Cystic parathyroid adenoma is one of rare causes of hyperparathyroidism, and tends to cause increased serum level of parathyroid hormone, alkaline phosphate and serum calcium level similar to when compared to those of solid adenoma. The possibility of a coincidental appearance of primary hyperparathyrodism and nonmedullary thyroid cancer is rare, and often neglected. A 40-year-old female presented with constipation and weight loss for 3 months. The serum calcium, phosphate and alkaline phosphate were 16.6 mg/dl, 2.2 mg/dl and 505 IU/L respectively and serum parathyroid hormone level was 1556.2 pg/mL. Neck US showed mixed nodules at both thyroid lobes, and PET-CT showed a right thyroid nodule without FDG uptake. The patient was diagnosed of primary hyperparathyroidism and underwent parathyroidectomy and a total thyroidectomy. Histopathologic results revealed parathyroid adenoma with cystic change (2 cm greater diameter) in the right lower parathyroid gland and coexistent papillary carcinoma of the right lobe of thyroid gland (infiltrating, 0.3 cm in greater diameter). She remained well and serum calcium, phosphate, parathyroid hormone level were normalized within 24 hours.

The effects of the thyroid hormone ($T_3$) on 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase activity were evaluated in a baby hamster kidney cell line, C100. The cells cultured in MEM were supplemented with 10% thyroid hormone-depleted fetal bovine serum (THDS-MEM) and had a 82.5% lower level of HMG-CoA reductase activity than the cells grown in a medium supplemented with fetal bovine serum (FBS-MEM). When $T_3$ was supplemented to THDS-MEM, the reduction of the reductase activity was blocked in a dose-dependent manner. In the cells grown in THDS-MEM containing $T_3$ at a concentration of $10^{-6}$ M, the level of HMG-CoA reductase activity was 91.8% relative to the cells grown in FBS-MEM. These changes in HMG-CoA reductase activity seemed to be at least partly due to the changes of HMG-CoA reductase mRNA levels. The level of HMG-CoA reductase mRNA in cells incubated in THDS-MEM decreased to 76.2% relative to the cells grown in FBS-MEM, while the level of reductase mRNA in cells incubated in THDS-MEM containing $T_3$ at a concentration of $10^{-6}$ M increased to 243.4% relative to the cells grown in FBS-MEM. The increase of HMG-CoA reductase mRNA level after $T_3$ treatment may have been due to the increased stability of reductase mRNA, because the transcriptional rate of the reductase gene did not change significantly in the presence or absence of $T_3$. These results indicate that $T_3$ stabilizes HMG-CoA reductase mRNA at the posttranscriptional level and regulates HMG-CoA reductase activity in a dose-dependent manner.

Background: Shift work is known to cause changes in the circadian rhythm of the human body and adversely affect not only physical health but also mental health. Some studies have demonstrated the correlation between shift work and thyroid stimulating hormone (TSH), a hormone that changes according to the diurnal rhythm, but few studies have reported the different TSH levels according to the shift work type. This study aimed to investigate changes in TSH according to the shift work type. Methods: This study included 1,318 female workers who had a medical checkup at a university hospital in Changwon from 2015 to 2019. Shift work types were classified as non-shift work, regular 2 shifts, and irregular three shifts, and a TSH ≥ 4.2 mIU/L was defined as abnormal. A general linear model (GLM) was used to compare the TSH levels and the risk of subclinical hypothyroidism in each year, and a binary logistic analysis was performed using a generalized estimation equation (GEE) to compare the risk of subclinical hypothyroidism over the 5-year period. Results: Of the 1,318 participants included in this study, 363, 711, and 244 were non-shift, two-shift, and irregular three-shift workers, respectively. In the GEE analysis, after adjusting for age, body mass index, smoking, and alcohol consumption, the odds ratios (ORs) were 1.81 (95% confidence interval [CI]: 1.15-2.86; p = 0.011) in 2 shifts and 2.02 (95% CI: 1.23-3.32; p = 0.006) in irregular three shifts, compared to non-shift. Conclusions: Our results showed that shift work had a higher risk of subclinical hypothyroidism than non-shift work and that there was a significant difference in the risk of subclinical hypothyroidism according to the shift work type. These findings suggest that the shift work type can be considered in future thyroid function tests and evaluations.

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.

1994년 12월부터 1995년 6월까지 연세대학교 원주의과대학 원주기독병원 정신과 병동에 입원한 20명의 양극성 장애 조증 환자들을 대상으로 하여 입원 당시와 입원후 6주에 갑상선 호르몬(T3, T4, TSH)과 조증 증상척도(YMRS)를 조사하여 다음의 결과를 얻었다. 1) 입원후 6주 갑상선 호르몬 측정치는 T3의 경우 입원당시에 비해 평균치가 약간 증가하였으나, 증가 9명, 감소 11명이었다. T4의 경우 평균치는 비교적 크게 감소하였으며 증가 4명, 감소 16명이었다. TSH평균치는 증가하였으며, 증가 14명, 감소 6명이었다. 2) 입원후 6주의 YMRS 총점 평균은 입원당시에 비해 현저히 감소하였고 YMRS의 11개 하위척도의 평균 점수도 감소하였다. 3) 입원 당시와 입원후 6주의 T3, T4, TSH의 변화와 YMRS의 변화 사이의 관계를 조사한 바, T3의 경우, 증가, 감소, 변화없음의 3군간에 YMRS하위척도 6번(말 :속도/양), 7번(언어, 사고의 장애), 10번(용모)에서 점수변화율에 유의한 차이가 있었다. T4 및 TSH의 변화와 YMRS의 변화사이에는 뚜렷한 관련성을 찾을 수 없었다. 4) 이상의 결과를 토대로, 갑상선 호르몬의 변화가 조증 증상 변화 또는 조증 아형 분류의 자료로서 활용될 가능성이 있음을 제시하였다.

