For the assessment of antithyroid effect of lithium carbonate, it was administered to the 17 hyperthyroid and 5 euthyroid patients, who visited the Seoul National University Hospital from Jan. to Aug., 1977. Thyroid function tests were performed just before the administration of Lithium carbonate, 2 weeks and 2 months after lithium treatment. The results were as follows; 1) In the 5 euthyroid patients, no significant changes in thyroid function tests were obtained before and after lithium treatment. 2) In the 17 hyperthyroid patients, the values of the $T_3RIA$ were $370{\pm}121ng/dl$ 2 weeks after lithium treatment as compared with $506{\pm}121ng/dl$ before the administration, of which the mean percentage fall was 26.9%. $T_3RU$ was varied from $56.8{\pm}8.0%\;to\;47.3{\pm}8.1%$ (16.7% in mean percentage fall), $T_4$ was changed from $24.2{\pm}2.4ug/dl\;to\;22.0{\pm}4.2ug/dl$ (9.1% in mean fall), and $T_7$, from $13.82{\pm}2.25\;to\;10.55{\pm}3.12$ (23.7% in mean fall). 3) In the 5 hyperthyroid patients, serial thyroid function tests were performed 2 weeks and 2 months later. The mean percentage falls of $T_3RIA$ were 36.6 and 61.3%, 2 weeks and 2 months after lithium treatment respectively. Those of $T_3RU$ were 17.5 and 35.1%, those of $T_4$ were 20.4 and 44.0%, $T_7$, 35.0 and 60.7%. 4) Approximately $45{\sim}60%$ of mean fall in thyroid function tests were obtained within the second week. Normal thyroid function tests were observed in 2 among 17 patients within the second week, and 2 among 5 patients within the second month. 18 patients, however, became clinically euthyroid within the 4th week. 5) Single case of hypothyroidism was experienced, and 5 patients (29.4%) complained mild side effects. Lithium salts could be safely administered to hyperthyroid patients who are allergic to thioamides or iodine. Its use is indicated in cases of acute thyrotoxicosis in which it's necessary to reduce hormone levels very rapidly, and lithium-thioamides drug combination is a highly effective and safe means of initial routine control of hyperthyroidism.

Autoimmune thyroiditis is the most common cause of hypothyroidism in the world. It is characterized clinically by gradual thyroid failure, goiter formation, or both, because of the autoimmune-mediated destruction of the thyroid gland. Renal involvement presenting proteinuria in autoimmune thyroiditis is not uncommon, occurring in 10% to 30% of the cases. Glomerulonephropathy associated with autoimmune thyroiditis, however, is a rare disease. Most reports of autoimmune thyroiditis with glomerulonephropathy have demonstrated a mixed pathological morphology and have been predominantly associated with membranous glomerulopathy. The case of minimal-change disease associated with thyroiditis presenting acute kidney injury is a rare disease that has not been reported in South Korea. Reported herein is the case of a 16-year-old man diagnosed with Hashimoto's thyroiditis, with minimal-change disease presenting acute kidney injury. He revealed hypothyroidism, proteinuria, and impaired renal function. Renal biopsy showed minimal-change disease and minimal tubular atrophy. The patient was treated with thyroid hormone, and his renal function and proteinuria improved. Therefore, for patients with autoimmune thyroiditis presenting unexplained proteinuria, glomer-ulonephropathy should be ruled out. Conversely, for patients with glomerulonephropathy and persistent proteinuria despite proper treatment, thyroid function and antibody tests should be performed.

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 ($^{131}I$).

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.

