Background: A few cases of moyamoya syndrome associated with thyrotoxicosis have been reported. However, studies on the association of hyperthyroidism with moyamoya syndrome are insufficient. Case Report: Here we report a case of hyperthyroidism associated with moyamoya syndrome in a 41-year-old woman with aphasia and right side weakness. Brain imaging revealed acute cerebral infarction of left middle cerebral artery territory and occlusion of bilateral distal internal carotid arteries. Conclusion: Antithyroid medication stabilized the patient's neurologic deterioration, suggesting that thyrotoxicosis could aggravate acute cerebral infarction caused by moyamoya syndrome.

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.

Graves disease (GD) is the most common cause of hyperthyroidism, accounting for more than 90% of cases in Korea. Patients with GD are treated with any of the following: antithyroid drugs (ATDs), radioactive iodine (RAI) therapy, or thyroidectomy. Most patients begin treatment with ATDs, and clinical guidelines suggest that the appropriate treatment period is 12 to 18 months. While RAI treatment and surgery manage thyrotoxicosis by destroying or removing thyroid tissue, ATDs control thyrotoxicosis by inhibiting thyroid hormone synthesis and preserving the thyroid gland. Although ATDs efficiently control thyrotoxicosis symptoms, they do not correct the main etiology of GD; therefore, frequent relapses can follow. Recently, a large amount of data has been collected on long-term ATDs for GD, and low-dose methimazole (MMZ) is expected to be a good option for remission. For the long-term management of recurrent GD, it is important to induce remission by evaluating the patient's drug response, stopping ATDs at an appropriate time, and actively switching to surgery or RAI therapy, if indicated. Continuing drug treatment for an extended time is now encouraged in patients with a high possibility of remission with low-dose MMZ. It is also important to pay attention to the quality of life of the patients. This review aimed to summarize the appropriate treatment methods and timing of treatment transition in patients who relapsed several times while receiving treatment for GD.

The present study was carried out to investigate the effects of nitrate ($KNO_3$) on the thyroid glands in rabbits which were administrated $KNO_3$ of 1g/kg/day for 6 weeks. Growth rate, and serum levels for $T_4$, $T_3$ and TSH were observed every weeks. The histological changes and the weights of the thyroid glands were observed in 6 weeks. The results obtained were summarized as follows: 1. The mean growth rates of experiments were decreased significantly in the 1st week, but were increased a little from the 5th to 6th week compared with those of controls. 2. The serum levels for $T_4$ of the experimental group manifested significantly decreased values than those of control through the experimental term consistently and the serum levels for $T_3$ were greatly decreased in the 3rd and 4th weeks. 3. TSH contents of the serum were not changed through the experimental term. 4. The mean weight of the thyroid gland in the experiment was decreased significantly after 6 weeks compared with that of control. 5. In the experimental group, the color of colloid in the thyroid follicles revealed deeper eosinophilic and the heights of the follicular epithelial cells were taller than those of controls. The colloid in the thyroid follicles revealed depletion. As summarized above, the observations suggest that nitrate can be an antithyroid substance in rabbits and it leads the thyroid glands to hypofunctional state.

The serum concentrations of thyrotropin (TSH) were measured by means of radioimmunoassay, in 98 cases of normal controls, 51 cases of hyperthyroidism, 80 cases of primary hypothyroidism and 4 cases of secondary hypothyroidism to evaluate the diagnostic significance in various functional states of the thyroid. The obtained data were analyzed in correlation with other thyroid function test values in various phases of the functional thyroid diseases. The results were as follows: 1) The serum TSH concentration in normal control group was $<1.3{\sim}8.0{\mu}U/ml$. 2) The measurement of serum TSH was more significant in diagnostic accuracy compared with that of serum $T_4(75.0{\pm}12.2%)$. Free $T_4$ Index ($64.2{\pm}15.2%$), serum $T_3(41.0{\pm}21.0%)\;or\;T_3$ resin uptake ($41.1{\pm}15.8%$) in evaluation of primary hypothyroidism. 3) In case of overt hypothyroidism, the serum TSH and $T_4$ were both abnormal, compatible with the clinical diagnosis, while in case of preclinical or mild hypothyroidism, the serum $T_4(41.2{\pm}23.8%)\;or\;50.0{\pm}25.0%)$ was much less reliable than serum TSH. 4) In the treatment of primary hypothyroidism with desiccated thyroid, the administration of 1 grain of the hormone per day was sufficient to suppress the serum concentration of TSH to normal range. It showed that the measurement of serum TSH concentration was a significant criteria in evaluating the efficiency of the treatment of hypothyroidism. 5) The measurement of serum TSH concentration is a very significant method in the early detection of hypothyroidism induced during or after the treatment of the hyperthyroidism with antithyroid drugs or radioactive Iodine ($^{131}I$).

