| 설명 | 방사성을 띠는 핵물질을 이용하여 의학에 응용하는 학문. 대개 인체에 큰 해가 없는 방사선물질을 사용하며, 반감기가 짧아 사용후에도 큰 해가 없다. 이런 핵의학적 물질을 이용한 핵의학적 진단의 가장 큰 장점은 생체내에서 일어나는 그 기관의 실제적인 기능을 알아볼 수 있다는 데 있다. 흔히 접하는 X-선을 이용한 진단방법은 단지 그 순간만의 영상을 접하여 실제로 보이는 부위가 얼마나 기능을 수행하는지 알 수 없는 단점이 있으나, 핵의학에서는 실제적인 기능의 정도에 따라 영상이 나오게 되므로 기능판별에 아주 유리하다. 하지만, 정확한 판별력이 있는 영상을 얻기에는 부족하다. 또한 핵의학은 진단외의 치료에도 사용되는데, 예를 들어 갑상샘종양의 경우 여러 곳에 이미 전이가 되어 있을 경우 방사선핵종을 이용하여 다른 곳에 큰 부작용없이 치료가 가능하다. |

| 설명 | 다른 말로 MRI=Magnetic Resonance Imaging 자기공명영상이라고도 한다. 인체의 장기나, 병적인 모양, 종양의 위치, 림프절의 비대 등에 대한 진단을 내리기 위해 시행하는 방사선학적인 검사방법이다. 현재 많이 쓰이고 있는 컴퓨터단층촬영(CT=computerized tomography)과는 다른 방법으로 시행하며, 그 해상도가 컴퓨터단층촬영보다는 뛰어나 비록 고가이긴 하지만, 많이 쓰이고 있다. 또한 인체에 무해하고, 여러 가지 면(plane)에서 사람을 단층시켜 볼 수 있다. 단점은 심장박동기를 설치한 사람이나, 주위에 자장을 띠는 물체를 몸에 지니고 있는 중환자 등에서는 이용할 수 없고, 복부장기에 대한 진단에는 컴퓨터단층촬영보다 떨어지는 것으로 되어 있다. |

| cistern of nuclear envelope | The space between the internal and external membranes of the nuclear envelope; may be continuous in places with cisterns of the endoplasmic reticulum. Synonym: cistern of nuclear envelope, perinuclear space. (05 Mar 2000) |

| nuclear envelope | <cell biology> Membrane system that surrounds the nucleus of eukaryotic cells. Consists of inner and outer membranes separated by perinuclear space and perforated by nuclear pores. The term should be used in preference to the term nuclear membrane which is potentially very confusing. (18 Nov 1997) |

| viral envelope | The outer structure that encloses the nucleocapsids of some viruses; may contain host material. (05 Mar 2000) |
| viral envelope proteins | Layers of protein which surround the capsid in animal viruses with tubular nucleocapsids. The envelope consists of an inner layer of lipids and virus specified proteins also called membrane or matrix proteins. The outer layer consists of one or more types of morphological subunits called peplomers which project from the viral envelope; this layer always consists of glycoproteins. (12 Dec 1998) |
| corneocyte envelope | An electron-dense, 10-15 nm thick layer of highly cross-linked protein on the cytoplasmic surface of the cell membrane of epidermal corneocytes; it is highly resistant to proteolytic agents. Synonym: subplasmalemmal dense zone. (05 Mar 2000) |
| HIV envelope protein gp120 | External envelope protein of the human immunodeficiency virus which is encoded by the HIV env gene. It has a molecular weight of 120,000 kD and contains numerous glycosylation sites. Gp120 binds to cells expressing CD4 cell-surface antigens, most notably t4-lymphocytes and monocytes/macrophages. Gp120 has been shown to interfere with the normal function of CD4 and is at least partly responsible for the cytopathic effect of HIV. (12 Dec 1998) |
| HIV envelope protein gp160 | An envelope protein of the human immunodeficiency virus that is encoded by the HIV env gene. It has a molecular weight of 160,000 kD and contains numerous glycosylation sites. It serves as a precursor for both the HIV envelope protein gp120 and the HIV envelope protein gp41. (12 Dec 1998) |
| HIV envelope protein gp41 | Transmembrane envelope protein of the human immunodeficiency virus which is encoded by the HIV env gene. It has a molecular weight of 41,000 and is glycosylated. The n-terminal part of gp41 is thought to be involved in cell fusion with the CD4 antigens of t4 lymphocytes, leading to syncytial formation. Gp41 is one of the most common HIV antigens detected by immunoblotting. (12 Dec 1998) |
| surface envelope model | <biology> A way of treating the hydrodynamics of a ciliary field by considering the whole surface of the ciliate to have an undulating surface. The undulations arise because of metachronism. (18 Nov 1997) |
| envelope | 1. <virology> Lipoprotein outer layer of some viruses derived from plasma membrane of the host cell. 2. <microbiology> The plasma membrane and cell wall complex of a bacterium. (11 Nov 1997) |
| envelope conformation | See: Haworth conformational formulas of cyclic sugars. (05 Mar 2000) |
| envelope flap | A mucoperiosteal flap retracted from a horizontal incision along the free gingival margin. (05 Mar 2000) |
| ambient cistern | <anatomy, vein> An expansion of the subarachnoid space extending forward between the corpus callosum and the thalamus; it encloses the internal cerebral veins which caudally join to form the vena magna cerebri (Galen's vein). Synonym: ambient cistern, Bichat's canal, Bichat's foramen, cistern of great vein of cerebrum, cisterna ambiens, cisterna superioris, cisterna venae magnae cerebri, superior cistern. (05 Mar 2000) |
| basal cistern | A dilation of the subarachnoid space in front of the pons, where the arachnoid membrane stretches across between the two temporal lobes over the base of the diencephalon. See: interpeduncular fossa. Synonym: cisterna interpeduncularis, basal cistern, cisterna basalis, cisterna cruralis, Tarin's space. (05 Mar 2000) |
| Pecquet's cistern | A dilated sac at the lower end of the thoracic duct into which the intestinal trunk and two lumbar lymphatic trunks open; it occurs inconstantly and when present is located posterior to the aorta on the anterior aspect of the bodies of the first and second lumbar vertebrae. Synonym: ampulla chyli, chyle cistern, chylocyst, Pecquet's cistern, Pecquet's reservoir, receptaculum chyli, receptaculum pecqueti. (05 Mar 2000) |
| cerebellomedullary cistern | The largest of the subarachnoid cisterns between the cerebellum and the medulla oblongata; may be divided into a dorsal cistern located between the cerebellum and dorsal surface of the medulla (cisterna magna) and a lateral cistern located between the cerebellum and the lateral aspect of the medulla. Synonym: cisterna cerebellomedullaris, cisterna magna. (05 Mar 2000) |
