As the number of obese patients increases, childhood obesity also increases and it is recognized as a big problem because it increases the incidence of hypertension, hyperlipidemia, diabetes and metabolic syndrome. Although thyroid hormone abnormalities sometimes exist in obese patients without thyroid disease, there is still much controversy on the impact of obesity on thyroid hormone test results. Accordingly, the present study investigated the correlation between obesity and thyroid hormone concentrations in children with normal thyroid function. In the present study, 356 patients aged 6-18 years who visited the Chosun University Hospital were randomly selected, after exclusion of those with thyroid disease, diabetes mellitus, kidney disease, those with a history of smoking and drinking, and those taking steroids or lipid lowering agents. There were no significant differences in levels of thyroid stimulation hormone (TSH) and free thyroxin (fT4) between males and females. The patients were divided into groups based on serum TSH concentration: group A with TSH < 4.0 μIU/mL and group B with TSH ≥ 4.0 μIU/mL (upper level of normal range). BMI z score, ALT, rGTP, and total cholesterol were significantly higher in group B. Multiple regression analysis adjusted for age, gender, birth weight, and pubertal development showed that TSH and BMI z score were positively correlated, while fT4 was not correlated with other factors.

Amphiprion melanopus의 난발생과 자치어의 형태학적 발달에 대한 기초 조사와 함께, 먹이생물과 갑상선호르몬이 자치어의 성장과 체색에 미치는 영향을 조사하였다. 수정 후, 부화까지 총 168시간이 소요되었다. 갓 부화 자어의 크기는 평균 mm 으며, 대부분의 자어는 부화 후 경과일 수에 따라 체색 변화(변태)를 나타내었다; DAH(days afterhatching) 10: 체색 흑화, DAH 15~20: 3개의 흰 줄무늬 출현, DAH 30

조피볼락 갑상선 여포의 원시세포는 모체내 부화자어의 구강 아래쪽에 존재하는 때의 원형 여포 안에 존재하였다. 갑상선 여포는 구강 연골조직 아래쪽 제 1, 2,3 도입새동맥 부근에 흩어져 존재하고, 출산 직후에는 13개 정도로 분화되어 있었다. 갑상선 여포의 수는 출산 직후(전장 6.3 mm)에 개체당 1.60.8개였으며, 치어기로 전환하는 30일째에는 17.02.1개, 50일째(전장 13.2 mm)에는 32.56.9개로 그 수가 매우 많아졌다. 갑상선
