|---|---|---|---|
| 설명 | 새로 생긴 물질이라는 뜻이다. 이것은 다른 말로 “종양(tumor)”이라고도 하는 데, 실제로 이들의 명확한 뜻은 서로 다르다. 종양이라는 말은 “그 크기가 1cm가 넘는 일종의 혹”을 말하는 것으로 피부과에서는 이보다 작은 혹을 구진이라고 하여 구별하여 부른다. 하지만, 이것은 또한 피부뿐만 아니라 신체내 어디에서든 생길 수 있으므로 모두 통칭하여 종양이라고 부른다. 이에 비해 “신생물”은 신체내 없던 것이 새로 생겨났다는 뜻으로 붙인 말이다. 그러나, 이 둘의 관계를 명확히 규정짓지 않고 있으며 대개 같은 뜻으로 혼용된다. 신생물에는 “양성(benign)”과 “악성(malignant)”이 있다. 이 둘의 구별은 여러 가지 기준에 따르지만, 때로는 구별이 어려울 때도 있다. 대개 양성은 생명단축을 잘 일으키지 않는 것으로 치료후에 재발도 잘 하지 않는다. 이에 비해 악성은 재발뿐만 아니라 다른 기관으로 옮겨가서 같은 병변이 발생하는 “전이(metastasis)”현상도 일어난다. 따라서 생명을 단축시키는 경우가 많으며, 대개 치료가 어렵다. |

| 설명 | 인체의 장기나, 병적인 모양, 종양의 위치, 림프절의 비대 등에 대한 진단을 내리기 위해 시행하는 방사선학적인 검사방법이다. 현재 많이 쓰이고 있는 컴퓨터단층촬영술(CT: computerized tomography)과는 다른 방법으로 시행하며, 그 해상도가 컴퓨터단층촬영보다는 뛰어나 비록 고가이긴 하지만, 많이 쓰이고 있다. 또한 인체에 무해하고, 여러 가지 면에서 사람을 단층으로 분리시켜 볼 수 있는 등 장점이 많다. 단점은 심장박동기를 설치한 사람이나, 주위에 장을 띠는 물체를 몸에 지니고 있는 중환자 등에서는 이용할 수 없고, 복부장기에 대한 진단에는 컴퓨터단층촬영보다 불리한 것으로 되어 있으며, 무엇보다 설치비와 그 시술비가 비싸다는데 가장 큰 단점이 있다. |

| gallium | <chemistry, element> A rare metallic element, found in certain zinc ores. It is white, hard, and malleable, resembling aluminium, and remarcable for its low melting point (86 F, 30C). The element was predicted with most of its properties, under the name ekaluminium, by the Russian chemist Mendelejeff, on the basis of the Periodic law. This prediction was verified in its discovery by the French chemist Lecoq de Boisbaudran by its characteristic spectrum (two violet lines), in an examination of a zinc blende from the Pyrenees. Atomic weight: 69.9 Abbreviation: Ga Origin: NL, fr. L. Gallia France. Source: Websters Dictionary (01 Mar 1998) |