Purpose: The purpose of this study was to evaluate short-term thyroid dysfunction and related risk factors in pediatric patients who underwent hematopoietic stem cell transplantation (HSCT) during childhood. Methods: We studied 166 patients (100 boys and 66 girls) who underwent HSCT at the Catholic HSCT Center from January 2004 through December 2009. The mean age at HSCT was $10.0{\pm}4.8$ years. Thyroid function of the patients was tested before and during 3 months of HSCT. Results: Out of 166 patients, 165 (99.4%) underwent allotransplantation. Acute graft-versus-host disease (GVHD, grades II to IV) developed in 76 patients. Conditioning regimens before HSCT include total body irradiation (n=57), busulfan (n=80), and reduced intensity (n=29). Forty-five (27.1%) had thyroid dysfunction during 3 months after HSCT (29 euthyroid sick syndrome [ESS], 6 subclinical hyperthyroidism, 4 subclinical hypothyroidism, 3 hypothyroxinemia, 2 overt hyperthyroidism, and 1 high $T_4$ syndrome). In a univariate logistic regression analysis, age at HSCT (P=0.002) and acute GVHD (P=0.009) had statistically significant relationships with thyroid dysfunction during 3 months after HSCT. Also, in a univariate logistic regression analysis, ESS (P=0.014) showed a strong statistically significant association with mortality. Conclusion: In our study 27.1% patients experienced thyroid dysfunction during 3 months after HSCT. Increase in age and acute GVHD may be risk factors for thyroid dysfunction during 3 months after HSCT. There was a significant association between ESS and mortality.

In recent years with development of immuno-electrophoresis, more acurate analysis of the serum protein became possible. However, there is few reports in the literature which investigated the changes of the immunoglobulin compared with electrophoretically fractioned serum thyroglobulin in the patients with various thyroid diseases. The purpose of this report is to investigate the changes of thyroglobulin in various thyroid diseases by the method of immuno-electrophoresis and to compare the results with.serum protein fractionated by the method of agar-gel micro-electrophoresis. Materials and Methods: Sera from 9 patients with diffuse toxic goiter, 2 nodular nontoxic goiter, 2 thyroiditis, 3 hypothy, roidism, 1 thyroid cancer, 7 cystic degeneration of the thyroid gland, and 10 normal subject were taken. All cases were confirmed by various laboratory thyroid function tests and thyroid needle biopsy. Immuno-electrophoretic analysis of the serum were performed by Scheidegger's modified micro-immuno-electrophoretic method. The antiserum was obtained from the Travenol Laboratories International, Hyland Products Division and was rabbit anti-human thyroglobulin. Microscope slide agar-gel electrophoresis for serum protein fractionation was performed at $4^{\circ}C$ using veronal buffer, pH 8.6 and ionic strength 0.05, with 54 volts and 2.8 mA for 60 minutes. The fractionated slide was stained with 0.1% thiazine red. The results were as follows: 1) Increase of immune-globulin macroglobulin (IgM), alphaglobulin, and immune-globulin A (IgA) by 95.8%, 100%, 29.2% respectively was found in the serum from various thyroid diseases. 2) Thyroglobulin fraction was found to be increased in 50%, no change in 41.7%, and no line in 8.3% with all of the various goiter patients. On the other hand, 10 normal control group showed only 2 cases of increase, 5 cases of no change and 3 cases of no line.

Purpose : In this study, we analyzed the short term changes of thyroid function, incidence and risk factors of thyroid dysfunction soon after allogeneic hematopoietic stem cell transplantation (HSCT) in children. Methods : We enrolled 80 pediatric patients following allogeneic HSCT, at the Catholic HSCT center between January, 2004 and February, 2006. Serum TSH (thyroid stimulating hormone), total serum thyroxine and total serum triiodothyronine levels were systematically measured in 80 patients before the HSCT, and at 1 month, 6 months and 12 months after HSCT. Results : Thyroid function statistically decreased at 1 month after HSCT(P<0.001). Thyroid dysfunction at 1 month was observed in 43 (54 percent) of 80 patients, 31 (39 percent) of whom presented with euthyroid sick syndrome (ETS). Thyroid dysfunction was normalized within 1 year after HSCT. In univariate analysis, malignant disease and the presence of acute graft-versus-host disease (grade ${\geq}II$) were risk factors for ETS (P=0.04, 0.01 respectively). In multivariate analysis, we could not detect an independent risk factor for ETS (P=0.19, 0.06 respectively). Conclusion : The present study suggests that the incidence of thyroid dysfunction is high after allogeneic HSCT. Therefore, regular monitoring of thyroid hormone levels after HSCT is required.