본 논문에서는 고에너지 엑스선(6 MV X선)을 조사한 갑상선의 소포세포막 모델에서 막의 두께차이, 고정전달자[VP-AN% (w/ w)]의 농도차이, OH-이온의 농도차이가 세포내부와 세포외부사이로 갑상선호르몬의 구성성분인 요오드이온의 농도차이로 발생하고 갑상선호르몬의 생성량에 영향을 미치는데 이러한 영향을 구명하기위해서 소포의 세포막을 통한 요오드의 선택적 투과전달 특성에 대하여 연구하였다. 이 실험에 사용한 세포막 모델은 피리딘 양이온을 고정전달자로 한 poly(4-vinylpyridine- co-acrylonitrile :VP-AN)분말을 인장강도의 강화용인 polysulfone과 결합시킨 불균질의 복합막을 사용하였다. 고정전달자[VP-AN% (w/ w)]의 농도차이(0~62 %)에서 36.5 ℃로 방사선을 조사한 소포의 고분자 막(세포막모델)은 형태학적 변화인 인장강도가 비 조사된 세포막모델보다 약 1.2 ~ 1.8배 정도 감소되었다. 방사선을 조사한 갑상선의 소포세포막모델 [2mole AN%(w/w)]에서 막의 두께차이, 고정전달자[VP-AN% (w/ w)]의 농도차이, OH-이온의 농도 차이로 발생하는 요오드이온의 선택적 투과플럭스는 비 조사된 세포막모델보다 막의 두께가 변화 할 때 각각 약 2.1 ~ 4.5배, 약 2.2 ~ 2.5배, 약 2.1 ~ 2.67배 정도 감소되었다. 결국 방사선조사로 인해서 갑상선의 소포세포막에서 요오드이온의 선택적 투과 전달기능이 비정상적으로 되어 세포장해가 발생하고 갑상선호르몬의 생성량 감소도 동반하게 되었다고 사료됐다.

Objectives : In present study, we investigated a therapeutic effect of Astragali Radix on hypothyroidism rat model induced by 6-Propyl-2-thiouracil (PTU). Methods : Six-week-old male Sprague-Dawley rats were divided into five groups : Group one included the normal mice. Group two was administrated PTU. Group three and four were administrated the aqueous extract of Astragali Radix 150 and 300 mg/kg before start of PTU treatment. Group five (Positive control) was administrated with levothyroxine 0.5 mg/kg. During this moment the body weight, liver $H_2O_2$ and catalase (CAT) amount, serum thyroid hormone, serum asparte aminotransferase (AST) and alanine aminotransferase (ALT), gland weights were measured with histopathological changes of thyroid glands. These results were compared with levothyroxine 0.5 mg/kg treated rats. Results : The PTU treatment lead to marked decreases of body weight, level of thyroid hormone in serum and liver CAT activation. Also, PTU treatment increased thyroid gland weight, thyroid gland hormone TSH, liver $H_2O_2$ amount and level of AST in serum. On the other hands, the administration of Astragali Radix extract increased body weight gains and ameliorated histopathological changes of thyroid such as hyperplasia of follicular cells with of follicular colloid contents and sizes. In addition, the administration of Astragali Radix extract increased level of $T_4$ in serum, CAT activation in liver. Moreover, the administration of Astragali Radix extract decreased levels of TSH and AST in serum and $H_2O_2$ amount in liver Conclusions : This study suggests that Astragali Radix extract has therapeutic effects on hypothyroidism via promoting thyroid hormone production.

Transgender is the severe type of gender identity disorder. The prevalence rate of transgender is reported to occur to about 1 out of 50,000 men, and about 1 out of 10,000 women. As for Korea, it is estimated to have about 1400 transgender patients. Lately, not only the numbers of them are increasing but also they are influencing our society increasingly. As for female transgender patients, they take female hormone for a long term before and even after the operation to maintain their physical identity of female. We have analyzed insulin like growth factor-1(IGF-1), insulin like growth factor protein binding-3(IGFBP-3), female hormone, male hormone and thyroid hormone in female transgender patients who have undergone the gender reassignment operation. We examined the changes of hormone level due to having female hormone steadily, and also examined how the steady use of the hormone could affect body organs. As for IGF-1, it showed significantly low in the female transgender group compared to control ($319.30{\pm}37.4$ vs $539{\pm}55.0$, p<0.05). As for IGFBP-3, there was no significant difference ($2859{\pm}200.3$ vs $2607{\pm}262.5$, p>0.05). As for female hormone, there was no significant differences in FSH($13.42{\pm}13.8$ vs $8.95{\pm}3.5$, p>0.05), estradiol($104.41{\pm}97.1$ vs $121.68{\pm}60.2$, p>0.05), and LH($7.62{\pm}5.6$ vs $7.4{\pm}3.3$, p>0.05). Even in comparison of testosterone, there was no significant differences($0.23{\pm}0.09$ vs $0.33{\pm}1.33$, p>0.05). As for thyroid hormone, there was no significant differences in TSH and free T4($1.34{\pm}0.94$ vs $1.71{\pm}0.12$, $1.4{\pm}0.37$ vs $1.46{\pm}0.17$, p>0.05). Therefore, this study concludes that apart from the decreased level of IGF-1, the possible endocrine side-effect problem due to female hormone seems to be low because there was no differences of female, male, and thyroid hormone level compared with normal female. Further study will be required in metabolic change including bone metabolism occurred by decrease level of IGF-I.
