Objective : Although hypothyroidism is a common disease in the endocrinology system, it is reported that there are a lot of difficulties in treating it effectively. Aconiti Ra얕 traditionally has been used in treatment of coldness, fatigue, and bradycardia. In this study, we investigated the therapeutic effects of Aconiti Radix on hypothyroidism rat model induced by 6-propyl-2-thiouracil (PTU). Methods : Two-month-old rats were used with administration of PTU which induced hypothyroidism in the rats. After 2 weeks, Aconiti Radix and thyroxine were administered, respectively. The body weights were measured every week. After 4 weeks, the blood samples of all rats were taken from their hearts. They were analyzed biochemically and $T_4$ (thyroid hormone) & TSH (thyroid stimulating hormone) was measured by ELISA kits. Results : In comparison with normals, controls showed hypothyroidism with significantly low $T_4$ and high TSH the statistics. In Aconiti Radix administration groups significantly increased $T_4$ was observed in the statistics and its effects were dose-dependent. There was no difference statistically in TSH of Aconiti Radix treatment groups from controls, nor were statistical differences observed significantly in biochemical labs and weight of each group. Conclusions : These findings suggest that Aconiti Radix protects thyroid cells and makes thyroid cells produce thyroid hormones. It is also very safe in the view of liver, kidney function, and other metabolism. It may be a useful agent for treating hypothyroidism.

Hypothyroidism is a common disease of the endocrinal system, characterized by fatigue, cold intolerance, bradycardia, and so on. Subclinical hypothyroidism is a common biochemical abnormality which can be found in routine screening tests of thyroid function. It is defined as an asymptomatic state which characterized by normal free thyroxine(FT4) and elevated thyroid stimulating hormone(TSH) levels. The purpose of this study was to evaluate the effect of treatment with palmijihwang-tang and to observe the changes in triiodothyronine(T3), free thyroxine(FT4), thyroid stimulating hormone(TSH) level and VAS of cold intolerance, hoarseness, dry skin. After the treatment, triiodothyronine(T3) increased from 57.12ng/dl to 120.53ng/dl. Free thyroxine(FT4) increased from 12.59pg/ml to 14.21pg/ml. Thyroid stimulating hormone(TSH) decreased from 10.61mU/L to 1.57mU/L. Cold intolerance, hoarseness and dry skin changed for the better. These results support a role for oriental medical therapy in treating subclinical hypothyroidism. Further case studies of herbal treatment of this ailment are needed.

Subclinical hypothyroidism can be defined as an asymptomatic state in which a reduction in thyroid activity has been compensated by an increased TSH output to maintain a euthyroid state. We analysed clinical features, laboratory data, and pathologic findings in 3g cases of subclinical hypothyroidism who were diagnosed at the Dept. of Internal Medicine, Chungnam National University Hospital from Aug. 1984 to June, 1985. 1) The age distribution was from sixteen to sixty-nine and mean a9e was 34.8. Peak incidence was in the 4th decade and 3rd, 5th, 6th decade in order. 2) The sex distribution showed female preponderance with a ratio of 18.5 to 1. 3) The major presenting manifestations were nonspecific ones such as fatigue, indigestion, and anorexia. 4) Physical examination revealed diffuse goiter in 47.6%. Major abnormalities were no gross abnormality (30.9%), nodular goiter and facial edema. 5) There was no significant difference of the basal serum $T_3\;and\;T_4$ concentrations between subclinical hypothyroidism and normal controls (p>0.05). 6) The basal serum TSH concentration of subclinical hypothyroidism $(32.61{\pm}14.95{\mu}U/ml)$ was significantly higher than that of normal controls $(3.92{\pm}1.05{\mu}U/ml)$ (p<0.005). 7) Microsomal antibody was detected in 80.6% and thyroglobulin antibody was detected in 30%. 8) The pathologic findings in 26 cases revealed Hashimoto's thyroiditis in 76.9% (lymphocytic type, 34.6%; oxyphilic type, 26.9%; fibrotic type, 15.4%). The others were adenomatous goiter(15.4%), adenomatous carcinoma (3.8%) and subacute thyroiditis(3.8%).

