| 영문 | nerve cell | 한글 | 신경세포 |
|---|---|---|---|
| 설명 | 신경세포는 올바른 신경전달을 위한 각 부분별로 나뉘어져 있다. 신경세포에서는 전해져오는 자극을 전기적인 신호로 바뀌어 보내거나 받게 된다. 이런 전기적인 현상은 각 신경세포내에 존재하는 각 이온채널(ion channel: ion이란 나트륨, 칼륨 등을 지칭하는 말들로써, 이들이 세포막에 의해 나뉘어질 때 생기는 전압차가 전기적 자극을 일으키고 유지하는데 결정적인 역할을 한다)들의 작용에 의해 이루어지게 된다. |

|---|---|---|---|
| 설명 | 신경세포 사이에서 그물구조를 이루며 이를 지지하는 조직. 신경아교세포는 신경모세포와 갈라진 아교모세포가 다시 여러 형태로 분화-성장한 것이다. 뇌실이나 척수중심관의 벽을 덮고 원주상 또는 입방형이며, 초기에는 유리면에 섬모가 있다. 대형세포는 별뇌실막세포는 아교세포라고 하며, 신경세포나 신경섬유 사이에 산재한다. 그 외에 희소돌기아교세포도 포함된다. |

|---|---|---|---|
| 설명 | 일반적으로 상피조직에서 이미 있던 상피세포가 손상을 받아 사멸하면 매꿔지는 그 밑에 있는 미분화세포 예를 들면, 기관지 내표면을 덮는 중층 원주 상피의 기저에 있는 작은 미분화 상피 세포. |

| 영문 | stem cell | 한글 | 줄기세포, 간세포 |
|---|---|---|---|
| 설명 | 자기 복제를 하여 자신을 존속시키면서 한편으로는 증식과 분화를 하여 새로운 세포를 형성하는 세포로서 조혈줄기세포가 대표적이다. 조혈줄기세포는 골수에 있는 세포로서 모든 혈구세포가 여기에서 분화되어 발생한다. |

| 영문 | renal cell carcinoma | 한글 | 콩팥세포암종 |
|---|---|---|---|
| 설명 | 콩팥에 생긴 원시콩팥조직에서 발생한 암. 주로 원시세뇨관조직에서 발생한다. 대표적인 세포조직형은 염색시 세포질이 맑게 비어보이는 맑은세포암종이다. 치료는 수술과 항암화학요법이며 아주 드물지만 저절로 낫는 경우도 있는 것으로 보고되어 있다. |

| giant cell tumour | <radiology> Osteoclastoma, GCT, any age, typically 20-35, site: metaphysis into epiphysis, 50% at knee (distal femur, proximal tibia), long bones, patella, spine, eccentric, expansile, with or without soap bubble appearance, treatment: curette, fill with methacrylate, 10% recur, a few are premalignant or malignant, cannot determine malignancy by XR (12 Dec 1998) |
|---|---|
| giant cell tumour of bone | A bone tumour composed of cellular spindle-cell stroma containing scattered multinucleated giant cells resembling osteoclasts. The tumours range from benign to frankly malignant lesions. The tumour occurs most frequently in an end of a long tubular bone in young adults. (12 Dec 1998) |
| giant cell tumour of tendon sheath | A nodule, possibly inflammatory in nature, arising commonly from the flexor sheath of the fingers and thumb; composed of fibrous tissue, lipid-and haemosiderin-containing macrophages, and multinucleated giant cells. Synonym: localised nodular tenosynovitis. (05 Mar 2000) |
| Merkel cell tumour | A rare malignant cutaneous tumour seen in sun-exposed skin of elderly patients composed of dermal nodules of small round cells with scanty cytoplasm in a trabecular pattern; the tumour cells contain cytoplasmic dense core granules resembling neurosecretory granules seen in Merkel cells. Synonym: primary neuroendocrine carcinoma of the skin, trabecular carcinoma. (05 Mar 2000) |
| granular cell tumour | Unusual tumour affecting any site of the body, but most often encountered in the head and neck. Considerable debate has surrounded the histogenesis of this neoplasm; however, it is considered to be a myoblastoma of, usually, a benign nature. It affects women more often than men. When it develops beneath the epidermis or mucous membrane, it can lead to proliferation of the squamous cells and mimic squamous cell carcinoma. (12 Dec 1998) |
| granulosa cell tumour | An ovarian tumour originating in the cells of the primordial membrana granulosa of the graafian follicle. It may be associated with excessive production of estrin, inducing endometrial hyperplasia with menorrhagia. It can be benign or malignant. It is soft, solid, white or yellow, and consists of small round cells sometimes enclosing call-exner bodies. Larger lipid-containing cells may be present. Granulosa cell tumours are seen in women of all ages. Treatment depends on the age of the patient and the extent of the disease. (12 Dec 1998) |
| hilar cell tumour of ovary | A small benign masculinizing ovarian tumour derived from hilar cells, which resemble Leydig cells of the testis. (05 Mar 2000) |
| Hurthle cell tumour | A neoplasm of the thyroid gland composed of polyhedral acidophilic cells, thought by some to be oncocytes; it may be benign or malignant, the behaviour of the latter depending on the general microscopic pattern, whether follicular, papillary, or undifferentiated. See: Hurthle cell adenoma. Synonym: Hurthle cell carcinoma. (05 Mar 2000) |
| sertoli cell tumour | A rare benign tumour of the testis that histologically resembles the foetal testis. There are three varieties: diffuse stromal, mixed (stromal and epithelial), and tubular (epithelial). Sertoli cells in the epithelial elements may produce oestrogen and cause feminization. (12 Dec 1998) |
| sertoli-leydig cell tumour | An ovarian tumour usually of low-grade malignancy occurring most frequently in the third and fourth decades, with 75% seen in women under 40. It is rare, representing less than .02% of ovarian cancers. The tumour typically produces androgens with virilization being noted in 70-85% of the patients. (holland et al., cancer medicine, 3d ed, p1684) (12 Dec 1998) |
| interstitial cell tumour of testis | <tumour> A small benign tumours of the testis that often produce testosterone, causing endocrine symptoms. Synonym: interstitial cell tumour of testis. (05 Mar 2000) |
| tumour cell | <oncology> Cell derived from a tumour in an animal. Refers to a tumour causing malignant cell and not an adventitious normal cell. Loosely, a transformed cell able to give rise to tumours. (18 Nov 1997) |
| tumour stem cell assay | <investigation> A cytologic technique for measuring the functional capacity of tumour stem cells by assaying their activity. It is used primarily for the in vitro testing of antineoplastic agent. (12 Dec 1998) |
| leydig cell tumour | The most common nongerminal tumour of the testis, derived from the leydig cells. It is rarely malignant. This tumour appears among 1-3% of testicular tumours and although they may be seen in children, the median age of appearance is 60 years. They are sometimes seen in women as ovarian tumours. Clinically, symptoms are usually related to the endocrine abnormalities induced by this tumour. (12 Dec 1998) |
| T-cell-rich, B-cell lymphoma | <tumour> A B-cell lymphoma in which more than 90% of the cells are of T-cell origin, masking the large cells that form the neoplastic B-cell component. See: adult T-cell lymphoma. (05 Mar 2000) |
