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

|---|---|---|---|
| 설명 | 콩팥의 깔때기 또는 술잔에 형성된 돌을 말하며 요저류, 감염, 요량 감소 등이 있을 때 잘 나타나는 것으로 알려져 있다. 증상은 옆구리나 측복부에 갑자기 생기는 심한 동통, 육안적이나 현미경적 혈뇨, 척추갈비뼈각 압통이 있을 수 있으나 경우에 따라 증상이 없이 우연하게 발견되는 수도 있다. 진단은 요검사나 요배양검사, 혈액검사, 방사선검사를 이용해서 하며 치료방침은 그 돌의 활성도에 따라 다량의 수분 섭취나 진통제를 사용해서 자연배출을 유도하거나 체외충격파 쇄석술, 내비뇨기과적 쇄석술, 수술요법, 내과적 요법을 사용한다. 돌의 활성도란 동통, 폐색현상, 돌의 크기 증가 여부, 새로운 돌의 발생에 의하여 결정되어진다. |

| 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) |
