|---|---|---|---|
| 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. |

| nuclear RNA | <molecular biology> The nucleus contains RNA that has just been synthesised, but in addition there is some that seems not to be released or is only released after further processing, the heterogenous nuclear RNA (hnRNA) and small RNA molecules associated with protein to form small nuclear ribonucleoproteins. (18 Nov 1997) |

| RNA, heterogeneous nuclear | Nuclear nonribosomal RNA larger than about 1000 nucleotides, the mass of which is rapidly synthesised and degraded within the cell nucleus. Some heterogeneous nuclear RNA may be a precursor to mRNA. However, the great bulk of total hnrna hybridises with nuclear DNA rather than with mRNA. (12 Dec 1998) |
|---|---|
| RNA, nuclear | RNA molecules found in the nucleus either associated with chromosomes or in the nucleoplasm. (12 Dec 1998) |
| RNA, small nuclear | Short chains of RNA found in the nucleus. Their function is to remove the introns (nontranslated intervening sequences) from mRNA precursors, thereby bringing the two exons (coding segments) together into correct juxtaposition for enzymatic splicing at the correct point. The resulting mRNA is now ready to leave the nucleus. (12 Dec 1998) |
| heterogeneous nuclear RNA | An ill-defined form of RNA, of high molecular weight, that never leaves the nucleus and is thought to be the precursor of messenger RNA. (05 Mar 2000) |
| heterogenous nuclear RNA | <molecular biology> Originally identified as a class of RNA, found in the nucleus but not the nucleolus, which is rapidly labelled and with a very wide range of sizes, 2-40 kilobases. It represents the primary transcripts of RNA polymerase II and includes precursors of all messenger RNAs from which introns are removed by splicing. (18 Nov 1997) |
| small nuclear RNA | <molecular biology> A nucleic acid found in all living cells. Plays a role in transferring information from DNA to the protein-forming system of the cell. (16 Dec 1997) |
| U1 small nuclear RNA-(guanosine-N2)-methyltransferase | <enzyme> A trans-active non-small nuclear ribonucleoprotein; facilitates the formation of the m3g cap Registry number: EC 2.1.1.- Synonym: u1 snrna(g-n2)mtase (26 Jun 1999) |
| U6 small nuclear RNA methyltransferase | <enzyme> Methylates gamma-phosphate residues in rnas; distinct from u6 snrna n6-adenosine methyltranferase; mw 130 kD; from hela cells Registry number: EC 2.1.1.- Synonym: u6 snrna capping enzyme (26 Jun 1999) |
| receptors, cytoplasmic and nuclear | Proteins in the cytoplasm or nucleus that specifically bind signalling molecules and trigger changes which influence the behaviour of cells. The major groups are the steroid hormone receptors, which usually are found in the cytoplasm, and the thyroid hormone receptors, which usually are found in the nucleus. Receptors, unlike enzymes, generally do not catalyze chemical changes in their ligands. (12 Dec 1998) |
| Remak's nuclear division | <cell biology> An unusual form of nuclear division, in which the nucleus simply constricts, rather like a cell without chromosome condensation or spindle formation. Partitioning of daughter chromosomes is haphazard. Observed in some Protozoa. (18 Nov 1997) |
| Pelger-Huet nuclear anomaly | Congenital inhibition of lobulation in the nuclei of neutrophilic leukocytes; most cells present band or bilobulate appearance, and only an occasional cell is trilobed; it is not associated with disease, but may be confused with leukocyte "shift to left"; autosomal dominant inheritance. (05 Mar 2000) |
| ribonucleoproteins, small nuclear | Highly conserved nuclear RNA-protein complexes that function in RNA processing in the nucleus, including pre-mRNA splicing and pre-mRNA 3'-end processing in the nucleoplasm. The u3 snrnp is localised in the nucleolus, where it aligns into base pairs with the 28s rrna precursor in a still unidentified region and functions in pre-rrna processing. The u7 snrnp aligns into base pairs with a conserved sequence in the 3'-end of histone pre-mRNA and is an essential cofactor for the cleavage that creates the mature nonadenylated 3'-end. (12 Dec 1998) |
| rod nuclear cell | <pathology> Immature neutrophils released from the bone marrow reserve in response to acute demand. (18 Nov 1997) |
| 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) |
| proliferating cell nuclear antigen | Acidic nuclear protein (33 kD) highly expressed in dividing cells. Interacts with D type cyclins. (18 Nov 1997) |
