evaluate the clinicopathologic characteristics of incidental thyroid carcinomas and to find optimal therapeutic strategies for these lesions. Materials & Methods: From Jan. 1988 to Aug. 1998, 1,053 patients were operated on for thyroid cancer, of whom 127(12.1%) had incidentally discovered thyroid cancers which were identified during routine health checkups(n=40), diagnostic procedures for unrelated medical conditions(n=39) and mass screening for thyroid cancer(n=48). The preoperative diagnosis was obtained by ultrasound-guided FNAB and the extent of surgery was determined based on frozen section examinations, as well as prognostic factors and gross findings at the time of surgery. Results: There were 6 men and 121 women with a mean age of 45.9 years. Histopathological diagnosis included papillary carcinomas(n=1l9), follicular carcinomas(n=6), poorly differentiated carcinoma(n=l) and medullary carcinoma(n=1). Thirty patients(23.6%) had multifocallesions. The mean diameter of the tumors was 1.1 cm(0.2-3.4 cm). Capsular invasions were found in 53 patients(41.7%) and nodal metastases in 41(32.3%). The surgical procedures used were: 90 less-than total thyroidectomies and 37 total thyroidectomies with central neck node dissection. Lateral neck dissection was added in 5 patients. According to TNM staging, 79 patients(63.2%) were at stage I, 15(12.0%) at stage II, 31(24.8%) at stage III and 0(0.0%) at stage IV. By AMES scoring system, 102 patients(81.6%) were in the low-risk group and 23(18.4%) in the high-risk group. And by MACIS scoring system, 103(86.6%) of 119 papillary thyroid cancer patients were less than 6. Conclusions: The clinicopathological characteristics of incidentally discovered thyroid carcinomas are similar to ordinary thyroid carcinomas. The treatment of choice should be individualized based on the particular clinical situation encountered, as in ordinary thyroid carcinomas.
