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.

Thyroid hormone-induced cellular dysfunctions may be associated with changes in the intracellular $Ca^{2+}$ concentration. The ryanodine receptor, a $Ca^{2+}$ release channel of the SR, is responsible for the rapid release of $Ca^{2+}$ that activates cardiac muscle contraction. In the excitation-contaction coupling cascade, activation of ryanodine receptors is initiated by the activity of sarcolemmal $Ca^{2+}$ channels, the dihydropyridine receptors. In hyperthyroidism left ventricular contractility and relaxation velocity were increased, whereas these parameters were decreased in hypothyroidism. The mechanisms for these changes have been suggested to include alterations in the expression and/or activity levels of various proteins. In the present study, quantitative changes of ryanodine receptors and the dihydropyridine receptors, and the functional consequences of these changes in various thyroid states were investigated. In hyperthyroid hearts, $[^3H]ryanodine$ binding and ryanodine receptor mRNA levels were increased, but protein levels of ryanodine were not changed significantly. However, the above parameters were markedly decreased in hypothyroid hearts. In case of dihydropyridine receptor, there were a significant increase in the mRNA and protein levels, and [3H]nitrendipine binding, whereas no changes were observed in these parameters of hypothyroid hearts. Our findings indicate that hyperthyroidism is associated with increases in ryanodine receptor and dihydropyridine receptor expression levels, which is well correlated with the ryanodine and dihydropyridine binding. Whereas opposite changes occur in ryanodine receptor of the hypothyroid hearts.

This study was conducted to investigate the effect of dietary thyroid hormone (T$_3$and T$_4$) on growth, feed conversion ratio and serum T$_3$or T$_4$concentration of broiler chicks. Zero to six week-old broiler chicks were randomly allocated into seven treatment groups for feeding trials with three replication : control, T$_3$(0.1), T$_3$(1.0), T$_3$(5.0), T$_4$(0.1), T$_4$(1.0), T$_4$(5.0) ppm group. Concentrations of T$_3$and T$_4$in serum were analyzed. The weight gain of T$_3$(1.0), T$_3$(5.0) and T$_4$(5.0) groups were significantly lower than that of control. No statistically significant adverse effect was observed in other groups (p〉0.05). Feed intake was significantly lower in T$_3$(0.1, 1.0 and 5.0) and T$_4$(5.0) than in control group (p〈0.05), and the feed conversion ratio had a similar trend to the feed intake change. The contents of liquid and abdominal fat pad in carcass were significantly decreased in all T$_3$and T$_4$groups (p〈0.05). T$_3$and T$_4$concentration in serum was significantly increased at over 1.0ppm of the hormone supplementation level. As T$_3$addition level increased, T$_4$concentration in serum reduced ; however, T$_3$in serum was directly proportional during fasted were slightly increased when T$_3$or T$_4$was added to broiler diets.

Background and Objectives:This study is to objectively compare and analyze the acoustic changes in the patients with total thyroidectomy before and after RI therapy. Subjects and Methods:For this study, a total of 50 patients with total thyroidectomy were participated as subjects. Voice samples were obtained at the time of post-operation (Post-OP), before high-dose radioactive iodine therapy (Pre-RIT), and after high-dose radioactive iodine therapy (Post-RIT). Acoustic analysis, the maximum phonation time and K-VHI (Korea-Voice handicap index) were used for subjective evaluation. Results:According to the comparison analysis of the three periods, mFo (Hz) was significantly reduced in all of the vowels /a/ and /i/ as the hormone was discontinued. This can be related to the reduction in vocal range. As thyroid hormone was discontinued, Shim (%) and APQ (%) values, which are the parameters related to the degree of aggressiveness, showed a significant increase in the middle vowel /a/. As thyroid hormone was discontinued, emotional index was significantly decreased in VHI (voice handicap index). Conclusion:These results can be assumed that thyroid hormone suspension is related to the increased changes in the vocal intensity, the increase in noise and the reduction in vocal range. Emotionally, these data can be assumed that the responsive factors of one's own voice disorders were significantly decreased in the patients with vocal handicap.

목 적 : 갑상선 기능은 여러 질환이나 스트레스에 의해서 영향을 받는 것으로 알려져 있다. 저자들은 분만 전과 분만 동안의 여러 인자와 제대혈 갑상선자극호르몬 및 갑상선호르몬 농도와의 상관관계를 알아보고자 본 연구를 시행하였다. 방 법 : 총 130명의 신생아를 대상으로 분만 즉시 제대혈을 10 mL 채취하여 갑상선자극호르몬, $T_3$와 유리 $T_4$ 농도를 방사면역학적 방법(CIS bio international kit, Germany)으로 측정하였다. 재태연령, 출생체중, 가사, 분만방식, 산모의 당뇨병 유무, 산모의 전자간증 유무 등에 따라 갑상선자극호르몬과 갑상선 호르몬 농도를 비교하였다. 결 과 : 1) 제대혈 갑상선자극호르몬 농도는 재태연령 34주 이하 $1.73{\pm}0.48{\mu}IU/mL$, 34주-37주 $2.60{\pm}0.51{\mu}IU/mL$, 38주 이상 $4.26{\pm}0.40{\mu}IU/mL$으로 재태연령의 증가에 따라 증가하였다(P<0.05). 2) 분만형태를 비교하면 질식 분만 군 $4.42{\pm}0.66{\mu}IU/mL$, 제왕절개 분만 군 $3.31{\pm}0.33{\mu}IU/mL$로 질식 분만 군에서 높았다(P<0.05). 3) 가사에 따른 갑상선자극호르몬 농도는 가사가 있는 군 $5.18{\pm}0.93{\mu}IU/mL$로 가사가 없는 군 $2.97{\pm}0.84{\mu}IU/mL$에 비해 유의하게 높았다(P<0.05). 4) 산모의 당뇨병에 따른 갑상선자극호르몬 농도는 당뇨병 군 $8.91{\pm}1.25{\mu}IU/mL$, 없는 군 $4.32{\pm}0.42{\mu}IU/mL$으로 산모 당뇨병 동반시 유의하게 높았다(P<0.05). 5) 산모에게 전자간증이 있는 군의 갑상선자극호르몬 농도는 $5.28{\pm}0.42{\mu}IU/mL$, 없는 군 $3.65{\pm}0.46{\mu}IU/mL$에 비해 유의하게 높았다(P<0.05). 6) $T_3$와 유리 $T_4$ 농도는 가사 군에서 없는 군보다 유의하게 낮았다(P<0.05). 7) 각 변수 간의 영향을 배제하였을때 임신주수, 1분 Apgar 점수, 산모의 당뇨병만이 독립적으로 제대혈의 갑상선자극호르몬 농도에 영향을 미치는 것으로 나타났다. 결 론 : 제대혈 갑상선자극호르몬 및 갑상선호르몬 농도는 산모의 당뇨병이나 산모 전자간증과 같은 분만 전 요인과 태아에게 저산소증을 초래할 수 있는 분만시 스트레스와 밀접한 연관이 있다.