Appreciable radiation exposures certainly occur in the workers who handle radioiodine in biochemical research, nuclear medicine diagnostics with the development of nuclear industries. But in the case of occurring the nuclear accidents, the early medical treatment of radiation injury should be necessary but little was reported in korea till now. Accordingly, to achieve of the basic data for protective roles and medical treatment of radiation injury, the present studies were carried out to evaluate the decontamination of radioiodine by the administration of the antithyroid drugs. The results observed are summarized as follows: 1. The administration of sodium iodide and potassium iodide results in rapid excretion of radioiodine and reduction of the whole body retention than the saline-only group. 2. Reguarding to thyroid protective effects, sodium iodide, potassium iodide and saline were effected significant in order. 3. In the control(saline) group, if administered with enough fluids, the whole body retention of radioiodine is reduced temporary shifts. But as far as radioprotective effects is concerned, saline was not more in the protective effects than the other groups. In conclusion, in case of nuclear accidents, if being administered sodium iodide and saline as quickly as possible, the radioprotective effects against the radiation hazard might be markedly increased in the internal contamination of radioiodine.

742 cases of thyroid diseases treated at Radio-isotope Clinic, Seoul National University Hospital since October 1965 through July 1968 were analyzed. The patients were classified according to eye findings, as to Infiltrative, Non-infiltrative and No ophthalmopathy. Correlations between ophthalmological findings and symptoms, BMR values and $^{131}I$ uptake rate as well as response to medical treatment were carefully reviewed. Results obtained were as follows: 1. Among goitrous patients 44.5% with infiltrative ophthalmopathy, 24.1% with non-infiltrative ophthalmopathy totaling 68.6% of patients with one or more eye findings were found. Exophthalmos (44%) and visual disturbances (44%) comprised the highest incidence among eye signs. Most frequent eye symptoms were lid swelling (17.1%). 2. Female patients were predominant(91%). 3. Of cases with hyperthyroidism, after treatment with antithyroid drugs and radio-iodine therapy, general symptoms were improved in over 74%, whereas ophthalmopathy was not changed and in some cases the eye signs were aggravated. This tendency was more apparent in infiltrative ophthalmopathy. 4. Significant correlations between exophthalmos, BMR values and $^{131}I$ uptake rate were found. Among the patients of same degree of exophthalmos, BMR values and $^{131}I$ uptake rate showed the highest in non-infiltrative ophthalmopathy, moderate in infiltrative ophthalmopathy and the lowest in no ophthalmopathy.

Objective: This study was performed to research Korean medical treatment methods for hyperthyroidism by summarizing domestic clinical studies. Methods: The study was based on 14 papers published in Korea since 2000, on Korean medicine treatments for hyperthyroidism. Papers were searched on four domestic electronic databases. Results: 1. This paper analyzed 14 studies on the subject of clinical research on hyperthyroidism in Korea. 12 of them reported cases while two of them reported on clinical research. 2. The average age of the subjects was 39 years, 71.3% of women, 20-60 years of age accounted for 92%, and the average duration of disease was 22 months. 3. Of the 115 subjects, 102 had experienced Western medical treatment. So most of them chose Western medical treatment as the first treatment method, of which 24 experienced side effects. 4. Eumhuhwadong (陰虛火動) and Gieumyanghu (氣陰兩虛) appeared 3 times respectively. 5. The Korean herbal medicine, Ahnjeonbaekho-tang was the most frequent herbal medicine used to treat hyperthyroidism, with the next most frequent being Yanggyuksanhwa-tang. 6. The study, which was performed using herbal medicine alone, showed a marked improvement in clinical symptoms and thyroid function test, compared with administration of antithyroid drugs and herbal medicines. Conclusions: Large-scale studies and randomized controlled trials will be needed to evaluate the validity of Korean medical treatment for hyperthyroidism.
