まとめ
甲状腺刺激ホルモン(TSH)、遊離サイロキシン(FT4)、遊離トリヨードサイロニン(FT3)を含む甲状腺ホルモンレベルは、インドの成人において年齢および性別によって異なる。本研究は、これらの甲状腺機能検査の年齢別および性別別基準範囲を確立する。
科学分野:
- 内分泌学
- 甲状腺学
- 臨床生化学
背景:
- 甲状腺の生理機能は、年齢および性別によって影響を受ける。
- インド特有の甲状腺機能検査(TFT)の基準範囲は、十分に定義されていない。
- TFTの正確な解釈には、年齢および性別で層別化されたデータが必要である。
研究 の 目的:
- インドの人口におけるTSH、FT4、FT3の年齢別および性別別の基準限界値を決定すること。
- 甲状腺機能検査(TFT)の更新された基準範囲を、甲状腺機能正常(euthyroid)のインドの成人に対して確立すること。
- インドにおけるTFTの解釈改善のためのデータを提供すること。
主な方法:
- 多施設共同、地域ベースの横断研究。
- インドの5地域から募集した甲状腺機能正常(euthyroid)成人5,812名を対象とした。
- 標準化された化学発光プラットフォームおよびノンパラメトリックパーセンタイル法を用いて、朝の空腹時検体を測定した。
主要な成果:
- 中央値TSHは女性の方が男性よりも高く、年齢とともに増加した。
- FT4およびFT3レベルは、年齢とともにわずかに低下した。
- TSHの97.5パーセンタイル値は年齢とともに増加し、全年齢層で女性の方が高い上限値が観察された。
結論:
- 年齢および性別は、インドの成人における甲状腺機能検査の結果に有意に影響を与える。
- TFTの正確な解釈には、確立された年齢別および性別別の基準範囲が不可欠である。
- 本研究は、インドにおける甲状腺疾患の診断を最適化するための不可欠なデータを提供する。

Synthesis and Regulation of Thyroid Hormones
7.0K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Functions of Thyroid Hormones
4.9K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

The Thyroid Gland
6.5K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Major Hormones and Their Functions
1.6K
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

Target Cell Response to Hormones
5.0K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

The Parathyroid Glands

The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...