Objective : Hypothyroidism is a common disease of the endocrinal system. characterized by fatigue, cold intolerance, bradycardia, and so on. Clinically, Levothyroxine(L-T4) has been usually used for replacement therapy, but it often has side effects. so many hypothyroidism patients wants oriental medical therapy. Zingiberis rhizoma, traditionally has been used in treatment of coldness, fatigue, and bradycardia. In this study. I investigated the therapeutic effects of Zingiberis rhizoma on PTU induced hypothyroidism in rats. Methods : I used two-month-old rats administered PTU and induced with hypothyroidism. After 2 weeks. Zingiberis rhizoma and thyroxine were daily administered, respectively. Body weights was measured every weeks. After 4 weeks, blood samples were taken and analyzed biochemically and T4 and TSH were measured by ELISA kits. Results : In comparison with normal groups, control groups showed hypothyroidism with low T4 and high TSH level. In Zingibris rhizoma administration groups were observed T4 level elevation, this elevation was dependent on the dose of Zingibris rhizoma. Between experimental groups and control groups, there was no difference in TSH level, statistically. Changes of biochemistry were not observed in any experimental groups. Conclusions : These findings suggest that Zingiberis rhizoma makes thyroid cells producing thyroid hormones. There is also a non-toxic effect on the cardiovascular system, liver and kidney function. So, Zingiberis rhizoma should be an effective agents for treating hypothyroidism.

Objective : To suggest a scientific evidence of Aconitum carmichaeli Debx. (Aconiti Lateralis Radix Preparata: ALRP) as one of cooling and heating medicines on the regulation of body temperature, we investigated the effects of ALRP water extract on hypothyroidism. Methods : Hypothyroidism was induced by intradermal injection with PTU for 4 weeks in SD rats. ALRP extract or L-thyroxine as a control drug was orally administrated for 2 weeks with PTU injection in rats. The physiological and serological parameters were measured in rats. The histological change of thyroid tissues was observed by H&E staining, and also the expression of thermo-regulating proteins was determined by Western blot in dorsal root ganglia and brain tissues of rats. Results : The administration of ALRP extract in PTU-induced hypothyroidism rats was significantly increased body temperature, but did not changes on body weight, food and water intake. ALRP extract did not effect on the levels of TSH and T4 in the hypothyroidism rats. ALRP extract significantly decreased the levels of GPT, glucose, HDL-cholesterol, LDL-cholesterol, and total cholesterol in the hypothyroidism rats. In histological observation, the enlarged epithelium and atrophic follicles with higher concentration of follicular cells on hypothyroidism were improved by ALRP extract. In addition, ALRP extract increased the expression of TRPV1 and TRPM8 ion channel proteins in hypothyroidism rats. Conclusion : These results indicate that ALRP extract can improve PTU-induced hypothyroidism through regulation of body temperature and lipid accumulation. The action mechanism of ALRP extract is related with body temperature control by thermoregulation with TRP ion channels.

Pseudohypoparathyroidism (PHP) is a rare disorder caused by genetic and epigenetic aberrations in the GNAS complex locus resulting in impaired expression of stimulatory G protein ($Gs{\alpha}$). PHP type Ib (PHP-Ib) is characterized by hypocalcemia and hyperphosphatemia due to renal resistance to the parathyroid hormone, and is distinguished from PHP-Ia by the absence of osteodystrophic features. An 11-yr-old boy presented with poor oral intake and cramping lower limb pain after physical activity. Laboratory studies revealed hypocalcemia, hyperphosphatemia, and increased parathyroid hormone levels. The GNAS complex locus was evaluated using the methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) assay. Gain of methylation in the NESP55 domain and loss of methylation in the antisense (AS) transcript, XL, and A/B domains in the maternal allele were observed. Consequently, we present a case of PHP-Ib diagnosed using MS-MLPA.
