| 설명 | 결정성의 산. 2, 6, 8-trioxypurine. 화학식은 C5H4N4O3로 사람과 동물의 오줌에서 얻을 수 있다. 핵의 대사산물의 하나. 물, 알콜, 에테르(ether)에는 거의 녹지 않으나 알칼리염의 용액에는 녹는다. 이것의 나트륨염 형태(sodium urate)가 결석의 대부분을 차지한다. 급성백혈병 치료 초기단계와 통풍(Gout)에서 혈중요산이 급격히 오를 수 있다. |

|---|---|---|---|
| 설명 | 항산성성질(좀처럼 염색이 되지 않으나 한번 염색이 되면 산성용액에 의해서 탈색이 되지 않는 성질)을 가진 균(예를 들면 결핵균 등)의 검출에 이용되는 염색방법. 방법에는 Ziehl-Neelson법과 Kinyoun법 등이 있다. |

| 영문 | nucleic acid | 한글 | 핵산 |
|---|---|---|---|
| 설명 | 염기, 당, 인산으로 이루어진 뉴클레오티드가 긴 사슬 모양으로 중합된 고분자 물질. 유전이나 단백질 합성을 지배하는 중요한 물질로, 생물의 증식을 비롯한 생명 활동 유지에 중요한 작용을 한다. 구성 당인 오탄당이 리보오스인 리보핵산과 디옥시리보오스인 디옥시리보 핵산으로 나뉜다. 펜토스로서 리보스나 데옥시리보스 어느 한쪽만을 포함하며 전자를 리보핵산(RNA), 후자를 데옥시리보핵산(deoxyribonucleic acid, DNA)이라 부른다. 모두 4종류의 유기염기에 의해 특징지어지며 아데닌, 구아닌 및 시토신은 양자에 공통이다. 티민은 DNA에, 우라실은 RNA에 포함된다. DNA는 주로 핵에 존재하며 형질유전에 그리고 RNA는 세포질속에서 단백질 합성에 관여한다. 섭취된 핵산은 소화관에서 구성분자로까지 가수분해되어 흡수된다. |

| wave | 1. An advancing ridge or swell on the surface of a liquid, as of the sea, resulting from the oscillatory motion of the particles composing it when disturbed by any force their position of rest; an undulation. "The wave behind impels the wave before." (Pope) 2. <physics> A vibration propagated from particle to particle through a body or elastic medium, as in the transmission of sound; an assemblage of vibrating molecules in all phases of a vibration, with no phase repeated; a wave of vibration; an undulation. See Undulation. 3. Water; a body of water. "Deep drank Lord Marmion of the wave." "Build a ship to save thee from the flood, I 'll furnish thee with fresh wave, bread, and wine." (Chapman) 4. Unevenness; inequality of surface. 5. A waving or undulating motion; a signal made with the hand, a flag, etc. 6. The undulating line or streak of luster on cloth watered, or calendered, or on damask steel. 7. A swelling or excitement of thought, feeling, or energy; a tide; as, waves of enthusiasm. <physics> Wave front See Undulatory theory, under Undulatory. Origin: From Wave,; not the same word as OE. Wawe, waghe, a wave, which is akin to E. Wag to move. See Wave. Source: Websters Dictionary (01 Mar 1998) |
| wave analyzer | An apparatus that assesses a complex mixture of wave forms by separating out their component frequencies and displaying their distribution. (05 Mar 2000) |
| wave form | The form of a pulse; e.g., an arterial pressure or displacement wave; or of the pacemaker pulse as demonstrated on the oscilloscope under a specified load. Synonym: waveshape. (05 Mar 2000) |
| wave number | <microscopy> The number of waves or cycles of light flux or radiant energy, measured through a distance of 1 cm. (05 Aug 1998) |
| plane wave | <microscopy> Wave in which wavefronts are parallel to a plane normal to the direction of propagation. (05 Aug 1998) |
| plasma wave | <physics> A disturbance of a plasma away from equilibrium, involving oscillations of the plasma's constituent particles and of an electromagnetic field. Plasma waves can propagate from one point in the plasma to another without net motion of the plasma. (09 Oct 1997) |
| compression wave | <radiobiology> Waves where the quantity which oscillates is the density of the medium, that is the medium at a given point alternately compresses and expands. Low-amplitude compression waves in air or water are commonly known as sound waves, shock waves are a high-amplitude form. Synonym: density wave. (13 Jan 1998) |
| postextrasystolic T wave | The modified T wave of the beat immediately following an extrasystole. (05 Mar 2000) |
| C wave | 1. A monophasic positive deflection in the electroretinogram arising in the pigment epithelium of the retina. 2. Wave in the venous and atrial pulses occurring during isovolumic ventricular contraction in which the closed atrioventricular valves (mitral and tricuspid) are abruptly displaced into the atria with a creation of a pressure transient. (05 Mar 2000) |
| x wave | The wave in the atrial or venous pulse curves produced when ventricular ejection moves the floors of the atria toward the ventricular apices. (05 Mar 2000) |
| pulse wave | The progressive expansion of the arteries occurring with each contraction of the left ventricle of the heart. (05 Mar 2000) |
| P wave | The first complex of the electrocardiogram, representing depolarisation of the atria; if the P wave is retrograde or ectopic in axis or form, it is labelled P'. (05 Mar 2000) |
| shock wave | <radiobiology> Wave produced (for example, in a gas or plasma) as a result of a sudden violent disturbance. To produce a shock wave in a given region, the disturbance must take place in a shorter time than the time required for sound waves to traverse the region. (09 Oct 1997) |
| shock wave lithotripsy | A method of fragmenting calculi. (05 Mar 2000) |
