| 영문 | thymus(gland) | 한글 | 가슴샘 |
|---|---|---|---|
| 설명 | 가슴의 앞 위쪽에 위치한 림프성 장기로서, 사춘기에 최고의 무게에 달했다가 이후에 퇴축한다. 이것은 세포매개 면역(cell-mediated immunity: 주로 T-림프구에 의해 일어나며, 자기와 다른 세포에 대한 인식과 이식거부반응에 관여함)기능의 발달과 성숙에 필요한 장기이며, 회백적색으로 보통 정중면에서 결합조직에 의해 결합된 두 개의 엽으로 되어 있다. 가슴샘은 상피세포, 림프구, 가슴샘세포로 구성되어 있으며 전구세포가 가슴샘에 이행하여 림프구로 분화되고, 그 대부분은 파괴되나 나머지는 T림프구를 형성한다. 가슴샘은 또한 호르몬 유사물질인 thymine, thymopoietin, thymosin 등을 분비한다. |

| 영문 | thyroid gland | 한글 | 갑상샘 |
|---|---|---|---|
| 설명 | 사람의 몸에서 가장 큰 내분비샘으로 목의 앞쪽, 아래쪽에 위치하고 있으며 2엽으로 구성되어 있다. 각 엽은 기관의 양쪽에 있으며 좁은 잘룩에 의해 앞에서 연결되어 있다. 갑상샘호르몬인 티록신(thyroxine)을 분비하고 저장하며, 필요에 따라 방출한다. 또한 갑상샘은 티로칼시토닌(thyrocalcitonin)도 분비한다. 병적인 상태에서 크기가 대개 증가하고, 일부에서는 도리어 위축되며, 통증을 나타내기도 한다. |

|---|---|---|---|
| 설명 | 침샘의 하나. 침샘이란, 음식을 삼킬 때 입안으로 분비되어 음식물이 잘게 씹히는데 도움을 주며, 음식물을 소화하는데 이용되는 효소를 가지고 있는 침을 생산하는 곳을 말함. 크게 3가지의 침샘을 가지고 있으며, 위치와 모양은 옆의 그림과 같다.  |

| 영문 | endocrine gland | 한글 | 내분비샘 |
|---|---|---|---|
| 설명 | 신체의 내부로 분비가 되어서 다른 세포의 기능이나 활성의 변화를 일으키는 물질인 호르몬을 분비하는 곳을 이르는 말이다. 대표적인 내분비샘은 갑상샘, 부갑상샘, 부신, 이자, 뇌하수체, 난소, 고환, 솔방울샘, 가슴샘 등이다. 마지막에 나오는 2개의 기관은 내분비 기능을 하는 것으로 생각이 되지만 확실히 그것이 무슨 기능을 하는 지에 대해선 아직까지 정확하게 밝혀지지 않고 있다.  |

|---|---|---|---|
| 설명 | 콩팥위에 존재하는 피라밋모양의 구조물. 겉질과 속질로 되어 있으며 호르몬의 분비가 주역할이다.  |

| thymus gland | A bilaterally symmetric lymphoid organ situated in the anterior superior mediastinum. Each of its two lobes consists of an outer zone, the cortex, relatively rich in lymphocytes (thymocytes), and an inner zone, the medulla, relatively rich in epithelial cells. The thymus is the site of the production of T-lymphocytes. The thymus reaches its maximal development at about puberty and then undergoes a gradual process of involution resulting in a slow decline of immune function throughout adulthood. (12 Dec 1998) |

| ribonuclease h, calf thymus | <enzyme> A ribonuclease that specifically cleaves the RNA moiety of RNA:DNA hybrids. It has been isolated from a wide variety of prokaryotic and eukaryotic organisms (particularly calf thymus) as well as retroviruses. Registry number: EC 3.1.26.4 (12 Dec 1998) |
| congenital aplasia of thymus | diGeorge syndrome |
| cortex of thymus | The outer part of a lobule of the thymus; it surrounds the medulla and is composed of masses of closely packed lymphocytes. (05 Mar 2000) |
| hypoplasia of the thymus and parathyroids | Also known as the digeorge syndrome (dgs), this disorder is characterised by (1) low blood calcium levels (hypocalcaemia) due to underdevelopment (hypoplasia) of the parathyroid glands needed to control calcium; (2) underdevelopment (hypoplasia) of the thymus, an organ behind the breastbone in which lymphocytes mature and multiply; and (3) defects of the outflow tracts from the heart. most cases of dgs are due to a microdeletion in chromosome band 22q11.2. A small number of cases have defects in other chromosomes, notably 10p13. Named after the american paediatric endocrinologist angelo digeorge. Another name for dgs is the third and fourth pharyngeal pouch syndrome (since the faulty structures in dgs are embryologically derived from the third and fourth pharyngeal pouches). (12 Dec 1998) |
| thymus | <anatomy> The lymphoid organ in which T lymphocytes are educated, mature and multiply. It is composed of stroma (thymic epithelium) and lymphocytes, almost entirely of the T-cell lineage. In mammals the thymus is just anterior to the heart within the rib cage, in other vertebrates in rather undefined regions of the neck or within the gill chamber in teleost fish. The thymus regresses as the animal matures. (18 Nov 1997) |
| thymus and parathyroids, hypoplasia of | See third and fourth pharyngeal pouch syndrome. (12 Dec 1998) |
| thymus-dependent zone | <anatomy> Mid cortical region of lymph node, area that is particularly depleted of T lymphocytes in thymectomised animals and is referred to as the thymus dependent area. (18 Nov 1997) |
| thymus derived lymphocyte | <haematology, immunology> A class of lymphocytes, so called because they are derived from the thymus and have been through thymic processing. Involved primarily in controlling cell-mediated immune reactions and in the control of B-cell development. The T-cells coordinate the immune system by secreting lymphokine hormones. There are 3 fundamentally different types of t cells : helper, killer, and suppressor. Each has many subdivisions. T-cells are also called t lymphocytes. They bear T-cell antigen receptors (CD3) and lack Fc or C3b receptors. Major T-cell subsets are CD4 (mainly helper cells) and CD8 (mostly cytotoxic or suppressor T-cells). Uncontrolled proliferation of this type of cell gives rise to T-cell leukaemia/lymphoma. (21 Jun 1999) |
| thymus extracts | Extracts of the thymus that contain specific, but uncharacterised factors or proteins with specific activities; three distinct substances are already known: thymotoxin, thymin and thymosin. (12 Dec 1998) |
| thymus hormones | Humoral factors secreted by the thymus gland. They participate in the development of the lymphoid system and the maturation of the cellular immune response. (12 Dec 1998) |
| thymus hyperplasia | Enlargement of the thymus. A condition described in the late 1940's and 1950's as pathological thymic hypertrophy was status thymolymphaticus and was treated with radiotherapy. Unnecessary removal of the thymus was also practiced. It later became apparent that the thymus undergoes normal physiological hypertrophy, reaching a maximum at puberty and involuting thereafter. The concept of status thymolymphaticus has been abandoned. Thymus hyperplasia is present in two thirds of all patients with myasthenia gravis. (12 Dec 1998) |
| thymus-independent antigen | An antigen that does not require T helper cell activation in order for the host's B-cells to be stimulated. Repeating polymers such as polysaccharides are examples of T-independent antigens. (05 Mar 2000) |
| thymus treatment | Treatment of disease by administration of extracts of thymus gland. (05 Mar 2000) |
| lobules of thymus | Areas of thymic tissue 0.5 to 2 mm in diameter with a cortex and medulla. Synonym: lobuli thymi. (05 Mar 2000) |