Background and Objective: Percutaneous ethanol injection therapy has been used in the treatment of the benign thyroid diseases. Although the reported side-effects of the therapy was mild and transient, some side-effects including local or radiating pain are troublesome to the patients. Radioactive iodine-131($Ra-^{131}I$) also has been effectively and safely used for management of the benign thyroid diseases. So we developed the percutaneous intranodular injection therapy of $Ra-^{131}I$ as an alternative of percutaneous ethanol injection therapy. Materials and Methods: From December 1998 to October 1999, we treated 29 outpatients (25 women and 4 men, mean age: $47{\pm}12$ years). Inclusion criteria were follows; age >30 years, cytologically benign, with normal thyroid function, cold nodule on thyroid scintigram, solid or mixed natured nodules in sonographical evaluation. Nodular volume was estimated by sonography according to the ellipsoid formula. $Ra-^{131}I$(0.1mCi/ml) was administered in a single dose injection. Follow-up studies every 3 months consisted of full history, thyroid function test, and sonography. We determined the therapeutic response is effective if the volume reduction of the nodule occurred above 30%. Results: After at least 3 months follow-up, 11 patients showed effective response, 12 patients showed minimal or unchanged response and 6 patients showed progression. Although side-effects such as injection pain, febrile reaction, and hormonal changes were absent, an infectious complication in injection site was developed from 1 case. Conclusion: Although we need a more prolonged follow-up to evaluate the delayed sequelae, we can suggest that percutaneous intranodular injection therapy of $Ra-^{131}I$ may be an attractive non-surgical treatment in selected cases of benign thyroid nodules.

Amyloid golfer is a rare disease entity that is defined as a symptomatic mass or clinically detectable thyroid enlargement because of amyloid deposition. We present a case of amyloid golfer diagnosed in the fine needle aspiration cytology(FNAC) in a 73-year-old Korean woman presented with nephrotic syndrome and thyroid enlargement. The thyroid function was in normal range. Thyroid scan showed a nodule, $4{\time}2cm$ in the right lobe with underlying diffuse golfer. Aspirates revealed benign looking follicular cells and scattered eosinophilic material. The sections of the cell block showed nodular deposit of eosinophilic hyalinized material in the interfollicular area. It showed apple-green birefringence under polarization with Congo red stain. The renal biopsy also exhibited deposition of eosinophilic materials in the glomeruli and interstitial vascular wall, which were confirmed as amyloidosis. This material was morphologically distinct from the colloid.

The present study compared leptin, adiponectin, and thyroid hormone concentrations in normal and obese dogs, and evaluated the association between leptin and adiponectin concentrations and thyroid function. The serum leptin, adiponectin, thyroid-stimulating hormone (TSH), total thyroxine (tT4), free thyroxine (fT4), triiodothyronine (T3), and cortisol concentrations were measured in 18 normal dogs (body condition score [BCS]: 4-5/9) and 16 obese dogs (BCS: 8-9/9). Leptin and T3 concentrations were higher in the obese group than the normal weight group (p < 0.01 and p < 0.05, respectively). In both groups, the T3 and leptin concentrations were correlated (r = 0.370, p < 0.05), as were the TSH and fT4 and adiponectin concentrations (r = -0.373, p < 0.05 and r = 0.369, p < 0.05, respectively). In the normal weight group, the TSH and fT4 concentrations were correlated with the adiponectin concentrations (r = -0.528, p < 0.05 and r = 0.482, p < 0.05, respectively). The results of the present study suggest that leptin and T3 concentrations are significantly higher in obese dogs than normal weight dogs, and the serum T3 and leptin concentrations are positively correlated.
